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

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

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

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

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

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

Safety

WORKING WITH OIL

SAFETY HAZARDS – VITON SEALS

Direct contact with oil implies a risk of skin complaints (example: eczema). Observe strict hygiene.

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

Observe the following when working with oil: • Oils used in this machine may be hot enough to cause serious burns.

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

• Avoid contact with oil, particularly heated oil.

• Wash off oil on the skin immediately with soap and water.

• Wear protective gloves. Clean hands before putting on gloves. Apply protective cream to the hands to make washing easier.

• Don't put oily rags in your pockets.

• Change oil soiled clothing as soon as possible.

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

• Attend to cuts and abrasions immediately. Clean them and apply first-aid.

• Avoid breathing in oil fumes.

The following procedures are recommended when inspecting equipment subjected to high temperatures such as fire: • Visually inspect any seals or gaskets which have suffered from heat damage. They will appear black and sticky. If these are found, DO NOT TOUCH! • Determine the material composition of any seals or gaskets, If fluoroelastomer seals (Viton, Fluorel, or Tecmoflon) have been used, the affected area must be decontaminated before undertaking further work. Natural rubber and nitrile materials are not hazardous.

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

• Wash hands and arms frequently, for example, at each meal break or as often as possible.

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

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

Safety

Tigercat 250D Loader

SAFETY HAZARDS – OPERATING • Maintain a charged fire extinguisher on the vehicle at all times and know how to use it.

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

• Be aware, when performing service and maintenance tasks, 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.

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

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

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

• Read, understand and follow all general safety precautions specified in the ATTACHMENT MANUFACTURER'S DOCUMENTATION.

• 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.

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

• Maintain a distance of 3 m (10 ft) between the machine including the boom or attachment, and any power line carrying up to 50,000 V. Add 1.5 m (5 ft) for each 150,000 V increment beyond 50,000 V. For example, if a power line carries 350,000 V, keep back at least 6 m (20 ft).

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

WARNING Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

Wash hands after handling.

• If the machine must be transported, it must be adequately secured to the transporting vehicle.

• 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 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.

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

Hydraulic and diesel fuel systems on forestry machines operate at very high pressures, often 207 bar (3000 psi) and above. If a loose connection or a defect in a hose occurs, 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. The best defence against suffering the effects of fluid injection is to prevent the accident from occurring in the first place.

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

• Wear safety goggles for eye protection.

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

Initially, an accidental fluid injection beneath the skin may only produce a slight stinging sensation. There is a danger that you will tend to ignore this, thinking that it will get better with time. Most often, it does not! Within a very short time the wound may begin to throb painfully, indicating that tissue damage has already begun.

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

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.

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

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

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

WHEN PERFORMING ANY SERVICE WORK • Stop the engine and relieve all diesel fuel or hydraulic pressure before disconnecting any lines or otherwise working on the system.

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

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

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

Safety

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

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

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

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

Prior to using a high pressure pneumatic grease gun, perform the following: • All operators of high pressure pneumatic grease guns MUST be trained in the hazards of its operations and the treatment for such injuries.

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

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

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

• Install protective shrouds on all grease gun nozzles as safety devices.

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

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

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

Safety

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

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

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

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

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.

Tigercat 250D Loader LIGHTNING SAFETY In spite of the popular myth that being struck by lightning is an unlikely event, the facts show that lightning strikes occur frequently. As a result loggers are at high risk because their work is outdoors and close to known strike points such as tall trees and heavy equipment.

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

• 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.

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

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

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

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

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

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

1.22

Tigercat 250D Loader

Safety

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

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

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

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

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 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.

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

• 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.

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

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

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

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

• 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.

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.

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

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.

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

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

• Do not use the telephone except for emergencies.

1.23

Safety

Tigercat 250D Loader

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.

• To further increase your awareness about lightning safety, see the following web sites: • National Weather Service Lightning Safety http://www.lightningsafety.noaa.gov • National Lightning Safety Institute http://www.lightningsafety.com

FIRE PREVENTION

• Steam clean the engine, hydraulic pumps, transmission, brake, fuel and hydraulic oil tank compartments and all machine belly pans at least once each month, or more frequently when working in conditions with high volumes of forest debris • Use only non-flammable solutions for cleaning the machine and components.

