Serial numbers: S855D

85552001 TO 85553000

LS855D

85502001 TO 85503000

NOTE: The 4th digit in the machine serial number indicates the machine model type. For example, 5 = Shovel Logger and 0 = leveling Shovel Logger. For simplicity throughout this manual the 4th digit has been replaced with an asterisk to indicate that both types of machine models are affected, ie: 855*2001 TO 855*3000.

The S855D/LS855D Shovel Loggers are designed for log transferring, loading, and shovel logging (hoe-chucking) by swinging logs closer to the roadside minimizing ground surface impact and damage.

The operator's manual will assist the operator with the techniques of proper and safe operation of the S855D/ LS855D Shovel Loggers. There is also important information regarding the safe operation of the attachment. The service manual contains safety and servicing procedures and a preventive maintenance schedule to ensure optimum machine performance.

Section 1 in both the operator's manual and the service manual contains safety information that must be followed. As well, throughout the rest of the manuals, DANGER, WARNING and CAUTION notices are displayed where necessary, drawing attention to possible hazards when performing certain procedures.

Only trained personnel should be allowed to operate or work on the machine.

The information contained in this manual is current at time of printing. Improvements to the machine are on-going and may not be covered, therefore in these cases contact your Tigercat dealer for the appropriate information.

The phrase “and up” appearing in this manual after the serial number implies the related information is current for any machine serial number HIGHER than the serial number preceding the “and up”.

Introduction

THIS OPERATOR ENCLOSURE MEETS THE FOLLOWING STANDARDS: • ISO 8083:1989 11 600J FALLING OBJECTS PROTECTION STRUCTURES (FOPS) • ISO 8084:1993 OPERATOR PROTECTION STRUCTURES (OPS) • ISO 8082-2:2011 ROLL OVER PROTECTION STRUCTURES (ROPS) • OREGON OSHA 437-007-0775:14A TIP-OVER PROTECTION STRUCTURES (TOPS) • ISO 2867:1994 • SAE J1356: FEB. 1988 • OREGON OSHA 437-007-0775:14B,C • AS 4988 2002 * MODIFICATIONS AND REPAIRS: The integrity of the FOPS, OPS, ROPS, TOPS 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 the certification of approval of the FOPS, OPS, ROPS, TOPS 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 the work is carried out in the factory approved manner.

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

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

Operator cabs are designed to ROPS, TOPS, FOPS, OPS standards so they will withstand force and absorb energy during a roll over (ROPS), 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 FOPS, OPS, ROPS, TOPS 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.

Safety

WORKING WITH OIL

SAFETY HAZARDS – VITON SEALS

Direct contact with oil implies a risk of skin complaints (example: eczema). Observe strict hygiene.

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).

Observe the following when working with oil: • Oils used in this machine may be hot enough to cause serious burns.

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

• Avoid contact with oil, particularly heated oil.

• Wash off oil on the skin immediately with soap and water.

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

• Wear protective gloves. Clean hands before putting on gloves. Apply protective cream to the hands to make washing easier.

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

• Don't put oily rags in your pockets.

• If these are found, do not Touch!

• Change oil soiled clothing as soon as possible.

• 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.

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

• Attend to cuts and abrasions immediately. Clean them and apply first-aid.

• Avoid breathing in oil fumes.

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

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

• Any soiled rags and gloves must be safely discarded after use.

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

Safety

Tigercat S855D/LS855D Shovel Logger

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

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

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

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.

Maintain a minimum distance of 3 m (10 ft) between the machine, including the boom or attachment, and any power line carrying up to 50,000 V. Add 1.5 m (5 ft) for each 150,000 V increment beyond 50,000 V. For example, if a power line carries 350,000 V, keep back at least 6 m (20 ft).

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

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

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

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, adhere strictly to these regulations for your own protection.

If the machine must be transported, make sure that it is adequately secured to the transporting vehicle.

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

CAB EXITS Before moving the machine to the work site, check to ensure that all doors, panels, and access covers are installed properly and secured.

There are three ways to exit the cab in case of an emergency.

FRONT DOOR This is also the main point of entry and is the only door that should be used under normal operating conditions to enter or leave the cab. This door is also equipped with a safety interlock switch. See SAFETY INTERLOCK SWITCH ON FRONT DOOR in this section.

Safety All three exits should be checked to make sure they are operational and will function in an emergency. The safety interlock mechanism on the front door or the side door and escape hatch retaining mechanisms must not be tampered with or compromised.

IMPORTANT! Unlock both doors before operating machine to allow opening from the outside in case of an emergency. Make sure the doors are operational, open the doors twice, once using the exterior latch handle and once using the interior handle.

For additional information, refer to EMERGENCY EXITS in SECTION 2.

SIDE DOOR Should be used for emergency exits only. Do not use this door to routinely enter or leave the cab. This door is not equipped with a safety interlock switch and therefore when left open will not deactivate the pilot controls in the cab. Shut OFF the engine before using the side door exit.

ESCAPE HATCH This is a third cab exit for use if the side exit or front door exit become blocked.

This hatch is not equipped with a safety interlock switch and therefore when left open will not deactivate the pilot controls in the cab. Shut OFF the engine before using the escape hatch exit.

It is important the operator of the machine be familiar with these emergency exits and how to use them.

All operators should practice using all the cab exits to become familiar with escape procedures should they need to perform them in the dark, when the machine is in a rolled position, or other possible adverse conditions.

MACHINE STABILITY AND TRACTION – MACHINES WITHOUT LEVELER

WARNING

When working on slopes, travel straight up or down the slope to prevent roll-over.

Never travel across a steep slope or side hill: • As logs are added to the accumulator pocket the handling and the stability of the machine will change.

• To avoid tip over, keep the attachment as low as possible to maintain a low centre of gravity.

Keep the cab doors closed when driving or steering the machine to prevent accidental entry of branches and debris into the cab.

• Be prepared to dump the load in case of an emergency.

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

Keep the cab doors closed and use seat belt when driving or steering the machine to prevent being thrown from the operator's cab.

Secure loose items in the cab.

Prior to commencing work, check all equipment controls to make sure the machine responds correctly.

Make sure that all safety screens and guards including the escape hatch are installed and properly secured.

Rest the attachment on the ground when operation is stopped, regardless if the engine is running or shut off.

Operate the machine only from a seated position in the operator’s seat.

Watch for ground hazards such as metal debris, wire fencing or rocks.

When travelling, position the attachment and boom so as not to impair vision.

