Tigercat emphasizes that the certification of approval of the TOPS, FOPS, OPS structure will become void if any such modifications take place.

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

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

ii) Approved modifications officially released by Tigercat.

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

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

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

Operator's cabs are designed to TOPS, FOPS, OPS standards so that they will withstand force and absorb energy during a tip-over (TOPS), when resisting the impact of a falling object (FOPS) and minimize the possibility of operator injury from penetrating objects (OPS). When a permanent deflection of the structure occurs, the structure can no longer provide the original designed level of protection and should be replaced.

Attempts to straighten the structure, particularly by the application of heat, can reduce still further the structures remaining capability to protect.

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

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

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

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

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

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

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

Some advice which should be observed:

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

• • •

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

•

• •

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

•

Machine should be washed completely at every major service.

•

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

• •

Check for fluid leaks, or faulty operation. Repair or replace malfunctioning parts and systems immediately.

Safety

Tigercat X870C/LX870C Feller Buncher

Approach with extreme caution any area where overhanging electrical power lines are present.

Serious injury or death by electrocution can result if the machine or any of its attachments are not kept a safe distance from these lines.

GENERAL SAFETY PRECAUTIONS continued Safety Hazards - Viton Seals O-rings and other seals manufactured of Viton material (fluorine rubber) produce a highly corrosive acid (Hydrofluoric) when subjected to temperatures above 600°F (315°C).

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

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

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

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

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

•

If these are found, Do Not Touch!!!

•

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

•

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

•

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

If the machine must be transported, make sure that it is adequately secured to the transporting vehicle. Refer to vehicle moving instructions page in SECTION 2 of the OPERATOR'S MANUAL. Stopping the engine immediately after it has been working under load can result in overheating and premature wear of the engine components. Reduce engine speed to LOW IDLE and let run for approximately 5 minutes to allow gradual dissipation of heat and also to reduce turbo speed. This will also prevent loss of coolant by after boil and possible hot spot damage to the engine.

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.

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

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

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

Shut off engine when refuelling - DO NOT refuel the engine while smoking or near open flame or sparks.

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. ALWAYS shut OFF engine before using the side door exit.

Check that no other personnel have moved into a hazardous area before starting the machine.

Sound the machine horn before starting the machine.

The operator’s seat is equipped with lap and shoulder harness belts. Use both of these restraint systems at all times when operating the machine.

3. 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.

ALWAYS shut OFF engine before using the escape hatch exit.

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

Start the engine according to the instructions in this manual. Refer to OPERATING MACHINE in SECTION 2 of the OPERATOR'S MANUAL. Never use a liquid staring aid to start an engine.

All three exits should be checked to make sure that 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 defeated.

IMPORTANT

WARNING

THIS MACHINE IS EQUIPPED WITH A COMPUTER CONTROLLED HEATING ELEMENT IN THE ENGINE INTAKE SYSTEM. STARTING FLUIDS WILL EXPLODE ON CONTACT WITH THE HEATING ELEMENT.

When travelling position 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.

WARNING

If saw guard has been installed, DO NOT REMOVE until at the cutting site. Remove guard before starting engine.

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

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

Anyone opening the door or screen and holding on to it could be pulled out of the cab and injured.

2. Maintain a safe operating distance between the machine and other personnel. Never operate the boom or attachment over the heads of bystanders.

3. Never travel near co-workers or other pieces of equipment with attachment running.

4. Do not allow people or other pieces of equipment near the harvesting operation.

1.8

Safety

Tigercat X870C/LX870C Feller Buncher OPERATING SAFETY PRECAUTIONS continued MACHINE STABILITY AND TRACTION MACHINES WITHOUT LEVELLER 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 felling head as low as possible to maintain a low center of gravity.

•

Always 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 rollover.

1.9

Safety

Tigercat X870C/LX870C Feller Buncher OPERATING SAFETY PRECAUTIONS continued MACHINE STABILITY AND TRACTION MACHINES WITH LEVELLER 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.

