Introduction

S.A.E. STANDARDS ROLL-OVER PROTECTION STRUCTURES (ROPS) FALLING OBJECTS PROTECTION STRUCTURES (FOPS) 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 that the certification of approval of the ROPS, FOPS, OPS structure will become void if any such modification(s) take place.

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

Both of the above are provided that the work is carried out in the factory approved manner.

Unauthorized modifications and/or repairs made or contributed to by a customer or a Tigercat distributor may result in creating a dangerous situation and therefore the customer or Tigercat distributor will be considered to have assumed the risk involved or be negligent in creating this situation.

Tigercat will not be held responsible for situations arising from having created unauthorized modifications/ changes to the structure.

Operator's cabs are designed to ROPS, FOPS, OPS standards so that 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 roll-over protective structures.

1.3

Tigercat M718E Mulcher

Safety

GENERAL SAFETY PRECAUTIONS continued Avoid mounting or dismounting the machine in areas with slippery surfaces. If this is not possible clean up or cover slippery surfaces with a nonslip material.

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

Stopping the engine immediately after it has been working under load can result in overheating and premature wear of the engine components. Reduce engine speed to LOW IDLE and let run for approximately five minutes to allow gradual dissipation of heat and also to reduce turbo speed. This will also prevent loss of coolant by after boil and possible hot spot damage to the engine.

Machines should be completely cleaned of debris at least daily, particularly around the engine exhaust components. Hydraulic oil leaks, excess grease, fuel and oil accumulation (including spillage) should be eliminated immediately.

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

Machine should be washed completely before and after every major service.

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

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

Check windows and door guards for damage.

Working with oil

Check protective windows for cracks, a damaged window has reduced strength to stop flying objects.

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

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

Some advice which should be observed:

Do not operate the machine with any defective or inoperable components.

• •

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

•

Check all fluid levels.

•

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

• • • 1.4

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

Avoid contact with oil, particularly heated oil.

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

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

Don't put oily rags in your pockets.

Oil soiled clothing should be changed as soon as possible.

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

Tigercat M718E Mulcher

Safety When moving the machine, watch that enough clearance is available on both sides and above the machine or any of its attachments. Extra clearance may be required particularly where the ground is uneven.

GENERAL SAFETY PRECAUTIONS continued • • •

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

Avoid breathing in oil fumes.

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

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

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

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

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

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

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

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

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

If the machine must be transported, make sure that it is adequately secured to the transporting vehicle.

•

If these are found, Do Not Touch!!!

•

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

Even though the brakes are fully engaged, block the wheels to prevent movement during transport.

•

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

•

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

Install the articulation lock bar when ever the machine is to be transported.

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

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

WARNING

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

Engine exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

Maintain a charged fire extinguisher on the vehicle at all times and KNOW HOW TO USE IT. Do not carry passengers either in the cab or anywhere else on the machine. The vehicle is provided and approved with seating for the operator only.

Before moving the machine to the work site, check to ensure that all doors, panels, and access covers are installed properly and secured.

ACTUATOR

CAB EXITS There are three ways to exit the cab in case of an emergency.

1. Left door, this is also the main point of entry and is the only door that should be used under normal operating conditions to enter or leave the cab. This door is also equipped with a SAFETY INTERLOCK SWITCH. See SAFETY INTERLOCK SWITCH ON DOORS in THIS SECTION.

M726E-020

INTERLOCK SWITCH (L.H. DOOR SHOWN)

SAFETY INTERLOCK SWITCHES ON DOORS: Both doors are equipped with safety interlock switches to prevent the machine from being operated while either of the doors are open (pilot system is shut off).

2. Right door, should be used for emergency exits only. Do not use this door to routinely enter or leave the cab. This door is also equipped with a SAFETY INTERLOCK SWITCH. ALWAYS shut OFF engine before using the right door exit.

CAUTION Safety interlock switches do not lock out the steering function on machines equipped with a steering wheel.

