STANDARDS FOR MACHINE OPERATOR PROTECTIVE STRUCTURES.....................................................vii

Tigercat 470 Mulcher

Introduction

STANDARDS FOR MACHINE OPERATOR PROTECTIVE STRUCTURES THIS OPERATOR ENCLOSURE MEETS THE FOLLOWING STANDARDS: • ISO 8082-1:2009 ROLL OVER PROTECTION STRUCTURES (ROPS) • ISO 8083:2006 FALLING OBJECTS PROTECTION STRUCTURES (FOPS) • ISO 8084:2003 OPERATOR PROTECTION STRUCTURES (OPS)

MODIFICATIONS AND REPAIRS The integrity of the ROPS, 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 the certification of approval of the ROPS, FOPS, OPS structure will become void if any such modifications take place.

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

Both of the above are provided 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, FOPS, OPS standards so they will withstand force and absorb energy during a roll over (ROPS), 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, 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.

This label is affixed to one of the following areas of the engine: the top of engine’s rocker arm cover, the right-hand side of the oil pan, and the right-hand side of the engine front gear cover.

The warranty period begins on the date the new equipment is sold to the first retail purchaser. The presence of the emission control label is the indication that the engine conforms to the applicable standards. Any emission control system parts which are proven defective during normal use will be repaired or replaced during the warranty period.

The engine owner has responsibility to perform all the required maintenance listed in the Operation and Maintenance Manual. Tigercat will not deny an emission warranty claim solely because no record of maintenance exists; however, a claim may be denied if failure to perform maintenance resulted in the failure of a warranted part.

It is recommended that replacement parts used for maintenance or repairs be Tigercat Service Parts to maintain the quality originally designed into your emission certified engine. The use of non- Tigercat parts does not invalidate the warranty on other components unless the use of such parts causes damage to warranted parts.

The manufacturer is liable for damages to other engine components caused by the failure of any warranted emission control system part. Tigercat is not responsible for failures resulting from improper repair or the use of parts that are not genuine Tigercat or Tigercat approved parts.

Component coverage New engines certified for sale and registered will have the following items covered by the emission warranty, depending on the emission level of the engine, if the items were first installed on the new engine as original equipment: Fuel injection system

• Fuel injection pump • Fuel injectors • Fuel injection lines Air induction system

Safety

WORKING WITH OIL

SAFETY HAZARDS – VITON SEALS

Direct contact with oil implies a risk of skin complaints such as eczema. Strict hygiene should be observed.

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

Some advice which should be observed: • 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.

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

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

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

• 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!

• Do not put oily rags in your pockets.

• 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.

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

• 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.

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

• Avoid breathing in oil fumes.

• 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.

1.7

Safety

Tigercat 470 Mulcher

MULCHING OPERATION SAFETY

DANGER ZONES

• Land clearing operations generally involve other machinery and people on the site. Operators must maintain an awareness of all working traffic within 150 m (500 ft) of the mulching operation.

A

B

• Pieces of wood, debris from the ground and even cutting tools separating from the rotor become potentially dangerous projectiles when thrown from these machines.

• Inspect rotor teeth, tooth retaining bolts, rotor, wear liner and shear bars.

480-004

A Front Danger Zone B Rear Danger Zone

• All tooth retaining bolts must be tightened snugly Avoid overtightening.

• Danger exists most prominently to the rear and front of the mulching head.

• Replace all worn rotor teeth.

• Operate so the main discharge areas of the mulching head are not directed at people, livestock, buildings or other machines.

• Replace the retaining bolt when replacing a rotor tooth.

• Inspect the rotor for weld cracks and other damage.

• Throw distance for metal pieces and stones can be many times the distance for wood chips.

• Check the rotor does not wobble due to worn shaft bearings.

• Danger is greater if the site contains stones or abandoned metal.

• Never operate the mulching head if the rotor has missing teeth, tooth fasteners or has a damaged rotor.

• Poor maintenance increases the danger. Thorough timely inspection and replacement of worn rotor, rotor teeth, fasteners and wear plates. Heed warning signs of missing parts or sounds of striking rocks and adjust operation to suit the site.

• Shut down the mulching head immediately if you feel excessive vibration when the rotor is running.

