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 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.

GENERAL SAFETY PRECAUTIONS continued

Check all fluid levels.

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

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

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

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

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

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

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

Some advice which should be observed: • 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.

• Don't put oily rags in your pockets.

• Oil soiled clothing should be changed as soon as possible.

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

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

• Avoid breathing in oil fumes.

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

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

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

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

Machine should be washed completely at every major service.

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

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

Check windows and door guards for damage.

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

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

1.6

Tigercat H822C/LH822C/H830C/LH830C Harvester

Safety

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

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

GENERAL SAFETY PRECAUTIONS continued Safety Hazards - Viton Seals 'O' rings and other seals manufactured of Viton material (fluorine rubber) produce a highly corrosive acid (Hydrofluoric) when subjected to temperatures above 600°F (315°C).

Maintain a distance of 10 ft. (3m) between the machine or boom and any power line carrying up to 50,000 volts or less plus 1/2 inch (10mm) for each addition 1,000 volts above the 50,000 volt level.

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

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

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

If the machine must be transported, make sure that it is adequately secured to the transporting vehicle. Refer to the vehicle moving instructions page in SECTION 2 of the OPERATOR'S MANUAL.

• Visually inspect any seals or gaskets which have suffered from heat damage; they will appear black and sticky.

• If these are found, DO NOT TOUCH!!!

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 5 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.

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

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

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

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

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

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

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

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

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

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

WARNING

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.

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.

Anyone opening the door or screen and holding on to it could be pulled out of the cab and injured.

MACHINE STABILITY AND TRACTION MACHINES WITHOUT LEVELER When working on slopes, travel straight up or down the slope to prevent roll-over.

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

• To avoid tip over, keep the felling head as low as possible to maintain a low center of gravity.

• 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 rollover.

OPERATING SAFETY PRECAUTIONS continued MACHINE STABILITY AND TRACTION MACHINES WITH LEVELER This machine is designed to operate on rough terrain and slopes commonly found in forestry applications. However, ground conditions vary greatly with changing soil types, slope angles, moisture, snow and ice, rocks, boulders, stumps, and fallen trees. All of these factors affect the stability of the machine and may cause tip-over and loss of traction. This machine may not be capable of operating on some ground conditions, and must be used with caution.

26°

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

FIG. 2 UNDERCARRIAGE LEVELING All efforts have been made in the design of the machine to reduce the risk of tipping, however it is not possible to completely eliminate all risk of tipping. To minimize the risk of tipping observe the following: • Do not attempt to operate this machine on slopes without first receiving proper training.

• Learn the stability limits (FIG. 2) or feel of the machine by first working on gentle slopes and by positioning the boom to reduce the risk of tipping. Gain experience over time by gradually increasing the angle of the slopes on which you are working.

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

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

• Travelling at an angle to a 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.

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

KEEP ATTACHMENT CLOSE TO GRADE

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

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

• When climbing a slope the boom should face uphill and the attachment should be kept close to the ground (FIG.3). When descending a slope the boom should face down hill and the attachment should be kept close to the ground (FIG.4). Be aware that the machine is in its least stable postion on a slope with the boom to the rear (see also FIG.1). Be particularly aware of machine stability when changing directions on, or travelling back down a slope.

Safety

Tigercat H822C/LH822C/H830C/LH830C Harvester In the event of any suspected fluid injection injury • Report the injury to your supervisor IMMEDIATELY. • Seek professional medical attention IMMEDIATELY. As always, the best defence against suffering the effects of fluid injection is to prevent the accident from occurring in the first place.

When searching for possible fluid leaks: • Never search for leaks with your bare hands.

Always wear thick protective gloves.

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

Hydraulic and diesel fuel systems on forestry machines operate at very high pressures, often 207 bar (3000 psi) and above. If a loose connection or a defect in a hose should occur, a fine, high velocity stream of fluid will result. Even for systems pressurized to as little as 7 bar (100 psi), this fluid stream can penetrate human skin as if it were a hypodermic needle.

• Be sure to wear safety goggles for eye protection.

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

• Wear proper protective equipment 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 that protective shrouds are installed on all grease gun nozzles as safety devices.

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

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

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

LIGHTNING SAFETY AWARENESS

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.

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

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

1. Designate a member of your crew to: • Monitor daily weather forecasts • Observe local weather conditions

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.