20°

860C-009

Whenever possible work within the normal working range of the boom system as shown in FIG. 1. Note that 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 that the stability of the machine is reduced. The risk of tipping is increased while operating in the reduced stability working range.

16° 860C-010

NORMAL WORKING RANGE OF BOOM SYSTEM

FIG. 2 UNDERCARRIAGE LEVELING ANGLES 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. To minimize the risk of tipping observe the following:

UPHILL REDUCED STABILITY WORKING RANGE

••

•

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

•

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

•

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

•

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

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

1.10

Safety

Tigercat X870C/LX870C Feller Buncher OPERATING SAFETY PRECAUTIONS continued •

NEVER travel across a STEEP slope or side hill.

•

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

Do not lift or move objects that exceed machine stability.

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

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

When crossing obstacles (boulders, stumps, ditches etc.) the machine can shift rapidly, greatly affecting the stability of the machine.

Move slowly over obstacles, and position the boom against the ground to reduce the risk of the machine shifting rapidly.

Backing over obstacles unexpectedly while traveling down a slope poses a tipping risk.

Know the path of the tracks whenever the machine is moved.

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

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

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

FELLING TREES Pieces of wood, debris from the ground and even teeth separating from the saw blade become potentially dangerous missiles when thrown from these machines.

Inspect saw teeth, tooth retaining bolts, saw disc and felling head assembly.

Ensure that all saw tooth retaining bolts are at correct torque value. Refer to attachment manual for correct values.

Replace all worn saw teeth or rotate worn teeth to align unused cutting tips.

Always replace saw tooth retaining bolts when replacing saw teeth.

Inspect saw disc for stress cracks and that saw disc does not wobble due to worn saw shaft bearings.

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.

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

Never start the machine if saw blade has missing teeth, teeth retaining bolts or a bent saw disc.

Shut down machine immediately if vibration occurs during cutting.

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.

Check that the saw discharge area is clear and undamaged.

When moving from tree to tree with the saw blade turning, take care not to make contact with other vegetation or debris.

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

Do not over load felling head.

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

Stop the saw blade before leaving the cutting area. NOTE: The saw blade will continue to free wheel for several minutes after the saw switch has been turned OFF.

Operate so that the chip discharge area of the felling head (where applicable) is not directed at people, livestock, buildings or other machines.

To stop the blade from rotating, CAREFULLY lower the saw blade onto a stump gently to prevent unnecessary loading of the saw blade, saw housing and bearings.

When cutting, properly position felling head in front of tree and have saw blade running at full rpm.

Always 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.

Always travel with felling head as close to the ground as possible, never elevate the felling head unless necessary.

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

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

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

• Seek professional medical attention immediately.

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

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

Always wear thick protective gloves.

• Be sure to wear safety goggles for eye protection.

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

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

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.

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

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

•

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

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

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

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

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

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

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

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

Safety

Tigercat X870C/LX870C Feller Buncher SERVICING SAFETY PRECAUTIONS continued GREASE INJECTION INJURY WHEN USING PNEUMATIC GREASE GUNS Pneumatic grease guns can deliver grease at pressures from 17 - 400 Bar (246 - 5801 psi). It takes less than 7 Bar (100 psi) to inject a substance through human skin.

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

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

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

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

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

•

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

•

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

•

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

•

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

•

Remove dirt and grease from grease fittings prior to greasing.

•

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

•

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

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

FIRE PREVENTION

5. Inspect the machine regularly for any signs of diesel fuel or hydraulic system leakage.

Check for worn or eroded fuel or hydraulic lines before starting up any equipment.

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

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

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

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

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

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

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

1.21

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

9. Inspect the exhaust system daily for any signs of leakage. Check for worn, cracked, broken or damaged pipes or muffler. Also check for missing or damaged bolts or clamps. Should any exhaust leaks or defective parts be found, repairs must be made immediately. Engine exhaust leaks can cause fires. Do not operate the machine until the exhaust leak is repaired.

