Introduction

S.A.E. STANDARDS ROLL-OVER PROTECTION STRUCTURES (ROPS) FALLING OBJECTS PROTECTION STRUCTURES (FOPS) OPERATOR PROTECTION STRUCTURES (OPS) * MODIFICATIONS AND REPAIRS:

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

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

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

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

ii) Approved modifications officially released by Tigercat.

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

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

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

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

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

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

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).

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

1.6

Tigercat 615C Skidder

Safety

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

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.

Even though the brakes are fully engaged, block the wheels to prevent movement during transport.

Install articulation lock whenever the machine is to be transported.

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.

Safety

FLUID INJECTION INJURY

WARNING

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.

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

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

• 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.

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.

•

Time becomes critical as tissue damage progresses rapidly. The longer you delay getting professional medical attention, the more damage can occur.

Although fluid injection accidents are rare, the resulting injury has on occasion required the amputation of a finger, a hand or in some cases the entire limb. The longer the delay in getting professional medical aid, the further up the limb the tissue damage can spread. An injury of this type can become very serious or even fatal if not dealt with promptly and properly.

1.17

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

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

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

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.

Tigercat 615C Skidder

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.

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

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

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

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

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

•

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

•

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

•

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

•

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

•

Remove dirt and grease from grease fittings prior to greasing.

•

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

•

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

Safety LIGHTNING SAFETY

LIGHTNING SAFETY AWARENESS

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

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

1. Designate a member of your crew to

WHAT IS A LIGHTNING STRIKE? 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.

•

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.

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

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

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.

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.

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

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

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

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

1.19

Tigercat 615C Skidder

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.

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

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

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

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

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

1.20

•

Under no circumstances whatsoever step outside of the vehicle or off the equipment to move to another shelter. Very dangerous electrical pathways to ground may go through you.

•

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

•

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

•

Do not touch any metallic objects referenced to the outside of the vehicle.

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

•

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

Tigercat 615C Skidder

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

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

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

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

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

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

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

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

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

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

2. Call your local emergency response telephone number immediately.

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

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

Use a portable defibrillator if one is available.

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

6. Avoid entering any small enclosures or shelters.

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

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

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

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

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

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

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

11. Do not use the telephone except for emergencies.

Safety 4. Clean out all accumulated forest debris (twigs, pine needles, branches, bark, leaves, saw dust, small wood chips) and any other combustible materials from inside the machine belly pans or lower machine structures as well as from areas in proximity to the engine, fuel and hydraulic oil systems no less frequently than at the completion of each work shift.

FIRE PREVENTION

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

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

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

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

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

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.

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.

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

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 15 METERS (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.

Safety

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

EQUIPMENT FIRES ADVERSELY EFFECT YOUR ABILITY TO LOG, MAY INCREASE YOUR INSURANCE PREMIUMS DRAMATICALLY OR PREVENT YOU FROM OBTAINING INSURANCE COVERAGE AT ALL.

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

WHAT TO DO TO PREPARE FOR A MACHINE FIRE

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

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

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

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

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.

1.23

•

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

•

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

•

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

•

Ensure that you have the proper fire extinguishers on site. Most fires involving mobile forestry equipment will be Class A or B. Dry chemical extinguishers should be rated ABC and pressurized water extinguishers should be rated A. 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.

Safety

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

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

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

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

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

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

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

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

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

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

Rinse thoroughly with water. Blow-dry to remove all residual water.

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

1.26

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.

Controls and operation 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.

15. FAN CONTROL This is a rotary, four position switch (0/1/2/3).

When the switch is in the 0 position the cab air fan is OFF. When the switch is in the 1, 2 or 3 position the fan is activated at one of three fan speeds.

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 AUTOMATIC position for optimal cooling.

The FULL ON position is intended for use in the event of a temporary failure of the control system.

