Introduction

An Operator's manual, Service manual and a Parts catalog are made available by Tigercat to assist the dealer, customer and operator in becoming familiar with the features of the H855D/LH855D Harvesters.

Serial numbers: H855D 85532501 TO 85533000 LH855D 85582001 TO 85583000 NOTE: The 4th digit in the machine serial number indicates the machine model type. For example, 3 = Harvester and 8 = Leveling Harvester. For simplicity throughout this manual the 4th digit has been replaced with an asterisk to indicate that both types of machine models are affected, ie: 855*2001 TO 855*3000.

The H855D/LH855D Harvesters are designed for harvesting trees, at-the-stump processing or roadside processing applications in thinning, selective felling and clear felling applications in plantations and natural stands.

The operator's manual will assist the operator with the techniques of proper and safe operation of the H855D/LH855D Harvesters. There is also important information regarding the safe operation of the attachment. The service manual contains safety and servicing procedures and a preventive maintenance schedule to ensure optimum machine performance.

Section 1 in both the operator's manual and the service manual contains safety information that must be followed. As well, throughout the rest of the manuals, DANGER, WARNING and CAUTION notices are displayed where necessary, drawing attention to possible hazards when performing certain procedures.

Only trained personnel should be allowed to operate or work on the machine.

The information contained in this manual is current at time of printing. Improvements to the machine are on-going and may not be covered, therefore in these cases contact your Tigercat dealer for the appropriate information.

The phrase “and up” appearing in this manual after the serial number implies that the related information is current for any machine serial number HIGHER than the serial number preceding the “and up”.

Introduction

Tigercat H855D/LH855D Harvester

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.

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

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

Some advice which should be observed:

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.

•

Oils used in this machine may be hot enough to cause serious burns.

•

Avoid contact with oil, particularly heated oil.

•

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

•

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

•

Do not put oily rags in your pockets.

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

•

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

1.8

Tigercat H855D/LH855D Harvester

Safety

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).

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.

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

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 (0.5 in) for each additional 1,000 volts above the 50,000 volt level.

The following procedures are recommended when inspecting equipment that has been subjected to high temperatures such as fire: •

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.

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 soiled rags 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.

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.

Safety Hazards – Operating Maintain a charged fire extinguisher on the vehicle at all times and know how to use it.

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

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

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

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

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

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.

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.

MACHINE STABILITY AND TRACTION – MACHINES WITHOUT LEVELER

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

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

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

Never travel across a steep slope or side hill: •

As a load is added to the harvesting head the handling and the stability of the machine will change.

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

•

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

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

•

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

•

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

Secure loose items in the cab.

Always rest the harvesting head on the ground when operation is stopped, regardless if the engine is running or shut off.

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

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

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

Safety

Tigercat H855D/LH855D Harvester

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°

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

860C-009

NOTE: 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° NORMAL WORKING RANGE OF BOOM SYSTEM

860C-010

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 harvesting head 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.

860C-030

FIG. 2 – LEVELING ANGLES

FIG. 1 - WORKING RANGES

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

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.

1.14

Tigercat H855D/LH855D Harvester •

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

•

As you gain experience, recognize 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 if conditions are beyond your ability level.

Safety

Tigercat H855D/LH855D Harvester Working with the harvesting head in close to the machine:

HARVESTING HEAD CONTACT WITH CAB The boom of this machine is designed to enable the harvesting head to be tucked in close to the operator’s cab. This ability maximizes the maneuverability of the harvesting head to work around standing trees and while thinning in dense stands. See both the upper and lower images in FIG. 1.

•

Increases operator visibility, permitting better placement of the head on the tree and improving awareness of saw bar location and penetration, tree species and areas of rot, splits and crooks.

•

Reduces the potential for damage to both the standing trees and the harvesting head and stick boom components.

•

Improves the stability of a machine working on uneven ground as the weight of the boom, head and tree need not be extended as far out in front of the machine.

•

Broadens the working area that can be reached by the boom and thereby lessens the need to reposition the machine as frequently during harvesting operations.

If you don't have an exhaust pipe extension, either work outside, or open the shop doors.

