Introduction

THIS OPERATOR ENCLOSURE MEETS THE FOLLOWING STANDARDS: • ISO 8083:1989 11 600J FALLING OBJECTS PROTECTION STRUCTURES (FOPS) • ISO 8084:1993 OPERATOR PROTECTION STRUCTURES (OPS) • ISO 8082-2:2011 ROLL OVER PROTECTION STRUCTURES (ROPS) • OREGON OSHA 437-007-0775:14A TIP-OVER PROTECTION STRUCTURES (TOPS) • ISO 2867:1994 • SAE J1356: FEB. 1988 • OREGON OSHA 437-007-0775:14B,C • AS 4988 2002 * MODIFICATIONS AND REPAIRS: The integrity of the FOPS, OPS, ROPS, TOPS structure and its continued ability to provide the level of protection it was designed for could be seriously affected by any modifications to the structure, its mounting or to the chassis to which it is attached.

Tigercat emphasizes that the certification of approval of the FOPS, OPS, ROPS, TOPS structure will become void if any such modifications take place.

Tigercat may officially grant approval for modifications only by: (i) Written approval of repairs or modifications signed by the Tigercat Engineering Manager; or (ii) Approved modifications officially released by Tigercat.

Both of the above are provided that the work is carried out in the factory approved manner.

Unauthorized modifications and/or repairs made or contributed to by a customer or a Tigercat distributor may result in creating a dangerous situation and therefore the customer or Tigercat distributor will be considered to have assumed the risk involved or be negligent in creating this situation.

Tigercat will not be held responsible for situations arising from having created unauthorized modifications/changes to the structure.

Operator cabs are designed to ROPS, TOPS, FOPS, OPS standards so that they will withstand force and absorb energy during a roll over (ROPS), tip-over (TOPS), when resisting the impact of a falling object (FOPS) and minimize the possibility of operator injury from penetrating objects (OPS). When a permanent deflection of the structure occurs, the structure can no longer provide the original designed level of protection and should be replaced. Attempts to straighten the structure, particularly by the application of heat, can reduce still further the structures remaining capability to protect.

The mounting and the frame or chassis to which the cab is attached is considered an integral part of the FOPS, OPS, ROPS, TOPS and is included in the design, test and certification of the product.

Contact the Tigercat Service department before attempting any modifications or repair to tip-over protective structures.

1.4

Tigercat 855D/L855D Feller Buncher

Safety Do not operate the machine with any defective or inoperable components.

WARNING

Check all fluid levels.

Do not walk on machine surfaces with steel cleated foot wear. Steel cleats on steel surfaces are slippery and do not provide a safe foot hold.

Do not operate the machine with any of the exhaust system, safety covers, oil shields, or other devices removed.

WARNING It is not recommended to walk on machine surfaces that are not designated walking areas.

No attempt should be made to walk on angled steel surfaces or surfaces that are irregular in shape.

Keep a first aid kit in an easily accessible location on the vehicle at all times.

Walking surfaces on the machine must be covered with anti-slip materials to provide a safe foot hold and prevent slipping.

WORKING WITH OIL Direct contact with oil implies a risk of skin complaints (example: eczema). Strict hygiene should be observed.

These anti-slip surfaces should be maintained on a regular basis. If the surface shows signs of wear, the anti-slip material must be replaced immediately.

Some advice which should be observed: • Oils used in this machine may be hot enough to cause serious burns.

To reduce risk of fire, machines should be completely cleaned of debris at least daily, particularly around the engine exhaust components. Hydraulic oil leaks, excess grease, fuel and oil accumulation (including spillage) should be eliminated immediately. Turn off engine before cleaning machine.

• Avoid contact with oil, particularly heated oil.

• Oil on the skin should be washed off immediately with soap and water.

• Wear protective gloves. Hands should be clean before putting on gloves. Apply protective cream to the hands to make washing easier.

Maintain a clean cab interior, clear away trash or debris.

• Do not put oily rags in your pockets.

Machine should be washed completely at every major service.

• Soiled clothing should be changed as soon as possible.

Inspect the machine daily for signs of damage or unusual wear, to structures.

• Keep an extra overall handy, but not in the machine where it can become dirty.

Check for fluid leaks, or faulty operation. Repair or replace malfunctioning parts and systems immediately.

• Cuts and abrasions must be attended to immediately. Clean them and apply first-aid.

Check windows and door guards for damage.

• Avoid breathing in oil fumes.

Check protective windows for cracks. A damaged window has reduced strength to stop flying objects. All damaged windows must be replaced with original equipment.

• Wash hands and arms frequently (example: at each meal break or as often as possible).

• Oily rags and gloves must be safely discarded after use.

Check windows for scratching, crazing and cloudiness that could impair clear visibility all around the machine.

Read, understand and follow all general safety precautions specified by attachment manufacturer.

Safety

Tigercat 855D/L855D Feller Buncher

SAFETY HAZARDS – VITON SEALS

Approach with extreme caution any area where overhanging electrical power lines are present.

Serious injury or death by electrocution can result if the machine or any of its attachments are not kept a safe distance from these lines.

O-rings and other seals manufactured of Viton material (fluorine rubber) produce a highly corrosive acid (Hydrofluoric) when subjected to temperatures above 315°C (600°F).

Maintain a minimum distance of 3 m (10 ft) between the machine, including the boom or attachment, and any power line carrying up to 50,000 V. Add 1.5 m (5 ft) for each 150,000 V increment beyond 50,000 V. For example, if a power line carries 350,000 V, keep back at least 6 m (20 ft).

This contamination can have extreme consequences on human tissue since it is almost impossible to remove after contact.

The following procedures are recommended when inspecting equipment that has been subjected to high temperatures such as fire: • Visually inspect any seals or gaskets which have suffered from heat; they will appear black and sticky.

• If these are found, Do Not Touch!

If State/Provincial, local or job site regulations require even greater safety distances than stated above, adhere strictly to these regulations for your own protection.

If the machine must be transported, make sure that it is adequately secured to the transporting vehicle. Refer to VEHICLE MOVING INSTRUCTIONS in SECTION 2 of THIS MANUAL.

• Determine the material composition of any seals or gaskets. If fluoro-elastomer seals (Viton, fluorel, or tecmoflon) have been used, the affected area must be decontaminated before undertaking further work. Natural rubber and nitrile materials are not hazardous.

Stopping the engine immediately after it has been working under load can result in overheating and premature wear of the engine components.

Reduce engine speed to LOW and let run for approximately five minutes to allow gradual dissipation of heat and also to reduce turbo speed.

This will also prevent loss of coolant by after boil and possible hot spot damage to the engine.

• Disposable heavy duty gloves (neoprene) must be worn and the affected area decontaminated by washing thoroughly with limewater (Calcium Hydroxide solution).

• Any soiled rags and gloves must be safely discarded after use.

NOTE: Burning discarded items is not recommended except in an approved incineration process where the dangerous products are treated by alkaline scrubbing.

SAFETY HAZARDS - OPERATING Maintain a charged fire extinguisher on the vehicle at all times and know how to use it.

Do not carry passengers either in the cab or anywhere else on the machine. The vehicle is provided and approved with seating for the operator only.

Be aware when performing service and maintenance tasks that surfaces and grab handles in and around the engine and cooling system may become very hot when the engine has been running. Contact with hot surfaces may cause injury.

Comply with instructions in this manual and also your company’s regulations for the operation of this machine.

Do not allow anyone who may be unfit, physically or mentally or who may be under the influence of alcohol or drugs, to operate the machine.

When moving the machine, watch that enough clearance is available on both sides and above the machine or any of its attachments. Extra clearance may be required particularly where the ground is uneven.

1.6

Read, understand and follow all general safety precautions specified by attachment manufacturer.

WARNING Engine exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

Safety MACHINE STABILITY AND TRACTION– MACHINES WITHOUT LEVELER

WARNING

When working on slopes, travel straight up or down the slope to prevent roll-over.

Never travel across a steep slope or side hill: • As logs are added to the accumulator pocket the handling and the stability of the machine will change.

• To avoid tip over, keep the attachment as low as possible to maintain a low centre of gravity.

• Be prepared to dump the load in case of an emergency.

Keep the cab doors closed when driving or steering the machine to prevent accidental entry of branches and debris into the cab.

• Do not overload the machine as this can create an unstable condition and cause a roll-over.

Keep the cab doors closed and use seat belt when driving or steering the machine to prevent being thrown from the operator's cab.

Secure loose items in the cab.

Prior to commencing work, check all equipment controls to make sure the machine responds correctly.

Make sure that all safety screens and guards including the escape hatch are installed and properly secured.

Rest the attachment on the ground when operation is stopped, regardless if the engine is running or shut off.

Operate the machine only from a seated position in the operator’s seat.

Watch for ground hazards such as metal debris, wire fencing or rocks.

When travelling, position the attachment and boom so as not to impair vision.

If vision is limited by dust, smoke, fog, rain or snow, stop the machine until visibility is restored.

CAUTION Do not open cab doors or window screens when cab is on a slope. The doors and screens are heavy and could swing out with considerable force injuring anyone in the path. Anyone opening the door or screen and holding on to it could be pulled out of the cab and injured.

MACHINES WITH LEVELER

This machine is designed to operate on rough terrain and slopes commonly found in forestry applications. However, ground conditions vary greatly with changing soil types, slope angles, moisture, snow and ice, rocks, boulders and stumps, and fallen trees. All of these factors affect the machine’s stability against tip-over and traction to resist slipping. This machine may not be capable of operating on some ground conditions, and must be used with caution.

Whenever possible work within the normal working range of the boom system as shown in FIG. 1.

NOTE: In any boom position, both inside and outside of the normal operating range, there is a risk of instability and tipping.

To minimize the risk of tipping observe the following: • Do not attempt to operate this machine on slopes without first receiving proper training.

• Learn the stability limits or “feel” of the machine by first working on gentle slopes and by positioning the boom to reduce the risk of tipping. Gain experience over time by gradually increasing the angle of the slopes on which you are working.

• Keep the attachment as close to the ground as possible to increase machine stability, and to allow the boom to be quickly lowered to the ground should the machine begin to tip.

• Use the LOW speed setting for the track drives when on slopes.

When it is necessary to work outside of the normal working range, be aware the stability of the machine is reduced. The risk of tipping is increased while operating in the reduced stability working range.

Be aware the machine is in its least stable position on a slope with the boom to the rear.

• Travelling at an angle to the slope other than straight up and down decreases the traction of the tracks. Increasing the angle to the slope away from straight up and down can cause the machine to slide sideways downhill and/or possibly tip over.

All efforts have been made in the design of the machine to reduce the risk of tipping, however it is not possible to eliminate the risk of tipping.

Safety

• Never travel across a STEEP slope or side hill.

BOOM TO FRONT

• Carry any load on the uphill side of the machine.

• Do not lift or move objects that exceed machine stability.

• Be prepared to release the load in case it causes the machine to tip.

• Position the cab so that you have a clear view in the direction of travel. Be aware of ground conditions and obstacles in the machine’s path before moving the machine.

• When crossing obstacles (boulders, stumps, ditches etc.) the machine can shift rapidly, greatly affecting the stability of the machine.

Move slowly over obstacles, and position the boom against the ground to reduce the risk of the machine shifting rapidly.

KEEP ATTACHMENT CLOSE TO GRADE TRACK GEAR BOX AT REAR OF UNDERCARRIAGE 845C-007

FIG. 3 CLIMBING SLOPE

• Backing over obstacles unexpectedly while travelling down a slope poses a tipping risk.

Know the path of the tracks whenever the machine is moved.

• When climbing a slope the boom should face uphill and the attachment should be kept close to the ground (FIG. 3). When descending a slope the boom should face down hill and the attachment should be kept close to the ground (FIG. 4). Be particularly aware of machine stability when changing directions on, or travelling back down a slope.

• As you gain experience, recognize the maximum slope on which the machine can operate cannot be defined simply by an angle value. Variables in surface terrain, soil types, rocks, boulders, stumps, and fallen trees, changing weather conditions, and first and foremost the operator’s experience and skill levels greatly affect the maximum slope limitations. Be aware these factors can result in a shallow slope posing greater risk than a relatively steeper slope. Do not attempt to work on slopes beyond your personal capability level.

Safety

Tigercat 855D/L855D Feller Buncher

FLUID INJECTION INJURY

The best defence against suffering the effects of fluid injection is to prevent the accident from occurring in the first place.

WARNING

When searching for possible fluid leaks:

Diesel fuel or hydraulic oil under pressure can penetrate the skin and could result in death or serious injury. If any fluid is injected under the skin, a medical doctor familiar with the treatment of this type of injury must surgically remove it within a few hours.

• Never search for leaks with your bare hands.

Wear thick protective gloves.

Hydraulic and diesel fuel systems on forestry machines operate at very high pressures, often 207 bar (3000 psi) and above. If a loose connection or a defect in a hose should occur, a fine, high velocity stream of fluid will result.

Even for systems pressurized to as little as 7 bar (100 psi), this fluid stream can penetrate human skin as if it were a hypodermic needle.

• Be sure to wear safety goggles for eye protection.

• Keep all body parts well away from the area being investigated for leaks.

• Use the end of a long piece of wood to move hoses or other obstacles.

Initially, an accidental fluid injection beneath the skin may only produce a slight stinging sensation.

There is a danger that you will tend to ignore this, thinking that it will get better with time. Most often, it does not! Within a very short time the wound may begin to throb painfully, indicating that tissue damage has already begun.