• Check the mulching head housing is clear and undamaged.

• Do not operate mulching head with missing access covers.

DANGER The safety of persons around the machine and mulching head is the responsibility of the machine operator.

Danger caused by flying debris, improper operation of the mulching head and failure to follow safety precautions can result in personal injury.

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

Chunks of wood and rock can be thrown from the front and rear of the mulching head. This occurs when the mulching head is raised high enough to allow debris to escape the guard chains at the rear or when the mulch door (if equipped) is not closed when pull-working. No one should be allowed within the HAZARD ZONE. This condition is dangerous, refer to HAZARD ZONE in THIS SECTION. The following precautions should be followed: • Never allow anyone to remain at the front or rear of the machine while it is in operation.

• Inspect daily for damaged or missing belt covers.

Replace covers before operating.

• Be especially careful when the rotor is lowered onto new material and when the rotor is raised up and out of material it has been working.

CAUTION Do not operate the mulching head without the debris door.

1.13

Safety

Tigercat 470 Mulcher

URBAN PRECAUTIONS

AVOID FENCES • Do not drive the mulcher into fences, especially chain link fences. Chain link fencing can damage the rotor.

Increased safety precautions are required when working: • Near streets.

• Near highways.

• When operating mulching head properly position head for push working and pull working for safety and improved operation.

• In parks, on golf courses or other inhabited areas.

• Near buildings.

• When tree toppling, know and control the direction a tree will fall to prevent injury to co-workers or damage other vehicles.

ESTABLISH SAFETY PARAMETERS THAT FIT THE SITE • String coloured warning tape to cordon off the area.

NOTICE

• Use a traffic director when the hazard zone impinges on pedestrian or vehicular traffic.

To prevent component damage, have the debris door open when preparing to fell standing trees.

• Erect barriers.

ASSESSING THE POTENTIAL DANGERS OF THE JOB SITE

• Work within your operating skills, do not attempt to cut down a tree that is too large to handle.

Before working in a new area a visual survey of the area to be worked is helpful in identifying undesirable materials which may be present. Remove as much of the undesirable materials as is practical before proceeding.

• When pull working (moving in reverse), watch for obstacles in your path.

AVOID METAL AND WIRE

• Travel with mulching head as close to the ground as possible, never elevate the mulching head unless necessary.

• Never use this machine to clear an area when other equipment and operator's are also moving in.

Preplan to work the area in advance before other equipment arrives.

• Metal can break rotor teeth and create a projectile hazard.

• Wire wraps itself around the rotor shaft especially near the bearings. This can cause wire to enter past the grease seals and cause damage to bearings if it is not removed promptly.

• Never work alone. Regularly inform other crew members of your intentions, location and length of time to perform duties.

USE CAUTION WITH STRINGY VEGETATION

• Stop the mulching head rotor before leaving the mulching area.

Shredding materials like Palmetto, Bird of Paradise, and yard waste tied with plastic should be approached with caution. Stringy vegetation and plastic ties gravitate toward the bearings. The operator should exercise caution while working with this type of material.

NOTE: The rotor may continue to free wheel for several minutes after the rotor switch has been turned OFF. • To stop the mulching head rotor from rotating, carefully lower the rotor onto a stump. This should be done gently to prevent unnecessary loading of the rotor, housing and bearings.

AVOID PLASTICS • Hoses, bags, tarps and ropes must be removed as soon as they are seen.

• Mattresses, rugs, clothes and cloth will plug the machine immediately.

• Inspect the rotor for clinging strands often.

ANIMAL REMAINS Animal remains such as calf and deer carcasses will plug the machine due to their leathery skin. Avoid the unpleasant task of removing the remains from the rotor.

FLUID INJECTION INJURY

Safety IN THE EVENT OF ANY SUSPECTED 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.

• REPORT THE INJURY TO YOUR SUPERVISOR IMMEDIATELY. • SEEK PROFESSIONAL MEDICAL ATTENTION IMMEDIATELY. The best defence against suffering the effects of fluid injection is to prevent the accident from occurring in the first place.

SEARCHING FOR POSSIBLE FLUID LEAKS: • Do not search for leaks with your bare hands. Wear thick protective gloves.

