SAE STANDARDS FOR MACHINE OPERATOR PROTECTIVE STRUCTURES.............................................vii

Tigercat 602 Skidder

Introduction

SAE STANDARDS FOR MACHINE OPERATOR PROTECTIVE STRUCTURES THE OPERATOR ENCLOSURE FOR THIS MACHINE MEETS THE FOLLOWING STANDARDS: • ISO 8082:2003 ROLL OVER PROTECTION STRUCTURES (ROPS) • ISO 8083:2006 FALLING OBJECTS PROTECTION STRUCTURES (FOPS) • ISO 8084:2003 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: • Written approval of repairs or modifications signed by the Tigercat Engineering Manager; or • 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 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.

• A load of logs will change the handling and stability of the skidder.

• Always be prepared to dump the load in case of emergency.

WARNING

• Never approach an unstable log from the downhill side.

• Do not winch in a load at a sharp angle. This could cause your machine to tip over.

• When the engine is running, DO NOT allow anyone in areas of the machine where they may be crushed by moving components.

• Maintain a safe operating distance between the machine and workers and all other personnel. It is the duty of the operator to ensure that no person approach the machine while in use, the risk zone is 60 m (200 feet).

WARNING • Never operate the boom or grapple (if equipped) over the heads of bystanders.

• When reeling in winch cable, make sure all ground personnel are at a safe distance, at least 1 1/2 times the working length of the cable, in case of rolling logs or whipping cables.

• Ground personnel should maintain a safe distance, at least 1 1/2 times the working length of the cable, from a winch cable under tension.

• When operating the winch with ground personnel, keep the personnel in view at all times and ensure ground personnel are never allowed to be in line with the load.

• Do not overload your skidder as this can create an unstable condition and cause a roll-over.

CAUTION Do not open cab doors or window screens when cab is on a slope. The doors and screens are heavy and could swing out with considerable force. Anyone in the path of swing could be injured. Anyone opening the door or screen and holding on to it could be pulled out of the cab and injured.

• Before moving the machine, lift the the dozer blade and grapple (if equipped) off the ground and keep them high enough to clear obstacles such as stumps.

• Check for correct tire air pressure. If the pressure is too low it will result in swaying. If the pressure is too high it will result in bouncing. Refer to TIRE PRESSURES in SECTION 3.

• If the machine is to travel on public roads, use accessory lights (when installed) and other caution devices to alert operators of other vehicles of your presence. Ensure your machine meets all regulatory requirements.

• Use only prearranged and approved signalling practices.

Introduction

FLUID INJECTION INJURY

IN THE EVENT OF ANY SUSPECTED FLUID INJECTION INJURY:

WARNING

• REPORT THE INJURY TO YOUR SUPERVISOR IMMEDIATELY.

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

• SEEK PROFESSIONAL MEDICAL ATTENTION IMMEDIATELY.

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.

The best defence against suffering the effects of fluid injection is to prevent the accident from occurring.

When searching for possible fluid leaks:

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

• Never search for leaks with your bare hands. Always wear thick protective gloves.

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

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

• Be sure to wear safety goggles for eye protection.

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

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

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

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

When performing any service work: • Turn OFF 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.

• Hoses must always be rated for the pressures to which they will be subjected.

• Never use any hoses you suspect could be defective.

1.19

Safety

Tigercat 602 Skidder

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: • 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.

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

• Wear proper protective equipment 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.

• Make sure protective shrouds are installed on all grease gun nozzles as safety devices.

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

• Replace any defective grease fittings with new fittings immediately.

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

Introduction

LIGHTNING SAFETY AWARENESS

LIGHTNING SAFETY

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

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

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

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

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

• Observe local weather conditions.

• Alert all other members of the crew when a possible lightning threat develops.

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

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

Thunder always accompanies lightning. When lightning occurs, the air through which it travels is instantaneously heated to a temperature more than 28,000°C (50,000°F).

The air expands rapidly due to this heating, then quickly contracts as it cools. It is this contracting shock wave that we hear as thunder.

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

1.21

• Anticipate a high-risk situation and take action early by moving to a low-risk location. Do not hesitate. If there is lightning, you are in danger.