Similarly fluid injected directly into a blood vessel can spread rapidly through your circulatory system. The human body has little ability to purge injected fluid.

• Place the end of a long piece of wood in the suspected path of any fluid stream. Never use any part of your body.

Time becomes critical as tissue damage progresses rapidly. The longer you delay getting professional medical attention, the more damage can occur.

• Recognize the source of the leak and the fluid streaming from it may be very small and not easily visible. You may only be able to see the fluid that accumulates as a result of the fluid stream.

Although fluid injection accidents are rare, the resulting injury has on occasion required the amputation of a finger, a hand or in some cases the entire limb. The longer the delay in getting professional medical aid, the further up the limb the tissue damage can spread. An injury of this type can become very serious or even fatal if not dealt with promptly and properly.

When performing any service work • Stop the engine and relieve all diesel fuel or hydraulic pressure before disconnecting any lines or otherwise working on the system.

• Never grab any hydraulic or diesel fuel connectors or hoses when they are subjected to pressure.

In the event of any suspected fluid injection injury: • Report the injury to your supervisor immediately.

• Ensure that hoses are rated for the pressures to which they will be subjected.

• Seek professional medical attention immediately.

• Never use any hoses that you suspect could be defective.

GREASE INJECTION INJURY WHEN USING PNEUMATIC GREASE GUNS Pneumatic grease guns can deliver grease at pressures from 17 – 400 bar (246 – 5801 psi).

It takes less than 7 bar (100 psi) to inject a substance through human skin.

Get professional medical treatment immediately after any type of injection injury.

Provide the physician with information on the type of grease, the pressure setting of the gun, and similar details.

The amount of fluid injected, type of fluid (or material), pressure at which it was injected and the elapsed time between injection and seeking medical attention all influence the chances of successful treatment for this type of serious injury.

Prior to using a high pressure pneumatic grease gun perform the following: • All operators of high pressure pneumatic grease guns must be trained in the hazards of its operations and the treatment for such injuries.

• Do not operate a high pressure pneumatic grease gun unless you have been trained in the proper operation and are aware of all safety precautions of such a tool.

• Wear protective clothing such as gloves, safety hat and safety glasses.

• Inspect all parts of the grease gun for wear and tear and replace all worn or damaged parts.

• Ensure that protective shrouds are installed on all grease gun nozzles as safety devices.

• Remove dirt and grease from grease fittings prior to greasing.

• Replace any defective grease fittings on equipment with new fittings immediately.

• When badly positioned fittings are identified, replace them with angled or swivel fittings for easier access.

LIGHTNING SAFETY AWARENESS WHAT IS A LIGHTNING STRIKE?

LIGHTNING SAFETY

Lightning is a discharge of the electricity produced by a thunderstorm. As the thunderstorm develops, many small particles of ice within the storm clouds bump together. These collisions create a positive charge at the top of a cloud and a negative charge at the bottom. As this continues a second positive charge builds up on the ground beneath the cloud, concentrated around high objects such as hills, trees, buildings, equipment and even people.

When the difference between the electrical charge in the cloud and on the ground becomes great enough to overcome the resistance of the insulating air between them, an electrical current flows instantly. This is a lightning strike.

In spite of the popular myth that being struck by lightning is an unlikely event, the facts show that lightning strikes occur frequently. As a result loggers are at high risk because their work is outdoors and close to known strike points such as tall trees and heavy equipment.

Loggers can increase their chances of avoiding a lightning strike by following a few simple safety practices.

1. Designate a member of your crew to: ▪ Monitor daily weather forecasts ▪ Observe local weather conditions ▪ Alert all other members of the crew when a possible lightning threat develops

The electrical potential in a lightning strike can be as much as 100 million volts. Lightning strikes can occur over very large distances, even as much as 60 km (37 miles). Lightning travels both in front of and behind a thunderstorm and so strikes happen even when rain has not started or has stopped.

Lightning can hit in the same place, many times and often spreads out over 18 m (60 feet) within the soil around the strike point.

2. Don’t start or continue any work that cannot be stopped immediately, when a storm moves nearby.

3. Anticipate a high-risk situation and take action early by moving to a low-risk location. Do not hesitate. If there is lightning, you are in danger.

Thunder accompanies lightning. When lightning occurs, the air through which it travels is instantaneously heated to a temperature more than 28,000°C (50,000°F). The air expands rapidly due to this heating, then quickly contracts as it cools. It is this contracting shock wave that we hear as thunder.

In many areas of the world, lightning strikes are second only to flooding as the greatest cause of storm related deaths and injuries. Although only 10% of lightning strike victims are killed, virtually all from cardiac or respiratory arrest, over 70% of those that survive suffer severe, life-long injury and disability. The symptoms of a lightning strike include memory loss, fatigue, chronic pain, dizziness, sleeping difficulty and the inability to complete several tasks at one time.

4. Obey the rule - If you see lightning, Flee. If you hear thunder, Clear.

5. Do not follow the now obsolete guideline to take shelter when the time between seeing lightning and hearing thunder is 30 seconds or less. This does not provide sufficient time to ensure safety. Follow step 4.

6. Remain in your safe location for 30 minutes after the last sight of lightning or the last sound of thunder.

The safest location during lightning activity is inside a fully enclosed, substantially constructed building, a house, office, school, shopping area, etc. These are the safest because of the electrical wiring and plumbing they contain. Should lightning strike, the electrical current will travel through the wiring or plumbing into the ground. When such a building is nearby, seek shelter there first.

1.28

Tigercat 855D/L855D Feller Buncher

Safety

Unfortunately loggers do not often work close to buildings and therefore other alternatives need to be considered.

WHAT TO DO IF YOU ARE OUTSIDE AND SEE LIGHTNING OR HEAR THUNDER

Sheds, weather shelters, hunting blinds, tents and other partially open or small structures are not safe against lightning strikes as they lack the electrically grounded components of larger buildings. They are intended for sun or rain protection only. Do not seek shelter from lightning strikes inside these structures.

If you can, get inside: Run to the nearest building, motor vehicle or fully enclosed ROPS equipment cab immediately.

Being anywhere outside is not safe.

The second safest location during lightning activity is inside a fully enclosed car, van, truck or bus with a metal roof and metal sides. The electrical energy of a lightning strike to these vehicles is carried to ground by the conducting outer metal surfaces.

This is called the skin effect.

Do not seek safety from lightning strikes in vehicles with fiberglass or plastic body shells or in convertible top vehicles. None of these are safe, as they do not offer skin effect lightning protection.

Heavy forestry equipment such as a skidder, loader, feller buncher, forwarder, etc. with a fully enclosed rollover protective structure (ROPS) cab take advantage of the skin effect and are therefore safe in electrical storms.

However machines with a rollover canopy only are not safe against lightning strikes as they are open to electrically conductive rainwater and do not benefit from the skin effect. Operators of this equipment must abandon their machines and get to a safer location before lightning strikes.

If inside a building: • Don’t watch the lightning storm from open windows or doorways. Stay in inner rooms.

• Stay well away from corded telephones, electrical appliances, lighting fixtures, radio microphones, electrical sockets and plumbing pipes and fixtures.

If inside a motor vehicle or fully enclosed ROPS equipment cab: • Under no circumstances whatsoever step outside of the vehicle or off the equipment to move to another shelter. Very dangerous electrical pathways to ground may go through you.

• Shut down all operation, turn off the engine, close all doors and raise all windows.

• Sit squarely in the seat with your hands in your lap and your feet flat on the floor mat.

• Do not touch any metallic objects referenced to the outside of the vehicle. Do not touch any door and window handles, control levers, foot pedals, steering wheels, cab interior walls and any other inside to outside metal objects.

Note the rubber tires on motor vehicles and heavy equipment do not increase safety from lightning strikes. Lightning has already travelled a great distance through the air to strike the vehicle. In comparison a few inches of rubber in a tire offers absolutely no additional insulation.

• Do not touch any radio or telephone connected to an outside antenna.

1.29

Safety

Tigercat 855D/L855D Feller Buncher WHAT TO DO IF YOU FEEL YOUR SKIN TINGLING, YOUR HAIR STANDS ON END, LIGHT METAL OBJECTS VIBRATE OR YOU HEAR A CRACKLING SOUND:

If you are caught outside and have nowhere to go: • Avoid wide-open areas where you project above the surrounding landscape.

• Seek shelter in a low place, such as a ditch, ravine, valley, canyon or cave.

• Lightning is probably about to strike. You only have a few seconds to act.

• Get away from open water such as ponds or streams.

• Put your feet together. Crouch down like in a baseball catcher’s position. Hold your head down. Cover your ears to protect them against the noise of the thunder.

• Do not take shelter under any isolated tall trees or small groups of trees.

• Seek shelter amongst the dense, thick growth of the shortest trees.

• Do not lie flat on the ground. By touching as little of the ground as possible, the lightning may not move across the ground to you.

• Avoid entering any small enclosures or shelters.

WHAT TO DO IF A CO-WORKER HAS BEEN STRUCK BY LIGHTNING:

• Do not seek shelter under any motor vehicle or heavy equipment.

• The victim does not carry any electrical charge. There is no danger to anyone helping this person. You can touch him or her immediately.

• Keep clear of any materials that can conduct electricity such as wire fences and gates, metal pipes, poles, rails and tools.

• Stay at least 15m (50 feet) away from metal objects such as a fuel tank, a vehicle or machinery without a cab, motorcycle, ATV, etc.

• Stay at least 5m (16 feet) apart from any other members of a group so that lightning won’t travel between you.

• Do not use the telephone except for emergencies.

• Call your local emergency response telephone number immediately.

• If the victim has no pulse, their heart has stopped or they have stopped breathing, start cardiopulmonary resuscitation (CPR) or mouth –to-mouth resuscitation immediately. Use a portable defibrillator if one is available.

• Be careful about staying in the storm to take care of the victim. You can get hit by lightning too. If you can, move the victim to a building as soon as possible.

• To further increase your awareness about lightning safety, see the following web sites: ▪ National Weather Service Lightning Safety http://www.lightningsafety.noaa.gov ▪ National Lightning Safety Institute http://www.lightningsafety.com

FIRE PREVENTION

Clean out all accumulated forest debris (twigs, pine needles, branches, bark, leaves, saw dust, small wood chips) and any other combustible materials from inside the machine belly pans or lower machine structures as well as from areas in proximity to the engine, fuel and hydraulic oil systems no less frequently than at the completion of each work shift.

Inspect the machine regularly for any signs of diesel fuel or hydraulic system leakage. Check for worn or eroded fuel or hydraulic lines before starting up any equipment.

When working in a forest environment, it is impossible to prevent combustible debris from collecting in tight corners of the machine. This debris may cause a fire however, when mixed with fuel, oil or grease in a hot or confined place, the danger of fire is greatly increased.

Clean up any grease, diesel fuel, hydraulic and lubricating oil accumulation and spillage immediately.

Steam clean the engine, hydraulic pumps, transmission, brake, fuel and hydraulic tank compartments and all machine belly pans at least once a month or more frequently when working in logging conditions where large amounts of combustible forest debris are present.

The following fire prevention guidelines should be used to supplement the operator’s fire prevention efforts. In no case should the guidelines be used, or assumed, as replacements for diligent operator efforts at preventing fires.

Use only non-flammable solutions for cleaning the machine and components.

The following guidelines will help to keep your equipment up and running efficiently and keep the risk of fire to a minimum.

Maintain a CHARGED fire extinguisher on the machine at all times and KNOW HOW TO USE IT. Remove debris and blow out dust regularly from the air intake doors, engine radiator and charge air cooler, hydraulic oil cooler, diesel fuel cooler and air conditioning condenser core to prevent overheating of the engine and hydraulics and to maintain efficient operation of the machine. Refer to CLEANING COOLER PACKAGE in SECTION 3.

Blow off all forest debris and fine organic material accumulated near hot engine exhaust components (turbocharger and exhaust manifold as well as exhaust pipes and muffler) at the completion of each work shift or more frequently when working in logging conditions where large amounts of combustible forest debris are present. Visual inspection after blow off to ensure thorough cleanliness is vital. Engine exhaust systems provide numerous small pockets where saw dust, small wood chips and other flammable forest debris can gather. Even small accumulations close to hot exhaust components can ignite and smolder. If dislodged this smoldering debris can fall into other areas of the machine and thereby spread a fire.

Inspect the exhaust system daily for any signs of leakage. Check for worn, cracked, broken or damaged pipes or muffler. Also check for missing or damaged bolts or clamps. Should any exhaust leaks or defective parts be found, repairs must be made immediately.

Engine exhaust leaks can cause fires. Do not operate the machine until the exhaust leak is repaired.

During daily operation of the machine, the occurrence of exhaust leaks are usually accompanied by a change or increase in engine exhaust noise levels. These audible warnings cannot be ignored. Should any exhaust leaks occur during operation, the machine must be shut down immediately and not put back to work until the necessary repairs have been completed.

Park the machine at least 15 METERS (50 ft) away from other equipment at the end of each shift.

Never leave the machine parked with boom, arch or blade suspended off the ground. Should their supporting hydraulic hoses burn through during a fire, pressurized hydraulic oil may be injected into the fire and the boom, arch or blade will fall rapidly to the ground.

Turn the battery disconnect switch to OFF at shut down to de-energize all electrical circuits.

1.31

Safety

Tigercat 855D/L855D Feller Buncher

Remain with the machine for at least 45 minutes at the end of operations while the machine cools.