• Wear safety goggles for eye protection.

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

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.

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

• Place the end of a long piece of wood in the suspected path of any fluid stream. Do not use any part of your body.

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

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

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.

• Do not grab any hydraulic or diesel fuel connectors or hoses when they are subjected to pressure.

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

• Do not use any hoses that you suspect could be defective.

1.23

Safety

Tigercat 470 Mulcher

GREASE INJECTION INJURY WHEN USING PNEUMATIC GREASE GUNS Pneumatic grease guns can deliver grease at pressures from 17 – 400 bar (246 – 5801 psi). It takes less than 7 bar (100 psi) to inject a substance through human skin.

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

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

The amount of fluid injected, type of fluid (or material), pressure at which it was injected, and the elapsed time between injection and 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: • All operators of high pressure pneumatic grease guns MUST be trained in the hazards of its operations and the treatment for such injuries.

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

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

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

• Install protective shrouds 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

LIGHTNING SAFETY

WHAT 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.

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: • 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 • 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 miles). Lightning travels both in front of and behind a thunderstorm and so strikes happen even when rain has not started or has stopped. Lightning can hit in the same place, many times and often spreads out over 18 m (60 feet) within the soil around the strike point.

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

Thunder 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.

• 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 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.

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.

1.25

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.

Tigercat 470 Mulcher 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 fibreglass 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.

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

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

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

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

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

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

Note the rubber tires on motor vehicles and heavy equipment do not increase safety from lightning strikes.

Lightning has already travelled a great distance through the air to strike the vehicle. In comparison a few inches of rubber in a tire offers absolutely no additional insulation.

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

• Avoid entering any small enclosures or shelters.

IF INSIDE A BUILDING:

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

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

• 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.

• Do not use the telephone except for emergencies.

1.26

Tigercat 470 Mulcher

Safety

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.

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

• 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.

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

However, when mixed with fuel, oil or grease in a hot or confined place, the danger of fire is greatly increased.

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

The following guidelines will help to keep your equipment up and running efficiently and keep the risk of fire to a minimum: • Maintain a CHARGED fire extinguisher on the machine at all times and KNOW HOW TO USE IT. • Remove debris and blow out dust regularly from the air intake doors, engine radiator and charge air cooler, hydraulic oil cooler, diesel fuel cooler and air conditioning condenser core to prevent overheating of the engine and hydraulics and to maintain efficient operation of the machine. Refer to CLEANING COOLER PACKAGE in SECTION 3.

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

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

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

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

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

Do not operate the machine until the exhaust leak is repaired.

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

• Blow off all forest debris and fine organic material accumulated near hot engine exhaust components (turbocharger and exhaust manifold as well as exhaust pipes and muffler) at the completion of each work shift or more frequently when working in logging conditions where large amounts of combustible forest debris are present.

Visual inspection after blow off to ensure thorough cleanliness is vital. Engine exhaust systems provide numerous small pockets where saw dust, small wood chips and other flammable forest debris can gather. Even small accumulations close to hot exhaust components can ignite and smoulder. If dislodged this smouldering debris can fall into other areas of the machine and thereby spread a fire.

• 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 boom, arch or blade suspended off the ground. Should their supporting hydraulic hoses burn through during a fire, pressurized hydraulic oil may be injected into the fire and the boom, arch or blade will fall rapidly to the ground.

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

1.28

Tigercat 470 Mulcher • Remain with the machine for at least 45 minutes at the end of operations while the machine cools.

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

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

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

• All hand held fire extinguishers must be charged and in working order. Fire extinguishers require routine care. Follow the manufacturer’s instructions for inspection and maintenance shown on the label of the fire extinguisher and in the FIRE EXTINGUISHER MANUFACTURER'S DOCUMENTATION. • Any pressurized water systems on the machine (if applicable) must be charged and in working order. Refer to PRESSURIZED WATER SYSTEM MAINTENANCE in SECTION 3.

• You must have the proper fire extinguishers on site.

Most fires involving mobile forestry equipment will be Class A or B. Dry chemical extinguishers must be rated ABC and pressurized water extinguishers must 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 and Class C fires apply to energized electrical equipment.

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

• 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.

