Introduction

This operator enclosure meets the following standards: oregon osha 437-007-0775:14a tip-OVER PROTECTION STRUCTURES (tOPS) iso 8084: 1993 OPERATOR PROTECTION STRUCTURES (OPS) iso 8083: 1989 FALLING OBJECTS PROTECTION STRUCTURES (FOPS) iso 3411: 1995 iso 2867: 1994 sae j1356: feb 1988 oregon osha 437-007-0775:14b,c AS 4988: 2002 * MODIFICATIONS AND REPAIRS: The integrity of the TOPS, 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 TOPS, FOPS, OPS structure will become void if any such modifications take place.

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

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

ii) Approved modifications officially released by Tigercat.

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

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

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

Operator's cabs are designed to TOPS, FOPS, OPS standards so that they will withstand force and absorb energy during a tip-over (TOPS), 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 TOPS, 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 tip-over protective structures.

GENERAL SAFETY PRECAUTIONS continued

Check all fluid levels.

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

WARNING Do not walk on machine surfaces with steel cleated foot wear. Steel cleats on steel surfaces are slippery and do not provide a safe foot hold.

WARNING It is not recommended to walk on machine surfaces that are not designated walking areas.

No attempt should be made to walk on angled steel surfaces or surfaces that are irregular in shape.

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

Walking surfaces on the machine must be covered with anti-slip materials to provide a safe foot hold and prevent slipping.

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

These anti-slip surfaces should be maintained on a regular basis. If the surface shows signs of wear, the anti-slip material must be replaced immediately.

Some advice which should be observed: •

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

• • •

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

• •

Machine should be washed completely at every major service.

•

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

Tigercat H855C/LH855C Harvester

Safety 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.

GENERAL SAFETY PRECAUTIONS continued 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).

Maintain a distance of 3m (10 ft. ) between the machine or boom and any power line carrying up to 50,000 volts or less plus 10mm (1/2 inch) for each addition 1,000 volts above the 50,000 volt level.

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

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

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

If the machine must be transported, make sure that it is adequately secured to the transporting vehicle. Refer to vehicle moving instructions page in SECTION 2.

Visually inspect any seals or gaskets which have suffered from heat; they will appear black and sticky.

•

If these are found, Do Not Touch!!!

•

Determine the material composition of any seals or gaskets, If fluoro-elastomer seals (Viton, fluorel, or tecmoflon) have been used, the affected area must be decontaminated before undertaking further work. Natural rubber and nitrile materials are not hazardous.

•

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

•

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

Stopping the engine immediately after it has been working under load can result in overheating and premature wear of the engine components.

Reduce engine speed to LOW IDLE and let run for approximately 5 minutes to allow gradual dissipation of heat and also to reduce turbo speed. This will also prevent loss of coolant by after boil and possible hot spot damage to the engine.

Be aware when performing service and maintenance tasks that surfaces and grab handles in and around

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

the engine and cooling system may become very hot when the engine has been running. Contact with hot surfaces may cause injury.

Safety Hazards - Operating Maintain a charged fire extinguisher on the vehicle at all times and KNOW HOW TO USE IT.

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

Do not attempt to operate this machine on slopes without first receiving proper training.

•

Learn the stability limits or “feel” of the machine by first working on gentle slopes and by positioning the boom to reduce the risk of tipping. Gain experience over time by gradually increasing the angle of the slopes on which you are working.

•

Keep the attachment as close to the ground as possible to increase machine stability, and to allow the boom to be quickly lowered to the ground should the machine begin to tip.

•

Always use the LOW speed setting for the track drives when on slopes.

Travelling at an angle to the slope other than straight up and down decreases the traction of the tracks. Increasing the angle to the slope away from straight up and down can cause the machine to slide sideways downhill and/or possibly tip over.

•

Never travel across a STEEP slope or side hill.

Always carry any load on the uphill side of the machine.

Do not lift or move objects that exceed machine stability.

Always be prepared to release the load in case it causes the machine to tip.

Always position the cab so that you have a clear view in the direction of travel. Be aware of ground conditions and obstacles in the machine’s path before moving the machine.

When crossing obstacles (boulders, stumps, ditches etc.) the machine can shift rapidly, greatly affecting the stability of the machine. Move slowly over obstacles, and position the boom against the ground to reduce the risk of the machine shifting rapidly.

Backing over obstacles unexpectedly while traveling down a slope poses a tipping risk. Know the path of the tracks whenever the machine is moved.

When climbing a slope the boom should face uphill and the attachment should be kept close to the ground (FIG. 3). When descending a slope the boom should face down hill and the attachment should be kept close to the ground (FIG.4). Be aware that the machine is in its least stable position on a slope with the boom to the rear (see also FIG.1). Be particularly aware of machine stability when changing directions on, or travelling back down a slope.

As you gain experience, recognize that the maximum slope on which the machine can operate cannot be defined simply by an angle value. Variables in surface terrain, soil types, rocks, boulders, stumps, and fallen trees, changing weather conditions, and first and foremost the operator’s experience and skill levels greatly affect the maximum slope limitations. Be aware that these factors can result in a shallow slope posing greater risk than a relatively steeper slope. DO NOT attempt to work on slopes beyond your personal capability level.

•

Increases operator visibility, permitting better placement of the head on the tree and improving awareness of saw bar location and penetration, tree species and areas of rot, splits and crooks.

•

Reduces the potential for damage to both the standing trees and the harvesting head and stick boom components.

•

Improves the stability of a machine working on uneven ground as the weight of the boom, head and tree need not be extended as far out in front of the machine.

•

Broadens the working area that can be reached by the boom and thereby lessens the need to reposition the machine as frequently during harvesting operations.

