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.

GENERAL SAFETY PRECAUTIONS continued

Do not operate the machine with any of the exhaust system, safety covers, or other devices removed.

To reduce the risk of fire, machines should be completely cleaned of debris at least daily, particularly around the engine exhaust components. Hydraulic oil leaks, excess grease, fuel and oil accumulation (including spillage) should be eliminated immediately, always shut off engine before cleaning machine.

Do not operate the machine with the cab retaining pins removed. Always install retaining pins and fasten front guards to cab roof after lowering the cab.

Maintain a clean cab interior, clear away trash or debris.

Machine should be washed completely at every major service.

Inspect the machine daily for signs of damage or unusual wear, to ROPS, FOPS, OPS structures.

Keep a first aid kit in an easily accessible location on the vehicle at all times.

The machine should be inspected daily for signs of fluid leaks, damage, unusual wear, or faulty operation. Repair or replace malfunctioning parts and systems immediately.

Working with oil Direct contact with oil implies a risk of skin complaints (example: eczema). Strict hygiene should always be observed.

Check window and door guards for damage.

Some advice which should be observed:

Check protective windows for cracks, a damaged window has reduced strength to stop flying objects. All damaged windows must be replaced with original equipment.

• • •

Check windows for scratching, crazing and cloudiness that could impair clear visibility all round the machine.

•

Do not operate the machine with any defective or inoperable components.

• • • • • •

Oils used in this machine may be hot enough to cause serious burns.

Avoid contact with oil, particularly heated oil.

Oil on the skin should be washed off immediately with soap and water.

Wear protective gloves. Hands should be clean before putting on gloves. Apply protective cream to the hands to make washing easier.

Don't put oily rags in your pockets.

Oil soiled clothing should be changes as soon as possible.

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

Cuts and abrasions must be attended to immediately. Clean them and apply first-aid.

Avoid breathing in oil fumes.

Wash hands and arms frequently (example: at each meal break or as often as possible).

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.

1.4

Tigercat E625C Skidder GENERAL SAFETY PRECAUTIONS continued 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.

Safety 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 vehicle moving 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. Do not carry passengers either in the cab or anywhere else on the machine. The vehicle seating accommodation is for one operator only.

Be aware when performing service and maintenance tasks that surfaces and grab handles in and around the engine and cooling system may become very hot when the engine has been running. Contact with hot surfaces may cause injury.

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

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

When operating the machine, ensure there is adequate clearance on both sides and above the machine or any of its attachments. Additional clearance may be necessary where the ground is uneven.

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

Extreme caution should be exercised when approaching any area where overhanging electrical powerlines are present. Serious injury or death by electrocution can result if the machine or any of its attachments are not kept a safe distance from these lines.

Safety FLUID INJECTION INJURY

SERVICING SAFETY PRECAUTIONS continued

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.

If the engine is running inside a building, ensure that sufficient ventilation is available to prevent a build-up of toxic exhaust fumes. Run the engine only when it is necessary for testing or adjustments.

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.

Work in a ventilated area. If it is necessary to run an engine in an enclosed area, use an exhaust pipe extension to remove toxic exhaust fumes.

If you don't have an exhaust pipe extension, either work outside, or open the shop doors.

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.

Dispose of fluids properly.

Do not pour fluids into the ground, stream, pond.

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

Before draining any fluids, know the proper way to dispose of them.

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.

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

• Seek professional medical attention immediately.

Safety GREASE INJECTION INJURY WHEN USING PNEUMATIC GREASE GUNS

SERVICING SAFETY PRECAUTIONS continued

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.

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.

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.

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.

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:

•

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.

1.15

•

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, 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.

1.16

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 E625C 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.

1.17

•

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.

FIRE PREVENTION continued •

•

•

•

•

Ensure that the nozzle of any hand held extinguisher and pressurized water system available on the machine and at the work site fits within the access holes in the doors of the machine.

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 WHAT TO DO AFTER A MACHINE FIRE HAS OCCURRED

FIRE PREVENTION continued •

•

1. Ensure that the cause of the fire is determined and all appropriate repairs are completed.

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

•

•

•

•

Before returning the machine to work.

Pull the pin at the top of the extinguisher that keeps the handle from being pressed.

Break the plastic seal as the pin is pulled.

2. Ensure that the fire detection system* or the fire suppression system** is properly serviced and in working order (if applicable).

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

Release the hose before taking aim.

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

•

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

Notify your equipment dealer and / or Tigercat Industries Inc. by completing an incident report, Tigercat form number 5101.

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

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

TYPICAL FIRE EXTINGUISHER ACCESS HOLE

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

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

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

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

Remain with the machine until help arrives.

1.19

Tigercat E625C Skidder

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.

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.

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

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 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. 2.16

Tigercat E625C Skidder

Controls and operation

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

PARAMETERS). Refer also to INFORMATION CENTER ~ SYSTEM DIAGNOSTICS MENUS ~ DIAGNOSTICS MENU OPERATION ~ PROPERTIES MENU in THIS SECTION.

The auto clean cycle is adjustable through the IQAN control system menu (PROPERTIES~ OTHER~FUNCTION PARAMETERS). Refer also to 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 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

CONTROL PANEL

CONTROL PANEL (6250302, 6250324 TO 625330)

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.

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.

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

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

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.

This is a three position switch, labelled 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

PARAMETERS). Refer also to INFORMATION CENTER ~ SYSTEM DIAGNOSTICS MENUS ~ DIAGNOSTICS MENU OPERATION ~ PROPERTIES MENU in THIS SECTION.

The auto clean cycle is adjustable through the IQAN control system menu (PROPERTIES~ OTHER~FUNCTION PARAMETERS). Refer also to 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.