• The fire detection system* must be in working order.

Refer to FIRE DETECTION SYSTEM in SECTION 2.

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

• The fire suppression system** must be charged and in working order. Refer to FIRE SUPPRESSION SYSTEM (OPTIONAL) in SECTION 2.

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

• You must be familiar with the recommended procedures for fire contained in the emergency action plan of your company.

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

• You must follow all national, state/provincial and local regulations dealing with fire fighting in effect in your specific geographic region. Regulations will vary from region to region but most will usually require:

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

• 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.

1.29

Safety

Tigercat 470 Mulcher

• When 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.

6. If possible use a dry chemical fire extinguisher or fire suppression system** 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.

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

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

• Use the PASS method. This is the most effective use of a fire extinguisher.

• Pull the pin at the top of the extinguisher that keeps the handle from being pressed. Break the plastic seal as the pin is pulled.

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

• Aim the nozzle at the base of the fire. Do not aim the nozzle at the flames. In order to put out the fire, you must extinguish the fuel, not the flames. Hose nozzles are often clipped to the extinguisher body. Release the hose before taking aim.

WHAT TO DO WHEN A MACHINE FIRE OCCURS

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

If operating the machine when a fire occurs: 1. Lower all working attachments to the ground.

2. Turn OFF the engine.

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

3. Activate the fire suppression system**.

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

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

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

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

Before deciding to fight the fire, be certain that: 1. The fire is small and not rapidly spreading.

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

700068

Typical Fire Extinguisher Access Hole

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

• Place the nozzle of the fire extinguisher into the appropriate fire extinguisher access hole and discharge the extinguisher.

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.

• 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.

5. Be aware, hoses containing 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.

1.30

Tigercat 470 Mulcher

Safety

• Ensure the machine and all components have cooled down sufficiently after a fire to prevent re-ignition from occurring.

• Remain with the machine until help arrives.

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

• 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.

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

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

NOTE: All surfaces covered by this dry chemical paste including electrical contacts are vulnerable to corrosive attack.

3. Replace or recharge all extinguishers used in fighting the fire.

To neutralize the acidic paste on large surfaces, spray or wash these areas with a mixture of three parts hot water to one part baking soda. Allow this mixture to stand for several minutes before rinsing with warm water. Wash the area with a mild soap and water solution. Rinse thoroughly with water.

Blow-dry to remove all residual water. Cleaning electrical contacts with an electrical contact cleaner that has no flash or fire point and is non-corrosive and non-conductive such as CRC Contact Cleaner 2000.

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

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

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

The following are recommendations for the cleanup and neutralizing of areas exposed to dry chemical powder: NOTE: Workers performing this work must wear protective clothing, safety goggles and a fine particle dust mask to minimize their personal exposure to the dry chemical powder.

• All electrical systems must be completely deenergized prior to any cleanup.

1.31

• In areas exposed to heat during the fire, the dry chemical powder will melt forming a coating that cakes or crusts on all surfaces. To break down the caked dry chemical, spray or wash these areas with a 50/50 mixture of hot water and Isopropyl alcohol.

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

Safety

Tigercat 470 Mulcher

WET CHEMICAL CLEANUP PROCEDURE The 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. In order to avoid corrosion on metal parts, cleaning must be performed as soon as possible. This is done by flushing with fresh water, preferably under high pressure. Also use some form of alkaline washing detergent that facilitates the removal of film formation. Otherwise a coating can remain which collects impurities.

If the suppression fluid is sucked into the air intake on the engine, it will not significantly change the function of the engine. However, starting difficulties can occur with diesel engines since the incoming suppression fluid contains water. The suppression fluid can cause corrosion damage if the engine is not cleaned within a short time after the fire. The function of the electrical system can be affected by the suppression fluid and give undesirable short circuits if cleaning is not performed promptly.

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).

The fire suppression system uses a dry chemical powder which is stored in a 23 kg (50 lb) pressurized cylinder.

It is discharged through 6 nozzles strategically placed in the engine compartment and hydraulic areas. The discharge is activated either automatically by the fire detection thermostats or manually by the operator.

The machine leaves the factory with the AMEREX fire suppression system fully deactivated to prevent accidental discharge. The in-line fuse for the power lead wire to the battery (in the battery compartment) is removed and the nitrogen bottle is not installed.