FIGure 2. HARVESTER HEAD SWINGING

Tigercat H855C/LH855C Harvester

Safety Should contact between the harvesting head and the cab occur at any time during the operation of the machine, the following procedure must be completed.

OPERATING SAFETY PRECAUTIONS continued However operators of these machines are advised that working with the harvesting head in close to the machine also increases the chances of the harvesting head making contact with the front area of the cab, particularly if the head is swinging backwards as it dangles from the end of the stick boom. See both the upper and lower sections of Figure 2.

1. Inspect the cab, the front door and the front window immediately to determine if any damage has occurred.

2. Be certain to read, understand and follow the sections in this Operator’s Manual titled “CARE OF POLYCARBONATE WINDOWS IN CAB” and “INSPECTION AND MAINTENANCE”.

For all machines equipped with a harvesting head, the following procedures must be followed during the operation of the machine to avoid contact of the harvesting head with the cab.

1. When nearing the boom positions shown in Figure 1: •

Always keep the head in the upright harvesting position.

•

Do not tilt the head from the harvesting to the processing position as the saw housing may contact the cab.

•

Reduce the speed of boom movement.

Rapid movement could cause the base of the harvesting head to swing backwards towards the cab.

•

Avoid any sudden movements with the track drive system as this could cause the head to swing backwards into the cab.

2. Never bring the harvesting head in close to the machine while the harvesting head is swinging on the end of the stick boom. See Figure 2.

3. Do not use the head to pull downed trees directly towards the cab. If the clamping arms slip on the tree, the head may quickly swing towards the cab.

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

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

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.

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

• Seek professional medical attention immediately.

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

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

Always wear thick protective gloves.

• Be sure to wear safety goggles for eye protection.

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

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

Similarly fluid injected directly into a blood vessel can spread rapidly through your circulatory system. The human body has little ability to purge injected fluid.

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

•

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

Although fluid injection accidents are rare, the resulting injury has on occasion required the amputation of a finger, a hand or in some cases the entire limb. The longer the delay in getting professional medical aid, the further up the limb the tissue damage can spread.

An injury of this type can become very serious or even fatal if not dealt with promptly and properly.

1.26

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

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

When performing any service work • Stop the engine and relieve all diesel fuel or hydraulic pressure before disconnecting any lines or otherwise working on the system.

• Never grab any hydraulic or diesel fuel connectors or hoses when they are subjected to pressure.

• Always ensure that hoses are rated for the pressures to which they will be subjected.

• Never use any hoses that you suspect could be defective.

SERVICING SAFETY PRECAUTIONS continued GREASE INJECTION INJURY WHEN USING PNEUMATIC GREASE GUNS Pneumatic grease guns can deliver grease at pressures from 17 - 400 Bar (246 - 5801 psi). It takes less than 7 Bar (100 psi) to inject a substance through human skin.

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

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

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

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

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

•

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

•

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

•

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

•

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

•

Remove dirt and grease from grease fittings prior to greasing.

•

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

•

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

Safety LIGHTNING SAFETY

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

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

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

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.

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

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

1. Designate a member of your crew to

•

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.

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.

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

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

1.28

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

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

Tigercat H855C/LH855C Harvester

Safety What to do if you are outside and see lightning or hear thunder.

LIGHTNING SAFETY AWARENESS

If you can, get inside.

1. Run to the nearest building, motor vehicle or fully enclosed ROPS equipment cab immediately.

Being anywhere outside is not safe.

LIGHTNING SAFETY CONT'D Unfortunately loggers do not often work close to buildings and therefore other alternatives need to be considered.

2. If inside a building:

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

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

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

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

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

1.29

•

Don’t watch the lightning storm from open windows or doorways. Stay in inner rooms.

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

fire prevention

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

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

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

7. Steam clean the engine, hydraulic pumps, transmission, brake, fuel and hydraulic tank compartments and all 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.

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

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

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.

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.

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.

3. Blow off all forest debris and fine organic material accumulated near hot engine exhaust components (turbocharger and exhaust manifold as well as exhaust pipes and muffler) at the completion of each work shift or more frequently when working in logging conditions where large amounts of combustible forest debris are present.

Visual inspection after blow off to ensure thorough cleanliness is vital. Engine exhaust systems provide numerous small pockets where saw dust, small wood chips and other flammable forest debris can gather. Even small accumulations close to hot exhaust components can ignite and smolder. If dislodged this smoldering debris can fall into other areas of the machine and thereby spread a fire.

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

12. Never leave the machine parked with boom, arch or blade suspended off the ground.

Should their supporting hydraulic hoses burn through during a fire, pressurized hydraulic oil may be injected into the fire and the boom, arch or blade will fall rapidly to the ground.

1.31

Tigercat H855C/LH855C Harvester

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

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

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

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.

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 nonconductive such as CRC Contact Cleaner 2000.

10. TRACK, LOW/DRIVE - SWITCH WITH LIGHT

It should be noted that the available torque when travelling at maximum speed is only half of that in LOW.

This is a two position switch labelled LOW and DRIVE. IMPORTANT: This switch when in DRIVE provides infinitely variable travel speeds/torque ranges, unlike similar travel range controls on some types of construction equipment.

The DRIVE position will provide a faster travel speed range but with a lower driving force.

However, when the machine encounters tougher terrain conditions, e.g. stumps, soft ground or slopes etc., the drive system will automatically adjust* to a slower travel speed/ higher torque range.

LOW: Placing the switch in the LOW position will provide the slowest travel speed but with increased torque or driving force.

It is recommended that during all harvesting functions and when travelling on slopes that the range switch be placed in the LOW position to maximize drive motor life. Low position is indicated by a light on the Track Low/drive switch.