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

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

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

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

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

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

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

Tigercat 602 Skidder IF INSIDE A MOTOR VEHICLE OR FULLY ENCLOSED ROPS EQUIPMENT CAB: • Under no circumstances whatsoever step outside of the vehicle or off the equipment to move to another shelter. Very dangerous electrical pathways to ground may go through you.

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

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

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

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

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

NOTE: The rubber tires on motor vehicles and heavy equipment do not increase safety from lightning strikes.

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

WHAT TO DO IF YOU ARE OUTSIDE AND SEE LIGHTNING OR HEAR THUNDER IF YOU CAN, GET INSIDE: Run to the nearest building, motor vehicle or fully enclosed ROPS equipment cab immediately. Being anywhere outside is not safe.

IF INSIDE A BUILDING: • Don’t watch the lightning storm from open windows or doorways. Stay in inner rooms.

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

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

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

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

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

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

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

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

• Avoid entering any small enclosures or shelters.

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

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

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

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

• Do not use the telephone except for emergencies.

1.22

Tigercat 602 Skidder

Introduction

WHAT TO DO IF YOU FEEL YOUR SKIN TINGLING, YOUR HAIR STANDS ON END, LIGHT METAL OBJECTS VIBRATE OR YOU HEAR A CRACKLING SOUND: • Lightning is probably about to strike. You only have a few seconds to act.

• Put your feet together. Crouch down like in a baseball catcher’s position. Hold your head down.

Cover your ears to protect them against the noise of the thunder.

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

WHAT TO DO IF A CO-WORKER HAS BEEN STRUCK BY LIGHTNING: • The victim does not carry any electrical charge.

There is no danger to anyone helping this person.

You can touch him or her immediately.

• Call your local emergency response telephone number immediately.

• If the victim has no pulse, their heart has stopped or they have stopped breathing, call for professional medical help immediately and then begin administering appropriate first aid. Use a portable defibrillator if one is available (as required).

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

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

Safety

FIRE PREVENTION

When working in a forest environment, it is impossible to prevent combustible debris from collecting in tight corners of the machine. This debris may cause a fire.

However, when mixed with fuel, oil or grease in a hot or confined place, the danger of fire is greatly increased.

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

The following guidelines will help to keep your equipment up and running efficiently and keep the risk of fire to a minimum: • Maintain a CHARGED fire extinguisher on the machine at all times and KNOW HOW TO USE IT. • 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 COOLER PACKAGE in SECTION 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 is vital after blow-off to ensure thorough cleanliness. 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 smoulder. If dislodged this smouldering debris can fall into other areas of the machine and thereby spread a fire.

Tigercat 602 Skidder • 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.

• 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.

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

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

• Use only non-flammable solutions for cleaning the machine and components.

• 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.

• 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.

• Park the machine at least 15 m (50 ft) away from other equipment at the end of each shift.

• Never leave the machine parked with 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.

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

1.24

Tigercat 602 Skidder

Introduction

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

WHAT TO DO TO PREPARE FOR A MACHINE FIRE

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

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

• 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.

• All hand held fire extinguishers must be 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 FIRE EXTINGUISHER MANUFACTURER'S DOCUMENTATION. • Any pressurized water systems on the machine (if applicable) must be charged and in working order. Refer to PRESSURIZED WATER SYSTEM MAINTENANCE in SECTION 3.

• You must 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.

• 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.

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

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

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

NOTICE Equipment fires adversely effect your ability to log, may increase your insurance premiums dramatically or prevent you from obtaining insurance coverage at all.

1.25

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

• The fire detection system* must be in working order.

Refer to FIRE DETECTION SYSTEM in SECTION 2.

• The fire suppression system** must be charged and in working order. Refer to FIRE SUPPRESSION SYSTEM (OPTIONAL) in SECTION 2.

• You must be familiar with the recommended procedures for fire contained in the emergency action plan of your company.

Safety • You must 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: • Workers assigned to fire fighting duties must be physically capable of performing them safely and effectively.

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

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

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

• After you have received the training as outlined above, you must 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.

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

Tigercat 602 Skidder BEFORE DECIDING TO FIGHT THE FIRE, BE CERTAIN: 1. The fire is small and not rapidly spreading.

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

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

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

5. Be aware, hoses containing engine coolant, diesel fuel or hydraulic hoses could fail during a fire. If this happens, hot coolant, fuel or oil could possibly be ignited by the fire.

