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

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

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

Safety

Tigercat 724E Feller Buncher 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 315°C (600°F).

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

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

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

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

• Visually inspect any seals or gaskets which have suffered from heat damage; they will appear black and sticky. If these are found, DO NOT TOUCH!!!

Some advice which should be observed:

• Determine the material composition of any seals or gaskets, If fluoroelastomer 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.

• Avoid contact with oil, particularly heated oil.

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

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

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

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

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

• Don't put oily rags in your pockets.

• Oil soiled clothing should be changed as soon as possible.

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

• Always keep an extra pair of overalls handy, but not in the machine where it can become dirty.

SAFETY HAZARDS - OPERATING Maintain a charged fire extinguisher on the vehicle at all times and know how to use it.

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

• Avoid breathing in oil fumes.

Do not carry passengers either in the cab or anywhere else on the machine. The vehicle is provided with and approved for seating for the operator only.

• Wash hands and arms frequently, for example, at each meal break or as often as possible.

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

When moving the machine, watch that enough clearance is available on both sides and above the machine or any of its attachments. Extra clearance may be required particularly where the ground is uneven.

Approach with extreme caution any area where overhanging electrical power lines are present. Serious injury or death by electrocution can result if the machine or any of its attachments are not kept a safe distance from these lines.

1.6

Tigercat 724E Feller Buncher

Safety

Maintain a distance of 3 m (10 ft) between the machine or boom and any power line carrying up to 50,000 volts or less plus 10 mm (0.5 in) for each addition 1,000 volts above the 50,000 volt level.

WARNING Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

Wash hands after handling.

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

If the machine must be transported, make sure it is adequately secured to the transporting vehicle. Refer to the Vehicle Moving Instructions in SECTION 2 of the OPERATOR'S MANUAL

If acid is accidentally splashed into your eyes, flush immediately with clean water and get medical attention.

Do not attempt to charge a frozen battery; it can explode.

Turning OFF 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.

Before working on electrical systems, disconnect the battery as follows: 1. Turn OFF the battery disconnect switch in the cab.

2. Disconnect the negative starter motor cable from both battery posts.

3. Disconnect the positive master solenoid cable from both battery posts.

WARNING

Do not change any pressure or relief settings unless Tigercat authorized instructions have been obtained.

Diesel fuel or hydraulic fluid that is under pressure can penetrate the skin and cause serious personal injury, blindness, or death.

If any fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with treating this type of injury.

Use the proper tool for the job. Repair or replace worn or damaged tools, including lifting equipment, immediately.

• When opening or closing the power operated engine door, watch for personnel in door areas.

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.

• If the engine is running inside a building, make sure 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.

• Work in a ventilated area. If it is necessary to run an engine in an enclosed area, use an exhaust pipe extension to allow toxic exhaust fumes to be routed outdoors.

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

Pressure can be maintained in a hydraulic system long after the power source and pump have been shut down.

Lower the attachment to the ground, turn OFF the engine and relieve trapped pressure before performing work on components or disconnecting any hoses. Refer to PARKING BOOM illustration. The accumulators will self drain within two minutes of turning OFF the engine.

• Dispose of fluids properly. Do not pour fluids into the ground, stream, pond or lake.

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

• When performing required hydraulic checks and blade speed adjustments, install the saw blade guard. Refer to the instructions provided by the attachment manufacturer.

• Always read, understand and follow all operating safety precautions specified by the harvesting attachment manufacturer.

Explosive release of fluids from pressurized cooling systems can cause serious burns.

Turn OFF the engine. Only remove the coolant filler cap when it is cool enough to touch with bare hands. Slowly loosen the cap to the first stop to relieve pressure before removing the cap completely.

FLUID INJECTION INJURY

WARNING

WARNING

IN THE EVENT OF ANY SUSPECTED FLUID INJECTION INJURY:

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.

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.

• REPORT THE INJURY TO YOUR SUPERVISOR IMMEDIATELY. • SEEK PROFESSIONAL MEDICAL ATTENTION IMMEDIATELY. The best defence against suffering the effects of fluid injection is to prevent the accident from occurring.

WHEN SEARCHING FOR POSSIBLE FLUID LEAKS

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

• Be sure to wear safety goggles for eye protection.

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

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

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

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

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.

• 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.

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

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

Safety

WHEN PERFORMING ANY SERVICE WORK

GREASE INJECTION INJURY WHEN USING PNEUMATIC GREASE GUNS

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.

• 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.

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.

LIGHTNING SAFETY AWARENESS

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

WHAT IS A LIGHTNING STRIKE?

1. Designate a member of your crew to:

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

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

• Monitor daily weather forecasts • Observe local weather conditions • Alert all other members of the crew when a possible lightning threat develops 2. Don’t start or continue any work that cannot be stopped immediately, when a storm moves nearby.

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

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

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

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

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

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

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

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

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

LIGHTNING SAFETY

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

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

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.

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

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

1.22

Tigercat 724E Feller Buncher Heavy forestry equipment such as a skidder, loader, feller buncher, forwarder, etc. with a fully enclosed rollover protective structure (ROPS) cab take advantage of the skin effect and are therefore safe in electrical storms.

Safety 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.

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

• 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.

Note that the rubber tires on motor vehicles and heavy equipment do not increase safety from lightning strikes.

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

• 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.

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.

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

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

If inside a building: • Don’t watch the lightning storm from open windows or doorways. Stay in inner rooms.

• Do not use the telephone except for emergencies.

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

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.

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

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

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

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

1.23

Safety

Tigercat 724E Feller Buncher

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, start cardiopulmonary resuscitation (CPR) or mouth –to-mouth resuscitation immediately. Use a portable defibrillator if one is available.