16. FAN CONTROL - SWITCH (IF EQUIPPED - VARIABLE PITCH FAN) This is a three position switch, labeled / / (FULL ON/ AUTOMATIC/ CLEAN).

This switch controls the operation of the optional Flexxaire® cooling fan.

The Flexxaire® cooling fan blade pitch is hydraulically varied to control the flow and direction of air through the cooling assembly

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 that there are no personnel standing directly to the sides of the machine when performing this operation, as dust and debris will fly out.

AUTOMATIC Position - AUTOMATIC is the normal operating position for the fan control switch. When the switch is in the AUTOMATIC 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.

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

Automatic control of fan air flow to match your 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 cooling assembly and air conditioning systems. In low temperature operating conditions fan air flow is reduced, as less cooling is required for efficient operation of the cooling assembly.

The auto clean cycle is adjustable through the computer control system menu (ADJUSTMENT MENU ~ FAN SETTINGS).

Refer also to COMPUTER ~ ADJUSTMENT MENU - FAN SETTINGS in THIS SECTION. It is also important to manually clean debris from the machine on a regular basis to maintain low machine operating temperatures.

Refer to CLEANING A/C CONDENSER AND COOLING ASSEMBLY in THIS SECTION.

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

STOPPING ENGINE:

RESTARTING AN ENGINE THAT HAS RUN OUT OF FUEL

CAUTION 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.

1. Park machine on level ground and lower grapple and dozer blade to the ground.

2. Reduce engine speed to LOW IDLE and let run for approximately three to 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.

If the engine runs out of fuel, the fuel line is self priming.

1. Refill fuel tank completely.

2. Turn ignition key to RUN position and observe computer display.

3. Wait for WAIT TO START warning on computer display to turn off.

4. Turn ignition switch to the START position to crank engine.

If it fails to start after 20 seconds, stop and wait for 2 minutes before trying again.

5. When engine starts, release ignition key to RUN position and observe the computer display.

3. Do not race engine before shut-off.

Controls and operation

TRAVELLING WITHOUT A LOAD: Raise the grapple and place the dozer blade in the UP position.

(1) Disengage parking brake. NOTE: Machine will not move if the parking brake is not fully off.

(2) Check the position of the maximum speed control to ensure that it is set to the desired position.

Using the maximum speed control the operator is able to set the maximum travel speed of the machine. This allows the operator to maintain any desired travel speed with full drive pedal operation. Machine travel speed reduction can still be achieved by not fully depressing the foot pedal.

This control can be used while the machine is in motion.

Caution: Setting the maximum speed control to the minimum setting lowers maximum travel speed only, it will NOT prevent the machine from travelling when the forward or reverse travel controls are used.

Refer to STEERING in THIS SECTION for more detailed steering control information.

(5) Use differential locks sparingly and ONLY when additional traction is required.

Never continuously drive the machine with the differential locks on. Serious damage to the axles can result from using the differential locks when they are not needed for additional traction.

NOTE: This machine is equipped with a 10 minute AUTO-OFF feature which automatically deactivates the differential locks after 10 minutes have passed.

NOTE: The high idle adjust function is available.

This function is intended to allow the automatic reduction of the engine high idle speed limit when travelling without a load. Refer also to COMPUTER ~ ADJUSTMENT MENU - ENGINE SETTINGS ~ ENGINE HIGH IDLE ADJUST in THIS SECTION.

(3) ROTATING SEAT & JOYSTICK STEERING

Use the direction selection switch on the left hand joystick to choose forward or reverse and press the travel foot pedal to move the machine in that direction.

STATIONARY SEAT & STEERING WHEEL

Operate the drive travel pedals to move the machine forward or reverse.

(4) Be aware of the type of steering control (and steer valve option - if applicable) the machine is equipped with. Steering control operation varies with the type of controls in use.

Generally, this machine is equipped with Load Sensing Steering. The speed that the vehicle responds to steering control input will vary, depending on the speed that the steering control is moved.