Remove all keys, lock equipment and fuel cap at the end of operations to reduce the risk of vandalism.

WHAT TO DO TO PREPARE FOR A MACHINE FIRE • Prevent the fire from happening in the first place by ensuring that all machine systems are frequently inspected and well maintained.

• Ensure that any hand held fire extinguishers are charged and in working order. Fire extinguishers require routine care. Follow the manufacturer’s instructions for inspection and maintenance shown on the label of the fire extinguisher and in the extinguisher manufacturer's manual.

• Ensure that any pressurized water systems on the machine (if applicable) are charged and in working order.

• Ensure that you have the proper fire extinguishers on site. Most fires involving mobile forestry equipment will be Class A or B. Dry chemical extinguishers should be rated ABC and pressurized water extinguishers should be rated A.

Be cautious when smoking. An open flame, a lighted cigarette, etc., should not be permitted around any vehicle, especially during fuelling operations or when the fuel system is open to the atmosphere or when servicing batteries.

After transporting (trucking) a machine from one job site to the next, open all doors and access panels and blow off any debris that may have repositioned itself onto the engine and exhaust parts due to wind turbulence caused by the journey.

Before starting repair work, such as welding, the surrounding area should be cleaned and a fire extinguisher should be close by.

Store rags and other combustible materials in a safe, fireproof location.

Do not use the machine on top of or to push piles of burning timber. A machine fire will most probably result.

NOTICE Equipment fires adversely effect your ability to log, may increase your insurance premiums dramatically or prevent you from obtaining insurance coverage at all.

Class A fires involve ordinary combustibles such as wood, cloth, paper, rubber and many plastics, Class B fires occur with flammable liquids such as diesel fuel, oil and grease and Class C fires apply to energized electrical equipment.

• Ensure the nozzle of any hand held extinguisher and pressurized water system available on the machine and at the work site fits within the fire extinguisher access holes in the doors of the machine.

• Ensure that your fire detection system* is in working order. Refer to FIRE SUPPRESSION SYSTEM (OPTIONAL) in SECTION 2.

• Ensure that your fire suppression system** is charged and in working order. Refer to FIRE SUPPRESSION SYSTEM (OPTIONAL) in SECTION 2.

• Ensure that you are familiar with the recommended procedures for fire contained in the emergency action plan of your company.

• Ensure that you follow all national, state/provincial and local regulations dealing with fire fighting in effect in your specific geographic region. Regulations will vary from region to region but most will usually require that: ▪ Workers assigned to fire fighting duties must be physically capable of performing them safely and effectively.

1.32

Tigercat 855D/L855D Feller Buncher ▪ Workers designated to use fire fighting equipment as part of an emergency action plan must receive full and proper training from a qualified instructor.

▪ Whenever portable fire extinguishers are provided for use in the workplace, training must be provided to familiarize workers with the general principles of fire extinguisher use and the hazards involved with fire fighting.

▪ Training must be provided upon initial employment and at least annually thereafter.

• Ensure that after you have received the training as outlined above, that you know how to use the fire extinguisher, the pressurized water system (if applicable) and the fire suppression system** on your machine. There is not enough time available to read instructions during a fire emergency.

• Ensure that all information necessary for you to immediately contact all sources of help (local fire department, etc) in the event of a fire emergency is recorded and readily available at all times.

Safety WHAT TO DO WHEN A MACHINE FIRE OCCURS

If operating the machine when a fire occurs:

1. Lower all working attachments to the ground.

2. Shut the engine off.

3. Activate the fire suppression system**.

4. Radio or call for help. Be certain to report a fire immediately.

5. Exit the machine taking fire extinguisher and pressurized water system hose (if applicable) with you.

6. At all times ensure your own personal safety and the safety of anyone that may be in the area. Approach any fire with extreme caution. All fires can be very dangerous and life threatening.

7. Only if you can safely do so, turn OFF the battery disconnect switch.

Before deciding to fight the fire, be certain that: 8. The fire is small and not rapidly spreading.

9. There is a clear, safe escape route to your back.

10. You have received training in the use of the available fire extinguishing systems and are confident that you can operate them effectively.

11. If in any doubt about whether or not to fight the fire – don't. Instead stand well clear of the fire and wait for help to arrive.

12. Be aware hoses containing engine coolant, diesel fuel or hydraulic oil could fail during a fire. If this happens, hot coolant, fuel or oil could possibly be ignited by the fire.

13. If possible a dry chemical fire extinguisher or fire suppression system** should be used first to fight a machine fire. Then immediately afterwards use the pressurized water hose supplied with the machine (if applicable) or a pressurized water extinguisher (if available). A fire suppressed by dry chemical may re-ignite from the heat retained by any debris or hot machine components in the area. The water will cool the area, reducing the chances of re-ignition.

1.33

Safety ▪ Use the PASS method. This is the most effective use of a fire extinguisher. ▫ Pull the pin at the top of the extinguisher that keeps the handle from being pressed. Break the plastic seal as the pin is pulled.

Tigercat 855D/L855D Feller Buncher WHAT TO DO AFTER A MACHINE FIRE HAS OCCURRED

Before returning the machine to work.

1. Ensure the cause of the fire is determined and all appropriate repairs are completed.

▫ Aim the nozzle at the base of the fire. Do not aim the nozzle at the flames. In order to put out the fire, you must extinguish the fuel, not the flames. Hose nozzles are often clipped to the extinguisher body. Release the hose before taking aim. ▫ Squeeze the handle to release the pressurized extinguishing agent. The handle can be released at any time to stop the discharge. ▫ Sweep from side to side at the base of the fire until the fire is completely out or the fire extinguisher is empty

2. Ensure the fire detection system* or the fire suppression system** is properly serviced and in working order (if applicable).

3. Ensure that all extinguishers used in fighting the fire are replaced or recharged.

• Notify your equipment dealer and/or Tigercat Industries Inc. by completing an incident report, Tigercat form number 5101. *NOTE: Fire detection systems are offered by Tigercat as an optional installation on some Tigercat product lines. Please disregard any references made to fire detection systems if not installed on your machine. **NOTE: Dry chemical fire suppression systems are offered by Tigercat as an optional installation on some Tigercat product lines. Please disregard any references made to fire suppression systems if not installed on your machine.

20229A

TYPICAL FIRE EXTINGUISHER ACCESS HOLE ▪ Place the nozzle of the fire extinguisher into the appropriate fire extinguisher access hole and discharge the extinguisher.

▪ Only if you can safely do so, open the access panels to the machine in the area of the fire.

▪ Failing all attempts to access the machine compartment, discharge the extinguisher through the mesh or any available openings on the machine.

▪ Ensure the machine and all components have cooled down sufficiently after a fire so that re-ignition does not occur.

▪ Remain with the machine until help arrives.

1.34

Tigercat 855D/L855D Feller Buncher DRY CHEMICAL CLEANUP PROCEDURES

CAUTION In areas exposed to moisture, the dry chemical powder will combine with water to form a paste that is mildly acidic. Note that all surfaces covered by this dry chemical paste including electrical contacts are vulnerable to corrosive attack.

IMPORTANT! To neutralize the acidic paste on large surfaces, spray or wash these areas with a mixture of 3 parts hot water to 1 part baking soda. Allow this mixture to stand for several minutes before rinsing with warm water. Wash the area with a mild soap and water solution. Rinse thoroughly with water. Blow-dry to remove all residual water.

Safety Cleaning of electrical contacts should be done using an electrical contact cleaner that has no flash or fire point and is non-corrosive and non-conductive such as CRC Contact Cleaner 2000.

In areas exposed to heat during the fire, the dry chemical powder will melt forming a coating that cakes or crusts on all surfaces.

To break down the caked dry chemical, spray or wash these areas with a 50/50 mixture of hot water and Isopropyl alcohol. Allow this mixture to stand in place for several minutes.

The caked dry chemical when exposed to moisture is also mildly acidic. When the break down procedure has been completed, neutralize the dry chemical.

Both ABC dry chemical fire extinguishers and fire suppression systems discharge a chemical powder to extinguish the fire. The chemical makeup and the small particle size of the powder as well as the force of the discharge all contribute to the fire fighting capability.

These same characteristics also permit the powder to penetrate into and fully cover all components in the vicinity of the discharge.

The following are recommendations for the cleanup and neutralizing of areas exposed to dry chemical powder.

Workers performing this work should wear protective clothing, safety goggles and a fine particle dust mask to minimize their personal exposure to the dry chemical powder.

Ensure that all electrical systems have been completely de-energized prior to any cleanup.

In areas of the machine that remained cool and dry during the fire, the dry chemical will stay in powder form.

Be certain to clean these areas immediately to prevent any settled residual powder from coming into contact with moisture whether through direct contact or humidity in the air.

Remove the powder residue by blowing off with air, sweeping, dusting or vacuuming using a HEPA filter capable of trapping the small dry chemical particles.

Then wipe all surfaces with a damp cloth.

SAW24

Track Feller Buncher – Sudden Machine Movement May Cause and Unexpected Throw at the Cab

Tigercat wheel feller bunchers and track feller bunchers can be supplied with several optional makes and models of high speed disc saw tree felling heads. Because each head has unique characteristics, advantages and disadvantages, they are chosen based on the specific types of work they were designed to complete.

A.2

Tigercat

Using High-Speed Disc Saws Safely

STORED ENERGY

OTHER INSTRUCTIONS

The saw blade stores energy from the hydraulic motor between tree cuts so it can supply up to 1000 hp during a one second tree cut. However, this rotational energy, if misapplied, can result in wood materials or other objects being thrown strongly enough to cause damage and injure people.

All instructions contained in the operator and service manuals for use and maintenance of Tigercat disc saw heads and other disc saw heads installed on Tigercat machines must be read, understood and followed.

BE AWARE OF THE HAZARDS

Here are the most common means by which a rotating disc saw can cause harm by throwing:

DANGERS

Users of machines with disc saw felling heads must be aware of all safety precautions. In this section, some previously unknown, unexpected safety hazards are illustrated and explained. These should be studied before use of the machine and then reviewed again after use has begun.

• The normal throwing of chips from the cut.

• Soil particles are thrown from the ground.

• Loose chunks of wood encountered or produced are tossed by the exposed blade.

• Sticks and debris falling onto the blade or sliding across the blade are struck by the teeth and thrown.

SAFE PRACTICES It is understood and expected that logging organizations and operators must develop and practice additional rules to suit particular conditions of terrain, trees, soil and job requirements. The information provided in this section is intended to assist towards a quicker understanding of how and why things can happen when a high speed disc saw is in use and to assist in the development of safe operating practices.

• Metal pieces from the blade or from encountered objects are thrown.

• Wood pieces enter the saw housing and are expelled by the blade.

• In very peculiar cases the saw can throw long lengths of wood as spears.

It should not be assumed that all possible dangers have been discovered and described in this section.

HOUSING TYPES TYPE OF HOUSING MAKES A DIFFERENCE Since the configuration of the saw housing can affect the safety of its use, we need to identify some particular types of housing shapes and guarding being used.

HOUSING WITH SNOUTS A

B

SAW13

A Throw Angle

SAW17

Saw Housing with Snouts B Snouts

This commonly used saw housing is designed with a continuous skirt around the saw except at a mouth opening where the trees are cut and taken. The skirt extends below the saw enough to intercept tangential throws. There are snouts on both sides of the mouth to prevent the saw teeth from making contact with the wood if pushed against the side of a felled tree or log.

A.4

Tigercat

Using High-Speed Disc Saws Safely

HOUSING WITH NO SNOUTS A

B

SAW14

SAW15

Saw Housing with No Snouts

A Throw Angle

B Housing Plan with No Snouts

This housing has no blade-guarding snouts. This allows the saw blade teeth to protrude ahead of the housing.

This may be preferred for dexterity in tree getting.

HOUSING WITH LONGER INGOING SNOUT A

C

B

B

SAW12

A Throw Angle B Long Snout

SAW18

Saw Housing with a Longer Snout on the housing Ingoing Side C Short Snout

This housing has a much longer snout on the ingoing side of the mouth, i.e., where the teeth of the rotating blade are entering the housing. The broad side of a log, if nudged, will not contact the saw teeth and more thrown material will be intercepted by the extra length of the snout.

A

A

E

D A

SAW19

A Throw Angle B Rear C Front

A

SAW20

A SAW26

Saw Housing with Additional Opening

D Opening in Housing Skirt E Guard for Chip Escape Port in Housing

This housing incorporates an additional opening (chip escape port) in the housing skirt to allow for the discharge of wood chips produced by the saw teeth in the cut and being taken into the housing.

A guard is available to close the chip escape port so tangential travel of chips and other material is intercepted as soon as it leaves the housing.

The various housing types show a shaded area where normally tangentially thrown material can escape from the saw housing. Deflected and dropped chips escaping below the bottom edge of the housing skirt are not included. The areas and angles are not exact but do show that one head can be different from another.

IMPORTANT! The operator must be familiar with the blade rotation direction, the effectiveness of any snout on the in-going side and which direction a chip escape port allows material to discharge.

COMMENTS AND INSTRUCTIONS

ASSESSING THE POTENTIAL DANGERS ON THE JOB SITE

RECOGNIZING THE DANGERS

The extent of danger from high speed disc saws on a logging operation must be assessed on the job site, depending on how much other work activity is in the area and whether the operator can do their job of cutting and bunching with good control of throw patterns. Danger is greater if the saw is equipped with detachable, or fragile, or brittle teeth, or if the site contains stones or abandoned metal.