• 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

FIRE PREVENTION

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

5. Inspect the machine regularly for any signs of diesel fuel or hydraulic system leakage. Check for worn or eroded fuel or hydraulic lines before starting up any equipment.

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.

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

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

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

1. Maintain a CHARGED fire extinguisher on the machine at all times and KNOW HOW TO USE IT. 2. Remove debris and blow out dust regularly from the air intake doors, engine radiator and charge air cooler, hydraulic oil cooler, diesel fuel cooler and air conditioning condenser core to prevent overheating of the engine and hydraulics and to maintain efficient operation of the machine. Refer to CLEANING A/C CONDENSER, OIL COOLER AND RADIATOR in SECTION 2 of the OPERATOR’S MANUAL. 3. Blow off all forest debris and fine organic material accumulated near hot engine exhaust components (turbocharger and exhaust manifold as well as exhaust pipes and muffler) at the completion of each work shift or more frequently when working in logging conditions where large amounts of combustible forest debris are present. Visual inspection after blow off to ensure thorough cleanliness is vital. Engine exhaust systems provide numerous small pockets where saw dust, small wood chips and other flammable forest debris can gather. Even small accumulations close to hot exhaust components can ignite and smoulder. If dislodged this smouldering debris can fall into other areas of the machine and thereby spread a fire.

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

9. Inspect the exhaust system daily for any signs of leakage. Check for worn, cracked, broken or damaged pipes or muffler. Also check for missing or damaged bolts or clamps. Should any exhaust leaks or defective parts be found, repairs must be made immediately. Engine exhaust leaks can cause fires.

Do not operate the machine until the exhaust leak is repaired.

10. During daily operation of the machine, the occurrence of exhaust leaks are usually accompanied by a change or increase in engine exhaust noise levels. These audible warnings cannot be ignored. Should any exhaust leaks occur during operation, the machine must be shut down immediately and not put back to work until the necessary repairs have been completed.

11. Park the machine at least 15 METERS (50 feet) away from other equipment at the end of each shift.

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

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

1.25

Safety

Tigercat 724E Feller Buncher

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

NOTICE

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

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

WHAT TO DO TO PREPARE FOR A MACHINE FIRE • Prevent the fire from happening in the first place by ensuring that all machine systems are frequently inspected and always well maintained.

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

• Ensure that any pressurized water systems on the machine (if applicable) are charged and in working order. Refer to PRESSURIZED WATER SYSTEM MAINTENANCE in SECTION 3 of THIS MANUAL. 16. Be cautious when smoking. An open flame, a lighted cigarette, etc., should not be permitted around any vehicle, especially during fuelling operations or when the fuel system is open to the atmosphere or when servicing batteries.

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

• 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.

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

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

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

• 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 fire extinguisher access holes in the doors of the machine.

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

1.26

Tigercat 724E Feller Buncher

Safety

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

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

• 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:

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

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

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

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.

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

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.

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.

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

• Ensure that after you have received the training as outlined above, that you know how to use the fire extinguisher, the pressurized water system (if applicable) and the fire suppression system** on your machine. There is not enough time available to read instructions during a fire emergency.

• 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.

• 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.

• 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.

WHAT TO DO WHEN A MACHINE FIRE OCCURS If operating the machine when a fire occurs:

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

1. Lower all working attachments to the ground.

2. Shut the engine off.

3. Activate the fire suppression system**.

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

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.

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.

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

Tigercat 724E Feller Buncher

Safety

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. 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.

FOREWORD SEVERAL TYPES OF HEADS INVOLVED

Tigercat wheel type feller bunchers (figure 1) and crawler feller bunchers (figure 2) can be supplied with several optional makes and models of high speed disc saw tree felling heads. Because each has certain advantages and disadvantages they are chosen where they best do specific types of work.

STORED ENERGY

OTHER INSTRUCTIONS

The saw blade stores energy from the hydraulic motor during the times between tree cuts so that it can supply up to 1000 hp during a 1 sec tree cut. However this rotational energy, if misapplied can result in wood materials or other objects being thrown strongly enough to cause damage and to hurt people.

It is also understood and expected that all instructions contained in service and operator's manuals for use and maintenance of Tigercat disc saw heads and other disc saw heads installed on Tigercat machines will be followed.

THE DANGERS

BE AWARE OF THE HAZARDS

There are at least these means by which a rotating disc saw can cause harm by throwing:

It is important that users of machines with disc saw felling heads are aware of certain safety precautions that need to be taken. In this section some previously unknown, unexpected safety hazards are illustrated and explained . These should be studied before use of the machinery and then reviewed again after use has begun.

• The normal throwing of chips from the cut.

• Soil particles are thrown from the ground.

• Loose chunks of wood encountered or produced are tossed by the exposed blade.

• Sticks and debris falling onto the blade or sliding across the blade are struck by the teeth and thrown.

SAFE PRACTICES

• Metal pieces from the blade or from objects encountered are thrown.

It is understood and expected that logging organizations and operators will develop and practice additional rules that suit (for example) particular conditions of terrain, trees, soil and job requirements. The information given here is intended to assist towards a quicker understanding of how and why things can happen when a high speed disc saw is in use; and hence to assist in development of safe operating practices.

• Wood pieces enter the saw housing and are expelled by the blade.

• In very peculiar cases the saw can throw long lengths of wood as spears.

It should not be assumed that all possible dangers have been discovered and described here.

HOUSING TYPES TYPE OF HOUSING MAKES A DIFFERENCE Since the configuration of the saw housing can affect the safety of its use we need to identify some particular types of housing shapes and guarding being used.

Figure 3 shows a typical commonly used saw housing plan where there is a continuous skirt around the saw except at a mouth opening where the trees are cut and taken. The skirt extends below the saw enough to intercept tangential throw. There are snouts on both sides of the mouth so that if pushed against the side of a felled tree or log the saw teeth will not contact the wood.

