Introduction

Tigercat 855C/L855C Feller Buncher

THIS OPERATOR ENCLOSURE MEETS THE FOLLOWING STANDARDS: OREGON OSHA 437-007-0775:14a TIP-OVER PROTECTION STRUCTURES (TOPS) ISO 8082-2:2011 ROLL OVER PROTECTION STRUCTURES (ROPS) ISO 8084:1993 OPERATOR PROTECTION STRUCTURES (OPS) ISO 8083:1989 11 600J FALLING OBJECTS PROTECTION STRUCTURES (FOPS) ISO 2867:1994 SAE J1356: FEB 1988 OREGON OSHA 437-007-0775:14b,c AS 4988 2002 * MODIFICATIONS AND REPAIRS: The integrity of the ROPS, TOPS, FOPS, OPS 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 ROPS, TOPS, FOPS, OPS 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's 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 ROPS, TOPS, FOPS, OPS 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.

WARNING 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.

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

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

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

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

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

Some advice which 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.

• • •

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, always shut off engine before cleaning machine.

•

• •

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

•

Machine should be washed completely at every major service.

•

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

• •

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

Tigercat 855C/L855C Feller Buncher

Safety 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.

GENERAL SAFETY PRECAUTIONS continued Safety Hazards - Viton Seals 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 distance of 3 m (10 ft) between the machine or boom and any power line carrying up to 50,000 volts or less plus 10 mm (½ in.) for each additional 1,000 volts above the 50,000 volt level.

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

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.

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!!!

•

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.

•

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

•

Any cloths, residue and gloves must be safely discarded after use.

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 the OPERATOR'S MANUAL. 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 IDLE 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.

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

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.

Safety Hazards - Operating Maintain a charged fire extinguisher on the vehicle at all times and KNOW HOW TO USE IT.

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

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.

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

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

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.

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.

OPERATING SAFETY PRECAUTIONS continued MACHINE STABILITY AND TRACTION MACHINES WITHOUT LEVELER 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 felling head as low as possible to maintain a low centre of gravity.

•

Always be prepared to dump the load in case of an emergency.

Tigercat 855C/L855C Feller Buncher

OPERATING SAFETY PRECAUTIONS continued MACHINE STABILITY AND TRACTION 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.

20° 860C-009

Whenever possible work within the normal working range of the boom system as shown in FIG. 1. Note that in any boom position, both inside and outside of the normal operating range, there is a risk of instability and tipping. When it is necessary to work outside of the normal working range, be aware that the stability of the machine is reduced. The risk of tipping is increased while operating in the reduced stability working range.

16° 860C-010

NORMAL WORKING RANGE OF BOOM SYSTEM

FIG. 2 UNDERCARRIAGE LEVELING ANGLES 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. To minimize the risk of tipping observe the following:

UPHILL REDUCED STABILITY WORKING RANGE

•

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.

•

Always use the LOW speed setting for the track drives when on slopes.

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.

Safety

OPERATING SAFETY PRECAUTIONS continued •

NEVER travel across a STEEP slope or side hill.

•

Always carry any load on the uphill side of the machine.

Do not lift or move objects that exceed machine stability.

Always be prepared to release the load in case it causes the machine to tip.

Always 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.

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 aware that the machine is in its least stable position on a slope with the boom to the rear. Be particularly aware of machine stability when changing directions on, or travelling back down a slope.

As you gain experience, recognize that 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 that 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.

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.

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.

• Recognize that 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.

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.

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

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

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

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.

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

• Seek professional medical attention immediately.

ALWAYS 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.

•

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

•

Remove dirt and grease from grease fittings prior to greasing.

•

Tigercat 855C/L855C Feller Buncher LIGHTNING SAFETY

LIGHTNING SAFETY AWARENESS

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

WHAT IS A LIGHTNING STRIKE? 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.

•

Monitor daily weather forecasts

•

Observe local weather conditions

•

Alert all other members of the crew when a possible lightning threat develops.

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.

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.

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. Always follow step 4.

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 mi). 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 ft) within the soil around the strike point.

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 that they contain. Should lightning strike, the electrical current will travel through the wiring or plumbing into the ground.

When such a building is nearby, always seek shelter there first.

Thunder always 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.

1.26

Tigercat 855C/L855C Feller Buncher

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

LIGHTNING SAFETY AWARENESS continued

If you can, get inside.

1. Run to the nearest building, motor vehicle or fully enclosed ROPS equipment cab immediately. Being anywhere outside is not safe.

2. If inside a building:

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

•

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.

3. If inside a motor vehicle or fully enclosed ROPS equipment cab:

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.

•

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.

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 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.

•

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.

•

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

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.

Note that 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.

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

2. 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.

3. 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.

What to do if a co-worker has been struck by lightning.

If you are caught outside and have no where else to go.

1. Avoid wide-open areas where you project above the surrounding landscape.

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

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

2. Call your local emergency response telephone number immediately.

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

3. 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.

