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

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

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

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

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

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

Some advice which should be observed: 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.

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

•

Tigercat 250B Loader

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

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

GENERAL SAFETY PRECAUTIONS Continued Safety Hazards – Viton Seals O-rings and other seals manufactured of Viton material (fluorine rubber) produce a highly corrosive acid (Hydrofluoric) when subjected to temperatures above 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 addition 1,000 volts above the 50,000 volt level.

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

If State/Provincial, local or job site regulations require even greater safety distances than stated above, 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 these are found, Do Not Touch!

•

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

•

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

•

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

If the machine must be transported, make sure that it is adequately secured to the transporting vehicle. Refer to vehicle moving instructions page in SECTION 2 of the OPERATOR'S MANUAL. Stopping the engine immediately after it has been working under load can result in overheating and premature wear of the engine components.

Reduce engine speed to LOW IDLE and let run for approximately 5 minutes to allow gradual dissipation of heat and also to reduce turbo speed. This will also prevent loss of coolant by after boil and possible hot spot damage to the engine.

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

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

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

SERVICING SAFETY PRECAUTIONS Continued

When opening or closing power operated engine door, watch for personnel in door areas.

Use the proper tool for the job. Repair or replace worn or damaged tools including lifting equipment immediately.

If the engine is running inside a building, ensure that sufficient ventilation is available to prevent a build-up of toxic exhaust fumes. Run the engine only when it is necessary for testing or adjustments.

Keep your hands, feet, head, and loose clothing away from power driven parts. Tie long hair behind your head. Remove rings and other jewelry to prevent electrical shorts and entanglement in moving parts.

Always be aware of machine pinch points that could cause injury. Never place body parts within the range of motion of the working parts of the machine.

Work in a ventilated area. If it is necessary to run an engine in an enclosed area, use an exhaust pipe extension to remove toxic exhaust fumes.

Never stand under an object supported with hydraulics. Always use safety stands or a locking device.

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

WARNING Always follow attachment manufacturer's instructions and safety warnings before approaching attachment head to make adjustments.

WARNING DO NOT work below or behind a machine that is parked on a grade.

Safety

SERVICING SAFETY PRECAUTIONS Continued

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

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.

•

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.

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.

•

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 it 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.

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.

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.

1.14

•

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.

Safety LIGHTNING SAFETY

LIGHTNING SAFETY AWARENESS

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

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

1. Designate a member of your crew to:

WHAT IS A LIGHTNING STRIKE?

• Monitor daily weather forecasts

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.

• 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.

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

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

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

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

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

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

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

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

Thunder always accompanies lightning. When lightning occurs, the air through which it travels is instantaneously heated to a temperature more than 28,000°C (50,000°F). The air expands rapidly due to this heating, then quickly contracts as it cools. It is this contracting shock wave that we hear as thunder.

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

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

LIGHTNING SAFETY AWARENESS Continued

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: If you can, get inside.

• 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:

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

• 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.

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.

• 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.

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 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 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.

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

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.

1.17

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 SAFETY AWARENESS Continued

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:

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

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

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. 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.

2. Call your local emergency response telephone number immediately.

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

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

Use a portable defibrillator if one is available.

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

6. Avoid entering any small enclosures or shelters.

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

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

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

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

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

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

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

11. Do not use the telephone except for emergencies.

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.

FIRE PREVENTION

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

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

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

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

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.

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.

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

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

1. Maintain a CHARGED fire extinguisher on the machine at all times and KNOW HOW TO USE IT.

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.

2. Remove debris and blow out dust regularly from the air intake doors, engine radiator and charge air cooler, hydraulic oil cooler, diesel fuel cooler and air conditioning condenser core to prevent overheating of the engine and hydraulics and to maintain efficient operation of the machine. Refer to CLEANING A/C CONDENSER, OIL COOLER AND RADIATOR in SECTION 2 of the OPERATOR’S MANUAL. 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.

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.

1.19

Tigercat 250B Loader

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.