DRIVE: When this switch is in the DRIVE position the travel speed (and torque) ranges of the drive system become infinitely variable and will automatically adjust to any point between the HIGH and LOW speed/torque set points, relative to the terrain or load conditions.

2.31

*This amount of adjustment can be anywhere from a slight reduction in speed to all the way down to LOW, this will be dependant on the terrain conditions encountered.

NOTE: The operator should be aware that this automatic speed/torque range adjustment will cause the machine to gradually slow down over a period of 1 to 2 seconds, due in part to the infinitely variable displacement drive motors used. When travelling on relatively flat terrain it is not necessary to place the range switch in the LOW position .

11. HORN, SAFETY ALERT - SWITCH

13. COOLING FAN - SWITCH 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.

This is a two position “momentary” switch.

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

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

AUTO POSITION - AUTO 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 control module automatically adjusts fan speed to the minimum required level to maintain optimal operating conditions, and default to fan at full speed if an error in the controller exists.

12. SAW - SWITCH This is a two position switch labelled ON/OFF. On Harvester Model Machines this saw switch supplies power to the attachment’s control systems. A lockout button is incorporated into the switch to prevent the switch from being turned on accidentally. To turn the switch ON, push and hold the lockout button UP and place the switch in the ON position.

Place throttle in FULL position before turning attachment ON.

When the switch is in the AUTO position and the fan runs at minimum speed due to low charge air, engine coolant or hydraulic oil temperatures, turning ON the A/C will cause the fan control to increase the cooling fan speed when engine is at high idle. This is to ensure that sufficient air flow is available for the cab A/C even while the machine is still warming up.

NOTE: If the engine has been turned off or the pilot shut off system tripped (Front Door opened) with the saw switch left in the ON position, the attachment will not start up when the engine is restarted or the front door closed. In this case press the PILOT RESET button and turn the saw switch OFF and then ON.

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.

NOTE ALSO: The function of this switch may vary depending on the attachment model used and method of installation. Verify all functions before operating this machine.

15. CIGARETTE LIGHTER (24V) Cigar/Cigarette lighter (24 volt).

CLEAN POSITION - Momentarily pressing the switch to the CLEAN positon will start automatic reversing the direction of fan rotation (there is no need to hold the switch down). 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 radiator.

Note that the pilot system must be ON to operate the clean cycle.

The electronic fan control will also turn the A/C system OFF for as long as the fan is in the CLEAN mode.

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

Note: The CLEAN cycle also operates automatically via the timed purge function of the computer control system (frequency is adjustable). Refer also to COMPUTER ~ INFORMATION MESSAGES and COMPUTER ~DIAGNOSTIC ~ ADJUST FUNCTION PARAMETERS in THIS SECTION.

Tigercat H855C/LH855C Harvester

Controls and operation

DISCHARGE OF THE SYSTEM When an electrical signal (automatic or manual) is received by the control panel it sends a discharge signal to the electrical actuator located on top of the pressurized cylinder. When activated the electrical/pneumatic actuator extends a control shaft which mechanically opens the agent cylinder valve. This releases the dry chemical in the discharge area protected by the system.

At the same time the control panel will also automatically shut down the engine and all electrical power.

EARLIER STYLE

The automatic engine shutdown feature will either shutdown the engine immediately the fire suppression system is discharged (non levelling machines) OR will delay the shutdown for a period of between 10 to 15 seconds for levelling machines. The time delay period is a factory setting. This delay feature allows the operator to lower the load or move the machine to a safer location before the engine shuts down. The operator can extend the delay by pressing the SHUTDOWN RESET button on the control panel to repeat the preset delay period. This button can be pressed repeatedly until the operator has brought the machine to a safe stop. The SHUTDOWN RESET button does not delay the discharge of the fire suppression system.

LATER STYLE

The system will activate the discharge system and the automatic engine shutdown system. There will be a cloud of dry chemical dispersed in the discharge area. The engine will automatically shutdown either immediately or will be delayed for 10 to 15 seconds if the machine is a leveller.

IMPORTANT: Stop the engine before discharging the system. This will keep the dry chemical in the engine area.

Get away from the machine. Take the portable fire extinguisher in the cab or outside along if possible or obtain one from another location.

Stand by with a portable fire extinguisher and watch for any flashbacks after the system has discharged.

RED FIRE BUTTON

Do not restart the machine until it has been serviced and cleaned. Do not return the machine to service until the source of the fire has been located and neutralized. The fire suppression system must be recharged by Amerex Factory Certified Personnel before returning the machine to service.

AVOIDING DAMAGE AND FALSE DISCHARGES DURING MACHINE SERVICE:

860c-037

COMPONENT LOCATIONS

Pay attention to the location of the components of the fire suppression system. Take care not to damage heat sensors or wiring, this includes hitting, cutting, bending, denting, etc. Damage to heat sensors due to shock could cause an accidental discharge of the system. Cut, pinched, or kinked wiring could cause false signals and an accidental discharge of the system.

In addition thermostats are sensitive to heat from welding torches, steam cleaning or other outside sources which may create a false discharge of the system.

If any of the components are damaged, replace them immediately before operating the machine.

It is also important to take care around the chemical cylinder. The chemical cylinder is pressurized and can explode if struck with sufficient force. Pressurized cylinders are extremely hazardous.

WARNING Failure to follow the system manufacturers instructions and guidelines may result in serious bodily injury, death, and property damage.

B. ADJUST INPUTS

These settings (defined below) fine tune the operating speeds and start/stop ramps for the adjustable current out operated functions.