If vision is limited by dust, smoke, fog, rain or snow, stop the machine until visibility is restored.

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

MACHINE STABILITY AND TRACTION – MACHINES WITH LEVELER This machine is designed to operate on rough terrain and slopes commonly found in forestry applications.

However, ground conditions vary greatly with changing soil types, slope angles, moisture, snow and ice, rocks, boulders and stumps, and fallen trees. All of these factors affect the machine’s stability against tip-over and traction to resist slipping. This machine may not be capable of operating on some ground conditions, and must be used with caution.

860C-009

20°

Whenever possible work within the normal working range of the boom system as shown in FIG. 1.

NOTE: In any boom position, both inside and outside of the normal operating range, there is a risk of instability and tipping.

When it is necessary to work outside of the normal working range, be aware the stability of the machine is reduced. The risk of tipping is increased while operating in the reduced stability working range.

FIG.1– Working Ranges

Normal Working Range of Boom System Reduced Stability Working Range Track Gearbox at Rear of Undercarriage Uphill

Be aware the machine is in its least stable position on a slope with the boom to the rear.

• 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.

• 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.

All efforts have been made in the design of the machine to reduce the risk of tipping, however it is not possible to eliminate the risk of tipping.

1.14

Tigercat S855D/LS855D Shovel Logger

Safety CLIMBING A SLOPE

• Never travel across a steep slope or side hill.

• Carry any load on the uphill side of the machine.

• Do not lift or move objects that exceed machine stability.

• Be prepared to release the load in case it causes the machine to tip.

• 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.

801568

FIG.3– Climbing A Slope

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

When climbing a slope:

• 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 particularly aware of machine stability when changing directions on, or travelling back down a slope.

• Keep the attachment close to the ground.

• Keep the track drive gearbox at the rear of the machine.

• Keep the boom to the front of the machine.

DESCENDING A SLOPE

• As you gain experience, recognize 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 these factors can result in a shallow slope posing greater risk than a relatively steeper slope.

Do not attempt to work on slopes if conditions are beyond your ability level.

WARNING For leveling machines that work on slopes, select the system cooling fan switch FULL ON position if either of the following product support bulletins (PSB) have not been completed:

801567

FIG.4– Descending A Slope

When descending a slope: • Keep the attachment close to the ground.

• Keep the track drive gearbox at the front of the machine.

MOVING TREES – SHOVEL LOGGER

SOFT GROUND APPLICATIONS

Pieces of wood and debris from the ground become potentially dangerous missiles when thrown from these machines.

Shovel logging is often carried out over soft ground conditions, sometimes too soft to support the weight of the machine. In these conditions timber mats or fallen trees are used as a base to support the machine. The machine can slide off this support base or mat and into the surrounding soft soils, possibly completely submerging the operator’s cab. Ensure all doors and roof exits are in proper working order to provide possible escape routes.

Inspect grapple for stress cracks.

When moving from tree to tree, take care not to make contact with other vegetation or debris that could be dislodged causing a rolling or falling hazard.

Do not over load grapple.

Work within your operating skills, do not attempt to move a tree that is too large for the grapple or boom system to handle.

Operate so the load is not directed at or will not enter the area of people, livestock, buildings or other machines.

Know and control the direction the tree will move to prevent injury to co-workers or damage to other vehicles.

When backing up, watch out for obstacles in your path.

Travel with the load and grapple as close to the ground as possible, never elevate the load and grapple unless necessary.

If the machine begins to sink, immediately; 1. Turn off the engine 2. Choose the upward direction escape route 3. Exit the cab

WARNING Do not operate this machine to lift or move any objects other than what it is designed to lift or move.

The boom system is intended for use in shovel logging applications only.

• Do not use the boom to service other equipment.

Never use this machine to clear a logging deck on a new tract of timber when the rest of the equipment and operator's are also moving in. Pre-plan to clear decks in advance before other equipment arrives.

• Do not use the boom to lift items such as tires, engines, cylinders, boom components, etc.

Never work alone. Regularly inform other crew members of your intentions, location and length of time to perform duties.

• Do not modify the boom system.

• Do not add hooks or lugs to the boom for the purpose of attaching lifting rigging.

Park machine at least 15 m (50 ft) away from other equipment and in a cleared area. In the event of a fire, this distance will minimize the chance of the fire spreading to other equipment.

Before leaving operator's cab, lower the grapple attachment onto the ground.

If out of the operator's cab for an extended period shut the machine off.

When moving logs with the boom system, keep the logs a safe distance from the cab and machine to prevent possible injury from flying window fragments, or causing serious damage to the machine.

• Do not use the attachment for any purpose other than the intended shovel logging function.

Maintain a safe operating distance between the machine and workers and all other personnel.

Run chain saw only at recommended cutting speed.

• Do not use the boom to lift items such as tires, engines, cylinders, boom components, etc.

Check the saw housing area is clear and undamaged.

• Do not modify the boom system.

Identify your approach to the tree before making it.

• Do not add hooks or lugs to the boom for the purpose of attaching lifting rigging.

Know where your co-workers are. Make sure they are out of harm's way before beginning the cut.

• Do not use the attachment for any purpose other than the intended felling function.

Work within your operating skills, do not attempt to cut down a tree that is too large for the felling head.

Maintain a safe operating distance between the machine and workers and all other personnel.

It is the duty of the operator to ensure that no person approach the machine while in use.

Be alert for dead or decaying trees. Tops can break off while cutting.

Failure to follow the above instructions could result in serious injury or death.

WARNING Avoid the risk of chain shot. Never operate the attachment so the saw bar is directly in line with the cab or any personnel!

Never use this machine to clear a logging deck on a new tract of timber when the rest of the equipment and operator's are also moving in. Preplan to clear decks in advance before other equipment arrives.

Operate so that chips and debris are not directed at people, livestock, houses, buildings, roads or other machines.

Be particularly observant with the zone in line with the chain saw.

Never leave the machine unattended while the engine is running.

When making the cut, properly position felling head in front of tree.

Know and control the direction the tree will fall to prevent injury to co-workers or damage other vehicles.

When backing away from a cut, watch out for obstacles in your path. Travel with felling head as close to the ground as possible, never elevate the felling head unless necessary.

1.19

Safety

Tigercat S855D/LS855D Shovel Logger

Rest the felling attachment on the ground when operation is stopped, regardless if the engine is running or shut off.

