Introduction

THIS OPERATOR ENCLOSURE MEETS THE FOLLOWING STANDARDS: OREGON OSHA 437-007-0775:14a TIP-OVER PROTECTION STRUCTURES (TOPS) ISO 8084:1993 OPERATOR PROTECTION STRUCTURES (OPS) ISO 8083:1989 11 600J FALLING OBJECTS PROTECTION STRUCTURES (FOPS) ISO 2867:1994 SAE J1356: FEB 1988 OREGON OSHA 437-007-0775:14b,c * MODIFICATIONS AND REPAIRS:

The integrity of the TOPS, FOPS, OPS structure and its continued ability to provide the level of protection it was designed for could be seriously affected by any modifications to the structure, its mounting or to the chassis to which it is attached.

Tigercat emphasizes that the certification of approval of the TOPS, FOPS, OPS structure will become void if any such modifications take place.

Tigercat may officially grant approval for modifications only by: i)

Written approval of repairs or modifications signed by the Tigercat Engineering Manager; or

ii) Approved modifications officially released by Tigercat.

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

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

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

Operator's cabs are designed to TOPS, FOPS, OPS standards so that they will withstand force and absorb energy during a tip-over (TOPS), when resisting the impact of a falling object (FOPS) and minimize the possibility of operator injury from penetrating objects (OPS). When a permanent deflection of the structure occurs, the structure can no longer provide the original designed level of protection and should be replaced. Attempts to straighten the structure, particularly by the application of heat, can reduce still further the structures remaining capability to protect.

The mounting and the frame or chassis to which the cab is attached is considered an integral part of the TOPS, FOPS, OPS and is included in the design, test and certification of the product.

Contact the Tigercat Service department before attempting any modifications or repair to tip-over protective structures.

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

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

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

Maintain a distance of 3 m (10 ft) between the machine or boom and any power line carrying up to 50,000 volts or less plus 12 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: •

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.

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.

•

Wear disposable heavy duty gloves (neoprene) and decontaminate the affected area by washing thoroughly with limewater (Calcium Hydroxide solution).

•

Safely discard any cloths, residue and gloves after use.

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.

WARNING

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.

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.

WARNING Failure to follow all of the above instructions could result in serious injury or death from crushing.

CAUTION

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.

Do not open cab doors or window screens when cab is on a slope. The doors and screens are heavy and could swing out with considerable force. Anyone in the path of swing could be injured.

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

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

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.

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.

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.

•

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.

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.

Safety GREASE INJECTION INJURY WHEN USING PNEUMATIC GREASE GUNS

SERVICING SAFETY PRECAUTIONS Continued

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.

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.

•

• •

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

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

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

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

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.

Never use any hoses that you suspect could be defective.

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

1.16

•

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 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.

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.

1.17

Tigercat T250D Track Loader

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: • 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.

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.

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

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.

• 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 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.

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

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.

1.18

Tigercat T250D Track Loader

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.

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

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

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.

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

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

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

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.

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

2. Call your local emergency response telephone number immediately.

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

3. If the victim has no pulse, their heart has stopped or they have stopped breathing.

Start CPR or mouth-to-mouth resuscitation immediately. Use a portable defibrillator if one is available.

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.

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.

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.

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

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

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

National Lightning Safety Institute http://www.lightningsafety.com

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 COOLER PACKAGE in SECTION 2 of the OPERATOR'S MANUAL.

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.

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.

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

12. Never leave the machine parked with 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.

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

FIRE PREVENTION Continued

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.

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

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

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.

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 1.21

•

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:

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.

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

1. The fire is small and not rapidly spreading.

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

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

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

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.

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.

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

•

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.

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.

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.

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.

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.

15. THROTTLE CONTROL

This is a 3-position switch with STOP/RUN/ START positions.

This is a three position 'momentary' switch connected into the engine CPU circuit to adjust the engine rpm between the (IDLE) and (FULL) throttle set points.

STOP Position – All electrical power through the Key switch is turned OFF.

NOTE: Engage the interlock reset to increase engine speed. When the system is deactivated the engine speed will reset to minimum rpm.