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

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

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 thus, strikes occur 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.

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.

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

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

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.

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

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.

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

LIGHTNING SAFETY AWARENESS continued

If you can, get inside.

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

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.

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

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

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.

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

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.

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

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.

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

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

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.

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

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.

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

FIRE PREVENTION

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.

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

The following fire prevention guidelines should be used to supplement 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 this manual.

3. Blow off all forest debris and fine organic material accumulated near hot engine exhaust components (turbocharger and exhaust manifold as well as exhaust pipes and muffler) at the completion of each work shift or more frequently when working in logging conditions where large amounts of combustible forest debris are present. It is vital to conduct a visual inspection after blow off to ensure thorough cleanliness.

Engine exhaust systems provide numerous small pockets where saw dust, small wood chips and other flammable forest debris can gather. Even small accumulations close to hot exhaust components can ignite and smolder.

If dislodged this smoldering debris can fall into other areas of the machine and thereby spread a fire.

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

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

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

9. Inspect the exhaust system daily for any signs of leakage. Check for worn, cracked, broken or damaged pipes or muffler.

Also check for missing or damaged bolts or clamps. Should any exhaust leaks or defective parts be found, repairs must be made immediately. Engine exhaust leaks can cause fires. Do not operate the machine until the exhaust leak is repaired.

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

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

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

1.27

Safety

Tigercat H822C/LH822C/H830C/LH830C Harvester 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.

FIRE PREVENTION continued 13. Turn the battery disconnect switch to OFF at shut down to de-energize all electrical circuits.

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

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

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.

Safety

Tigercat H822C/LH822C/H830C/LH830C Harvester • Place the nozzle of the fire extinguisher into the appropriate fire extinguisher access hole and discharge the extinguisher.

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

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

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

• Remain with the machine until help arrives.

FIRE PREVENTION continued 4. If in any doubt about whether or not to fight the fire – DON’T. Instead, stand well clear of the fire and wait for help to arrive.

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

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

WHAT TO DO AFTER A MACHINE FIRE HAS OCCURRED Before returning the machine to work: 1. Ensure that the cause of the fire is determined and all appropriate repairs are completed.

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

Safety

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.

FIRE PREVENTION continued DRY CHEMICAL CLEANUP PROCEDURES

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

Both ABC dry chemical fire extinguishers and fire suppression systems discharge a chemical powder to extinguish the fire. The chemical makeup and the small particle size of the powder as well as the force of the discharge all contribute to the fire fighting capability. These same characteristics also permit the powder to penetrate into and fully cover all components in the vicinity of the discharge.

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

The caked dry chemical when exposed to moisture is also mildly acidic. Therefore when the break down procedure has been completed, follow this immediately with the neutralizing procedure as described in step 2

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

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

.

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

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

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

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

2. In areas exposed to moisture, the dry chemical powder will combine with water to form a paste that is mildly acidic.

NOTE: 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.

5. IGNITION KEY SWITCH This is a three-position switch with STOP/RUN/START positions.

It is most important that the IDLE and FULL rpm’s of the engine be correct at all times: IDLE - 950 rpm (No Load)

STOP Position - All electrical power through the key switch is turned OFF.

FULL - 1900 rpm max (No Load)

NOTE: Electrical power is still available for the horn, lighter, CD AM/FM radio, two-way radio, cab dome light, defroster fan, work lights and service lights.

NOTE: The engine always defaults to IDLE at start-up.

RATED WORKING - 1800 rpm

NOTE: These speeds are with the hydraulic and engine oil at normal operating temperatures, without the pilot systen engaged and with no functions activated.

These speeds are preset into the engine CPU (computer) and cannot be adjusted without the proper electronic equipment programming software. Check the engine speed regularly using the engine diagnostics module.

RUN Position - The battery is connected to all functions. Used for normal machine operation.

START Position - Connects the battery to the start relay to start the engine.

Turn the key to this position to start the engine. The key returns to the RUN position when released.

IMPORTANT! Under no circumstances should the FULL throttle engine speed be permitted to vary from the recommended settings, particularly faster, as this could cause serious damage to the pumps.

NOTE: The PILOT SYSTEM must be OFF to start the engine. To deactivate the pilot system, push the red PILOT SYSTEM OFF push button switch (item 9, on the rear control panel).