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.

6. NO FUNCTION AT THIS TIME 7. PILOT SYSTEM RESET - SWITCH This is a push ON spring return switch.

This function prevents accidental or improper operation of the controls from anywhere but the operator's seat.

With the engine running, parking brake OFF and the cab doors closed, push this switch to REACTIVATE the pilot system after it has been deactivated by opening a cab door or by turning the key switch to the OFF 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.

WARNING Do not, under any circumstances allow the pilot system to be re-activated without an operator in the cab.

8. HORN, SAFETY ALERT - SWITCH This is a two position "momentary" switch.

Press and hold this switch to sound the safety alert horn.

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.

Always use this horn prior to starting the engine and to alert other personnel in the area of your presence.

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 (e) "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.

2.72

Tigercat E625C Skidder

Controls and operation

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.

Tigercat E625C Skidder

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.

2.78

Tigercat E625C 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 the 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.

(6250301 TO 6250320, 6250324 TO 6250330)

STEERING CYLINDERS

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.

1. To facilitate towing, the transmission must be placed in NEUTRAL, this will disconnect the wheels from the hydraulic motors.

SM47

The transmission disconnect lever is accessed from the right side, between the cab and heat exchanger assembly. A short bar is placed through the hole in the lever and pulled upwards to put the transmission into neutral.

HOSES ON ONE CYLINDER CROSS CONNECTED FOR TOWING

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

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

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

3. 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.

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

5. When towing is completed, reconnect steering cylinder hoses in proper location.

DISCONNECT LEVER

CAUTION Before towing, the transmission must always be placed in NEUTRAL. 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. This will cause significant damage to the transmission.

Never press the forward or reverse pedals while the transmission is in neutral. This will cause significant damage to the transmission.

TIGERCAT OIL SAMPLING PROGRAM Using the Tigercat Advanced Oil Analysis Program on a regular basis is an excellent preventative maintenance tool.

Studies have shown that it is possible to receive a 10 to 1 payback when looking at the amount saved on repair costs to the amount invested in a scheduled oil analysis program. Some of the benefits of a sampling program include: •

Detect problems early before they become major catastrophic failures.

•

Better ability to schedule downtime and forecast cost of repairs.

•

Monitor maintenance schedules and practices and confirm that the required maintenance is being done on time.

•

Increase used equipment value by providing proof of proper maintenance.

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

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

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.

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

Contact your Tigercat Dealer Parts Department to order Kits.

Tigercat E625C Skidder

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

••

MAIN 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 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 When welding secure ground connection as close to working position as possible to prevent arcing across machined surfaces or through bearings Clean away all branches, bark and chips.

Clean up all traces of oil to avoid fires

CHECK EMERGENCY EXITS MONTHLY~ 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.

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.

• •

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.

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.

Tigercat E625C Skidder

Lubrication and Maintenance AIR CLEANER UNLOADER VALVE

IMPORTANT

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.

For peak engine performance and maximum fuel economy, please ensure that the air inlet hood or air precleaner is regularly checked and cleaned as required. All intake air tubes and clamps should be thoroughly inspected on a regular basis and any damaged or missing components should be replaced immediately.

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.

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 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. Later machines may be equipped with a switch used to send a signal to the computer control system in the event of a filter restriction.

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.

SAFETY ELEMENT

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. 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.

1. Have operator lift the dozer blade off the ground and then rapidly raise and lower blade several times to "bounce" machine.

3. Remove both retaining pins from the articulation lock. Relocate articulation lock between front and rear chassis. Line up holes at each end of articulation lock with holes in chassis’ and secure in place with both retaining pins.

2. As machine bounces, check for motion between the front and rear chassis frame lugs. Also check for a "clunking" sound at the center joint area.

3. Movement between front and rear chassis lugs or clunking of the pivot indicates a loose joint and preload must be checked.

GRAPPLE SNUBBER MAINTENANCE 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

625C-12

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.

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.

Lubrication and Maintenance SYSTEM TEST This system should be tested once every month by turning the shut-off valve ON and expelling water from the hose end nozzle. A very forceful discharge of water should be obtained. If the water does not come out with force (with pressure gauge reading 60 psi [4 Bar]) the system needs to be PURGED. Refer to PURGING PRESSURIZED WATER SYSTEM in THIS SECTION.

DOZER BLADE

••

•• •

After testing, the tank must be refilled and pressurized to 60 psi (4 Bar). Refer to the following FILL AND CHARGE procedure. This FILL AND CHARGE procedure should be carried out yearly.

HOSE STORAGE COMPARTMENT

SHUT-OFF VALVE IN CLOSED POSITION

620C-41

FILL & CHARGE PRESSURIZED WATER SYSTEM 1. Open water shut off valve and completely discharge all water and compressed air from the tank via the hose end nozzle.

PRESSURIZED WATER SYSTEM

A water tank is incorporated into the dozer blade and is pressurized to 60 psi (4 Bar). A valve controls the flow of water from the tank to a hose located in the hose storage compartment on the dozer blade.

CAUTION

The control valve incorporates an air charge valve, a pressure gauge and a relief valve on the outlet side of the valve. A ball valve is installed on the outlet side of the valve and is used to shut off the water supply to the hose. This shut-off valve should be in the CLOSED position when the system is not in use.

The pressure gauge on the valve should read 60 psi (4 Bar) check system pressure daily.

Never remove fill plug before depressurizing tank or injury may result. This fill plug incorporates a vent hole to release air pressure from the tank before the threads disengage. Do not replace this fill plug with any substitute.

2. Slowly unscrew fill plug two full turns. Any remaining air in the tank will be heard expelling from the special fill plug. Do not remove fill plug until all air has been expelled.