Electrical power is still available for the horn, lighter, CD AM/FM radio, 2-way radio, cab dome light, defroster fan, work lights and service lights.

PRESS and HOLD this switch in the position to increase engine speed (rpm).

Release switch at desired rpm or continue to HOLD to place engine at the correct FULL throttle setting.

RUN Position – Battery is connected to all functions. Used for normal machine operation.

PRESS and HOLD this switch in the position to decrease engine speed (rpm).

Release switch at desired rpm. or continue to HOLD to place engine at the correct MINIMUM throttle setting.

START Position – Connects the battery to the start relay to start the engine. Turning the key to this position starts the engine. The key will return to RUN position when released.

17. REAR LIGHTS - OPTIONAL

NOTE: All operations should be performed at FULL throttle.

This switch controls the rear lights located on the rear of the cab. The circuit draws current directly from the battery and is protected by a fuse located in the fuse box.

Maintaining Correct Engine rpm It is most important that the IDLE and FULL rpm of the engine be correct at all times:

18. LIGHTER/24 VOLT POWER

IDLE - 800 rpm (No Load) FULL - 1850 to 1880 rpm max. (No Load) RATED WORKING — ­ 1850 rpm

Depress lighter fully into socket and wait until it pops back up. Pull lighter out of socket and use coil to light cigar(ette).

NOTE: At start-up the engine will always default to IDLE.

CAUTION: Lighter coil reaches high temperatures that can cause burns to skin and can start fire. Handle with care. DO NOT use in presence of explosive or flammable liquids or vapor. Serious injury, death and/or property damage may result.

The above values are with the hydraulic and engine oil at normal operating temperatures and no functions activated. These values are pre-set into the engine CPU (computer) and cannot be adjusted without the proper electronic programming software equipment.

19. 12-VOLT AUXILIARY POWER A 12-volt outlet with 20-amp capacity for portable devices such as phones.

Auto Idle Down If the engine is set to run at full throttle and no hydraulic functions are activated for 15 (default) seconds, the engine will idle down.

The engine will return to the set idle speed as soon as a function is activated.

20. SERVICE LIGHTS This switch controls the service light located in the engine enclosure. The circuit draws current directly from the battery and is protected by a fuse located in the fuse box.

For adjustment of the delay for the engine to idle down refer to COMPUTER, IDLE DOWN WAIT TIME in THIS SECTION.

21. WORK LIGHTS This switch controls the work lights located on the front of the cab and on the stick boom.

The circuit draws current directly from the battery and is protected by a fuse located in the fuse box.

PROBLEMS AND CORRECTIVE ACTION

Seat Too High/Seat Too Low

Rides Too Stiff/Seat Tends To Push Or Throw Operator Forward

There are several things which can cause improper seat height. Refer to the 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.

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.

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.

Controls & Operation

COLD WEATHER STARTING During cold weather, the engine idle speed is controlled by the computer to limit maximum engine speed until the hydraulic system temperature has warmed to a specific temperature based on the oil grade selected.

TEMPERATURE

21°C (70°F)

4.5°C (40°F) 1400 RPM

1850 RPM ENGINE SPEED

As the machine hydraulic system temperature rises the engine idle speed can be increased. The length of time it takes is dependent on ambient temperature and oil grade selected.

Example: ISO 46 oil grade at 21°C (70°F) or above, engine speed can be increased to maximum idle speed of 1850 rpm.

IMPORTANT! Engine should not idle longer than 4 consecutive hours. Damage to the emission control system will result. When this machine idles for an extended period excess hydrocarbon buildup is created in the SCR after treatment system. Burn off of excess hydrocarbon at full load immediately after a long idle period will generate excess heat which will cause damage to emission control system components. It will take 45 minutes at 40% load (or an SCR exhaust outlet temperature of 320°C [608°F]) to burn off the hydrocarbon that accumulates during a 4 hour long idle.

NOTE: The idle down function will not work until the engine idle speed can be increased to full rpm.

T250D-120

WARNING

DEF TANK COMPARTMENT

Use only diesel exhaust fluid (DEF) which meets ISO 22241 specifications. NEVER fill the DEF tank with any other fluid.