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

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

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

Safety

Tigercat X870C/LX870C Feller Buncher DRY CHEMICAL CLEANUP PROCEDURES

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

Both ABC dry chemical fire extinguishers and fire suppression systems discharge a chemical powder to extinguish the fire. The chemical makeup and the small particle size of the powder as well as the force of the discharge all contribute to the fire fighting capability. These same characteristics also permit the powder to penetrate into and fully cover all components in the vicinity of the discharge.

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

The caked dry chemical when exposed to moisture is also mildly acidic. Therefore when the break down procedure has been completed, follow this immediately with the neutralizing procedure as described in step 2.

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

Workers performing this work should wear protective clothing, safety goggles and a fine particle dust mask to minimize their personal exposure to the dry chemical powder.

Ensure that all electrical systems have been completely de-energized prior to any cleanup.

1. In areas of the machine that remained cool and dry during the fire, the dry chemical will stay in powder form.

Be certain to clean these areas immediately to prevent any settled residual powder from coming into contact with moisture whether through direct contact or humidity in the air.

Remove the powder residue by blowing off with air, sweeping, dusting or vacuuming using a HEPA filter capable of trapping the small dry chemical particles. Then wipe all surfaces with a damp cloth.

2. In areas exposed to moisture, the dry chemical powder will combine with water to form a paste that is mildly acidic. Note that all surfaces covered by this dry chemical paste including electrical contacts are vulnerable to corrosive attack.

To neutralize the acidic paste on large surfaces, spray or wash these areas with a mixture of 3 parts hot water to 1 part baking soda. Allow this mixture to stand for several minutes before rinsing with warm water. Wash the area with a mild soap and water solution.

Rinse thoroughly with water. Blow-dry to remove all residual water.

Cleaning of electrical contacts should be done using an electrical contact cleaner that has no flash or fire point and is non-corrosive and nonconductive such as CRC Contact Cleaner 2000.

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

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

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

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

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

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

THE DANGERS

There are at least these means by which a rotating disc saw can cause harm by throwing: • The normal throwing of chips from the cut.

• Soil particles are thrown from the ground.

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

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

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

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

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

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

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

THROW ANGLE

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

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

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

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

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

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

FIGURE 6: ADDITIONAL OPENING IN THE HOUSING SKIRT.

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

Each figure shows a shaded area where normally tangentially thrown material can escape from the saw housing. Deflected and dropped chips escaping below the bottom edge of the housing skirt are not included. The areas and angles are not exact but do show that one head can be different from another.

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

Recognizing the Dangers While it may appear that these illustrated danger areas can be visually recognized on the job by observing how far chips fly during a cut, that is only true for chips and other light weight materials.

Metal parts and wooden spears can be thrown to surprisingly greater distances. Even distant personnel on the ground, in other vehicles, or in buildings are at risk if the throw is in their direction.

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

Throw distance The throw distance for metal pieces and stones, can be many times the distance shown by the pattern for chips. More testing and data collection is needed to pin down a “safe distance” but if someone or something is in a place that can be seen by the operator and in the throw direction of a high speed disc saw, then the operation is not safe regardless of the distance.

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

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

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

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

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

Throwing long wood pieces Dangers from throws of long wood pieces are illustrated in figures 8 to 11. Tests and experience have shown that when a high speed rotating saw is applied to a loose piece of wood, the wood is either blown or pushed away, without a throw. If the wood is held firmly in all directions and the saw advanced into it at any feed speed, cutting will take place. If the wood is only held against escape from the saw radially, but not held tangentially, then the wood will be both partly cut and partly moved tangentially. In this last case tests have shown that if the piece of wood is backed-up by a solid slippery surface; and if the feed in is very fast; and if the piece of wood is long enough; then the tangential movement is a dangerous spear-like throw.

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

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

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

Figure 11 warns that blocks of wood can be tossed in any direction when improvising with a disc saw to trim over-size stumps. A long snout and a slow feed speed lessen danger during stump trimming.

A similar danger of throw may exist when clearing small brush with multiple pass cuts.