Adjustable inputs include: •

Proportional Telescopic (Voltage In) (if equipped)

MINIMUM CURRENT Minimum current settings control function start speed. Coils on hydraulic valves require a certain amount of current before they begin to operate the valve. The Min current value is the current that will be sent to the hydraulic valve coil when the function switch is activated.

VOLTAGE IN (VIN) The input signal at these inputs comes primarily from analog sensors, levers, and switches. These devices use a power/signal/ground system to provide an input value (VIN) between the high (+5V) and low (-5V) signals generated in the modules.

The min current is adjusted to a value that causes the function to just begin to move.

C. ADJUST OUTPUTS Adjustable outputs include:

MAXIMUM CURRENT Maximum current settings control the maximum speed the function will operate.

•

Right Level Cylinder (Current Out)

•

Left Level Cylinder (Current Out)

•

Pump 2 - Attachment (PWM Out or Current Out)

•

Controls and operation

PWM out (pwmout) PWM (Pulse Width Modulation) Out is a way of producing an analog signal level with a digital output that turns on and off many times a second. By varying the ratio between on and off time (modulation ratio or duty cycle) an output proportional to the system voltage can be obtained. PWMOUT maintains a constant output voltage, and the output current is governed by the resistance in the circuit.

630c-105

Press SELECT (F1) to select.

These settings (defined below) fine tune the operating speeds and start/stop ramps for the adjustable pwm out operated functions.

MINIMUM MR (modulation ratio) Minimum MR settings control function start speed. Coils on hydraulic valves require a certain MR before they begin to operate the valve. The Min MR value is the modulation ratio that will be sent to the hydraulic valve coil when the function switch is activated.

DISPLAY 3

The min MR is adjusted to a value that causes the function to just begin to move.

MAXIMUM MR (modulation ratio)

Use UP/DOWN scroll buttons to select the output you wish to adjust.

SYSTEM WARNING MESSAGES When system warning messages are displayed the master alarm may sound, see specific warning message descriptions for details. All system warning messages are logged and recorded by the IQAN system for use by Tigercat service technicians. Operator’s should respond to all warning messages immediately by bringing the machine to a safe stop and investigating the cause of the alarm.

The alarm can be acknowledged by pressing OK (F1), if applicable. Note that acknowledging the warning message does not address the cause of the alarm. Ignoring system warning messages may result in component damage and/ or subsequent malfunction. In addition ignoring system warning messages may also affect warranty claims. All warning messages should be addressed immediately to help ensure the efficient long term operation of the machine and avoid costly repairs.

822C-62

MODULE IS OFFLINE SYSTEM WARNING The MODULE IS OFFLINE warning message indicates a loss of communication with or power to an IQAN module. The offline module is identified on the display screen.

When a module goes offline all machine functions controlled by that module cease and all alarms and warnings associated with that module are triggered. If the problem is with the CAN wires all modules beyond the problem module will also be affected.

CAUTION Do not make adjustments in this menu.

Machine service indicators can be affected.

822C-75

NOTE: It is possible for an operator or service technician to disable this warning message. If the MODULE IS OFFLINE warning function is disabled for a module the first indication of a loss of communication or power to a module will be the loss of all machine functions controlled by the module and the triggering of all alarms and warnings associated with that module. This may cause problems in identifying the source of a control problem, as it will not be immediately obvious that a loss of communication or power to the module is the source of the problem.

To greatly reduce the time required to diagnose a MODULE IS OFFLINE warning, it is recommended that all available modules ALWAYS be set to ENABLED as shown. This screen is accessed through the INFORMATION MENU which should normally be accessed by Tigercat service technicians only.

LEVELLING ELECTRONIC ADJUSTMENT PROCEDURE

CHECKING LEVELLING SPEED (CYLINDER CYCLE TIMES)

Adjustments to the levelling system through the PROPERTIES MENU of the IQAN control system electronically adjust the performance of the levelling system to suit operating conditions . Refer also to COMPUTER ~ (PROPERTIES) MENU OPERATION in THIS SECTION.

1. Ensure hydraulic oil is at operating temperature.

2. Ensure no other personnel are in the area during this procedure. Start engine and set throttle speed to HIGH IDLE. 3. Close cab door and press PILOT RESET switch to activate pilot system.

Two types of adjustment can be made to the levelling system:

4. Place ANTI-STALL switch in the OFF position.

CYLINDER OPERATING SPEEDS Forward Level Speed and Rear Level Speed function parameter adjustments provide a means for setting the levelling FORWARD/ BACKWARD cylinder operating speed.

5. Press the REAR tilt levelling switch and fully retract BOTH cylinders.

6. Press the FORWARD tilt levelling switch and fully ** extend cylinders. Record cycle time from stop to stop.

CYLINDER TRACKING The Right Level Cylinder and Left Level Cylinder current out adjustments provide for setting the cylinder operation of both cylinders to prevent tracking (one cylinder extending or retracting faster then the other).

7. Operate the REAR tilt levelling switch and fully ** retract cylinders. Record cycle time from stop to stop.

These settings control the operation of the electrohydraulic spool actuators which control the cylinder tracking and operating speeds by regulating the flow of oil from the levelling control valve to the levelling cylinders.

8. If required, adjust the computer control system settings for forward levelling speed or rear levelling speed to achieve the time outlined in the chart (PROPERTIES ~FUNCTION PARAMETERS). Refer to adjusting FORWARD/REAR level speed in THIS SECTION for procedure.

NOTE: Adjustment of the FORWARD/ REAR speed is the setting required to obtain recommended cycle time. SIDE to SIDE speeds will be a product of these settings.

DANGER Extreme care and attention must be exercised when making adjustments to the levelling hydraulic and electrical circuits.

Ensure that all personnel not directly associated with the servicing are well clear of the machine.