WARNING

CHAIN SHOT – LOGGING SAFETY Chain Shot is the high-speed ejection of chain parts that can occur in the event of a derailed or broken chain.

While the risk of a chain shot event can't be eliminated, it can be minimized by following some simple operational recommendations.

WARNING

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

Maintain a safe operating distance between the machine and other personnel (at least 150 m (500 ft) away).

WARNING

There is risk of serious injury or death to machine operators and bystanders from chain shot. Follow the manufacturer's application and maintenance instructions and those provided for the equipment on which the cutting chain is used.

Generally, chain shot originates near the driven end of the cutting system, but can also originate from the guide bar tip area. In either situation, it poses the same risk of serious injury or death to the machine operator and any ground personnel nearby.

Never operate the boom or attachment over the heads of bystanders.

Use only prearranged and approved signalling practices.

Before leaving operator's cab, apply the parking brake or swing brake and lower the felling attachment onto the ground.

CAN CHAIN SHOT BE ELIMINATED?

The stay back distance will help reduce the risk of a chain shot injury, but not eliminate it.

The following items should be observed in accordance with the saw manufacturer's recommendations: • Cutting system maintenance.

• Saw chain maintenance.

• Clean and dress guide bars on a regular basis.

• Replace worn drive sprockets.

575-503

A Shot Cone Zone

In simple terms, no, it can’t. Properly designed chain shot guards and shields reduce the danger of a chain shot from the drive sprocket area. However, there is currently no known way to place similar guards in the guide bar tip area without significant disruption to the cutting operation. Because no guarding is currently possible in the guide bar tip area, chain shots can be generated and pose the same risk of serious injury or death as those generated at the drive sprocket area.

Care should be taken to minimize the exposure of the machine operator and ground personnel to the cutting plane of the cutting system and Shot Cone Zone.

Ground personnel should stay back at least 150 m (500 ft) away and outside the Shot Cone Zone of a working machine.

Do not exceed the manufacturer’s recommendations for chain speed. Cutting systems must be inspected frequently. Dull, damaged saw chains should be immediately removed from service for inspection, repair or replacement. Saw chain loops which have broken twice, must be removed from service.

Drive sprockets must be aligned with the groove of the guide bar. Ensure the saw chain/guide bar lubrication system is functioning properly: 0.404 – pitch cutting systems should use approximately 7.6 L (2 US gal) of guide bar/chain lubricant or more per eight hour shift in harvesting operations – more when used in processing operations. Three-quarter-pitch cutting systems should use approximately 9.5 L (2.5 US gal) or more per eight hour shift in harvesting applications – more when used in processing operations.

1.22

Tigercat S855D/LS855D Shovel Logger OPERATIONAL RECOMMENDATIONS

Safety IN COLD CUTTING CONDITIONS: • Use a lighter weight lubricant, if possible, doubling the flow rate.

In general: • Never begin a cut with the machine operator and ground personnel in the Shot Cone Zone.

• Periodically cycle the guide bar without cutting (air cuts), this increases lubricant present on the cutting system.

• Begin a cut as close to the ground as possible.

• Use new and approved parts when assembling and repairing chain.

• Maintain chain in agreement with chain manufacturer’s recommendations.

• Reduce bar feed force.

CONDUCT PROPER GUIDE BAR MAINTENANCE:

• Never force a dull chain to cut. A sharp chain places less wear and tear on the cutting system.

• Clean the guide bar groove from bar tip to bar tail and keep the oil hole open.

• Chain should be sharpened or replaced with a sharp chain at least once per operational shift, or more often if damaged.

• Turn the guide bar over on a daily basis to equalize wear.

• Cycle the guide bar several times to remove moisture from the guide bar tip.

• Depth gauges (rakers) must be maintained through the life of a chain.

• Ensure you maintain proper chain tension, checking it often.

• Never exceed your chain manufacturer’s operation recommendations.

• During work breaks and at the end of each shift, relieve chain tension to prevent damage to the guide bar tip, saw motor and/or the chain as the chain cools and contracts.

• Reduce chain speed.

In simple terms, your attachment, when operational, should be treated as if it is two loaded guns (the bar tip and the bar tail) that pose a risk of serious injury or death to the machine operator and ground personnel.

The risk of a chain shot event cannot be eliminated, but the risks can be reduced by following the recommendations provided by your cutting system manufacturer, and the operational recommendations presented here.

1.23

Safety

Tigercat S855D/LS855D Shovel Logger

FELLER DIRECTIONAL HEAD CONTACT WITH CAB

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

The boom of this machine is designed to enable the feller directional head to be tucked in close to the operator’s cab. This ability maximizes the manoeuvrability of the feller directional head to work around standing trees and while thinning in dense stands. See both the upper and lower sections of Figure 1.

Working with the feller directional head in close to the machine: • 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 feller directional 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.

800-01A

FIGURE 1. HEAD TUCKED IN CLOSE

FIGURE 2. HEAD SWINGING 1.24

Tigercat S855D/LS855D Shovel Logger

Safety

However operators of these machines are advised that working with the feller directional head in close to the machine also increases the chances of the feller directional 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.

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

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 feller directional head, the following procedures must be followed during the operation of the machine to avoid contact of the feller directional head with the cab.

1. When nearing the boom positions shown in Figure 1: • Keep the head in the upright felling position.

• Do not tilt the head from the upright felling position to horizontal position as the saw housing may contact the cab.

• Reduce the speed of boom movement. Rapid movement could cause the base of the feller directional 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 feller directional head in close to the machine while the feller directional 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.

Safety

Tigercat S855D/LS855D Shovel Logger WARNING

Diesel fuel or hydraulic oil 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.

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

Shut off engine. Only remove coolant fill cap when cool enough to touch with bare hands. Slowly loosen cap to first stop to relieve pressure before removing completely.

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.

Do not change any pressure or relief setting unless Tigercat authorized instruction has been obtained.

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

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, stop the engine and relieve trapped pressure before performing work on components, or disconnecting any hoses. Accumulators will self drain within two minutes of stopping the engine.

Refer to PARKING THE MACHINE in THIS SECTION.

Keep your hands, feet, head, and loose clothing away from power driven parts. Tie long hair behind your head.

Remove rings and other jewelry to prevent electrical shorts and entanglement in moving parts.

Be aware of machine pinch points that could cause injury. Never place body parts within the range of motion of the working parts of the machine.