3. Escape hatch, this is a third cab exit for use if the cab door exits become blocked.

CAUTION

This hatch is not equipped with a safety interlock switch and therefore when left open will not deactivate the pilot controls in the cab.

ALWAYS shut OFF engine before using the escape hatch exit.

Do not use the steering joystick to assist entering or leaving the cab.

Note: The engine can be started but the machine functions cannot be operated with a door open.

It is important that the operator of the machine be familiar with these emergency exits and how to use them.

To operate: Close both doors and press the pilot reset switch.

All three exits should be checked to make sure that they are operational and will function in an emergency. The safety interlock mechanism on the cab doors and escape hatch retaining mechanisms must not be tampered with or defeated.

CAUTION All functions on the machine can now be operated, either as intended or by accidentally touching them.

IMPORTANT! Unlock both doors before operating machine to allow opening from the outside in case of an emergency. Make sure that the doors are operational, open the doors twice, once using the exterior handle and once using the interior latch handle.

Once the safety interlock system has been activated, the safety of both the operator and all persons outside the cab becomes the responsibility of the operator.

The door safety interlock switches and the pilot reset switch are a safety feature and their function must not be defeated in any way.

For additional information, refer to EMERGENCY EXITS in SECTION 2 of the OPERATOR'S MANUAL.

1.9

Tigercat M718E Mulcher OPERATING SAFETY PRECAUTIONS continued MULCHING OPERATION safety 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.

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 cutter tools, cutter tool fasteners, rotor and mulching head assembly.

Ensure that all cutter tool retaining bolts are at correct torque value.

Replace all worn cutter tools.

Always replace the fastener whenever replacing a cutter tool.

Inspect the rotor for weld cracks and other damage.

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

Never start or use a machine if the rotor has missing cutting tools, missing cutting tool fasteners or a bent rotor.

Shut down the machine immediately if you feel excessive vibration when the rotating cutter is running.

Check that the cutter housing is clear and undamaged.

DANGER ROTATING CUTTER

The safety of persons outside the cab is the responsibility of the machine operator.

Danger caused by flying debris. Improper operation of the attachment and failure to follow safety precautions will result in death or serious injury.

FRONT Danger Zone

REAR Danger Zone

Safety DANGER ZONES Danger exists most prominently to the rear and front of the mulching head.

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

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

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

Poor maintenance increases the danger. Through timely inspection and replacement of worn cutter tools, fasteners and wear plates. Always heed warning signs of missing cutter tool parts or sounds of striking rocks and adjust operation to suit the site.

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

REAR danger zone Chunks of wood and rock can be thrown from the rear of the mulching head. This occurs when the mulching head is raised high enough to allow debris to escape the guard chains. 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: • • •

FRONT danger zone To the front a lower volume of projectiles may be experienced. However, no one should be allowed within the HAZARD ZONE. Refer to HAZARD ZONE in THIS SECTION. The following precautions should be followed: • •

•

726M-026

DANGER ZONES

Never allow anyone to the rear of the machine while it is in operation.

Inspect daily for damaged or missing guard chains. Replace them before operating.

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

Never allow anyone to the front of the machine while it is in operation.

Close the mulch door (if equipped) while pullworking to better contain debris. This also increases the fineness of the shredded product.

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

DO NOT operate without guards.

1.10

Tigercat M718E Mulcher OPERATING SAFETY PRECAUTIONS continued URBAN PRECAUTIONS Increased safety precautions are required when working: • • • •

Near streets Near highways In parks, on golf courses or other inhabited areas.

Near buildings

Establish Safety parameters that fit the site: • • •

String coloured warning tape to cordon off the area.

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

Erect barriers.

Assessing the potential dangers of the job site 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.

Avoid metal and wire.

Metal can break cutter tools and create a projectile hazard.

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

Use caution with Stringy Vegetation 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.

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.

Safety 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.

AVOID FENCES Do not drive the mulcher into fences, especially chain link fences. Chain link fencing can damage the rotor. Refer to AVOID METAL AND WIRE above.