The whole upper frame/cab/engine compartment, boom and attachment can tilt unexpectedly from side to side or forward and backwards during servicing, creating “pinch points” between the upper frame and track assembly and the ground.

NOTE ALSO: Some fine adjustments may be required to ensure that the upper frame does not track RIGHT or LEFT during the FORWARD/REAR movement. Refer to ADJUSTING CYLINDER TRACKING ~ ADJUSTING MAXIMUM/MINIMUM CURRENT for procedure. ** When extending or retracting cylinders to record the time, stop the cylinder just before it gets to the end of it’s stroke rather than let it bottom out and impose unnecessary loads on the cylinder parts and frame structures.

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.

Tigercat H855C/LH855C Harvester TRAVELLING (BOOM RAISED) 1. Select the appropriate drive range.

Place the track switch in the LOW or DRIVE position.

When in LOW the machine moves slower but with increased drive force. All harvesting should be done in LOW. When in DRIVE the machine moves faster but with less drive force. Travelling over longer distances (and not harvesting) should be done in DRIVE to allow for faster travel speeds when the terrain permits. Also, DO NOT travel continuously for longer than 10 minutes, take 5 minute breaks, this will help prevent the track drive gearboxes from over heating.

For a more detailed description of drive range refer to TRACK, LOW/DRIVE SWITCH in THIS SECTION. 2. Place swing brake switch in OFF position.

3. Move throttle control to the HIGH idle position.

4. Operate the drive foot pedals to manoeuvre the machine.

Controls and operation OPERATING TIPS WITH LOAD SENSING When using the controls on a load sensing system be aware of what the load sensing system is trying to do for you. If you move the lever or pedal 20% of its total angle, the system will provide whatever pressure it takes ( up to its maximum capacity if needed) to meet this speed requirement. If you move the lever past the point needed in an attempt to speed up the boom movement, you will only overshoot the speed you wanted. Relax and try to use the least amount of lever action you can.

Load sensing systems respond to rough operation by amplifying these movements. If you find the boom is jerky or always giving “feedback”, you’re probably too active on the controls. If slowing down doesn’t eliminate the roughness, the margin pressure setting may be too high and can be reduced to calm down the machine’s response.

ATTACHMENT OPERATING INSTRUCTIONS AND SAFETY PRECAUTIONS

SPECIAL OPERATING INSTRUCTIONS FOR ER BOOM SYSTEM (OPTIONAL)

1. All tree harvesting should be carried out in LOW driving range. Refer to TRACK, LOW/ DRIVE SWITCH in THIS SECTION.

NORMAL HORIZONTAL REACH MOTION PERFORMANCE CAN BE EXPECTED IN THIS AREA

2. Refer to HARVESTING ATTACHMENT GENERAL SAFETY in SECTION 1 of THIS MANUAL.

OPERATING THE MAIN BOOM IN THIS ZONE WITH A FULL LOAD WILL NOT ALLOW THE HORIZONTAL REACH MOTION TO PERFORM AS IT SHOULD WITHOUT ASSISTANCE FROM THE RIGHT JOYSTICK

3. Read and understand the operating and safety instructions found in the attachment manufacturer’s manual for the harvesting head installed on this machine.

H860C-034

HORIZONTAL REACH MOTION CHARACTERISTICS This ER boom system is designed to minimize heat generation and fuel consumption during horizontal boom motion. To obtain maximum benefit from the system, the machine should be operated using mainly horizontal reaching motions as much as possible, lifting and lowering the boom only as much as necessary for positioning until the head is full.

Due to the nature of this ER boom system, there will be certain conditions in which the weight of the head plus its carried load will be too great for the system to provide its intended horizontal reaching motion. This most notably occurs when the machine is operating on a hill with the head raised higher than the tracks and tucked in close to the cab. If such a situation occurs, the right joystick control should be pushed forward slightly while operating the left joystick to get the system moving. To help prevent this situation, the head should be kept as close to the ground as possible and slightly extended when climbing hills.

CARE OF POLYCARBONATE WINDOWS IN cab

•

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

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

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

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

RESISTANCE TO CHEMICALS 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.

Other chemicals however can seriously weaken the polycarbonate.

DO NOT permit any of the following chemicals to come into contact with polycarbonate windows: • acetone • air conditioning refrigerant • ammonia • anti-freeze • benzene • brake fluid • carbon tetrachloride • cutting oils • gasoline • lacquer thinner • toluene • turpentine • xylene RESISTANCE TO WATER Polycarbonate material has good resistance to water up to approximately 65°C (150°F). Above this temperature the effect of water is timetemperature related. This means that the higher the water temperature, the shorter the time before the polycarbonate is adversely affected.

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

Some windows used in the cab are made from a polycarbonate resin thermoplastic. This material is a replacement for glass when improved strength, durability and safety is required.

Polycarbonate material is expected to resist heavy impact and to absorb high levels of energy when contacted by high velocity thrown objects such as wood chips, cutter tools or stones.

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

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

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

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

• Inspect all windows daily and immediately after any impacts.

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

• The edges of the polycarbonate window must be evenly and fully supported on a flat surface around the entire window opening at all times.

Bent or dented skylight structures must be replaced immediately. Bent or dented cab structures must be evaluated immediately for possible repair or replacement.

• The edges of the polycarbonate window must be free from cracks, chips, notches or scarring and must not be pinched or stressed.

These defects will decrease ability to resist heavy impacts. Windows with these defects must be replaced immediately.

• Cracks, chips, notches or scarring anywhere on the viewing surface of the window will decrease ability to resist heavy impacts.

Windows with these defects must be replaced immediately.