When operating on the road, a slow movement of the steering control will not overcorrect and will steer a straight normal course.

Operating in the woods requires quick steering changes and this is produced by a rapid movement of the steering control, which will quickly change the vehicles direction.

GRAPPLE SKIDDING

CABLE SKIDDING:

1. The timber may be pre-bunched or left for single pick-up. Depending on sizes you may have to single skid or bunch before skidding.

1. Locate the skidder so that the winch cable will lay in a fairly straight line.

2. Lower the dozer and grapple to the ground to anchor the machine.

2. Logs should be picked up 3 ft. (1 meter) from the butt end.

Grapple may have to be raised, depending on winching angle and land terrain.

3. If you have to add more logs or bunch, place the butt end of the new logs crosswise on top of the load in an “X” pattern. Place the Grapple over the logs where they cross and pick up the complete load.

3. Chokers should be attached close to the butt end of the log.

4. The articulation feature in the Skidder increases the reach to the left and right and increases the range of pick-up for the grapple.

5. When pushing or backing up with a load, you must have the logs lined up with the Skidder and backup in a straight line, since you are using the butt pan to push the logs.

4. If skidding multiple logs, attach furthest log away, to end of main cable, with closer logs ahead of it.

5. Winch in a straight line to prevent tip over problems. Note that cab doors must be closed and parking brake disengaged to operate the winch in function.

6. Draw the logs in as close as possible to the butt pan and as high as stability will permit.

WARNING

7. Raise the grapple to a safe height and raise the dozer to its full height.

Backup carefully. If a log strikes an object, it could be pushed forward through the grapple and into the operator's cab.

When running empty, always keep grapple tongs closed to prevent striking the tires or the machine.

8. If you encounter soft ground or steep hills it may be necessary to drop the load “on the move” and allow the winch to “free spool” without stopping the skidder. Once on solid ground or on top of the hill, stop the skidder, lower the dozer and winch the load back into the butt pan.

6. The articulation feature allows decking the logs from both sides of the pile.

9. Adjust your speed to the terrain, ground conditions and the load your skidding.

7. Timber can be piled using the grapple or the dozer blade, depending on conditions.

8. The Dual Arch Skidder has the added ability to reach below ground level. This feature can be used to get the machine unstuck.

Do not drop the load as it helps to support the weight of the machine. Pull the load up close to the butt pan and lower the grapple downwards to solid ground. This process will push the back end of the Skidder upward and forward. Continue to repeat this process until the Skidder is on solid ground.

CARE OF THE MACHINE

INSPECTION AND MAINTENANCE

1. Ensure that all fluid levels are always at the proper level. Use the preventative maintenance schedule in SECTION 3 of this manual .

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

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

•

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.

3. Apply grease to all lubrication points at required intervals.

4. Do not apply load to a cold engine.

5. Close and secure all doors and access covers.

6. Do not allow branches, twigs, leaves or pine needles to build up around radiator intake doors or anywhere else on the machine.

Clean frequently but at least once daily.

Refer to CLEANING A/C CONDENSER AND COOLING ASSEMBLY in THIS SECTION. 7. Be sure that the grapple and dozer blade are resting on the ground before servicing or parking the machine.

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.

Tigercat 615C Skidder

Controls and operation

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 ammonia anti-freeze benzene brake fluid carbon tetrachloride cutting oils gasoline lacquer thinner toluene turpentine xylene

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

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

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

CAUTIONS

FIRE PRECAUTIONS

•

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.

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.

•

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.

•

WINDOW SCREEN HANDKNOB

173-25

SIDE WINDOW SCREENS

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 side window screens can be removed to clean the windows. Screens are provided for the personal protection of the operator and must be reinstalled immediately after cleaning the windows.

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: • • •

SIDE WINDOW SCREEN

Johnson’s Paste Wax Novus Plastic Polish #1 and #2 Mirror Glaze Plastic Polish

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

All handles should be hand tight only at all times.