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

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

IMPORTANT! To prevent component damage, always have deflector door open when preparing to fell standing trees Work within your operating skills, do not attempt to cut down a tree that is too large to handle.

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

Always 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. Pre-plan to work the area in advance before other equipment arrives.

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

Stop the rotating cutter before leaving the mulching area.

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

Inspect the rotor for clinging strands often.

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

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

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

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

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

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

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

Although fluid injection accidents are rare, the resulting injury has on occasion required the amputation of a finger, a hand or in some cases the entire limb. The longer the delay in getting professional medical aid, the further up the limb the tissue damage can spread. An injury of this type can become very serious or even fatal if not dealt with promptly and properly.

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

• Seek professional medical attention immediately.

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

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

Always wear thick protective gloves.

• Be sure to wear safety goggles for eye protection.

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

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

•

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

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

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

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

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

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

SERVICING SAFETY PRECAUTIONS continued 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.

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

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

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

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

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.

•

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

•

Remove dirt and grease from grease fittings prior to greasing.

•

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

•

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

LIGHTNING SAFETY AWARENESS

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

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

1. Designate a member of your crew to

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

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.

The electrical potential in a lightning strike can be as much as 100 million volts. Lightning strikes can occur over very large distances, even as much as 60 km (37 mi). Lightning travels both in front of and behind a thunderstorm and so strikes happen even when rain has not started or has stopped.

Lightning can hit in the same place, many times and often spreads out over 18 m (60 ft) within the soil around the strike point.

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.

•

Monitor daily weather forecasts

•

Observe local weather conditions

•

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

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

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

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

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

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

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

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

1.18

Tigercat M718E Mulcher LIGHTNING SAFETY AWARENESS continued

Safety What to do if you are outside and see lightning or hear thunder.

If you can, get inside.

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

2. If inside a building:

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

Sheds, weather shelters, hunting blinds, tents and other partially open or small structures are not safe against lightning strikes as they lack the electrically grounded components of larger buildings. They are intended for sun or rain protection only. Do not seek shelter from lightning strikes inside these structures.

•

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

•

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

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

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

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

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

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

Note that the rubber tires on motor vehicles and heavy equipment do not increase safety from lightning strikes. Lightning has already travelled a great distance through the air to strike the vehicle.

In comparison a few inches of rubber in a tire offers absolutely no additional insulation.

1.19

•

Under no circumstances whatsoever step outside of the vehicle or off the equipment to move to another shelter. Very dangerous electrical pathways to ground may go through you.

•

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

•

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

•

Do not touch any metallic objects referenced to the outside of the vehicle.

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

•

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

Tigercat M718E Mulcher LIGHTNING SAFETY AWARENESS continued

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.

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

2. Put your feet together. Crouch down like in a baseball catcher’s position. Hold your head down. Cover your ears to protect them against the noise of the thunder.

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

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

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

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

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

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

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

6. Avoid entering any small enclosures or shelters.

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

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

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

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

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

2. Call your local emergency response telephone number immediately.

3. If the victim has no pulse, their heart has stopped or they have stopped breathing, start cardiopulmonary resuscitation (CPR) or mouth –to-mouth resuscitation immediately.

Use a portable defibrillator if one is available.

4. 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.

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

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

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

11. Do not use the telephone except for emergencies.

Fire prevention

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

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

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

1. Maintain a CHARGED fire extinguisher on the machine at all times and KNOW HOW TO USE IT. 2. Remove debris and blow out dust regularly from the air intake doors, engine radiator and charge air cooler, hydraulic oil cooler, diesel fuel cooler and air conditioning condenser core to prevent overheating of the engine and hydraulics and to maintain efficient operation of the machine. Refer to CLEANING A/C CONDENSER, OIL COOLER AND RADIATOR in SECTION 2 of the THIS MANUAL. 3. Blow off all forest debris and fine organic material accumulated near hot engine exhaust components (turbocharger and exhaust manifold as well as exhaust pipes and muffler) at the completion of each work shift or more frequently when working in logging conditions where large amounts of combustible forest debris are present.

