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

Tigercat T250D Track Loader

Introduction

STANDARDS FOR MACHINE OPERATOR PROTECTIVE STRUCTURES THIS OPERATOR ENCLOSURE MEETS THE FOLLOWING STANDARDS: • ISO 8082-2:2011 – ROLL OVER PROTECTIVE STRUCTURES (ROPS) • ISO 8083:2006 – FALLING OBJECTS PROTECTIVE STRUCTURES (FOPS), DROP ENERGY LEVEL 11,600J • ISO 8084:2003 – OPERATOR PROTECTIVE STRUCTURES (OPS) • SAE J2267:2007-OPERATOR FRONT PROTECTIVE STRUCTURE (OFPS) • OREGON OSHA 437-007-0775:14a, b, c– PROTECTIVE STRUCTURES FOR OPERATORS

MODIFICATIONS AND REPAIRS The integrity of the 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 structure will become void if any such modifications take place.

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

Approval will be granted, provided the work is carried out in the factory approved manner.

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

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

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

The mounting and the frame or chassis to which the cab is attached is considered an integral part of the ROPS, FOPS, OFPS, 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 HAZARDS – VITON SEALS

• 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.

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

• 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.

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

• 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.

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

• Stopping the engine immediately after it has been working under load can result in overheating and premature wear of the engine components.

Reduce engine speed to LOW IDLE and let run for approximately five minutes to allow gradual dissipation of heat and also to reduce turbo speed.

This will also prevent loss of coolant by after boil and possible hot spot damage to the engine.

• 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 neoprene gloves and decontaminate the affected area by washing thoroughly with limewater (Calcium Hydroxide solution).

• 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.

• Safely discard any cloths, residue and gloves after use.

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

• Comply with the instructions in this manual and also the regulations for the operation of this machine as outlined by your company.

SAFETY HAZARDS – OPERATING • Maintain a charged fire extinguisher on the vehicle at all times and KNOW HOW TO USE IT.

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

• Do not carry passengers either in the cab or anywhere else on the machine. The vehicle is provided and approved with seating for the operator only.

• Do not allow anyone to operate the machine who may not be physically fit or who may be under the influence of alcohol or drugs.

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

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

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

Safety

Tigercat T250D Track Loader

FLUID INJECTION INJURY WARNING

• Dispose of fluids properly. Do not pour fluids into the ground, stream, pond or lake. Before draining any fluids, know the proper way to dispose of them.

• Read, understand and follow all operating safety precautions specified by the attachment manufacturer.

WARNING Always follow the instructions and safety warnings provided by the attachment manufacturer before approaching the attachment head to make adjustments.

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

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

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

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

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.

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.

1.16

Tigercat T250D Track Loader

Safety

IN THE EVENT OF ANY SUSPECTED FLUID INJECTION INJURY:

GREASE INJECTION INJURY WHEN USING PNEUMATIC GREASE GUNS

• REPORT THE INJURY TO YOUR SUPERVISOR IMMEDIATELY.

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.

• SEEK PROFESSIONAL MEDICAL ATTENTION IMMEDIATELY.

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

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

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

When searching for possible fluid leaks:

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 search for leaks with your bare hands.

Always wear thick protective gloves.

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.

• Be sure to wear safety goggles for eye protection.

• 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.

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

• 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.

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

• Remove dirt and grease from grease fittings prior to greasing.

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

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

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

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

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

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

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

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

LIGHTNING SAFETY AWARENESS

LIGHTNING SAFETY

WHAT IS A LIGHTNING STRIKE?

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

Lightning is a discharge of the electricity produced by a thunderstorm. As the thunderstorm develops, many small particles of ice within the storm clouds bump together. These collisions create a positive charge at the top of a cloud and a negative charge at the bottom.

As this continues a second positive charge builds up on the ground beneath the cloud, concentrated around high objects such as hills, trees, buildings, equipment and even people.