• Inspect the exhaust system daily for evidence of leakage. Check for worn, cracked, broken, or otherwise damaged pipes or muffler, and missing or damaged bolts or clamps. Make repairs immediately. Engine exhaust leaks can cause fires.

Do not operate the machine until exhaust leaks are repaired.

When working in a forest environment combustible debris will collect in tight corners of the machine. Left unchecked, this debris may cause a fire; when mixed with fuel, oil, or grease in a hot or confined place, the danger of fire greatly increases.

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.

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

• Remove dust and debris regularly from the air intake doors, cooling system components, and A/C condenser to prevent engine and hydraulic system overheating and to maintain efficient operation.

Refer to CLEANING COOLER PACKAGE in SECTION 3 .

• Remove all forest debris and fine organic material around engine intake and exhaust components (turbocharger, exhaust manifold, exhaust pipes, muffler) at the end of each shift, or more frequently when working in conditions with high volumes of combustible forest debris. Check carefully in small pockets and cavities around the engine enclosure where smouldering debris may gather.

NOTE: Minor debris accumulations near hot components can ignite and smoulder. Smouldering debris may shift and cause fire to spread.

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

NOTE: Changes or increases in engine exhaust noise levels often indicate exhaust leaks. Do not ignore these warnings. Shut down the machine immediately and complete repairs.

• 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 the boom raised off the ground. Should the hydraulic cylinder hoses burn through in a fire, hydraulic oil will escape and the boom will fall rapidly to the ground.

• Turn OFF the battery disconnect switch when parking the machine.

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

• Remove the ignition key, and lock the cab and fuel cap at the end of shift to reduce the risk of vandalism or theft.

• Do not smoke in the vicinity of the machine.

• Do not smoke during fuelling operations, when the fuel system is open to the atmosphere, or when servicing the batteries. Exercise caution if smoking in the woods.

• After transporting a machine by road, open all doors and access panels; remove any debris that may have settled around the engine and exhaust system during the journey.

• Before undertaking repair work or welding, clean the surrounding area and place a fire extinguisher within easy reach.

• Inspect the machine regularly for evidence of diesel fuel or hydraulic system leakage. Check for worn or damaged hydraulic and fuel lines before turning on the engine.

• Clean up any grease, diesel fuel, or oil spillage (hydraulic or lubricating) immediately.

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

• Do not operate the machine near burning timber. Do not use the machine to push burning timber into a pile.

• There is no substitute for fire prevention. Time invested in prevention is repaid through productivity on the job site.

1.25

Safety

Tigercat 250D Loader • Workers designated to use fire fighting equipment as part of an emergency action plan must receive full and proper training from a qualified instructor.

NOTICE Equipment fires undermine productive logging, may increase your insurance premiums dramatically, or prevent you from obtaining insurance coverage. Make fire prevention a priority.

• 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.

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

HOW TO PREPARE FOR A MACHINE FIRE

• Know how to use the fire extinguisher, the pressurized water system (as applicable), and the fire suppression system (as applicable) on your machine. There is no time to read instructions during a fire emergency. Be prepared to act.

• Inspect and maintain all machine systems on a routine basis.

• Maintain fire extinguishers in proper working order. Follow the manufacturer’s instructions for inspection and maintenance (on the label of the fire extinguisher and in the user's manual).

• Verify that any pressurized water systems on the machine are charged and in working order. Refer to PRESSURIZED WATER SYSTEM MAINTENANCE as applicable in SECTION 3.

• Verify the correct types of fire extinguishers are available at the work 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.

• Keep emergency contact information readily available in case of fire.

IN CASE OF A MACHINE FIRE If a machine fire occurs: 1. Lower all working attachments to the ground.

2. Turn OFF the engine.

NOTE: If equipped, use the Emergency Stop Button to override the Hot Engine Shutdown Strategy.

Activate the fire suppression system as applicable.

• Class A fires involve ordinary combustibles such as wood, cloth, paper, rubber and many plastics,

3. Radio or call for help. Report a fire immediately.

• Class B fires occur with flammable liquids such as diesel fuel, oil, and grease.

4. Turn OFF the battery disconnect switch if it safe to do so.

• Class C fires apply to energized electrical equipment.