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

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

4. 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.

6. Avoid entering any small enclosures or shelters.

Safety 4. 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.

FIRE PREVENTION

When working in a forest environment, it is impossible to prevent combustible debris from collecting in tight corners of the machine. This debris, in itself, 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.

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.

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

1. Maintain a CHARGED fire extinguisher on the machine at all times and KNOW HOW TO USE IT. 2. 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 A/C CONDENSER, OIL COOLER AND RADIATOR in SECTION 2 of the OPERATOR’S MANUAL. 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.

1.29

5. 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 any equipment.

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

7. 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.

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

9. 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.

10. 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.

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

12. 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.

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 always 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. Refer to PRESSURIZED WATER SYSTEM MAINTENANCE in SECTION 3 of THIS MANUAL.

•

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.

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

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.

16. 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.

•

17. 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.

•

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

•

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

•

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

1.30

Ensure that 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 DETECTION SYSTEM in SECTION 2 of the OPERATOR’S MANUAL. Ensure that your fire suppression system** is charged and in working order. Refer to FIRE SUPPRESSION SYSTEM in SECTION 2 of the OPERATOR’S MANUAL. Ensure that you are familiar with the recommended procedures for fire contained in the emergency action plan of your company.

Safety WHAT TO DO WHEN A MACHINE FIRE OCCURS

FIRE PREVENTION continued •

•

•

•

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: 1. Workers assigned to fire fighting duties must be physically capable of performing them safely and effectively.

2. Workers designated to use fire fighting equipment as part of an emergency action plan must receive full and proper training from a qualified instructor.

3. 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.

4. 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.

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: 1. The fire is small and not rapidly spreading.

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

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

4. 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.

5. Be aware that engine coolant , diesel fuel or hydraulic hoses could fail during a fire.

If this happens, hot coolant, fuel or oil could possibly be ignited by the fire.

6. 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.

Safety

DRY CHEMICAL CLEANUP PROCEDURES

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

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.

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. Therefore when the break down procedure has been completed, follow this immediately with the neutralizing procedure as described in step 2

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.

1. 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.

2. 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.

To neutralize the acidic paste on large surfaces, spray or wash these areas with a mixture of three parts hot water to one 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.

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

STORED ENERGY

OTHER INSTRUCTIONS

The saw blade stores energy from the hydraulic motor during the times between tree cuts so that it can supply up to 1000 hp during a 1 sec tree cut. However this rotational energy, if misapplied can result in wood materials or other objects being thrown strongly enough to cause damage and to hurt people.

It is also understood and expected that all instructions contained in service and operator's manuals for use and maintenance of Tigercat disc saw heads and other disc saw heads installed on Tigercat machines will be followed.

THE DANGERS

BE AWARE OF THE HAZARDS

There are at least these means by which a rotating disc saw can cause harm by throwing:

It is important that users of machines with disc saw felling heads are aware of certain safety precautions that need to be taken. In this section some previously unknown, unexpected safety hazards are illustrated and explained . These should be studied before use of the machinery 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

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

It is understood and expected that logging organizations and operators will develop and practice additional rules that suit (for example) particular conditions of terrain, trees, soil and job requirements. The information given here 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 hence to assist in development of safe operating practices.

• 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 here.

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.

Figure 3 shows a typical commonly used saw housing plan where there is 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 throw. There are snouts on both sides of the mouth so that if pushed against the side of a felled tree or log the saw teeth will not contact the wood.

IF A SAW HEAD IS PUSHED AGAINST THE SIDE OF A FELLED TREE, SNOUTS PREVENT SAW TEETH FROM CONTACTING WOOD.

Figure 4 shows another commonly used plan. It has no blade guarding snouts so that the saw blade teeth do protrude ahead of the housing. This may be preferred over figures 3 and 5 for dexterity in tree getting.

In figure 5, there is 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 snout.

HOUSING TYPES CONTINUED In figure 6a and 6b there is an additional opening in the housing skirt. Openings in this location are sometimes provided for escape of wood chips produced by the saw teeth in the cut and being taken into the housing.

In figure 6c a guard has been added to the chip escape port so that tangential travel of chips and other material is intercepted as soon as it leaves the housing.

Each figure shows 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.

It is important that the operator familiarize himself with the blade rotation direction, the effectiveness of any snout on the in-going side and which direction any chip escape ports allow material to fly.

Using High-Speed Disc Saws Safely ASSESSING THE POTENTIAL DANGERS ON THE JOB SITE

COMMENTS AND INSTRUCTIONS

The extent of danger from high speed disc saws on the logging operation has to be assessed on the job site, depending on how much other work activity is in the area and whether the operator can do his 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.