THROW ANGLE

SAW13

IF A SAW HEAD IS PUSHED AGAINST THE SIDE OF A FELLED TREE, SNOUTS PREVENT SAW TEETH FROM CONTACTING WOOD.

A.4

SAW17

Tigercat

Figure 4 shows another commonly used plan. It has no blade guarding snouts so that the saw blade teeth do protrude ahead of the housing. This may be preferred over figures 3 and 5 for dexterity in tree getting.

IF A SAW HEAD WITHOUT SNOUTS IS PUSHED AGAINST THE SIDE OF A FELLED TREE, THE SAW TEETH WILL CONTACT WOOD.

FIGURE 4: ANOTHER COMMONLY USED HOUSING PLAN WITH NO SNOUTS, BLADE TEETH PROTRUDE AHEAD OF THE HOUSING.

SAW15

In figure 5, there is a much longer snout on the ingoing side of the mouth, i.e., where the teeth of the rotating blade are entering the housing. The broad side of a log, if nudged, will not contact the saw teeth and more thrown material will be intercepted by the extra length of snout.

HOUSING TYPES CONTINUED In figure 6a and 6b there is an additional opening in the housing skirt. Openings in this location are sometimes provided for escape of wood chips produced by the saw teeth in the cut and being taken into the housing.

In figure 6c a guard has been added to the chip escape port so that tangential travel of chips and other material is intercepted as soon as it leaves the housing.

Each figure shows a shaded area where normally tangentially thrown material can escape from the saw housing. Deflected and dropped chips escaping below the bottom edge of the housing skirt are not included.

The areas and angles are not exact but do show that one head can be different from another.

It is important that the operator familiarize himself with the blade rotation direction, the effectiveness of any snout on the in-going side and which direction any chip escape ports allow material to fly.

Using High-Speed Disc Saws Safely ASSESSING THE POTENTIAL DANGERS ON THE JOB SITE

COMMENTS AND INSTRUCTIONS

The extent of danger from high speed disc saws on the logging operation has to be assessed on the job site, depending on how much other work activity is in the area and whether the operator can do his job of cutting and bunching with good control of throw patterns. Danger is greater if the saw is equipped with detachable, or fragile, or brittle teeth, or if the site contains stones or abandoned metal.

RECOGNIZING THE DANGERS While it may appear that these illustrated danger areas can be visually recognized on the job by observing how far chips fly during a cut, that is only true for chips and other light weight materials. Metal parts and wooden spears can be thrown to surprisingly greater distances.

Even distant personnel on the ground, in other vehicles, or in buildings are at risk if the throw is in their direction.

REGULAR MAINTENANCE Poor saw maintenance increases these dangers. Some designs that might allow fasteners to wear thin or fatigue and suddenly break, need thorough timely replacement procedures. It is important that the warning signs of missing saw tooth parts or the sounds of striking rocks be heeded and the operation adjusted to avoid danger.

DIRECTION OF THROW The direction of possible tangential throw for metal parts and stones is dependent on the housing configuration and might be expected to be the same as observed for the chips. However, these throws can occur at any time the saw is running, in whichever direction the angle of throw is pointed by boom geometry, not just when a cut is being made.

THROW DISTANCE The throw distance for metal pieces and stones, can be many times the distance shown by the pattern for chips.

More testing and data collection is needed to pin down a “safe distance” but if someone or something is in a place that can be seen by the operator and in the throw direction of a high speed disc saw, then the operation is not safe regardless of the distance.

SAFE OPERATING AREAS These saw heads must not be used in areas where the logging operation does not have control over the presence and movement of people. In particular, clearing of vegetation in urban and populated areas should not be done with a Tigercat manufactured or supplied high speed disc saw. High speed disc saw heads are intended for high productivity wood harvesting in areas remote from normal habitation. The possible presence of people and property within throw range and the likelihood of encountering scrap metal, wire fencing, steel posts and concrete must be respected.

A.7

Using High-Speed Disc Saws Safely

Tigercat

COMMENTS AND INSTRUCTIONS CONTINUED HIGH ANGLE WRIST ROTATION ABILITY When a felling machine is equipped with a high speed disc saw head with a high angle wrist rotation ability it should be determined that the limits of the boom, stick, tilt, wrist, upper leveling and any other freedoms, do not permit a direct throw at the operators cab during normal operation, see figure 7a. It is probably essential that the housing have a long snout on the throw side and that if a chip escape port is used it should be guarded.

With these high mechanical freedom arrangements there is a chance that an unforeseeable operator misadventure or equipment failure could result in an accidental direct or deflected throw at the operators cab, refer to figure 2 and 7b. The cab should be capable of resisting such accidental and ricochet throws. The velocity energy of metal or rock pieces leaving the blade is extremely high. The operators cab cannot be considered safe to routinely operate in the chip throw area, even if it has been especially constructed to prevent penetration by accidentally thrown objects.

Using High-Speed Disc Saws Safely

Tigercat In this last case tests have shown that if the piece of wood is backed-up by a solid slippery surface; and if the feed in is very fast; and if the piece of wood is long enough; then the tangential movement is a dangerous spear-like throw.

COMMENTS AND INSTRUCTIONS CONTINUED THROWING LONG WOOD PIECES Dangers from throws of long wood pieces are illustrated in figures 8 to 11.

Tests and experience have shown that when a high speed rotating saw is applied to a loose piece of wood, the wood is either blown or pushed away, without a throw. If the wood is held firmly in all directions and the saw advanced into it at any feed speed, cutting will take place. If the wood is only held against escape from the saw radially, but not held tangentially, then the wood will be both partly cut and partly moved tangentially.