CLEANING INSTRUCTIONS

CAUTIONS

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

•

DO NOT use abusive cleaning procedures either by hand or pressure washing on polycarbonate windows.

•

DO NOT use brushes, razor blades, scrapers, squeegees or other sharp tools on polycarbonate windows.

•

DO NOT clean polycarbonate windows when the daytime temperature is high or in direct sunlight.

•

DO NOT use abrasive or highly alkaline cleaners on polycarbonate windows.

•

DO NOT use glass cleaners in either aerosol or non-aerosol containers to clean polycarbonate windows.

•

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

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

1. Rinse the window thoroughly with lukewarm water 2. Using a soft cloth, cellulose sponge or chamois, gently wash the window with a mild solution of soap or detergent in lukewarm water. Do not scrub or use brushes or squeegees.

Brand name soaps and detergents recommended for cleaning polycarbonate are: • Fantastik • Formula 409 • Hexcel F.O. 554 • Joy • Lysol • Mr. Clean • Neleco-Placer • Pine-Sol • Top Job 3. Rinse the window thoroughly with lukewarm water.

4. Dry the window with a moist soft cloth, cellulose sponge or chamois to prevent water spotting.

5. To remove grease or oil, first rub lightly with a good grade of VM&P Naphtha or isopropyl alcohol followed by the same rinse, wash, rinse and dry procedure described in steps 1 to 4.

CONCEALING HAIRLINE SCRATCHES The appearance of scratches and minor abrasions on the surfaces of polycarbonate windows can be minimized by using a mild automotive polish such as: • • •

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

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

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

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

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

Detect problems early before they become major catastrophic failures.

•

Better ability to schedule downtime and forecast cost of repairs.

•

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

•

Increase used equipment value by providing proof of proper maintenance.

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

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

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

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

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

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

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

Contact your Tigercat Dealer Parts Department to order Kits.

Lubrication and Maintenance

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

HYDRAULIC SAMPLE VALVE

h855c-31

Hydraulic Oil Samples:

The accuracy of the lab analysis results is very dependent on the quality of the oil sample taken. Collection of clean oil samples that are representative of the main body of oil are essential if meaningful lab results are to be obtained.

Erroneous readings may result if proper collection, handling, packaging and shipping practices are not followed prior to the sample being tested by the lab. To be able to accurately compare and trend the lab results over time, all follow-up samples should be consistently taken from the same location using the same techniques as all previous samples.

•

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

•

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

HYDRAULIC OIL

•

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

•

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

•

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

Gearbox Samples: •

These samples can be taken during the oil change process.

•

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

•

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.

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.

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

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

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

Lubrication and Maintenance

GENERAL CAUTION ALL HANDLES, STEPS AND PLATFORMS MUST BE KEPT FREE OF GREASE, OIL, FUEL, MUD, SNOW, ICE AND FOREST DEBRIS. Clean around filler caps before checking or adding fluids.

Drain dirty oil while still warm.

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.

Do not exceed recommended fluid levels.

Always have a fire extinguisher at hand.

Clean around hydraulic fittings before breaking connection. Plug or cap immediately.

Clean up all spills immediately.

Always use clean oil and containers.

Service all hydraulic strainers and filters after the failure of a pump, motor, cylinder or valve.

Failures of this nature could contaminate the entire hydraulic system.

For safety, always lower boom assembly to the ground when leaving cab, leaving machine unattended or during service.

Always install door safety struts when working on machine.

Top up diesel fuel at each shift to reduce contamination by condensation.

Before welding on machine, be sure to disconnect all electrical connections and follow all servicing safety precautions as outlined in the WELDING, PRIOR TO of SECTION 1 in THIS MANUAL. When welding, secure ground connection as close to working position as possible to prevent arcing across machined surfaces or through bearings.

Clean away all branches, bark and chips.

Clean up all traces of oil to avoid fires.

Inspect the EXHAUST BLANKET and 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.

Clean fire suppression system sensors.

CHECK EMERGENCY EXITS, MONTHLY:~ Two alternate exit routes are provided: side door emergency exit and escape hatch/ emergency exit. These are only to be used if the front 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.

Refer to EMERGENCY EXIT MAINTENANCE GUIDE in SECTION 2 of the OPERATOR'S MANUAL for checking procedure.

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.

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.

1. Pine needles and bark when allowed to accumulate, form a fuel source that when ignited is extremely difficult to extinguish. A thorough program of regular cleaning and washing will reduce the possibility of a fire starting. In the event a fire does start, the regular cleaning program will improve the chances of successfully extinguishing a fire.

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

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

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

Also refer to FIRE PREVENTION in SECTION 1 of THIS MANUAL for additional information.

SCHEDULED MAINTENANCE In some cases, if the fan is not turning it may be necessary to bleed air from fan pump suction. Loosen suction flange connection at the fan pump. Retighten when oil starts to flow from this location.

Before attempting to disconnect hydraulic hoses or perform work on the boom system, ensure that:stick cylinders fully extended

Failure to vent air from the hydraulic system could cause serious damage to hydraulic components. Tighten plugs or fittings and clean up any spilled oil when completed.

Note: Changing strainers, filters and replacing the hydraulic oil tends to aerate the oil. For maximum pump life, the machine should sit for 1 hour after servicing to allow entrained air to escape from the oil prior to applying working pressures to the pumps.

ER BOOM SYSTEM WARNING This machine may be equipped with an ER boom system. Because of this, it may behave in an unexpected manner compared to a conventional boom system.