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

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

5. Inspect the machine regularly for any signs of diesel fuel or hydraulic system leakage.

Check for worn or eroded fuel or hydraulic lines before starting up any equipment.

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

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

8. Use only nonflammable solutions for cleaning the machine and components.

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

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

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

11. Park the machine at least 50 feet away from other equipment at the end of each shift.

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

1.21

Tigercat M718E Mulcher Fire prevention continued 13. Turn the battery disconnect switch to OFF at shut down to de-energize all electrical circuits.

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

Safety 17. AFTER transporting (trucking) a machine from one job site to the next, open all doors and access panels and blow off any debris that may have repositioned itself onto the engine and exhaust parts due to wind turbulence caused by the journey.

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

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

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

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

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

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

Remain with the machine until help arrives.

1.24

Tigercat M718E Mulcher 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.

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

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

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

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

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

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

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

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

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

2. In areas exposed to moisture, the dry chemical powder will combine with water to form a paste that is mildly acidic. Note that all surfaces covered by this dry chemical paste including electrical contacts are vulnerable to corrosive attack.

To neutralize the acidic paste on large surfaces, spray or wash these areas with a mixture of 3 parts hot water to 1 part baking soda. Allow this mixture to stand for several minutes before rinsing with warm water. Wash the area with a mild soap and water solution.

Rinse thoroughly with water. Blow-dry to remove all residual water.

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

Tigercat M718E Mulcher

Controls and Operation 9. GEAR SHIFT LEVER Shifting gears Gear shifting must not be done while the machine is in motion. The two speed transmission does not have the capability to mesh moving gears. If the operator shifts gears while the machine is in motion, severe damage will occur to the shift collar and its mating gears and will result in difficulty or inability to shift from one speed to the other.

In order to shift gears with minimum effort and without damaging the transmission, there must be no motion between the gear teeth of the shift collar and the teeth of the low or high speed gear.

SPEED CONTROL LEVER

8. SPEED CONTROL LEVER The speed control lever allows the operator to set the maximum speed of the machine to maintain a given speed without having to feather the drive pedals. The speed control lever is mounted on the left hand arm rest, below and to the left of the steering joystick.

229-20

Push the lever forward to increase the maximum speed.

GEAR SHIFT LEVER

Shifting Procedure: • Bring the machine to a full stop on level ground.

• Reduce the engine speed to IDLE. • Depress foot brake pedal to hold the machine stationary.

• Move the gearshift lever (push or pull) to engage the desired gear.

Pull the lever back to decrease the maximum speed of the machine. When the lever is pulled fully back the machine will be in CREEP MODE. Creep mode provides maximum available tractive force to the wheels at a reduced speed.

This lever can be used while the machine is in motion.

Note: If the gear will not engage, the shifting collar and the speed gear have not aligned.

NOTE: Machines are equipped with a creep switch. It is important to note that the speed control lever will not operate when the creep switch is in the ON position.

This can be corrected by lightly touching the steering joystick to slightly articulate the machine, which will cause the collar and gear to mesh and allow for easy shifting.

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.

Refer to height adjustment.

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

SEAT TOO HIGH/SEAT TOO LOW There are several things which can cause improper seat height. Refer to HEIGHT ADJUSTMENT and adjust seat to the desired position. If the proper height cannot be reached using one of the four height adjustment settings, it may be necessary to install the seat on a higher base.

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

AIR INTAKE PRECLEANER

5. ENGINE AIR PRECLEANER The engine air precleaner cleans engine air before it reaches the air cleaner filter elements. It removes contaminants such as dust, powder, insects, rain and snow. This precleaner is self powered and self cleaning requiring virtually no maintenance. However, it should be checked periodically to make sure that foreign materials have not plugged the intake area or the exhaust port area.

The hydraulic hand fill pump, located at the rear of the machine (mounted to the inside of the door) is used for adding oil to the hydraulic oil reservoir.