Be certain to clean the polycarbonate window as outlined prior to application of an automotive polish. Refer to CLEANING INSTRUCTIONS. GRAFFITI REMOVAL •

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

•

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

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

TOWING INSTRUCTIONS (EHS TRANSMISSION) A malfunction of the machines 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.

Prior to towing, be sure that the machine is either on level ground, or is secured by the tow vehicle to prevent the machine from rolling unexpectedly.

IMPORTANT! Before towing, the transmission must always be disconnected from the drive wheels.

615C-025

FRONT DRIVE SHAFT

615C-024

MID DRIVE SHAFT

615C-023

MID DRIVE SHAFT

Never tow a machine in gear. If the machine is subjected to hard pulling while in gear, the extremely high forces created will cause significant damage to the components of the hydrostatic drive system and the transmission Never tow the machine at over 2 mph.

1. To facilitate towing, the drive shafts must be disconnected from the transmission.

2. Disconnect the front drive shaft at the front axle.

3. Remove the mid drive shaft.

4. Raise the grapple and dozer blade off the ground and turn off the engine.

5. To allow the machine to steer while towing and prevent damage to the steering cylinders, cross hydraulic hoses on one of the steering cylinders. This will allow trapped oil to flow freely between the two steering cylinders, providing ease of turning with some dampening effect.

6. The machine will be towed from the front, making use of the towing lugs at front of machine behind the dozer blade.

STEERING CYLINDERS

Ensure a vehicle of equal power and size is used for towing.

STEERING CYLINDERS

When going downhill, be sure to use a holdback vehicle as the machine is now without any effective braking.

7. When towing is completed, reinstall the mid drive shaft, reconnect the front driveshaft and reconnect the steering cylinder hoses in their proper locations.

615C Model

First Sample Follow-up Samples 125 Hours Every 1000 Hours or 6 Months 125 Hours Every Oil Change (500 Hours or 3 Months) 125 Hours Every Oil Change (1000 Hours or 6 Months)

Effective for all 2007 model year 600 'C' and 'D' series skidders sold in North America, fluid sampling must be performed during the warranty period as per the schedule below.

Warranty coverage of powertrain components, specifically hydrostatic pumps and motors, auxilliary pumps, axles, transfer case and driveshafts is contingent on performance of regular fluid sampling at the owner’s expense during the warranty period.

FIRST SAMPLE There will be no charge for the first fluid samples required to be taken during the 125-Hour Inspection Service that will be scheduled and performed by your Tigercat dealer. Refer to NEW MACHINE MAINTENANCE in THIS SECTION. FOLLOW-UP SAMPLES All follow-up samples must be taken as indicated in the chart above and will be the responsibility of the machine owner.

Copies of all fluid analysis results must be forwarded to the Tigercat Warranty Department for continued warranty coverage. If samples are taken using the Tigercat Fluid Analysis Program, a copy of all results will automatically be sent to Tigercat.

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 followup fluid samples.

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

TIGERCAT FLUID ANALYSIS KITS Each kit includes a Pre-paid Sample Bottle and Sample Information Form. Pre-printed mailing labels are also included to ensure all samples are quickly returned directly to the lab for immediate analysis and results within 24 hours of receipt.

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

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

Contact your Tigercat Dealer Parts Department to order Kits.

Tigercat 615C Skidder

Lubrication and Maintenance

TIGERCAT FLUID ANALYSIS PROGRAM FLUID SAMPLE COLLECTION PROCEDURES Fill out the Sample Information Form (SIF) completely and accurately. When taking multiple fluid samples, fill out all of the required SIF forms in their entirety, prior to taking any fluid samples.

Then, immediately package each completed SIF form together with the matching fluid sample in the black outer shipping container as each individual sample is taken. This will reduce the possibility of mixing up or incorrectly identifying the SIF forms and fluid samples. Incorrectly identified samples could result in a false warning alarm.