Loggers can increase their chances of avoiding a lightning strike by following a few simple safety practices: • Designate a member of your crew to: • Monitor daily weather forecasts • Observe local weather conditions

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

• Alert all other members of the crew when a possible lightning threat develops • Don’t start or continue any work that cannot be stopped immediately, when a storm moves nearby.

The electrical potential in a lightning strike can be as much as 100 million volts. Lightning strikes can occur over very large distances, even as much as 60 km (37 miles). Lightning travels both in front of and behind a thunderstorm and so strikes happen even when rain has not started or has stopped. Lightning can hit in the same place, many times and often spreads out over 18 m (60 feet) within the soil around the strike point.

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

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

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

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

• Obey the rule – If you see lightning, Flee. If you hear thunder, Clear. Do not follow the now obsolete guideline to take shelter when the time between seeing lightning and hearing thunder is 30 seconds or less. This does not provide sufficient time to ensure safety.

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

The safest location during lightning activity is inside a fully enclosed, substantially constructed building, a house, office, school, shopping area, etc. These are the safest because of the electrical wiring and plumbing 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.

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.

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.

1.18

Tigercat T250D Track Loader Do not seek safety from lightning strikes in vehicles with fiberglass or plastic body shells or in convertible top vehicles. None of these are safe, as they do not offer skin effect lightning protection.

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

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

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

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

Safety WHAT TO DO IF YOU ARE OUTSIDE AND SEE LIGHTNING OR HEAR THUNDER IF YOU CAN, GET INSIDE: Run to the nearest building, motor vehicle or fully enclosed ROPS equipment cab immediately. Being anywhere outside is not safe.

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.

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

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

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

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

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

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

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

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

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

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

• Avoid entering any small enclosures or shelters.

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

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

1.19

Safety

Tigercat T250D Track Loader

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

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

• Do not use the telephone except for emergencies.

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

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

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

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

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

There is no danger to anyone helping this person.

You can touch him or her immediately.

• Call your local emergency response telephone number immediately.

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

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

Safety

FIRE PREVENTION

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

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

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

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

The following guidelines will help to keep your equipment up and running efficiently and keep the risk of fire to a minimum: • Maintain a CHARGED fire extinguisher on the machine at all times and KNOW HOW TO USE IT. • Remove debris and blow out dust regularly from the air intake doors, engine radiator and charge air cooler, hydraulic oil cooler, diesel fuel cooler and air conditioning condenser core to prevent overheating of the engine and hydraulics and to maintain efficient operation of the machine. Refer to CLEANING COOLER PACKAGE in SECTION 2.

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

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

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

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

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

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

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

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

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

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

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

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

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

1.21

Safety

Tigercat T250D Track Loader

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

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

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

• 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.

• 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. 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.

• 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.

• Make sure 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.

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

• Ensure that your fire detection system* is in working order. Refer to FIRE DETECTION SYSTEM in SECTION 2.

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

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

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

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

NOTICE

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

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

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

1.22

Tigercat T250D Track Loader

Safety

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

5. Be aware that, hoses containing engine coolant, diesel fuel or hydraulic hoses could fail during a fire.

If this happens, hot coolant, fuel or oil could possibly be ignited by the fire.

• 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.

• 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.

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

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

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

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

WHAT TO DO WHEN A MACHINE FIRE OCCURS If operating the machine when a fire occurs:

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

1. Lower all working attachments to the ground.

2. Turn OFF the engine.

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

3. Activate the fire suppression system**.

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

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

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

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

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

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

800051

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

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.

Typical Fire Extinguisher Access Hole

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

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

1.23

Safety

Tigercat T250D Track Loader

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

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.

• Make sure the machine and all components have cooled down sufficiently after a fire so that re-ignition does not occur.

• Remain with the machine until help arrives.

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

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

NOTE: 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 noncorrosive and non-conductive such as CRC Contact Cleaner 2000.

• Make sure the fire detection system* or the fire suppression system** is properly serviced and in working order (if applicable).

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

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

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

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

The following are recommendations for the cleanup and neutralizing of areas exposed to dry chemical powder: NOTE: Workers performing this work 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.