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

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

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

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

12. CIGARETTE LIGHTER (24V)

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

Cigar/Cigarette lighter (24V).

13. SAW - SWITCH This is a two-position switch labeled ON/OFF. Use this switch to turn the saw ON. On Harvester model machines, this saw switch supplies power to the attachment control system. A lockout button is incorporated into the switch to prevent the switch from being turned ON accidentally.

HIGH: Place the switch in the DRIVE position to provide faster travel speed range but with a lower driving force.

Push and hold the lockout button UP and place the switch in the ON position to turn the switch ON.

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

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

NOTE: The available torque when travelling at maximum speed is only half of that in LOW. The DRIVE position provides a faster travel speed range but with a lower driving force.

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

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

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

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

14. AUXILIARY POWER OUTLET (12V)

FULL ON (OVERRIDE) DOWN POSITION When the switch is in the FULL ON (OVERRIDE) position, the fan control system is overridden and the fan runs at FULL speed for cooling regardless of charge air, coolant or oil temperatures. Normally the fan control switch is placed in the AUTO position for optimal cooling. The FULL ON (OVERRIDE) position is intended for use in the event of a temporary failure of the fan control.

This is a 12V outlet with a 15A capacity for portable devices such as cell phones.

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

AUTO POSITION - AUTO is the normal operating position for the fan control switch.

When the switch is in the AUTO position, the fan operates completely in an automatic mode. It starts, speeds up or slows 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.

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 disabled.

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, turn ON the A/C to increase the cooling fan speed when 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.

2.20

Tigercat H822C/LH822C/H830C/LH830C Harvester 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 expels debris.

CLEAN - UP POSITION - Momentarily pressing the switch to the CLEAN position automatically starts 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.

Reversing the flow of the fan, propels air in the opposite direction, thereby forcing dust and debris off of the radiator.

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

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

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

NOTE: The CLEAN cycle also operates automatically via the timed purge function of the computer control system (frequency is adjustable). Refer to COMPUTER - INFORMATION MESSAGES and COMPUTER - DIAGNOSTIC - ADJUST FUNCTION PARAMETERS in this section.

NOTE: If engine speed falls to 875 rpm or less the speed control is automatically overridden and fan speed defaults to the forward direction.

1. Remove the locking pin (2).

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. Also, the control panel automatically shuts 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 turn OFF engine manually.

The automatic engine shutdown feature either shuts down the engine immediately when the fire suppression system is discharged (non leveling machines) OR it delays 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.

Controls and Operation

NAB

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

D

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

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

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

PROBLEMS AND CORRECTIVE ACTION

SEAT TOO HIGH/SEAT TOO LOW There are several things which can cause improper seat height. Refer to HEIGHT ADJUSTMENT PROCEDURES 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 HEIGHT ADJUSTMENT PROCEDURES.

OPERATOR’S LEGS FALLING ASLEEP The seat is adjusted too high, and the air ride control valve has under pressurized the seat air suspension ride adjustment, resulting in the operator sitting in a bucket. Refer to HEIGHT ADJUSTMENT and RIDE ADJUSTMENT PROCEDURES.

RIDES TOO SOFT OR BOTTOMS OUT AND PINCHES OPERATOR The air ride control valve has under pressurized the seat air suspension ride adjustment Insufficient pressure exaggerates the knee-action movement of the seat. This usually happens because the operator is trying to lower the seat by decreasing the amount of air pressure instead of using the height adjustment lever. Refer to HEIGHT ADJUSTMENT PROCEDURES.

CURRENT OUT (COUT) The COUT channel maintains a constant output current to control proportional solenoids. The voltage is regulated to maintain the constant current based on the resistance of the circuit.

These settings (defined below) fine tune the operating speeds and start/stop ramps for the adjustable current out operated functions.

MIN = MINIMUM CURRENT (mA) Minimum current settings control function start speed. Coils on hydraulic valves require a certain amount of current before they begin to operate the valve. The Min current value is the current that is sent to the hydraulic valve coil when the function switch is activated.

NOTE: See the description of MIN/MAX CURRENT, START/STOP RAMP and +Plus/-Minus on this page.

The min current is adjusted to a value that causes the function to just begin to move.