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

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

THE INGOING ENTRANCE OF THE HOUSING FOR THE SAW RIM OF TEETH SHOULD BE SMALL

THE OUTGOING OPENING IS LARGER TO ALLOW THE HOUSING TO CLEAN ITSELF AND WILL ALLOW MOST THINGS INSIDE TO BE THROWN OUT

This information is offered by Tigercat as part of interim action to make saw heads safer. It is based on what has recently been reported from the field and on tests conducted on proving grounds.

Tigercat is continuing to do design and testing of tree felling machinery towards achieving greater safety in the woods. Tigercat would be thankful for written reports describing any unsafe happenings, including near misses, in the use of felling heads and their carriers.

The following are some “SAW HEAD DON’TS” that apply particularly to throw prevention.

Do not point the throw of a disc saw head in a direction towards people, vehicles or buildings at any visible distance.

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

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

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

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

Do not over speed the blade rpm.

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

Do not neglect tooth fastening inspection, maintenance and replacement.

Do not neglect to repair worn or damaged saw housings.

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

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

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

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

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

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

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

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

Do not select and operate heads that throw rearward.

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

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

FORWARD CONTROL PANEL

CONTROL PANEL 2. SWING BRAKE - SWITCH WITH LIGHT

1. ANTI-STALL - SWITCH WITH LIGHT This is a two position switch labelled ON /OFF. The light in the switch will come ON when the switch is in the ON position.

This switch turns on an electronic load control system for the main pump which prevents overloading of the engine by the main pump when several main pump high load functions are in use at the same time. It should be in the ON position during normal machine operation at FULL throttle and in OFF position when operating at less than FULL throttle.

IMPORTANT: It should be noted that this anti-stall system will only allow full main pump flow with the engine running at speeds above 1700 RPM. NOTE: The anti-stall feature does not manage or control the track pumps, saw pump, wrist/clamps pump, charge pump or fan pump. If any combination of these functions generate high enough loads, the engine could begin to stall, at this point the operator must back off manually on these functions to reduce the load on the engine.

If BOOM or SWING functions slow down or stop, check to ensure that the engine speed is above the required level listed above for your machine’s engine.

If engine stalling occurs, check: (a) The ANTI-STALL switch is in the ON position. (b) The 10 amp fuse located on the cab fuse and relay panel.

This fuse is labelled A/C HEAT COMBO UNIT RELAY IGNITION AND FUNCTION PANELS. (c) Malfunction of the anti-stall system.

5. IGNITION KEY SWITCH This is a three-position switch labelled OFF/RUN/ START. OFF Position - All electrical power through the ignition switch is turned “OFF” RUN Position - Connects the battery to all functions. Used for normal machine operation.

START Position - Connects the battery to the start relay to start the engine. NOTE: The PILOT SYSTEM must be OFF to start the engine. To deactivate the pilot system push the large pilot off switch button DOWN (item 9, on the rear control panel).

It is most important that the IDLE and FULL RPMs. of the engine be correct at all times: IDLE

900 to 950 RPM (No Load)

FULL

1830 to 1850 RPM max (No Load)

RATED WORKING 1800 RPM NOTE: At start-up the engine will always default to IDLE. These speeds are with the hydraulic and engine oil at normal operating temperatures and no functions activated and without pilot system engaged. These speeds are pre-set into the engine CPU (computer) and cannot be adjusted without the proper electronic equipment programming software.

Check engine speed regularly with engine diagnostics module.

WARNING: Under no circumstances allow the FULL throttle engine speed to vary from the recommended settings; particularly faster, this could cause serious damage to the pumps.

WARNING WARNING Never use a liquid staring aid to start an engine.

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

In this case press the PILOT RESET button and turn the saw switch OFF and then ON.

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

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

It should be noted that the available torque when travelling at maximum speed is only half of that in LOW. The DRIVE position will provide a faster travel speed range but with a lower driving force.