Figures 8 and 9 show two ways that this might happen in the woods if using the saw head of figure 4 (where the throw contact can be long). A slab, still partly attached to a well backed-up tree bole and wet with sap, makes an ideally bad throw situation which could unintentionally occur in woods work. A small log in a pile of other logs might also be propelled out with enough length of continued contact to reach near saw tip speed.

A SMALL LOG IN A PILE OF OTHER LOGS MIGHT ALSO BE PROPELLED OUT WITH ENOUGH LENGTH OF CONTINUED CONTACT WITH THE BLADE TO REACH NEAR SAW TIP SPEED.

COMMENTS AND INSTRUCTIONS CONTINUED Figure 10 shows how a head with snouts does not allow a long throw contact. Although tests show that a short contact length on a long log or tree butt does not result in a spear like throw, this action should nevertheless be avoided because abnormally large chips are sometimes produced and thrown.

SAW BLADE THROW GAP Saw blades have gaps between adjacent teeth and holders to permit installation and removal of the teeth and to provide spaces to accumulate chips in the cut, see figure 12. Fallen sticks and debris or sticks and debris sliding across the saw blade can enter these gaps when the blade is rotating and be struck by the teeth and be tossed or thrown. Larger gaps and lower rotation speeds increase these dangers.

COMMENTS AND INSTRUCTIONS CONTINUED SAW HOUSING ENTRANCE AND EXIT SPACE To avoid the ingestion of materials into the housing space above the disc (and later ejection) the ingoing entrance for the saw rim of teeth is kept as small as practical. It is important that this high wear area be maintained at its original size and shape. The outgoing opening is large enough to allow the housing to clean itself and will allow most things inside to be thrown out, see figure 13. Its throw direction and angle must be respected. A long snout on the other side reduces this danger.

Using High-Speed Disc Saws Safely

This information is offered by Tigercat as part of interim action to make saw heads safer. It is based on what has recently been reported from the field and on tests conducted on proving grounds. Tigercat is continuing to do design and testing of tree felling machinery towards achieving greater safety in the woods. Tigercat would be thankful for written reports describing any unsafe happenings, including near misses, in the use of felling heads and their carriers.

THE FOLLOWING ARE SOME SAW HEAD DON’TS THAT APPLY PARTICULARLY TO THROW PREVENTION: • Do not point the throw of a disc saw head in a direction towards people, vehicles or buildings at any visible distance.

• Do not operate in a way that throws chips in a direct-line at the machine cab.

• Do not push hard with the saw against anything except a standing tree to be cut.

• Do not mix new sharp teeth with old dull teeth on the same saw.

• Do not change the blade rotation from its designed direction in the head.

• Do not over speed the blade rpm.

• Do not remove or shorten snouts provided by the head manufacturer or installer.

• Do not neglect tooth fastening inspection, maintenance and replacement.

• Do not neglect to repair worn or damaged saw housings.

• Do not neglect to replace any covers removed for service or clean out.

• Do not count on skis to give the throw protection that snouts do.

• Do not nudge loose short pieces with the front of any type of head.

• Do not nudge anything, even long logs, with the front of a head which has no snouts.

• Do not cut short small stalks when blade speed is low.

• Do not operate a high speed disc saw in a populated area.

• Do not assume that visitors and other workers are aware of disc saw dangers.

• Do not assume that the operator will spare you, a visitor, from danger.

• Do not select and operate heads that throw rearward.

• Do not select and operate heads with unnecessarily wide throw angles.

• Do not neglect to read and follow all instructions provided by the saw and head manufacturers.

Speed Control Lever

The speed control lever allows the operator to set the maximum speed of the machine to maintain a given speed without having to feather the drive pedals. The speed control lever is mounted on the left arm rest, below and to the left of the steering joystick.

Push the lever forward to increase the maximum speed.

Pull the lever back to decrease the maximum speed of the machine. When the lever is pulled fully back the machine will be in creep mode. This applies only to machines equipped with WideRange.

Gear Shift Lever

Shifting gears must be done while the machine is stopped (stationary). The two-speed transmission does not have the capability to mesh moving gears. If the operator shifts gears while the machine is in motion, severe damage will occur to the shift collar and its mating gears and will result in a difficulty or inability to shift from one speed to the other. In order to shift gears with minimum effort and without damaging the transmission, there must be no motion between the gear teeth of the shift collar and the teeth of the low or high speed gear.

Shifting Procedure: • Bring the machine to a full stop on level ground.

• Reduce the engine speed to idle.

• Depress foot break pedal to hold the machine stationary.

Creep mode provides maximum available tractive force to the wheels at a reduced speed.

• Move the gear shift lever (push or pull) to engage the desired gear.

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

NOTE: If the gear will not engage, the shifting collar and the speed gear have not aligned.

NOTE: Machines equipped with dual motor single speed transmissions are equipped with a creep switch. It is important to note that the speed control lever will not operate when the creep switch is in the ON position.

This can be corrected by lightly touching the steering joystick to slightly articulate the machine, which will aid the collar and gear to mesh and allow for easy shifting.

Controls and Operation

Tigercat 724E Feller Buncher

PROBLEMS AND CORRECTIVE ACTION • Rides is too stiff/Seat tends to push or throw operator forward The ride adjustment knob has been tightened (turned counter-clockwise) too much. This typically happens because the operator is trying to use additional ride adjustment knob rather than the height adjustment lever to raise the seat. Operator is riding the seat in the low height position setting.

Refer to HEIGHT ADJUSTMENT. • Rides is too soft or bottoms out and pinches operator The seat ride adjustment knob has not been tightened (turned counter-clockwise) enough.