RECOGNIZING THE DANGERS While it may appear that these illustrated danger areas can be visually recognized on the job by observing how far chips fly during a cut, that is only 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 Poor saw maintenance increases these dangers. Some designs that might allow fasteners to wear thin or fatigue and suddenly break, need thorough timely replacement procedures. It is important that the warning signs of missing saw tooth parts or the sounds of striking rocks be heeded and the operation adjusted to avoid danger.

DIRECTION OF THROW 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 angle of throw is pointed by boom geometry, 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.

COMMENTS AND INSTRUCTIONS CONTINUED HIGH ANGLE WRIST ROTATION ABILITY When a felling machine is equipped with a high speed disc saw head with a high angle wrist rotation ability it should be determined that the limits of the boom, stick, tilt, wrist, upper leveling and any other freedoms, do not permit a direct throw at the operators cab during normal operation, see figure 7a. It is probably essential that the housing have a long snout on the throw side and that if a chip escape port is used 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, refer to figure 2 and 7b. 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 especially constructed to prevent penetration by accidentally thrown objects.

Tigercat In this last case tests have shown that if the piece of wood is backed-up by a solid slippery surface; and if the feed in is very fast; and if the piece of wood is long enough; then the tangential movement is a dangerous spear-like throw.

COMMENTS AND INSTRUCTIONS CONTINUED THROWING LONG WOOD PIECES Dangers from throws of long wood pieces are illustrated in figures 8 to 11.

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

Figures 8 and 9 show two ways that this might happen in the woods if using the saw head of figure 4 (where the throw contact can be long). 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. A small log in a pile of other logs might also be propelled out with enough length of continued contact to reach near saw tip speed.

A SMALL LOG IN A PILE OF OTHER LOGS MIGHT ALSO BE PROPELLED OUT WITH ENOUGH LENGTH OF CONTINUED CONTACT WITH THE BLADE TO REACH NEAR SAW TIP SPEED.

COMMENTS AND INSTRUCTIONS CONTINUED Figure 10 shows how a head with snouts does not allow a long throw contact. Although tests show that a short contact length on a long log or tree butt does not result in a spear like throw, this action should nevertheless be avoided because abnormally large chips are sometimes produced and thrown.

FIGURE 10: FELLING HEAD HOUSING WITH SNOUTS DOES NOT ALLOW A LONG THROW CONTACT Figure 11 warns that 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 BLADE THROW GAP 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, see figure 12. Fallen sticks and debris or sticks and debris sliding across the saw blade can enter these gaps when the blade is rotating and be struck by the teeth and be tossed or thrown. Larger gaps and lower rotation speeds increase these dangers.

COMMENTS AND INSTRUCTIONS CONTINUED SAW HOUSING ENTRANCE AND EXIT SPACE 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 will allow most things inside to be thrown out, see figure 13. Its throw direction and angle must be respected. A long snout on the other side reduces this danger.

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. Tigercat is continuing to do design and testing of 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.

THE FOLLOWING ARE SOME SAW HEAD DON’TS THAT APPLY PARTICULARLY TO THROW PREVENTION: • 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 blade speed is low.

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

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

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

• Do not select and operate heads that throw rearward.

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

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

Press and hold this switch to sound the safety alert horn.

HIGH. NOTE: See also TRAVEL SPEED CONTROL earlier in this section.

Always use this horn prior to starting the engine and to alert other personnel in the area of your presence.

LOW: Placing the switch in the LOW position will provide the slowest travel speed but with increased torque or driving force.

12. CIGARETTE LIGHTER (24V) Cigar/Cigarette lighter (24V).

The DRIVE position will provide a faster travel speed range but with a lower driving force.

13. SAW - SWITCH This is a two position switch labelled ON/OFF. Use this switch to turn the saw ON. On Feller Buncher Machines equipped with the Shear Felling Head, this saw switch supplies power to the attachment’s control systems. A lockout button is incorporated into the switch to prevent the switch from being turned ON accidentally. To turn the switch ON, push and hold the lockout button UP and place the switch in the ON position.

It is recommended that during all harvesting functions and when travelling on slopes that the range switch be placed in the LOW position to maximize drive motor life. LOW position is indicated by a light on the Track LOW/DRIVE switch.

HIGH: When this switch is in the DRIVE position the travel speed (and torque) ranges of the drive system become infinitely variable and will automatically adjust to any point between the HIGH and LOW speed/torque set points, relative to the terrain or load conditions.

Place throttle in FULL position before turning attachment ON. NOTE: If the engine has been turned off or the pilot shut off system tripped (Front Door opened) with the saw switch left in the ON position, the attachment will not start up when the engine is restarted or the front door closed. In this case press the PILOT RESET button and turn the saw switch OFF and then ON.

It should be noted that the available torque when travelling at maximum speed is only half of that in LOW. The DRIVE position will provide a faster travel speed range but with a lower driving force.

However, when the machine encounters tougher terrain conditions, e.g. stumps, soft ground or slopes etc., the drive system will automatically adjust* to a slower travel speed/ higher torque range.