The control panel mounted in the cab provides continuous monitoring of the system. It also, automatically actuates the suppression system when signalled by the thermostats.

When the panel is plugged into an operational configuration the system will illuminate the green 'System OK' LED.

Tigercat 470 Mulcher

Controls and Operation

DISCHARGE OF THE SYSTEM A fire will initiate an electrical signal (automatic or manual) is at the control panel. The control panel 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 into the discharge area protected by the system. The control panel also turns OFF the engine and all electrical power automatically when the fire suppression system is discharged.

The system will activate the discharge system and the automatic engine shutdown system. There will be a cloud of dry chemical dispersed in the discharge area.

The engine will automatically, and immediately,turn OFF. IMPORTANT! Turn OFF the engine before discharging the system.

This will keep the dry chemical in the engine area.

• Get away from the machine. If possible and safe to do so, take the portable fire extinguisher located in the cab on the entry side.

• Stand by with a portable fire extinguisher and watch for any flashbacks after the system has discharged.

NOTE: The engine does not turn OFF 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 the engine manually.

• Do not restart the machine until it has been serviced and cleaned.

• Do not return the machine to service until the source of the fire has been located and neutralized.

IN CASE OF FIRE: A

B

• The fire suppression system must be recharged by Amerex Factory Certified Personnel before returning the machine to service.

C

• Before cleaning up after a discharge, read the AMEREX manual. If water mixes with the dry chemical it becomes corrosive and can seriously damage wiring connections.

AVOIDING DAMAGE AND FALSE DISCHARGES DURING MACHINE SERVICE

E F

A G

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

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

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

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.

Controls and Operation

PROBLEMS AND CORRECTIVE ACTION 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.

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.

SEAT TOO HIGH/SEAT TOO LOW There are several things which can cause improper seat height. 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.

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.

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

COLD WEATHER STARTING

7. Turn OFF the attachment.

8. Increase engine speed to 1100 rpm and begin slow boom movements.

WARNING

• Operate the boom to raise the attachment off the ground.

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

• Operate the boom tilt function forward and back very slowly.

IMPORTANT! Cold start-ups can result in pump failure. Refer to APPROVED HYDRAULIC OILS in SECTION 3 for recommended oil viscosity and temperature ranges.

9. Place the travel speed control lever in the LOW position and operate the drive function forward and reverse a few times.

10. Observe the hydraulic oil temperature. Do not begin any work until temperature reaches 10°C (50°F).

NOTE: Cold temperatures require the use of an engine block heater and a hydraulic oil heater. Preheating of hydraulic oil is recommended as standard procedure in cold weather.

1. Follow the STARTING ENGINE instructions for this COLD WEATHER STARTING procedure, paying attention to the WAIT TO START icon on the computer display.

This message will be ON during the key RUN engine preheat time. The engine must not be started until this message automatically turns OFF. NOTE: If at any time during the warming procedure, the hydraulic filter bypass message appears on the computer display, return engine speed to LOW.

11. Increase engine speed to 1500 rpm, and begin driving to the work area in LOW travel speed. Do not go to maximum travel speed until the hydraulic oil reaches 32°C (90°F). Mulching or cutting may begin but work very slowly. The machine functions will seem to operate much slower until the systems are warmed up. Avoid operating the boom functions quickly until the hydraulic oil is above 32°C (90°F).

Work the machine for thirty minutes at 1500 rpm.

12. When the hydraulic oil reaches 32°C (90°F) and the machine has been operated for 30 minutes, it is safe to increase engine speed to HIGH.

2. During the engine warm-up period constantly monitor the engine coolant temperature and the engine oil pressure. Turn OFF the engine if any pressure or temperature does not meet the specification.

3. Continue with MACHINE PREPARATION – SYSTEM TEST AND WARM-UP in THIS SECTION. 4. Start the engine and set engine speed at LOW. 5. Confirm all of the following conditions are present before proceeding to the next step: • Engine coolant temperature reaches 60°C (140°F).

• Hydraulic oil temperature reaches −7°C (20°F).

• Cooling fan is turning.