Always install support braces in the leveling mechanism while performing service and maintenance tasks. This area is a crush zone.

Keep clear to avoid personal injury or death.

Dispose of fluids properly.

Do not pour fluids into the ground, stream, pond, or lake.

Before draining any fluids, know the proper way to dispose of them.

Read, understand, and follow all operating safety precautions specified by harvesting head manufacturer.

FLUID INJECTION INJURY

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

WARNING

When searching for possible fluid leaks:

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

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.

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.

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.

•

Never search for leaks with your bare hands.

Always wear thick protective gloves.

•

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.

•

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

In the event of any suspected fluid injection injury:

•

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.

•

Report the injury to your supervisor immediately.

•

•

Seek professional medical attention immediately.

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.

Safety

GREASE INJECTION INJURY WHEN USING PNEUMATIC GREASE GUNS

Prior to using a high pressure pneumatic grease gun perform the following:

Pneumatic grease guns can deliver grease at pressures from 17 – 400 bar (246 – 5801 psi).

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

•

All operators of high pressure pneumatic grease guns must be trained in the hazards of its operations and the treatment for such injuries.

Always get professional medical treatment immediately after any type of injection injury.

•

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

•

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

•

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

•

Make sure protective shrouds are installed on all grease gun nozzles as safety devices.

•

Remove dirt and grease from grease fittings prior to greasing.

•

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

•

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

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.

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?

•

Monitor daily weather forecasts

•

Observe local weather conditions

•

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

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.

2. Do not start or continue any work that cannot be stopped immediately, when a storm moves nearby.

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.

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.

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.

1.30

Tigercat H855D/LH855D Harvester

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

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.

•

Do not 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:

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

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

4. 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.

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

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

7. 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.

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.

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

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.

1.31

Safety

Tigercat H855D/LH855D Harvester What to do if you feel your skin tingling, your hair stands on end, light metal objects vibrate or you hear a crackling sound.

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.

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

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

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

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.

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

2. Call your local emergency response telephone number immediately.

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

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.

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

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

6. Avoid entering any small enclosures or shelters.

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.

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

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

To further increase your awareness about lightning safety, see the following web sites.

National Weather Service Lightning Safety http://www.lightningsafety.noaa.gov

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

National Lightning Safety Institute http://www.lightningsafety.com

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

11. Do not use the telephone except for emergencies.

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 may cause a fire and 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.

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.

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 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.

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) 11. Park the machine at least 15 m (50 ft) away at the completion of each work shift or more from other equipment at the end of each shift. frequently when working in logging conditions 12. Never leave the machine parked with the where large amounts of combustible forest boom and harvesting head suspended off debris are present. Visual inspection after the ground. Should their supporting hydraulic blow off to ensure thorough cleanliness hoses burn through during a fire, pressurized is vital. Engine exhaust systems provide hydraulic oil may be injected into the fire and numerous small pockets where saw dust, the boom and harvesting head will fall rapidly small wood chips and other flammable forest to the ground. debris can gather. Even small accumulations close to hot exhaust components can ignite and smoulder. If dislodged this smouldering debris can fall into other areas of the machine and thereby spread a fire.

1.33

Safety

Tigercat H855D/LH855D Harvester

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

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

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.

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

WHAT TO DO TO PREPARE FOR A MACHINE FIRE: 1. Prevent the fire from happening in the first place by ensuring that all machine systems are frequently inspected and always well maintained.

2. Make sure 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.

3. Make sure any pressurized water systems on the machine (if applicable) are charged and in working order. Refer to PRESSURIZED HYDRAULIC TANK in SECTION 3 of THIS MANUAL. 4. Make sure 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.

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.

5. 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.

1.34

Tigercat H855D/LH855D Harvester

Safety WHAT TO DO WHEN A MACHINE FIRE OCCURS:

6. Make sure 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.

1. If operating the machine when a fire occurs:

7. Make sure your fire detection system* is in working order. Refer to FIRE SUPPRESSION SYSTEM in SECTION 2 of the OPERATOR’S MANUAL. 8. 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. 9. Make sure you are familiar with the recommended procedures for fire contained in the emergency action plan of your company.