However, when the machine encounters tougher terrain conditions, e.g. stumps, soft ground or slopes etc., the drive system will automatically adjust* to a slower travel speed/ higher torque range. *This amount of adjustment can be anywhere from a slight reduction in speed to all the way down to LOW, this will be dependant on the terrain conditions encountered.

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

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

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

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

REAR CONTROL PANEL CLEAN POSITION - Momentarily pressing the switch to the CLEAN positon will start automatic reversing the direction of fan rotation (there is no need to hold the switch down). Reverse rotation is used to clean the charge air cooler, radiator, oil cooler, A/C condenser and air intake door screens. By "reversing" the flow of the fan, air flow is propelled in the opposite direction, thereby forcing dust and debris off of the radiator. Note that the pilot system must be ON to operate the clean cycle.

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

AUTO POSITION - AUTO is the normal operating position for the fan control switch.

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

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

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

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

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

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

FULL ON (OVERRIDE) POSITION - When the switch is in the FULL ON (OVERRIDE) position, the fan control system is overridden and the fan will run at FULL speed for cooling regardless of charge air, coolant or oil temperatures. Normally the fan control switch is placed in the AUTO position for optimal cooling. The FULL ON (OVERRIDE) position is intended for use in the event of a temporary failure of the fan control.

SYSTEM CONTROL PANEL

AUTOMATIC OPERATION There are 7 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.

*NOTE:

Machines shipped to international destinations have the fire suppression system deactivated to prevent accidental discharge. The inline fuse for the power lead wire to the battery (in the battery compartment) is removed and wire tied to the fuse holder.

NOTE: A pre-delivery inspection of the fire suppression system must be carried out to ensure the system is fully operational. This involves performing all daily and weekly inspection steps.

OPTIONAL FIRE SUP. SYSTEM CYLINDER The fire suppression system installed on this machine uses a dry chemical powder which is stored in a 22.6 kg (50 lbs) pressurized cylinder. It is discharged through 8 nozzles strategically placed in the engine compartment and hydraulic areas.

2.25

Tigercat X870C/LX870C Feller Buncher

Controls and operation

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

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

RED FIRE BUTTON

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

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

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

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

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

AVOIDING DAMAGE AND FALSE DISCHARGES DURING MACHINE SERVICE:

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

860C-037

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

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

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

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

PWM OUT (PWMOUT) PWM (Pulse Width Modulation) Out is a way of producing an analog signal level with a digital output that turns on and off many times a second.

By varying the ratio between on and off time (modulation ratio or duty cycle) an output proportional to the system voltage can be obtained.

PWMOUT maintains a constant output voltage, and the output current is governed by the resistance in the circuit.

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

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

Controls and operation

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

822C-62

MODULE IS OFFLINE SYSTEM WARNING

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

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

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

CAUTION Do not make adjustments in this menu.

Machine service indicators can be affected.

620C-43

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

2.50

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

Controls and operation CHECKING LEVELLING SPEED (CYLINDER CYCLE TIMES) 1. Ensure hydraulic oil is at operating temperature.

Adjustments to the levelling system through the PROPERTIES MENU of the IQAN control system electronically adjust the performance of the levelling system to suit operating conditions .

Refer also to COMPUTER ~ (PROPERTIES) MENU OPERATION in THIS SECTION.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Located at the left of the upper frame behind the cab, the hydraulic tank (1) has a capacity of 190 L (50 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 a Low hydraulic oil warning light in the cab. The light will turn ON when the oil level falls to this point.

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. This switch will signal a buzzer in the cab to sound if there is a further loss of oil down to this point.

Always keep the hydraulic oil level up to within 50 mm (2 in) of the HIGH mark. A low hydraulic oil level can result in severe damage to pumps.

Six full flow filters (3) are connected to the hydraulic tank and mounted on filter heads with built-in bypasses. The filters are located on the right side of the hydraulic tank.

NEVER PRE-FILL HYDRAULIC FILTERS HYDRAULIC OIL FILTERS

Tigercat generally does not recommend the pre-filling of spin-on filters due to the risk of damage to the hydraulic system caused by unfiltered oil. Unfiltered oil used to pre-fill filters enters directly into the hydraulic circuit.