5. Dismount the cab; take the fire extinguisher and pressurized water system hose (if applicable) with you.

• The nozzles on fires extinguishers and pressurized water systems (if applicable) must fit within the fire extinguisher access ports on the machine doors.

• Keep the fire detection system in working order as applicable. Refer to FIRE DETECTION SYSTEM in SECTION 2.

• Keep the fire suppression system charged and in working order as applicable. Refer to FIRE SUPPRESSION SYSTEM in SECTION 2.

• Know the recommended fire procedures in your organization's emergency action plan.

• Follow all national, state/provincial, and local fire fighting regulations. Regulations will vary from region to region but most will require that: • Workers assigned to fire fighting duties must be physically capable of performing them safely and effectively.

6. Put your personal safety and the safety of other persons first. Approach any fire with extreme caution. All fires are potentially very dangerous and life threatening.

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

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

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

If in doubt about your ability to fight the fire, do not attempt to fight it. Stay well back. Wait for help to arrive.

NOTE: Engine coolant, diesel fuel, or hydraulic hoses may fail during a fire. Hot coolant, fuel, or oil could be ignited, or may spray at high velocity from damaged hoses.

1.26

Tigercat 250D Loader

Safety

When fighting a fire:

AFTER A MACHINE FIRE

1. If possible, use a dry chemical fire extinguisher or fire suppression system first.

Before returning a machine to operations:

2. 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 debris or hot machine components in the area. Water cools the area, reducing the chances of re-ignition.

3. Use the fire extinguisher PASS method:

1. Determine the cause of the fire.

2. Complete all necessary repairs.

3. Service and recharge the fire suppression and detection systems as applicable.

4. Report the fire to your dealer and/or Tigercat Industries Inc. by completing an incident report (Tigercat form 5101).

Pull the safety pin at the top of the extinguisher that prevents the discharge lever from being depressed.

Break the plastic seal as the pin is pulled.

NOTE: Fire detection systems are offered as optional installations on some Tigercat product lines. Please disregard any references made to fire detection systems if not installed on your machine.

Aim the nozzle at the base of the fire. Do not aim the nozzle at the flames. To put out the fire, the fuel must be extinguished, not the flames. Hose nozzles are often clipped to the extinguisher body. Release the hose before taking aim.

NOTE: Dry and wet chemical fire suppression systems are offered as optional installations on some Tigercat product lines. Please disregard any references made to fire suppression systems if not installed on your machine.

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

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

822C-190

Typical Fire Extinguisher Access Port

4. Insert the fire extinguisher nozzle into the appropriate access port and discharge the extinguisher.

5. If it is safe to do so, open the access panels in the area of the fire and aim the extinguisher directly at the base of the flames.

6. If it is impossible to reach an access port or to open a panel or door, discharge the extinguisher through mesh screening or any available opening.

7. Monitor the machine after extinguishing a fire in case of re-ignition; remain until help arrives.

DRY CHEMICAL CLEANUP PROCEDURES

WET CHEMICAL CLEANUP PROCEDURES

ABC dry chemical fire extinguishers and fire suppression systems discharge a chemical powder. The powder comprises very fine particles that penetrate and cover all components in the vicinity of the discharge.

The wet chemical suppression fluid contains frost protection, rust inhibitor, and film-forming liquids that are broken down by natural organisms. When the fluid dries, the corrosion protection loses its effect. Clean up wet chemical discharges as soon as possible to avoid corrosion on metal parts.

Areas in contact with dry chemical power must be neutralized and cleaned after a fire. Wear protective clothing, safety goggles, and a fine particle dust mask.

1. De-energize electrical systems prior to any cleanup.

2. In areas that remained cool and dry during the fire, the dry chemical remains in powder form.

Clean these areas immediately to prevent residual powder from coming into contact with water or ambient moisture.

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.

Wipe all surfaces with a damp cloth.

3. In areas exposed to moisture during the fire, the dry chemical powder combines with water to form a paste that is mildly acidic. All surfaces covered in dry chemical paste, including electrical contacts, are vulnerable to corrosion.