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

•

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

•

Lower all working attachments to the ground.

•

Shut the engine off.

•

Activate the fire suppression system**.

•

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

•

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

•

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.

•

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

2. Before deciding to fight the fire, be certain that:

•

•

•

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

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

11. Make sure 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.

12. Make sure 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.

1.35

•

The fire is small and not rapidly spreading.

•

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

•

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

•

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.

•

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.

•

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.

Tigercat H855D/LH855D Harvester

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.

Make sure 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: 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.

13. SWING BRAKE – SWITCH

14 COOLING FAN – SWITCH

This is a two position switch labelled ON/OFF.

This is a three position switch, labelled AUTO CLEAN / AUTO / FULL ON. This switch along with an electronic fan control module, controls the operation of the hydraulic fan.

CAUTION • Turning ON the swing brake while the boom is moving can damage the gearbox.

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.

• NEVER operate the tracks with the swing brake ON as boom contact with the ground will damage the swing gearbox.

Placing this switch in the ON position will apply the swing brake and prevent the upper structure from turning. The swing brake is a spring apply, hydraulic release, multi-disc brake. The brake is also engaged whenever the pilot system is shut off. As a safety precaution, the brake should always be applied with this switch when leaving the cab.

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.

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 2.18

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.

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

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.

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

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

2. De-energizing pilot circuit 3. Opening front door.

4. Shutting off engine.

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.

NOTE: When the ignition is turned off and then the machine is restarted the ER function will be ON (the default is ER ON).

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.

To turn the ER function OFF press the switch momentarily.

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

ER MODE - CURRENTLY OFF

The computer monitor will sound an alarm whenever the ER is turned ON or OFF and whenever the pilot switch is reset.

The computer will display the following: ER MODE - CURRENTLY ON or Press the F1 button on the front of the computer display to turn the alarm OFF and acknowledge the change to ER function.

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

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

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

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.

10A (FSS) FUSE

Each circuit on the machine is further protected against current overload by individual circuit fuses. The circuit fuses on the Fuse, Relay and Electrical Panel in Cab protect the cab electrical components.

The fuses in the Fuse and Relay Rear Panel protect the circuits for the work lights, engine ECU, engine enclosure power roof and many other machine operating circuits. Refer to the label on the previous page for specific fuse designation and location.

BOOSTER JUMPER PLUG

A 60 A fuse located in the battery compartment provides unswitched power for dome lights and service lights.

860C-225A

A 10 A in-line fuse protects the fire suppression system when a fire suppression system is installed. This fuse is located in the fire suppression power lead from the battery.

If a fuse “blows” it should be replaced with a fuse of the same amperage rating. If the fuse “blows” again, the circuit in question must be inspected for possible short circuit.

BATTERY BOOSTER JUMPER PLUG A battery booster jumper plug is located in the battery compartment. This jumper connector is used in conjunction with jumper cables with matching ends. Cables with matching ends are available through your Tigercat Dealer Parts Department.

PROBLEMS AND CORRECTIVE ACTION

SEAT TOO HIGH/SEAT TOO LOW There are several things which can cause improper seat height. Refer to Refer to SEAT ADJUSTMENTS in THIS SECTION and adjust seat to the desired position. 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 Refer to SEAT ADJUSTMENTS in THIS SECTION.

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 SEAT ADJUSTMENTS in THIS SECTION.

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 SEAT ADJUSTMENTS in THIS SECTION.

Diesel exhaust fluid (DEF) is an aqueous urea solution with 32.5% high purity urea and 67.5% deionized water. Note that DEF may also be referred to as AUS32 or AdBlue. All DEF must be American Petroleum Institute (API) Certified DEF or meet ISO 22241 specifications.

DEF is used by the Selective Catalytic Reduction (SCR) after treatment system to lower the concentration of nitrogen oxides from the diesel engine exhaust of this vehicle.

WARNING

DEF TANK

Use only diesel exhaust fluid (DEF) which meets ISO 22241 specifications. NEVER fill the DEF tank with any other fluid.

DEF fluid is injected into the exhaust gas stream during normal operation of the Selective Catalytic Reduction (SCR) after treatment system.