To add oil to the reservoir, lift the receiving hose out of the holder, clean the coupler on the hose and the connector on the hand fill pump and connect the receiving hose to the hand pump.

Remove the suction tube from the holder on the door and clean the tube and remove cap.

Insert end of suction tube into supply drum and operate the pump. The oil is pumped directly into the hydraulic reservoir via a return filter. The pump should always be operated at a medium speed with steady motion. Pumping too fast may cause oil to by-pass oil filter.

As the air spins, centrifugal force separates foreign materials from the clean air

Contaminants are blown out of special discharge ports by high velocity, air powered rotor

Check spinner blades for wear.

Replace if worn.

IMPORTANT! Install cap on suction tube. Reinstall the suction tube in the holder on the rear door. Disconnect receiving hose (at the coupler on the hand pump) and reinstall the hose back in the holder on the fuel tank. Wipe up any spilled oil.

The turbo II precleaner has specially designed blades that cause the incoming air to spin Turbo 2

2.41

Tigercat M718E Mulcher CARE OF POLYCARBONATE WINDOWS IN cab

Controls and Operation •

(Windshield, skylight and three rear windows) 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.

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.

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

• Inspect all windows daily and immediately after any impacts.

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

• The edges of the polycarbonate window must be evenly and fully supported on a flat surface around the entire window opening at all times.

Bent or dented skylight structures must be replaced immediately. Bent or dented cab structures must be evaluated immediately for possible repair or replacement.

• The edges of the polycarbonate window must be free from cracks, chips, notches or scarring and must not be pinched or stressed.

These defects will decrease ability to resist heavy impacts. Windows with these defects must be replaced immediately.

• • •

•

Cracks, chips, notches or scarring anywhere on the viewing surface of the window will decrease ability to resist heavy impacts.

Windows with these defects must be replaced immediately.

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

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

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

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

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

Other chemicals however can seriously weaken the polycarbonate.

DO NOT permit any of the following chemicals to come into contact with polycarbonate windows: • acetone • air conditioning refrigerant • ammonia • anti-freeze • benzene • brake fluid • carbon tetrachloride • cutting oils • gasoline • lacquer thinner • toluene •

turpentine

•

xylene

RESISTANCE TO WATER Polycarbonate material has good resistance to water up to approximately 65°C (150°F). Above this temperature the effect of water is timetemperature related. This means that the higher the water temperature, the shorter the time before the polycarbonate is adversely affected.

2.42

Tigercat M718E Mulcher

Controls and Operation

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.

•

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

•

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

CLEANING INSTRUCTIONS

•

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

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

•

DO NOT use glass cleaners in either aerosol or non-aerosol containers to clean polycarbonate windows.

The following instructions are provided to prolong the life of this protective hard coating.

•

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.

1. Rinse the window thoroughly with lukewarm water 2. Using a soft cloth, cellulose sponge or chamois, gently wash the window with a mild solution of soap or detergent in lukewarm water. Do not scrub or use brushes or squeegees.

Brand name soaps and detergents recommended for cleaning polycarbonate are: • Fantastik • Formula 409 • Hexcel F.O. 554 • Joy • Lysol • Mr. Clean • Neleco-Placer • Pine-Sol • Top Job

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

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

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

•

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

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

CAUTIONS •

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

Johnson’s Paste Wax Novus Plastic Polish #1 and #2 Mirror Glaze Plastic Polish

Refer also to RESISTANCE TO CHEMICALS 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.

Copies of all oil analysis results must be forwarded to the Tigercat Warranty Department for continued warranty coverage. If samples are taken using the Tigercat Oil Analysis Program, a copy of all results will automatically be sent to Tigercat.

Tigercat Oil 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 followup oil samples.

Refer also to OIL SAMPLE COLLECTION PROCEDURES in THIS SECTION for sample valve and drain plug locations.

TIGERCAT OIL ANALYSIS KITS Each kit includes a Pre-paid Sample Bottle and Sample Information Form. Pre-printed 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.

The same type of sample bottle can be used for all types of oil 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 oil samples.