When performing maintenance procedures or setting up a machine equipped with an ER boom system, the following points must be noted: The main and stick boom cylinder circuits are connected hydraulically. Thus, disconnecting a hydraulic line to a boom cylinder may cause either boom to move unexpectedly. The boom may also move unexpectedly if a port relief adjusting screw is unscrewed (counterclockwise) too far and the pressure drops below that which is required to hold the weight of the boom and head. Ensure that the head is resting squarely on a solid footing and the stick cylinders are fully extended, tank pressure is relieved and engine is shut off before disconnecting any hydraulic lines.

860C-002

parking boom. FIG.2

(a) The machine is parked on level ground with the attachment on the ground (fig. 1). (b) The stick cylinders are fully extended (fig. 1) or the hoist cylinder fully collapsed (fig. 2). (c) The telescopic boom fully retracted (if equipped) and the tip of the stick boom supported at the rotator pin.

Do not rely on harvester attachment to support the boom system during servicing. Slow leakage in the hydraulic components can cause the attachment to move unexpectedly.

For additional safety precautions refer to ER BOOM SYSTEM PRECAUTIONS in SECTION 1 OF THIS MANUAL. Also note that because of the hydraulic connection between the main boom and ER cylinders, the ER cylinder can overpower the stick cylinders under certain conditions, causing the stick boom to move unexpectedly. This most often occurs when setting the MAIN BOOM UP relief valve, causing the stick to extend, but it may also happen at other times if the relief settings are not correct. Ensure that all personnel and equipment are clear of the boom path and that there is sufficient overhead clearance for the head to rise before making any adjustments.

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

Refer to the appropriate engine manufacturer's operation and maintenance manual for correct procedures and time intervals when servicing the engine oil and fuel filters. Read and understand the SAFETY section in each of these manuals.

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.

ENGINE OIL FILTER ENGINE FUEL FILTER

h855C-08

Tier III engines typically use filters with a very fine micron rating. If the fuel supply is dirty, the fuel filter must be replaced more frequently than recommended in the owner’s 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.

ENGINE OIL FILTER

Lubrication and Maintenance HYDRAULIC TANK PRESSURIZATION INSTRUCTIONS.

HYDRAULIC FILTER SERVICING GUIDELINES

IMPORTANT: PRESSURIZED HYDRAULIC TANK. 34.5 kPa (5 psi) MAXIMUM. Before servicing hydraulic system, release air pressure from tank using air vent valve.

IMPORTANT! NEVER PRE-FILL HYDRAULIC FILTERS

To release pressure from the hydraulic tank:

Tigercat generally does not recommend the prefilling of spin-on filters due to the risk of damage to the hydraulic system caused by unfiltered oil. Unfiltered oil used to pre-fill filters enters directly into the hydraulic circuit. Contaminants in unfiltered oil can cause significant and costly damage to hydraulic valves, pumps and motors.

The cleanliness of hydraulic oil cannot be guaranteed unless it is always prefiltered before use.

FILTER BREATHER

PRESSURE GAUGE 5 psi MAX (34.5 kPa)

IMPORTANT! Contaminated hydraulic fluid can lead to premature failure of hydraulic components and costly repairs.

Filters must be replaced at the recommended time intervals, Refer to scheduled maintenance in this section.

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

WARNING

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

•

Before servicing the machine, allow the hydraulic system and machine surfaces to cool down.

•

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

•

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

Wearing eye protection, release air from the hydraulic tank by opening the AIR VENT VALVE. Pull valve handle down 90° to open. Push valve handle up to close.

Note: Expelled air from vent valve will blow accumulated loose debris in the enclosure.

Releasing hydraulic tank pressure in the event of a hose breakage may reduce oil loss.

IMPORTANT: AIR VENT VALVE MUST BE OPENED BEFORE CHANGING HYDRAULIC FILTERS AND STRAINERS OR PERFORMING ANY OTHER SERVICE ON HYDRAULIC CIRCUITS. DO NOT OPERATE MACHINE WITH THE AIR VENT VALVE IN THE OPEN POSITION. During a filter change or return hose replacement, air is able to enter the return hydraulic circuit.

It is important to bleed as much of this air as possible out prior to restarting the machine. See HYDRAULIC OIL RETURN FILTERS "filter change procedure" for instructions on bleeding air from return circuit. AIR BUBBLES IN THE HYDRAULIC SYSTEM WILL DAMAGE THE PUMPS. After service is completed, close air vent valve and add air pressure from a clean air source to the hydraulic tank via the schrader valve. Do not exceed 34.5 kPa (5 psi).

AIR CLEANER The air cleaner on this machine uses 2 filter elements, a primary element and a safety element.

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

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

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

In addition to the LUBRICATION AND MAINTENANCE SCHEDULE outlined in THIS SECTION, the following instructions should also be noted: The most common and most damaging air intake servicing problems are: OVER SERVICING Filter elements increase in dust cleaning efficiency as dust builds up on the media. Looks can be deceiving. A filter that looks dirty is actually more efficient than one that is clean. A filter with dust build up on the media reaches nearly 100% dust cleaning efficiency. Only when a filter is so clogged with dirt that air restriction goes beyond engine manufacturer's guidelines, should a filter be replaced.

6. Inspect the new filter for damage.

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

8. Check connections and ducts for air tight fit.

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

NOTE: This does not apply to hydraulic oil or diesel engine filters.

This rubber valve on the tube of the air cleaner housing should be checked before every shift (8 hrs). If this valve is missing, damaged or has turned hard, it will cause the air cleaner to become ineffective. The valve should be replaced every 1000 Hours.

Remove the unloader valve from the tube of the air cleaner housing. A good valve is soft and flexible.

Check and clean the valve. If it was plugged, then check the filter elements as they may need to be replaced as well. Reattach the valve to the tube.

The valve should suck closed at about 1/3 of full throttle. When operating in high dust conditions this valve should be checked and squeezed frequently to release dust buildup.