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

RETURN FILTERS ~ HYDRAULIC OIL The return oil entering the hydraulic tank passes through six replaceable filters mounted on filter heads beside the tank and three mesh type reusable strainers one on the end of each return tube in the reservoir.

There is a bypass valve built into each filter head preset at 1.7 Bar (25 psi). which will open in the event the elements become restricted. A 1 Bar (15 psi). filter restriction pressure switch is installed in each filter head that will turn on the FILTER BYPASS warning light in the cab before this happens.

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

Filters must be replaced at the recommended time intervals, See SECTION 3 in THIS MANUAL. Use of filters other than genuine Tigercat replacement filters is not recommended.

Avoid the risk of fire caused by debris accumulating on surfaces that may become hot during machine operation. Always use care when cleaning to ensure that debris removed from one area of the machine does not accumulate on other areas of the machine. For more information on fire prevention refer to FIRE PREVENTION in SECTION 1 of THIS MANUAL.

NOTE: The cooling assembly must be checked daily and may have to be thoroughly cleaned on a daily, weekly or monthly basis, depending on operating conditions. Use personal protective equipment (eyewear) to guard against flying debris. Use compressed air for cleaning only when the machine is cold to avoid the risk of fire caused by debris contacting hot surfaces. Care must be taken not to set the pressure too high otherwise damage to the components could result.

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

2.87

Tigercat X870C/LX870C Feller Buncher

Controls and operation OPERATING TIPS WITH LOAD SENSING

TRAVELLING (BOOM RAISED) 1. Select the appropriate drive range.

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.

Place the track switch in the LOW or DRIVE position.

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

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

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

Refer to SET MARGIN PRESSURE in SECTION 4 of the SERVICE MANUAL

3. Move throttle control to the HIGH idle position.

Refer to SET FLOW (FUNCTION SPEED) RATE in appropriate BOOM, SWING or TRACK DRIVE sections of the SERVICE MANUAL.

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

FELLING HEAD OPERATING INSTRUCTIONS AND SAFETY PRECAUTIONS 1. All tree harvesting should be carried out in LOW driving range. Refer to TRACK, LOW/ DRIVE SWITCH in THIS SECTION. 2. See appendix to SECTION 1 - USING HIGH SPEED DISC SAWS SAFELY. 3. See ORIGINAL MANUFACTURER'S FELLING HEAD MANUAL for proper operating and maintenance instructions.

2.88

Tigercat X870C/LX870C Feller Buncher SPECIAL OPERATING INSTRUCTIONS FOR ER BOOM SYSTEM (OPTIONAL) NORMAL HORIZONTAL REACH MOTION PERFORMANCE CAN BE EXPECTED IN THIS AREA

Controls and operation CARE OF THE MACHINE 1. Ensure that all fluid levels are always at the proper level. Refer to the LUBRICATION AND MAINTENANCE SCHEDULE in SECTION 3 of THIS MANUAL.

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

2. Lubricate all grease points at the required intervals as specified in the LUBRICATION AND MAINTENANCE SCHEDULE in SECTION 3 of THIS MANUAL.

••

3. Follow proper procedure for cleaning windows described in this section.

•

4. Always install roof safety strut and right side door retaining strut before working in the engine area.

5. Close and secure all doors and access panels before running the machine.

6. Ensure that the cab emergency exits are in working order by following the EMERGENCY EXIT MAINTENANCE guide in this section.

7. Do not allow branches, twigs, leaves or pine needles to build up around radiator intake doors or anywhere else on the machine.

Clean as operating conditions warrant but at least once a day all debris must be removed from the machine interior.

860C-003

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.

8. Do not apply load to a cold engine.

9. Always harvest trees in LOW driving range.

10. Never park machine with felling head raised off the ground. Be sure that the felling head is resting on the ground before servicing or parking the machine. Refer to PARKING BOOM in SECTION 1 of THIS MANUAL for complete instructions.

