WORKING WITH OIL

SAFETY HAZARDS – VITON SEALS

Direct contact with oil implies a risk of skin complaints (example: eczema). Observe strict hygiene.

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

Observe the following when working with oil: • Oils used in this machine may be hot enough to cause serious burns.

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

• Avoid contact with oil, particularly heated oil.

• Wash off oil on the skin immediately with soap and water.

• Wear protective gloves. Clean hands before putting on gloves. Apply protective cream to the hands to make washing easier.

• Don't put oily rags in your pockets.

• Change oil soiled clothing as soon as possible.

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

• Attend to cuts and abrasions immediately. Clean them and apply first-aid.

• Avoid breathing in oil fumes.

The following procedures are recommended when inspecting equipment subjected to high temperatures such as fire: • 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! • Determine the material composition of any seals or gaskets, If fluoroelastomer 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).

• Wash hands and arms frequently, for example, at each meal break or as often as possible.

• 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.

MACHINE STABILITY AND TRACTION This machine is designed to operate in rugged terrain.

However, ground conditions vary greatly according to soil type, slope, moisture level, temperature, season, geology, and vegetation. These factors affect the machine's stability and tractive capabilities. The machine may not be suitable for some ground conditions. Use caution when assessing the terrain in the work area Observe the following approaches to minimize the risk of tipping: • Do not operate this machine on slopes.

• Do not travel across a steep slope or hillside.

• When crossing obstacles (boulders, stumps, or ditches) the machine can shift rapidly, greatly affecting its stability. Move slowly over obstacles to reduce the risk of the machine shifting rapidly.

1.16

Tigercat 6900 Grinder

Safety

FLUID INJECTION INJURY

Prevention is the best defence against fluid injection injuries.

WARNING

When searching for possible fluid leaks:

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.

• Do not use bare hands. Wear thick protective gloves at all times.

• Wear safety goggles; a face shield is also recommended.

• Keep all body parts well away from the potential leak zone.

Hydraulic oil and diesel fuel systems in forestry equipment operate at very high pressures —often above 200 bar (3000 psi).

If a hose fitting becomes loose or a hose ruptures, the leak point will emit a fine, high velocity stream of fluid.

Even in systems that operate at pressures as low as 7 bar (100 psi), a fluid stream can penetrate human skin as if it were hypodermic needle.

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

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

An accidental hypodermic fluid injection may, at first, create only slight stinging sensation. Within a short time, however, the wound will begin to throb painfully, indicating that tissue has already been damaged.

If fluid injection penetrates a blood vessel, it can rapidly spread throughout the body's circulatory system. The body is unable to purge this toxin.

Time is a critical factor that influences fluid injection injuries. If a fluid injection injury occurs, or is suspected, it is vitally important to seek medical attention immediately. Tissue damage will continue to occur until the injury is treated.

Although fluid injection injuries are relatively rare, the resulting injuries have, on occasion, resulted in the amputation of fingers, hands, or entire limbs. The longer the delay in seeking medical attention, the further up the limb the tissue damage will reach. An injury of this nature can have extremely grievous consequences —including death —if not treated promptly and correctly.

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

• Seek professional medical attention immediately.

1.17

• Recognize that the leak source and the fluid stream itself may be nearly invisible. Pooling of fluid may be the clearest evidence of a leak.

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

• Do not grab hold of any hydraulic or diesel fittings or hoses that are pressurized.

• Use the correct hoses and fittings for repairs; they must be rated for the pressures to which they will be subjected.

• Do not use hoses or fittings if defects or damage are suspected.

GREASE INJECTION INJURY– PNEUMATIC GREASE GUNS Pneumatic grease guns can pump grease at pressures ranging from 17 – 400 bar (245-5800 psi). Fluids at pressures as low as 7 bar (100 psi) can penetrate human skin.

Seek professional medical attention immediately in the event of a grease injection injury. Provide the attending physician with as much information as possible: the type of grease, the pressure setting of the gun, and related details.

In the event of a grease injection injury, the volume of material injected, the pressure at which it was injected, and the time elapsed between injection and medical treatment will influence the chance of successful recovery.

Before using a pneumatic grease gun: • All users must be trained to operate it properly.

• All users must be familiar with the hazards involved, and necessary safety precautions.

When using a pneumatic grease gun: • Wear protective clothing, such as gloves, safety goggles, and safety helmet.

• Inspect the grease gun equipment for damage or wear; replace damaged or worn parts.

• Verify that protective shrouds are installed at the grease gun nozzles.

• Remove dirt and old grease from grease fittings prior to pumping fresh grease.