• 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 1.24

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

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

PROBLEMS AND CORRECTIVE ACTIONS RIDE IS TOO STIFF/SEAT TENDS TO PUSH OR THROW OPERATOR FORWARD The air ride control valve has over pressurized the seat air suspension. This typically happens because the operator is trying to use the air suspension to adjust the ride height rather than using the height adjustment lever to raise the seat. Refer to HEIGHT ADJUSTMENT.

200182

A Heater/Ventilation Switch B Low-Medium-High Switch

The seat is equipped with electric heating and venting modes. Two switches located at the front of the seat control these operations.

The heater/ventilation switch is a three-position switch.

The up position 'H' turns ON the seat heater and the down position 'V' turns ON the seat vent. The middle position turns OFF seat climate control.

The low-medium-high switch is a three-position switch that adjusts the heat level or ventilation fan speed depending on the mode selected on the heater/ ventilation switch.

The air ride control valve has under pressurized the seat air suspension ride adjustment. Insufficient pressure exaggerates the knee-action movement of the seat.

This usually happens because the operator is trying to lower the seat by decreasing the amount of air pressure instead of using the height adjustment lever. Refer to HEIGHT ADJUSTMENT.

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

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

The system is made up of the following components: • MD3 Computer and Display Module • Hydraulic Joysticks.(Electric Buttons) • XC21-A2 Cab Expansion Module • XA2-A0 Expansion Module • XA2-A1 Expansion Module • Engine Electronic Control Unit (ECU) • Hydraulic Control Valve Electronic Solenoids • Various controls, switches, sensors and valves not shown.

The MD3 Computer is the main controller in the system.

The MD3 Computer program is the operating system for

F G H I

XA2-A1 Expansion Module XA2-A0 Expansion Module Electro-Hydraulic Control Valves Pilot Control Valves

the computer display as well as the control system for the machine operating parameters.

As an example, the activation of the joystick buttons is transmitted to the XC21-A2 expansion module which sends the signal to the MD3 Computer electronically.

This message is then transmitted to the XA2-A0 and XA2-A1 expansion modules from the MD3 Computer and on to the hydraulic control valve solenoid controls.

The applicable hydraulic control valves will be activated allowing hydraulic oil to flow to the grapple, heel, delimber or saw functions activated by the joystick buttons.

The engine electronic control module provides electronic information to the MD3 Computer via the J1939 CAN BUS link. This information is displayed on the computer display.

OPERATING TIPS WITH LOAD SENSING

14. Set the swing brake to the ON position.

15. Set engine speed to LOW IDLE. 16. Exit cab and visually inspect machine for leaks or other machine damage. Ensure that machine is in proper working order and is in safe condition before continuing operation.

When using the controls on a load sensing system, be aware of what the load sensing system is trying to do for you. If you move the lever or pedal 20% of its total angle, the system will provide whatever pressure it takes (up to its maximum capacity if needed) to meet this speed requirement. If you move the lever past the point needed in an attempt to speed up the boom movement, you will only overshoot the speed you wanted. Relax and try to use the least amount of lever action you can.

WARNING DO NOT USE ETHER! The engine is equipped with an electrical starting aid. Use of ether may cause an explosion and severe injury.

17. Leave the cab and visually check hose connections and cylinders for leaks. Check under the machine for oil leaks.

WARNING

Load sensing systems respond to rough operation by amplifying these movements. If you find the boom is jerky or always giving feedback, you’re probably too active on the controls. If slowing down doesn’t eliminate the roughness, the margin pressure setting may be too high and can be reduced to calm down the machine’s response.

Refer to SET MARGIN PRESSURE in SECTION 4 of the SERVICE MANUAL. Refer to SET FLOW (FUNCTION SPEED) RATE in the appropriate BOOM, SWING or TRACK DRIVE sections of the SERVICE MANUAL.

DO NOT use your bare hand to check for fluid leaks.

Fluid leaks under pressure may not be visible.

When searching for leaks, wear work gloves and use a wrench or piece of wood to move hydraulic hoses. Do not grab hold of hydraulic hoses. Wear safety goggles for eye protection.