While it may appear the illustrated danger areas (throw angle) can be visually recognized on the job by observing how far chips are discharged during a cut, this only holds true for chips and other light weight materials.

Metal parts and wooden spears can be thrown to surprisingly greater distances. Even distant personnel on the ground, in other vehicles, or in buildings are at risk if the throw is in their direction.

REGULAR MAINTENANCE

DIRECTION OF THROW

Poor saw maintenance increases possible dangers.

Some designs, that might allow fasteners to wear thin or fatigue and suddenly break, need thorough timely replacement procedures. It is important the warning signs of missing saw tooth parts or the sounds of striking rocks be heeded and the operation adjusted to avoid danger.

The direction of possible tangential throw for metal parts and stones is dependent on the housing configuration and might be expected to be the same as observed for the chips. However, these throws can occur at any time the saw is running, in whichever direction the throw angle is pointed by boom geometry, and not just when a cut is being made.

THROW DISTANCE The throw distance for metal pieces and stones, can be many times the distance shown by the pattern for chips.

More testing and data collection is needed to pin down a 'safe distance' but if someone or something is in a place that can be seen by the operator and in the throw direction of a high speed disc saw, then the operation is not safe regardless of the distance.

SAFE OPERATING AREAS These saw heads must not be used in areas where the logging operation does not have control over the presence and movement of people. In particular, clearing of vegetation in urban and populated areas should not be done with a Tigercat manufactured or supplied high speed disc saw. High speed disc saw heads are intended for high productivity wood harvesting in areas remote from normal habitation. The possible presence of people and property within throw range and the likelihood of encountering scrap metal, wire fencing, steel posts and concrete must be respected.

Disc Saw Felling Head with High Angle Wrist Rotation Capability

A Long Snout on Outgoing Side

B Discharge Paths

It is essential that the housing have a long snout on the ingoing side and, if equipped with a chip escape port, it should be guarded.

With these high mechanical freedom arrangements, there is a chance that an unforeseeable operator misadventure or equipment failure could result in an accidental direct or deflected throw at the operators cab. The cab should be capable of resisting such accidental and ricochet throws. The velocity energy of metal or rock pieces leaving the blade is extremely high. The operators cab cannot be considered safe to routinely operate in the chip throw area, even if it has been constructed to prevent penetration by accidentally thrown objects.

THROWING LONG WOOD PIECES

A

Dangers from throws of long wood pieces are illustrated throughout this portion of the document.

Tests and experience have shown that, when a high speed rotating saw is applied to a loose piece of wood, the wood is either blown or pushed away, without a throw.

C

If the wood is held firmly in all directions, and the saw is advanced into the wood at any feed speed, cutting will take place. If the wood is only restrained against the saw radially, but not restrained tangentially, then the wood will be both partly cut and partly moved tangentially.

If the piece of wood is backed-up by a solid slippery surface, the feed in is very fast, and the piece of wood is long enough, the tangential movement is a dangerous spear-like throw.

A slab, still partly attached to a well backed-up tree bole and wet with sap, makes an ideally bad throw situation which could unintentionally occur in woods work.

If the side of a log can contact the saw blade, the throw engagement distance can be long.

A Saw Throw Gap

A Felling Head Moving Into Stump (Feed Speed)

Blocks of wood can be tossed in any direction when improvising with a disc saw to trim over-size stumps. A long snout and a slow feed speed lessen danger during stump trimming. A similar danger of throw may exist when clearing small brush with multiple pass cuts.

Saw blades have gaps between adjacent teeth and holders to permit installation and removal of the teeth and to provide spaces to accumulate chips in the cut.

Fallen sticks and debris, or sticks and debris sliding across the saw blade, can enter these gaps when the blade is rotating and may be struck by the teeth. This will cause the sticks and debris to be tossed or thrown.

Larger gaps and lower rotation speeds increase these dangers.

SAW22 SAW22A SAW22B

A Ingoing Opening of the Saw Blade Housing

Saw Bade Entrance and Exit Space

B Outgoing Opening of the Saw Blade Housing

To avoid the ingestion of materials into the housing space above the disc (and later ejection) the ingoing entrance for the saw rim of teeth is kept as small as practical. It is important that this high wear area be maintained at its original size and shape.

The outgoing opening is large enough to allow the housing to clean itself and allows most things inside to be thrown out. Its throw direction and angle must be respected. A long snout on the ingoing side reduces this danger.

A.13

Using High-Speed Disc Saws Safely

Tigercat

This information is offered by Tigercat as part of interim action to make saw heads safer. It is based on what has recently been reported from the field and on tests conducted on proving grounds.

• Do not assume visitors and other workers are aware of disc saw dangers.

• Do not assume the operator will spare you, a visitor, from danger.

Tigercat continues to design and test tree felling machinery towards achieving greater safety in the woods. Tigercat would be thankful for written reports describing any unsafe happenings, including near misses, in the use of felling heads and their carriers.

• Do not select and operate heads that throw rearward.

• Do not select and operate heads with unnecessarily wide throw angles.

THE FOLLOWING ARE SOME SAW HEAD DO NOT'S THAT APPLY PARTICULARLY TO THROW PREVENTION:

• Do not neglect to read and follow all instructions provided by the saw and head manufacturers.

• Do not point the throw of a disc saw head in a direction towards people, vehicles or buildings at any visible distance.

• Do not operate in a way that throws chips in a direct line at the machine cab.

• Do not push hard with the saw against anything except a standing tree to be cut.

• Do not mix new sharp teeth with old dull teeth on the same saw.

• Do not change the blade rotation from its designed direction in the head.

• Do not over speed the blade rpm.

• Do not remove or shorten snouts provided by the head manufacturer or installer.

• Do not neglect tooth fastening inspection, maintenance and replacement.

• Do not neglect to repair worn or damaged saw housings.

• Do not neglect to replace any covers removed for service or clean out.

• Do not count on skis to give the throw protection that snouts do.

• Do not nudge loose short pieces with the front of any type of head.

• Do not nudge anything, even long logs, with the front of a head which has no snouts.

• Do not cut short small stalks when the blade speed is low.

• Do not operate a high speed disc saw in a populated area.

COOLING FAN – SWITCH (B) This is a three position switch, labeled AUTO CLEAN / AUTO / FULL ON. This switch along with an electronic fan control module, controls the operation of the hydraulic fan.

AUTO POSITION – AUTO Auto is the normal operating position for the fan control switch. When the switch is in the AUTO position, the fan will operate completely in an automatic mode. It will start, speed up or slow down all based on the temperature of the charge air, engine coolant and/or the temperature of the hydraulic oil. The electronic control module automatically adjusts fan speed to the minimum required level to maintain optimal operating conditions, and default to fan at full speed if an error in the controller exists.

When the switch is in the AUTO position and the fan runs at minimum speed due to low charge air, engine coolant or hydraulic oil temperatures, turning ON the A/C will cause the fan control to increase the cooling fan speed when engine is at high speed. This is to ensure that sufficient air flow is available for the cab A/C even while the machine is still warming up.

2.20

Tigercat 855D/L855D Feller Buncher

Controls and Operation

FULL ON (OVERRIDE) – DOWN POSITION

CLEAN – UP POSITION

When the switch is in the FULL ON (OVERRIDE) position, the fan control system is overridden and the fan will run at FULL speed for cooling regardless of charge air, coolant or oil temperatures. Normally the fan control switch is placed in the AUTO position for optimal cooling.

The FULL ON (OVERRIDE) position is intended for use in the event of a temporary failure of the fan control.

Momentarily pressing the switch to the CLEAN position will automatically start reversing the direction of fan rotation (there is no need to hold the switch down). Reverse rotation is used to clean the charge air cooler, radiator, oil cooler, A/C condenser and air intake door screens. By reversing the flow of the fan, air flow is propelled in the opposite direction, thereby forcing dust and debris off the radiator.

NOTE: Placing the switch in the FULL ON position activates the computer alarm to advise the switch has been placed in the FULL ON position. Also while the switch is in the FULL ON position the Automatic Cleaning cycle is prevented.

NOTE: The pilot system must be ON to operate the clean cycle.

CAUTION Before placing the fan switch in the CLEAN position make sure there are no personnel near the rear of the machine in the area where the fan will expel debris.

WARNING

The electronic fan control will also turn the A/C system OFF for as long as the fan is in the CLEAN mode.

When the CLEAN cycle is complete the fan automatically returns to normal rotation direction.

NOTE: The CLEAN cycle also operates automatically via the timed purge function of the computer control system (frequency is adjustable) when the switch is in the AUTO position. Refer to COMPUTER – MAIN MENU – ADJUST MENU – MACHINE PARAMETERS in THIS SECTION.

For leveling machines that work on slopes, select the system cooling fan switch FULL ON position if the following product support bulletins (PSB) have not been completed: PSB 2580 (revision 2) PSB 2669 Selecting fan FULL ON prevents the system from activating the timed purge function, which may cause the machine to coast down the slope.

Controls and Operation

Tigercat 855D/L855D Feller Buncher

ER MODE – SWITCH (C) This is a two position momentary switch that allows the operator to toggle ER ON or ER OFF. This machine can be switched from ER boom to non-ER boom operation. The boom and load will move when this switch is made.

Never permit persons to stand under boom or attachment. Contact could result in death or serious injury.

Ensure attachment is resting securely on the ground before performing any of the following functions: 1. Activating ER switch valve.

AUTOMATIC OPERATION

DISCHARGE OF THE SYSTEM

There are seven thermostats mounted in the engine and hydraulic enclosures which are wired to the control panel. The thermostats are automatic heat detection devices and are set to close at 177°C (350°F). When a thermostat closes it sends an electrical signal to the control panel which activates the fire suppression system.

When an electrical signal (automatic or manual) is received by the control panel it sends a discharge signal to the electrical actuator located on top of the pressurized cylinder. When activated the electrical/pneumatic actuator extends a control shaft which mechanically opens the agent cylinder valve. This releases the dry chemical in the discharge area protected by the system. The control panel will also automatically shut down the engine and all electrical power.

The fire suppression system can also be activated manually using the manual actuation switch.

To manually operate the system: 1. Safely lower the boom to the ground.

2. Pull locking pin (A).

3. Press red FIRE button.

NOTE: The engine does not shut down automatically when the fire suppression system is activated using the nitrogen actuator. When using the nitrogen actuator to activate the fire suppression system the operator must shut the engine off manually.

The automatic engine shutdown feature will either shutdown the engine immediately the fire suppression system is discharged (non-leveling machines) or will delay the shutdown for a period of between 10 to 15 seconds for leveling machines. The time delay period is a factory setting. This delay feature allows the operator to lower the load or move the machine to a safer location before the engine shuts down. The operator can extend the engine shutdown delay feature by pressing the RELAY RESET button on the control panel to repeat the preset delay period.

This button can be pressed repeatedly until the operator has brought the machine to a safe stop.

The RELAY RESET button does not delay the discharge of the fire suppression system.

An electrical signal is sent to the control panel from the manual actuation switch which activates the system.

NOTE: In the event of a power failure the system can be activated by the Nitrogen Actuator located on the front left post of the cab.

1. Remove Locking Pin (A).

2. Strike down hard on actuator knob.

Controls and Operation

WEEKLY:

BI-YEARLY:

1. Inspect all parts for damage, rust, corrosion or dirt. Replace any damaged parts immediately.

1. Check the system owners manual for correct re-certification intervals. These are required for insurance policy.

2. All components are in place and unobstructed.

3. All chemical delivery hoses and nozzles are connected and tight.

4. Check fire suppression electrical network for cut, frayed, stripped or damaged wires.

AVOIDING DAMAGE AND FALSE DISCHARGES DURING MACHINE SERVICE: Pay attention to the location of the components of the fire suppression system. Take care not to damage heat sensors or wiring, this includes hitting, cutting, bending, denting, etc. Damage to heat sensors due to shock could cause an accidental discharge of the system. Cut, pinched, or kinked wiring could cause false signals and an accidental discharge of the system.

In addition thermostats are sensitive to heat from welding torches, steam cleaning or other outside sources which may create a false discharge of the system.

If any of the components are damaged, replace them immediately before operating the machine.

H845D-014

5. Ensure thermostats are clean.

6. Operate the machine and press the “Push to TEST” button to confirm the automatic engine shutdown feature is working. Pressing the “Push to Test” (Amerex diamond) button will illuminate all LEDs, sound the alarm and engage the relay. The “Push to Test” function will not cause a system discharge.

It is also important to take care around the chemical cylinder. The chemical cylinder is pressurized and can explode if struck with sufficient force. Pressurized cylinders are extremely hazardous.

WARNING Failure to follow the system manufacturers instructions and guidelines may result in serious bodily injury, death, and property damage.

A Side Door Emergency Exit

This side door serves as one of two emergency exit routes from the cab. Turn OFF the engine before using this exit. Opening the side door will not deactivate the pilot system, for this reason only use this door in an emergency. In the event that it cannot be used, use the emergency escape hatch in the roof of the cab.

The purpose of the vacuum pump system is to hold the hydraulic oil in the tank when servicing pumps and other hydraulic components, minimizing oil spill. When activated, a solenoid valve closes off the hydraulic tank breather air supply. The pump removes tank air to create a vacuum, which then holds the oil in the hydraulic tank. This system eliminates the need to drain the hydraulic tank beforehand.

With the ignition key OFF, activate the vacuum pump by placing the vacuum pump switch in the ON position.