Insufficient ride adjustment exaggerates the kneeaction movement of the seat. This usually happens because the operator is trying to lower the seat by decreasing the amount of ride adjustment instead of using the height adjustment lever. Refer to HEIGHT ADJUSTMENT. • Seat is too high/Seat too low There are several things which can cause improper seat height. Refer to the height adjustment and adjust seat to the desired position. If the proper height cannot be reached using one of the four height adjustment settings, it may be necessary to install the seat on a higher base.

• Operator’s legs falling asleep The seat is adjusted too high, and the ride adjustment knob has not been tightened (turned counter-clockwise) enough, resulting in the operator sitting in a bucket. Refer to HEIGHT ADJUSTMENT and RIDE ADJUSTMENT.

Attachment Indicator

Consider the four gauge increments as ¼, ½, ¾ and 1.

During cutting operations the indicator value will rise to 1 as the blade slows down due to cutting, and fall as the blade speeds up. A ¾ value or higher indicates that the blade has not attained full speed from the previous cut or has jammed.

2.22

Tigercat 724E Feller Buncher

Controls and Operation

IMPORTANT! Once the pilot interlock system has been activated, the safety of both the operator and all persons outside the cab becomes the responsibility of the operator.

When the switch is in the auto position and the fan has stopped due to low charge air, engine coolant or hydraulic oil temperatures, turning ON the A/C will cause the fan control to immediately turn the cooling fan to run at 1200 rpm when the engine is at 2200 rpm. This is to ensure that sufficient air flow is available for the cab A/C even while the machine is still warming up.

IMPORTANT! The door interlock switches and the PILOT RESET switch are safety features and their function must not be defeated in any way.

FULL ON (OVERRIDE) POSITION\ When the switch is in the FULL ON (override) position, the fan control system is overridden and the fan will run at full speed for cooling regardless of charge air, coolant or oil temperatures. Normally the fan control switch is placed in the auto position for optimal cooling. The FULL ON (override) position is intended for use in the event of a temporary failure of the fan control. Auto reversing/ cleaning does not function in FULL ON position.

FAN, SWITCH (J)

This is a three-position switch, labelled CLEAN/AUTO/ FULL ON*. This switch along with an electronic fan control module, controls the operation of the hydraulic cross-flow fan.

CLEAN POSITION When the switch is depressed momentarily in the clean position, the direction of rotation is reversed. Reverse rotation is used to clean the charge air cooler, radiator, oil cooler, A/C condenser and air intake door screens. By reversing the flow of the fan, air flow is propelled in the opposite direction, thereby forcing dust and debris off of the cooling assembly.

BULB TEST SWITCH (K)

This momentary switch is used to perform a bulb and audio alarm buzzer test. Hold this switch in the ON position to test all warning lights on the instrument panel.

Replace burnt out lights immediately to ensure that all warning lights are in working order at all times.

The electronic fan control will also turn the A/C system OFF for as long as the fan switch is in the clean position.

IGNITION KEY SWITCH (L)

This is a three-position switch labelled OFF/RUN/START.

The fan auto reversing function is factory set to cycle every 10 minutes.

• OFF Position – All electrical power fed through the key switch is turned OFF.

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

• RUN Position – Connects the battery to all functions.

Used for normal machine operation.

• START Position – Used to energize the starter motor to start the engine.

AUTO POSITION This is the normal operating position for the fan control switch. When the switch is in the auto position, the fan will operate completely in an automatic mode. It will start, speed up, slow down or stop all based on the temperature of the charge air, engine coolant and/or the temperature of the hydraulic oil. The electronic fan control module automatically adjusts fan speed to the minimum required level to maintain optimal operating conditions, provides auto-reversing and default to the fan at full speed if an error in the controller exists.

Automatic control of fan speed to match operating conditions can lower fuel consumption and reduce operating costs. In high temperature operating conditions the fan speed is increased to improve cooling ability and efficient operation of the charge air cooler, radiator,oil cooler, and air conditioning systems. In low temperature operating conditions fan speed is reduced, as less cooling is required.

NOTE: The parking brake must be engaged to turn ON the engine.

PARKING BRAKE SWITCH AND LIGHT (M)

7241001–7241020 AND 7241101–7243000 The parking brake is spring applied and hydraulically released. The parking brake is engaged (light ON) when the switch is activated to turn the brake ON, or the ignition key is turned OFF, or the cab door is opened when the engine is running.

To disengage the parking brake, close the cab door, start the engine and depress the pilot reset and parking brake switches. The light will turn OFF and the brake will disengage.

NOTE: Stop machine travel before opening the cab door. Whenever the cab door is opened the parking brake will engage.

The A/C condenser core is located on the left side of the machine and is mounted directly in front of the cooler package. The cross-flow fan is mounted on the right side of the machine. The cross-flow fan draws air from the left side of the machine through the door screen, the A/C condenser and the cooler package, blowing it out of the right side of the machine.

The A/C condenser core and cooler package should be manually checked every 8 hours (every shift) or more often where conditions cause accumulation of twigs, leaves, pine needles and dust. All of the engine enclosure doors should also be checked.

This cooling assembly (hydraulic oil cooler (C), the radiator (D) and the charge air cooler (E)) must be checked daily and may require thorough cleaning on a regular basis depending on operating conditions.

Compressed air or water may be used for cleaning. Use personal protective equipment to guard against flying debris.

If an oil leak occurs in this area it should be thoroughly power-washed with a mild soap to ensure that all of the oil is removed. The presence of oil causes dust and dirt to cling to surfaces which will impair the reversible fan's ability to remove dust and dirt particles.

Care must be taken when cleaning this assembly, as the components can be damaged by careless handling and cleaning.

CARE OF POLYCARBONATE WINDOWS IN CAB (WINDSHIELD, SKYLIGHT AND THREE REAR WINDOWS)

• Cracks, chips, notches or scarring anywhere on the viewing surface 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.

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.

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

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.

• 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.

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. Windows with defects must be replaced immediately.