• Replace any defective or damaged grease fitting on equipment with new fittings.

• Replace awkwardly situated fittings with angled or swivel fittings for ease of access.

LIGHTNING SAFETY AWARENESS

LIGHTNING SAFETY

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.

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

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

Personnel can increase their chances of avoiding a lightning strike by following a few simple safety practices: • Designate a member of your crew to: • Monitor daily weather forecasts • Observe local weather conditions • Alert all other members of the crew when a possible lightning threat develops • Do not 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 miles). Lightning travels both in front of and behind a thunderstorm and so strikes happen even when rain has not started or has stopped. Lightning can hit in the same place, many times and often spreads out over 18 m (60 ft) within the soil around the strike point.

Thunder always accompanies lightning. When lightning occurs, the air through which it travels is instantaneously heated to a temperature more than 28,000°C (50,000°F).

The air expands rapidly due to this heating, then quickly contracts as it cools. It is this contracting shock wave that we hear as thunder.

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

1.19

• 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.

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

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

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

Unfortunately personnel 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.

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

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

Tigercat 6900 Grinder IF YOU ARE CAUGHT OUTSIDE AND HAVE NOWHERE TO GO: • Avoid wide-open areas where you project above the surrounding landscape.

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

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

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

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

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

IF YOU CAN, GET INSIDE:

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

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

IF INSIDE A BUILDING:

• Avoid entering any small enclosures or shelters.

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

• Don’t watch the lightning storm from open windows or doorways. Stay in inner rooms.

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

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

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

IF INSIDE A MOTOR VEHICLE OR FULLY ENCLOSED ROPS EQUIPMENT CAB: • Under no circumstances whatsoever step outside of the vehicle or off the equipment to move to another shelter. Very dangerous electrical pathways to ground may go through you.

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

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

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

• Do not use the telephone except for emergencies.

WHAT TO DO IF YOU FEEL YOUR SKIN TINGLING, YOUR HAIR STANDS ON END, LIGHT METAL OBJECTS VIBRATE OR YOU HEAR A CRACKLING SOUND: • Lightning is probably about to strike. You only have a few seconds to act.

• Put your feet together. Crouch down like in a baseball catcher’s position. Hold your head down.

Cover your ears to protect them against the noise of the thunder.

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

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

1.20

Tigercat 6900 Grinder

Safety

WHAT TO DO IF A CO-WORKER HAS BEEN STRUCK BY LIGHTNING: • The victim does not carry any electrical charge.

There is no danger to anyone helping this person.

You can touch him or her immediately.

• Call your local emergency response telephone number immediately.

• If the victim has no pulse, their heart has stopped or they have stopped breathing, call for professional medical help immediately and then begin administering appropriate first aid. Use a portable defibrillator if one is available (as required).

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

FIRE PREVENTION

Tigercat 6900 Grinder • Steam clean the engine, hydraulic pumps, transmission, brake, fuel and hydraulic oil tank compartments and all machine belly pans at least once each month, or more frequently when working in conditions with high volumes of forest debris • Use only non-flammable solutions for cleaning the machine and components.

When working in a forest environment combustible debris will collect in tight corners of the machine. Left unchecked, this debris may cause a fire; when mixed with fuel, oil, or grease in a hot or confined place, the danger of fire greatly increases.

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

• Maintain a charged fire extinguisher on the machine at all times. Know how to use it.

• Remove dust and debris regularly from the air intake doors, cooling system components, and A/C condenser to prevent engine and hydraulic system overheating and to maintain efficient operation.

Refer to CLEANING COOLER PACKAGE in SECTION 3 .

• Remove all forest debris and fine organic material around engine intake and exhaust components (turbocharger, exhaust manifold, exhaust pipes, muffler) at the end of each shift, or more frequently when working in conditions with high volumes of combustible forest debris. Check carefully in small pockets and cavities around the engine enclosure where smouldering debris may gather.

NOTE: Minor debris accumulations near hot components can ignite and smoulder. Smouldering debris may shift and cause fire to spread.

• Clean out all accumulated forest debris (twigs, needles, branches, bark, leaves, saw dust, wood chips) and any other combustible materials from inside the machine belly pans, lower machine structures, and engine, hydraulic, and fuel system areas no less frequently than at the completion of each work shift.

• Inspect the machine regularly for evidence of diesel fuel or hydraulic system leakage. Check for worn or damaged hydraulic and fuel lines before turning on the engine.

• Clean up any grease, diesel fuel, or oil spillage (hydraulic or lubricating) immediately.

