Tigercat 250C Loader

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

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

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

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

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

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

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

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

•

If these are found, Do Not Touch!!!

•

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

•

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

•

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

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

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

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.

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

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

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

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.

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

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.

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

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

• Seek professional medical attention immediately.

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

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

Always wear thick protective gloves.

• Be sure to wear safety goggles for eye protection.

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

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

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

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

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

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

•

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

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

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

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

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

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

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.

SERVICING SAFETY PRECAUTIONS continued GREASE INJECTION INJURY WHEN USING PNEUMATIC GREASE GUNS Pneumatic grease guns can deliver grease at pressures from 17 – 400 Bar (246 – 5801 psi).

It takes less than 7 Bar (100 psi) to inject a substance through human skin.

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

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

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

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

All operators of high pressure pneumatic grease guns MUST be trained in the hazards of its operations and the treatment for such injuries.

•

DO NOT OPERATE a high pressure pneumatic grease gun unless you have been trained in the proper operation and are aware of all safety precautions of such a tool.

•

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

•

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

•

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

•

Remove dirt and grease from grease fittings prior to greasing.

•

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

•

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

Safety LIGHTNING SAFETY

LIGHTNING SAFETY AWARENESS

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

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

1.

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.

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.

2.

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

3.

Anticipate a high-risk situation and take action early by moving to a low-risk location.

Do not hesitate. If there is lightning, you are in danger.

4.

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.

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

5.

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

6.

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

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.

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.

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.

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

1.17

Tigercat 250C Loader

Safety WHAT TO DO IF YOU ARE OUTSIDE AND SEE LIGHTNING OR HEAR THUNDER. If you can, get inside.

1.

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

2.

If inside a building:

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

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

•

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

•

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

3.

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

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

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.

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.

•

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.

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

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

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

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

1.18

Tigercat 250C Loader

Safety What to do if you feel your skin tingling, your hair stands on end, light metal objects vibrate or you hear a crackling sound.

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

1.

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

2.

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

3.

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

1.

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

2.

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

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

3.

Get away from open water such as ponds or streams.

1.

4.

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

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

5.

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

2.

Call your local emergency response telephone number immediately.

6.

Avoid entering any small enclosures or shelters.

3.

7.

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

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

Use a portable defibrillator if one is available.

8.

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

4.

9.

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

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

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

FIRE PREVENTION

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

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

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

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

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

4.

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

5.

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

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

6.

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

7.

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

Use only nonflammable solutions for cleaning the machine and components.

8.

9.

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

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

10. During daily operation of the machine, the occurrence of exhaust leaks are usually accompanied by a change or increase in engine exhaust noise levels. These audible warnings cannot be ignored.

Should any exhaust leaks occur during operation, the machine must be shut down immediately and not put back to work until the necessary repairs have been completed.

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

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

1.20

Tigercat 250C Loader

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

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

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

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

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

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

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

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

•

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

•

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

•

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

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

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

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

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

Ensure that your fire suppression system** is charged and in working order. Refer to FIRE SUPPRESSION SYSTEM in SECTION 2 of the OPERATOR’S MANUAL. Ensure that you are familiar with the recommended procedures for fire contained in the emergency action plan of your company.

Ensure that you follow all national, state / provincial and local regulations dealing with fire fighting in effect in your specific geographic region. Regulations will vary from region to region but most will usually require that: 1. Workers assigned to fire fighting duties must be physically capable of performing them safely and effectively.

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

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

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

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

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

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

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

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

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

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

6. If possible a dry chemical fire extinguisher or fire suppression system** should be used first to fight a machine fire.

Then immediately afterwards use the pressurized water hose supplied with the machine (if applicable) or a pressurized water extinguisher (if available). A fire suppressed by dry chemical may re-ignite from the heat retained by any debris or hot machine components in the area.

The water will cool the area, reducing the chances of re-ignition.

DRY CHEMICAL CLEANUP PROCEDURES

3.

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

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

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

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

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

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

1.

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

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

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

2.

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

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

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

Wash the area with a mild soap and water solution. Rinse thoroughly with water. Blowdry to remove all residual water.

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

ELECTROHYDRAULIC CONTROL VALVES

XA2 EXPANSION MODULE

PILOT CONTROL VALVES

250C-004

Electronic joysticks use electrical signals to turn on electric solenoid controls that activate the main control valves for the boom and grapple functions.

Other switches on the joysticks and instrument panel are used to operate the remaining control valves such as slasher and delimber functions if equipped.

SOLENOID CONTROLS

The main valve is supplied with oil from the main pump. The valves receive oil at the inlet section of the main control valve and direct the oil through the spool sections when either of the joysticks are activated.