NOTE: When the ignition key is in the RUN position, the vacuum pump system will not start.

Alternatively if the vacuum pump is on, the engine cannot be started. The vacuum pump also will not start if the battery disconnect switch is in the OFF position.

2.33

Controls and Operation

• Seat is too high/seat too low

• Rides is too stiff/seat tends to push or throw operator forward

Adjust seat to the desired position. If the proper height cannot be achieved using the height adjustment lever, it may be necessary to install the seat on a higher base.

The air ride control valve has over-pressurized the seat air suspension. This typically happens because the operator is trying to use the air suspension to adjust the ride height rather than using the height adjustment lever to raise the seat.

• Operator’s legs falling asleep The seat is adjusted too high, and the air ride control valve has under pressurized the seat air suspension ride adjustment, resulting in the operator sitting in a bucket.

• Rides is too soft or bottoms out.

The air ride control valve has underpressurized the seat air suspension ride adjustment. Insufficient pressure exaggerates the knee-action movement of the seat. This usually happens because the operator is trying to lower the seat by decreasing the amount of air pressure instead of using the height adjustment lever.

NOTE: The aftertreatment system and its related components are applicable to Tier 4f machines.

This message will be displayed, alarm light will flash and alarm will sound when an aftertreatment technical fault is detected. Action to correct the problem should be taken immediately to avoid affecting engine performance and damage to the diesel oxidation catalyst/selective catalytic reduction (DOC/SCR) aftertreatment system components.

This message will be displayed, alarm light will flash and alarm will sound when this engine has idled for more than one hour. Shutdown engine to prevent damage to the emission control system.

This message results in the following derate sequence if no action is taken to correct the problem: •

• • • •

Beginning immediately after an aftertreatment system technical message there will be a ramp down of Torque by 25% over 25 minutes.

After 1 hour at reduced torque there will be a ramp down of Engine Speed by 60% and Torque by 65% over 40 minutes.

After 50 minutes at derated engine speed and torque the engine is derated to idle within 30 minutes.

Some less severe technical faults can be fixed at any time, even after then engine has been fully derated to idle speed.

More severe technical faults will result in an engine lockout when the engine has derated to idle and there have been three restarts (re detects).

3. Turn ignition key switch to the RUN position. The WAIT TO START icon below will appear on the display during the “key ON” engine pre-heat time. Heating elements (grid heater elements) located in the engine air intake manifold are turned ON to heat the intake air when starting the engine. The engine must not be started until this icon turns OFF automatically.

Controls and Operation NOTE: If the engine does not start after three attempts, check the fuel supply system. Absence of blue or white exhaust smoke during cranking indicates no fuel is being delivered.

IMPORTANT: After engine has started, keep engine speed low until engine oil pressure registers on the computer display. If it does not register within 10 seconds, stop engine and investigate cause.

Allow a cold engine to warm up at LOW engine speed for at least five minutes before applying any load. Check all engine parameters on the MD3 display often during the warm up period.

CAUTION Do not attempt to start engine by shorting across starter terminals as personal injury could occur. Start engine only from operator’s seat.

WARNING Do not use ether! Engine is equipped with an electrical starting aid. Use of ether may cause an explosion and severe injury.

NOTE: For cold weather conditions refer to COLD WEATHER STARTING and MACHINE PREPARATION, SYSTEM TEST AND WARM-UP in THIS SECTION.

4. Then turn ignition key switch to the START position

to crank engine.

5. When the engine starts, release the ignition key switch to the ON position.

NOTE: If the engine does not start after three attempts, check the fuel supply system.

6. Set throttle to LOW engine speed and wait three to five minutes before operating with a load.

IMPORTANT !

Engine should not idle longer than one hour.

Damage to the emission control system will result. When this machine idles for an extended period excess hydrocarbon buildup is created in the DOC/SCR aftertreatment system. Burn off of excess hydrocarbon at full load immediately after a long idle period will generate excess heat which will cause damage to emission control system components.

7. Increase engine speed (rpm) slowly to provide adequate lubrication to the bearings and allow oil pressure to stabilize.

If engine stalls while operating the machine, turn the ignition key switch to the OFF position and REPEAT STEPS (1) to (5).

engine

Ensure the saw blade has stopped rotating before leaving the cab. (p) Leave the cab and visually check hose connections and cylinders for leaks. Check under the machine for oil leaks.

WARNING

NOTE: The computer control system on this machine has a warm up mode function which limits engine speed and applies the anti-stall during cold starts. Refer to WARM UP MODE in THIS SECTION for more information. (g) Slowly raise and lower the stick boom and the main boom, check for proper operation.

With the felling head raised slightly off the ground:

Never use your bare hand to check for fluid leaks.

Fluid leaks under pressure may not be visible.

When searching for leaks, wear work gloves and use a wrench or piece of wood to move hydraulic hoses. Do not grab hold of hydraulic hoses. Wear safety goggles for eye protection.

(h) Operate the accumulation and clamp arms and check for proper operation. (i) Tilt the felling head forward and back and check that it is operating correctly. (j) Swing the upper structure to the left and right. (k) When cold weather conditions exist, continue the process of warming up the hydraulic system by repeating steps (g) to (j) several times. As the hydraulic system warms up, engine speed can be increased gradually to the HIGH position. If the FILTER BYPASS message comes on decrease engine speed immediately and continue warming the system.

Controls and Operation

STOPPING ENGINE IMPORTANT! Stopping the engine immediately after it has been working under load can result in overheating and premature wear of the engine components. Follow the stopping procedure outlined below to allow the engine to cool.

Follow this engine shut down procedure. The important benefits are: • Extended life of engine, cooling and exhaust systems.

IMPORTANT! Only use the battery disconnect to shut off a running machine in an emergency. A fault code will be logged by the ECU on the engine for improper shut down and power down.

9. Perform daily maintenance at the end of the shift (greasing, clean engine compartment etc.). This allows the machine time to cool down while under the watchful eye of the operator.

• Reduced risk of post shutdown fires.

• Interior of machine cools significantly reducing risk of touching hot surfaces.

1. Turn the saw switch to the OFF position and STOP the attachment. This should be done before leaving the cutting area.

2. Find a clear and level area at least 15 m (50 ft) from any other equipment to park the machine.

3. Park the machine and lower the attachment onto firm ground.

4. Reduce engine speed to LOW , de-activate the pilot system and let engine run at LOW speed for approximately three minutes minimum to allow dissipation of heat and also to reduce turbo speed. This will also prevent loss of coolant by after boil and possible hot spot damage to the engine.

5. Open power roof and place fan switch in Full ON position.

6. Do not increase engine speed before shut-off.

7. Place fan switch in AUTO position.

8. Stop engine by turning ignition key switch to the OFF position.

NOTE: Whenever the engine is stopped all DEF solution is pumped back to tank before the engine power system is turned off. This process takes approximately 90 seconds.

Refer to AFTERTREATMENT SYSTEM in SECTION 3 of THIS MANUAL for more information.

NOTE: This machine is equipped with an After Run/Accessory Relay which delays the power disconnect to engine related fuses and relays (ECU /ATS relay, NOx Sensor relay, NOx Sensor fuse, ECU Power fuse, DCU fuse) by 90 seconds.

Controls and Operation TRAVELLING (BOOM RAISED) 1. Select the appropriate drive range.

Place the track switch in the LOW or DRIVE position.

When in LOW the machine moves slower but with increased drive force. All logging operations should be done in LOW. When in DRIVE the machine moves faster but with less drive force. Travelling over longer distances should be done in DRIVE to allow for faster travel speeds when the terrain permits. Also, do not travel continuously for longer than 10 minutes, take 5 minute breaks, this will help prevent the track drive gearboxes from over heating.

For a more detailed description of drive range refer to TRACK, LOW/DRIVE SWITCH in THIS SECTION. 2. Place swing brake switch in OFF position.

3. Move throttle control to the HIGH engine speed position.

4. Operate the drive foot pedals to manoeuvre the machine.

Tigercat 855D/L855D Feller Buncher OPERATING TIPS WITH LOAD SENSING When using the controls on a load sensing system be aware of what the load sensing system is trying to do for you. If you move the lever or pedal 20% of its total angle, the system will provide whatever pressure it takes (up to its maximum capacity if needed) to meet this speed requirement. If you move the lever past the point needed in an attempt to speed up the boom movement, you will only overshoot the speed you wanted. Relax and try to use the least amount of lever action you can.

Load sensing systems respond to rough operation by amplifying these movements. If you find the boom is jerky or giving “feedback”, you’re probably too active on the controls. If slowing down doesn’t eliminate the roughness, the margin pressure setting may be too high and can be reduced to calm down the machine’s response.

Refer to SET MARGIN PRESSURE in SECTION 4 of the SERVICE MANUAL. Refer to SET FLOW (FUNCTION SPEED) RATE in appropriate BOOM, SWING or TRACK DRIVE sections of the SERVICE MANUAL.

A Normal horizontal reach motion performance can be expected in this area B Operating the hoist boom in this zone with a full load will not allow the horizontal reach motion to perform as it should without assistance from the right joystick

This ER boom system is designed to minimize heat generation and fuel consumption during horizontal boom motion. To obtain maximum benefit from the system, the machine should be operated using mainly horizontal reaching motions as much as possible, lifting and lowering the boom only as much as necessary for positioning until the head is full.

Due to the nature of this ER boom system, there will be certain conditions in which the weight of the head plus its carried load will be too great for the system to provide its intended horizontal reaching motion. This most notably occurs when the machine is operating on a hill with the head raised higher than the tracks and tucked in close to the cab. If such a situation occurs, the right joystick control should be pushed forward slightly while operating the left joystick to get the system moving. To help prevent this situation, the head should be kept as close to the ground as possible and slightly extended when climbing hills.

TIGERCAT FLUID ANALYSIS PROGRAM Using the Tigercat Advanced Fluid Analysis Program on a regular basis is an excellent preventative maintenance tool.

Studies have shown that it is possible to receive a 10 to 1 payback when looking at the amount saved on repair costs to the amount invested in a scheduled fluid analysis program. Some of the benefits of a sampling program include: • Detect problems early before they become major catastrophic failures.

• Better ability to schedule downtime and forecast cost of repairs.

• Monitor maintenance schedules and practices and confirm the required maintenance is being done on time.

• Increase used equipment value by providing proof of proper maintenance.

This Program uses the most modern technology available to analyze all fluid samples. Most test results are available within 24 hours after receipt of the sample and are supplied in an easy to understand report, which calls for specific action and makes detailed recommendations. This report is available as a mailed or faxed hardcopy, sent via e-mail or can be viewed on the internet.

This program will provide Tigercat machine owners access to an Advanced Fluid Analysis Program for all major machine components including Engines, Hydraulic Circuits, Axles, Final Drives, Gearboxes, etc.

Lubrication and Maintenance TIGERCAT FLUID SAMPLING PROGRAM

Tigercat 855D/L855D Feller Buncher Hydraulic Oil Samples

FLUID SAMPLE COLLECTION PROCEDURES Fill out the Sample Information Form (SIF) completely and accurately. When taking multiple fluid samples, fill out all of the required SIF`s in their entirety, prior to taking any fluid samples. Then, immediately package each completed SIF together with the matching fluid sample in the black outer shipping container as each individual sample is taken. This will reduce the possibility of mixing up or incorrectly identifying the SIF`s and fluid samples. Incorrectly identified samples could result in a false warning alarm.

The accuracy of the lab analysis results is very dependent on the quality of the fluid sample taken.

Collection of clean fluid samples that are representative of the main body of fluid are essential if meaningful lab results are to be obtained. Erroneous readings may result if proper collection, handling, packaging and shipping practices are not followed prior to the sample being tested by the lab. To be able to accurately compare and trend the lab results over time, all followup samples should be consistently taken from the same location using the same techniques as all previous samples.

• All sample valves and drain plugs must be clean and free of debris.

• Remove the dust cover from the sample valve and attach the bleed hose (supplied with the machine) to the sample valve connection.

• Remove the sample bottle cap only when ready to obtain the sample. Keep the cap clean – do not put it in your pocket or let it get contaminated in any way.

A Hydraulic Sample Valve B Return Manifold

• Hydraulic oil samples should be taken from the circulating oil flow at operating temperature, with no functions actuated, using sample valves that are permanently located on the machine whenever possible.

• Purge the bleed hose before taking a representative oil sample. Drain a minimum of 90 – 120 ml (3 – 4 oz) of oil into a separate container and discard this oil using approved recycling methods.

• Remove the bleed hose and replace the dust cover on the sample valve immediately after taking the oil sample and sealing the sample bottle.

Gearbox Samples • These samples can be taken during the oil change process.

• Do not allow any airborne dirt, etc., to enter the sample bottle.

• To obtain a representative oil sample, the oil must be warm and must not have settled (within 30 minutes of shutdown).

• Avoid contamination of the sample – replace the sample bottle cap immediately after filling the bottle to approximately ¾ full.

• Place the required drain container under the machine to capture the used oil to be discarded using approved recycling methods.

All samples taken should be immediately forwarded to the lab for processing.

Contact your Tigercat dealer to purchase additional or replacement hydraulic sample valves or drain plugs.

• Remove the drain plug and allow approximately 50% of the oil to drain, then place the sample bottle in the stream of draining oil to obtain a representative sample.

In cases where fluid samples must be pumped or otherwise drawn out of a tank or housing, a hand operated fluid suction pump is also available from your Tigercat dealer.