• Inspect the exhaust system daily for evidence of leakage. Check for worn, cracked, broken, or otherwise damaged pipes or muffler, and missing or damaged bolts or clamps. Make repairs immediately. Engine exhaust leaks can cause fires.

Do not operate the machine until exhaust leaks are repaired.

NOTE: Changes or increases in engine exhaust noise levels often indicate exhaust leaks. Do not ignore these warnings. Shut down the machine immediately and complete repairs.

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

• Never leave the machine parked with the boom raised off the ground. Should the hydraulic cylinder hoses burn through in a fire, hydraulic oil will escape and the boom will fall rapidly to the ground.

• Turn OFF the battery disconnect switch when parking the machine.

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

• Remove the ignition key, and lock the cab and fuel cap at the end of shift to reduce the risk of vandalism or theft.

• Do not smoke in the vicinity of the machine.

• Do not smoke during fuelling operations, when the fuel system is open to the atmosphere, or when servicing the batteries. Exercise caution if smoking in the woods.

• After transporting a machine by road, open all doors and access panels; remove any debris that may have settled around the engine and exhaust system during the journey.

• Before undertaking repair work or welding, clean the surrounding area and place a fire extinguisher within easy reach.

• Store rags and other combustible materials safely in a fireproof location.

• Do not operate the machine near burning timber. Do not use the machine to push burning timber into a pile.

• There is no substitute for fire prevention. Time invested in prevention is repaid through productivity on the job site.

1.22

Tigercat 6900 Grinder

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

NOTICE Equipment fires undermine productive logging, may increase your insurance premiums dramatically, or prevent you from obtaining insurance coverage. Make fire prevention a priority.

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

HOW TO PREPARE FOR A MACHINE FIRE • Inspect and maintain all machine systems on a routine basis.

• Maintain fire extinguishers in proper working order. Follow the manufacturer’s instructions for inspection and maintenance (on the label of the fire extinguisher and in the user's manual).

• Verify that any pressurized water systems on the machine are charged and in working order. Refer to PRESSURIZED WATER SYSTEM MAINTENANCE as applicable in SECTION 3.

• Verify the correct types of fire extinguishers are available at the work site. Most fires involving mobile forestry equipment will be Class A or B. Dry chemical extinguishers should be rated ABC and pressurized water extinguishers should be rated A. • Class A fires involve ordinary combustibles such as wood, cloth, paper, rubber and many plastics, • Class B fires occur with flammable liquids such as diesel fuel, oil, and grease.

• Class C fires apply to energized electrical equipment.

• Know how to use the fire extinguisher, the pressurized water system (as applicable), and the fire suppression system (as applicable) on your machine. There is no time to read instructions during a fire emergency. Be prepared to act.

• Keep emergency contact information readily available in case of fire.

IN CASE OF A MACHINE FIRE If a machine fire occurs: 1. Lower all working attachments to the ground.

2. Turn OFF the engine.

3. Activate the fire suppression system as applicable.

4. Radio or call for help. Report a fire immediately.

5. Turn OFF the battery disconnect switch if it safe to do so.

6. Dismount the cab; take the fire extinguisher and pressurized water system hose (if applicable) with you.

7. Put your personal safety and the safety of other persons first. Approach any fire with extreme caution. All fires are potentially very dangerous and life threatening.

Before deciding to fight the fire, be certain that:

• The nozzles on fires extinguishers and pressurized water systems (if applicable) must fit within the fire extinguisher access ports on the machine doors.

• Keep the fire detection system in working order as applicable. Refer to FIRE DETECTION SYSTEM in SECTION 2.

• Keep the fire suppression system charged and in working order as applicable. Refer to FIRE SUPPRESSION SYSTEM in SECTION 2.

• Know the recommended fire procedures in your organization's emergency action plan.

• Follow all national, state/provincial, and local fire fighting regulations. Regulations will vary from region to region but most will require that: • Workers assigned to fire fighting duties must be physically capable of performing them safely and effectively.

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

1.23

1. The fire is small and not rapidly spreading.

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

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

If in doubt about your ability to fight the fire, do not attempt to fight it. Stay well back. Wait for help to arrive.

NOTE: Engine coolant, diesel fuel, or hydraulic hoses may fail during a fire. Hot coolant, fuel, or oil could be ignited, or may spray at high velocity from damaged hoses.

Safety

Tigercat 6900 Grinder

When fighting a fire:

AFTER A MACHINE FIRE

1. If possible, use a dry chemical fire extinguisher or fire suppression system first.

Before returning a machine to operations:

2. 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 debris or hot machine components in the area. Water cools the area, reducing the chances of re-ignition.