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

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

The air intake should be checked daily to make sure that foreign materials have not plugged the air intake area.

The air cleaner is equipped with a scavenging system to unload dust and dirt from the air cleaner.

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

NOTE: This does not apply to hydraulic oil or diesel engine filters.

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

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

The engine air precleaner cleans engine air before it reaches the air cleaner filter elements. It removes contaminants such as dust, powder, insects, rain and snow. This precleaner is self powered and self cleaning requiring virtually no maintenance.

However, it should be checked periodically to make sure that foreign materials have not plugged the intake area or the exhaust port area.

HOW IT WORKS 1. Dirty air (1) enters the Precleaner, which is clamped onto the engine air intake.

2. Specially-designed vanes (2) , curved and angled to precisely direct air flow, move the dirty air toward the stainless steel impeller (3).

3. The dynamically balanced, one piece impeller (3) (only moving part) creates a tornado inside the housing.

4. The centrifugal force of the tornado expels the heavier than air dirt particles (4), chaff, dust, snow, rain, etc., out the discharge louver 5. Cleaned air (5) enters the engine air cleaner intake pipe, and the filter element has only the very light particles to remove.

Lubrication and Maintenance Alternate turning directions.

If you're always turning in the same direction, the undercarriage components on one side of the machine will wear at a different rate than those on the other side. To ensure even wear, pay attention to the way you're turning-and change directions whenever possible.

Protecting steel tracks Steel tracks are designed to perform in tough underfoot conditions. Take these steps to maximize service life and reduce operating costs.

Start every shift with a clean undercarriage.

When mud and debris build up on the lower part of your machine, components wear at a faster rate. Do not begin work until the undercarriage area is clean.

Inspect the undercarriage before you start working.

In addition to ensuring that the undercarriage is clean, spend a couple of minutes on a visual inspection. Check for loose bolts, leaky seals and abnormal wear patterns. When you spot potential problems early, you can often prevent them from turning into bigger issues that reduce component life significantly or cause expensive unscheduled downtime.

Don't spin the tracks.

Track spinning, reduces production, it increases fuel consumption, without a corresponding increase in productivity. And it accelerates undercarriage wear, so your costs escalate.

Grouser bars are especially prone to wear problems associated with track slippage.

Make gradual turns instead of counterrotations.

Counter-rotating accelerates wear on the tracks and other undercarriage components. Don't use that technique unless job conditions demand it. Instead, turn the machine gradually while slowly moving forward or reverse. Gradual turns minimize cuts, tears and excessive wear in the undercarriage. They also reduce damage to soft or sensitive work surfaces.

In the event a counter rotation is required some Feller Buncher operators will carefully push the boom and felling head down against a suitable obstacle and lift the forward or rear sections of the track off the ground. The operator will then counter rotate the tracks while swinging the upper frame. This will disengage most of the track length from the ground during the counter rotation resulting in less site damage and potentially less track wear. This is a complex maneuver and should only be completed with fully trained and experienced operators working in stable ground conditions.

Watch your speed.

There are times when a job requires higher speed operation, but the fact is, wear accelerates as speed increases. Links, rollers and idlers are particularly vulnerable. Keep them working longer by controlling your speed.

Avoid unnecessary reverse operation.

Operating in reverse-even at slow speedscompounds bushing and sprocket wear as the track tension loads are applied to the top side of the chain. So avoid an unproductive reverse operation.

Work up or down a slope whenever possible.

Working across a slope can shorten undercarriage component life, so try to structure the job with minimal cross-slope activity.

3.37

Tigercat H855C/LH855C Harvester

Lubrication and Maintenance

Watch transition areas.

Try to minimize travel over transition obstacles as this accelerates undercarriage wear. If you must go across a transition, position the machine 90° to the transition. Without ground support, the undercarriage is subjected to side stresses that can result in rapid, excessive wear.

Other factors:

Configuration refers to the way your machine is equipped and is therefore something you can control. To minimize undercarriage wear on steel-track machines, always use the narrowest track shoe possible that meets your flotation requirements. If you work in very sticky materials, consider using center-punched track shoes to reduce material packing in the undercarriage area.

Maintenance discipline plays a big role in undercarriage component life. One of the most critical maintenance practices is track adjustment.

Tight track is the number-one "track killer." But whether your track is too loose or too tight, improper adjustment accelerates wear which can increase downtime and repair costs. Follow the manufacturer's recommendations for track adjustment, and always perform the adjustment in the machine's working environment. A second important maintenance process is cleaning the undercarriage. To maximize wear life, remove mud and debris at the end of every shift, or more frequently if necessary.

Application refers to the type of work you do.

Bunching, loading, grading, digging and trenching are a few examples. This factor is largely beyond your control, but generally speaking, the more you work in high horsepower, high-torque applications, the faster your undercarriage will wear.

Material type is another key contributor to undercarriage wear that is outside your control, the more abrasive the material, the more rapid the wear rate.

Talk to the experts: Undercarriage components are expensive!

To get long life and maximum value from your investment, consult with a dealer or factory rep that really knows the undercarriage business.

Ask for advice on operating techniques. Explore relevant application, material and terrain issues.

Fine-tune your maintenance processes. Working together with an undercarriage expert, you can manage your equipment investment over the long term.

Terrain, a third uncontrollable factor, describes the contours and slopes at your job site. The more time you spend in rugged, sloped areas, the faster your undercarriage will wear out.

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

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

• Four bolts and washer

WASHERS BOLTS FLANGE CLAMP

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

2. Lubricate the O-ring.

3. Position flange and clamp halves.

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

5. Hand tighten bolts.

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