NOTE ALSO: On Harvester Model Machines and Shovel Loggers this saw switch supplies power to the attachment’s control systems.

NOTE ALSO: The function of this switch may vary depending on the attachment model used and method of installation. Verify all functions before operating this machine.

*This amount of adjustment can be anywhere from a slight reduction in speed all the way down to LOW, this will be dependent on the terrain conditions encountered.

NOTE: The operator should be aware that this automatic speed/torque range adjustment will cause the machine to gradually slow down over a period of one to two seconds, due in part to the infinitely variable displacement drive motors used. When travelling on relatively flat terrain it is not necessary to place the range switch in the LOW position .

15. COOLING FAN - SWITCH This is a three position switch, labelled CLEAN / AUTO / FULL ON. This switch along with an electronic fan control module, controls the operation of the hydraulic cross-flow fan.

AUTO POSITION - 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.

FULL ON (OVERRIDE) DOWN 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.

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.

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 idle. This is to ensure that sufficient air flow is available for the cab A/C even while the machine is still warming up.

Controls and operation

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

CLEAN - UP POSITION - 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 of the radiator.

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

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). Refer to COMPUTER ~ INFORMATION MESSAGES and COMPUTER ~ DIAGNOSTIC ~ ADJUST FUNCTION PARAMETERS in THIS SECTION. NOTE: If engine speed falls to 875 rpm or less the fan speed control is automatically overridden and fan speed defaults to the forward direction.

DISCHARGE OF THE 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.

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.

COMPONENT LOCATIONS

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.

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.

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.

If the proper height cannot be reached using one of the four height adjustment settings, it may be necessary to install the seat on a higher base.

RIDES TOO STIFF/SEAT TENDS TO PUSH OR THROW OPERATOR FORWARD 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 height adjustment lever to raise the seat.

Refer to HEIGHT ADJUSTMENT PROCEDURES.

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”. Refer to HEIGHT ADJUSTMENT and RIDE ADJUSTMENT PROCEDURES.

RIDES TOO SOFT OR BOTTOMS OUT AND PINCHES OPERATOR The air ride control valve has under pressurized 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. Refer to HEIGHT ADJUSTMENT PROCEDURES.

Alert engine fault message(s) will be displayed, alarm warning light will flash and alarm will sound when an alert engine fault message is received from the engine electronic control module.

Information messages give the operator information regarding an event or problem condition while the event or problem exists.

They provide the SPN code (suspect parameter number) and the FMI code (fault mode identifier) as well as a message describing the fault (when available).

Information messages have lowest priority and are used to give the operator information that is useful to the operator, but requires no action to prevent immediate or future damage to the machine

Alert engine fault codes are lower priority messages than critical level engine fault code messages. Alert messages can be hidden but action (service engine) is required to resolve the cause of the fault.

When an information message is displayed on the screen the message will either automatically disappear when the condition no longer exists or stay on the screen until the operator acknowledges the message.

An example of an alert engine fault message is shown above.

Information messages can be acknowledged by pressing the F2 button (OK). Acknowledged information messages are removed from the screen.

NOTE: Some less common engine fault codes will appear without a message describing the fault. Make a note of the SPN and FMI codes and contact service for more information.

The return oil entering the hydraulic tank passes through six replaceable filters mounted on filter heads beside the tank and three mesh type reusable strainers one on the end of each return tube in the reservoir.

PRESSURE GAUGE

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). Refer to HYDRAULIC TANK PRESSURIZATION INSTRUCTIONS in SECTION 3 of THIS MANUAL for details.

There is a bypass valve built into each filter head preset at 25 psi (1.7 bar), which will open in the event the elements become restricted. Before this valve is activated, a 20 psi (1.4 bar) filter restriction switch, located on one of the filter heads, will cause the Hydraulic Oil Filter Bypass icon on the computer display to illuminate red.

Note that the hydraulic oil filter bypass icon will be illuminated yellow when hydraulic oil temperature is low and the filter restriction switch is activated.

Note also that the hydraulic oil filter bypass icons are also used to indicate a charge filter (swing) restriction.

IMPORTANT

Contaminated hydraulic fluid can lead to premature failure of hydraulic components and costly repairs.

Filters must be replaced at the recommended time intervals, See SECTION 3 in THIS MANUAL. Use of filters other than genuine Tigercat replacement filters is not recommended.

FILTER RESTRICTION PRESSURE SWITCH The bypass valves built into each filter head, preset at 1.7 bar (25 psi) will open in the event the elements become restricted. Before these valves are activated, a 1.4 bar (20 psi) filter restriction pressure switch installed in the return manifold, will send a signal to the computer control system when an oil flow in excess of 1.4 bar (20 psi) is encountered at the return filters. This pressure switch closes and the hydraulic oil filter bypass icon displays RED on the MD3 computer. The master alarm and alarm light will sound and flash.