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

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

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

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

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

EQUIPMENT FIRES ADVERSELY EFFECT YOUR ABILITY TO LOG, MAY INCREASE YOUR INSURANCE PREMIUMS DRAMATICALLY OR PREVENT YOU FROM OBTAINING INSURANCE COVERAGE AT ALL. WHAT TO DO TO PREPARE FOR A MACHINE FIRE

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

•

Prevent the fire from happening in the first place by ensuring that all machine systems are frequently inspected and always well maintained.

•

Ensure that any hand held fire extinguishers are charged and in working order. Fire extinguishers require routine care. Follow the manufacturer’s instructions for inspection and maintenance shown on the label of the fire extinguisher and in the extinguisher manufacturer's manual.

•

Ensure that any pressurized water systems on the machine (if applicable) are charged and in working order. Refer to PRESSURIZED WATER SYSTEM MAINTENANCE in SECTION 3 of the OPERATOR’S MANUAL.

•

Ensure that you have the proper fire extinguishers on site. Most fires involving mobile forestry equipment will be Class A or B.

Dry chemical extinguishers should be rated ABC and pressurized water extinguishers should be rated A.

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

Class A fires involve ordinary combustibles such as wood, cloth, paper, rubber and many plastics, Class B fires occur with flammable liquids such as diesel fuel, oil and grease and Class C fires apply to energized electrical equipment.

1.20

Tigercat 250B Loader

Safety WHAT TO DO WHEN A MACHINE FIRE OCCURS

FIRE PREVENTION Continued •

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

Ensure that 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.

•

Ensure that your fire detection system* is in working order. Refer to FIRE DETECTION SYSTEM in SECTION 2 of the OPERATOR’S MANUAL.

•

Ensure that your fire suppression system** is charged and in working order. Refer to FIRE SUPPRESSION SYSTEM in SECTION 2 of the OPERATOR’S MANUAL.

•

Ensure that you are familiar with the recommended procedures for fire contained in the emergency action plan of your company.

•

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

2. Shut the engine off.

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.

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

1. Workers assigned to fire fighting duties must be physically capable of performing them safely and effectively.

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

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

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

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

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

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

•

Ensure that after you have received the training as outlined above, that you know how to use the fire extinguisher, the pressurized water system (if applicable) and the fire suppression system on your machine.

There is not enough time available to read instructions during a fire emergency.

•

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

Safety WHAT TO DO AFTER A MACHINE FIRE HAS OCCURRED

FIRE PREVENTION Continued

Before returning the machine to work:

•

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

1. Ensure that the cause of the fire is determined and all appropriate repairs are completed.

•

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.

2. Ensure that the Fire Detection System or the Fire Suppression System is properly serviced and in working order (if applicable).

•

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.

3. Ensure that all extinguishers used in fighting the fire are replaced or recharged.

•

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

•

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

Safety

DRY CHEMICAL CLEANUP PROCEDURES

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

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

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

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

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

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

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.

5. VACUUM TANK SWITCH WITH LIGHT (2500501 – 2500560)

6. STABILIZER DIRECTION SELECTOR SWITCH

This is a two position ON/OFF switch. The light in the switch illuminates to indicate that the vacuum system is ON.

The 4 stabilizers are controlled using the buttons located on the instrument panel to the right of the seat.

With the key switch in the OFF position and the key removed, turn the vacuum switch to the ON position to run the compressor/ vacuum pump. This will create a vacuum condition (9 in. Hg) in the hydraulic tank. The vacuum pump will automatically start and stop as necessary to maintain the tank vacuum.

The vacuum switch will also lock-out the start solenoid to prevent the engine from being started.

• First select a direction (up or down) using the Stabilizer Direction selector switch (6).

The center position on the switch turns off all stabilizers. This switch should be left in the center position whenever stabilizers are not being moved. This will prevent accidental operation of the stabilizers.

• Next, use buttons (6A), (6B), (6C) or (6D) to control each stabilizer separately or use the ALL button (6E) to move all stabilizers at once. The ALL button should be used to ensure that each stabilizer is applying equal pressure to the ground prior to operating the loader or lifting any loads.