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.

11. SAFETY FIRST! Follow all safety rules and regulations as outlined in SECTION 1 of THIS MANUAL.

Tigercat X870C/LX870C Feller Buncher CLEANING INSTRUCTIONS FOR LEXAN WINDOWS

Controls and operation GRAFFITI REMOVAL (A) Butyl Cellosolve (For removal of paints, marking pen inks, etc.) The use of masking tape, adhesive tape or lint removal tools works well for lifting off old weathered paints.

NOTE: Windows made of LEXAN are heat stamped LEXAN or LEXGARD to indicate they are LEXAN windows.

1. Rinse with lukewarm water.

(B) 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. GASOLINE SHOULD NOT BE USED.

2. Using a soft cloth or sponge, gently wash the sheet with a mild solution of soap or detergent and lukewarm water. DO NOT scrub or use brushes or squeegees.

3. Rinse with clean lukewarm water.

4. Dry thoroughly with a chamois or moist cellulose sponge to prevent water spotting.

REMOVAL OF ANTI-CORROSION SPRAY (IF APPLICABLE)

To remove wet paint, glazing compound or grease, rub lightly (not in direct sunlight) with a good grade of VM&P naphtha, isopropyl alcohol or butyl cellosolve (2-Butoxy Ethanol), then wash and rinse thoroughly. DO NOT USE GASOLINE. Gasoline or oil will cause uncoated LEXAN to become opaque. MARGARD coated lexan will start to become opaque around the edges and creep in.

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 it’s destination as is may cause debris to stick to the treated surfaces of the machine.

REMOVING HAIRLINE SCRATCHES

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

Scratches and minor abrasions can be removed or minimized by using a mild automobile polish.

Three such products that tend to polish and fill scratches are Johnson Paste Wax, Novus Plastic Polish #1 & #2, and Mirror Glaze Plastic Polish. It is suggested that a test be made on a sample of LEXAN sheet with the product selected and that the polish manufactures instructions be followed.

SOME IMPORTANT DON’TS DO NOT use abrasive or highly alkaline cleaners on LEXAN sheet products.

Never scrape LEXAN sheet products with squeegees, razor blades or other sharp instruments.

Benzene, gasoline, oil, acetone or carbon tetrachloride should never be used on LEXAN sheet products. DO NOT clean LEXAN sheet products in hot sun or at elevated temperatures.

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

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

Detect problems early before they become major catastrophic failures.

•

Better ability to schedule downtime and forecast cost of repairs.

•

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

•

Increase used equipment value by providing proof of proper maintenance.

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

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

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

HYDRAULIC SAMPLE VALVE

•• H855C-31

Hydraulic Oil Samples:

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

Collection of clean oil samples that are representative of the main body of oil are essential if meaningful lab results are to be obtained.

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

•

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

•

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

•

Do not allow any airborne dirt, etc. to enter the sample bottle.

•

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

HYDRAULIC OIL

•

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

•

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

•

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

Gearbox Samples:

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

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

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

3.4

•

These samples can be taken during the oil change process.

•

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

•

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

•

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

Lubrication and Maintenance

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

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

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

Always have a fire extinguisher at hand.

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

Clean up all spills immediately.

Always use clean oil and containers.

Drain dirty oil while still warm.

Always install door safety struts when working on machine.

Do not exceed recommended fluid levels.

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.

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

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

Clean fire suppression system sensors.

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

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

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

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

Clean away all branches, bark and chips.

Clean up all traces of oil to avoid fires.

Inspect the EXHAUST BLANKET and EXHAUST SYSTEM DAILY for any signs of LEAKAGE. Check for worn, cracked, broken, or damaged pipes or muffler. Also check for missing or damaged bolts or clamps. Should any exhaust leaks or defective parts be found, repairs must be made immediately. Engine exhaust leaks can cause fires, DO NOT OPERATE the machine until the exhaust leak is repaired.