MAX = MAXIMUM CURRENT (mA) Maximum current settings control the maximum speed at which the function operates.

Min Current is the first choice that can be adjusted. The range is 0 to 750 mA. Scroll UP/DOWN to change the value, then press OK.

START/STOP RAMP Start and stop ramp is the time it takes for the current to rise/fall from minimum to maximum and maximum to minimum respectively.

The selection moves to the next adjustment, Max Current.

+Plus = Cylinder Extend or Rotate CW -Minus = Cylinder Retract or Rotate CCW

Max current adjustment range is 0 to 750 mA. Scroll UP/DOWN to change the value, then press OK. The selection moves to the next adjustment.

In this example Start/Stop Ramp adjustments are locked as they do not apply to cylinders.

SPN: 110 FMI: 16 1 of 1 Engine coolant temperature high Above normal, severe

Alert engine fault message(s) are displayed, the alarm sounds and the alarm warning light flashes when an alert engine fault message is received from the engine electronic control module.

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

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

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

When an information message is displayed on the screen, the message either automatically disappears when the condition no longer exists or it stays on the screen until the operator acknowledges the message.

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

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

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

NOTE: Some less common engine fault codes appear without a message describing the fault.

HYDRAULIC OIL TANK

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

Located at the left-rear corner of the machine beside the fuel tank, the hydraulic tank has a capacity of 166 L (44 US gal) with a total machine dry fill capacity of 250 L (66 US gal).

Incorporated into the base of the top gauge is a low level sending unit connected to the MD3 computer. An Alert message is displayed and the hydraulic oil level icon displays in YELLOW when the oil level falls to this point. The master alarm sounds and the alarm light flashes three times.

Six full-flow filters are connected to the hydraulic tank and mounted on three filter heads with builtin bypasses. The filters are located above the hydraulic tank.

A temperature sender activates the temperature gauge on the MD3 computer. The hydraulic oil temperature icon displays BLUE during the warmup mode and changes to WHITE in normal operating temperature. Should the temperature rise above normal, the icon changes to YELLOW.

A second oil level sight gauge located in a LOWER position on the tank than the first sight gauge, also incorporates a low level sending unit connected to the MD3 computer. A Critical message is displayed and the hydraulic oil level icon displays in RED if there is a further loss of oil down to this point. The master alarm sounds and the alarm light flashes continuously. STOP the vehicle, check for leaks and fix if needed, and refill the hydraulic oil tank to the suggested level.

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

Always keep the hydraulic oil level to within 5 cm (2 in.) of the HIGH mark. A low hydraulic oil level can result in severe damage to the pumps.

There are four reusable strainers/diffusers housed in the hydraulic tank: one (horizontal) on the case drain return port and three (vertical) on the return tubes.

The majority of the return oil entering the tank passes through six spin-on hydraulic oil filters.

The blue filter is a water absorbing filter which is in place to assist with removing unwanted moisture from the hydraulic oil. The filters are connected in parallel to three separate return filter heads.

NOTE: Inspecting, changing or cleaning the strainers should only be performed in the event of a pump or motor catastrophic failure or hydraulic oil contamination.

IMPORTANT!

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

Filters must be replaced at the recommended time intervals. See SECTION 3 in this manual.

Use of filters other than genuine Tigercat replacement filters is not recommended.

IMPORTANT! DO NOT use these warnings as a substitute for checking the oil level at regular intervals as per the SCHEDULED MAINTENANCE program in SECTION 3 of this manual.

This information is assuming that operating conditions and running temperatures are NORMAL. FILTER/STRAINER SERVICE NOTE: The filters should be checked/changed when the oil filter bypass icon displays YELLOW on the MD3 computer. If the icon continues to display YELLOW after the filters have been changed, the return strainers attached to the base of the return tubes in the hydraulic tank should be examined for possible obstructions.

IMPORTANT!

NEVER PREFILL HYDRAULIC FILTERS

822C-222

HYDRAULIC OIL HEATER (OPTIONAL)

HYDRAULIC OIL HEATER (OPTIONAL) The hydraulic tank heater uses engine coolant to warm the hydraulic oil. There is a solenoid valve controlling the flow of coolant to the tank heater; this solenoid valve is controlled directly by the Webasto unit. The programming of the Webasto unit in the cab determines when the heater is ON and when it turns OFF.