By creating a vacuum in the hydraulic tank, it becomes possible to perform service work on the hydraulic system without the need to drain the hydraulic tank. The vacuum inside the tank holds the oil in the tank. The air compressor used for the hydraulic reservoir pressurization acts as a vacuum pump for this purpose with the use of a small solenoidoperated diverter valve.

See SETTING THE MACHINE in this section.

7. ANTI-STALL SWITCH WITH LIGHT • This is a 2-position ON/OFF switch. The light in the switch will come on to indicate that the anti-stall system is ON.

Relieve the vacuum in the tank by placing the vacuum switch in the OFF position and opening and closing the air vent ball valve on the hydraulic tank.

• Use this switch to turn ON the electronic load control system. This will automatically prevent overloading of the engine whenever several high load functions are in use at the same time.

NOTE: Do not attempt to start the engine until the tank has been pressurized. See CHARGE TANK SWITCH in this section.

If engine stalling occurs, check:

IMPORTANT! It is recommended that the vacuum pump be operated once per week for about 30 minutes when the hydraulic system is at operating temperature. This will remove water that may have accumulated in the hydraulic tank as a result of condensation.

• Anti-stall switch is in ON position.

• Anti-stall electrical system fuse.

• Anti-stall system malfunction.

8. SWING BRAKE SWITCH WITH LIGHT (2500501 – 2500560) This is a two position ON/OFF switch. The light in the switch will come on to indicate that the swing brake is ON.

IMPORTANT! It is recommended that the start key be removed while servicing the hydraulic system.

Placing this switch in the ON position will apply the swing brake and prevent the upper structure from turning. The brake is also engaged whenever the pilot system is shut off (left armrest in raised position), but as an added safety precaution, the brake should always be applied with this switch when leaving the cab. The swing brake is a springapplied, hydraulically-released, multi-disc brake.

Do not attempt to START the machine or turn key to the RUN position. The vacuum pump only operates when the key switch is in the OFF position.

Do not leave machine unattended or overnight with vacuum pump on.

12. PILOT SYSTEM SHUT OFF LIMIT SWITCH

MAINTAINING CORRECT ENGINE RPM

When the L.H. armrest is placed in the UP position, a limit switch shuts off the pilot system deactivating all operating functions and throttles the engine speed down to LOW Idle. When the L.H. armrest is placed in the DOWN position, the limit switch closes and turns ON the pilot system. Operating functions are not reactivated until the Pilot Reset Switch (16) is pressed.

It is most important that the IDLE and FULL engine speeds be correct at all times: • IDLE – 900 rpm (no load) • FULL – 1850 to 1880 rpm max (no load) • RATED WORKING – 1800 rpm NOTE: At start-up the engine will always default to IDLE. The above values are with the hydraulic and engine oil at normal operating temperatures and no functions activated. These values are preset into the engine CPU and cannot be adjusted without the proper electronic equipment programming software.

In addition to the LUBRICATION AND MAINTENANCE SCHEDULE, the following instructions should also be noted.

INTAKE TUBING AND JOINTS 250B-023

Check all air intake system components, rubber elbows, connector hoses, tubes and clamps for damage, hardening, wear, cracks, leaks, loose clamps or loose hanger bracket hardware and repair or replace immediately.

FILTER RESTRICTION INDICATOR

AIR FILTER RESTRICTION INDICATOR A filter restriction indicator is located in the engine enclosure beside the air intake grill. The indicator is remote mounted and is connected to the outlet side of the air filter with a 1/4 in. diameter hose.

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.

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

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.

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

AIR CLEANER UNLOADER VALVE This rubber valve on the tube of the air cleaner housing should be checked at the beginning of every shift. (8 hours) If this valve is missing, damaged or has become hard, it will cause the air cleaner to become ineffective. The unloader valve should be replaced every 1000 hours.

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.

Remove the unloader valve from the tube of the air cleaner housing.

Check and clean the valve. A good valve should be soft and flexible. If it is plugged, then check the filter elements, they may need replacing. Reattach the valve to the tube.

The valve should pull closed at about 1/3 throttle.