Neutralize the acidic paste on large surfaces by spraying or washing these areas with a mixture of three parts hot water to one part baking soda. Allow this mixture to stand for several minutes before rinsing with warm water. Wash the area with a mild soap and water solution. Rinse thoroughly with water. Blow-dry to remove all residual water.

If the suppression fluid is sucked into the engine air intake, it will not significantly change engine functioning.

However, starting difficulties may occur with diesel engines because the suppression fluid contains water.

The suppression fluid also may cause corrosion damage if the engine is not cleaned soon after a fire.

Clean affected areas promptly to protect electrical system functions and prevent short circuits.

To clean affected areas: 1. Flush the affected area with pressurized fresh water.

2. Use an alkaline washing detergent to remove the film. (Film residue attracts dirt and other impurities on affected surfaces.)

3. Flush affected areas a second time to remove detergent residue.

NOTICE To protect engines, electrical installations, and other metal parts against corrosion, flush the remains of dried or moist suppression fluid as soon as possible after the release of the piston accumulator (use a high pressure washer if possible).

Clean electrical contacts with a contact cleaner that has no flash or fire point and is non-corrosive and non-conductive, such as CRC Contact Cleaner 2000.

4. In areas exposed to heat during the fire, the dry chemical powder melts, 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.

When exposed to moisture the caked dry chemical is also mildly acidic. When the breakdown procedure has been completed, follow this immediately with the neutralizing procedure as described in step 3.

FAN CONTROL SWITCH – VARIABLE PITCH FAN (OPTIONAL) A B C

NOTE: When the switch is in the AUTO position and the fan has stopped due to low charge air, engine coolant and hydraulic oil temperatures; turning ON the A/C will cause the computer system to immediately place the fan blades at a pitch to provide 30% air flow. This is to ensure that sufficient air flow is available for the cab A/C even while the machine is still warming up.

FULL ON POSITION 724G-011

A Full ON B Auto C Clean (Purge)

This is a three-position momentary switch, FULL ON/ AUTO/CLEAN. This switch controls the operation of the Flexxaire® cooling fan.

The cooling fan blade pitch is hydraulically varied to control the flow and direction of air through the cooler package

AUTO POSITION

A

2000123

A Fan Icon – Full On Position

When the switch is in the FULL ON position, the computer control system is overridden and the fan will run at FULL air flow (blades pitched to 100%), for cooling regardless of charge air, engine coolant or hydraulic oil temperatures. Normally the fan control switch is placed in the AUTO position for optimal cooling. The FULL ON position is intended for use in the event of a temporary failure of the control system.

CLEAN POSITION

2000087

A Fan Icon – Auto Position

AUTO is the normal operating position for the fan control switch. When the switch is in the AUTO position, the fan will operate completely in an automatic mode. The computer control system will automatically control the fan pitch to minimize system energy losses and improve performance based on the temperature of the charge air, engine coolant and hydraulic oil. The computer system automatically adjusts fan air flow to the minimum required level to maintain optimal operating conditions.

Automatic control of fan air flow to match the operating conditions can lower fuel consumption and reduce operating costs. In high temperature operating conditions the fan air flow is increased to improve cooling ability and efficient operation of the cooler package and air conditioning systems. In low temperature operating conditions fan air flow is reduced, as less cooling is required for efficient operation of the cooler package.

In addition, when this switch is in the AUTO position, the system will automatically cycle through an auto clean cycle.

The fan auto clean cycle is adjustable through the computer control system menu. Refer to COMPUTER – MAIN MENU – ADJUST MENU – FAN in THIS SECTION.

A 2000122

A Fan Icon – Clean Position

Momentarily pressing the switch to the CLEAN position will manually start the automatic clean cycle, reversing the flow of air (there is no need to hold the switch down).

The pitch of the fan blades is changed and the direction of airflow through the engine enclosure is reversed. This change in airflow blows debris from the machines engine enclosure to eliminate potential overheating and poor machine performance caused by overheating. Ensure there are no personnel standing directly to the sides of the machine when performing this operation, as dust and debris will fly out.

When the CLEAN cycle is complete the fan automatically returns to normal air flow direction.

It is also important to manually clean debris from the machine on a regular basis to maintain low machine operating temperatures. Refer to CLEANING COOLER PACKAGE in SECTION 3.