3. Use the fire extinguisher PASS method:

1. Determine the cause of the fire.

2. Complete all necessary repairs.

3. Service and recharge the fire suppression and detection systems as applicable.

4. Report the fire to your dealer and/or Tigercat Industries Inc. by completing an incident report (Tigercat form 5101).

Pull the safety pin at the top of the extinguisher that prevents the discharge lever from being pressed.

Break the plastic seal as the pin is pulled.

NOTE: Fire detection systems are offered as optional installations on some Tigercat product lines. Please disregard any references made to fire detection systems if not installed on your machine.

Aim the nozzle at the base of the fire. Do not aim the nozzle at the flames. To put out the fire, the fuel must be extinguished, not the flames. Hose nozzles are often clipped to the extinguisher body. Release the hose before taking aim.

NOTE: Dry and wet chemical fire suppression systems are offered as optional installations on some Tigercat product lines. Please disregard any references made to fire suppression systems if not installed on your machine.

Squeeze the discharge lever to release the pressurized extinguishing agent. The handle can be released at any time to stop the discharge.

Sweep from side to side at the base of the fire until the fire is completely out or the fire extinguisher is empty.

822C-190

Typical Fire Extinguisher Access Port

4. Insert the fire extinguisher nozzle into the appropriate access port and discharge the extinguisher.

5. If it is safe to do so, open the access panels in the area of the fire and aim the extinguisher directly at the base of the flames.

6. If it is impossible to reach an access port or to open a panel or door, discharge the extinguisher through mesh screening or any available opening.

7. Monitor the machine after extinguishing a fire in case of re-ignition; remain until help arrives.

DRY CHEMICAL CLEANUP PROCEDURES

WET CHEMICAL CLEANUP PROCEDURES

ABC dry chemical fire extinguishers and fire suppression systems discharge a chemical powder. The powder comprises very fine particles that penetrate and cover all components in the vicinity of the discharge.

The wet chemical suppression fluid contains frost protection, rust inhibitor, and film-forming liquids that are broken down by natural organisms. When the fluid dries, the corrosion protection loses its effect. Clean up wet chemical discharges as soon as possible to avoid corrosion on metal parts.

Areas in contact with dry chemical power must be neutralized and cleaned after a fire. Wear protective clothing, safety goggles, and a fine particle dust mask.

1. De-energize electrical systems prior to any cleanup.

2. In areas that remained cool and dry during the fire, the dry chemical remains in powder form.

Clean these areas immediately to prevent residual powder from coming into contact with water or ambient moisture.

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.

Wipe all surfaces with a damp cloth.

3. In areas exposed to moisture during the fire, the dry chemical powder combines with water to form a paste that is mildly acidic. All surfaces covered in dry chemical paste, including electrical contacts, are vulnerable to corrosion.

Neutralize the acidic paste on large surfaces by spraying or washing 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.

Clean electrical contacts with a contact cleaner that has no flash or fire point and is non-corrosive and non-conductive, such as CRC Contact Cleaner 2000.

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

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

When exposed to moisture the caked dry chemical is also mildly acidic. When the breakdown procedure has been completed, follow this immediately with the neutralizing procedure as described in step 3.

1.25

If the suppression fluid is sucked into the engine air intake, it will not significantly change engine functioning.

However, starting difficulties may occur with diesel engines because the suppression fluid contains water.

The suppression fluid also may cause corrosion damage if the engine is not cleaned soon after a fire.

Clean affected areas promptly to protect electrical system functions and prevent short circuits.

To clean affected areas: 1. Flush the affected area with pressurized fresh water.

2. Use an alkaline washing detergent to remove the film. (Film residue attracts dirt and other impurities on affected surfaces.)

3. Flush affected areas a second time to remove detergent residue.

NOTICE To protect engines, electrical installations, and other metal parts against corrosion, flush the remains of dried or moist suppression fluid as soon as possible after the release of the piston accumulator (use a high pressure washer if possible).

Tigercat 6900 Grinder STOPPING THE ENGINE

IMPORTANT! Stopping the engine immediately after it has been working under load can result in overheating and premature wear of the engine components. Follow the stopping procedure outlined below to allow the engine to cool. The important benefits are: • Extended life of engine, cooling and exhaust systems.

• Reduced risk of post shutdown fires.

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

1. Turn all machine functions OFF. 2. Set engine speed at LOW and run the engine at LOW for three minutes minimum to dissipate heat and reduce the turbocharger speed. This will also prevent loss of coolant by after boil and possible hot spot damage to the engine.

Do not increase engine speed before turning it off.