2.79

Controls and Operation

TRACK OPERATION AND WEAR PREVENTION PROTECTING STEEL TRACKS Steel tracks are designed to perform in tough underfoot conditions. Take these steps to maximize service life and reduce operating costs.

START EVERY SHIFT WITH A CLEAN UNDERCARRIAGE When mud and debris build up on the lower part of your machine, components wear at a faster rate. Do not begin work until the undercarriage area is clean.

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

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

DON'T SPIN THE TRACKS Track spinning, reduces production, it increases fuel consumption, without a corresponding increase in productivity. And it accelerates undercarriage wear, so your costs escalate. Grouser bars are especially prone to wear problems associated with track slippage.

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

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

ALTERNATE TURNING DIRECTIONS If you're always turning in the same direction, the undercarriage components on one side of the machine will wear at a different rate than those on the other side.

To ensure even wear, pay attention to the way you're turning-and change directions when possible.

Tigercat T250D Track Loader MAKE GRADUAL TURNS INSTEAD OF COUNTER-ROTATIONS Counter-rotating accelerates wear on the tracks and other undercarriage components. Don't use that technique unless job conditions demand it. Instead, turn the machine gradually while slowly moving forward or reverse. Gradual turns minimize cuts, tears and excessive wear in the undercarriage. They also reduce damage to soft or sensitive work surfaces.

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

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

WATCH TRANSITION AREAS Try to minimize travel over transition obstacles as this accelerates undercarriage wear. If you must go across a transition, position the machine 90° to the transition.

Without ground support, the undercarriage is subjected to side stresses that can result in rapid, excessive wear.

OTHER FACTORS Application refers to the type of work you do. Shovel logging, loading, grading, digging and trenching are a few examples. This factor is largely beyond your control, but generally speaking, the more you work in high horsepower, high-torque applications, the faster your undercarriage will wear.

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

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

2.80

Tigercat T250D Track Loader

Controls and Operation

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

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

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

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

TIGERCAT FLUID ANALYSIS PROGRAM

TIGERCAT FLUID ANALYSIS KITS

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

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

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

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

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

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

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

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

Contact your Tigercat Dealer Parts Department to order Kits.Seditas natibus, acia nosam, et veles ea voluptas solupta sit rent apiendae nim vitam vitistia

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

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

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

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

TIGERCAT FLUID SAMPLING PROGRAM

A

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

HYDRAULIC OIL SAMPLES

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

Collection of clean fluid samples that are representative of the main body of fluid are essential if meaningful lab results are to be obtained.

• Take hydraulic oil samples from the circulating oil flow at operating temperature, with no functions actuated, using sample valves that are permanently located on the machine.

• 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.

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, consistently take all follow-up samples from the same location using the same techniques as all previous samples.

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

GEARBOX SAMPLES

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

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

• 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.

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

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

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

• Avoid contamination of the sample – replace the sample bottle cap immediately after filling the bottle to approximately ¾ full. Immediately forward all samples taken to the lab for processing.

• 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.

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

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

GENERAL

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

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

• Always have a fire extinguisher at hand.

• Clean around filler caps before checking or adding fluids.

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

• 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.

• 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.

• Before welding on machine, be sure to disconnect all electrical connections and follow all servicing safety precautions as outlined in the WELDING, PRIOR TO of SECTION 1.

• 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.

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

DO NOT OPERATE the machine until the exhaust leak is repaired.

FIRE PREVENTION

SCHEDULED MAINTENANCE

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

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

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

FREQUENTLY

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

• Check for water in fuel filter/water separator.

• Visual engine check.

• Check the engine cooling air intake screens for possible restriction.

• Check for debris, snow and ice buildup on emergency exits and remove accumulation immediately.

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

In the event a fire does start, the regular cleaning program will improve the chances of successfully extinguishing a fire.

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

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

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

Refer to FIRE PREVENTION in SECTION 1 for additional information.