• Inspect the EXHAUST BLANKET and EXHAUST SYSTEM DAILY for any signs of leakage. Check for worn, cracked, broken, or damaged pipes or muffler.

Also check for missing or damaged bolts or clamps.

Should any exhaust leaks or defective parts be found, repairs must be made immediately. Engine exhaust leaks can cause fires, do not operate the machine until the exhaust leak is repaired.

CAUTION All handles, steps and platforms must be kept free of grease, oil, fuel, mud, snow, ice and forest debris.

• Clean around fill caps before checking or adding fluids.

• During daily operation of the machine, the occurrence of exhaust leaks are usually accompanied by a change or increase in engine exhaust noise levels. These audible warnings cannot be ignored. Should any exhaust leaks occur during operation, the machine must be shut down immediately and not put back to work until the necessary repairs have been completed.

• Clean around hydraulic fittings before breaking connection. Plug or cap immediately.

• Clean up all spills immediately.

• Release pressure in hydraulic tank before breaking a connection. For machines with pressurized tanks.

• Have a fire extinguisher at hand.

• Use clean oil and containers.

• For safety, lower boom to the ground when leaving cab, leaving machine unattended or during service.

• Drain dirty oil while still warm.

• Do not exceed recommended fluid levels.

• Install door safety struts when working on machine.

• Service all hydraulic strainers and filters after the failure of a pump, motor, cylinder or valve. Failures of this nature could contaminate the entire hydraulic system.

• Clean fire suppression system sensors.

• Top up diesel fuel at each shift to reduce contamination by condensation.

• Before welding on machine, be sure to disconnect all electrical connections and follow all servicing safety precautions as outlined in WELDING, PRIOR TO in SECTION 1 in THIS MANUAL.

CHECK EMERGENCY EXITS, MONTHLY: • Two alternate exit routes are provided: side door emergency exit and roof escape hatch/emergency exit. These are only to be used if the front door cannot be opened.

• When welding, secure ground connection as close to working position as possible to prevent arcing across machined surfaces or through bearings.

• It is therefore essential these emergency exits be checked at least once per month to ensure they are fully operational.

• Refer to EMERGENCY EXIT MAINTENANCE GUIDE in SECTION 2 of THIS MANUAL for checking procedure.

• Clean away all branches, bark and chips. Clean up all traces of oil to avoid fires. *OIL LOST FROM LEAKAGE LOST OIL (LITRES) LEAKAGE RATE ONE DROP IN TEN SECONDS ONE DROP IN FIVE SECONDS

FIRE PREVENTION

IMPORTANT!

Maintaining your machine properly will greatly extend its life and reduce your operating costs.

PRESSURIZED HYDRAULIC TANK

Fire can result in a machine loss which can be financially devastating.

A

CAUTION After transporting (trucking) a machine from one job sight to the next, open all doors and access panels and blow off any debris that could have re-positioned itself onto the engine and exhaust parts due to wind turbulence caused by the journey.

845C-097

845C-001

B

Before servicing the hydraulic system, open the air vent valve (A) to release air pressure from the hydraulic oil tank.

1. Pine needles and bark when allowed to accumulate, form a fuel source that when ignited is extremely difficult to extinguish. A thorough program of regular cleaning and washing will reduce the possibility of a fire starting. In the event a fire does start, the regular cleaning program will improve the chances of successfully extinguishing a fire.

Air vent valve is open when handle is parallel to valve.

Air vent valve is closed when handle is perpendicular to valve (shown).

After service is complete, close the air vent valve and add air pressure to the hydraulic tank using the Schrader valve (B). Make sure the air is clean and dry. Do not exceed 34.5 kPa (5 psi).

Refer to HYDRAULIC TANK PRESSURIZATION INSTRUCTIONS in THIS SECTION for details.

2. Pay close attention to wiring and plumbing routing during maintenance, ensure that ALL wiring harnesses or hydraulic hoses are properly restrained and clamped to prevent damage from chaffing.

3. Read the fire suppression system manual and have the system serviced regularly by qualified personnel.

4. In case of fire lower the boom system to the ground and shut off the engine before discharging the fire suppression system.

Also refer to FIRE PREVENTION in SECTION 1 of THIS MANUAL for additional information.

Lubrication and Maintenance

SCHEDULED MAINTENANCE For service and replacement intervals see SERVICE AND LUBRICATION SCHEDULE in THIS SECTION.

FREQUENTLY • Check for water in the fuel filter bowl or prefilter • Visual engine check.

• Check engine cooling air intake enclosure screens for possible restriction • In broad leaf applications it may be necessary to reverse the cooling fan as frequently as every 10 minutes.

• Check for debris, snow and ice buildup on emergency exits and remove accumulation immediately • ER Boom system: Periodically, the hoist boom must be lifted up as far as it will go and then lowered to operating height in an area free from overhead obstructions in order to circulate hydraulic oil from the cylinders back through the cooler and filters. This oil does not circulate through the cooler or filters during normal horizontal motion and the oil does not get completely changed during normal vertical motion, so it is important that this procedure be followed at least once every hour.

ER BOOM SYSTEM WARNING This machine is equipped with an ER boom system. Because of this, it may behave in an unexpected manner compared to a conventional boom system.

When performing maintenance procedures or setting up a machine equipped with an ER boom system, the following points must be noted: The hoist and stick cylinders circuits are connected hydraulically. Thus, disconnecting a hydraulic line to a boom cylinder may cause either boom to move unexpectedly. The booms may also move unexpectedly if a port relief adjusting screw is unscrewed (counterclockwise) too far and the pressure drops below that which is required to hold the weight of the booms and attachment. Ensure the attachment is resting squarely on a solid footing and the stick cylinders are fully extended, tank pressure is relieved and engine is shut off before disconnecting any hydraulic lines.

Before attempting to disconnect hydraulic hoses or perform work on the boom system, ensure that: • The machine is parked on level ground with the attachment on the ground (FIG. 1).

• The stick cylinders are fully extended (FIG. 1) or the hoist cylinder fully collapsed (FIG. 2).

For additional safety precautions refer to ER BOOM SYSTEM PRECAUTIONS in SECTION 1 of THIS MANUAL. NOTE: Because of the hydraulic connection between the hoist and stick cylinders, the hoist cylinders can overpower the stick cylinders under certain conditions, causing the stick boom to move unexpectedly. This most often occurs when setting the HOIST BOOM UP relief valve, causing the stick cylinders to extend, but it may also happen at other times if the relief settings are not correct. Ensure that all personnel and equipment are clear of the boom path and there is sufficient overhead clearance for the head to rise before making any adjustments.

Lubrication and Maintenance SWITCHABLE ER BOOM FUNCTION

WARNING This machine is equipped with an ER boom system. Because of this, it may behave in an unexpected manner compared to a conventional boom system.

These machines are equipped with a switchable ER valve to provide ER boom function or non-ER boom function. This function is switched on or off by a button switch and the Computer Controller. For complete details refer to ER BOOM SYSTEM, SPECIAL OPERATING INSTRUCTIONS in section 2.

Pay attention to the following when servicing the ER Boom System. Certain hydraulic circuits on this machine are inter-connected in order to provide level head-travel and to recirculate hydraulic oil to reduce heat generation and fuel consumption. As a result, disconnecting hydraulic lines from one cylinder may release pressure in a different cylinder at the same time. Before attempting to disconnect hydraulic hoses or perform work on the boom system, ensure that: 1. The machine is parked on level ground with the attachment on the ground (FIG. 1).

2. The stick cylinders are fully extended (FIG. 1) or the hoist cylinder fully retracted (FIG. 2).

3. If the attachment has been removed make sure the tip of the stick boom is supported (FIG. 2).

Tigercat does not recommend the pre-filling of spin-on filters due to the risk of damage to the hydraulic system caused by unfiltered oil. Unfiltered oil used to pre-fill filters enters directly into the hydraulic circuit. Contaminants in unfiltered oil can cause significant and costly damage to hydraulic system components.

The cleanliness of hydraulic oil cannot be guaranteed unless it is pre-filtered before use.

Use of filters other than genuine Tigercat replacement filters is not recommended. Replace filters at the recommended time intervals. Refer to scheduled maintenance in this section.

Located at the left of the upper structure behind the cab.

The hydraulic tank (1) has a capacity of 227 L (60 US gal).

Sight gauges (2) mounted on the rear of the tank accessible through the left side door indicate the level of the hydraulic oil in the hydraulic tank.

Incorporated into the base of the top gauge is a low level switch connected to the computer. An Alert message is displayed and the hydraulic oil level icon displays in YELLOW when the oil level falls to this point. The master alarm and alarm light will sound and flash three times.

Use a thermometer to check surface and system temperatures to ensure it is safe to begin service work.

A second oil level sight gauge located in a LOWER position on the tank than the first sight gauge also incorporates a low level switch connected to the computer. A Critical message is displayed and the hydraulic oil level icon displays in RED if there is a further loss of oil down to this point. The master alarm and alarm light will sound and flash continuously. STOP the vehicle, check for leaks and fix if needed, refill hydraulic oil tank to suggested level.

Do not begin service work until the surface or system temperature has cooled down to below 38°C (100°F)!

Keep the hydraulic oil level to within 50 cm (2 in) of the HIGH mark. A low hydraulic oil level can result in severe damage to pumps.

Hot hydraulic oil and hot machine surfaces can cause serious burns!

Before servicing the machine, allow the hydraulic system and machine surfaces to cool down.

Six full-flow filters (3) are connected to the hydraulic tank and mounted on three filter heads with built-in bypasses.

The filters are located on the right side of the hydraulic tank.

3.34

Tigercat 855D/L855D Feller Buncher A temperature sender (4) mounted on the filter side of the tank activates the temperature gauge on the computer. The hydraulic oil temperature icon displays blue when cold and changes to white in normal operating temperature. should the temperature rise above normal the icon changes to yellow.

A critical message is displayed when the oil temperature gauge needle enters the red zone and the icon changes to red. Stop the vehicle and resolve the cause of the fault.

Lubrication and Maintenance HYDRAULIC TANK PRESSURIZATION INSTRUCTIONS Before servicing hydraulic system, release air pressure from tank using air vent valve.

Releasing hydraulic tank pressure in the event of a hose breakage may reduce oil loss. To release pressure from the hydraulic tank: Wearing eye protection, release air from the hydraulic tank by opening the AIR VENT VALVE. Pull valve handle down 90° to open. Push valve handle up to close.

NOTE: Expelled air from vent valve will blow accumulated loose debris in the enclosure.

IMPORTANT! Air vent valve must be opened before changing hydraulic filters and strainers or performing any other service on hydraulic circuits. Do not operate machine with the air vent valve in the open position.

During a filter change or return hose replacement, air is able to enter the return hydraulic circuit.

It is important to bleed as much of this air as possible out prior to restarting the machine. See HYDRAULIC OIL RETURN FILTERS "filter change procedure" for instructions on bleeding air from return circuit. Air bubbles in the hydraulic system will damage the pumps.

After service is completed, close air vent valve and add air pressure from a clean air source to the hydraulic tank via the Schrader valve. Do not exceed 34.5 kPa (5 psi).

OPEN PLUG TO VENT AIR FROM THE SYSTEM

Check to ensure the hydraulic oil type selected in the computer program matches the oil type being used. Adjust oil type if needed. This will allow the program to optimize the cooling and warnings functions to best suite the oil being used.

Refer to OIL GRADE SELECTION in SECTION 2 or SECTION 6 of the SERVICE MANUAL, for selecting hydraulic oil type setting procedure.

It is strongly recommended that a program of regular oil testing be used. Oil change intervals can be established from oil test results.

NOTE: Changing strainers, filters and replacing the hydraulic oil tends to aerate the oil. For maximum pump life, the machine should sit for one hour after servicing to allow entrained air to escape from the oil prior to applying working pressures to the pumps.

When replacing air conditioning system components, it is important to replace PAG oil that has been lost when parts are changed. The total amount of PAG oil added to compensate for replacement components should not exceed the total capacity. Low PAG oil levels can starve the compressor for oil and lead to compressor failure. Too much PAG oil can hurt the cooling performance.

The system should be charged with R134a refrigerant only. Polyalkylene Glycol (PAG) oil should be present in the system and must be used on o-rings and fittings during assembly.

IMPORTANT! It is recommended that when the A/C system is not in use (during cold weather), that it be run for a period of five minutes every two weeks. This will circulate oil to all components of the A/C system.

When installing a new oil filter, do not pre-fill with engine oil as this may result in engine damage. This type of failure is not warrantable by the engine manufacturer.

Refer to the SERVICE AND LUBRICATION SCHEDULE in THIS SECTION for the proper filter replacement interval.

The fuel filter/water separator is a combination unit, with a replaceable fuel filter and a removable water sediment bowl on the bottom of the unit. The water sediment bowl is only replaced if it becomes damaged or non-functional. For service and replacement intervals see SERVICE AND LUBRICATION POINTS in THIS SECTION. If the fuel supply is dirty, the fuel filter must be replaced more frequently than recommended in the owner’s manual. Operating the machine with a clogged fuel filter will result in low engine power. It is also recommended the fuel/water separator bowl be drained daily.

When installing a new fuel filter, do not pre-fill with diesel fuel, or engine fuel pump damage will result. This type of failure is not warrantable by the engine manufacturer.

Unfiltered fuel used to pre-fill filters enters directly into the fuel system. Contaminants in unfiltered fuel can cause significant and costly damage to the engine. The cleanliness of fuel cannot be guaranteed unless it is prefiltered before use.