Contact your Tigercat Dealer Parts Department to order Kits.

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

Oil sampling connector

The accuracy of the lab analysis results is very dependent on the quality of the oil sample taken. Collection of clean oil samples that are representative of the main body of oil are essential if meaningful lab results are to be obtained.

Erroneous readings may result if proper collection, handling, packaging and shipping practices are not followed prior to the sample being tested by the lab. To be able to accurately compare and trend the lab results over time, all follow-up samples should be consistently taken from the same location using the same techniques as all previous samples.

•

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

•

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

• •

BOOM, FAN, STEER, SAW RETURN FILTERS 720E-014

HYDRAULIC OIL RETURN FILTERS

Hydraulic Oil Samples: • 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.

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

•

To obtain a representative oil sample, sample valves must be purged before the actual oil sample is taken. Drain a minimum of 3 or 4 ounces of oil into a separate container and discard this oil using approved recycling methods.

•

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

Transmission, Axles and Pump Drive Gearbox Samples: • These samples can be taken during the oil change process.

Avoid contamination of the sample – replace the sample bottle cap immediately after filling the bottle to approximately ¾ full. All samples taken should be immediately forwarded to the lab for processing.

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

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

3.4

•

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

•

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

•

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

Lubrication and Maintenance

GENERAL 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. þ Clean around filler caps before checking or adding fluids. þ Release hydraulic pressures and clean around hydraulic fittings before breaking connection.

Plug or cap immediately. þ Clean up spills as soon as possible. þ Always use clean hydraulic oil and filters. þ Drain dirty oil while still warm. þ Do not exceed recommended fluid levels. þ Service all hydraulic filters after the failure of a pump, motor, cylinder or valve. Failures of this nature could contaminate the entire hydraulic system. þ Top up diesel fuel at end of each shift to reduce contamination by condensation. þ Clean up oil spills on walking surfaces and top of engine enclosure immediately. þ 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. þ 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.

þ Before welding on machine be sure master switch is disconnected and disconnect multi-pin connectors on engine CPU and engine wiring harness. þ When welding secure ground connection as close to working position as possible to prevent arcing across machined surfaces or through bearings. þ Clean away all branches, bark and chips.

Clean up all traces of oil to avoid fires. þ Always have a fire extinguisher at hand. þ For safety, always lower boom assembly to the ground when leaving cab, leaving machine unattended or during service. þ For safety, when working under boom, always lower to ground, support properly or install lift boom cylinder locking device . (Refer to section 2 in the OPERATOR'S manual) ______________________________________ CHECK EMERGENCY EXITS, MONTHLY:~ Two alternate exit routes are provided: right hand cab door and the skylight/emergency exit. These are only to be used if the left hand cab door cannot be opened.

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

GENERAL CHECK FIRE EXTINGUISHER, DAILY:~

FIRE PREVENTION Maintaining your machine properly will greatly extend its life and reduce your operating costs.

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

CAUTION AFTER transporting (trucking) a machine from one job sight to the next, open all doors and access panels and blow off any debris that could have re-positioned itself onto the engine and exhaust parts due to wind turbulence caused by the journey.

CHECK CHARGE GAUGE DAILY

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

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

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

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

Also refer to FIRE PREVENTION in SECTION 1 of THIS MANUAL for additional information.

480-110

A portable fire extinguisher is located in operator's cab. The extinguisher should be 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, the extinguisher should be serviced immediately.

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.

Air cleaner maintenance

726D-008

AIR CLEANER

ENGINE AIR CLEANER

726D-007

The air cleaner on this machine uses two filter elements; a primary element and a safety element accessible in the hydraulic pump compartment.

AIR INTAKE precleaner

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

However, it should be checked periodically to make sure that foreign materials have not plugged the intake area or the exhaust port area.

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

NOTE: Periodically remove the precleaner assembly and check the spinner assembly for wear or dirt build-up on the blades. Clean the spinner assembly or replace it if the blades are worn.