FLUID INJECTION INJURY

Safety IN THE EVENT OF ANY SUSPECTED FLUID INJECTION INJURY:

WARNING

• REPORT THE INJURY TO YOUR SUPERVISOR IMMEDIATELY.

Diesel fuel or hydraulic oil 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.

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.

• 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. Wear thick protective gloves.

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.

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

• Be sure to wear safety goggles for eye protection.

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

• 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.

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

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

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

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

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

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

1.35

Safety 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.

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 seeking medical attention 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.

• Make sure 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.

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 ft) within the soil around the strike point.

Thunder 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.

1.36

Tigercat S855D/LS855D Shovel Logger

Safety

LIGHTNING SAFETY

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

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

1.37

Safety 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.

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

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

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

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

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

• Avoid entering any small enclosures or shelters.

Tigercat S855D/LS855D Shovel Logger 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

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

http://www.lightningsafety.noaa.gov

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

• National Lightning Safety Institute http://www.lightningsafety.com

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

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

• Do not use the telephone except for emergencies.

Safety

FIRE PREVENTION

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

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

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

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

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.

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

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

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.

Remove debris and blow out dust regularly from the air intake doors, engine radiator and charge air cooler, hydraulic oil cooler, diesel fuel cooler and air conditioning condenser core to prevent overheating of the engine and hydraulics and to maintain efficient operation of the machine. Refer to CLEANING COOLER PACKAGE in SECTION 3.

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.

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.

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

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

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

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

1.39

Safety

Tigercat S855D/LS855D Shovel Logger

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

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

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 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.

• 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.

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.

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

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

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

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

NOTICE

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.

• Ensure 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 SUPPRESSION SYSTEM (OPTIONAL) in SECTION 2.

• Ensure that your fire suppression system** is charged and in working order. Refer to FIRE SUPPRESSION SYSTEM (OPTIONAL) in SECTION 2.

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

• 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:

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

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

1.40

Tigercat S855D/LS855D Shovel Logger • Workers designated to use fire fighting equipment as part of an emergency action plan must receive full and proper training from a qualified instructor.

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

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

• 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.

• 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.

Safety WHAT TO DO WHEN A MACHINE FIRE OCCURS If operating the machine when a fire occurs: 1. Lower all working attachments to the ground.

2. Shut the engine off.

3. Activate the fire suppression system**.

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.

Before deciding to fight the fire, be certain that: 8. The fire is small and not rapidly spreading.

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

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

11. 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.

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

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

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

1.41

Safety

Tigercat S855D/LS855D Shovel Logger • 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.

• 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.

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

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

WHAT TO DO AFTER A MACHINE FIRE HAS OCCURRED Before returning the machine to work.

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

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

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

• Notify your equipment dealer and/or Tigercat Industries Inc. by completing an incident report, Tigercat form number 5101. *NOTE: Fire detection systems are offered by Tigercat as an optional installation on some Tigercat product lines.

Safety

DRY CHEMICAL CLEANUP PROCEDURES CAUTION 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.

IMPORTANT! 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.

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

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

The caked dry chemical when exposed to moisture is also mildly acidic. When the break down procedure has been completed, neutralize the dry chemical.

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

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

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

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.

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.

COOLING FAN – SWITCH (B)

SWING BRAKE – SWITCH (A)

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

CAUTION Turning ON the swing brake while the boom is moving can damage the gearbox.

NEVER operate the tracks with the swing brake ON as boom contact with the ground will damage the swing gearbox.

This is a two position switch labeled ON/OFF. Placing this switch in the ON position will apply the swing brake and prevent the upper structure from turning. The swing brake is a spring apply, hydraulic release, multi-disc brake. The brake is also engaged whenever the pilot system is shut off. As a safety precaution, the brake should be applied with this switch when leaving the cab.

AUTO POSITION – AUTO 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 or slow down 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.

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 engine speed. This is to ensure that sufficient air flow is available for the cab A/C even while the machine is still warming up.

2.22

Tigercat S855D/LS855D Shovel Logger FULL ON (OVERRIDE) – DOWN 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: Placing the switch in the FULL ON position activates the computer alarm to advise the switch has been placed in the FULL ON position. Also while the switch is in the FULL ON position the Automatic Cleaning cycle is prevented.

CAUTION Before placing the fan switch in the CLEAN position make sure there are no personnel near the rear of the machine in the area where the fan will expel debris.

Controls and Operation CLEAN – UP POSITION Momentarily pressing the switch to the CLEAN position will automatically start 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 the radiator.

NOTE: 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) when the switch is in the AUTO position. Refer to COMPUTER – MAIN MENU – ADJUST MENU – MACHINE PARAMETERS in THIS SECTION.

WARNING For leveling machines that work on slopes, select the system cooling fan switch FULL ON position if the following product support bulletins (PSB) have not been completed: PSB 2580 (revision 2) PSB 2669 Selecting fan FULL ON prevents the system from activating the timed purge function, which may cause the machine to coast down the slope.

Controls and Operation

AUTOMATIC OPERATION

DISCHARGE OF THE SYSTEM

There are seven thermostats mounted in the engine and hydraulic enclosures which are wired to the control panel. The thermostats are automatic heat detection devices and are set to close at 177°C (350°F). When a thermostat closes it sends an electrical signal to the control panel which activates 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. The control panel will also automatically shut down the engine and all electrical power.

The fire suppression system can also be activated manually using the manual actuation switch.

To manually operate the system: 1. Safely lower the boom to the ground.

2. Pull locking pin (1).

3. Press red FIRE button.

An electrical signal is sent to the control panel from the manual actuation switch which activates the system.

NOTE: The engine does not shut down automatically when the fire suppression system is activated using the nitrogen actuator. When using the nitrogen actuator to activate the fire suppression system the operator must shut the engine off manually.

The automatic engine shutdown feature will either shutdown the engine immediately the fire suppression system is discharged (non-leveling machines) or will delay the shutdown for a period of between 10 to 15 seconds for leveling 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 engine shutdown delay feature by pressing the RELAY 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 RELAY RESET button does not delay the discharge of the fire suppression system.

NOTE: In the event of a power failure the system can be activated by the Nitrogen Actuator located on the front left post of the cab.

1. Remove Locking Pin (2).

2. Strike down hard on actuator knob.

WEEKLY:

AVOIDING DAMAGE AND FALSE DISCHARGES DURING MACHINE SERVICE:

1. Inspect all parts for damage, rust, corrosion or dirt. Replace any damaged parts immediately.

2. All components are in place and unobstructed.

3. All chemical delivery hoses and nozzles are connected and tight.

4. Check fire suppression electrical network for cut, frayed, stripped or damaged wires.

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.