HYDRAULIC SAMPLE VALVE

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 follow-up samples should be consistently taken from the same location using the same techniques as all previous samples.

•

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

•

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

•

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

•

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

615C-013

MAIN HYDRAULIC OIL

Hydraulic Oil Samples:

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

3.5

•

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

•

To obtain a representative oil sample, sample valves must be purged before the actual oil sample is taken. Drain a minimum of 3 or 4 ounces of oil into a separate container and discard this oil using approved recycling methods.

•

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

Tigercat 615C Skidder

Lubrication and Maintenance

TIGERCAT FLUID ANALYSIS PROGRAM Transmission and Axle Oil Samples: •

These samples can be taken during the oil change process.

•

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

•

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

•

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

GENERAL 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.

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

Clean around filler caps before checking or adding fluids Release hydraulic pressures and 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. Should any exhaust leaks occur during operation, the machine must be shut down immediately and not put back to work until the necessary repairs have been completed.

Clean 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

Top up diesel fuel AT END OF Each shift to reduce contamination by condensation

For safety; when leaving the cab or leaving machine unattended or during service, always lower grapple and dozer blade to the ground

Clean up oil spills on walking surfaces and top of engine enclosure immediately

For safety, always block or support grapple and dozer blade when working under them.

Before welding on machine be sure master switch is disconnected

CHECK EMERGENCY EXITS MONTHLY~

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

Alternate exit routes are provided: the sliding windows in the cab doors. These are only to be used if the cab doors cannot be opened.

Clean away all branches, bark and chips.

Clean up all traces of oil to avoid fires

It is therefore essential that these emergency exits be checked at least once per month to ensure they are fully operational.

GENERAL 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.

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.

2. Pay close attention to wiring and plumbing routings during maintenance, ensure that ALL wiring harnesses or hydraulic hoses are properly restrained and clamped to prevent damage from chaffing.

3. Read the fire suppression system manual and have the system serviced regularly by qualified personnel.

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

Also refer to the SAFETY section of this manual for additional information on how to prevent fires from starting on the machine.

HYDRAULIC OIL DOUBLE ELEMENT FILTERS

DOUBLE ELEMENT FILTER

HYDRAULIC FILTER SERVICING GUIDELINES NEVER PRE-FILL HYDRAULIC FILTERS

BREATHER BLUE ELEMENT

Tigercat does not recommend the pre-filling of spin-on filters due to the risk of damage to the hydraulic system caused by unfiltered oil. Unfiltered oil used to pre-fill filters enters directly into the hydraulic circuit.

Contaminants in unfiltered oil can cause significant and costly damage to hydraulic valves, pumps and motors. The cleanliness of hydraulic oil cannot be guaranteed unless it is always prefiltered before use.

HYDRAULIC TANK, FILTERS AND SIGHT GAUGE

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

The hydraulic oil cooling circuit contains a double filter head with a built in 25 psi (1.7 Bar) bypass valve. In the event of a clogged filter element or thicker oil on cold starts, this bypass filter will open and redirect oil around the filter element. It is recommended that all machines use two different filter elements: 1 white, Tigercat high performance, full flow hydraulic oil filter element 1 blue, Tigercat water absorbing, full flow hydraulic oil filter element.

Refer to SCHEDULED MAINTENANCE and SERVICE AND LUBRICATION AND SERVICE POINTS in THIS SECTION. 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 SECTION 3 of THIS MANUAL. Use of hydraulic filters other than the Tigercat brand could lead to severe wear and rapid failure of hydraulic system components.

3.21

•

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

1. When suspended the dozer blade, grapple, and arch/boom will tend to extend the hydraulic cylinders supporting them due to gravity.

2. Remove the function valve cover in the rear chassis.

WARNING Use caution when working on top of the rear chassis, as there are many pinch areas between the arch, arch cylinders and winch (if equipped). DO NOT move arch when workers are in this area.