NOTE: At a starting temperature of −18°C (0°F), it will take approximately thirty minutes to complete the above step.

6. Activate the interlock system and turn ON the attachment.

• Operate the attachment for five minutes.

Controls and Operation

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.

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

3. Crank the engine until it starts. If it fails to start after 20 seconds, stop and wait for two minutes before trying again.

IMPORTANT! To prevent damage to the starter, do not engage the starter motor for more than 15 – 20 seconds. Wait two minutes between each attempt to start the engine. If the engine fails to start, refer to the ENGINE OPERATION AND MAINTENANCE MANUAL.

• Reduced risk of post shutdown fires.

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

1. Turn the attachment OFF before leaving the work area.

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

3. Park the machine on level ground with the attachment resting firmly on the ground.

4. Reduce engine speed to LOW, deactivate the interlock system (open a cab door) and let the engine run at LOW speed for approximately three minutes (minimum) to allow dissipation of heat and also to reduce turbo speed. This will prevent loss of coolant by after boil and possible hot spot damage to the engine.

Do not increase engine speed before turning it OFF. 5. Turn OFF the engine.

6. Remove the ignition key.

NOTE: For Tier 4f machines, when the engine is stopped, all DEF solution is pumped back to tank before the engine power system is turned off. This process takes approximately 90 seconds. Refer to AFTERTREATMENT SYSTEM in SECTION 3 for more information.

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

NOTE: The attachment rotor must be stopped before exiting the cab.

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

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.

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

In the event a counter rotation is required some operators will carefully push the boom and attachment down against a suitable obstacle and lift the forward or rear sections of the track off the ground. The operator will then counter rotate the tracks while swinging the upper structure. This will disengage most of the track length from the ground during the counter rotation resulting in less site damage and potentially less track wear. This is a complex manoeuvre to only be completed with fully trained and experienced operators working in stable ground conditions.

WORK UP OR DOWN A SLOPE WHEN POSSIBLE Working across a slope can shorten undercarriage component life, so try to structure the job with minimal cross-slope activity.

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 TRANSITION AREAS

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.

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.

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.

2.117

EXTENDED MACHINE TRAVEL

OTHER FACTORS

Avoid machine travel over distances of 1 km (0.60 mi) 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.)

Application refers to the type of work you do. Shovel logging, 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.

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

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.

1. Travel with the boom and attachment tucked in as close to the machine as safety permits. This travel position distributes the load most evenly across all rollers.

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.

2. Stop the machine frequently.

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.

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

4. 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.

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.

Refer to FLUID SAMPLING PROGRAM in THIS SECTION for sample valve and drain plug locations.

TIGERCAT FLUID SAMPLING PROGRAM

HYDRAULIC OIL SAMPLES

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

A

400031

A Hydraulic Oil Sample Valve

• 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.

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.

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

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

GEARBOX SAMPLES

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

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

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

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

• 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.

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

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

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

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

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

470-044

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

• 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.

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

• Before welding on the machine be sure master switch is disconnected and disconnect multi pin connectors on engine CPU and engine wiring harness.

• Clean around fill caps before checking or adding fluids.

• Release hydraulic pressures and clean around hydraulic fittings before breaking connection. Plug or cap immediately.

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

• Clean up spills as soon as possible.

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

• Use clean hydraulic oil and filters.

• Drain dirty oil while still warm.

• Have a fire extinguisher at hand.

• Do not exceed recommended fluid levels.

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

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

• For safety when working under boom, lower to ground, support properly or install lift boom cylinder locking device. Refer to SECTION 1 for instruction on the use of the boom cylinder lock.

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

• Clean up oil spills on walking surfaces and top of engine enclosure immediately.

• 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.

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.

CAUTION

A

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.

470-108 726E-019B

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

A Charge Pressure Gauge

A portable fire extinguisher is located in operator's cab.

Check the extinguisher checked daily to ensure that it is charged. The pointer on the charge gauge should point to the green region. If the indicator falls out of this green area, service the extinguisher immediately.

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

Refer to FIRE PREVENTION in SECTION 1 for additional information.

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

Refer to the manufacturer's use and information manual for proper usage, additional information and recommended inspection and maintenance intervals.

