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.

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

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

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

• Seek professional medical attention immediately.

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

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

Always wear thick protective gloves.

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

FIRE PREVENTION

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

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

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

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

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

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

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

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

1. Maintain a CHARGED fire extinguisher on the machine at all times and KNOW HOW TO USE IT. 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 AND COOLING ASSEMBLY 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.

1.17

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.

Tigercat E620C Skidder

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

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.

1.18

•

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.

WHAT TO DO WHEN A MACHINE FIRE OCCURS •

If operating the machine when a fire occurs: 1. Lower all working attachments to the ground.

Ensure that your fire detection system* is in working order. Refer to FIRE DETECTION SYSTEM in SECTION 2 of the OPERATOR’S MANUAL.

2. Shut the engine off.

3. Activate the fire suppression system**.

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

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.

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

Ensure that you are familiar with the recommended procedures for fire contained in the emergency action plan of your company.

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

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:

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

•

Before deciding to fight the fire, be certain that:

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

1. The fire is small and not rapidly spreading.

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

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

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

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

•

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.

•

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.

•

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

Ensure that after you have received the training as outlined above, that you know how to use the fire extinguisher, the pressurized water system (if applicable) and the fire suppression system** on your machine.

There is not enough time available to read instructions during a fire emergency.

Safety 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.

FIRE PREVENTION continued DRY CHEMICAL CLEANUP PROCEDURES

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

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

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

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

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

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

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

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

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

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

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

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

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

Controls and operation QUICK STEER VALVE (OPTIONAL) This machine is equipped with Variable Ratio Load Sensing Steering. The speed that the vehicle responds to the steering wheel input will vary; depending on the angle the steering wheel is turned. Turning the steering wheel ±50° results in controlled flow, from zero to full steering flow.

When operating on the road, turning the steering wheel only a few degrees in either direction will result in slower steering, not overcorrect and will steer a straight normal course.

•

Operating in the woods requires quick steering changes and this is produced by fully turning the steering wheel (± 50°), which will fully lock steering and quickly change the vehicle’s direction.

METERED STEER VALVE This machine is equipped with Variable Ratio Load Sensing Steering. The speed that the vehicle responds to the steering wheel input will vary, depending on the speed at which the steering wheel is moved.

The horn button is located in the center of the steering wheel.

When operating on the road, a slow movement of the steering wheel 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 wheel, which will quickly change the vehicle's direction.

PUSH down on the handle to DISENGAGE parking brake.

This parking brake operates a disc brake calliper on the transmission.

NOTE: The parking brake must be in the ENGAGED position to START the engine, and in the DISENGAGED position to DRIVE the machine.

E620C-08

PARKING BRAKE ~ ENGAGED POSITION

The drive prevent logic circuit prevents the machine from being driven when the parking brake is ON. A limit switch is attached to the brake lever housing. When the brake lever is in the ON position the limit switch is activated. When the brake lever is in the fully OFF position the limit switch is de-activated. The signal is sent to the computer control system.

Keep the brake properly adjusted at all times.

The parking brake linkage must be kept properly adjusted at all times and should be serviced (adjusted and lubricated) every 500 hours during normal operating conditions.

Refer to PARKING BRAKE ADJUSTMENT in SECTION 9 of the SERVICE MANUAL.

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

7. DOZER BLADE CONTROL LEVER

Caution: Turning the maximum speed control dial completely to the left (minimum setting) lowers maximum travel speed only, it will NOT prevent the machine from travelling when the forward or reverse travel pedals are used.

Pull the lever BACK to RAISE the dozer blade.

Push the lever FORWARD to LOWER the blade.

10. FAN CONTROL - SWITCH (IF EQUIPPED WITH OPTIONAL FLEXXAIRE® FAN)

The control lever will return to the center neutral position when the handle is released.

NOTE: Always travel with the dozer blade in the raised position to avoid obstacles.

This is a three position switch, labelled FULL ON / AUTOMATIC / CLEAN. This switch controls the operation of the optional Flexxaire® cooling fan.

CAUTION

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

Never use the dozer blade to remove tree stumps or large boulders.

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 IQAN computer system automatically adjusts fan air flow to the minimum required level to maintain optimal operating conditions.

WARNING When leaving the cab, always lower the grapple and dozer to the ground, engage the parking brake and turn the ignition switch off.

If leaving the Skidder unattended, also remove the ignition key and switch the battery disconnect switch to “off”.

8. WINCH CONTROL LEVER Press activation switch on top of lever and pull and hold the lever BACK to wind in the winch cable.

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 control lever will return to the center neutral position when the handle is released.

The neutral or center position actuates the winch pinion brake and prevents the drum from rotating.