Use caution and follow all safety warnings when working in this area. Never stand under an object supported with hydraulics. Always use safety stands or a locking device.

Do not work under the arch without properly supporting the arch/grapple assembly.

NEVER move the arch/grapple assembly when workers are in this area.

3. Refer to the label in the valve compartment or this manual to locate valve section for the element you wish to lower. Locate the spool limiting set screw at the end of the spool section of interest.

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

4. Use a wrench to loosen the jam nut that secures the spool limiting set screw. Use an allen wrench to slowly turn the set screw clockwise (IN). Continue until the set screw starts to contact the spool inside the valve.

Movement of booms and cylinders could result in death or serious injury.

DO NOT perform work on valves or piping until boom and attachment are lowered to the ground and engine is shut off.

5. At this point the spool will allow pressurized oil on the rod side of the cylinder to travel to the valve tank port and thus lower the implement.

6. Repeat steps 3 to 5 for all raised implements.

7. Restore spool limiting set screws to their factory setting and secure jam nuts prior to operating the machine.

SERVICE BRAKE CHECKING BRAKE AND ACCUMULATOR FOR PROPER OPERATION

Service Brake

The main pump supplies oil directly to the brake accumulator, via a check valve inside the main pump block to charge the accumulator to specified pressure. The accumulator is installed to ensure that the brake control remains responsive at all times by maintaining an optimum pilot pressure of 3000psi to the brake pilot valve. This oil from the accumulator side of the check valve is sent to the brake foot control valve.

Pressure Low. Service machine to correct.

8. If the Service Brake Pressure Low warning appears on the screen before the brake has been pumped 5 times from a full charge investigate the cause.

The accumulator when functioning properly will hold sufficient pressure for up to 5 brake applications after the engine stalls or is turned off, beyond this the pressure drops substantially.

Check first for leaks in the brake circuit. If no leaks are found check for proper operation of the brake pedal valve, accumulator, check valve and brake pressure sensor.

For more information about the service brake circuit refer to SECTION 9 of THE SERVICE MANUAL.

For more information about the service brake circuit refer to SECTION 9 of THE SERVICE MANUAL.

PROCEDURE: 1. Park machine on level ground, lower dozer and grapple to the ground, stop engine and engage parking brake and block wheels.

2. Release the pressure stored in the brake accumulator by fully applying the brake foot pedal repeatedly until there is no pedal resistance. This may take a minimum of 150 applications.

3. Start engine.

NOTE: The engine will not turn over unless the parking brake is ENGAGED. 4. Disengage parking brake to fully charge the accumulator. Run engine for 10 seconds, then shut engine off.

NOTE: When the parking brake is DISENGAGED full pressure is available from the main pump to the brake accumulator.

5. Engage the parking brake.

6. Fully apply the brake pedal 5 times. The accumulator pressure should remain above 800 psi (no warning on the computer display).

As the pressure drops in the accumulator the brake pedal will become spongy.

Once the pressure falls below 800 psi the Service Brake Pressure Low warning will appear on the screen.

630C-19

CENTRI® PRECLEANER OPERATION

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

OPERATION: 1. Air enters the precleaner.

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

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

4. Contaminants are blown out the discharge louver.

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

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

Continued on next page

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

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

FILTER RESTRICTION INDICATOR

This valve should be replaced every 1000 hours.

Remove the unloader valve from the tube of the air cleaner housing. Check and clean the valve.

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

ENGINE AIR PRECLEANER

AIR CLEANER 604C-206

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 valve should suck closed at 1/3 throttle.

FILTER RESTRICTION SWITCH

ENGINE AIR CLEANER

AIR CLEANER The air cleaner on this machine uses two filter elements, a primary element and a safety element accessible from the right side of the engine compartment.