NOTE: The precleaner compartment should be checked and cleaned out daily to ensure proper operation of the precleaner.

As the air spins, centrifugal force separates foreign materials from the clean air

Contaminants are blown out of special discharge ports by high velocity, air powered rotor

726d-020

FILTER RESTRICTION INDICATOR

A filter restriction indicator is mounted to the output side of the air cleaner. This should show green when the engine is running at FULL RPM. Service is required only if the indicator shows red.

Check spinner blades for wear.

Replace if worn.

726D-008

Air cleaner unloader valve

AIR CLEANER UNLOADER VALVE

The turbo II precleaner has specially designed blades that cause the incoming air to spin Turbo 2

Only the purified air goes to the air filter

Turbo II precleaner operation

This rubber valve on the body of the air cleaner housing should be checked before every shift (8 hours). If this valve is missing, damaged or has turned hard, it will cause the air cleaner to become ineffective. The valve should suck closed at 1/3 throttle.

3.18

Tigercat M718E Mulcher

Lubrication and Maintenance

This valve should be replaced every 1000 hours.

Remove the unloader valve from the tube of the air cleaner housing. Check and clean the valve.

A good valve is soft and flexible. If plugged, be sure to check the filter elements as they may need replacing as well. Reattach the valve to the body.

Safety element

When operating in high dust conditions, the unloader valve should be checked and squeezed every two hours to release dust build-up.

In addition to the LUBRICATION AND MAINTENANCE SCHEDULE outlined in THIS SECTION, the following instructions should also be noted: The most common and damaging servicing problems are: OVER SERVICING Filter elements increase in dust cleaning efficiency as dust builds up on the media. Looks can be deceiving. A filter that looks dirty may actually be more efficient than one that is clean. A filter with dust build up on the media reaches nearly 100% dust cleaning efficiency. Only when a filter is so clogged with dirt that air restriction goes beyond engine manufacturer's guidelines, should a filter be replaced.

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

SERVICING Engine exposure to dust during servicing is a large reason for engine damage due to dust.

Abrasive dust can easily enter the intake system once the air cleaner cover and protective filter element are removed for replacement. The safety element does reduce this risk but it should also be replaced at every third primary element change.

EVERY 125 HOURS Check the Engine Air Intake System components (including the charge air cooler) rubber elbows, connector hoses, tubes and clamps for damage, hardening, wear, cracks, leaks, loose clamps or loose hanger bracket hardware and repair immediately.

Also check the Charge Air Cooler for damage, wear, cracks, or leaks and repair immediately.

Primary element 726D-006plt

air filter elements

IMPORTANT STEPS TO FOLLOW when changing filter elements 1. Release the cover latch gently to reduce the amount of dust dislodged.

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

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

NOTE: Filter elements should never be cleaned and reused. Cleaning causes dust to bypass the filter and be deposited on the inner surface of the filter media. The dust is then drawn directly into the engine.

4. Always clean the inside of the outlet tube.

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

6. Inspect the new filter for damage.

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

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

When the engine coolant temperature reaches 85°C (185°F) the sensor on the engine in conjunction with the electronic control module will send a signal to the control valve to start to turn the fan slowly. The fan speed is variable from zero up to a maximum of 2200 rpm fan speed @2200 rpm engine speed. As the temperature of the coolant increases so does the speed of the fan up to the maximum 2200 rpm fan speed @2200 rpm engine speed. At this point the engine coolant temperature will be 96°C (205°F), or higher.

When the switch is pressed momentarily to the CLEAN (PURGE) position, the control module will signal the control valve to reverse the flow of oil to the motor and turn the fan in reverse. The control module will also turn the air conditioning system OFF for as long as the fan switch is in the CLEAN (PURGE) position.

Assembly Torque

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

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

• Four bolts and washer

WASHERS BOLTS FLANGE CLAMP

Flange Port Assembly

FLANGE HEAD

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

2. Lubricate the O-ring.

3. Position flange and clamp halves.

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

5. Hand tighten bolts.

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