RIDES TOO SOFT OR BOTTOMS OUT AND PINCHES OPERATOR The ride control knob has under tensioned the seat spring Insufficient tension 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 spring tension instead of using the height adjustment lever.

SEAT TOO HIGH/SEAT TOO LOW 200182

A Heater /Vent Switch B Low/Med/High Switch

The heater/vent switch is a three-position switch. The up position turns the seat heater ON and the down position turns the seat vent ON. The middle position is OFF. The low/med/high switch is also a three-position switch and adjusts the heat level or vent speed depending on the mode selected.

2.31

There are several things which can cause improper seat height. Adjust seat to the desired position. If the proper height cannot be reached using one of the four height adjustment settings, it may be necessary to install the seat on a higher base.

OPERATOR’S LEGS FALLING ASLEEP The seat is adjusted too high, and the ride control adjustment knob has under tensioned the seat spring, resulting in the operator sitting in a 'bucket'.

LOG IN Some service operations require user name and password access.

ON-SITE MODE

NOTE: Data charges may apply.

GET CLONE

The IQAN-G11 module works in two modes:

Get and save the existing application, settings, and machine ID from the computer for backup purposes before tuning or updating the program.

• On-site mode • Remote Assistance mode The On-site mode allows the operator to view machine data in real-time through their mobile device. The operator can also download machine files to the smart phone and forward the stored files to a computer in separate location for further review. Similarly, the service technician may send the operator machine settings and updates to upload to the machine remotely.

The Remote Assistance mode allows the operator to directly connect the machine with a service technician from a remote location to perform operations and diagnostics to the machine.

GET SETTINGS Acquire and save the existing settings from the computer for backup purposes before tuning or updating the program.

GET LOGS Access logs for troubleshooting, maintenance documentation, or clearing. Some log operations require username and password access.

FORWARD DATA Send previously saved machine programs, settings and logs to the service technician for further review.

RECEIVING DATA Receive updated programs and settings from the service technician to load to the machine using the app.

SEND TO MACHINE Send a program, clone or settings file to the computer.

This overwrites factory defaults, adjustable and stored values. Perform this operation only under direction from the Tigercat Service Department.

ENGINE, RESTARTING AFTER ENGINE RUNS OUT OF FUEL

STOPPING ENGINE

1. Fill the fuel tank completely.

2. Bleed the system according to the procedures in the ENGINE OPERATION AND MAINTENANCE MANUAL.

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

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

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

IMPORTANT! Stopping the engine immediately after it has been working under load can result in overheating and premature wear of the engine components. Follow the stopping procedure outlined below to allow the engine to cool. The important benefits are: • Extended life of engine, cooling and exhaust systems.

• Reduced risk of post shutdown fires.

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

1. Fully supported the grapple and booms by lowering the grapple onto the trailer, carrier or stable ground.

2. Reduce engine speed to LOW, deactivate the pilot system by raising the left armrest and let the engine run at LOW speed for approximately three minutes (minimum) to allow dissipation of heat and also to reduce turbo speed. This will also prevent loss of coolant by after boil and possible hot spot damage to the engine.

Do not increase engine speed before turning it OFF. 3. Place all controls in neutral positions and turn OFF all accessories and functions.

4. Turn OFF the engine.

5. Remove the ignition key.

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

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

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

7. Perform EVERY 8 HOURS maintenance at the end of the shift (greasing, clean engine compartment, etc.). This allows the machine time to cool down while under the watchful eye of the operator.

MACHINE PREPARATION SYSTEM TEST AND WARM-UP

11. Test all accessory equipment including delimber, top saw, slasher saw etc.

NOTE: The right joystick button performs two separate functions depending on the status of the delimber arms. With delimber arms closed the button operates the top saw. With the delimber arms open the button operates the slasher saw.

Prior to commencing any loading operations follow steps 1 – 15 to accomplish the following: • Warm up the hydraulic system.

• Test all systems for proper operation.

• Inspect for hydraulic oil leaks.

IMPORTANT! If any system or function fails to respond correctly to the controls, stop the machine preparation procedure and notify a mechanic. Failure to do so may result in damage to hydraulic pumps and other components.