H845D-014

TYPICAL THERMOSTAT

5. Ensure thermostats are clean.

6. Operate the machine and press the “Push to TEST” button to confirm the automatic engine shutdown feature is working. Pressing the “Push to Test” (Amerex diamond) button will illuminate all LEDs, sound the alarm and engage the relay. The “Push to Test” function will not cause a system discharge.

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.

H845C-54

The purpose of the vacuum pump system is to hold the hydraulic oil in the tank when servicing pumps and other hydraulic components, minimizing oil spill. When activated, a solenoid valve closes off the hydraulic tank breather air supply. The pump removes tank air to create a vacuum, which then holds the oil in the hydraulic tank. This system eliminates the need to drain the hydraulic tank beforehand.

With the ignition key OFF, activate the vacuum pump by placing the switch in the ON position.

NOTE: When the ignition key is in the RUN position, the vacuum pump system will not start.

Alternatively if the vacuum pump is on, the engine cannot be started. The vacuum pump also will not start if the battery disconnect switch is in the OFF position.

2.34

Tigercat S855D/LS855D Shovel Logger Do not use the vacuum pump when changing hydraulic filters, instead use the Air Vent Valve to release pressure from the hydraulic tank. Using the vacuum pump system while changing filters creates the risk of introducing much more air into the hydraulic system.

Refer to Refer to SEAT ADJUSTMENTS in THIS SECTION.

RIDES TOO SOFT OR BOTTOMS OUT AND PINCHES OPERATOR The air ride control valve has under pressurized the seat air suspension ride adjustment Insufficient pressure exaggerates the knee-action movement of the seat. This usually happens because the operator is trying to lower the seat by decreasing the amount of air pressure instead of using the height adjustment lever. Refer to SEAT ADJUSTMENTS in THIS SECTION.

SEAT TOO HIGH/SEAT TOO LOW There are several things which can cause improper seat height. Refer to Refer to SEAT ADJUSTMENTS in THIS SECTION 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.

LEVELER ADJUSTMENT SETTINGS

START RAMP

These settings (defined below) fine tune the operating speeds, start/stop ramps and cylinder tracking for the leveler functions.

This is the amount of time in ms that it takes for the current to get from the Min Current value to the Max Current when turning on a function. A higher setting will cause a delay in the time that it takes the function to reach top speed. Note that if the ms setting is set to 0ms then the min current setting is negated as the function will start at max current as soon as it is turned on.

Current [mA]

A = Current range min current

STOP RAMP

Min current A Lever position

MIN = MINIMUM CURRENT (MA) 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.

This is the amount of time in ms that it takes for the current to get from the Max Current to the Min current when turning off a function. A higher setting will cause a delay in the time that it takes for the function to come to a stop from top speed. Note that if the ms setting is set at 0ms then the min current setting is negated and the function would stop as soon as it is turned off.

Below is a typical graph showing the four settings.

Current [mA] Max current

The Min current is adjusted to a value that causes the function to just begin to creep.

REAR LEVELING SPEED Lever position

This adjusts the left and right cylinder speeds proportionally to their respective Max mA – (cylinder retract) settings.

Maximum current settings control the maximum speed the function will operate at. Increasing this value will increase the travel speed of the cylinder.

NOTE: The mA + (extend) and mA – (retract) settings for the left and right cylinders need to be set separately to avoid tracking (one cylinder extending or retracting faster than the other).

Engine idle too long. Shutdown engine to prevent damage to emission control system.

This message will be displayed, alarm light will flash and alarm will sound when an aftertreatment technical fault is detected. Action to correct the problem should be taken immediately to avoid affecting engine performance and damage to the diesel oxidation catalyst /selective catalytic reduction (DOC/SCR) aftertreatment system components.

This message results in the following derate sequence if no action is taken to correct the problem: • Beginning immediately after an aftertreatment system technical message there will be a ramp down of Torque by 25% over 25 minutes.

• After 1 hour at reduced torque there will be a ramp down of Engine Speed by 60% and Torque by 65% over 40 minutes.

This message will be displayed, alarm light will flash and alarm will sound when this engine has idled for more than nine consecutive hours.

Shutdown engine to prevent damage to the emission control system.

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

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

• After 50 minutes at derated engine speed and torque the engine is derated to idle within 30 minutes.

• Some less severe technical faults can be fixed at any time, even after then engine has been fully derated to idle speed.

• More severe technical faults will result in an engine lockout when the engine has derated to idle and there have been three restarts (re detects). Once locked out the engine will only operate at idle. Action to correct the original cause(s) of the lockout must be taken before the engine can be reset.

DEF is injected into the exhaust gas stream during normal operation of the Selective Catalytic Reduction (SCR) aftertreatment system.

Use of other fluids may cause component damage, or a fire risk which could result in death or serious injury.

DEF quality low.

This message will be displayed, alarm light will flash and alarm will sound when a diesel fluid quality problem is detected. Action to correct the problem should be taken immediately to avoid affecting engine performance and damage to aftertreatment system components.

This message results in the following derate and engine lockout sequence if no action is taken to correct the problem: • Beginning 1 hour after a DEF quality message there will be a ramp down of Engine Speed by 60% and torque by 65% over 40 minutes.

• After 2 hours at derated engine speed and torque the engine is derated to idle within 30 minutes.

To correct the DEF quality problem clean the area around the DEF tank then drain and refill the tank with clean DEF which meets ISO 22241 specifications.

Alert engine fault message(s) will be displayed, alarm light will flash and alarm will sound when an alert engine fault message is received from the engine electronic control unit.

They provide the SPN code (suspect parameter number) as well as a message describing the fault (when available).

Alert engine fault codes are lower priority messages than critical level engine fault code messages. Alert messages can be hidden but action (service engine) is required to resolve the cause of the fault.

An example of an alert engine fault message is shown above.

Note that some less common engine fault codes will appear without a message describing the fault.

Make a note of the SPN code and contact service for more information.

Refer to ENGINE OPERATION AND MAINTENANCE MANUAL for specific information regarding the engine and aftertreatment system.

NOTE: Contact your Tigercat dealer to obtain an Engine Fault Codes chart. An up to date copy should be kept in the Manual’s Box (in the cab). The chart is updated regularly by the engine manufacturer, so it is important to check periodically with the Tigercat dealer to ensure that you have a current copy of the Engine Fault Codes chart.