3. Turn OFF the engine.

4. Remove the ignition key.

5. Turn OFF the battery disconnect switch if required by the servicing procedure or if the machine is to be parked for an extended period of time, such as overnight.

6. Perform EVERY 8 HOURS maintenance at the end of the shift (greasing, clean engine compartment, etc.). This allows the machine time to cool down while under the watchful eye of the operator.

TRACK OPERATION AND WEAR PREVENTION

MAKE GRADUAL TURNS INSTEAD OF COUNTER-ROTATIONS

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.

INSPECT THE UNDERCARRIAGE BEFORE YOU START WORKING In addition to ensuring the undercarriage is clean, spend a couple of minutes on a visual inspection. Check for loose bolts, leaky seals and abnormal wear patterns.

When you spot potential problems early, you can often prevent them from turning into bigger issues that reduce component life significantly or cause expensive unscheduled downtime.

DON'T SPIN THE TRACKS

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.

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.

EXTENDED MACHINE TRAVEL Avoid machine travel over distances of 1 km (0.60 miles) or greater. Extended travel, especially in warm weather, risks overheating the track rollers and burning the oil inside the roller assemblies. The rollers on new machines are especially vulnerable to overheating. (The break-in period for rollers is approximately 200 hours.)

If it is absolutely necessary to drive the machine over an extended distance, observe the following essential precautions:

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.

1. Stop the machine frequently.

2. At each stop, use a suitable hand-held temperature sensor to measure the surface temperatures of the rollers.

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

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

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

2.75

3. If any roller surface temperature reaches or exceeds 80°C (175°F), pause for at least 30 minutes to permit cooling.

Completing just one extended travel without suitable precautions can ruin the oil inside the roller assemblies and cause roller failure. Replace rollers immediately in the event of failure. Operating the machine with failed rollers places excessive strain on other drive train components.

Controls and Operation

Tigercat 6900 Grinder

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

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

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

Maintenance discipline plays a big role in undercarriage component life. One of the most critical maintenance practices is track adjustment. Tight track is the numberone track killer. But whether your track is too loose or too tight, improper adjustment accelerates wear which can increase downtime and repair costs. Follow the manufacturer's recommendations for track adjustment, and perform the adjustment in the machine's working environment. A second important maintenance process is cleaning the undercarriage. To maximize wear life, remove mud and debris at the end of every shift, or more frequently if necessary.

Talk to the experts: Undercarriage components are expensive! To get long life and maximum value from your investment, consult with a dealer or factory rep that really knows the undercarriage business. Ask for advice on operating techniques. Explore relevant application, material and terrain issues. Fine-tune your maintenance processes.

Working together with an undercarriage expert, you can manage your equipment investment over the long term.

TIGERCAT FLUID ANALYSIS PROGRAM

TIGERCAT FLUID ANALYSIS KITS

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

Each kit includes a Prepaid Sample Bottle and Sample Information Form. Preprinted mailing labels are also included to ensure all samples are quickly returned directly to the lab for immediate analysis and results within 24 hours of receipt.

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

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

• Monitoring maintenance schedules and practices and confirming the required maintenance is being done on time.

The same type of sample bottle can be used for all types of fluid testing including Hydraulic Circuits, Final Drives, Axles, Gearboxes, Engines, etc.

To ensure accurate and meaningful results are obtained, each kit also includes detailed instructions on how to properly collect, prepare and ship the fluid samples.

Contact your Tigercat Dealer Parts Department to order kits.

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

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

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

Tigercat Fluid Analysis Kits are available from your Tigercat dealer parts department. If required, arrangements can also be made with your Tigercat dealer to supply and perform all of the required follow-up fluid samples.

HYDRAULIC OIL SAMPLES

FLUID SAMPLE COLLECTION PROCEDURES

A

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

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

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

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

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

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

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

6000174

A Hydraulic Oil Sample Valve – On Hydraulic Oil Return Manifold

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

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

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

PTO AND GEARBOX SAMPLES: • These samples can be taken during the oil change process.

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

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

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

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

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

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

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

GENERAL

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

CAUTION

• Clean away all branches, bark and chips. Clean up all traces of oil to avoid fires.

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

• 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. Repair all exhaust leaks or defective parts immediately. Engine exhaust leaks can cause fires. Do not operate the machine until the exhaust leak is repaired.

• Clean around fill caps before checking or adding fluids.

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

• 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. When exhaust leaks occur during operation, shut down the machine immediately and do not put it back to work until the necessary repairs have been completed.

• Clean up spills as soon as possible.

• Use clean oil and containers.

• Drain dirty oil while still warm.