CASE DRAIN STRAINERS

860C-085

CASE DRAIN STRAINERS Two case drain strainer elements are located on the machine. One element is located in the pump compartment and services most pump case drains. The other strainer element is located under the main Linde valve in the valve compartment.

This element is dedicated to case returns from the attachment head. ONLY IN THE EVENT OF A PUMP OR MOTOR CATASTROPHIC FAILURE SHOULD THESE ELEMENTS BE SERVICED.

IMPORTANT! DO NOT use these warnings as a substitute for checking the oil level at regular intervals as per the SCHEDULED MAINTENANCE program in THIS SECTION. This information is assuming that operating conditions and running temperatures are NORMAL.

2

FILTER/STRAINER SERVICE NOTE: The filters should be checked/changed when the oil filter bypass icon displays RED on the MD3 computer. If the icon continues to display RED after the filters have been changed, the return strainers attached to the base of the return tubes in the hydraulic tank should be examined for possible obstruction.

HYDRAULIC OIL HEATER (OPTIONAL) This is a 120V, 2000W immersion heater (1) with one outlet plug (2).

IMPORTANT

NEVER PRE-FILL HYDRAULIC FILTERS

CAUTION Do not leave the heater plugged in for a prolonged period of time without the oil circulating. Localized high temperatures can damage hydraulic oil.

Tigercat generally 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 valves, pumps and motors. The cleanliness of hydraulic oil cannot be guaranteed unless it is always pre-filtered before use.

AIR CLEANER UNLOADER VALVE 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.

AIR INTAKE BOX

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.

855C-202

ENGINE AIR PRECLEANER 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 periodically to make sure that foreign materials have not plugged the intake area or the exhaust port area.

HOW IT WORKS: 1. Dirty air (1) enters the precleaner, which is clamped onto the engine air intake.

2. Specially designed vanes (2), curved and angled to precisely direct air flow, move the dirty air toward the stainless steel impeller (3).

3. The dynamically balanced, one piece impeller (3) (only moving part) creates a tornado inside the housing.

4. The centrifugal force of the tornado expels the heavier than air dirt particles (4), chaff, dust, snow, rain, etc., out the discharge louver 5. Cleaned air (5) enters the engine air cleaner intake pipe, and the filter element has only the very light particles to remove.

The hydraulic oil cooler/radiator/charge air cooler (CAC) is mounted at the rear of the upper frame, protected by a debris screen. The A/C condenser core is mounted at the rear of the cooling assembly. The hydraulically driven fan draws air through the screen, through the A/C condenser, the oil cooler/radiator/CAC cooling assembly.

OPEN ACCESS DOORS PIN STOP

The A/C condenser core and the oil cooler/ radiator/CAC cooling assembly should be checked every eight hours (every shift) for accumulation of twigs, leaves, pine needles and dust. All of the engine enclosure doors should also be kept clean.

PIN

REAR CLEAN-OUT DOOR

3. Swing the latch pin stop to the side, lift up the pin and open the clean-out door on the rear of upper frame 4. Slide the debris screen out over top of the cooling assembly.

CLEANING PROCEDURE: 1. Shut down the engine as per instructions in ENGINE STOPPING in THIS SECTION.

5. Remove two nuts and carefully swing open the A/C condenser (on hinges) to expose oil cooler/radiator/CAC cooling assembly and remove any accumulated debris.

Always follow proper engine shutdown procedures. The important benefits are: •

Extended life of engine, cooling and exhaust systems.

•

Reduced risk of post shutdown fires.

•

Interior of machine cools significantly reducing risks from touching hot surfaces.

CAUTION

2. Open the top (1) and left side (2) access doors.

Use compressed air for cleaning only when the machine is cold to avoid the risk of fire caused by debris being blown into contact with hot surfaces.

If using compressed air for cleaning, use at 2 bar (30 psi) or less.

Always use personal protective equipment (eye wear) to guard against flying debris.

6. When the units have been cleaned return all cooling components to their operating position.

2.76

Tigercat 855C/L855C Feller Buncher

Controls and operation Pay particular attention to cleaning in the corners of the cooler as these areas usually plug deeply.

Reversing the fan at least once per hour will help reduce the dust accumulation in the cooler cores, see COOLING FAN SWITCH, CLEAN POSITION earlier in this section to manually reverse fan or see ADJUST MENU/MACHINE PARAMETERS/ TIMED PURGE INTERVAL for resetting computer to change cooling fan purge interval to program the fan to reverse every hour automatically.

For more information on fire prevention refer to FIRE PREVENTION in SECTION 1 of THIS MANUAL. If an oil leak occurs in this area it should be thoroughly power-washed with a mild soap to ensure that all of the oil is removed. The presence of oil causes dust and dirt to cling to surfaces which will impair the reversible fan’s ability to remove dust and dirt particles.