Use of other fluids may cause component damage, or a fire risk which could result in death or serious injury.

The DEF tank is located inside the left hand access compartment door in the left rear corner of the machine. The DEF tank fill cap can be accessed through this door. The DEF tank fill point is equipped with a filter to prevent contaminants from entering the tank.

DEF tank capacity is 80 L (21 US gal). Do not overfill tank. This tank is equipped with an expansion capacity of 7% required to allow for the expansion of DEF in cold temperature conditions.

DEF freezes at -11°C (12°F).

A DEF level indicator is shown on the main menu of the computer display, below the fuel gauge.

When DEF levels are low information messages and warnings will be shown on the computer display. Note that extremely low DEF levels may result in derating of engine performance to meet emission standard requirements. Action to correct DEF levels should be taken immediately to avoid affecting engine performance. Refer also to COMPUTER – MESSAGES in THIS SECTION. The DEF tank and DEF supply lines are heated when temperatures are low, the system will thaw DEF within 30 minutes of engine start for proper operation of the SCR after treatment system.

Note also that whenever the engine is stopped all DEF is pumped back to tank before the engine power system is turned off. This process takes approximately 90 seconds. Refer to DIESEL OXIDATION CATALYST/SELECTIVE CATALYTIC REDUCTION SYSTEM in THIS SECTION.

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

When a problem with DEF quality is detected information messages and warnings will be shown on the computer display. DEF quality problems may result in derating of engine performance to meet emission standard requirements. Action to correct DEF quality problems should be taken immediately to avoid affecting engine performance and damage to SCR after treatment system components.

Controls and Operation

STOPPING ENGINE

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

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

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

Always follow this engine shut down procedure.

The important benefits are: •

Extended life of engine, cooling and exhaust systems.

•

Reduced risk of post shutdown fires.

•

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

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

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

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

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

5. Open power roof Full ON

and place fan switch in

position.

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

7. Place fan switch in AUTO position.

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

NOTE: that whenever the engine is stopped all DEF solution is pumped back to tank before the engine power system is turned off.

This process takes approximately 90 seconds.

Refer to DIESEL OXIDATION CATALYST/ SELECTIVE CATALYTIC REDUCTION SYSTEM in SECTION 3 for more information.

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

2.109

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

Place the track switch in the LOW or DRIVE position.

When in LOW the machine moves slower but with increased drive force. All 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.

For a more detailed description of drive range refer to CAB CONTROLS – TRACK DRIVE SPEED CONTROL 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.

Tigercat H855D/LH855D Harvester OPERATING TIPS WITH LOAD SENSING When using the controls on a load sensing system be aware of what the load sensing system is trying to do for you. If you move the lever or pedal 20% of its total angle, the system will provide whatever pressure it takes (up to its maximum capacity if needed) to meet this speed requirement. If you move the lever past the point needed in an attempt to speed up the boom movement, you will only overshoot the speed you wanted. Relax and try to use the least amount of lever action you can.

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

Refer to HYDRAULIC SYSTEM OPERATION – MARGIN PRESSURE, SET in SECTION 4 of the SERVICE MANUAL Refer to the appropriate sections of the SERVICE MANUAL, BOOM, SWING or TRACK DRIVE to set the flow (function speed) rates.

Tigercat H855D/LH855D Harvester ATTACHMENT OPERATING INSTRUCTIONS AND SAFETY PRECAUTIONS

Controls and Operation SPECIAL OPERATING INSTRUCTIONS FOR ER BOOM SYSTEM

1. All tree harvesting should be carried out in LOW driving range. Refer to CAB CONTROLS – TRACK DRIVE SPEED CONTROL in THIS SECTION.

NORMAL HORIZONTAL REACH MOTION PERFORMANCE CAN BE EXPECTED IN THIS AREA

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. Refer to HARVESTING HEAD - GENERAL SAFETY in SECTION 1 of THIS MANUAL. 3. Read and understand the operating and safety instructions found in the MANUFACTURER’S MANUAL for the harvesting head installed on this machine.

845C-017

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.