Controls and Operation

STOPPING ENGINE

IMPORTANT! Only use the master disconnect to shut off a running machine in an emergency. A fault code will be logged by the ECU on the engine for improper shut down and power down.

IMPORTANT! Stopping the engine immediately after it has been working under load can result in overheating and premature wear of the engine components. Follow the stopping procedure outlined below to allow the engine to cool.

10. Perform daily maintenance at the end of the shift (greasing, clean engine compartment etc.). This allows the machine time to cool down while under the watchful eye of the operator.

• Follow this engine shut down procedure. The important benefits are: • Extended life of engine, cooling and exhaust systems.

• Reduced risk of post shutdown fires.

1. Interior of machine cools significantly reducing risk of touching hot surfaces.

2. Turn the saw switch to the OFF position and STOP the attachment. This should be done before leaving the cutting area (Feller Director only).

3. Find a clear and level area at least 15 m (50 ft) from any other equipment to park the machine.

4. Park the machine and lower the attachment onto firm ground.

5. Reduce engine speed to low engine speed, de-activate the pilot system and let engine run at low idle speed for approximately three minutes minimum to allow 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.

6. Open power roof and place fan switch in Full ON position.

7. Do not increase engine speed before shut-off.

8. Place fan switch in AUTO position.

9. Stop engine by turning ignition key switch to the OFF position.

NOTE: that whenever the engine is stopped all DEF solution is pumped back to tank before the engine power system is turned off. This process takes approximately 90 seconds.

Refer to AFTERTREATMENT SYSTEM in SECTION 3 for more information. Also this machine is equipped with an After Run/ Accessory Relay which delays by 90 seconds the power disconnect to engine related fuses and relays (ECU /ATS relay, NOx Sensor relay, NOx Sensor fuse, ECU Power fuse, DCU fuse).

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 logging operations should be done in LOW. When in DRIVE the machine moves faster but with less drive force. Travelling over longer distances 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 BOOM CONTROLSin THIS SECTION. 2. Place swing brake switch in OFF position.

3. Move throttle control to the high engine speed position.

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

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 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.

Refer to HYDRAULIC SYSTEM OPERATION – MARGIN PRESSURE, SET in SECTION 4 of the SERVICE MANUAL Refer to the appropriate sections of the SERVICE MANUAL, BOOM, SWING or TRACK DRIVE to set the flow (function speed) rates.

Controls and Operation

SPECIAL OPERATING INSTRUCTIONS FOR ER BOOM SYSTEM (OPTIONAL)

1. All logging and 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 MOVING TREES and FELLING TREES in SECTION 1 for additional safety information.

OPERATING THE MAIN BOOM IN THIS ZONE WITH A FULL LOAD WILL NOT ALLOW THE HORIZONTAL REACH MOTION TO PERFORM AS IT SHOULD WITHOUTASSISTANCE FROM THE RIGHT JOYSTICK

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

S860C-005

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.

TIGERCAT FLUID ANALYSIS PROGRAM Using the Tigercat Advanced Fluid 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 fluid 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 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 fluid 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 Fluid Analysis Program for all major machine components including Engines, Hydraulic Circuits, Axles, Final Drives, Gearboxes, etc.

Lubrication and Maintenance TIGERCAT FLUID ANALYSIS KITS

Tigercat S855D/LS855D Shovel Logger HYDRAULIC OIL SAMPLES

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

The accuracy of the lab analysis results is very dependent on the quality of the fluid sample taken.

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

B

A Hydraulic Sample Valve B Return Manifold

• 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.

• Purge the bleed hose before taking a representative oil sample. Drain a minimum of 90 – 120 ml (3 – 4 oz) of oil into a separate container and discard this oil using approved recycling methods.

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

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

A

800407

• Remove the bleed hose and 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.

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

• To obtain a representative oil sample, the oil must be warm and must not have settled (within 30 minutes of shutdown).

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

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

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

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

Lubrication and Maintenance

GENERAL

• 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.

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

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

• Clean around fill caps before checking or adding fluids.

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

• Clean up all spills immediately.

• Release pressure in hydraulic tank before breaking a connection. For machines with pressurized tanks.

• Have a fire extinguisher at hand.

• Use clean oil and containers.

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

• Drain dirty oil while still warm.

• Install door safety struts when working on machine.

• Do not exceed recommended fluid levels.

• Clean fire suppression system sensors.

• 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.

CHECK EMERGENCY EXITS, MONTHLY: • Two alternate exit routes are provided: side door emergency exit and roof escape hatch/emergency exit. These are only to be used if the front door cannot be opened.

• 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 WELDING, PRIOR TO in SECTION 1.

• It is therefore essential 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 for checking procedure.

• 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.

FIRE PREVENTION

IMPORTANT!

Maintaining your machine properly will greatly extend its life and reduce your operating costs.

PRESSURIZED HYDRAULIC TANK

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.

845C-097 845C-001

B

Before servicing the hydraulic system, open the air vent valve (A) to release air pressure from the hydraulic oil tank.

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.

Air vent valve is open when handle is parallel to valve.

Air vent valve is closed when handle is perpendicular to valve (shown).

After service is complete, close the air vent valve and add air pressure to the hydraulic tank using the Schrader valve (B). Make sure the air is clean and dry. Do not exceed 34.5 kPa (5 psi).

Refer to HYDRAULIC TANK PRESSURIZATION INSTRUCTIONS in THIS SECTION for details.

SCHEDULED MAINTENANCE For service and replacement intervals see SERVICE AND LUBRICATION SCHEDULE in THIS SECTION.

FREQUENTLY • Check for water in the fuel filter bowl or pre-filter.

• Visual engine check.

• Check engine cooling air intake enclosure screens for possible restriction.

• In broad leaf applications it may be necessary to reverse the cooling fan as frequently as every 10 minutes.

• Check for debris, snow and ice buildup on emergency exits and remove accumulation immediately.

• ER Boom system: Periodically, the hoist boom must be lifted up as far as it will go and then lowered to operating height in an area free from overhead obstructions in order to circulate hydraulic oil from the cylinders back through the cooler and filters. This oil does not circulate through the cooler or filters during normal horizontal motion and the oil does not get completely changed during normal vertical motion, so it is important that this procedure be followed at least once every hour.