HYDRAULIC SYSTEM NOTICE

Tigercat T250D Track Loader IMPORTANT! Before servicing the hydraulic system, park the machine on level ground. Refer to PARKING THE MACHINE in SECTION 1.

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

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

Use of filters other than genuine Tigercat replacement filters is not recommended. Replace filters at the recommended time intervals. Refer to scheduled maintenance in this section.

WARNING

WARNING: HOT HYDRAULIC OIL AND HOT MACHINE SURFACES CAN CAUSE SERIOUS BURNS! • Before servicing the machine, allow the engine cooling system, fuel system, exhaust system, hydraulic system and machine surfaces to cool down.

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

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

Hydraulic Tank Vacuum System

Air Vent Check Valve Vacuum Sensing Switch Vacuum Pump Solenoid Valve Air Vent Breather Hydraulic Tank

The purpose of the vacuum pump system is to hold the hydraulic oil in the tank when servicing pumps and other hydraulic components, minimizing any oil spill. When activated, a solenoid valve closes off the hydraulic tank breather air supply. The pump removes tank air to create a vacuum, which then holds the oil in the tank. This system eliminates the need to drain the hydraulic tank beforehand.

NOTE: When the ignition key is in the RUN position, the vacuum pump system will not start. Alternatively if the vacuum pump is on, the engine cannot be started. The vacuum pump also will not start if the battery disconnect switch is in the OFF position.

Do not use the vacuum pump when changing hydraulic filters, instead use the Air Vent Valve to release pressure from the hydraulic tank. Using the vacuum pump system while changing filters creates the risk of introducing much more air into the hydraulic system.

The vacuum system can be used when changing the case drain strainer. Refer to FILLING TANK WITH VACUUM in THIS SECTION.

Activating the pump 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.

Relieve the vacuum in the tank by placing the vacuum switch in the OFF position.

NOTE: The engine will not start until the tank vacuum has been relieved.

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

Lubrication and Maintenance

Tigercat T250D Track Loader

REFILLING THE HYDRAULIC SYSTEM When filters are replaced, there is a nominal amount of oil loss through leakage and oil contained in the filters.

This requires a hydraulic system top-up or refill.

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

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

Refer to ADD OIL TO THE HYDRAULIC OIL TANK in THIS SECTION. NOTE: Changing strainers, filters and replacing the hydraulic oil tends to aerate the oil. For maximum pump life, the machine should sit for one hour after servicing to allow entrained air to escape from the oil prior to applying working pressures to the pumps.

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

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

Check all hydraulic system components for proper operation after hydraulic oil has been replaced.

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 filter (color blue) 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 1.7 bar (25 psi) cracking pressure so that oil can bypass the filters if they become restricted. Before this valve is activated, a 1.4 bar (20 psi) filter restriction pressure switch installed in the return manifold, will send a signal to the computer control system when an oil flow in excess of 1.4 bar (20 psi) is encountered at the return filters. This pressure switch closes and the hydraulic oil filter bypass icon displays RED on the MD3 Computer and the alarm will sound.

The compressor draws in the low-pressure refrigerant vapour from the A/C system.

EXPANSION VALVE

The compressor is powered by a separate drive belt connected to the engine camshaft. When the A/C system is turned on, the compressor pumps refrigerant vapour under high pressure to the condenser.

The high pressure liquid refrigerant flows into the expansion valve and then passes through a variable orifice. The orifice limits the speed and therefore the flow of refrigerant causing the pressure of the refrigerant to drop. The refrigerant exits the expansion valve as a low pressure liquid.

A Engine Air Precleaner – Top of Engine Compartment

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

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

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

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

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

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

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

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

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

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

In addition to the SERVICE AND LUBRICATION SCHEDULE outlined in THIS SECTION, the following instructions should also be noted.

NOTE: Replace secondary (safety) filter every third primary filter change.

3.54

Tigercat T250D Track Loader

Lubrication and Maintenance AIR INTAKE FILTER RESTRICTION INDICATOR

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

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

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

A

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.

T250D-147

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

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

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

NOTE: DO NOT clean and reuse filter elements.