6. If possible a dry chemical fire extinguisher or fire suppression system** should be used first to fight a machine fire. Then immediately afterwards use the pressurized water hose supplied with the machine (if applicable) or a pressurized water extinguisher (if available). A fire suppressed by dry chemical may re-ignite from the heat retained by any debris or hot machine components in the area. The water will cool the area, reducing the chances of re-ignition.

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

• 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.

WHAT TO DO WHEN A MACHINE FIRE OCCURS

• 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.

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

2. Turn OFF the engine.

3. Activate the fire suppression system**.

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

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

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

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

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

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

1.26

Tigercat 602 Skidder

Introduction WHAT TO DO AFTER A MACHINE FIRE HAS OCCURRED • Before returning the machine to work: • Make sure the cause of the fire is determined and all appropriate repairs are completed.

• Make sure the fire detection system* or the fire suppression system** is properly serviced and in working order (if applicable).

• All extinguishers used in fighting the fire must be replaced or recharged.

• 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.

800051

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.

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

Safety DRY CHEMICAL CLEANUP PROCEDURES Both ABC dry chemical fire extinguishers and fire suppression systems discharge a chemical powder to extinguish the fire. The chemical makeup and the small particle size of the powder as well as the force of the discharge all contribute to the fire fighting capability.

These same characteristics also permit the powder to penetrate into and fully cover all components in the vicinity of the discharge.

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

Tigercat 602 Skidder • In areas exposed to heat during the fire, the dry chemical powder will melt forming a coating that cakes or crusts on all surfaces. To break down the caked dry chemical, spray or wash these areas with a 50/50 mixture of hot water and Isopropyl alcohol.

Allow this mixture to stand in place for several minutes. 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.

NOTE: 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.

• All electrical systems must be completely deenergized prior to any cleanup.

• 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.

• In areas exposed to moisture, the dry chemical powder will combine with water to form a mildly acidic paste.

NOTE: 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 three parts hot water to one part baking soda. Allow this mixture to stand for several minutes before rinsing with warm water. Wash the area with a mild soap and water solution. Rinse thoroughly with water.

Blow-dry to remove all residual water. 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.

Forward Facing Foot Pedals (Seat Facing Front Of Machine) A Travel/Engine Speed Pedal B Brake Pedal

TRAVEL/ENGINE SPEED PEDAL (ROTATING SEAT & JOYSTICK STEERING) • Press the foot pedal to drive in the direction selected on the direction selection switch on the left joystick.

The position of the foot pedal is directly proportional to the travel/engine speed of the machine.

NOTE: A backup alarm will sound when travelling in reverse based on the position of the operator's seat.

Refer to LEFT JOYSTICK – DIRECTION SELECTION SWITCH in THIS SECTION. This function can also be performed with the travel/ engine speed trigger. Refer also to CAB CONTROLS – TRAVEL/ENGINE SPEED TRIGGER in THIS SECTION.

Rear Facing Foot Pedals (Seat Facing Rear Of Machine) A Travel/Engine Speed Pedal B Brake Pedal

BRAKE PEDAL (ROTATING SEAT & JOYSTICK STEERING) • Press the foot pedal to apply the hydraulic brakes in the front axle. This will also apply braking to the rear axle since they are mechanically locked together by the drive shafts and transmission.

NOTE: As a safety precaution before working on or around the machine; After the engine has been turned off, depress this pedal repeatedly until there is no pedal resistance to relieve any pressure that may be stored in the hydraulic system. This may take a minimum of 150 applications.

Check service brake for proper operation daily. Refer to SERVICE BRAKE – CHECKING BRAKE AND ACCUMULATOR FOR PROPER OPERATION in SECTION 3.

FORWARD FACING PEDALS AND REAR FACING PEDALS (ROTATING SEAT & JOYSTICK STEERING) The rotating seat cab is equipped with two sets of pedals one set forward facing and the other set rear facing.

2.12

Tigercat 602 Skidder

Controls & Operation

Note that control of machine travel is automatically transferred by the computer control system from the forward facing travel/engine speed pedal to the rear facing travel/engine speed pedal based on the position of the operator's seat. Both brake pedals operate regardless of seat position.