1. Perform PRESTART CHECKS, STARTING ENGINE and SETTING THE MACHINE procedures in THIS SECTION. 2. Sound the horn to warn personnel of machine startup.

12. Continue testing and operating various functions until engine and hydraulic oil has warmed up to near normal operating temperatures. Never load the machine until it has sufficiently warmed up. Doing so may cause damage to the engine and hydraulic components.

13. Lower the grapple onto the trailer, carrier or stable ground ensuring grapple and booms are fully supported.

14. Set engine speed at LOW. 15. 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.

Tigercat 234B Loader

Controls and Operation

OPERATING TIPS WITH LOAD SENSING 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.

Load sensing systems respond to rough operation by amplifying these movements. If you find the boom is jerky or 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 LOAD SENSING– SET MARGIN PRESSURE in SECTION 4 of the SERVICE MANUAL.

DANGER Moving stabilizers can cause serious injury or death. Ensure area is clear of all personnel prior to operating stabilizers.

The loader must be located and firmly set in place prior to operating.

Refer to following steps to ensure safe operation:

D

1. Locate the loader on firm level ground only.

2. Lower the stabilizers to set them firmly on stable ground. If the loader is mounted to a trailer, the stabilizers should be used to raise the rear of the trailer off the ground. Ensure loader is sufficiently stable to perform all log loading operations.

3. Lower the stabilizers so the weight is just taken off the trailer or carrier tires and the loader is level. The machine should not be operated with the stabilizer cylinders fully extended; they should have at least 25 mm (1/2 in) of unused stroke so the counterbalance valves may relieve pressure build up caused by an increase in temperature.

WARNING An unstable loader can cause severe injury, death or property damage. Do not operate unless stabilizers have been lowered and set firmly on stable and level ground.

TIGERCAT FLUID ANALYSIS PROGRAM

TIGERCAT FLUID ANALYSIS KITS

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

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

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

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

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

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

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

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.

TIGERCAT FLUID SAMPLING PROGRAM

HYDRAULIC OIL SAMPLES

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

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

Collection of clean fluid samples that are representative of the main body of fluid are essential if meaningful lab results are to be obtained. Erroneous readings may result if proper collection, handling, packaging and shipping practices are not followed prior to the sample being tested by the lab. To be able to accurately compare and trend the lab results over time, all followup samples should be consistently taken from the same location using the same techniques as all previous samples.

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

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

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

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

A

200560

A Hydraulic Oil Sample Valve – On Hydraulic Oil Return Manifold

• 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.

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

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

TRANSMISSION, GEARBOX AND AXLE SAMPLES: • These samples can be taken during the oil change process.

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

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

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

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

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

• 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.

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

GENERAL

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

CAUTION

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

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

• 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. Repair all exhaust leaks or defective parts immediately. Engine exhaust leaks can cause fires. Do not operate the machine until the exhaust leak is repaired.

• Clean around fill caps before checking or adding fluids.

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

• 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. When exhaust leaks occur during operation, shut down the machine immediately and do not put it back to work until the necessary repairs have been completed.

• 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.

• Always have a fire extinguisher at hand.

• Clean up oil spills in engine enclosure immediately.

• Always lower the boom assembly to the ground when leaving the cab, leaving the machine unattended or when performing servicing procedures.

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

• Check and clean the fire detection system sensors on a regular basis.

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

Tigercat 234B Loader FIRE EXTINGUISHER

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

A

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

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

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

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

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

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 grapple to the ground and turn OFF the engine before discharging the fire suppression system.

234-095

A Charge Gauge

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

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

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

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

Air Vent Check Valve Vacuum Sensing Switch Vacuum Pump Solenoid Valve Air Vent Breather Hydraulic Oil 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 oil 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 oil tank before servicing the system.

NOTE: When the ignition key switch is in the RUN position, the vacuum pump system will not start. When the vacuum pump is on, the engine cannot be started.

IMPORTANT! Do not use the vacuum pump when changing hydraulic filters. 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.

NOTE: Depending on the type of maintenance performed with the vacuum pump system ON, it will be necessary to bleed air from the hydraulic system. Refer to START-UP PROCEDURE AFTER MAJOR MACHINE MAINTENANCE in THIS SECTION.