CARE OF THE MACHINE

CARE OF POLYCARBONATE WINDOWS IN CAB

1. Ensure that all fluid levels are always at the proper level. Refer to SCHEDULED MAINTENANCE in SECTION 3 of THIS MANUAL.

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.

2. Lubricate all grease points at the required intervals as specified in the SCHEDULED MAINTENANCE in SECTION 3 of THIS MANUAL.

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.

3. Follow proper procedure for cleaning windows described in this section.

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

4. Close and secure all doors and access panels before running the machine.

5. Ensure that the cab emergency exits are in working order by following the EMERGENCY EXITS guide in this section.

6. Do not allow branches, twigs, leaves or pine needles to build up around radiator intake doors or anywhere else on the machine.

Clean as operating conditions warrant, but all debris must be removed from the machine interior at least once a day.

7. Do not apply load to a cold engine.

8. Always harvest trees in LOW driving range.

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.

9. Never park machine with head raised off the ground. Be sure that the head is resting on the ground before servicing or parking the machine. Refer to PARKING BOOM in SECTION 1 of THIS MANUAL for complete instructions.

10. SAFETY FIRST! Follow all safety rules and regulations as outlined in SECTION 1 of THIS MANUAL. IMPORTANT !

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

2.112

Tigercat H855D/LH855D Harvester INSPECTION AND MAINTENANCE 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.

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

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.

• •

• •

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 90 – 120 mL (3 – 4 oz) 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:

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.

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 tank 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 Inspect the exhaust blanket and exhaust system daily for any signs of leakage. check for worn, cracked, broken, or damaged pipes or muffler. Also check for missing or damaged bolts or clamps. Should any exhaust leaks or defective parts be found, repairs must be made immediately. Engine exhaust leaks can cause fires, do not operate the machine until the exhaust leak is repaired.

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

Clean around filler caps before checking or adding fluids.

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

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.

Clean up all spills immediately.

Always release pressure in hydraulic tank before breaking a connection. For machines with pressurized tanks.

Always use clean oil and containers.

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.

Always install door safety struts when working on machine.

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

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

Clean fire suppression system sensors.

CHECK EMERGENCY EXITS, MONTHLY:

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

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

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

Clean away all branches, bark and chips.

Clean up all traces of oil to avoid fires.

Refer to EMERGENCY EXIT MAINTENANCE GUIDE in SECTION 2 of the OPERATOR'S MANUAL for checking procedure.

SCHEDULED MAINTENANCE ER BOOM SYSTEM

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

WARNING

STICK CYLINDERS FULLY EXTENDED

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

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

TIP OF STICK BOOM FULLY SUPPORTED

FIG.1 - PARKING BOOM

845C-020

HOIST CYLINDER FULLY RETRACTED

TIP OF STICK BOOM FULLY SUPPORTED 845C-021

FIG.2 - PARKING BOOM

(a) The machine is parked on level ground with the attachment on the ground (FIG. 1). (b) The stick cylinders are fully extended (FIG. 1) or the hoist cylinders fully collapsed (FIG. 2). (c) The telescopic boom fully retracted (if equipped) and the tip of the stick boom supported at the rotator pin.

Do not rely on harvester attachment to support the boom system during servicing. Slow leakage in the hydraulic components can cause the attachment to move unexpectedly.

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

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

Lubrication and Maintenance HYDRAULIC TANK PRESSURIZATION INSTRUCTIONS. IMPORTANT! Pressurized hydraulic tank 34.5 kpa (5 psi) maximum.

FILTER/ BREATHER

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 oil 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

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

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 845C-063

Before servicing hydraulic system, release air pressure from tank using air vent valve.

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

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).

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

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

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

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

3.31

Lubrication and Maintenance

OPEN PLUG TO VENT AIR FROM THE SYSTEM

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 OIL GRADE SELECTION 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.

LOOSEN CASE DRAIN HOSE TO VENT AIR FROM THE SYSTEM

VENTING AIR FROM HYDRAULIC SYSTEM

REFILLING THE HYDRAULIC SYSTEM

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.

VENT AIR FROM FITTING

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.