For safe operation of all controls the operator's seat must be locked in either the forward facing or rear facing position. Refer also to ROTATING SEAT KICK LEVER in THIS SECTION. FRONT AND REAR ORIENTATION NOTE: The dozer blade is considered to be at the front of the machine. The attachment is considered to be at the rear of the machine. Therefore in the forward facing position the operator's seat is facing the dozer blade and in the rear facing position the operator's seat is facing the attachment.

STEERING • Move the joystick to the RIGHT* to articulate the machine to the RIGHT* .

• Move the joystick to the LEFT* to articulate the machine to the LEFT* . *NOTE: Steering control is automatically adjusted by the computer control system based on the position of the operator's seat. Therefore LEFT articulation and RIGHT articulation as described above are considered to be left and right as viewed by the operator either from the forward facing seat position or the rear facing seat position.

It should also be noted that the machine steering invert function can be disabled. Refer to COMPUTER – MESSAGES - INFORMATION – MACHINE STEERING INVERT DISABLED and COMPUTER – ADJUSTMENT MENU - SERVICE SETTINGS – STEER INVERT (JOYSTICK STEERING ONLY) in THIS SECTION. This machine is equipped with variable ratio load sensing steering. The speed that the vehicle responds to the steering control input will vary, depending on the speed at which the steering control is moved.

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 vehicle's direction.

For safe operation of all controls the operator's seat must be locked in either the forward facing or rear facing position. Refer also to ROTATING SEAT KICK LEVER in THIS SECTION.

DIRECTION SELECTION SWITCH (ROTATING SEAT & JOYSTICK STEERING) This switch selects the direction of travel for the travel/ engine speed pedal in use (either forward facing or rear facing).

This is a three position switch.

• Place switch in the forward position to travel in a FORWARD* direction .

• Place switch in the centre position for neutral.

• Place switch in the rear position to travel in a REVERSE* direction . *NOTE: Control of machine travel is automatically transferred by the computer control system from the forward facing travel/engine speed pedal to the rear facing travel/engine speed pedal based on the position of the operator's seat. Therefore FORWARD and REVERSE as described above are considered to be forward and reverse as viewed by the operator either from the forward facing seat position or the rear facing seat position.

WARNING

FOR CARCO WINCH

When operating Carco winches the load MUST be removed from the cable before placing the winch control in the freespool position to avoid damage to the winch which could cause a safety hazard.

Place the winch select switch (to the left of the lever) in the I (ON) position to activate the winch control lever.

• Push and hold the winch control lever FORWARD to release the dynamic brake for dropping a load on the fly or drive away from a load with slight tension on the cable. The control lever will return to the centre neutral position when released.

Attempting to engage or disengage the freespool function with a load on the cable will cause damage to clutch halves, piston, final planetary gearing and/or output shaft. Damage to freespool components can cause a sudden loss of load control which could result in death or serious injury.

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

• Pull and hold the winch control lever BACK to wind in the winch cable . The control lever will return to the centre neutral position when released.

Placing the winch select switch (to the left of the lever) in the (FREESPOOL) position permits the cable to unwind freely. The cable can then be pulled from the drum by the operator by hand. The freespool function is intended for use in pulling the cable by hand only and must not be used when the cable is loaded. Improper use of the freespool function will result in damage to the winch.

FAN CONTROL - SWITCH (IF EQUIPPED - VARIABLE PITCH FAN)

The auto clean cycle is adjustable through the computer control system menu (ADJUSTMENT MENU – FAN SETTINGS). Refer also to COMPUTER – ADJUSTMENT MENU - FAN SETTINGS in THIS SECTION.

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 cooler package AUTOMATIC Position - AUTOMATIC is the normal operating position for the fan control switch.

When the switch is in the AUTOMATIC position, the fan will operate completely in an automatic mode.

The computer control system will automatically control the fan pitch to minimize system energy losses and improve performance based on the temperature of the charge air, engine coolant and hydraulic oil. The computer system automatically adjusts fan air flow to the minimum required level to maintain optimal operating conditions.

Not Used For This Application Not Used For This Application Not Used For This Application Air Conditioner Switch Air Source Switch Temperature Control Fan Control, Ventilation Fan Control Switch (Variable Pitch Cooler Package Fan)

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

This is a three position switch, labeled / / (FULL ON/ AUTOMATIC/ CLEAN).

•

N

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.

•

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 cooler package and air conditioning systems. In low temperature operating conditions fan air flow is reduced, as less cooling is required for efficient operation of the cooler package.