DEF fluid is injected into the exhaust gas stream during normal operation of the Selective Catalytic Reduction (SCR) after treatment system.

Use of other fluids may cause component damage, or a fire risk which could result in death or serious injury.

The DEF tank is located in the compartment beside the boom saddle. The DEF tank fill cap can be accessed by lifting the hinged lid in the left corner of the compartment. The DEF tank fill point is equipped with a filter to prevent contaminants from entering the tank.

DEF tank capacity is 43 L (11.4 gal US). DO NOT overfill tank. This tank is equipped with an expansion capacity of 7% required to allow for the expansion of DEF in cold temperature conditions.

DEF freezes at -11°C (12°F).

DEF is used by the SCR after-treatment system to lower the concentration of nitrogen oxides from the diesel engine exhaust of this vehicle.

A DEF level indicator is shown on the main menu of the computer display, below the fuel gauge.

It is important to avoid contamination of DEF when filling the tank as this may cause costly damage to SCR system components and affect the proper operation of the SCR system and the engine.

When DEF levels are low information messages and warnings will be shown on the computer display. Note that extremely low DEF levels may result in derating of engine performance to meet emission standard requirements. Action to correct DEF levels should be taken immediately to avoid affecting engine performance. Refer also to COMPUTER~MESSAGES AND WARNINGS in THIS SECTION.

When a problem with DEF quality is detected information messages and warnings will be shown on the computer display. Note that DEF quality problems may result in derating of engine performance to meet emission standard requirements. Action to correct DEF quality problems should be taken immediately to avoid affecting engine performance and damage to SCR after-treatment system components. Refer also to COMPUTER – MESSAGES AND WARNINGS in THIS SECTION.

The DEF tank and DEF supply lines are heated when temperatures are low, the system will thaw DEF within 30 minutes of engine start for proper operation of the SCR after treatment system.

Note also that whenever the engine is stopped all DEF is pumped back to tank before the engine power system is turned off. This process takes approximately 90 seconds. Refer to SELECTIVE CATALYTIC REDUCTION SYSTEM in SECTION 3 of THIS MANUAL.

IMPORTANT! DEF should be stored between -11°C (12°F) and 30°C (86°F) and out of direct sunlight to maximize shelf life and to avoid DEF quality problems caused by improper storage.

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. Repair or replace immediately.

If the inlet/precleaner is plugged causing a restriction to airflow, reduced engine performance and increased fuel consumption may result.

If a plugged inlet/precleaner is left too long, excessive air intake restriction may damage the rubber air intake tube. A damaged air intake tube will lead to ingestion of dirt into the engine which may result in engine failure.

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

Note that the air filter restriction indicator may not function properly if the air intake tube is damaged.

Engine failures due to improper maintenance are not covered by Tigercat or Engine Manufacturer’s Warranty and any such claim will be denied.

IMPORTANT! For peak engine performance and maximum fuel economy, please ensure that the air precleaner is regularly checked and cleaned as required. All intake air tubes and clamps should be thoroughly inspected on a regular basis and any damaged or missing components should be replaced immediately.

Controls & Operation OVER SERVICING

SAFETY ELEMENT

Filter elements increase in dust cleaning efficiency as dust builds up on the media. Looks can be deceiving. A filter that is dirty is actually more efficient than one that is clean. A filter with dust build up on the media reaches nearly 100% dust cleaning efficiency. Only when a filter is so clogged with dirt that air restriction goes beyond the engine manufacturer’s guidelines, should be replaced.

IMPROPER SERVICING

PRIMARY ELEMENT 726D-006PLT

AIR FILTER ELEMENTS

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.

IMPORTANT STEPS TO FOLLOW WHEN CHANGING FILTER ELEMENTS 6. Release the cover latches gently to reduce the amount of dust dislodged.

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

8. 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.

9. Always clean the inside of the housing.

10. Always clean the sealing surface before inserting a new filter element.

11. Inspect the new filter for damage.

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

13. Check connections hoses and tubes 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.

NOTE: Refer to diesel engine manufacturer's operation and maintenance manual for more details and additional required maintenance of the Air Cleaner or replacement of the air filter elements.