IMPORTANT! Filters that are an integral part of the engine (fuel and lubricating oil) should be serviced and replaced according to the engine manufacturer's operation and maintenance manual.

AIR FILTER ELEMENTS

The air cleaner on this machine uses 2 filter elements, a primary element and a safety element.

To ensure maximum engine protection, it is important the elements be serviced correctly and at proper servicing intervals.

In addition to the LUBRICATION AND MAINTENANCE SCHEDULE outlined in THIS SECTION, the following instructions should also be noted: The most common and most damaging air intake servicing problems are: PRECLEANER OPERATION

OVER SERVICING

How it works:

Filter elements increase in dust cleaning efficiency as dust builds up on the media. Looks can be deceiving. A filter that looks dirty is actually more efficient than one that is clean. A filter with dust build up on the media reaches nearly 100% dust cleaning efficiency. Only when a filter is so clogged with dirt that air restriction goes beyond engine manufacturer's guidelines, should a filter be replaced.

1. Air enters the underside of the dome through screened louvers, which prevents clogging by blocking any particles larger than the ejection slot from entering the unit.

2. Curved particle accelerator blades slam air and dirt up against the sidewall.

3. Blades along the interior surface move heavier-than-air debris towards the ejection slot.

NOTE: This does not apply to hydraulic oil or diesel engine filters.

4. Clean air continues to swirl down into the engine air inlet pipe.

IMPROPER SERVICING

The engine air precleaner cleans engine air before it reaches the air cleaner filter elements.

It removes contaminants such as dust, powder, insects, rain and snow. This precleaner is self powered and self cleaning requiring virtually no maintenance. However, it should be checked daily to make sure that foreign materials have not plugged the intake area or the exhaust port area of the precleaner.

Engine exposure to dust during servicing is the largest single reason for engine damage due to dust.

Abrasive dust can easily enter the intake system once the air cleaner cover and protective filter element is removed for replacement. The safety element does reduce this risk but it should also be replaced at every third primary element change.

3.70

Tigercat 855D/L855D Feller Buncher IMPORTANT STEPS TO FOLLOW WHEN CHANGING FILTER ELEMENTS

Lubrication and Maintenance AIR CLEANER UNLOADER VALVE

• Release the cover latch gently to reduce the amount of dust dislodged.

• Avoid dislodging dust from filter element(s) by gently pulling the element off the outlet tube.

• Clean the sealing surface of the outlet tube before inserting a new filter element.

• Clean the inside of the outlet tube.

• Check your old filter. It can help you detect foreign material on the sealing surface that is causing leakage.

NOTE: Filter elements should never be cleaned and reused. Cleaning causes dust to bypass the filter and be deposited on the inner surface of the filter media. The dust is then drawn directly into the engine.

5. Inspect the new filter for damage.

6. Insert the new filter properly. Apply pressure to the outer rim of the filter not the flexible centre.

7. Inspect connections and ducts for air tight fit.

Ensure that all clamps, bolts and connections are tight. Check rubber elbows for splits or wear points and replace as needed. Leaks in these locations send dust directly to the engine.

UNLOADER VALVE 855D-028

This rubber valve on the tube of the air cleaner housing should be checked before every shift (8 hrs). If this valve is missing, damaged or has turned hard, it will cause the air cleaner to become ineffective. The valve should be replaced every 1000 Hours.

Remove the unloader valve from the tube of the air cleaner housing. A good valve is soft and flexible.

Check and clean the valve. If it was plugged, then check the filter elements as they may need to be replaced as well. Reattach the valve to the tube.

The valve should suck closed at about ⅓ of full throttle. When operating in high dust conditions this valve should be checked and squeezed frequently to release dust buildup.

Lubrication and Maintenance

Tigercat 855D/L855D Feller Buncher

INTAKE TUBING AND JOINTS Inspect the intake connectors for cracked hoses, loose clamps, or punctures which can allow dirt and debris to enter the engine. Tighten or replace parts as necessary to make sure the air intake system does not leak. Check all hanger bracket hardware and repair or replace immediately.

Replace all air intake rubber connector components every 2000 hours. High temperatures in this area can cause the rubber to harden and crack.

NOTE: high-temperature silicone connectors do not need to be replaced unless they are damaged.

THE AFTERTREATMENT SYSTEM AND ITS RELATED COMPONENTS ARE APPLICABLE TO TIER 4F ENGINES ONLY.

AFTERTREATMENT SYSTEM The engine on this machine is equipped with a combination Diesel Oxidation Catalyst (DOC) and high efficiency Selective Catalytic Reduction (SCR) aftertreatment system to limit the nitrogen oxide exhaust gas values (NOx) to meet Tier 4f emission standard requirements with low fuel consumption. This process is electronically controlled by the DENOX 2.2 system.

The DOC uses oxidation at high temperatures to convert carbon monoxide (CO), hydrocarbons (HC) and the soluble organic fraction (SOF) of diesel particulates into inert compounds, carbon dioxide (CO2) and water vapour (H2O). In addition the DOC converts nitrogen oxide (NO) into nitrogen dioxide (NO2). Increased NO2 levels enhance the performance of the SCR catalyst at low temperatures and increase the effectiveness of the DOC/SCR aftertreatment system as a whole.

The high efficiency SCR process is based on a series of chemical reactions which involve the reaction of ammonia with the oxygen in the exhaust gas to reduce nitrogen oxides (NOx) in the exhaust gas by transforming it into inert compounds: free nitrogen (N2) and water vapour (H2O). In addition the high efficiency catalytic converter includes a clean up catalyst (CUC) which reduces any excess ammonia (NH3) which may result from the SCR process.

IMPORTANT !

Engine should not idle longer than one hour. Damage to the emission control system will result. When this machine idles for an extended period excess hydrocarbon buildup is created in the DOC/SCR aftertreatment system. Burn off of excess hydrocarbon at full load immediately after a long idle period will generate excess heat which will cause damage to emission control system components.

IMPORTANT! When cleaning the machine with pressurized water it is important to avoid getting water directly or indirectly into the exhaust tube. Water in the exhaust tube will damage sensors and SCR system components and affect the proper operation of the aftertreatment system and the engine.

Humidity Sensor Air Filter Supply Module DEF Quality Sensor DEF Level Sensor DEF Tank Heater Valve (Circulating Engine Coolant) Dosing Module Mixer Tube DOC SRC

The DOC/SCR aftertreatment system is electronically managed by the DENOX 2.2 system incorporated into the engine control unit (ECU). The ECU calculates and adjusts the flow rate of the DEF solution into the system based on current engine speed, torque delivered, exhaust temperature, amount of nitrogen oxides and ammonia present.

The exhaust passes through the DOC which uses oxidation at high temperatures to convert carbon monoxide (CO), hydrocarbons (HC) and the soluble organic fraction (SOF) of diesel particulates into inert compounds, carbon dioxide (CO2) and water vapour (H2O). It also converts nitrogen oxide (NO) into nitrogen dioxide (NO2) which enhances the performance of the SCR catalyst.

The supply module pump picks up the DEF solution from the tank and sends it under pressure to the dosing module (DEF injector) to be injected into the exhaust at the outlet of the DOC and pass through the mixer tube upstream of the catalytic converter.

L M N O P Q R S T U

Catalytic Converter CUC NOX Sensor NH3 Sensor Engine Temperature Sensors NOX Sensor Exhaust Flap Engine ECU DEF Dosing Module Filter

The first phase of the SCR process takes place in the first part of the catalytic converter: high temperature exhaust gas evaporates the DEF solution instantly and, by hydrolysis, converts it into ammonia (2NH3) and carbon dioxide (CO2).

Evaporation of the solution lowers exhaust gas temperature, bringing it closer to the optimum temperature required by the process.

The exhaust gas and ammonia at the proper reaction temperature, are introduced into the catalytic converter, where the second phase of the process takes place: by reacting with the oxygen in the exhaust gases the ammonia is converted into free nitrogen (N2) and water vapour (H2O).

Finally the high efficiency catalytic converter incorporates a Clean Up Catalyst (CUC) which reduces any excess ammonia (NH3) which may result from the SCR process.

DEF is used by the DOC/SCR aftertreatment system to lower the concentration of nitrogen oxides from the diesel engine exhaust.

Diesel Exhaust Fluid is an aqueous urea solution with 32.5% high purity urea and 67.5% deionized water.

NOTE: DEF may also be referred to as AUS32 or AdBlue. All DEF must be American Petroleum Institute (API) Certified DEF or meet ISO 22241 specifications.

IMPORTANT! DEF should be stored between – 11°C (12°F) and 30°C (86°F) and out of direct sunlight to maximize shelf life and to avoid DEF quality problems caused by improper storage.

It is important to avoid contamination of the DEF when filling the tank as this may cause costly damage to the aftertreatment system components and affect the proper operation of the aftertreatment system and the engine.

NOTE: DEF quality problems may result in derating of engine performance to meet emission standard requirements. Action to correct DEF quality problems should be taken immediately to avoid affecting engine performance and damage to the DOC/SCR aftertreatment system components.

Refer to COMPUTER DISPLAY MESSAGES in SECTION 2.

NOTE: Whenever the engine is stopped, all DEF is pumped back to tank before the engine power system is turned OFF. This process takes approximately 90 seconds.

Refer to DIESEL OXIDATION CATALYST / SELECTIVE CATALYTIC REDUCTION AFTERTREATMENT SYSTEM in THIS SECTION for more information regarding the use of DEF and its function in the DOC/SCR aftertreatment system.

DIESEL EXHAUST FLUID (DEF) HANDLING AND STORAGE

USE OF PROPER STORAGE CONTAINERS • To prevent contaminants from affecting DEF quality, it should be handled only in storage, transport and filling containers intended exclusively for that purpose.

Diesel exhaust fluid (DEF) is an aqueous urea solution with 32.5% high purity urea and 67.5% deionized water.

NOTE: DEF may also be referred to as AUS32 or AdBlue and should meet ISO 22241 specifications. Use only DEF meeting this standard.

• Polyethylene or stainless steel containers are recommended. Refer to DEF manufacturer's recommendations.

It is important to avoid contamination of DEF as this may cause costly damage to SCR system components and affect the proper operation of the SCR system and the engine.

• DEF is corrosive to metals other than stainless steel.

Transport in metal containers other than stainless steel will result in contamination.

When a problem with DEF quality is detected information messages will be shown on the computer display.

PROPER STORAGE CONDITIONS TO MAXIMIZE SHELF LIFE • DEF should be stored between – 11°C (12°F) and 30°C (86°F) and out of direct sunlight to maximize shelf life and to avoid DEF quality problems caused by improper storage.

NOTE: DEF quality problems may result in derating of engine performance to meet emission standard requirements. Action to correct DEF quality problems should be taken immediately to avoid affecting engine performance and damage to SCR aftertreatment system components.

• DEF quality problems can often be avoided with proper storage and handling practices to maximize shelf life.

Refer to COMPUTER AND DISPLAY MESSAGES in SECTION 2.

• DEF storage areas should be out of direct sunlight and away from heat sources to avoid reducing shelf life.

For safety information refer to DIESEL EXHAUST FLUID (DEF) in SECTION 1.

• DEF shelf life is limited. It should be consumed on a first in first out basis, within manufacturer's recommended shelf life limits. DEF beyond manufacturer's recommended shelf life limits may not meet ISO 22241 specifications.

AVOID DEF QUALITY PROBLEMS WITH PROPER HANDLING PRACTICES Most DEF quality problems can be avoided entirely with a little care and proper handling of DEF. • Clean the area around the fill cap and avoid introducing contaminants into the DEF tank when filling.

• Use only DEF that meets ISO 22241 specifications.

Use of any other fluid will contaminate the aftertreatment system and may pose a safety hazard.

620E-089 855D-048

A Catalytic Converter

The catalytic converter is located above the engine.

Chemical reactions inside the catalytic converter reduce nitrogen oxides (NOX) in the exhaust gas.

The catalytic converter is equipped with soundproofing material and replaces the exhaust silencer. It incorporates both the selective catalytic reduction (SCR) and the cleanup catalyst (CUC) components of the aftertreatment system.

The humidity sensor is located on the air intake just past the air cleaner. This sensor monitors the temperature and humidity of intake air sending signals to the DENOX 2.2 control system. This information is used to calculate the amount of DEF to be injected into the system.

TEMPERATURE SENSORS

The first phase of the SCR process takes place between the DOC and the SCR. High temperature exhaust gas evaporates the DEF solution instantly and, by hydrolysis, converts it into ammonia (2NH3) and carbon dioxide (CO2).

Evaporation of the solution lowers exhaust gas temperature, bringing it closer to the optimum temperature required by the process.

The exhaust gases and ammonia, at the proper reaction temperature, are introduced into the SCR, where the second phase of the process takes place. By reacting with the oxygen in the exhaust gases, the ammonia is converted into free nitrogen (N2) and water vapour (H2O).

Finally the high-efficiency catalytic converter incorporates a clean up catalyst (CUC) which reduces any excess ammonia (NH3) which may result from the SCR process.

620E-087

Temperature sensors are mounted at the inlet of the diesel oxidation catalyst, the inlet of the catalytic converter and the outlet of the catalytic converter. These three sensors send exhaust temperature signals to the DENOX 2.2 control system. The control system uses this information to calculate the amount of DEF to be injected into the system.

NOTE: All three temperature sensors are identical, however location should be noted for analysis purposes when replacing a temperature sensor.