Tigercat does not recommend the prefilling of spin-on filters due to the risk of damage to the hydraulic system caused by unfiltered oil. Unfiltered oil used to prefill 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 prefiltered before use.

HYDRAULIC HAND FILL PUMP

HYDRAULIC OIL HAND FILL PUMP The hydraulic oil hand fill pump, located on the left-rear door, is used for adding oil to the hydraulic oil tank. Hydraulic oil is pumped directly into the hydraulic tank via the return filter manifold This ensures that any hydraulic oil added is filtered prior to entering the hydraulic tank.

Refer to APPROVED HYDRAULIC OILS - MAIN HYDRAULIC SYSTEM in SECTION 3 of this manual.

ADDING OIL TO HYDRAULIC TANK Depressurize the tank, thoroughly clean the outside surface of the suction tube and remove the plug. Open the oil fill shut-off valve, insert the end of the suction tube into the supply drum and operate the pump. The pump should always be operated at a medium speed with steady motion.

Pumping too fast may cause oil to bypass the oil filter.

IMPORTANT! Close the shut-off valve, replace the cap on the suction tube, wipe it dry, and store it after filling.

Failure to keep the suction tube clean significantly reduces the life of the filter elements. Swing the pump handle up and lock.

CLEANING PROCEDURE: 1. Turn OFF the engine as per the instructions in STOPPING ENGINE in this section. Always follow proper engine shutdown procedures.

The important benefits are:

The hydraulic oil cooler/radiator/charge air cooler (CAC) is mounted to the rear of the fan. The A/C condenser core is mounted to the rear of the oil cooler. A debris screen is used to protect the oil cooler/radiator/CAC cooling assembly. The hydraulically driven fan draws air through the screen, through the A/C condenser, the oil cooler/ radiator/CAC cooling assembly and finally blows the air across the engine.

• Extended life of engine, cooling and exhaust systems.

• Reduced risk of post shutdown fires.

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

The A/C condenser core and the oil cooler/ radiator/CAC cooling assembly should be checked every shift (8 hours) for accumulation of twigs, leaves, pine needles, dust and all other debris. All of the engine enclosure doors should also be kept clean.

2. Open the right-rear side engine door.

3. Slide the debris screen out.

4. Remove the two nuts (right side) and carefully swing out the A/C condenser (on hinges) to expose the oil cooler/radiator/CAC cooling assembly. Remove any accumulated debris.

TRAVELLING (BOOM RAISED)

OPERATING TIPS WITH LOAD SENSING

1. Select the appropriate drive range.

When using the controls on a load sensing system, be aware of what the load sensing system is trying to do for you. If you move the lever or pedal 20% of its total angle, the system provides 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 overshoot the speed you wanted.

Relax and try to use the least amount of lever action you can.

Place the track switch in the LOW or DRIVE position.

When in LOW, the machine moves slower but with increased drive force. All harvesting should be done in LOW. When in DRIVE, the machine moves faster but with less drive force. Travelling over longer distances (and not harvesting) should be done in DRIVE to allow for faster travel speeds, when the terrain permits. Also, DO NOT travel continuously for longer than 10 minutes, take 5 minute breaks, this helps prevent the track drive gearboxes from overheating.

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 machine response.

For a more detailed description of drive range, refer to TRACK, LOW/DRIVE SWITCH in this section.

2. Place the swing brake switch in the OFF position.

Refer to SET MARGIN PRESSURE in SECTION 4 of the SERVICE MANUAL

3. Move the throttle control to the HIGH idle position.

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

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

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

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

OPERATING THE MAIN BOOM IN THIS ZONE WITH A FULL LOAD DOES NOT ALLOW THE HORIZONTAL REACH MOTION TO PERFORM AS IT SHOULD WITHOUT ASSISTANCE FROM THE RIGHT JOYSTICK

2. Refer to HARVESTING ATTACHMENT GENERAL SAFETY in SECTION 1 of this manual.

3. Read and understand the operating and safety instructions found in the ATTACHMENT MANUFACTURER’S MANUAL for the attachment installed on this machine.

H822-03

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 are certain conditions in which the weight of the head plus its carried load are 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 CAB WINDOWS

1. Ensure that all fluid levels are always at the proper level. Refer to the LUBRICATION AND MAINTENANCE SCHEDULE 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.