INSPECTION AND MAINTENANCE

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

• 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

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

• Inspect all windows daily and immediately after any impacts.

Other chemicals however can seriously weaken the polycarbonate.

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

Do not permit any of the following chemicals to come into contact with polycarbonate windows:

• 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.

• Acetone

• 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 its ability to resist heavy impacts and therefore compromise effectiveness as operator safety protective equipment. Windows with these defects must be replaced immediately.

• Brake fluid

• Air conditioning refrigerant • Ammonia • Anti-freeze • Benzene • Carbon tetrachloride • Cutting oils • Gasoline • Lacquer thinner • Toluene • Turpentine • Xylene

Tigercat 724E Feller Buncher

RESISTANCE TO WATER

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.

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.

• Do not clean polycarbonate windows when the daytime temperature is high or in direct sunlight.

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.

• Do not use abrasive or highly alkaline cleaners on polycarbonate windows.

CLEANING INSTRUCTIONS

• Do not use glass cleaners in either aerosol or nonaerosol containers to clean polycarbonate windows.

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

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

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

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.

CONCEALING HAIRLINE SCRATCHES

The appearance of scratches and minor abrasions on the surfaces of polycarbonate windows can be minimized by using a mild automotive polish such as: • Johnson’s Paste Wax

Brand name soaps and detergents recommended for cleaning polycarbonate are: • Fantastik

• Novus Plastic Polish #1 and #2 • Mirror Glaze Plastic Polish

• Hexcel F.O. 554

Be certain to clean the polycarbonate window as outlined prior to application of an automotive polish.

Refer to CLEANING INSTRUCTIONS.

• Joy

GRAFFITI REMOVAL

• Formula 409

• 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.

• Lysol • Mr. Clean • Neleco-Placer

• 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.

• 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 through 4.

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

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.

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

The machine may be transported with the wheels on or 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 felling head must be lowered to the truck bed.

• The articulation lock bar must be installed.

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

IMPORTANT! Use only transport regulation chains for this purpose, example; 5/16" grade 7 with a tensile strength of 40,800 kg (96,000 lbs)/chain. Using inferior or damaged chains could cause the load to shift.

The machine must be crossed chained (side-to-side) at both the front and rear axle area.

The chains may be looped around the axles and hooked onto the links of the chain creating a full loop around the axles. The chains should be attached to the opposite sides of the trailer and evenly tensioned with the load binders.

There will be no charge for the first oil samples required to be taken during the 100-Hour Inspection Service that will be scheduled and performed by your Tigercat dealer. Refer to NEW MACHINE MAINTENANCE in THIS SECTION.

FOLLOW-UP SAMPLES

All follow-up samples must be taken as indicated in the chart above and will be the responsibility of the machine owner.

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

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

Lubrication and Maintenance

TIGERCAT OIL SAMPLE COLLECTION 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.

A

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.

B

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.

Oil Sampling Connector Hydraulic Oil Return Filters

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.

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

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

• To obtain a representative oil sample, the sample valves must be purged before the actual oil sample is taken. Drain a minimum of 89–118 ml (3–4 oz) of oil into a separate container and discard this oil using approved recycling methods.

• 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.

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

TRANSMISSION, AXLES AND PUMP DRIVE GEARBOX SAMPLES:

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

• These samples can be taken during the oil change process.

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

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

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

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

GENERAL • 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.

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

• Clean around filler caps before checking or adding fluids.

• Before welding on the machine be sure master switch is disconnected and disconnect the multi-pin connectors on the engine CPU and the engine wiring harness.

• Release hydraulic pressures and clean around hydraulic fittings before breaking connection. Plug or cap immediately.

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

• Clean up spills as soon as possible.

• Always use clean hydraulic oil and filters.

• Drain dirty oil while still warm.

• Do not exceed recommended fluid levels.

• Clean away all branches, bark and chips. Clean up all traces of oil to avoid fires.

• Service all hydraulic diffusers and 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. For safety, always lower the boom assembly to the ground when leaving the cab, leaving the machine unattended or during service.

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

• For safety, when working under the boom, always lower the boom to the ground, support the boom properly or install the lift boom cylinder lock. Refer to SECTION 2 of THIS MANUAL.

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

• 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.

CHECK EMERGENCY EXITS (MONTHLY)

Two alternate exit routes are provided: right cab door and the skylight / emergency exit. These are only to be used if the left cab door cannot be opened.

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

CHECK FIRE EXTINGUISHER (DAILY)

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.

A

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 could have re-positioned itself onto the engine and exhaust parts due to wind turbulence caused by the journey.

• Forest debris and fine organic material (twigs, pine needles, branches, bark, leaves, saw dust, small wood chips) and any other combustible materials, 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.

A

• 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.

Charge Gauge

• If equipped, read the FIRE SUPPRESSION SYSTEM MANUAL and have the system serviced regularly by qualified personnel.

A portable fire extinguisher is located in the operator's cab. The extinguisher should be checked daily to ensure that it is charged. The pointer on the charge gauge should point to the green region. If the indicator falls out of this green area, the extinguisher should be serviced immediately.

• 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 of THIS MANUAL for additional information.

Maintain a charged fire extinguisher on the machine at all times and know how to use it.

Refer to the extinguisher MANUFACTURER’S USE AND INFORMATION MANUAL for proper usage, additional information and recommended inspection and maintenance intervals.

Lubrication and Maintenance FILTERS, REMOVE AND REPLACE

Tigercat 724E Feller Buncher PRIMING THE FUEL SYSTEM

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 catalogue for replacement filters.

B

FUEL FILTER/WATER SEPARATOR

Two fuel filters are supplied with the engine. Refer to the ENGINE MANUFACTURER'S OPERATION AND MAINTENANCE MANUAL for service information and replacement interval.