2.30

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.

•

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.

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

The auto clean cycle is adjustable through the computer control system menu (ADJUSTMENT MENU – FAN SETTINGS). Refer also to COMPUTER – ADJUSTMENT MENU - FAN SETTINGS in THIS SECTION.

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

GRAPPLE SKIDDING

CABLE SKIDDING:

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

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

2. 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.

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. Lower the dozer blade and grapple (if equipped) to the ground to anchor the machine.

Grapple (if equipped) may have to be raised, depending on winching angle and land terrain.

3. 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.

Note that cab doors must be closed and parking brake disengaged to operate the winch in function.

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

7. Raise the grapple (if equipped) 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 and winch the load back into the butt pan.

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

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.

The skidder may be transported with the wheels on or off.

• Additional chains may be installed on the two tow lugs (front of unit) and on the bottom cab access steps.

With wheels on:• DO NOT remove air from tires, this will result in damage to the tires!

CAUTION As a fire prevention measure, AFTER transporting (trucking) a machine from one job sight to the next, open all doors and access panels and blow off any debris that could have re-positioned itself onto the engine and exhaust parts due to wind turbulance caused by the journey. Refer also to FIRE PREVENTION in SECTION 1..

With wheels off:• If the wheels are removed the machine must be blocked so that the centre joint is one inch or more above the truck bed.

With the wheels on or off:• The dozer blade must be down on the truck bed.

• The grapple (if equipped) must be closed and lowered to the truck bed.

IMPORTANT !

When transporting the machine, chains must be used to prevent forward, reverse and side to side movement of the machine.

Do not secure the machine to the truck ANYWHERE near the centre joint area as this can seriously damage the centre joint.

FOLLOW-UP SAMPLES

Every Oil Change (1000 Hours or 6 Months)

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 in relation to the amount invested in a scheduled oil analysis program. Some of the benefits of a sampling program include:

Tigercat Fluid Analysis Kits are available from your Tigercat dealer parts department. If required, arrangements can also be made with your Tigercat dealer to supply and perform all of the required follow-up fluid samples.

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

TIGERCAT FLUID ANALYSIS KITS

• Detecting problems early and before they become major catastrophic failures.

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.

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

The same type of sample bottle can be used for all types of fluid testing including:

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

Hydraulic Circuits, Final Drives, Axles, Gearboxes, Engines, etc.

• 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.

The report is available as a mailed or faxed hardcopy, sent via e-mail or it can be viewed on the Internet.

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

3.5

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

Contact your Tigercat Dealer Parts Department to order Kits.

Lubrication and Maintenance FLUID SAMPLE COLLECTION PROCEDURES

Tigercat 602 Skidder HYDRAULIC OIL SAMPLES

Fill out the Sample Information Form (SIF) completely and accurately. When taking multiple fluid samples, fill out all of the required SIF forms in their entirety, prior to taking any fluid samples. Then, immediately package each completed SIF form together with the matching fluid sample in the black outer shipping container as each individual sample is taken. This will reduce the possibility of mixing up or incorrectly identifying the SIF forms and 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 fluid sample taken.

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

602-031

Main Hydraulic Oil

A Hydraulic Sample Valve

• 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.

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

• 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.

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

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

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

• DO NOT allow any airborne dirt, etc., to enter the sample bottle.

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

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

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

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

GENERAL

• 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 turned OFF immediately and not put back to work until the necessary repairs have been completed.

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

• Always have a fire extinguisher at hand.

• Always clean around fill caps before checking or adding fluids.

• For safety, when leaving the cab or leaving the machine unattended or during service, always lower the dozer and grapple (if equipped) to the ground.

• Always release hydraulic pressures and clean around hydraulic fittings before breaking connection.

Plug or cap immediately.

• Always install the door safety struts when working on the machine.

• Always clean up spills as soon as possible.

• Always clean the fire suppression system sensors.

• Always use clean oil and containers.

CHECK EMERGENCY EXITS MONTHLY

• Drain dirty oil while still warm.

• Two 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.

• 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.

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

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

• Refer to EMERGENCY EXIT– MAINTENANCE GUIDE in THIS SECTION for the procedure.

• Always clean up oil spills on walking surfaces in the engine enclosure immediately.

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

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

• Always clean away all branches, bark and chips.

Clean up all traces of oil to avoid fires.