ER BOOM SYSTEM

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

WARNING

860CS-008

This machine is 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 hoist and stick cylinders circuits are connected hydraulically. Thus, disconnecting a hydraulic line to a boom cylinder may cause either boom to move unexpectedly. The booms 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 booms and attachment.

Ensure the attachment 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.

A

B

Parking the Boom A Stick Cylinder Fully Extended B Hoist Cylinders Fully Retracted

1. The machine is parked on level ground with the heel of the attachment fully supported on the ground.

2. The stick cylinders are fully extended or the hoist cylinders fully retracted.

For additional safety precautions refer to ER BOOM SYSTEM PRECAUTIONS in SECTION 1.

NOTE: Because of the hydraulic connection between the hoist and stick cylinders, the hoist cylinders can overpower the stick cylinders under certain conditions, causing the stick boom to move unexpectedly. This most often occurs when setting the hoist boom UP relief valve, causing the stick cylinders 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 there is sufficient overhead clearance for the attachment to rise before making any adjustments.

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

Pay attention to the following when servicing the ER Boom System. Certain hydraulic circuits on this machine are inter-connected in order to provide level head-travel and to recirculate hydraulic oil to reduce heat generation and fuel consumption. As a result, disconnecting hydraulic lines from one cylinder may release pressure in a different cylinder at the same time. Before attempting to disconnect hydraulic hoses or perform work on the boom system, ensure that:

IMPORTANT! NEVER PRE-FILL HYDRAULIC FILTERS

Tigercat 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 pre-filtered before use.

Contaminated hydraulic oil 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

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 38°C (100°F)!

HYDRAULIC OIL TANK

Located at the left of the upper structure behind the cab.

The hydraulic tank (1) has a capacity of 227 L (60 US gal).

Sight gauges (2) mounted on the rear of the tank accessible through the left side door indicate the level of the hydraulic oil in the hydraulic tank.

Incorporated into the base of the top gauge is a low level switch connected to the MD3 computer.

An Alert message is displayed and the hydraulic oil level icon displays in YELLOW when the oil level falls to this point. The master alarm and alarm light will sound and flash three times.

A second oil level sight gauge located in a LOWER position on the tank than the first sight gauge also incorporates a low level switch connected to the MD3 computer. A Critical message is displayed and the hydraulic oil level icon displays in RED if there is a further loss of oil down to this point.

The master alarm and alarm light will sound and flash continuously. STOP the vehicle, check for leaks and fix if needed, refill hydraulic oil tank to suggested level.

Keep the hydraulic oil level to within 50 cm (2 in) of the high mark. A low hydraulic oil level can result in severe damage to pumps.

A temperature sender (4) mounted on the filter side of the tank activates the temperature gauge on the MD3 computer. The hydraulic oil temperature icon displays blue when cold and changes to white in normal operating temperature. should the temperature rise above normal the icon changes to yellow.

Before servicing hydraulic system, release air pressure from tank using air vent valve.

Releasing hydraulic tank pressure in the event of a hose breakage may reduce oil loss. To release pressure from the hydraulic tank: FILTER BREATHER

A critical message is displayed when the oil temperature gauge needle enters the red zone and the icon changes to red. Stop the vehicle and resolve the cause of the fault.

PRESSURE GAUGE 5 PSI MAX(34.5 KPA)

SCHRADER VALVE ADD 34.5 KPA (5 PSI) AIR PRESSURE TO PRESSURIZE TANK AFTER SERVICE IS COMPLETED H845C-59

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.

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).

NOTE: Changing strainers, 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 entrained air to escape from the oil prior to applying working pressures to the pumps.

VENTING AIR FROM HYDRAULIC SYSTEM VENT AIR FROM FITTING

NOTE: When refilling the hydraulic system, vent pumps, motors and valves of air by opening a plug or hose fitting located near or on top of the pumps, motors and valves until oil free of air is seen flowing out of the plug or hose fitting. 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: Check all hydraulic system components especially cooling fan for proper operation after hydraulic oil has been replaced.

One 125 A, one 150 A and three 60 A fuses are installed in the Fuse and Relay Rear Panel ahead of the system circuit fuses and are there to prevent major damage to the electrical systems of the machine in the event of a short circuit in any of the main battery feed lines.

Each circuit on the machine is further protected against current overload by individual circuit fuses. The circuit fuses on the Fuse, Relay and Electrical Panel in Cab protect the cab electrical components.

The fuses in the Fuse and Relay Rear Panel protect the circuits for the work lights, engine ECU, engine enclosure power roof and many other machine operating circuits. Refer to the label on the previous page for specific fuse designation and location.

A 60 A fuse located in the battery compartment provides unswitched power for dome lights and service lights.

A 10 A in-line fuse protects the fire suppression system when a fire suppression system is installed. This fuse is located in the fire suppression power lead from the battery.

If a fuse “blows” it should be replaced with a fuse of the same amperage rating. If the fuse “blows” again, the circuit in question must be inspected for possible short circuit.

AIR INTAKE SYSTEM

AIR FILTER ELEMENTS

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

To ensure maximum engine protection, it is important 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 How it works: 1. Air enters the underside of the dome through screened louvers, which prevents clogging by blocking any particles larger than the ejection slot from entering the unit.

2. Curved particle accelerator blades slam air and dirt up against the sidewall.

3. Blades along the interior surface move heavier-than-air debris towards the ejection slot.

4. Clean air continues to swirl down into the engine air inlet pipe.

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 daily to make sure that foreign materials have not plugged the intake area or the exhaust port area of the precleaner.

Filter elements increase in dust cleaning efficiency as dust builds up on the media. Looks can be deceiving. A filter that looks dirty is actually more efficient than one that is clean. A filter with dust build up on the media reaches nearly 100% dust cleaning efficiency. Only when a filter is so clogged with dirt that air restriction goes beyond engine manufacturer's guidelines, should a filter be replaced.

NOTE: This does not apply to 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.

3.75

Lubrication and Maintenance

Tigercat S855D/LS855D Shovel Logger

IMPORTANT STEPS TO FOLLOW WHEN CHANGING FILTER ELEMENTS

AIR CLEANER UNLOADER VALVE

• Release the cover latch gently to reduce the amount of dust dislodged.

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

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

• Clean the inside of the outlet tube.

• 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.

5. Inspect the new filter for damage.

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

7. Inspect connections and ducts for air tight fit.

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

UNLOADER VALVE 855D-028

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 ⅓ of full throttle. When operating in high dust conditions this valve should be checked and squeezed frequently to release dust buildup.