NOTE: This switch will not function with the battery disconnect switch is in the OFF position.

A Vacuum Switch

This switch is located in the front engine compartment.

It is 'unswitched' and WILL function with the battery disconnect switch in the OFF position. Push the right side of the switch to put it in the ON position to activate the vacuum pump.

Activating the pump will create a vacuum condition (9 in. Hg) in the hydraulic oil 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.

Do not attempt to start the machine or turn the ignition key switch to the RUN position.

Lubrication and Maintenance REFILLING THE HYDRAULIC SYSTEM

Tigercat 234B Loader HYDRAULIC OIL RETURN FILTERS

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.

B

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

A

D

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 HYDRAULIC SYSTEM – ADDING 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 especially the variable pitch cooling fan (if equipped) for proper operation after hydraulic oil has been replaced.

Return Filter Manifold Filter Restriction Pressure Switch Hydraulic Oil Return Filters (White) – Quantity 2 Water Absorbing Return Filter (Blue) – Quantity 1

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

For service and replacement intervals refer to SCHEDULED MAINTENANCE in THIS SECTION. There is a bypass valve, preset at 1.7 bar (25 psi), built into each filter head, which will open when the filters become restricted. Before the valve is activated a filter restriction pressure switch will cause the Hydraulic Oil Return Filter Bypass icon on the computer display to illuminate RED. Refer to HYDRAULIC SYSTEM – FILTER RESTRICTION PRESSURE SWITCH in THIS SECTION.

IMPORTANT! Do not use these warnings as a substitute for changing the hydraulic oil return filters at regular intervals as per SCHEDULED MAINTENANCE in THIS SECTION. This information is assuming that operating conditions and running temperatures are normal.

HYDRAULIC FILTER SERVICING GUIDELINES

NOTICE Do not pre-fill hydraulic filters.

Tigercat does not recommend the pre-filling of spinon 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 valves, pumps and motors.

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

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

When replacing air conditioning system components, it is important to replace PAG oil that has been lost when parts are changed. The total amount of PAG oil added to compensate for replacement components should not exceed the total capacity.

When recharging the system, only add the quantity of oil reclaimed during the recovery process.

Low PAG oil levels can starve the compressor for oil and lead to compressor failure. Too much PAG oil can hurt the cooling performance.

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

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

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

The compressor and charge ports are accessed through the front engine compartment door.

CONDENSER The condenser is part of the cooler package.

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

Refrigerant flows through the condenser tubing from top to bottom. The high internal pressure coupled with the large volume of air cooling the condenser as it passes over the condenser core produces a condition in which vapour refrigerant converts to liquid refrigerant (condensation). This change usually takes place in the bottom third portion of the condenser.

ENGINE FILTERS – REMOVE AND REPLACE

IMPORTANT! Failure to service and replace engine filters at the proper intervals specified in the ENGINE OPERATION AND MAINTENANCE MANUAL could cause damage to the machine and result in the product warranty becoming null and void. Check the Tigercat parts catalog for replacement filters.

Tigercat 234B Loader FUEL FILTERS These engines use filters with a very fine micron rating.

If the fuel supply is dirty, the fuel filter must be replaced more frequently than recommended in SCHEDULED MAINTENANCE in THIS SECTION. Operating the machine with a clogged fuel filter will result in low engine power. It is also recommended to drain the fuel filter/ water separator bowl daily.

NOTICE

Refer to the appropriate ENGINE OPERATION AND MAINTENANCE MANUAL for the oil and fuel filter replacement procedure. Read and understand the SAFETY section in each of THESE MANUALS.

ENGINE OIL FILTER

A

200565

A Engine Oil Filter

The engine oil filter is located on the rear of the engine.

It is accessed through the engine compartment rear access door.

When installing a new oil filter, Do not pre-fill with engine oil as this may result in engine damage. This type of failure is not warrantable by the engine manufacturer.

Tigercat does not recommend the pre-filling of spin-on filters due to the risk of damage to the fuel system caused by unfiltered fuel. Unfiltered fuel used to pre-fill filters enters directly into the fuel circuit. Contaminants in unfiltered fuel can cause significant and costly damage to fuel system components. The cleanliness of fuel cannot be guaranteed unless it is pre-filtered before use.