• 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.

Lubrication and Maintenance

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

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

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

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

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

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

3. 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 turn OFF the engine before discharging the fire suppression system.

Refer to FIRE PREVENTION in SECTION 1 for additional information.

The hydraulic oil cooling circuit contains a triple filter head. It is recommended that all machines use two different filter elements: • 2 white, Tigercat high performance, full flow hydraulic oil filter element • 1 blue, Tigercat water absorbing, full flow hydraulic oil filter element.

There is a bypass valve built into each filter head preset at 25 psi (1.7 bar). 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. A filter restriction sensor also sends a signal to the computer control system.

BATTERY CARE

FUEL FILTERS

Tigercat uses two types of batteries dependant on the machine application, model and design.

This machine is equipped with two fuel filters. The engine fuel filter and the fuel filter/water separator. The fuel filter/water separator is a combination unit, with a replaceable fuel filter and a removable water sediment bowl on the bottom of the unit. The water sediment bowl is only replaced if it becomes damaged or nonfunctional. f

• Absorbed Glass Mat (AGM) • Flooded Lead Acid (FLA).

NOTICE Before charging the battery, it is important to identify which type of battery you have.

Always read and follow the battery and charger manufacturer's instructions prior to connecting or charging a battery.

All batteries are sensitive to overcharging. Charging or maintaining AGM batteries requires the use of a smart charger with an AGM setting. The peak charging voltage for AGM batteries varies slightly between battery manufacturer's. Exceeding this voltage will cause permanent battery damage. Refer to the BATTERY MANUFACTURER'S charging instructions for more information.

ENGINE FUEL FILTER AND FUEL FILTER/ WATER SEPARATOR IMPORTANT !

Failure to service and replace filters at the proper intervals specified in the manufacturer's manuals, could cause damage to the machine and result in the product warranty becoming NULL and VOID. Check Tigercat parts catalog for replacement filters

NOTICE

Charging or maintaining FLA batteries requires the fluid levels to be checked. Refer to BATTERY MANUFACTURER'S instruction.

Also refer to BATTERY BOOSTING in SECTION 2.

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

Use of filters other than genuine Tigercat replacement filters is not recommended. Replace filters at the recommended time intervals. Refer to scheduled maintenance in this section.

IMPORTANT !

Filters that are an integral part of the engine (fuel and lubricating oil) should be serviced and replaced according to the engine OPERATION AND MAINTENANCE MANUAL. The engine fuel injection system requires extremely clean fuel. To accomplish this, the engines typically use filters with a finer micron rating.

These engines use filters with a very fine micron rating.

If the fuel supply is dirty, the fuel filter must be replaced 3.36

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.

AIRCLEANER

A Primary Element B Outlet Tube C Safety Element

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.

NOTE: This does not apply to oil filters.

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

IMPROPER SERVICING

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

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.

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

6. Inspect the new filter for damage.

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

8. Inspect connections and ducts for air tight fit. Ensure that all clamps, bolts and connections are tight.

Check rubber elbows for splits or wear points and replace as needed. Leaks in these locations send dust directly to the engine.

THE AFTERTREATMENT SYSTEM AND ITS RELATED COMPONENTS ARE APPLICABLE TO TIER 4F ENGINES ONLY.

C

AFTERTREATMENT SYSTEM (DENOX 2.2 SYSTEM - TIER 4 FINAL)

F

The engine on this machine is equipped with a combination Diesel Oxidation Catalyst (DOC) and high efficiency Selective Catalytic Reduction (SCR) aftertreatment system to limit the nitrogen oxide exhaust gas values (NOX) to meet Tier 4f emission standard requirements with low fuel consumption. This process is electronically controlled by the DENOX 2.2 system.

The diesel oxidation catalyst (DOC) uses oxidation at high temperatures to convert carbon monoxide (CO), hydrocarbons (HC) and the soluble organic fraction (SOF) of diesel particulates into inert compounds, carbon dioxide (CO2) and water vapour (H2O). In addition the DOC converts nitrogen oxide (NO) into nitrogen dioxide (NO2). Increased NO2 levels enhance the performance of the SCR catalyst at low temperatures and increase the effectiveness of the DOC/SCR aftertreatment system as a whole.