When operating in high dust conditions this valve should be checked and squeezed every 2 hours to release dust buildup.

CARE OF MACHINE

CARE OF POLYCARBONATE WINDOWS IN CAB

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

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.

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

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.

3. Lubricate all necessary points as per the maintenance schedule provided.

4. Never apply a load to a cold engine.

5. Close and secure all doors and access panel prior to operating machine.

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

6. Clean machine including all platforms, inside engine enclosure and around radiator of all dirt and debris on a regular basis.

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.

7. Keep all steps, ladders and platforms clear of oil and other material or debris that can cause an unsafe condition.

8. Ensure grapple head or boom is resting securely before shutting down the machine or servicing.

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

INSPECTION AND MAINTENANCE

RESISTANCE TO CHEMICALS

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

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.

•

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.

•

•

•

DO NOT permit any of the following chemicals to come into contact with polycarbonate windows:

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.

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

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

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

CLEANING INSTRUCTIONS

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

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.

CAUTIONS

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

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

Brand name soaps and detergents recommended for cleaning polycarbonate are: • Fantastik

•

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

•

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

•

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

•

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

•

DO NOT use glass cleaners in either aerosol or 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.

• Formula 409 • Hexcel F.O. 554 • Joy • Lysol • Mr. Clean • Neleco-Placer

CONCEALING HAIRLINE SCRATCHES

• Pine-Sol

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

• Top Job 3. Rinse the window thoroughly with lukewarm water.

• Johnson’s Paste Wax

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

• Novus Plastic Polish #1 and #2 • Mirror Glaze Plastic Polish

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.

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.

WINDOW SCREEN HAND KNOB

173-25

SIDE WINDOW SCREEN

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

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

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

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.

All handles should be hand tight only at all times.

FIRST SAMPLE There will be no charge for the first oil samples required to be taken during the 100-Hour Inspection Service that will be scheduled and performed by your Tigercat dealer. Refer to NEW MACHINE MAINTENANCE in THIS SECTION. FOLLOW-UP SAMPLES All follow-up samples must be taken as indicated in the chart above and will be the responsibility of the machine owner.

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 properly collect, prepare and ship the oil samples.

Contact your Tigercat Dealer Parts Department to order Kits.

3.3

Tigercat 250B Loader

Lubrication and Maintenance

TIGERCAT OIL SAMPLING PROGRAM OIL SAMPLE COLLECTION PROCEDURES Fill out the SIF (Sample Information Form) 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

250B-012

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.

HYDRAULIC OIL RETURN MANIFOLD

HYDRAULIC OIL SAMPLES:

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.

•

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.

•

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

•

To obtain a representative oil sample, the sample valves must be purged before the actual oil sample is taken. Drain a minimum of 90 – 120 mL (3 – 4 oz) of oil into a separate container and discard this oil using approved recycling methods.

•

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

GEARBOX SAMPLES:

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

•

These samples can be taken during the oil change process.

•

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

•

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

•

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

Lubrication and Maintenance

GENERAL Clean around filler caps before checking or adding fluids.

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.

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

Clean up spills as soon as possible.

Always use clean oil and containers.

Drain dirty oil while still warm.

Do not exceed recommended fluid levels.

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.

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

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

Clean up oil spills in engine enclosure immediately.

Always have a fire extinguisher at hand.

Before welding on machine be sure the negative battery terminal is disconnected and the anti-stall controller and all multi-pin connectors from the engine are unplugged.

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

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

Clean away all branches, bark and chips.

Clean up all traces of oil to avoid fires.

HYDRAULIC OIL RETURN FILTERS FILTER HEAD

The majority of return oil entering the hydraulic tank passes through 4 spin-on hydraulic oil filters.

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 (the filters are rated 10 micron absolute).

Each filter head has a bypass valve with a 2 bar (25 psi) cracking pressure so that oil can bypass the filters if they become restricted. The IN side of the filter heads are connected to a return manifold.

A filter restriction indicator and an oil sampling connector are mounted onto the manifold.

HYDRAULIC PILOT FILTER

PILOT PRESSURE FILTER This single full flow filter, is mounted in the output line between the pilot pump and the pilot manifold.