CAUTION Avoid the risk of fire caused by debris accumulating on surfaces that may become hot during machine operation.

Always use care when cleaning to ensure that debris removed from one area of the machine does not accumulate on other areas of the machine.

NOTE: The cooling assembly must be checked daily and may have to be thoroughly cleaned on a daily, weekly or monthly basis, depending on operating conditions. Use personal protective equipment (eye wear) to guard against flying debris. Use compressed air for cleaning only when the machine is cold to avoid the risk of fire caused by debris contacting hot surfaces. Care must be taken not to set the pressure too high otherwise damage to the components could result.

Controls and operation

Tigercat 855C/L855C Feller Buncher OPERATING TIPS WITH LOAD SENSING

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

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.

Place the track switch in the LOW or DRIVE position.

When in LOW the machine moves slower but with increased drive force. All harvesting should be done in LOW. When in DRIVE the machine moves faster but with less drive force. Travelling over longer distances (and not harvesting) 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.

Load sensing systems respond to rough operation by amplifying these movements. If you find the boom is jerky or always 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.

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 idle position.

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

FELLING HEAD OPERATING INSTRUCTIONS AND SAFETY PRECAUTIONS

SPECIAL OPERATING INSTRUCTIONS FOR ER BOOM SYSTEM (OPTIONAL) NORMAL HORIZONTAL REACH MOTION PERFORMANCE CAN BE EXPECTED IN THIS AREA

1. All tree harvesting should be carried out in LOW driving range. Refer to TRACK, LOW/ DRIVE SWITCH in THIS SECTION.

OPERATING THE MAIN 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

2. See appendix to SECTION 1 - USING HIGH SPEED DISC SAWS SAFELY. 3. See ORIGINAL MANUFACTURER’S FELLING HEAD MANUAL for proper operating and maintenance instructions.

NOTE: Refer to specific MANUFACTURER’S ATTACHMENT MANUAL if machine is equipped with a shear head or harvesting head for additional operating and safety precautions.

845C-008

HORIZONTAL REACH MOTION CHARACTERISTICS 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.

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.

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.

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.

Refer to the next section for detailed information regarding inspection and maintenance of polycarbonate windows.

INSPECTION AND MAINTENANCE

RESISTANCE TO CHEMICALS 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.

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 • anti-freeze • benzene • brake fluid • carbon tetrachloride • cutting oils • gasoline • lacquer thinner • toluene • turpentine • 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 that the higher the water temperature, the shorter the time before the polycarbonate is adversely affected.

Exposing polycarbonate to repeated steam cleanings 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.

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

• Inspect all windows daily and immediately after any impacts.

• 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 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.

CLEANING INSTRUCTIONS

CAUTIONS

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.

•

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.

•

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.

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: • Fantastik • Formula 409 • Hexcel F.O. 554 • Joy • Lysol • Mr. Clean • Neleco-Placer • Pine-Sol • Top Job

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:

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.

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 CLEANING INSTRUCTIONS.

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

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.

WINDOW SCREEN HAND KNOB

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

860C-396

SIDE WINDOW SCREEN

SIDE WINDOW SCREENS 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.

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.

A handknob 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 that the screen will swing outwards with considerable force, if the door is open.

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.

All handles should be hand tight only at all times.

This anti-corrosion spray should be removed when the machine reaches it’s destination as is 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.

TIGERCAT OIL ANALYSIS PROGRAM Using the Tigercat Advanced Oil 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 oil 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 that 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 oil 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 Oil Analysis Program for all major machine components including Engines, Hydraulic Circuits, Axles, Final Drives, Gearboxes, etc.

TIGERCAT OIL SAMPLING PROGRAM OIL SAMPLE COLLECTION PROCEDURES

HYDRAULIC SAMPLE VALVE

Fill out the Sample Information Form (SIF) completely and accurately. When taking multiple oil samples, fill out all of the required SIF`s in their entirety, prior to taking any oil samples. Then, immediately package each completed SIF together with the matching oil 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 oil samples.

Incorrectly identified samples could result in a false warning alarm.

H855C-31

Hydraulic Oil Samples:

The accuracy of the lab analysis results is very dependent on the quality of the oil sample taken. Collection of clean oil samples that are representative of the main body of oil 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 follow-up samples should be consistently taken from the same location using the same techniques as all previous samples.

•

Ensure that all sample valves and drain plugs are clean and free of debris.

•

Remove the sample bottle cap only when ready to take the sample. Keep the cap clean – DO NOT put it in your pocket or let it get contaminated in any way.

•

DO NOT allow any airborne dirt, etc. to enter the sample bottle.

•

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

HYDRAULIC OIL

•

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.

•

To obtain a representative oil sample, sample valves must be purged before the actual oil sample is taken. Drain a minimum of three or four ounces of oil into a separate container and discard this oil using approved recycling methods.

•

Replace the dust cover on the sample valve immediately after taking the oil sample and sealing the sample bottle.