• Do not exceed recommended fluid levels.

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

• Keep a fire extinguisher on hand at all times.

• Install door safety struts when working on the machine.

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

• Check and clean fire suppression system sensors on a regular basis.

FIRE PREVENTION

FIRE EXTINGUISHER

Proper maintenance of your machine will greatly extend its life and reduce your operating costs.

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

A

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

1. When allowed to accumulate, forest debris and fine organic material (twigs, pine needles, branches, bark, leaves, sawdust, small wood chips, etc.) and any other combustible materials form a fuel source that is extremely difficult to extinguish when ignited. 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.

2. Pay close attention to wiring and plumbing routes during maintenance. ALL wiring harnesses and hydraulic hoses must be properly restrained and clamped to prevent damage from chaffing.

3. If equipped, read the fire suppression system manual and have the system serviced regularly by qualified personnel.

4. In case of fire, turn OFF the engine before discharging the fire suppression system.

Refer to FIRE PREVENTION in SECTION 1 for additional information.

HYDRAULIC SYSTEM NOTICE

Tigercat 6900 Grinder IMPORTANT! Before servicing the hydraulic system, park the machine on level ground. Refer to PARKING THE MACHINE in SECTION 1.

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

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

Use of filters other than genuine Tigercat replacement filters is not recommended. Replace filters at the recommended time intervals.

Refer to SCHEDULED MAINTENANCE in THIS SECTION.

WARNING

Hot fluids and hot machine surfaces can cause serious burns!

• Before servicing the machine, allow the engine cooling system, fuel system, exhaust system, hydraulic system and machine surfaces to cool down.

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

ENGINE FILTERS – REMOVE AND REPLACE

IMPORTANT! Failure to service and replace engine filters at the proper intervals specified in the ENGINE OPERATION AND MAINTENANCE MANUAL, could cause damage to the machine and result in the product warranty becoming NULL and VOID. Check the Tigercat parts catalog for replacement filters.

FUEL FILTERS These engines 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 SCHEDULED MAINTENANCE in THIS SECTION. Operating the machine with a clogged fuel filter will result in low engine power. It is also recommended to drain the fuel filter/ water separator bowl daily.

NOTICE

Refer to the ENGINE OPERATION AND MAINTENANCE MANUAL for the oil and fuel filter replacement procedure. Read and understand the SAFETY section in each of THESE MANUALS.

ENGINE OIL FILTERS

A

6000172

A Engine Oil Filters

The engine oil filters are remotely located in the engine/ hydraulic compartment service platform, on the drive side of the machine.

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

Tigercat does not recommend the pre-filling of spin-on filters due to the risk of damage to the fuel system caused by unfiltered fuel. Unfiltered fuel used to pre-fill filters enters directly into the fuel circuit. Contaminants in unfiltered fuel can cause significant and costly damage to fuel system components. The cleanliness of fuel cannot be guaranteed unless it is pre-filtered before use.

Use of filters other than genuine Tigercat replacement filters is not recommended. Replace filters at the recommended time intervals.

Refer to SCHEDULED MAINTENANCE in THIS SECTION. To prolong the operating life of the fuel filter, the fuel supply storage tank must be clean and free of water and the fuel must be pre-filtered prior to adding it to the machine.

For service and replacement intervals refer to SERVICE AND LUBRICATION POINTS in THIS SECTION. Refer also to ENGINE OPERATION AND MAINTENANCE MANUAL for more detailed information.

C

ENGINE AIR PRECLEANERS

D A B A E

480-017

A B C D E

Dirty Air Specially-designed Vanes Stainless Steel One Piece Impeller Foreign Particles Cleaned Air

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

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

6000148

A Engine Air Precleaners

The engine air precleaners clean engine air before it reaches the air cleaner filter elements. It removes contaminants such as dust, powder, insects, rain and snow. This precleaner is self powered and self cleaning requiring virtually no maintenance.

IMPORTANT! Check the precleaner every 8 hours for foreign materials that may have plugged the intake area or the discharge louvre area. Clean as required.

A plugged precleaner will create a restriction to airflow, resulting in reduced engine performance and increased fuel consumption.

If the machine is operated with a plugged precleaner, excessive air intake restriction will damage the air intake tube which will lead to ingestion of dirt into the engine resulting in engine failure. The air intake filter restriction indicator may not function properly if the air intake tube is damaged.

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

4. The centrifugal force of the tornado expels the heavier than air dirt particles (D), chaff, dust, snow, rain, etc., out the discharge louvre.

5. Cleaned air (E) enters the engine air cleaner intake pipe, and the filter element has only the very light particles to remove.