HYDRAULIC SYSTEM NOTICE

Lubrication and Maintenance 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

WARNING: HOT HYDRAULIC OIL 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 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).

A Hydraulic Oil Hand Fill Pump B Quick-Disconnect Coupler C Suction Hose

The hydraulic oil hand fill pump, located in the hydraulic compartment behind the cab, is accessed through the service panel on the right side of the machine. It is used for adding oil to the hydraulic tank.

To add oil to the hydraulic tank: 1. Locate the suction hose (on the inside of the service door).

2. Attach the hose quick connector to the coupler on the hand fill pump.

3. Insert the end of the suction tube into the supply drum.

Before refilling, check the computer to verify which oil type is selected. Use the same type and grade of oil to refill the system. This will allow the program to optimize the cooling and warning functions to best suit the oil type. Refer to COMPUTER– ADJUSTMENT MENU – GENERAL SETTINGS in SECTION 2 for selecting hydraulic oil type setting procedure.

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

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

When refilling the hydraulic system, vent pumps, motors and valves of air by opening a plug or hose fitting located near or on top of the pumps, motors and valves until oil free of air is seen flowing out of the plug or hose fitting.

Failure to vent air from the hydraulic system could cause serious damage to hydraulic components. Tighten plugs or fittings and clean up any spilled oil when completed.

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

4. Operate the pump.

The oil is pumped directly into the hydraulic tank via a return filter. The pump should be operated at a medium speed with steady motion. Pumping too fast may cause oil to bypass the oil filter.

5. After filling is complete, disconnect the suction hose from the pump.

6. Store the suction hose on the service door.

7. Clean and spilled hydraulic oil.

HYDRAULIC OIL RETURN FILTERS B

The return oil entering the hydraulic oil tank passes through four spin-on hydraulic oil return filters mounted on two filter heads above the hydraulic oil tank. One of the filters is a water absorbing (blue) filter which is in place to assist with the removal of unwanted moisture from the hydraulic oil.

For service and replacement intervals refer to SCHEDULED MAINTENANCE in THIS SECTION.

AIR CONDITIONING SYSTEM

CONDENSER

All service work must be performed by a certified A/C technician. Charge the system with R134a refrigerant only. Polyalkylene Glycol (PAG) oil should be present in the system and must be used on O-rings and fittings.

The condenser is part of the cooler package. It changes the high-pressure refrigerant vapour to a liquid.

A/C SYSTEM TOTAL CAPACITIES R134a REFRIGERANT

1.7 kg (3.75 lb)

PAG Oil

320 ml (10.8 oz)

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

Refer to CLEANING COOLER PACKAGE in THIS SECTION for the location of the condenser.

The vapour is condensed to a liquid because of the high pressure that is driving it in, and this generates a great deal of heat. The heat is then removed from the condenser by air flowing through the condenser on the outside.

RECEIVER-DRIER B

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

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.

Tigercat 470 Mulcher 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 appropriate 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 FILTER

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.

Lubrication and Maintenance

AIR CLEANER

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.

470-001 400033

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.

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.

A Primary Element B Secondary (Safety) Element

The air cleaner on this machine uses two filter elements; a primary element and a secondary (safety) element. It is accessible through a hinged service panel on the right side of the engine compartment.

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

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.

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

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.

A Air Cleaner Unloader Valve

A mechanical filter restriction indicator is connected to the outlet side of the air filter. Replace the primary air filter when the indicator shows RED. This indicator provides a continuous reading whether the engine is running or is shut down. After replacing the filter, reset the indicator by pressing the reset button.

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.

NOTE: Replace the safety element every third primary filter change.

Remove the unloader valve (if equipped) 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.

AIR FILTER RESTRICTION SENSOR The machine is also equipped with an engine air filter restriction sensor on the outlet of the air cleaner which sends an alert message to the computer in the event of filter restriction. When the message is displayed, the air filter has reached a critical state.

Replace the unloader valve every 1000 hours.

Lubrication and Maintenance

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

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

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

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

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

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

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

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

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

The first phase of the SCR process takes place in the pipe between the DOC and Catalytic converter. High temperature exhaust gas evaporates the DEF solution instantly and, by hydrolysis, converts it into ammonia (2NH3) and carbon dioxide (CO2).Evaporation of the solution lowers exhaust gas temperature, bringing it closer to the optimum temperature required by the process.