Moving either of the joysticks will send an electronic signal to the MD3 computer module.

The signal is then directed to the XA2 expansion module and from the module the signal is directed to the solenoid control for the function that is selected.

234-051

CONTROL VALVE SECTION

The electrical signal activates the solenoid and opens a pilot circuit that directs internal pilot oil to the spool actuator of the control valve selected.

This shifts the spool of the control valve directing pump oil flow to the selected function.

2.26

Tigercat 250C Loader

Controls and operation

ELECTRONIC JOYSTICK FUNCTION Components and Operation: When not actuated the lever (1) is held in neutral position by the return springs (8). When operating the lever (1), the plunger (5) pushes against return spring (8). The magnet (7) mechanically linked to the plunger (5) moves upward or downward while following the levers actuation direction. The electrical signal generated by the sensor (4) is proportional to the deflection of the lever. A rubber boot (6) protects the mechanical components of the housing from external contamination.

MAIN VALVE SPOOL SECTIONS All of the main valve spool sections are equipped with proportional electro-hydraulic solenoid controls. The spools are spring centered to the neutral position. Sending an electrical signal to the desired electro-hydraulic solenoid control causes the solenoid to shift and direct internal pilot oil to the chosen spool actuator shifting the spool and directing pump oil flow to the selected cylinder or motor.

PROBLEMS AND CORRECTIVE ACTION

HEIGHT ADJUSTMENT.

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

Refer to height adjustment.

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

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

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

Tigercat 250C Loader INHIBIT – Inhibit (REGEN DISABLE) This mode disables active regeneration of the diesel particulate filter. This allows the operator to Permit or Inhibit automatic regeneration of the diesel particulate filter. This will occur while the machine is running without warning or requiring acceptance from the operator.

Controls and operation AFTER TREATMENT DEVICE OPERATION Engine Work Cycles and the affect on the DPF System: During typical machine operation the engine works at high idle with a continuous load on the engine. During this type of operation (Working Duty Cycle) the engine performs a passive regeneration of the DPF system cleaning the filter continuously.

However, if the engine is operated at low idle and light loads (Light Duty Cycle) for an extended period the engine can not perform a passive regeneration, trapped soot particles accumulate in the filter and an active regeneration will be required to clean the filter.

To ensure optimum performance of the DPF filter and engine, the diesel particulate filter system monitors engine exhaust pressure and temperature and alerts the operator via the DPF Icon on the display unit and alert and critical warning messages are displayed when the DPF filter needs cleaning.

Pressing the F2 button on the engine menu page will launch a menu box. Toggle between the selection using the up/down keys and accept a selection using the OK key. Once it is initiated only the pilot reset switch being activated or shutting off the engine will interrupt an active regeneration.

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

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

AIR FILTER RESTRICTION INDICATOR A filter restriction indicator is located in the engine enclosure beside the air cleaner. The indicator is remote mounted and is connected to the outlet side of the air filter with a hose. Replace the primary air filter when the restriction indicator shows RED. This indicator provides a continuous reading whether the engine is running or is shut down. After replacing the filter, reset the indicator by pressing the reset button.

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

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

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

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

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

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

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

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

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

IMPROPER SERVICING Engine exposure to dust during servicing is the largest single factor contributing to engine damage due to dust. Abrasive dust can easily enter the intake system once the air cleaner element has been removed for replacement. The safety element reduces the risk, however it must also be replaced at every third primary element change.

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

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

4. Always clean the inside of the housing.

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

6. Inspect the new filter for damage.

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

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

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

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 malfunction of the machine's equipment may make towing necessary.

Towing is only recommended over short distances. It is always better to make repairs at the point where the machine is parked whenever possible.

3. Park the grapple in its proper location on the carrier. Turn off the engine.

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

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

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

Polycarbonate windows are an essential piece of operator protective equipment and should be maintained as such. It is important to note that cracks, chips, notches or scarring anywhere on the viewing surface or edges of the window will decrease ability to resist heavy impacts and therefore compromise effectiveness as operator safety protective equipment. Windows with these defects must be replaced immediately.

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

2.98

Tigercat 250C Loader INSPECTION AND MAINTENANCE Daily inspection and maintenance is essential to confirm that the window’s ability to protect the operator has not been compromised.

• Inspect all windows daily and immediately after any impacts.

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

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

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

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

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

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

Windows with these defects must be replaced immediately.

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

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

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

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

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

Other chemicals however can seriously weaken the polycarbonate.

DO NOT permit any of the following chemicals to come into contact with polycarbonate windows: • acetone • air conditioning refrigerant • ammonia • anti-freeze • benzene • brake fluid • carbon tetrachloride • cutting oils • gasoline • lacquer thinner • toluene • turpentine • xylene RESISTANCE TO WATER Polycarbonate material has good resistance to water up to approximately 65°C (150°F). Above this temperature the effect of water is timetemperature related. This means that the higher the water temperature, the shorter the time before the polycarbonate is adversely affected.