Controls & Operation CARE OF POLYCARBONATE WINDOWS IN CAB 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.

2.82

Tigercat T250D Track Loader 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.

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

Other chemicals however can seriously weaken the polycarbonate.

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

Acetone

•

Air conditioning refrigerant

•

Ammonia

•

Anti-freeze

•

Benzene

•

Brake fluid

•

Carbon tetrachloride

•

Cutting oils

•

Gasoline

•

Acquer thinner

•

Toluene

•

Turpentine

•

Xylene

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

Exposing polycarbonate to repeated steam 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.

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.

3.4

Tigercat T250D Track Loader

Lubrication and Maintenance

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

T250D-024 T250D-025

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 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.

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.

VALVE COMPARTMENT

•

To obtain a representative oil sample, sample valves must be purged before the actual oil sample is taken. Drain a minimum of 90 – 120 mL (3 or 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: • These samples can be taken during the oil change process.

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.

3.5

•

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.

Tigercat T250D Track Loader

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 Clean around filler caps before checking or adding fluids.

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.

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.

Always have a fire extinguisher at hand.

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

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

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

Clean up oil spills in engine enclosure immediately.

WARNING

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.

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

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

Clean away all branches, bark and chips.

Clean up all traces of oil to avoid fires.

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.

•

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

•

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

•

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

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.

IMPORTANT! 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 repositioned itself onto the engine and exhaust parts due to wind turbulence caused by the journey.

SLIDING WINDOW HANDLE

1. Pine needles and bark when allowed to accumulate, form a fuel source that when ignited is extremely difficult to extinguish. A thorough program of regular cleaning and washing will reduce the possibility of a fire starting. In the event a fire does start, the regular cleaning program will improve the chances of successfully extinguishing a fire.

Open the right side window by lifting the latch handle and slide the window open.

INSIDE CAB

2. Pay close attention to wiring and hoes routing 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.

234T-046 234T-047

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

R.H. WINDOW SCREEN

On machines equipped with window screens, there are two hand knobs (1), one on the inside and one on the outside that can be removed to open the window screen. Only one hand knob has to be removed to open the window screen as follows:

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

From inside the cab: Open the cab window and turn the inside hand knob (1) counterclockwise to remove the hand knob and open the window screen. Push the window screen out to open it. Exit the cab if you can safely do so.

From outside the cab: The window screen can also be opened from the outside by unscrewing the hand knob on the outside (1) and remove it. When the hand knob is removed the screen can be swung open.

It is therefore essential that this exit be inspected monthly to ensure it is operational.

AIR CLEANER UNLOADER VALVE

A filter restriction indicator is located in the engine enclosure beside the air cleaner. 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 restriction 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.

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.

NOTE: Replace the safety element every third primary filter 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. Re-attach the valve to the tube.

The valve should suck closed at about 1/3 of full throttle.

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

IMPORTANT STEPS TO FOLLOW WHEN CHANGING FILTER ELEMENTS

AIR 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.

1. Release the cover latches gently to reduce the amount of dust dislodged.

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

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

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.

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.

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 housing.

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

6. Inspect the new filter for damage.

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

8. Check connections hoses and tubes for an air tight fit. 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.

NOTE: Refer to diesel engine manufacturer's operation and maintenance manual for more details and additional required maintenance of the Air Cleaner or replacement of the air filter elements.

AIR CLEANER PRECLEANER

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. The air precleaner should be checked every 8 hours to make sure that foreign materials have not plugged the intake area or the discharge louver area. Clean as required.

IMPORTANT!

480-017

PRECLEANER OPERATION

OPERATION: 1. Air enters the precleaner.

2. Specially designed vanes move dirty air toward the impeller.

The air precleaner must be checked every 8 hours and cleaned as required.

3. The spinning impeller spins the air creating centrifugal force to separate contaminants from the clean air.

If the inlet/precleaner is plugged causing a restriction to airflow, reduced engine performance and increased fuel consumption may result.

5. Clean air enters the intake to the air cleaner.

4. Contaminants are blown out the discharge louver.

If a plugged inlet/precleaner is left too long, excessive air intake restriction may damage the rubber air intake tube. A damaged air intake tube will lead to ingestion of dirt into the engine which may result in engine failure.