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

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

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

FILTER RESTRICTION INDICATOR

A filter restriction indicator is mounted to the output side of the filter, this should show green when the engine is running under load. Service is required if the indicator shows red. The filter restriction indicator is equipped with a switch used to send a signal to the computer control system in the event of a filter restriction.

Engine Air Intake Filter Restricted. Service Machine to correct.

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

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 at the beginning of every shift. (8 hours). Repair or replace defective parts 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.

When a signal is received from the restriction indicator switch on the engine air cleaner a warning message will be displayed. Refer to COMPUTER~MESSAGES- ALERT~ENGINE AIR INTAKE FILTER RESTRICTED in SECTION 2 of the OPERATOR'S MANUAL.

OVER SERVICING

OUTLET TUBE

Filter elements increase in dust cleaning efficiency as dust builds up on the media. Looks can be deceiving. A filter that looks 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 engine manufacturer's guidelines, should a filter be replaced.

PRIMARY ELEMENT

NOTE: This does not apply to oil filters.

SAFETY ELEMENT

IMPROPER SERVICING Engine exposure to dust during servicing is the largest single reason for engine damage due to dust.

Abrasive dust can easily enter the intake system once the air cleaner cover and protective filter element is removed for replacement. The safety element does reduce this risk but it should also be replaced at every third primary element change.

AIRCLEANER

AIR FILTER ELEMENTS

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

2. Avoid dislodging dust from filter element(s) by gently pulling the element off the outlet tube.

3. Always clean the sealing surface of the outlet tube before inserting a new filter element.

4. Always clean the inside of the outlet tube and filter housing.

5. Check your old filter, It can help you detect foreign material on the sealing surface that is causing leakage.

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

6. Inspect the new filter for damage.

7. Insert the new filter properly. Apply pressure to the outer rim of the filter not the flexible centre.

8. Inspect connections and ducts for air tight fit.

Ensure that all clamps, bolts and connections are tight. Check rubber elbows for splits or wear points and replace as needed. Leaks in these locations send dust directly to the engine.

GRAPPLE SNUBBER MAINTENANCE SNUBBER ASSEMBLY USED ON TIGERCAT GRAPPLES In this model the snubbers are part of the link.

Two separate snubbers provide snubbing action in two directions. There is a grease fitting on each snubber assembly for daily lubrication. Be sure to lubricate all the grapple snubbers on your machine.

Proper lubrication prevents excessive clutch wear.

IMPORTANT !

All service points on snubbers must be greased every shift (8 hours) to ensure a long service life.

ADJUSTING SNUBBER TENSION Each snubber should be adjusted such that: •

•

It is capable of stopping the grapple within one full swing.

615C-022

SNUBBER ASSEMBLY

Snubbers that are too loose can allow the grapple to swing violently and cause damage to the grapple and/or other machine components.

PROCEDURE

It is capable of holding the grapple at approximately a 5° angle.

1. Park machine on level ground, install articulation lock bar, lower dozer and grapple to ground, stop engine, engage parking brake and block wheels.

Snubbers that are overtightened can reduce the effect of lubricating grease and cause premature clutch wear.

Tension is adjusted by removing shims from the snubber. Remove only the minimum number of shims required to achieve correct adjustment.

2. Remove one shim at a time to increase snubber friction. One split shim at a time can be removed from each snubber without completely removing the end caps.

Remove 3 bolts on the left side then loosen 3 bolts on the right side of the snubber enough to separate the end cap from the housing to remove the first half of the shim.

Loosely reinstall the 3 bolts on the left side of the snubber then remove the 3 bolts on the right side keeping the end cap separated from the housing enough to remove the other half of the shim.

Reinstall bolts and tighten in a crisscross pattern.

3. Fill snubber with grease until grease comes out the exhaust port.

STARTUP PROCEDURE AFTER MAJOR MACHINE MAINTENANCE

•

Prepare the hand fill pump on the machine to add hydraulic oil. Clean the fill line pipe, remove cap on end of pipe and insert pipe into oil supply drum.