Lubrication and Maintenance

INTAKE TUBING AND JOINTS Inspect the intake connectors for cracked hoses, loose clamps, or punctures which can allow dirt and debris to enter the engine. Tighten or replace parts as necessary to make sure the air intake system does not leak. Check all hanger bracket hardware and repair or replace immediately.

Replace all air intake rubber connector components every 2000 hours. High temperatures in this area can cause the rubber to harden and crack.

NOTE: high-temperature silicone connectors do not need to be replaced unless they are damaged.

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

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

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

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

IMPORTANT !

The engine should not idle longer than one hour.

Damage to the emission control system will result.

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

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

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

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

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

L M N O P Q R S T U

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

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

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

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

Finally the high efficiency catalytic converter incorporates a Clean Up Catalyst (CUC) which reduces any excess ammonia (NH3) which may result from the SCR process.

CATALYTIC CONVERTER

HUMIDITY AND TEMPERATURE SENSOR

A

620E-089 855D-048

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

A Catalytic Converter

The catalytic converter is located above the engine.

Chemical reactions inside the catalytic converter reduce nitrogen oxides (NOX) in the exhaust gas.

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

TEMPERATURE SENSORS

The first phase of the SCR process takes place between the DOC and the SCR. High temperature exhaust gas evaporates the DEF solution instantly and, by hydrolysis, converts it into ammonia (2NH3) and carbon dioxide (CO2).

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

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

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

620E-087

Temperature sensors are mounted at the inlet of the diesel oxidation catalyst, the inlet of the catalytic converter and the outlet of the catalytic converter. These three sensors send exhaust temperature signals to the DENOX 2.2 control system. The control system uses this information to calculate the amount of DEF to be injected into the system.

NOTE: All three temperature sensors are identical, however location should be noted for analysis purposes when replacing a temperature sensor.

The NH3 sensor is mounted at the outlet of the catalytic converter. The NH3 sensors detect and send information about the NH3 levels in the exhaust. This information is used to calculate the amount of DEF to be injected into the system and to monitor DOC/SCR aftertreatment system operation.

Refer to APPROVED ANTI-SEIZE PASTES FOR EXHAUST/AFTERTREATMENT SENSORS in THIS SECTION.

620E-088

A Electronic Control Unit B Sensor

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

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

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

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

Use of non-approved compounds can affect the operation of the NOX and NH3 sensors and cause a malfunction of the aftertreatment system. This may result in poisoning of the SCR catalyst and require replacement of expensive aftertreatment system components.

3.98

Tigercat S855D/LS855D Shovel Logger APPROVED ANTI-SEIZE PASTES FOR EXHAUST/AFTERTREATMENT SENSORS If replacement of these components is necessary in the field, NOx sensors and NH3 sensors are pre-coated at the factory with the required anti-seize. The application of anti-seize should not be required.

In the event Anti-Seize must be re-applied, only the following approved products should be used: • NOx sensors – Weicon® high tech anti-seize only • NH3 sensor – Loctite® X203 dry film moly anti-seize IMPORTANT! When checking or replacing any sensor or plugs in the exhaust or the aftertreatment system, it is important to use only approved anti-seize as specified by Tigercat.

Use of non-approved compounds can affect the operation of the NOx and NH3 sensors and cause a malfunction of the aftertreatment system. This may result in poisoning of the SCR catalyst and require replacement of expensive aftertreatment system parts.

CARE OF POLYCARBONATE WINDOWS IN CAB

INSPECTION AND MAINTENANCE

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.

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

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.

• Inspect all windows daily and immediately after any impacts.

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

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

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

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

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

Windows with these defects must be replaced immediately.

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

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

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

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

RESISTANCE TO CHEMICALS

CLEANING INSTRUCTIONS

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.

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.

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

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:

• anti-freeze • benzene

• Fantastik

• brake fluid

• Formula 409

• carbon tetrachloride

• Hexcel F.O. 554

• cutting oils

• Joy

• gasoline

• Lysol

• lacquer thinner

• Mr. Clean

• toluene

• Neleco-Placer

• turpentine

• Pine-Sol

• 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 the higher the water temperature, the shorter the time before the polycarbonate is adversely affected.

Exposing polycarbonate to repeated steam cleaning 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.

• Top Job 3. Rinse the window thoroughly with lukewarm water.

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

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

Refer to WINDOWS – CARE OF POLYCARBONATE WINDOWS – RESISTANCE TO CHEMICALS for a list of chemicals which should not come into contact with polycarbonate windows.

CAUTIONS

SIDE WINDOW SCREENS

• 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.

WINDOW SCREEN HAND KNOB

• 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.

855D-031

SIDE WINDOW SCREEN

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

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:

A hand knob is provided on both the inside and the outside. By unscrewing either (not both) of these knobs, the screen will be free to swing out on the hinges. Be aware the screen will swing outwards with considerable force, if the door is open.

• 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 WINDOWS – CARE OF POLYCARBONATE WINDOWS – CLEANING INSTRUCTIONS.

All hand knobs should be hand tightened only at all times.

Lubrication and Maintenance

GRAFFITI REMOVAL For removal of paints, marking pen inks, etc., the use of Butyl Cellosolve is generally effective. The use of masking tape, adhesive tape or lint removal tools works well for lifting off old weathered paints.

To remove labels, stickers, etc., the use of kerosene, VM&P Naphtha, or petroleum spirits is generally effective. When the solvent will not penetrate sticker material, apply heat (hair dryer) to soften the adhesive and promote removal.

Refer to WINDOWS – 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.

REMOVAL OF ANTI-CORROSION SPRAY (IF APPLICABLE) Some machines, particularly machines shipped outside North America, are shipped with an optional anti-corrosion spray to protect the machine from corrosion during shipment.

This anti-corrosion spray should be removed when the machine reaches its destination as it may cause debris to stick to the treated surfaces of the machine.

The anti-corrosion can be removed with a pressure washer, a sponge and soap.

PROTECTING STEEL TRACKS

Alternate turning directions.

If you're 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.

R7150L2-7

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 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.

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 machine operators will carefully push the boom and attachment 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 structure.

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.

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.

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.

3.112

Tigercat S855D/LS855D Shovel Logger

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:

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.

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.

Configuration refers to the way your machine is equipped and is therefore something you can control. To minimize undercarriage wear on steeltrack machines, 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 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.

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.

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 washer

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 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.

Flange Port Assembly

FLANGE HEAD O-RING TAPPED HOLES

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.