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

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

Polycarbonate windows are an essential piece of operator protective equipment and should be maintained as such.

IMPORTANT! Cracks, chips, notches or scarring anywhere on the viewing surface or edges of the window, decrease its 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.

2. Lubricate all grease points at the required intervals as specified in the LUBRICATION AND MAINTENANCE SCHEDULE in SECTION 3 of this manual.

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

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 EXIT MAINTENANCE guide in this section.

6. DO NOT allow branches, twigs, leaves, pine needles or any other debris to build up around radiator intake doors or anywhere else on the machine. Clean as operating conditions warrant but at least once a day all debris must be remove from the machine interior.

7. DO NOT apply a load to a cold engine.

8. Always harvest trees in LOW driving range.

9. Never park the machine with the attachment raised off the ground. Be sure that the attachment 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.

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

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 decrease its 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 its ability to resist heavy impacts.

Windows with these defects must be replaced imeediately.

• 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.

• Air conditioning refrigerant • Ammonia • Antifreeze • Benzene • Brake fluid • Carbon tetrachloride • Cutting oils • Gasoline • Lacquer thinner • Toluene • Turpentine • Xylene RESISTANCE TO WATER Polycarbonate material has good resistance to water up to approximately 65°C (150°F). Above this temperature the effect of water is timetemperature related. This means that the higher the water temperature, the shorter the time before the polycarbonate is adversely affected.

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

2.87

Controls and Operation

Tigercat H822C/LH822C/H830C/LH830C Harvester

CLEANING INSTRUCTIONS

CAUTION

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

• DO NOT use abusive cleaning procedures either by hand or pressure washing on polycarbonate windows.

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

• DO NOT clean polycarbonate windows when the daytime temperature is high or in direct sunlight.

• DO NOT use abrasive or highly alkaline cleaners on polycarbonate windows.

• DO NOT use glass cleaners in either aerosol or nonaerosol containers to clean polycarbonate windows.

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

The following instructions are provided to prolong the life of this protective hard coating: 1. Rinse the window thoroughly with lukewarm water 2. Using a soft cloth, cellulose sponge or chamois, gently wash the window with a mild solution of soap or detergent in lukewarm water. DO NOT scrub or use brushes or squeegees.

Brand name soaps and detergents recommended for cleaning polycarbonate are: • Fantastik • Formula 409 • Hexcel F.O. 554 • Joy • Lysol

CONCEALING HAIRLINE SCRATCHES

• Mr. Clean

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

• Neleco-Placer • Pine-Sol

• Johnson’s Paste Wax

• Top Job

• Novus Plastic Polish #1 and #2

3. Rinse the window thoroughly with lukewarm water.

• Mirror Glaze Plastic Polish

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

Be certain to clean the polycarbonate window as outlined prior to application of an automotive polish. Refer to CLEANING INSTRUCTIONS.

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

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

2.88

Tigercat H822C/LH822C/H830C/LH830C Harvester

Controls and Operation

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

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

WINDOW SCREEN HAND KNOB

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

860C-396

SIDE WINDOW SCREEN

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

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

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

REMOVAL OF ANTI-CORROSION SPRAY (IF APPLICABLE)

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

Some machines, particularly machines shipped outside North America, are shipped with an optional anti-corrosion spray to protect the machine from corrosion during shipment.

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

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

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 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.

HYDRAULIC OIL SAMPLE VALVE

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.

822C-187

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

• Purge the sample valve before taking a representative oil sample. Drain a minimum of 90 to 120 ml (3-4 ounces) of oil into a separate container and discard this oil using approved recycling methods.

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

• 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.

Gearbox Samples: • 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).

• 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.

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

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

• 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.

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

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

GENERAL 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.

Always use clean oil and containers.

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.

Drain dirty oil while still warm.

Always have a fire extinguisher at hand.

Do not exceed recommended fluid levels.

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

Clean up spills as soon as possible.

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

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

Always install door safety struts when working on machine.

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

Clean fire suppression system sensors.

Clean up oil spills on walking surfaces in engine enclosure immediately.

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.