A

IMPORTANT! Filters that are an integral part of the engine (fuel and lubricating oil) should be serviced and replaced according to the ENGINE MANUFACTURER'S OPERATION AND MAINTENANCE MANUAL. Tigercat generally does not recommend the pre-filling of fuel 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 system. Contaminants in unfiltered fuel can cause significant and costly damage to the engine. The cleanliness of fuel cannot be guaranteed unless it is always pre-filtered before use.

724E-027

A B

Fuel Filter Fuel Filter/Water Separator

Whenever the fuel system has been drained, disconnected or the fuel filters have been replaced, the fuel system must be primed to remove any air from the system.

1. Turn the ignition key to the ON position to activate the fuel shut-off valve.

2. Open the primer (hand) pump on the fuel filter/water separator and pump fuel into the filters until fuel begins to seep out of the vent on the primer pump shaft.

3. Close the primer pump and wipe up any spilled fuel.

4. Refer to the ENGINE MANUFACTURES OPERATION MANUAL for more information on priming the fuel system.

3.22

Tigercat 724E Feller Buncher IMPORTANT! If the fuel supply is dirty, the fuel filter must be replaced more frequently than recommended in the ENGINE MANUFACTURES OPERATION MANUAL. Operating the machine with a clogged fuel filter will result in low engine power. It is also recommended that the fuel/water separator bowl be drained daily.

When installing a new fuel filter, do not pre-fill with diesel fuel, or engine fuel pump damage will result. This type of failure is not warrantable by the engine manufacturer.

To prolong the operating life of the fuel filter, ensure that the fuel supply storage tank is clean and free of water and that the fuel is pre-filtered prior to adding it to the machine.

Lubrication and Maintenance FUEL TANK STRAINER

This is a stainless steel fuel strainer, screwed on to the end of the inlet pipe of the engine fuel feed line inside the bottom of the fuel tank.

CHANGING OR CLEANING THE STRAINER:

NOTE: This should only be required if excessive quantities of foreign material has built up inside the tank.

1. Park the machine on level ground with the attachment resting firmly on the ground.

2. Apply the parking brake.

3. Turn OFF the engine.

4. Remove the ignition key.

5. Turn OFF the battery disconnect switch.

6. Install the articulation lock bar and block the wheels.

7. Drain the fuel tank (plug in bottom).

8. Remove the round fuel tank cleanout cover plate and O-ring from the access hole.

9. Before removing the strainer, clean any debris from the bottom of the tank and wipe it clean.

10. Remove the fuel strainer using the hex on the end of strainer. Carefully clean the strainer (it may be damaged by rough handling).

11. Check for a buildup of foreign materials where the strainer threads on to the pipe and elbow.

12. Reinstall the strainer using the hex on end.

13. Reinstall the fuel tank cover plate with O-ring.

20. Fill the hydraulic tank up to the FULL mark on the sight gauge using the fill pump.

NOTE: Changing diffusers and filters and replacing the hydraulic oil tends to aerate the oil. For maximum pump life, the machine should sit for one hour after servicing to allow any air bubbles to escape from the oil prior to applying working pressures to the pumps.

HYDROSTATIC CHARGE PUMP PRESSURE AND PILOT/CASE DRAIN FILTERS

HYDRAULIC FILTER SERVICING GUIDELINES IMPORTANT! NEVER PRE-FILL HYDRAULIC FILTERS. Tigercat generally does not recommend the pre-filling of spin-on filters due to the risk of damage to the hydraulic system caused by unfiltered oil. Unfiltered oil used to pre-fill filters enters directly into the hydraulic circuit.

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

Warning, HOT FLUIDS and hot machine surfaces can cause serious burns!

1. Park the machine on level ground with the attachment resting firmly on the ground.

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

2. Apply the parking brake.

3. Turn OFF the engine.

4. Remove the ignition key.

• Use a thermometer to check surface and system temperatures to ensure it is safe to begin service work.

5. Turn OFF the battery disconnect switch.

6. Install the articulation lock bar and block the wheels.

• DO NOT begin service work until the surface or system temperature has cooled down to below 38°C (100°F)!

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

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

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

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

11. The new filter has an attached gasket. Apply hydraulic oil to the gasket surface.

Important Steps To Follow When Changing Filter Elements: • Remove the cover/dust bowl from the air cleaner assembly.

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

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

B

• Always clean the inside of the outlet tube.

• Check your old filter sealing surfaces. This will 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.

• Inspect the new filter for damage.

INTAKE TUBING AND JOINTS

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 air cleaner. This should be green when the engine is running at full RPM. Service is required only if the indicator is red (yellow indicator light on the instrument panel is ON and the horn sounds on 7241601–7242000).

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

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

Lubrication and Maintenance 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 may actually be 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 hydraulic oil or diesel engine oil filters.

• Servicing Engine exposure to dust during servicing is a large reason for engine damage due to dust. Abrasive dust can easily enter the intake system once the air cleaner cover and protective filter element are removed for replacement. The safety element does reduce this risk but it should also be replaced at every third primary element change.

IMPORTANT STEPS TO FOLLOW WHEN CHANGING FILTER ELEMENTS

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

2. Gently pull the element out of the housing to avoid dislodging dust from the filter element(s).

3. Check your old filter sealing surfaces. This will help detect foreign material on the sealing surface that is causing leakage.

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

4. Always clean the inside of the housing.

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

6. Inspect the new filter for damage.

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

Air Charge Valve Pressure Gauge

The pressure gauge (B) on the side of the seat should read 4.14 bar (60 psi).

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 4.1 bar (60psi) the system needs to be purged. Refer to PURGING PRESSURIZED WATER SYSTEM in THIS SECTION. After testing, the tank must be refilled and pressurized (A) to 4.1 bar (60 psi). Refer to the following the FILL AND CHARGE procedure (to be carried out yearly).