•

Loosen the plug on the top of the left hand drive motor.

•

Operate the hand fill pump at medium speed, using a steady motion.

•

Watch for oil leaking from the plug previously loosened and tighten plug when oil leaks out.

•

Continue pumping slowly and watch the oil sight gauge on the reservoir. Continue pumping slowly until the hydraulic tank is full.

This procedure should be followed: •

after major service or a rebuild.

•

whenever the machine has been drained of hydraulic oil.

•

when any major component has been removed, repaired or replaced.

PRE-STARTUP AND FILLING 1. Ensure all filters are in place. Refer to FILTERS in THIS SECTION. 2. Check oil levels in the engine, transmission, main hydraulic tank, winch (if equipped), axles and cab tilt system.

MACHINE STARTUP Before beginning this procedure, perform the PRE-STARTUP AND FILLING steps.

3. Check coolant level in the radiator.

4. Do a final inspection of all fittings and clamps to make sure they are tight and will not leak.

CAUTION Machine operator must ONLY take directions from the person doing the set-up.

5. Install the articulation lock bar and engage the parking brake.

6. Turn differential lock switch to OFF.

1. Ensure the articulation lock bar is installed.

7. Do not start engine. Purge air from hydraulic system by adding oil as follows: •

Pre-fill the cases of the hydrostatic drive pump, main pump and any other components that have been drained of oil with clean, filtered hydraulic oil.

•

Disconnect the case drain make-up line from the tee connection on the right hand drive motor and pre-fill the right hand drive motor with clean, filtered hydraulic oil.

•

Watch for oil leaking from tee connection and reconnect case drain line when oil leaks out.

3. Crank engine for 10 seconds, wait for 10 seconds. Repeat 6 times to pump oil into pumps.

4. Check hydraulic oil levels in the main hydraulic tank and add hydraulic oil as required.

3.50

Tigercat 615C Skidder

Lubrication and Maintenance

5. Reconnect 4 pin engine power connector on engine.

6. Start engine.

7. Check for leaks.

12. With cylinders fully retracted, top up the main hydraulic oil reservoir with clean hydraulic oil.

NOTE: If the machine was on wheels, the steer and drive functions were not properly purged or flushed. Remove the articulation lock bar and at LOW IDLE, slowly operate the steer function right and left a few times. With the parking brake disengaged and at LOW IDLE, slowly operate the drive function forward and reverse a few times.

DRIVE PUMP

NOTE: If possible, allow the machine to stand for 4 to 6 hours before setting any of the operating pressures. This will allow any air bubbles in the oil to escape and is a good time to check for leaks.

CONNECTORS

604C-221

11. Top up the radiator with clean coolant.

DISCONNECT TWO CONNECTORS ON DRIVE PUMP PRIOR TO BLEEDING BRAKES

8. Bleed brakes (front axle) if required.

Prior to bleeding brakes disconnect the two connectors on the drive pump. This is a safety precaution to prevent the machine from travelling while brake bleeding is being performed.

With engine at IDLE, parking brake engaged, hold foot brake down, bleed brakes in front axle (both sides). Refer also to FRONT AXLES ~ SERVICE BRAKES ~ BRAKE BLEEDING in SECTION 8 of the SERVICE MANUAL. Reconnect two connectors on drive pump.

9. Set throttle to IDLE and run each function for 2 minutes to purge air from circuit.

10. Set throttle to FULL and run each function again for 2 minutes to flush circuit.

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

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

• Four bolts and washer

WASHERS BOLTS FLANGE CLAMP

Flange Port Assembly

FLANGE HEAD

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

2. Lubricate the O-ring.

3. Position flange and clamp halves.

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

5. Hand tighten bolts.

6. Torque bolts in diagonal sequence (see Fig. T9) in small increments to the appropriate torque level listed in Table T6 or Table T7 on this page.