Cleaning causes dust to bypass the filter and be deposited on the inner surface of the filter media.

The dust is then drawn directly into the engine.

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. All clamps, bolts and connections must be tight.

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

A Air Intake Filter Restriction Indicator

The machine is also equipped with an engine air filter restriction sensor which sends a signal to the computer in the event of filter restriction. The engine air intake pressure icon turns YELLOW when service to the filter is required and turns RED, along with an ALERT message, when service to the air filter has reached a crtitical state.

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, 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 idle.

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

Lubrication and Maintenance

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

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

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

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

IMPORTANT! DO NOT idle the engine longer than one hour.

Damage to the emission control system will result.

When this machine idles for an extended period, excess hydrocarbon buildup is created in the DOC/ SCR aftertreatment system. Burn off of excess hydrocarbon, at full load, immediately after a long idle period, generates excess heat which causes damage to emission control system components.

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

The DOC/SCR aftertreatment system is electronically managed by the DENOX 2.2 system incorporated into the engine 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 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.

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 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 supply module pump picks up the DEF solution from the tank and sends it under pressure through the dosing module filter 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.

A Catalytic Converter

The catalytic converter is located on the left side of the engine compartment. Chemical reactions inside the catalytic converter reduce nitrogen oxides (NOx) in the exhaust gas.

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

The first phase of the SCR process takes part 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.

T250D-119

A DOC B Mixer Tube

The mixer tube is incorporated into the outlet of the DOC upstream from the catalytic converter.

The insulated high-turbulence mixer tube is used to mix the DEF solution and exhaust gases together before they enter the catalytic converter.

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).

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.

CLEANING COOLER PACKAGE

Tigercat T250D Track Loader PROCEDURE

The A/C condenser core is located on the right side of the machine and is one of the cores in a stack of four that make up the cooler package. The cooling fan is mounted on the front of the engine. The fan draws air from the right side of the machine through the door screen and the cooler package blowing it out of the opposite side of the machine.

Remove the three capscrews and washers and swing open the screen door on the right side of the engine compartment.

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

• Always use personal protective equipment to guard against flying debris.

Charge Air Cooler Radiator A/C Condenser Oil Cooler

The cooler package should be manually checked every eight hours (every shift) or more often where conditions cause accumulation of twigs, leaves, pine needles and dust. All of the engine enclosure doors should also be checked.

This cooler package must be checked daily and may require thorough cleaning on a regular basis depending on operating conditions. Compressed air or water may be used for cleaning. Use personal protective equipment to guard against flying debris.

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

Care must be taken when cleaning this unit, as the components can be damaged by careless handling and cleaning.

CARE OF POLYCARBONATE WINDOWS

INSPECTION AND MAINTENANCE

Most windows used in the cab are made from a polycarbonate resin thermoplastic. This material is a replacement for glass when improved strength, durability and safety is required.

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

• Inspect all windows daily and immediately after any impacts.

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

• 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 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.

• 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.

Refer to WINDOWS– CARE OF POLYCARBONATE WINDOWS– INSPECTION AND MAINTENANCE in THIS SECTION for detailed information regarding inspection and maintenance of polycarbonate windows.

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

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

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

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

RESISTANCE TO CHEMICALS

CLEANING INSTRUCTIONS

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

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

Other chemicals however can seriously weaken the polycarbonate.

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

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

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

• Ammonia

Brand name soaps and detergents recommended for cleaning polycarbonate are:

• Anti-freeze

• Fantastik

• Benzene

• Formula 409

• Brake fluid

• Hexcel F.O. 554

• Carbon tetrachloride

• Joy

• Cutting oils

• Lysol

• Gasoline

• Mr. Clean

• Lacquer thinner

• Neleco-Placer

• Toluene

• Pine-Sol

• Turpentine

• Top Job

• Xylene

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

3. Rinse the window thoroughly with lukewarm water.

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

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

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

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

3.86

Tigercat T250D Track Loader CAUTION

Lubrication and Maintenance 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.

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

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

• 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.

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

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

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

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