The high efficiency SCR process is based on a series of chemical reactions which involve the reaction of ammonia with the oxygen in the exhaust gas to reduce nitrogen oxides (NOX) in the exhaust gas by transforming it into inert compounds: free nitrogen (N2) and water vapour (H2O). In addition the high efficiency catalytic converter includes a clean up catalyst (CUC) which reduces any excess ammonia (NH3) which may result from the SCR process.

IMPORTANT !

When cleaning the machine with pressurized water it is important to avoid getting water directly or indirectly into the exhaust tube. Water in the exhaust tube will damage sensors and SCR system components and affect the proper operation of the aftertreatment system and the engine.

IMPORTANT! The engine should not idle longer than 1 hour.

Damage to the emission control system will result.

When this machine idles for an extended period, excess hydrocarbon buildup is created in the DOC/ SCR aftertreatment system. Burn off of excess hydrocarbon, at full load, immediately after a long idle period, generates excess heat which causes damage to emission control system components.

The aftertreatment system is electronically managed by the DENOX 2.2 system incorporated into the engine control unit (ECU). The ECU calculates and adjusts the flow rate of the DEF solution into the system based on current engine speed, torque delivered, exhaust temperature, amount of nitrogen oxides and ammonia present.

The exhaust passes through the diesel DOC which uses oxidation at high temperatures to convert carbon monoxide (CO), hydrocarbons (HC) and the soluble organic fraction (SOF) of diesel particulates into inert compounds, carbon dioxide (CO2) and water vapour (H2O). It also converts nitrogen oxide (NO) into nitrogen dioxide (NO2) which enhances the performance of the SCR catalyst.

The supply module pump picks up the DEF solution from the tank and sends it under pressure to the dosing module (DEF injector) to be injected into the exhaust at the outlet of the DOC and pass through the mixer tube upstream of the catalytic converter.

3.47

Catalytic Converter CUC NOX Sensor NH3 Sensor Engine Temperature Sensors NOX Sensor Exhaust Flap Engine ECU DEF Dosing Module Filter

The first phase of the SCR process takes place in the first part of the catalytic converter: high temperature exhaust gas evaporates the DEF solution instantly and, by hydrolysis, converts it into ammonia (2NH3) and carbon dioxide (CO2).

Evaporation of the solution lowers exhaust gas temperature, bringing it closer to the optimum temperature required by the process.

The exhaust fumes and ammonia at the proper reaction temperature, are introduced into the catalytic converter, where the second phase of the process takes place: by reacting with the oxygen in the exhaust gases the ammonia is converted into free nitrogen (N2) and water vapour (H2O).

Finally the high efficiency catalytic converter incorporates a clean up catalyst (CUC) which reduces any excess ammonia (NH3) which may result from the SCR process.

HUMIDITY SENSOR

A

620E-089

The humidity sensor is located on the air intake just past the air cleaner. This sensor monitors the temperature and humidity of intake air sending signals to the DENOX 2.2 control system. This information is used to calculate the amount of DEF to be injected into the system.

602-060

A Catalytic Converter

The catalytic converter is located on the left side of the engine compartment. Chemical reactions inside the catalytic converter reduce nitrogen oxides (NOX) in the exhaust gas.

The catalytic converter is equipped with soundproofing material and replaces the exhaust silencer. It incorporates both the selective catalytic reduction (SCR) and the cleanup catalyst (CUC) components of the aftertreatment system.

The first phase of the SCR process takes part in the first part of the catalytic converter: high temperature exhaust gas evaporates the DEF solution instantly and, by hydrolysis, converts it into ammonia (2NH3) and carbon dioxide (CO2).

Evaporation of the solution lowers exhaust gas temperature, bringing it closer to the optimum temperature required by the process.

The exhaust fumes and ammonia at the proper reaction temperature, are introduced into the catalytic converter, where the second phase of the process takes place: by reacting with the oxygen in the exhaust gasses the ammonia is converted into free nitrogen (N2) and water vapour (H2O).

Finally the high efficiency catalytic converter incorporates a clean up catalyst (CUC) which reduces any excess ammonia (NH3) which may result from the SCR process.

A Electronic Control Unit B Sensor

The inlet NOX sensor is mounted upstream of the diesel oxidation catalyst. The outlet NOX sensor is mounted at the outlet of the catalytic converter. The NOX sensors detect and send information about the dosing of DEF solution and the efficiency of the catalytic converter to the DENOX 2.2 control system. This information is used to calculate the amount of DEF to be injected into the system and to monitor DOC/SCR aftertreatment system operation.