Gearbox Samples:

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.

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

3.6

•

These samples can be taken during the oil change process.

•

To obtain a representative oil sample, ensure the oil is warm and has not settled very long (within 30 minutes of shutdown).

•

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

•

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.

Lubrication and Maintenance

GENERAL 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.

Drain dirty oil while still warm.

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.

Do not exceed recommended fluid levels.

Always have a fire extinguisher at hand.

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.

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

SCHEDULED MAINTENANCE • ‡ Cylinders; hoist, stick & tilt; Conventional Boom; 8-fittings - purge ER Boom System; 10-fittings - purge

FREQUENTLY:

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

• Check for debris, snow and ice buildup on emergency exits and remove accumulation immediately.

• ER Boom system: Periodically, the main 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.

‡ Lubricating cylinder pins and boom joints: 1. Ensure machine is on level ground.

2. Fully retract telescopic stick (if equipped).

3. Lay attachment on ground.

4. Force tip of stick boom onto support.

5. While in this position lubricate all cylinder retaining pins and boom joints.

NOTE: This procedure will allow grease to flow to the normally "loaded side" of the pin/bearing surfaces.

EVERY 8 HOURS:

PARKING BOOM

Clean: • Oil cooler, engine radiator and enclosure screens.

• Remove potentially damaging limbs or sticks.

• Perform frequently maintenance And in addition: • Check engine coolant level.

• Check engine oil level.

• Drain water from fuel/water separator.

VENTING AIR FROM HYDRAULIC SYSTEM

VENT AIR FROM FITTING

• Check ALL air intake tubing, rubber couplings and band clamps for signs of wear and leakage • Replace hydraulic tank breather.

• Drain and refill hydraulic oil tank with recommended hydraulic oil. Refer to APPROVED HYDRAULIC OILS in THIS SECTION Check to ensure that 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 COMPUTER CONTROL SYSTEM ~ ALTERNATE MENUS~MACHINE SERVICE - HYDRAULIC OIL in SECTION 2 of the OPERATOR'S MANUAL 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: When refilling the hydraulic system, vent pumps, motors and valves of air by opening a plug or hose fitting located near or on top of the pumps, motors and valves until oil free of air is seen flowing out of the plug or hose fitting. Failure to vent air from the hydraulic system could cause serious damage to hydraulic components. Tighten plugs or fittings and clean up any spilled oil when completed.

Lubrication and Maintenance

SCHEDULED MAINTENANCE 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.

Before attempting to disconnect hydraulic hoses or perform work on the boom system, ensure that:STICK CYLINDERS FULLY EXTENDED

NOTE: Check all hydraulic system components especially cooling fan for proper operation after hydraulic oil has been replaced.

HEAD FLAT ON GROUND

ER BOOM SYSTEM

860C-001

FIG. 1 - ER BOOM SYSTEM

WARNING HOIST CYLINDERS FULLY RETRACTED

This machine may be 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:

TIP OF STICK BOOM FULLY SUPPORTED 860C-002

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 that 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.

FIG. 2 - ER BOOM SYSTEM

(a) The machine is parked on level ground with the head laying flat on the ground. (b) The stick cylinders are fully extended (FIG. 1) or the hoist cylinders fully retracted (FIG. 2). (c) The tip of the stick boom is supported.

For additional safety precautions refer to ER BOOM SYSTEM PRECAUTIONS in SECTION 1 of THIS MANUAL. ALSO 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 that there is sufficient overhead clearance for the attachment to rise before making any adjustments.

FILTERS - REMOVE AND REPLACE

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.

IMPORTANT! Failure to service and replace filters at the proper intervals specified in the manufacturer's manuals, could cause damage to the machine and result in the product warranty becoming NULL and VOID. Check Tigercat parts catalog for replacement filters.

IMPORTANT! Refer to the appropriate engine manufacturer's operation and maintenance manual for correct procedures and time intervals when servicing the engine oil and fuel filters. Read and understand the SAFETY section in each of these manuals.

FUEL FILTER/ WATER SEPARATOR FUEL FILTER

Tier III engines typically use filters with a very fine micron rating. 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 that the fuel/water separator 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.

To prolong the operating life of the fuel filter, ensure that the fuel supply storage tank is clean and free of water and that the fuel is pre-filtered prior to adding it to the machine.

WARNING Do not pre-fill engine fuel filters used on Cummins QSB6.7 engines.

HYDRAULIC FILTER SERVICING GUIDELINES IMPORTANT! NEVER PRE-FILL HYDRAULIC FILTERS

Tigercat generally 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 valves, pumps and motors. The cleanliness of hydraulic oil cannot be guaranteed unless it is always pre-filtered before use.

Contaminated hydraulic fluid can lead to premature failure of hydraulic components and costly repairs. Filters must be replaced at the recommended time intervals, Refer to SCHEDULED MAINTENANCE in THIS SECTION. Use of hydraulic oil filters other than the Tigercat brand could lead to severe wear and rapid failure of hydraulic system components.