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

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

A Catalytic Converter

The catalytic converter is located in the engine compartment between the DOC and the air cleaner.

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

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

400468

A Humidity Sensor Location

The humidity sensor is located on the air intake just past the air cleaner.

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

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

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

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

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

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.

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

CAUTION

2. Close and latch the cab door.

3. Open all engine compartment doors. Refer to ACCESS DOORS AND COVERS in THIS SECTION. 4. Turn OFF the battery disconnect switch.

5. Pressure wash:

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.

• Drive motors and compartments • Oil cooler, cooler package and enclosure screens • Engine compartment

CAUTION

• Hydraulic pumps and compartment • Main valve and compartment • Cab windows. Refer to CARE OF POLYCARBONATE WINDOWS in THIS SECTION.

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).

A

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.

Tigercat 470 Mulcher

Lubrication and Maintenance

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

Take care when cleaning, as the components can be damaged by careless handling and cleaning.

CAUTION 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.

USING THE FAN CLEAN FUNCTION TO REMOVE DEBRIS DURING OPERATION The hydraulic fan circuit has a CLEAN function for use in cleaning debris from the charge air cooler, radiator, oil cooler, A/C condenser, pump drive gearbox cooler, and air intake door screens during operation. By reversing the direction of the fan, air flows in the opposite direction, thereby forcing dust and debris off the charge air cooler, radiator, oil cooler, A/C condenser, pump drive gearbox cooler, and air intake door screens. Be sure no personnel are standing directly to the left of the machine when performing this operation. Dust and debris will fly out.

CARE OF POLYCARBONATE WINDOWS

INSPECTION AND MAINTENANCE

Most 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.

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

• Inspect all windows daily and immediately after any impacts.

Polycarbonate material is expected to resist heavy impact from large branches and falling tree tops and to absorb high levels of energy when contacted by high velocity thrown objects such as wood chips, disc saw blade teeth or broken harvester head saw chain.

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

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

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

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

• The edges of the polycarbonate window must be evenly and fully supported on a flat surface around the entire window opening at all times. Bent or dented skylight structures must be replaced immediately. Bent or dented cab structures must be evaluated immediately for possible repair or replacement.

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

• Cracks, chips, notches or scarring anywhere on the viewing surface of the window will decrease ability to resist heavy impacts. Windows with these defects must be replaced immediately.

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

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

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

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

RESISTANCE TO CHEMICALS

CLEANING INSTRUCTIONS

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

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

Other chemicals however can seriously weaken the polycarbonate.

Do not permit any of the following chemicals to come into contact with polycarbonate windows: • Acetone • Air conditioning refrigerant

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.

• Ammonia

Brand name soaps and detergents recommended for cleaning polycarbonate are:

• Anti-freeze

• Fantastik

• Benzene

• Formula 409

• Brake fluid

• Hexcel F.O. 554

• Carbon tetrachloride

• Joy

• Cutting oils

• Lysol

• Gasoline

• Mr. Clean

• Lacquer thinner

• Neleco-Placer

• Toluene

• Pine-Sol

• Turpentine

• Top Job

• 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 time-temperature related. This means higher the water temperature, the shorter the time before the polycarbonate is adversely affected.

3. Rinse the window thoroughly with lukewarm water.

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

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

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

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

3.103

Lubrication and Maintenance CAUTION

Tigercat 470 Mulcher GRAFFITI REMOVAL

• Do not use abusive cleaning procedures

• 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.

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

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

either by hand or pressure washing on polycarbonate windows.

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

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

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

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

CONCEALING HAIRLINE SCRATCHES The appearance of scratches and minor abrasions on the surfaces of polycarbonate windows can be minimized by using a mild automotive polish such as: • Johnson’s Paste Wax • Novus Plastic Polish #1 and #2 • Mirror Glaze Plastic Polish

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

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

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

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

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

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

Lubrication and Maintenance TORQUING UNDERCARRIAGE BOLTS

Tigercat 470 Mulcher 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 THIS SECTION. 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.

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.

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.

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.

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.

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.