3.34

Tigercat 724E Feller Buncher FILL AND CHARGE PRESSURIZED WATER SYSTEM

1. Completely discharge all water and compressed air from the tank via the hose end nozzle.

CAUTION Never remove the fill plug before de-pressurizing the 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 the fill plug two full turns. Any remaining air in the tank will be heard expelling from the special fill plug. Do not remove the fill plug until all the air has been expelled.

Lubrication and Maintenance PURGING PRESSURIZED WATER SYSTEM

Purging should be carried out whenever the flow of water does not forcefully discharge from the end of the hose with the pressure gauge reading 4.1 bar (60 psi).

1. Follow procedures (1) and (2) from FILL AND CHARGE PRESSURIZED WATER SYSTEM. 2. Close the water shut-off valve and add 7.6 L (2 US gal) of clean water to the tank. Reinstall the fill plug and charge the system with 4.1 bar (60 psi) of compressed air through the charging valve.

3. Open the shut-off valve and completely discharge all the water in the tank via the hose end nozzle.

4. If a forceful discharge was not achieved, repeat the purging procedure. If a second purging does not work, remove lines and check for an obstruction.

5. After the purging operation, fill and charge the system as described in FILL AND CHARGE PRESSURIZED WATER SYSTEM in THIS SECTION.

3. Close the water shut-off valve and fill the tank with water. Tank capacity is approximately 16 L (4.2 US gals).

NOTE: When temperatures below 0°C (32°F) are anticipated, add a non-toxic RV antifreeze or other suitable antifreeze solution to the water (50% water, 50% RV antifreeze).

NOTE: Most non-toxic RV antifreeze solutions contain corrosion and algae inhibitors, it is therefore suggested that this solution be added to the water on a continual basis regardless of temperature conditions.

4. Install the fill plug in the tank.

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

4. Close the cab doors, turn the ignition key switch to the 'ON' position and depress the pilot reset switch.

This allows pilot oil to circulate and refill the pilot and case drain circuits during the following cranking procedure.

5. Crank the engine for five seconds, then wait for five seconds. Check the charge pressure gauge during cranking to observe for pressure reading. Repeat five times to pump oil into the pumps and the system components.

NOTE: If the charge pressure gauge does not indicate a rise in pressure, check for possible cause (air in system, leaks, loose hose fittings, pumps not turning, etc.). Repair the problem. Repeat Step 5 until a rise in charge pressure is noticed.

6. Reconnect the engine wiring harness multi-pin connectors.

7. Turn ON the engine. If the charge pressure does not rise within 20–30 seconds, turn OFF the engine.

If the charge pressure is between 18–31 bar (260–450 psi), run the engine at idle for 20 minutes.

Check the engine oil pressure in the cab. Do not operate any functions.

8. With the engine at idle, the parking brake ON (engaged), hold the foot brake down, bleed the brakes in rear axle.

MIDDLE DRIVE SHAFT SPLINE LUBRICATION

FRONT AND REAR SLIP SPLINE LUBRICATION

When operating in extremely wet or dusty conditions or when the regular service schedule has been neglected, insufficient lubrication to the spline area of the middle drive shaft will result in premature wear. In addition, old grease often forms into a semi-solid, rubber-like plug preventing the purging of contaminants (water, dirt, sand, etc.) through the slip spline seal.

A

The most common cause of joint and slip spline failure is lack of proper lubrication.

Lubrication and Maintenance The temperature sensor in the hydraulic tank operates in a similar manner to the engine coolant temperature sensor but independently and with a different temperature range. Refer to the COOLING SET POINTS table.

This sensor will signal the electronic control module to turn the fan ON at the appropriate temperature. Refer to the COOLING SET POINTS table. As the temperature of the hydraulic oil increases, the speed of the fan will also increase to a maximum 2200 rpm fan speed @2200 rpm engine speed. At this point the temperature of the hydraulic oil will be (refer to COOLING SET POINTS table), or higher.

When the switch is in the auto position, and the fan is stopped due to low engine coolant, air intake or hydraulic oil temperatures, turning ON the A/C will immediately turn the cooling fan to run at 1200 rpm. This is to ensure that sufficient air flow is available for the cab A/C even while the machine is still warming up.

CAUTION Before placing the fan switch in the CLEAN (PURGE) position, make sure there are no personnel on the left side of the machine in the area where the fan will expel debris.

Fan Switch

When the engine coolant temperature reaches 85°C (185°F) the sensor on the engine, in conjunction with the electronic control module, sends a signal to the control valve to start to turn the fan slowly. The fan speed is variable from zero, up to a maximum of 2200 rpm fan speed @2200 rpm engine speed. As the temperature of the coolant increases, so does the speed of the fan, up to the maximum 2200 rpm fan speed @2200 rpm engine speed. At this point the engine coolant temperature will be 96°C (205°F), or higher.

When the switch is in the FULL ON (override) position, the fan will run at full speed for cooling, regardless of coolant, air intake or oil temperatures. The auto clean/ reverse feature will not function in the FULL ON position.

When the switch is pressed momentarily to the clean (purge) position, the control module will signal the control valve to reverse the flow of oil to the motor and turn the fan in reverse. The control module will also turn the air conditioning system OFF for as long as the fan switch is in the clean (purge) position.

Assembly Torque

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

WASHERS BOLTS FLANGE CLAMP

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.

Flange Port Assembly The steps to properly assemble the flange port clamping bolts are:

FLANGE HEAD

1. Make sure sealing surfaces are free of burrs, nicks, scratches or any foreign particles.

O-RING

2. Lubricate the O-ring.

TAPPED HOLES

3. Position flange and clamp halves.

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

5. Hand tighten bolts.