RETURN TUBE STRAINERS/DIFFUSERS There are three reusable strainers on the return tubes. The strainers should be inspected whenever the hydraulic tank is drained. See SCHEDULED MAINTENANCE in THIS SECTION. IMPORTANT! Inspecting, changing or cleaning the strainers should only be performed in the event of a pump or motor catastrophic failure or hydraulic oil contamination.

1. Park machine on level ground with attachment resting on the ground. Position upper structure to allow access to the drain plug in the bottom of hydraulic tank.

2. Stop engine.

3. Open service enclosure doors and install safety strut.

4. Turn BATTERY DISCONNECT SWITCH to the 'OFF' position.

5. Wearing eye protection, release air from the hydraulic tank by opening the AIR VENT VALVE. Pull handle DOWN 90° to open valve.

6. Drain the hydraulic tank via a drain plug in the bottom of the tank.

HYDRAULIC TANK CLEAN-OUT COVER

7. Remove the round access cover (1) and O-ring.

8. Before removing the strainers, clean any debris from the bottom of the tank and wipe it clean.

9. Remove the three hydraulic oil return strainers using the hex on the end of strainer. Carefully clean the strainers (they may be damaged by rough handling).

10. Check for a buildup of foreign materials where the strainers screw onto the pipes and cover plate.

11. Re-install the strainers using the hex on end.

12. Re-install the access cover plate with a NEW O-rings.

13. Add hydraulic oil to tank using fill pump.

14. Close air vent valve (push handle up). Add air pressure to the hydraulic tank via the Schrader valve from a clean air source. Do not exceed 34.5 kPa (5 psi).

15. Bleed air from the main, attachment and fan pumps by loosening the case drain hose fittings at each pump connection.

16. Continue filling hydraulic tank using fill pump.

Tighten case drain hose fittings to pumps when oil is seen coming from the pump case drain ports. It is important that all air is evacuated from the pumps.

17. Fill hydraulic tank up to FULL mark on sight gauge using fill pump.

18. Recheck oil level and add hydraulic oil up to FULL mark using fill pump.

NOTE: Changing strainers and 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 any air bubbles to escape from the oil prior to applying working pressures to the pumps.

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. Refer to AIR INTAKE SYSTEM – AIR CLEANER - ENGINE in THIS SECTION. 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.

PRECLEANER OPERATION

ENGINE AIR PRECLEANER 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.

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

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

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

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.

AIR FILTER ELEMENTS

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.

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

FILTER RESTRICTION INDICATOR

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.

FILTER RESTRICTION SENSOR

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.

860C-019 855D-035

FILTER RESTRICTION INDICATOR A filter restriction indicator is connected to the outlet side of the air filter. Service to the air filter is required when the indicator shows RED. This indicator provides a continuous reading whether the engine is running or is shut down. After servicing the filter, reset the indicator by pressing the reset button on the end of the indicator.

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.

DIESEL OXIDATION CATALYST / SELECTIVE CATALYTIC REDUCTION AFTER TREATMENT SYSTEM (DENOX 2.2 SYSTEM - TIER 4 FINAL)

NOTICE

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

The Diesel Oxidation Catalyst (DOC) uses oxidation at high temperatures to convert carbon monoxide (CO), hydrocarbons (HC) and the soluble organic fraction (SOF) of diesel particulates into inert compounds, carbon dioxide (CO2) and water vapor (H2O). In addition the DOC converts nitrogen oxide (NO) into nitrogen dioxide (NO2).

Increased NO2 levels enhance the performance of the SCR catalyst at low temperatures and increase the effectiveness of the DOC/SCR after treatment system as a whole.

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

• DO NOT IDLE THIS ENGINE FOR MORE THAN 9 HOURS. • DAMAGE TO EMISSION CONTROL SYSTEM WILL RESULT.

63281BENG R0

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

DOC/SCR AFTER TREATMENT SYSTEM

The DOC/SCR after treatment system is electronically managed by the DENOX 2.2 system incorporated into the engine control unit (ECU).

The ECU calculates and adjusts the flow rate of the DEF solution into the system based on current engine speed, torque delivered, exhaust temperature, amount of nitrogen oxides and ammonia present.