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

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

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

CAUTION

FILTER BREATHER

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.

MANIFOLD

•• •

••

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.

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

WARNING

STICK CYLINDERS FULLY EXTENDED

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

• TIP OF STICK BOOM FULLY SUPPORTED

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

860C-001

ER. BOOM SYSTEM. FIG.1

HOIST CYLINDER FULLY RETRACTED

(a) The machine is parked on level ground with the head sitting flat on the ground. (b) The stick cylinders are fully extended (fig. 1) or the hoist cylinder fully collapsed (fig. 2). (c) The tip of the stick boom supported .

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

Tigercat X870C/LX870C Feller Buncher FILTERS - REMOVE AND REPLACE

Lubrication and Maintenance IMPORTANT

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

IMPORTANT Refer to the appropriate engine manufacturers operation and maintenance manual for correct procedures and time intervals when servicing the engine coolant, oil and fuel filters.

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

•

•• WATER-IN-FUEL SENSOR CONNECTION

Tier III engines typically use filters with a very fine micron rating. If the fuel supply is dirty, the fuel filter must be replaced more frequently than recommended in the owner’s manual. Operating the machine with a clogged fuel filter will result in low engine power. It is also recommended that the fuel/water separator bowl be drained daily.

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

SECONDARY FUEL FILTER/ WATER SEPARATOR

PRIMARY FUEL FILTER

Filters that are an integral part of the engine (fuel and lubricating oil) should be serviced and replaced according to the engine manufacturer’s operation and maintenance manual.

CHARGE PILOT FILTER

There is a medium pressure charge pilot filter mounted to the base of the charge/pilot/filter manifold. This filter receives hydraulic oil from the charge pump. The charge pump supplies pilot oil via the filter and the charge/pilot/filter manifold to the pilot system.

Mounted on top of the manifold is a clog indicator.

Under normal operating conditions (or when the hydraulic system is shut down) the indicator will show GREEN. When a pressure differential of 50 psi exists across the filter, the indicator will show RED, indicating a clogged filter.

This condition could happen during cold start-ups, but as the oil warms up the indicator will automatically reset to GREEN. A “Clogged” condition will result in low pilot pressure. If a loss of controls or slow response occurs, filter element may need to be changed.

For service and replacement intervals see SERVICE AND LUBRICATION CHART in THIS SECTION. Changing the filter: 1. Park machine on flat ground with with upper structure level, the felling head resting on the ground and stop engine.

2. Turn BATTERY DISCONNECT SWITCH to ‘OFF’ position. Always install a “DO NOT START ENGINE” sign on the operator’s cab door and in the engine compartment when making repairs to the machine.

Lubrication and Maintenance 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 other primary element change.

SAFETY ELEMENT

IMPORTANT STEPS TO FOLLOW WHEN CHANGING FILTER ELEMENTS 1. Release the cover latch gently to reduce the amount of dust dislodged.

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

• AIR CLEANER .PLT

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

PRIMARY ELEMENT

4. Always clean the inside of the outlet tube.

AIR FILTER ELEMENTS

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

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

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

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

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

6. Inspect the new filter for damage.

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

8. Check connections and ducts for air tight fit.

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

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

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

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

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

Assemb que Assemblly Tor orque The four-bolt port is simply a circular opening (flow passage) surrounded by four tapped holes in a certain pattern for acceptance of the flange clamping bolts.

The flat surface of the port compresses the O-ring contained in the groove in the flange head when the clamp bolts are torqued. In some instances, the groove is in the port and not in the flange head. The bolts, through the clamp halves, clamp down the flange head on to the flat surface of the port compressing and trapping the O-ring in the groove and leaving no gap for it to extrude under pressure. The hydraulic pressure is thus sealed by the compressed O-ring as long as the bolts are tightened enough to maintain solid metal to metal contact between the flange head at the outside diameter of the O-ring and the top of the port.

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

• Four bolts and washer

BOLTS FLANGE CLAMP

Flange Port Assembly FLANGE HEAD

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.