AIR INTAKE TUBING AND JOINTS Check all air intake system components, rubber elbows, connector hoses, tubes and clamps every eight hours for damage, hardening, wear, cracks, leaks, loose clamps or loose hanger bracket hardware and repair or replace immediately.

Replace all air intake rubber components such as elbows and connectors every 2000 hours. High temperatures in this area can cause the rubber to harden.

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

Tigercat 6900 Grinder

AIR CLEANERS A

In addition to the SCHEDULED MAINTENANCE in THIS SECTION, the following instructions should also be noted: NOTE: Replace secondary (safety) filter every third primary filter change.

The most common and most damaging air intake servicing problems are over servicing and improper servicing.

OVER SERVICING Filter elements increase in dust cleaning efficiency as dust builds up on the media. Looks can be deceiving. A filter that is 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 the engine manufacturer’s guidelines, should be replaced.

IMPROPER SERVICING Engine exposure to dust during servicing is the largest single factor contributing to engine damage due to dust. Abrasive dust can easily enter the intake system once the air cleaner element has been removed for replacement. The safety element reduces the risk, however it must also be replaced at every third primary element change.

6000149

A Air Cleaners

B

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

2. Avoid dislodging dust from filter element(s) by gently pulling the element out of the housing.

3. Check your old filter sealing surfaces, This will help detect foreign material on the sealing surface that is causing leakage.

A 726D-006

A Primary Element B Secondary (Safety) Element

NOTE: Do not clean and reuse filter elements.

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.

4. Clean the inside of the housing.

5. Clean the sealing surface before inserting a new filter element.

6. Inspect the new filter for damage.

The air cleaners on this machine use two filter elements; a primary element and a secondary (safety) element.

7. Insert the new filter properly. Apply pressure to the filter frame not the pleated filter surface.

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

8. Check connections hoses and tubes for an air tight fit. All clamps, bolts and connections must be tight.

Check rubber elbows for splits or wear points. Leaks in these locations send dust directly to the engine.

Check the rubber air cleaner unloader valve on the air cleaner housing every 8 hours. If this valve is missing, damaged or has become hard, it will cause the air cleaner to become ineffective.

Replace the unloader valve every 1000 hours.

Remove the unloader valve from the tube of the air cleaner housing. A good valve should be soft and flexible. Check and clean the valve. If it is plugged, check the filter elements as they may also need to be replaced. Reattach the valve to the tube. The valve should suck closed at about one-third of HIGH engine speed. When operating in high dust conditions this valve should be checked and squeezed every two hours to release dust buildup.

PRESSURE WASHING

PRESSURE WASHING PROCEDURE

Pressure washing is one of the easiest and most economical ways to preserve your investment.

Accumulated mud can damage track rollers, sand will grind down pins and bearings and wood debris buildup in machine enclosures is a serious fire hazard. Pressure washing is also good practice before and after servicing equipment.

CAUTION To avoid slips, trips or falls, all handles, steps and platforms must be kept free of grease, oil, fuel, mud, snow, ice, and forest debris.

IMPORTANT! Allow the engine to cool down before pressure washing the engine compartment. Pressure washing a hot engine with cold water could crack the engine block or other components.

To avoid damaging sensitive machine components, do not allow water to come in contact with electrical/ electronic components or air ducts and filters inside the vehicle.

Due to the sensitive electronics on this machine use only warm water, a mild detergent and a gentle pressure wash setting.

1. Start the engine. Maintain engine speed at LOW.

CAUTION

2. Set machine angle fully towards the feed conveyor.

Refer to OPERATING THE MACHINE – SETTING MACHINE OPERATING ANGLE in SECTION 2.

3. Clean the undercarriage and tracks with a shovel and a broom to remove all debris before pressure washing.

4. Pressure wash the tracks and undercarriage.

5. Set machine angle fully towards the discharge conveyor. Refer to OPERATING THE MACHINE – SETTING MACHINE OPERATING ANGLE in SECTION 2.

Use personal protective equipment to guard against flying debris.

IMPORTANT! Use a high volume, low pressure fan nozzle or nozzle setting for all equipment cleaning. High pressure spray can damage paint, penetrate electrical connections and remove labels. Use a mild detergent and make sure pressure settings are below 83 bar (1200 psi).

3. Use compressed air or water for cleaning.

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

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

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

A Hydraulic Oil Cooler Frame B Fan C Fan Motor

The hydraulic oil cooler with motor-driven fan is located on the drive side of the machine.

In normal operation, the fan draws air from outside of the machine through the hydraulic oil cooler.