Operating the WINCH FREE SPOOL switch (on control panel) permits the cable to unwind freely. The cable can then be pulled from the drum by the operator. Refer also to WINCH FREESPOOL SWITCH and OPERATING WINCH in THIS SECTION. 2.18

The auto clean cycle is adjustable through the IQAN control system menu (PROPERTIES~ OTHER~FUNCTION PARAMETERS). Refer also to COMPUTER ~INFORMATION CENTER ~ SYSTEM DIAGNOSTICS MENUS ~ DIAGNOSTICS MENU OPERATION ~ PROPERTIES MENU 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. 11. WINCH FREESPOOL - SWITCH

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

This is a two position switch. Place this (freespool) position to switch in the disconnect the drive motor from the drum in the winch and allow the cable to be freely pulled from the spool. Free spool must be turned off to activate a pull with the winch.

Note: An alarm warning light will flash, "Winch freespool on" will appear on the IQAN-MDM computer display, and alarm will sound whenever the winch control switch is in the FREE SPOOL position.

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.

12. ENGINE IDLE SPEED This is a three position momentary switch which spring returns to the center neutral position when released.

To increase engine idle RPM press and hold the switch in the position, release switch to the center neutral position when the desired engine speed is reached.

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.

To decrease engine idle RPM press and hold the switch in the position, release when the desired engine speed is reached.

For recommended engine rpm values, refer to COMPUTER ~INFORMATION CENTER ~ GAUGE MENUS ~ ENGINE SPEED in THIS SECTION.

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

The auto clean cycle is adjustable through the IQAN control system menu (PROPERTIES~ OTHER~FUNCTION

SYSTEM TEST AND WARM-UP

(k) Engage the parking brake.

Before commencing skidding operations, follow steps (a) thru (m) to accomplish the following:

(l) Decrease engine idle speed to LOW IDLE.

• Warm up the hydraulic system.

CAUTION

• Test all systems for proper operation.

• Inspect for hydraulic oil leaks.

Ensure that the machine was parked on level ground at last shutdown: (a) Start engine.

Never use your bare hand to check for fluid leaks.

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

(b) Ensure gauges (IQAN-MDM displays) and warning lights are indicating normal operating conditions. (c) Check that all personnel are clear of the machine. (d) Slowly raise and lower the arch, check for proper operation.

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

With the grapple and dozer raised slightly off the ground: (e) Operate the grapple arms and check for proper operation. (f) Rotate grapple in each direction for several revolutions and check that it is operating correctly. (g) Raise and lower dozer blade (h) Steer the machine to the left and right. (i) When cold weather conditions exist, continue the process of warming up the hydraulic system by repeating steps (d) "thru" (h) several times. As the hydraulic system warms up, engine speed can be increased gradually to the HIGH IDLE. (j) Observe all operations. If any operations are not functioning as they should, take the necessary steps to correct the problem.

After completion of the warm-up and system testing, lower the dozer blade and grapple to the ground.

STOPPING ENGINE:

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

CAUTION

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

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.

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

Using the maximum speed control dial 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.

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.

Turn the dial to the right to increase maximum travel speed. Turn the dial to the left to decrease maximum travel speed of the machine. This control can be used while the machine is in motion.

3. Do not race engine before shut-off.

4. Parking brake ON. 5. Stop engine by turning ignition switch to the OFF position.

Caution: Turning the maximum speed control dial completely to the left (minimum setting) lowers maximum travel speed only, it will NOT prevent the machine from travelling when the forward or reverse travel pedals are used.

WARNING Before leaving the machine, park it in a safe position on level ground. Engage parking brake and lower the grapple and dozer blade to the ground.

Never work behind, in front of, or below a skidder that has been parked on a grade.

Take additional precautions by placing the wheels against a rock, tree or other secure object.

(3) Operate the drive foot pedals to move the machine forward or reverse.

(4) This machine is equipped with Variable Ratio Load Sensing Steering. The speed that the vehicle responds to the steering wheel input will vary, depending on the speed that the steering wheel is moved. When operating on the road, a slow movement of the steering wheel 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 wheel, which will quickly change the vehicles direction.

WARNING When leaving the cab, always lower the dozer blade to the ground, engage the parking brake and turn the ignition switch OFF. If leaving the Skidder unattended, also remove the ignition key and switch the battery disconnect switch to OFF.

(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.

CONTROL PANEL 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.

CONTROL PANEL 1. LIGHTS FRONT - SWITCH This switch turns on working lights.

2. LIGHTS REAR - SWITCH This switch turns on working lights.

3. AUX (OPTIONAL) Applicable to optional light packages.

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.

4. AUX (OPTIONAL) Applicable to optional light packages.

5. 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.

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

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

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

Controls and operation

Refer also to COMPUTER ~ ADJUSTMENT MENU - FAN SETTINGS in THIS SECTION.

6. PARKING BRAKE SWITCH

P

This is a three position switch which operates a driveline brake.