For service and replacement intervals see SERVICE AND LUBRICATION CHART in THIS SECTION.

SWING PUMP CHARGE PRESSURE FILTER The swing pump charge pressure filter is a full flow filter mounted on a filter head with built-in bypass.

The filter is located in the output side of the charge pump. For service and replacement intervals see SERVICE AND LUBRICATION CHART in THIS SECTION.

CASE DRAIN STRAINER The case drain strainer is used to filter all case drain oil from the pumps and motors before it returns to the reservoir. For service and replacement intervals see SERVICE AND LUBRICATION CHART in THIS SECTION. The strainer element requires no regular maintenance over the life of the machine. This element requires maintenance only in the case of damage or contamination due to a hydraulic pump or motor failure.

IMPORTANT! The strainer element is NOT a filter element.

Always use the correct replacement element. Use of an incorrect (filter type) element will result in pump damage.

IMPORTANT Contaminated hydraulic fluid can lead to premature failure of hydraulic components and costly repairs. Filters must be replaced at the recommended time intervals, Refer to SCHEDULED MAINTENANCE in THIS SECTION. Use of hydraulic oil filters other than the Tigercat brand could lead to severe wear and rapid failure of hydraulic system components.

CASE DRAIN STRAINER

Changing the filter or strainer: 1. Ensure Loader is on level ground with stabilizers down. Lower grapple to ground and stop engine.

2. Wipe clean the area around the filter and head.

3. Place rags below to catch the spillage of oil.

4. Unscrew the old filter. (Always wear face protection in case of an oil squirt.) Dispose of old filter and any oil properly.

5. Check the seating area for the gasket on the filter head and wipe it clean.

6. The new filter has an attached gasket, apply hydraulic oil to the gasket surface.

7. Screw on the new filter until the gasket makes contact with the seat in the filter head.

8. Turn filter an additional 1/2 turn by hand to tighten.

DO NOT use bottom nut for filter installation or damage/leakage may result. Bottom nut is to assist in filter removal only.

9. Start the engine and check for leaks.

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

Lubrication and Maintenance

In addition to the LUBRICATION AND MAINTENANCE SCHEDULE, the following instructions should also be noted.

AIR CLEANER MAINTENANCE The most common and most damaging air intake servicing problems are: OVER SERVICING

AIR CLEANER UNLOADER VALVE

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. When a filter is so clogged with dirt that air restriction goes beyond the engine manufacturer’s guidelines, it must replaced.

250B-023

AIR CLEANER

AIR CLEANER The air cleaner on this machine uses 2 filter elements, a primary element and a safety element.

IMPROPER SERVICING The largest single factor contributing to engine damage due to dust, is exposure during servicing.

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.

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

SAFETY ELEMENT

IMPORTANT STEPS TO FOLLOW 1. Release the seal 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. Always clean the sealing surface of the outlet tube before inserting a new filter element.

4. Always clean the inside of the outlet tube.

5. Check the old filter, it can help you detect foreign material on the sealing surface that may be causing leakage.

PRIMARY 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 center.

8. Check connection and ducts for air tight fit.

Ensure that all clamps, bolts and connections are tight. Leaks here send dust directly to the engine.

FILTER RESTRICTION INDICATOR

FILTER RESTRICTION INDICATOR A filter restriction indicator is located in the engine enclosure to the left of the frame access panel.

The indicator is remote mounted and is connected to the outlet side of the air filter with a 1/4" diameter hose. 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.

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

250B-023

AIR CLEANER

AIR CLEANER UNLOADER VALVE This rubber valve on the tube of the air cleaner housing should be checked at the beginning of every shift (8 hours). If this valve is missing, damaged or has become hard, it will cause the air cleaner to become ineffective. The unloader 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 should be soft and flexible. If it is plugged, then check the filter elements, they may need replacing. Re-attach the valve to the tube.

The valve should pull closed at engine warm-up speed.

When operating in high dust conditions this valve should be checked and squeezed every 2 hours to release dust buildup.

250B-028

AIR CLEANER

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

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