Avoid the risk of fire caused by debris accumulating on surfaces that may become hot during machine operation. Use care when cleaning to ensure debris removed from one area of the machine does not accumulate on other areas of the machine.

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

Pay particular attention to cleaning in the corners of the cooler as these areas usually plug deeply. For more information on fire prevention refer to FIRE PREVENTION in SECTION 1.

If an oil leak occurs in this area it should be thoroughly power-washed with a mild soap to ensure all of the oil is removed. The presence of oil causes dust and dirt to cling to surfaces which will impair the ability of the fans to remove dust and dirt particles.

IMPORTANT TRACK DRIVE NOTES NEW MACHINE

A

Set track sag correctly before driving a new machine.

Track sag may be factory set at less than the specified value for shipping purposes. It must be adjusted before beginning operations.

During the initial operating period, frequent track sag adjustments are necessary.

B

TRACK SAG Inspect track sag often. Maintaining correct track sag increases track assembly life by as much as 50%. A track that is set too tight will wear out prematurely due to excessive chain tension.

400487

MEASURING TRACK SAG

A No Sag – Track Too Tight B Too Much Sag – Track Too Loose C Sag 40 mm (1.57) – Track Correct

1. Park the machine on level ground. Refer to PARKING THE MACHINE in SECTION 1.

2. Place a 1.2 m (4 ft) straight edge on top the track over two rollers as shown.

B

A

C

4. The measured dimension must be 50 mm (1.97 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 TRACKS – TRACK SAG ADJUSTMENT in THIS SECTION for the track chain tension adjustment procedure.

5. Repeat this procedure for the opposite track.

WARNING

2. Connect a grease gun to the grease fitting on the coupler.

Hydraulic oils or grease under pressure can penetrate the skin and could result in death or serious injury.

3. Add grease until the track sag dimension is within recommended limits.

Refer to TRACKS – MEASURING TRACK SAG in THIS SECTION for recommended limits.

CAUTION

4. Remove the grease gun from the coupler fitting.

5. Store the valve coupler in a safe place.

Do not remove the fill valve. The grease in the idler is under very high pressure.

LOOSEN TRACK 1. Slowly loosen the fill valve until grease begins to escape through the vent passage in the valve body housing.

Grease will vent around the valve body threads.

Remove grease until the track sag dimension is within recommended limits.

Refer to TRACKS – MEASURING TRACK SAG in THIS SECTION for recommended limits.

TORQUING UNDERCARRIAGE BOLTS

TRACK SHOE RETAINING BOLTS

It is important to check the torque values of the master track shoe retaining bolts, track shoe retaining bolts, and the top and bottom roller retaining bolts at the NEW MACHINE MAINTENANCE time period (first 125 hours) and then every 125 hours. Refer to SCHEDULED MAINTENANCE – EVERY 125 HOURS in SECTION 3.

When installing new components, all traces of paint and dirt must be removed from all mating surfaces including the contact area under the bolt head and nut.

Both the bolt and the nut on the track shoes should be lightly lubricated with SAE 30 oil and tightened using the torque-turn method.

The torque-turn method involves torquing the bolt to an initial predetermined value, plus an additional ⅓ turn (not the value shown in the torque charts) to ensure a more accurate and consistent torquing of the bolts, with less likelihood of the bolt/nut coming loose later.

When checking the torque values at the first 125 hours and every 125 hours thereafter use the CHECKING TORQUE values listed in the following paragraphs.

860C-333

Torque Procedure

Track shoes must be fastened together applying the exact torque values and using the torque-turn method described in TORQUE CHART, SPECIFIC in SECTION 3.

Track shoe bolts and nuts are designed specifically for this purpose and should not be substituted with standard off the shelf hardware.

Once checked, they should be removed, surfaces cleaned, and reused using the torque-turn method. If the shoe is not loose but a single bolt is low on torque, loosen the bolt and repeat the torque-turn method.

CAUTION The torque-turn method involves torquing the bolt to an initial predetermined value, plus an additional ⅓ turn (not the value shown in the torque charts) to ensure a more accurate and consistent torquing of the bolts, with less likelihood of the bolt/nut coming loose later.

If loose or under torqued bolts are discovered any time after the 125 hour check, the bolts and nuts must be replaced with new ones, surfaces cleaned, and repeat the torque-turn method.

Only bolts with grade 12.9 or 170 designation forged in the head are approved.

When checking the torque values at the first 100 hours and every 125 hours thereafter use the checking torque values.

Refer to SECTION 11 of the SERVICE MANUAL for torquing procedure and torque values.

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