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

Momentarily press the top of this switch (ON) to ENGAGE the parking brake. The parking brake icon on the main menu of the computer display will be illuminated when the parking brake is engaged. The switch will spring return to the center position.

Momentarily press the bottom of this switch (OFF) to DISENGAGE the parking brake. The switch will spring return to the center position.

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.

NOTE: The parking brake must be ENGAGED to START the engine, and DISENGAGED to DRIVE the machine.

NOTE ALSO: The interlock system prevents the machine from being driven and function controls from being operated while the parking brake is ENGAGED. As part of the interlock system this machine automatically engages the parking brake whenever a cab door is open. This prevents accidental or improper operation of the controls from anywhere but the operator's seat.

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.

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

Controls and operation (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.

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

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

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.

(3) Operate the drive foot 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.

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

Controls and operation

GRAPPLE 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.

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

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.

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.

WARNING 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.

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

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.

2.156

Tigercat E620C Skidder

Controls and operation

CABLE 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. Engage parking brake.

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

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

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.

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

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

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, engage the parking brake and winch the load back into the butt pan.

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

CARE OF THE MACHINE

CARE OF POLYCARBONATE WINDOWS IN CAB

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

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.

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

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.

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.

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.

2.158

Controls and operation

INSPECTION AND MAINTENANCE

RESISTANCE TO CHEMICALS

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

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.

•

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.

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 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.

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. 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.

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

Tigercat E620C Skidder USING THE FAN CLEAN FUNCTION TO REMOVE DEBRIS DURING OPERATION (IF EQUIPPED-VARIABLE PITCH FAN OPTION) The Flexxaire® cooling fan has a CLEAN function for use in cleaning debris from the machines engine enclosure. 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 machine's 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.

When the fan control switch is in the AUTOMATIC position, the system will automatically cycle through an auto clean cycle. The frequency and duration of the auto clean cycle is adjustable through the computer control system menu.

Refer to FAN CONTROL SWITCH in THIS SECTION for more information.

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

E620C Model Location First Sample Follow-up Samples Hydraulic Oil 100 Hours Every 1000 Hours or 6 Months Transmission 100 Hours Every Oil Change (500 Hours or 3 Months) Axles – Front & Rear 100 Hours Every Oil Change (1000 Hours or 6 Months)

FIRST SAMPLE There will be no charge for the first oil samples required to be taken during the 100-Hour Inspection Service that will be scheduled and performed by your Tigercat dealer. Refer to NEW MACHINE MAINTENANCE in THIS SECTION. FOLLOW-UP SAMPLES All follow-up samples must be taken as indicated in the chart above and will be the responsibility of the machine owner.

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

Tigercat Oil Analysis Kits are available from your Tigercat dealer parts department. If required, arrangements can also be made with your Tigercat dealer to supply and perform all of the required followup oil samples.

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

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

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

Lubrication and Maintenance

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

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.

•

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.

HYDRAULIC SAMPLE VALVE

•

HYDRAULIC OIL OS MAIN 604 610 620C

Hydraulic Oil Samples: •

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

•

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.

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.

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.

BLUE ELEMENT

•

• HYDRAULIC HAND FILL PUMP

NEVER PRE-FILL HYDRAULIC FILTERS

BREATHER

SIGHT GAUGE

• •

Tigercat generally does not recommend the prefilling 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.

IMPORTANT • CHARGE PRESSURE FILTER

E620C-02

HYDRAULIC TANK, FILTERS AND SIGHT GAUGE

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:

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 OF THIS MANUAL. Use of hydraulic oil filters other than the Tigercat brand could lead to severe wear and rapid failure of hydraulic system components.

WARNING

ENGINE AIR CLEANER

AIR PRECLEANER (IF EQUIPPED) The optional engine air precleaner cleans engine air before it reaches the air cleaner filter elements.

It removes contaminants such as dust, powder, insects, rain and snow. The air precleaner should be checked every 8 hours to make sure that foreign materials have not plugged the intake area or the discharge louver area. Clean as required.

CENTRI® PRECLEANER OPERATION

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.

IMPORTANT The air inlet hood or air precleaner must be check every 8 hours and cleaned as required.

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

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

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

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

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.

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

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. This machine is equipped with a switch used to send a signal to the computer control system in the event of a filter restriction.

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.

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.

When operating in high dust conditions, the unloader 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.

The most common and damaging servicing problems are: OVER SERVICING 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.

NOTE: This does not apply to oil filters.

ENGINE AIR PRECLEANER

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.

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. Check connections and ducts for air tight fit.

Ensure that all clamps, bolts and connections are tight. Check rubber elbows for splits or wear points. Leaks here send dust directly to the engine.

ESCO CRG 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.

625C-12

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

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

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

•

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

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

PROCEDURE Tension is adjusted by removing shims from the snubber.

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

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 one half of the shim.

Reinstall bolts and tighten in a crisscross pattern.

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