Each NOX sensor consists of ceramic sensor and an electronic control unit linked by a cable. The sensor detects the concentration of nitrogen oxides in the exhaust. The sensor, cable and control unit are considered to be one part for service/replacement purposes.

NOTE: cable length cannot be changed as this will affect the proper operation of the sensor.

IMPORTANT! When checking or replacing any sensor or plugs in the exhaust or the aftertreatment system it is important to use only approved anti-seize as specified by Tigercat.

Use of non-approved compounds can affect the operation of the NOX sensor and a malfunction of the DOC/SCR aftertreatment system. This may result in poisoning of the catalytic converter and require replacement of expensive aftertreatment system parts.

GRAPPLE SNUBBER MAINTENANCE SNUBBER HOUSING 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 housing for daily lubrication. Be sure to lubricate all the grapple snubbers on your machine.

Proper lubrication prevents excessive clutch wear.

IMPORTANT !

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

ADJUSTING SNUBBER TENSION Each snubber should be adjusted such that: • It is capable of stopping the grapple within one full swing.

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.

615C-022

Snubber Housing

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

1. Park the machine on level ground.

2. Lower the grapple and dozer blade to rest firmly on the ground.

3. Engage the parking brake.

4. Turn OFF the engine.

5. Remove the ignition key.

6. Turn OFF the battery disconnect switch.

7. Block wheels.

8. Install the articulation lock bar.

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

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

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

• Reinstall bolts and tighten in a crisscross pattern.

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

WINCH MAINTENANCE - CARCO WINCH OPERATION The winch is controlled through the winch select switch and the winch control lever. The winch select switch is used to activate/deactivate the winch control lever and to activate the winch freespool function. The winch control lever when activate is used to wind in the winch.

The Carco winch functions differently than other winches operators may be familiar with. The following are notes for Carco winch operators to remember: • Do not use freespool (mechanical jaw clutch) to drop a suspended load or if there is tension on the cable • Use drive away (dynamic brake clutch) to lower a load, drive away from a load, to release tension in a cable.

• After using freespool or drive away allow the clutches to fully re-engage before winching in. This is especially important when the oil is cold.

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

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

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

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

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

IMPORTANT !

When cleaning the machine with pressurized water it is important to avoid getting water directly or indirectly into the exhaust tube. Water in the exhaust tube will damage sensors and SCR system components and affect the proper operation of the aftertreatment system and the engine.

Tigercat 602 Skidder INSPECTION AND MAINTENANCE Daily inspection and maintenance is essential to confirm that the window’s ability to protect the operator has not been compromised.

• Inspect all windows daily and immediately after any impacts.

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

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

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

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

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

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

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

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

RESISTANCE TO CHEMICALS

RESISTANCE TO WATER

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.

Polycarbonate material has good resistance to water up to approximately 65°C (150°F). Above this temperature the effect of water is time-temperature related. This means that the higher the water temperature, the shorter the time before the polycarbonate is adversely affected.

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

3.83

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.

Lubrication and Maintenance CLEANING INSTRUCTIONS 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.

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

Tigercat 602 Skidder CAUTIONS • 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 nonaerosol 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.

• 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.

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

CONCEALING HAIRLINE SCRATCHES

SIDE WINDOW SCREENS

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 A

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.

620E-031

Side Window Screen

A Window Screen Handknob

• 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.

3.85

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

A handknob is provided on both the inside and the outside. By unscrewing either (not both) of these knobs, the screen will be free to swing out on the hinges.

Be aware that the screen will swing outwards with considerable force, if the door is open.

All handles should be hand tight only at all times.

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.

3.87

3. If necessary use the CLEAN function to reverse fan flow and clean debris from the machine's engine enclosure 4. In severe operating conditions manual cleaning of debris may be required.

5. If the problem persists check engine coolant and/ or hydraulic oil levels. Refer to OPERATING MACHINE – PRESTART CHECKS in THIS SECTION. 6. Return the fan control switch to the AUTOMATIC position and check for proper operation of the fan.

In the event of a problem with the automatic control system the fan control switch should be placed in the FULL ON position while the machine is operating until the fan control can be properly repaired.

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