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

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

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

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

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

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

DIESEL EXHAUST FLUID (DEF) HANDLING

AVOID DEF QUALITY PROBLEMS WITH PROPER HANDLING PRACTICES

Diesel exhaust fluid (DEF) is an aqueous urea solution with 32.5% high purity urea and 67.5% deionized water. Note that DEF may also be referred to as AUS32 or AdBlue and should meet ISO 22241 specifications. Use only DEF meeting this standard.

Most DEF quality problems can be avoided entirely with a little care and proper handling of DEF fluid.

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

When a problem with DEF quality is detected information messages and warnings will be shown on the computer display. Note that DEF quality problems may result in derating of engine performance to meet emission standard requirements. Action to correct DEF quality problems should be taken immediately to avoid affecting engine performance and damage to SCR after treatment system components. Refer also to COMPUTER – MESSAGES AND WARNINGS in SECTION 2 of the OPERATOR'S MANUAL or SECTION 6 of the SERVICE MANUAL.

FILLING THE DEF TANK •

Always clean the area around the fill cap and avoid introducing contaminants into the DEF tank when filling.

•

Always use only diesel exhaust fluid (DEF) which meets ISO 22241 specifications. Use of any other fluid will contaminate the after treatment system and may pose a safety hazard.

USE OF PROPER STORAGE CONTAINERS •

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

•

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

•

DEF is corrosive to metals other than stainless steel. Transport in metal containers other than stainless steel will result in contamination.

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

WARNING Use only diesel exhaust fluid (DEF) which meets ISO 22241 specifications. NEVER fill the DEF tank with any other fluid.

DEF fluid is injected into the exhaust gas stream during normal operation of the Selective Catalytic Reduction (SCR) after treatment system.

Use of other fluids may cause component damage, or a fire risk which could result in death or serious injury.

PROPER STORAGE CONDITIONS TO MAXIMIZE SHELF LIFE •

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

•

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

•

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

•

DEF shelf life is limited. It should be consumed on a first in first out basis, within manufacturer's recommended shelf life limits.

DEF beyond manufacturer's recommended shelf life limits may not meet ISO 22241 specifications.

Lubrication and Maintenance

Tigercat H855D/LH855D Harvester 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 machine operators will carefully push the boom and attachment down against a suitable obstacle and lift the forward or rear sections of the track off the ground. The operator will then counter rotate the tracks while swinging the upper structure.

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

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

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

Work up or down a slope whenever possible.

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

3.52

Tigercat H855D/LH855D Harvester

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.

MEASURING SAG DIMENSION

5. Measure distance between top surface of track shoe at centre of lower surface of track frame.

NOTE: The track sag fill valve is mechanically restricted from being removed completely.

6. This dimension should be between 4" and 6" for normal operations.

NOTE: If track sag is less than specified, track chain wear will be accelerated. If track sag is excessive, it is possible for the track to jump off the sprocket.

•

Incorrect bolt torque is the leading cause of shoe loosening

•

Torque + turn is the shoe bolts assembly method.

WARNING The grease is under very high pressure.

Removing the fill valve completely may cause the valve to blow out and cause bodily harm.

To loosen the track, slowly loosen the fill valve until grease begins to escape through the vent passage in the valve body housing. Grease will vent around the valve body threads. Remove grease until the track sag dimension is within recommended limits.

Refer to MEASURING TRACK SAG in SECTION 11 of the SERVICE MANUAL for recommended limits.

TORQUE PROCEDURE

•

NOTE: The track sag fill valve is not mechanically restricted from being removed completely.

-

Provides controlled stretch of the bolt (about 0.3 mm). It is the stretch that prevents the bolt from coming loose.

-

Provides up to 25% more clamp load than straight torque.

-

It is not influenced by friction / condition of mating components.

The method is also used on other critical joints, such as sprocket, master sections, final drives. Refer to TORQUE SPECIFICATIONS in SECTION 11 of the SERVICE MANUAL.

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

• Four bolts and washer

WASHERS BOLTS FLANGE CLAMP

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 on to 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.

Flange Port Assembly

FLANGE HEAD O-RING TAPPED HOLES

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.