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.

To prolong the operating life of the fuel filter, the fuel supply storage tank must be clean and free of water and the fuel must be pre-filtered prior to adding it to the machine.

AIR INTAKE SYSTEM

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

ENGINE AIR PRECLEANER

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.

T250D-033

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.

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

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.

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.

A

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

B

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.

C

200556

A Air Cleaner B Air Intake Filter Restriction Indicator C Air Cleaner Unloader Valve

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.

B

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.

A 726D-006

A Primary Element B Secondary (Safety) Element

The air cleaner on this machine uses two filter elements, a primary element and a secondary (safety) element.

It is accessible through the engine compartment front access door.

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

3.61

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 Cleaner Unloader Valve

Check the rubber air cleaner unloader valve on the air cleaner housing every 8 hours. If this valve is missing, damaged or has become hard, it will cause the air cleaner to become ineffective.

Replace the unloader valve every 1000 hours.

Remove the unloader valve from the tube of the air cleaner housing. A good valve should be soft and flexible. Check and clean the valve. If it is plugged, check the filter elements as they may also need to be replaced. Reattach the valve to the tube. The valve should suck closed at about one-third of HIGH engine speed. When operating in high dust conditions this valve should be checked and squeezed every two hours to release dust buildup.

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! 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.

3.63

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.

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.

The heater valve is mounted on the frame directly under the engine. Access it from underneath the rear of the machine.

The heater valve controls the flow of engine coolant through the DEF tank heater coil and the supply module when heating of the DEF is required. The heater valve also controls the constant flow of engine coolant to the dosing module for cooling purposes. This machine is equipped with electrically heated DEF supply lines.

IMPORTANT! If removing the heater valve care should be taken to reconnect the cooling hoses correctly. The heater valve is directional and if the hoses are connected incorrectly the DEF may overheat which will reduce its quality.

DEF freezes at −11°C (12°F).

Temperature sensors signals control the operation of both the electrically heated DEF supply lines and the heater valve which, depending on the temperature, opens or closes the flow of hot engine coolant to the heater coil and supply module.

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.

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).

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

3. Remove any accumulated debris.

4. Use compressed air or water for cleaning.

CAUTION

Tigercat 234B Loader NOTE: The cooler package must be checked daily and may have to be thoroughly cleaned on a daily, weekly or monthly basis, depending on operating conditions.

Use personal protective equipment (eye wear) to guard against flying debris. Use compressed air for cleaning only when the machine is cold to avoid the risk of fire caused by debris contacting hot surfaces. Care must be taken not to set the pressure too high otherwise damage to the components could result.

Pay particular attention to cleaning in the corners of the cooler as these areas usually plug deeply.

Reversing the fan at least once per hour will help reduce the dust accumulation in the cooler cores. Refer to SWITCHES – FAN CONTROL – VARIABLE PITCH FAN (OPTIONAL) in SECTION 2 to manually reverse the fan. The auto clean cycle is adjustable through the computer control system menu. Refer to COMPUTER – ADJUST MENU – FAN in SECTION 2.

For more information on fire prevention refer to FIRE PREVENTION in SECTION 1.

If an oil leak occurs in this area it should be thoroughly power-washed with a mild soap to ensure 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.

Use compressed air for cleaning only when the machine is cold to avoid the risk of fire caused by debris being blown into contact with hot surfaces.

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

Always use personal protective equipment (eye wear) to guard against flying debris.

5. When the units have been cleaned return all cooling components to their operating position.

CAUTION Avoid the risk of fire caused by debris accumulating on surfaces that may become hot during machine operation. Always use care when cleaning to ensure debris removed from one area of the machine does not accumulate on other areas of the machine.

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

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

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

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

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

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

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

• 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.

Brand name soaps and detergents recommended for cleaning polycarbonate are:

• Ammonia • 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 • 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 the higher the water temperature, the shorter the time before the polycarbonate is adversely affected.

• Top Job 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.

Lubrication and Maintenance GRAFFITI REMOVAL

CAUTION • Do not use abusive cleaning procedures

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

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

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

either by hand or pressure washing on polycarbonate windows.

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

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.

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

FIRE PRECAUTIONS

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

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.

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

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

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.