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.

CLEANING INSTRUCTIONS

CAUTIONS

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

•

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

•

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

•

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

•

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

•

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

•

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

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

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

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

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.

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

FILTER RESTRICTION INDICATOR

OIL SAMPLING CONNECTOR 250CT-012

HYDRAULIC OIL RETURN MANIFOLD

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

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

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

•

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

•

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

• •

•

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

•

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

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

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

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

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

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

3.4

•

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

•

Place the required drain container under the machine to capture the used oil.

•

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

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

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

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

SLIDING WINDOW HANDLE

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

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

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

For service and replacement intervals see SERVICE AND LUBRICATION CHART in THIS SECTION. Changing the filter or strainer: 1. Ensure Loader is on level ground with stabilizers down. Lower grapple to ground and stop engine.

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

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

250CT-015

4. Wearing face protection (in case of an oil squirt), unscrew the old filter. Dispose of old filter and any oil properly.

CASE DRAIN STRAINER

CASE DRAIN STRAINER The case drain strainer is used to filter all case drain oil from the pumps and motors before it returns to the reservoir.

The strainer element requires no regular maintenance over the life of the machine. This element requires maintenance only in the case of damage or contamination due to a hydraulic pump or motor failure.

IMPORTANT! The strainer element is NOT a filter element.

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

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

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

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

8. Turn filter an additional 1/2 turn by hand to tighten. DO NOT use bottom nut for filter installation or damage/leakage may result.

Bottom nut is to assist in filter removal only.

9. Start the engine and check for leaks.

IMPORTANT! Contaminated hydraulic fluid can lead to premature failure of hydraulic components and costly repairs.

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

AIR CLEANER

AIR CLEANER UNLOADER VALVE

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

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.

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

AIR FILTER RESTRICTION INDICATOR A filter restriction indicator is located in the engine enclosure beside the air cleaner. The indicator is remote mounted and is connected to the outlet side of the air filter with a hose. Replace the primary air filter when the restriction indicator shows RED. This indicator provides a continuous reading whether the engine is running or is shut down. After replacing the filter, reset the indicator by pressing the reset button.

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

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

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

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

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

ENGINE COMPARTMENT FRONT ACCESS IMPORTANT STEPS TO FOLLOW WHEN CHANGING FILTER ELEMENTS

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

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

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

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

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

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

3. Check your old filter sealing surfaces. This will help detect if foreign material on the sealing surface caused leakage.

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

IMPROPER SERVICING Engine exposure to dust during servicing is the largest single factor contributing to engine damage due to dust. Abrasive dust can easily enter the intake system once the air cleaner element has been removed for replacement. The safety element reduces the risk, however it must also be replaced at every third primary element change.

4. Always clean the inside of the housing.

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

6. Inspect the new filter for damage.

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

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

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

CHECKING AIR CONDITIONING SYSTEM

CAUTION

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 5 minutes every two weeks to circulate oil to all components of the system.

R134a REFRIGERANT

PAG OIL (polyalkylene glycol)

1.25 kg (3 lb 6 oz)

74 mL (2.5 oz)

Any service work must be performed by authorized A/C technicians. The system should be charged with R134a refrigerant. At least the minimum amount of PAG (polyalkylene glycol) oil, shown above, should be present in the system and must be used on O-rings and fittings during assembly.

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

Always use personal protective equipment to guard against flying debris.

Use the following checklist to maintain system between service intervals. The compressor and charge valves are located on the left side of the engine and accessible through the engine compartment door. The receiver dryer is located in the lower engine compartment beside the front left engine mount and accessible from either underneath the engine compartment or through the engine compartment door.

Perform the following checks on system: a. Check and adjust compressor drive belt tension. Do not over tighten. b. Check fresh air filter and re-circulating air filter.

Clean or replace as required. c. Check to see that compressor clutch will engage. d. Check blower operation and air vents.

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

Always use personal protective equipment to guard against flying debris.

250CT-019

CHECK CHARGE AIR COOLER, RADIATOR, A/C CONDENSER AND OIL COOLER The cooler package should be manually checked every 8 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.

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 assembly, as the components can be damaged by careless handling and cleaning.

Lubrication and Maintenance

Parker

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

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

• Four bolts and washer

WASHERS BOLTS FLANGE CLAMP

Flange Port Assembly

FLANGE HEAD

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

2. Lubricate the O-ring.

3. Position flange and clamp halves.

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

5. Hand tighten bolts.