The NH3 sensor is mounted at the outlet of the catalytic converter. The NH3 sensors detect and send information about the NH3 levels in the exhaust. This information is used to calculate the amount of DEF to be injected into the system and to monitor DOC/SCR aftertreatment system operation.

Refer to APPROVED ANTI-SEIZE PASTES FOR EXHAUST/AFTERTREATMENT SENSORS in THIS SECTION.

The inlet NOX sensor is mounted upstream of the diesel oxidation catalyst. The outlet NOX sensor is mounted at the outlet of the catalytic converter. The NOX sensors detect and send information about the dosing of DEF solution and the efficiency of the catalytic converter to the DENOX 2.2 control system. This information is used to calculate the amount of DEF to be injected into the system and to monitor DOC/SCR aftertreatment system operation.

Each NOX sensor consists of a ceramic sensor and an electronic control unit linked by a cable. The sensor detects the concentration of nitrogen oxides in the exhaust. The sensor, cable and control unit are considered to be one part for service/replacement purposes.

NOTE: Cable length cannot be changed as this will affect the proper operation of the sensor.

IMPORTANT! When checking or replacing any sensor or plug in the exhaust or the aftertreatment system, it is important to use only approved anti-seize as specified by Tigercat.

Use of non-approved compounds can affect the operation of the NOX and NH3 sensors and cause a malfunction of the aftertreatment system. This may result in poisoning of the SCR catalyst and require replacement of expensive aftertreatment system components.

CARE OF POLYCARBONATE WINDOWS IN CAB Some windows used in the cab are made from a polycarbonate resin thermoplastic. This material is a replacement for glass when improved strength, durability and safety is required.

INSPECTION AND MAINTENANCE Daily inspection and maintenance is essential to confirm the window’s ability to protect the operator has not been compromised.

• Inspect all windows daily and immediately after any impacts.

Polycarbonate material is expected to resist heavy impact and to absorb high levels of energy when contacted by high velocity thrown objects such as wood chips, cutter tools or stones.

• Check for any damage to the window material or steel structure in the area of the window mounting.

• The edges of the polycarbonate window must be evenly and fully supported on a flat surface around the entire window opening at all times.

Bent or dented skylight structures must be replaced immediately. Bent or dented cab structures must be evaluated immediately for possible repair or replacement.

The extreme operating environment seen in logging applications heightens the need to regularly inspect and properly maintain polycarbonate cab windows.

Polycarbonate windows are an essential piece of operator protective equipment and should be maintained as such. It is important to note that cracks, chips, notches or scarring anywhere on the viewing surface or edges of the window will decrease ability to resist heavy impacts and therefore compromise effectiveness as operator safety protective equipment. Windows with these defects must be replaced immediately.

• The edges of the polycarbonate window must be free from cracks, chips, notches or scarring and must not be pinched or stressed. These defects will decrease ability to resist heavy impacts. Windows with these defects must be replaced immediately.

• Cracks, chips, notches or scarring anywhere on the viewing surface of the window will decrease ability to resist heavy impacts.

Windows with these defects must be replaced immediately.

• Bent, dented or missing window retaining parts must be replaced immediately.

• Rubber materials used in mounting the window must be maintained in good condition.

• Identification of the polycarbonate originally used by Tigercat is hot stamped in a corner of the window to identify its composition. Do not use any replacement window without proof of its material composition. Do not substitute with any other materials.

• Skylights, cab structures, windows and window retaining parts must not be modified or replaced with components that are not approved by Tigercat.

RESISTANCE TO CHEMICALS

CLEANING INSTRUCTIONS

The resistance of polycarbonate material to chemical exposure varies widely. Fortunately, polycarbonate materials have good resistance to diesel fuel, grease, hydraulic oil, kerosene and engine oil.

The viewing surfaces of polycarbonate cab windows are specially treated with a hard coating to provide enhanced resistance to abrasion and ultra-violet (UV) radiation.

Other chemicals however can seriously weaken the polycarbonate.

Do not permit any of the following chemicals to come into contact with polycarbonate windows: • acetone • air conditioning refrigerant • ammonia

The following instructions are provided to prolong the life of this protective hard coating.

1. Rinse the window thoroughly with lukewarm water 2. Using a soft cloth, cellulose sponge or chamois, gently wash the window with a mild solution of soap or detergent in lukewarm water. Do not scrub or use brushes or squeegees.

Brand name soaps and detergents recommended for cleaning polycarbonate are:

• anti-freeze • benzene

▪ Fantastik

• brake fluid

▪ Formula 409

• carbon tetrachloride

▪ Hexcel F.O. 554

• cutting oils

▪ Joy

• gasoline

▪ Lysol

• lacquer thinner

▪ Mr. Clean

• toluene

▪ Neleco-Placer

• turpentine

▪ Pine-Sol

• xylene

RESISTANCE TO WATER Polycarbonate material has good resistance to water up to approximately 65°C (150°F). Above this temperature the effect of water is timetemperature related. This means the higher the water temperature, the shorter the time before the polycarbonate is adversely affected.

Exposing polycarbonate to repeated steam cleaning or high temperature pressure washing may result in crazing, a phenomenon that causes clouding of the surface. Crazing can ultimately result in a loss of physical strength and may precede a fracture.

▪ Top Job 3. Rinse the window thoroughly with lukewarm water.

4. Dry the window with a moist soft cloth, cellulose sponge or chamois to prevent water spotting.

5. To remove grease or oil, first rub lightly with a good grade of VM&P Naphtha or isopropyl alcohol followed by the same rinse, wash, rinse and dry procedure described in steps 1 to 4.

Refer to WINDOWS – CARE OF POLYCARBONATE WINDOWS – RESISTANCE TO CHEMICALS for a list of chemicals which should not come into contact with polycarbonate windows.

Lubrication and Maintenance

CAUTIONS

SIDE WINDOW SCREENS

• Do not use abusive cleaning procedures either by hand or pressure washing on polycarbonate windows.

• Do not use brushes, razor blades, scrapers, squeegees or other sharp tools on polycarbonate windows.

• Do not clean polycarbonate windows when the daytime temperature is high or in direct sunlight.

WINDOW SCREEN HAND KNOB

• Do not use abrasive or highly alkaline cleaners on polycarbonate windows.

• Do not use glass cleaners in either aerosol or non-aerosol containers to clean polycarbonate windows.

• Failure to follow these cleaning instructions will shorten the service life of polycarbonate and may cause visual hazing, loss of light transmission and delamination of the polycarbonate hard surface coating.

CONCEALING HAIRLINE SCRATCHES The appearance of scratches and minor abrasions on the surfaces of polycarbonate windows can be minimized by using a mild automotive polish such as:

855D-031

SIDE WINDOW SCREEN

The side window screens (if equipped) can be removed to clean the windows. Screens are provided for the personal protection of the operator and must be reinstalled immediately after cleaning the windows.

A hand knob is provided on both the inside and the outside. By unscrewing either (not both) of these knobs, the screen will be free to swing out on the hinges. Be aware the screen will swing outwards with considerable force, if the door is open.

• Johnson’s Paste Wax • Novus Plastic Polish #1 and #2 • Mirror Glaze Plastic Polish Be certain to clean the polycarbonate window as outlined prior to application of an automotive polish. Refer to WINDOWS – CARE OF POLYCARBONATE WINDOWS – CLEANING INSTRUCTIONS.

All hand knobs should be hand tightened only at all times.

3.105

Lubrication and Maintenance

Tigercat 855D/L855D Feller Buncher

GRAFFITI REMOVAL For removal of paints, marking pen inks, etc., the use of Butyl Cellosolve is generally effective. The use of masking tape, adhesive tape or lint removal tools works well for lifting off old weathered paints.

To remove labels, stickers, etc., the use of kerosene, VM&P Naphtha, or petroleum spirits is generally effective. When the solvent will not penetrate sticker material, apply heat (hair dryer) to soften the adhesive and promote removal.

Refer to WINDOWS – RESISTANCE TO CHEMICALS for a list of chemicals which should not be permitted to come into contact with polycarbonate windows.

FIRE PRECAUTIONS Polycarbonate window material will ignite when exposed to an ignition source in excess of 427°C (800°F). When working around polycarbonate windows, observe similar fire precautions to those in place for wood.

REMOVAL OF ANTI-CORROSION SPRAY (IF APPLICABLE) Some machines, particularly machines shipped outside North America, are shipped with an optional anti-corrosion spray to protect the machine from corrosion during shipment.

This anti-corrosion spray should be removed when the machine reaches its destination as it may cause debris to stick to the treated surfaces of the machine.

The anti-corrosion can be removed with a pressure washer, a sponge and soap.

3.106

Tigercat 855D/L855D Feller Buncher PROTECTING STEEL TRACKS

Lubrication and Maintenance Alternate turning directions.

If you're turning in the same direction, the undercarriage components on one side of the machine will wear at a different rate than those on the other side. To ensure even wear, pay attention to the way you're turning-and change directions whenever possible.

Make gradual turns instead of counter-rotations.

Steel tracks are designed to perform in tough underfoot conditions. Take these steps to maximize service life and reduce operating costs.

Start every shift with a clean undercarriage.

When mud and debris build up on the lower part of your machine, components wear at a faster rate.

Do not begin work until the undercarriage area is clean.

Inspect the undercarriage before you start working.

In addition to ensuring the undercarriage is clean, spend a couple of minutes on a visual inspection.

Check for loose bolts, leaky seals and abnormal wear patterns. When you spot potential problems early, you can often prevent them from turning into bigger issues that reduce component life significantly or cause expensive unscheduled downtime.

Counter-rotating accelerates wear on the tracks and other undercarriage components. Don't use that technique unless job conditions demand it. Instead, turn the machine gradually while slowly moving forward or reverse. Gradual turns minimize cuts, tears and excessive wear in the undercarriage. They also reduce damage to soft or sensitive work surfaces.

In the event a counter rotation is required some machine operators will carefully push the boom and attachment down against a suitable obstacle and lift the forward or rear sections of the track off the ground. The operator will then counter rotate the tracks while swinging the upper structure.

This will disengage most of the track length from the ground during the counter rotation resulting in less site damage and potentially less track wear.

This is a complex maneuver and should only be completed with fully trained and experienced operators working in stable ground conditions.

Don't spin the tracks.

Track spinning, reduces production, it increases fuel consumption, without a corresponding increase in productivity. And it accelerates undercarriage wear, so your costs escalate.

Grouser bars are especially prone to wear problems associated with track slippage.

Watch your speed.

There are times when a job requires higher speed operation, but the fact is, wear accelerates as speed increases. Links, rollers and idlers are particularly vulnerable. Keep them working longer by controlling your speed.

Avoid unnecessary reverse operation.

Operating in reverse-even at slow speedscompounds bushing and sprocket wear as the track tension loads are applied to the top side of the chain. So avoid an unproductive reverse operation.

Work up or down a slope whenever possible.

Working across a slope can shorten undercarriage component life, so try to structure the job with minimal cross-slope activity.

3.107

Lubrication and Maintenance

Tigercat 855D/L855D Feller Buncher

Watch transition areas.

Try to minimize travel over transition obstacles as this accelerates undercarriage wear. If you must go across a transition, position the machine 90° to the transition. Without ground support, the undercarriage is subjected to side stresses that can result in rapid, excessive wear.

Configuration refers to the way your machine is equipped and is therefore something you can control. To minimize undercarriage wear on steeltrack machines, use the narrowest track shoe possible that meets your flotation requirements. If you work in very sticky materials, consider using centre-punched track shoes to reduce material packing in the undercarriage area.

Other factors:

Application refers to the type of work you do.

Bunching, loading, grading, digging and trenching are a few examples. This factor is largely beyond your control, but generally speaking, the more you work in high horsepower, high-torque applications, the faster your undercarriage will wear.

Material type is another key contributor to undercarriage wear that is outside your control, the more abrasive the material, the more rapid the wear rate.

Terrain, a third uncontrollable factor, describes the contours and slopes at your job site. The more time you spend in rugged, sloped areas, the faster your undercarriage will wear out.

Maintenance discipline plays a big role in undercarriage component life. One of the most critical maintenance practices is track adjustment.

Tight track is the number-one "track killer." But whether your track is too loose or too tight, improper adjustment accelerates wear which can increase downtime and repair costs. Follow the manufacturer's recommendations for track adjustment, and perform the adjustment in the machine's working environment. A second important maintenance process is cleaning the undercarriage. To maximize wear life, remove mud and debris at the end of every shift, or more frequently if necessary.

Talk to the experts: Undercarriage components are expensive!

To get long life and maximum value from your investment, consult with a dealer or factory rep that really knows the undercarriage business.

Ask for advice on operating techniques. Explore relevant application, material and terrain issues.

Fine-tune your maintenance processes. Working together with an undercarriage expert, you can manage your equipment investment over the long term.

Assembly Torque The four-bolt port is simply a circular opening (flow passage) surrounded by four tapped holes in a certain pattern for acceptance of the flange clamping bolts. The flat surface of the port compresses the O-ring contained in the groove in the flange head when the clamp bolts are torqued. In some instances, the groove is in the port and not in the flange head. The bolts, through the clamp halves, clamp down the flange head onto the flat surface of the port compressing and trapping the O-ring in the groove and leaving no gap for it to extrude under pressure. The hydraulic pressure is thus sealed by the compressed O-ring as long as the bolts are tightened enough to maintain solid metal to metal contact between the flange head at the outside diameter of the O-ring and the top of the port.