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

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

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

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

1. Forest debris and fine organic material (twigs, pine needles, branches, bark, leaves, saw dust, small wood chips) and any other combustible materials when allowed to accumulate, form a fuel source that when ignited is extremely difficult to extinguish. A thorough program of regular cleaning and washing will reduce the possibility of a fire starting. In the event a fire does start, the regular cleaning program will improve the chances of successfully extinguishing a fire.

OPEN/CLOSE LEVER 822C-243

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

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

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

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

Also refer to FIRE PREVENTION in SECTION 1 of this manual for additional information.

SCHEDULED MAINTENANCE FREQUENTLY:

• ‡ Boom joints: Conventional Boom: 6-fittings - purge Conventional w/Tilt Link: 12-fittings - purge ER Boom System: 12-fittings - purge • ‡ Cylinders; boom, stick & tilt: Conventional Boom: 8-fittings - purge ER Boom System: 10-fittings - purge

• Check engine cooling air intake screens for possible restrictions.

• In broad leaf applications it may be necessary to reverse the cooling fan as frequently as every 10 minutes.

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

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

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

STICK CYLINDERS FULLY EXTENDED HEAD FLAT ON GROUND H822-01

When performing maintenance procedures or setting up a machine equipped with an ER boom system, the following points must be noted: The main and stick boom cylinder circuits are connected hydraulically. Thus, disconnecting a hydraulic line to a boom cylinder may cause either boom to move unexpectedly. The boom 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 boom and head. Ensure that the boom is properly parked for service (see FIG.1 & FIG.2) and the engine is turned OFF before disconnecting any hydraulic lines. Also, for machines equipped with pressurized hydraulic tanks, relieve pressure in the hydraulic reservoir by opening hydraulic tank vent valve and waiting until the sound of escaping air stops.

FIG.1 - PARKING BOOM

HOIST CYLINDER FULLY RETRACTED TIP OF STICK BOOM FULLY SUPPORTED H822-04

FIG.2 - PARKING BOOM

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

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

3. The telescopic boom (if equipped) fully retracted and the tip of the stick boom supported at the rotator pin (FIG.2).

4. DO NOT rely on the 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: Due to the hydraulic connection between the main boom and ER cylinders, the ER cylinder can overpower the stick cylinders under certain conditions, causing the stick boom to move unexpectedly. This most often occurs when setting the MAIN BOOM UP relief valve, causing the stick 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.

FILTERS - REMOVE AND REPLACE

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

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

Tier III and IV engines typically use filters with a very fine micron rating. If the fuel supply is dirty, the fuel filter must be replaced more frequently than recommended in the owner’s manual. Operating the machine with a clogged fuel filter will result in low engine power. It is also recommended that the fuel/water separator bowl be drained daily.

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

When installing a new fuel filter, DO NOT prefill with diesel fuel, or engine fuel pump damage will result. This type of failure is not warrantable by the engine manufacturer.

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

HYDRAULIC FILTER SERVICING GUIDELINES

To release pressure from the hydraulic tank:

IMPORTANT!

IMPORTANT! NEVER PREFILL HYDRAULIC FILTERS

PRESSURIZED HYDRAULIC TANK 34.5 KPA (5 PSI) MAXIMUM

Before servicing the hydraulic system, release the air pressure from the tank using the air vent valve. Eye protection is required.

Tigercat does not recommend the prefilling of spin-on filters due to the risk of damage to the hydraulic system caused by unfiltered oil. Unfiltered oil used to prefill 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 prefiltered before use.

CHECK VALVE 10 psi AIR VENT VALVE

822C-243

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

Wearing eye protection, release air from the hydraulic tank by opening the AIR VENT VALVE. Place the OPEN/CLOSE lever in the open position.

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

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

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

WARNING, HOT FLUIDS AND HOT MACHINE SURFACES CAN CAUSE SERIOUS BURNS!

•

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

•

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

Lubrication and Maintenance

REFILLING THE HYDRAULIC 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.

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

The pilot filter has to be removed and reverse flushed every 1000 hours as part of scheduled maintenance. A clogged filter will result in low pilot pressure. When a clogged condition is indicated by a loss of controls or slow response the pilot filter will need to be serviced at an earlier interval.

HYDRAULIC HAND FILL PUMP

The hydraulic hand fill pump, located on the rear left door, is used for adding oil to the hydraulic oil tank. Hydraulic oil is pumped directly into the hydraulic tank via the return filter manifold This ensures that any hydraulic oil added is filtered prior to entering the hydraulic tank.