WARNING

WARNING, 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.

•

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

•

DO NOT begin service work until the surface or system temperature has cooled down to below 38°C (100°F).

Lubrication and Maintenance HYDRAULIC TANK PRESSURIZATION INSTRUCTIONS. IMPORTANT! PRESSURIZED HYDRAULIC TANK. 34.5 kPa (5 psi) MAXIMUM. Before servicing hydraulic system, release air pressure from tank using air vent valve.

AIR VENT VALVE HANDLE (SHOWN IN UP POSITION) UP = CLOSED DOWN = OPEN

PRESSURE GAUGE 5 psi MAX (34.5 kPa)

SCHRADER VALVE ADD 34.5 kPa (5 psi) AIR PRESSURE TO PRESSURIZE TANK AFTER SERVICE IS COMPLETED

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.

Releasing hydraulic tank pressure in the event of a hose breakage may reduce oil loss.

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).

CHECK AIR INTAKE DAILY

860C-224

The air intake should be checked daily to make sure that foreign materials have not plugged the air intake area.

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

Refer to CLEANING THE AIR INTAKE PRE-CLEANER SECTION OF THE AIR CLEANER in THIS SECTION. In addition to the LUBRICATION AND MAINTENANCE SCHEDULE outlined in THIS SECTION, the following instructions should also be noted:

OVER SERVICING Filters 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.

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

IMPROPER SERVICING 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 safety filter are removed for replacement. The safety filterdoes reduce this risk but it should also be replaced at every third primary element change.

IMPORTANT STEPS TO FOLLOW WHEN CHANGING AIR FILTERS

6. Check your old filter for foreign material on sealing surfaces that is causing leakage.

NOTE: Filters 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.

7. Inspect the new filter(s) before installing.

Visually check for cuts, tears or indentations on the sealing surfaces before installation. If any damage is visible, do not install.

8. Replace safety filter (if replacing).

Insert the safety filter tab into the positioning slot before pushing the filter in place. Using the plastic handle on the safety filter, slide the filter at an angle into the outlet side and push in place until the filter seats firmly and evenly within the housing.

HOW IT WORKS: 1. Dirty air (1) enters the precleaner, which is clamped onto the engine air intake.

2. Specially designed vanes (2), curved and angled to precisely direct air flow, move the dirty air toward the stainless steel impeller (3).

3. The dynamically balanced, one piece impeller (3) (only moving part) creates a tornado inside the housing.

4. The centrifugal force of the tornado expels the heavier than air dirt particles (4), chaff, dust, snow, rain, etc., out the discharge louver 5. Cleaned air (5) enters the engine air cleaner intake pipe, and the filter element has only the very light particles to remove.

UNLOADER VALVE 860C-405

AIR CLEANER UNLOADER VALVE 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.

AIR FILTER ELEMENTS

AIR CLEANER 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 that 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:

845C-070

The most common and most damaging air intake servicing problems are:

PRECLEANER OPERATION

HOW IT WORKS: 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. Strakes along the interior surface move heavier-than air debris towards the ejection slot

OVER SERVICING 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.

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 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.

IMPROPER SERVICING 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.

Lubrication and Maintenance

IMPORTANT STEPS TO FOLLOW WHEN CHANGING FILTER ELEMENTS 1. Release the cover latch gently to reduce the amount of dust dislodged.

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

3. Always clean the sealing surface of the outlet tube before inserting a new filter element.

4. Always clean the inside of the outlet tube.

5. 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.

6. Inspect the new filter for damage.

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

8. 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.

TRACK OPERATION AND WEAR PREVENTION

Alternate turning directions.

If you're always 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.

PROTECTING STEEL TRACKS 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.

Make gradual turns instead of counterrotations.

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 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 frame. 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 by fully trained and experienced operators working in stable ground conditions.

Inspect the undercarriage before you start working.

In addition to ensuring that 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.

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 speeds, compounds 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.

3.46

Tigercat 855C/L855C Feller Buncher

Lubrication and Maintenance

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.

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.

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

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 always 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 4-Bolt Split Flange consists of four main components: • A body (flange head) • An O-ring • One “captive” or two “split” flange clamps

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.

• Four bolts and washers

WASHERS BOLTS FLANGE CLAMP

Flange Port Assembly

FLANGE HEAD

The steps to properly assemble the flange port clamping bolts are: 1. Make sure sealing surfaces are free of burrs, nicks, scratches or any foreign particles.

2. Lubricate the O-ring.

3. Position flange and clamp halves.

4. Place lock washers on bolts and insert through clamp halves.

5. Hand tighten bolts.

6. Torque bolts in diagonal sequence (see Fig. T9) in small increments to the appropriate torque level listed in Table T6 or Table T7 on this page.