Note that the air filter restriction indicator may not function properly if the air intake tube is damaged.

Engine failures due to improper maintenance are not covered by Tigercat or Engine Manufacturer’s Warranty and any such claim will be denied.

IMPORTANT! For peak engine performance and maximum fuel economy, please ensure that the air precleaner is regularly checked and cleaned as required. All intake air tubes and clamps should be thoroughly inspected on a regular basis and any damaged or missing components should be replaced immediately.

Lubrication and Maintenance The DOC/SCR after treatment system consists of the following components:

DIESEL OXIDATION CATALYST / SELECTIVE CATALYTIC REDUCTION AFTER TREATMENT SYSTEM (DENOX 2.2 SYSTEM - TIER 4 FINAL) The engine on this machine is equipped with a combination Diesel Oxidation Catalyst (DOC) and high efficiency Selective Catalytic Reduction (SCR) after treatment system to limit the nitrogen oxide exhaust gas values (NOX) to meet Tier 4 Final emission standard requirements with low fuel consumption. This process is electronically controlled by the DENOX 2.2 system.

The diesel oxdation catalyst (DOC) uses oxidation at high temperatures to convert carbon monoxide (CO), hydrocarbons (HC) and the soluble organic fraction (SOF) of diesel particulates into inert compounds, carbon dioxide (CO2) and water vapour (H2O). In addition the DOC converts nitrogen oxide (NO) into nitrogen dioxide (NO2).

Increased NO2 levels enhance the performance of the SCR catalyst at low temperatures and increase the effectiveness of the DOC/SCR aftertreatment system as a whole.

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

DOC/SCR AFTER TREATMENT SYSTEM

The DOC/SCR after treatment system is electronically managed by the DeNOX 2.2 system incorporated into the engine control unit (ECU).

The ECU calculates and adjusts the flow rate of the DEF solution into the system based on current engine speed, torque delivered, exhaust temperature, amount of nitrogen oxides and ammonia present.

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

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

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

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

IMPORTANT !

Engine should not idle longer than 9 consecutive hours. Damage to the emission control system will result. When this machine idles for an extended period excess hydrocarbon buildup is created in the DOC/SCR after treatment system. Burn off of excess hydrocarbon at full load immediately after a long idle period will generate excess heat which will cause damage to emission control system components.

The first phase of the SCR process takes place in the first part of the catalytic converter: high temperature exhaust gas evaporates the DEF solution instantly and, by hydrolysis, converts it into ammonia (2NH3) and carbon dioxide (CO2).

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

SUPPLY MODULE

SUPPLY MODULE The supply module is located on the frame under the engine. Access it from underneath the rear of the machine.

The supply module pump picks up the DEF solution from the tank and sends it under pressure to the dosing module, mounted on the mixer tube incorporated into the diesel oxidation catalyst.

DEF is injected into the exhaust at the outlet of the diesel oxidation catalyst and upstream of the catalytic converter.

DIESEL OXIDATION CATALYST (DOC) DIESEL OXYDATION CATALYST (DOC) The diesel oxdation catalyst (DOC) uses oxidation at high temperatures to convert carbon monoxide (CO), hydrocarbons (HC) and the soluble organic fraction (SOF) of diesel particulates into inert compounds, carbon dioxide (CO2) and water vapour (H2O).

In addition the DOC converts nitrogen oxide (NO) into nitrogen dioxide (NO2). Increased NO2 levels enhance the performance of the SCR catalyst at low temperatures and increase the effectiveness of the DOC/SCR aftertreatment system as a whole.

The DOC is located upstream of the catalytic converter (SCR & CUC) and at its outlet incorporates the mixer tube and the mounting for the dosing module.

Assembly Torque The four-bolt port is simply a circular opening (flow passage) surrounded by four tapped holes in a certain pattern for acceptance of the flange clamping bolts. The flat surface of the port compresses the O-ring contained in the groove in the flange head when the clamp bolts are torqued. In some instances, the groove is in the port and not in the flange head. The bolts, through the clamp halves, clamp down the flange head 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.

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

• 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.