Refer to APPROVED HYDRAULIC OILS - MAIN HYDRAULIC SYSTEM in SECTION 3 of this manual.

Refer to FILTER AND LUBRICATION SCHEDULE in THIS SECTION for recommended servicing intervals.

Refer also to SECTION 5 of the SERVICE MANUAL for more information.

ADDING OIL TO HYDRAULIC TANK Depressurize tank, thoroughly clean outside surface of the suction tube and remove the plug. Open the oil fill shut-off valve, insert end of suction tube into supply drum and operate the pump. The oil is pumped directly into the hydraulic tank via the return filter manifold. The pump should always be operated at a medium speed with steady motion. Pumping too fast may cause oil to bypass oil filter.

IMPORTANT! Close shut-off valve, replace cap on suction tube, wipe dry, and store after filling. Failure to keep the suction tube clean will significantly reduce the life of the filter elements. Swing pump handle up and lock.

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.

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

NOTE: The safety element needs to be replaced on 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.

OUTLET TUBE PRIMARY ELEMENT

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

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

4. Always clean the inside of the outlet tube.

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

SAFETY ELEMENT

822C-233

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.

AIR FILTER ELEMENTS

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

6. Inspect the new filter for damage.

In addition to the LUBRICATION AND MAINTENANCE SCHEDULE outlined in this section, it should be noted that the most common and most damaging air intake servicing problems are over servicing and imporper servicing.

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

8. Check connections and ducts for air tight fit.

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

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.

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

Remove the unloader valve from the tube of the air cleaner housing. A good valve is soft and flexible. Check and clean the valve. If it was plugged, then check the filter elements as they may need to be replaced as well. Reattach the valve to the tube. The valve should suck closed at about 1/3 of full throttle. When operating in extreme high dust conditions this valve should be checked and squeezed frequently to release dust accumulation.

TRACK OPERATION AND WEAR PREVENTION

Alternate turning directions.

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

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.

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.

In the event a counter rotation is required some operators will carefully push the boom and attachment down against a suitable obstacle and lift the forward or rear sections of the track off the ground. The operator will then counter rotate the tracks while swinging the upper frame. This will disengage most of the track length from the ground during the counter rotation resulting in less site damage and potentially less track wear.

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

Inspect the undercarriage before you start working.

In addition to ensuring that the undercarriage is clean, spend a couple of minutes on a visual inspection. Check for loose bolts, leaky seals and abnormal wear patterns. When you spot potential problems early, you can often prevent them from turning into bigger issues that reduce component life significantly or cause expensive unscheduled downtime.

Don't spin the tracks.

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

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

Watch your speed.

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

Work up or down a slope whenever possible.

Avoid unnecessary reverse operation.

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

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

3.40

Tigercat H822C/LH822C/H830C/LH830C 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:

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.

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.

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.

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.

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

• 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.

6. This dimension should be between 10-15 cm (4-6 in.) 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. Refer to TRACK CHAIN TENSION ADJUSTMENT PROCEDURE IN SECTION 11 of the SERVICE MANUAL. 3.42

Assembly Torque

The 4-Bolt Split Flange consists of four main components:

The four-bolt port is simply a circular opening (flow passage) surrounded by four tapped holes in a certain pattern for acceptance of the flange clamping bolts.

The flat surface of the port compresses the O-Ring contained in the groove in the flange head when the clamp bolts are torqued. In some instances, the groove is in the port and not in the flange head. The bolts, through the clamp halves, clamp down the flange head onto the flat surface of the port compressing and trapping the O-Ring in the groove and leaving no gap for it to extrude under pressure. The hydraulic pressure is thus sealed by the compressed O-Ring as long as the bolts are tightened enough to maintain solid metal to metal contact between the flange head at the outside diameter of the O-Ring and the top of the port.

• A body (flange head) • An O-Ring • One “captive” or two “split” flange clamps

• Four bolts and washers

WASHERS BOLTS FLANGE CLAMP

Flange Port Assembly The steps to properly assemble the flange port clamping bolts are:

FLANGE HEAD

1. Make sure sealing surfaces are free of burrs, nicks, scratches or any foreign particles.

O-RING TAPPED HOLES

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.
