Tigercat 860/870/L870 Feller Buncher

Safety Do not operate the machine with any defective or inoperable components.

GENERAL SAFETY PRECAUTIONS CONTINUED

Check all fluid levels.

When mounting or dismounting the machine always use the 3 point technique; use one hand with 2 feet or 2 hands with 1 foot.

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

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

Avoid mounting or dismounting the machine in areas with slippery surfaces. If this is not possible, clean up or cover slippery surfaces with a non-slip material.

Safety Hazards - Viton Seals O-rings and other seals manufactured of Viton material (fluofine rubber) produce a highly corrosive acid (Hydofluoric) when subjected to temperatures above. 600°f (315°c).

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

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

•

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 fluro-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.

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.

Check windows and door guards for damage.

NOTE:

Check protective windows for cracks, a damaged window has reduced strength to stop flying objects.

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

Safety

FIRE PREVENTION

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

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 damage to a minimum.

1. Maintain a CHARGED fire extinguisher on the machine at all times and KNOW HOW TO USE IT. 2. Inspect the machine for any signs of fuel or hydraulic system leakage and check for worn or eroded fuel or hydraulic lines before starting up any equipment.

Dispose of fluids properly.

Do not pour fluids into the ground, stream, pond or lake.

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

Read, understand and follow with all operating safety precautions specified by felling head manufacturer.

3. Remove debris and blow out dust regularly from the air intake doors, engine radiator, hydraulic oil cooler and A/C condenser core to prevent overheating of the engine and hydraulics. Refer to CLEANING A/C CONDENSER, OIL COOLER AND RADIATOR in SECTION 2 of the OPERATOR’S MANUAL. 4. Blow off all debris and dust 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 depending on logging conditions.

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 by vibration this smoldering debris 1.14

Tigercat 860/870/L870 Feller Buncher FIRE PREVENTION CONTINUED can fall into other areas of the machine and thereby spread a fire.

5. 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.

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

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

17. Use only nonflammable solutions for cleaning the machine or components.

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

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

6. AFTER transporting (trucking) a machine from one job sight to the next, open all doors and access panels and blow off any debris that could have re-positioned itself onto the engine and exhaust parts due to wind turbulance caused by the journey.

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

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

WHAT ELSE TO DO BEFORE YOU EXPERIENCE A FIRE

8. Steam clean the engine, transmission, brake, fuel and hydraulic tank compartments of all equipment at least once a month or more frequently depending on logging conditions.

•

Ensure that you are familiar with emergency procedure in the event of a fire.

•

Ensure that your fire suppression system* is charged and functional.

•

Ensure that any hand held fire extinguishers are charged and functional.

•

Ensure that any stored water systems on the machine are charged and functional.

•

Ensure that the nozzle of any hand held extinguishers available at the work site fits within the access holes in the doors of the machine.

•

Ensure that you have the proper fire extinguishers on site. Most fires involving mobile equipment will be of the A or B type.

You should have a dry chemical extinguisher rated ABC and a pressurized water extinguisher rated A.

•

Prevent the fire from happening by ensuring that the machine is cleaned regularly and all systems are well maintained.

9. Be cautious when smoking. An open flame, a lighted cigarette, etc., should not be permitted around any vehicle, especially during fuelling operations and/or when the fuel system is open to the atmosphere, and/or when servicing batteries.

10. Shut down equipment immediately when a problem is suspected or smoke is detected.

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

12. Turn the battery disconnect switch to OFF at shut down to avoid loss by electrical short.

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

14. Once a fire has started on a machine hoses will quickly burn through causing pressurized fluids (diesel fuel, hydraulic oil, etc.) to fuel the fire. NEVER leave the machine parked with booms or arches suspended off the ground, as they will inject hydraulic oil into the fire if a supporting hose burns through.

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

Safety

FIRE PREVENTION CONTINUED WHAT TO DO IN CASE OF A MACHINE FIRE •

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.

•

If the machine is in a dangerous position, attempt to move to a safe position. Lower working attachment to the ground.

•

Shut the engine off.

•

Activate the fire suppression system*

•

Radio or call for help (as appropriate).

•

Exit the machine taking fire extinguisher or water hose (if applicable) with you.

•

If you can safely open the access panels to the machine, in the area of the fire, do so.

•

If you can safely do so, attempt to extinguish the fire.

•

A dry chemical fire extinguisher should be used first, if available.

•

Use the PASS method with most extinguishers.

•

Pull the pin. This will allow you to discharge the extinguisher.

•

Aim at the base of the fire. If you aim at the flames (which is frequently the temptation), the extinguishing agent will fly right through and do no good. You want to hit the fuel.

•

•

Squeeze the top handle or lever. This depresses a button that releases the pressurized extinguishing agent in the extinguisher.

Sweep from side to side until the fire is completely out. Once the fire is out, keep an eye on the area in case it re-ignites.

•

Place the nozzle of the fire extinguisher into the appropriate fire extinguisher access hole and discharge the extinguisher.

•

Failing all attempts to access the machine compartment, attempt to discharge the extinguisher through the mesh or any available openings on the machine.

20229A

TYPICAL FIRE EXTINGUISHER ACCESS HOLE

•

Use the pressurized water hose supplied with the machine (if applicable) or a pressurized water extinguisher (if available) after the discharge of a dry chemical extinguisher or suppression system* to remove heat build up from the area. A fire suppressed by a dry chemical powder may re-ignite with the latent heat of any debris in the area.

•

Remain with the machine until help arrives to ensure that the fire does not re-ignite.

•

Ensure that the machine and all components have cooled down sufficiently after a fire has occurred. Beware of the possibility of coolant or hydraulic hoses rupturing after a fire spraying hot oil or coolant which may result in severe burns.

WHAT TO DO AFTER A FIRE •

Notify your equipment dealer and or Tigercat Industries Inc. by completing an incident report, Tigercat form number 5101.

•

Ensure that the cause of the fire is determined and all appropriate repairs are completed before returning the machine to work.

•

Ensure that the fire suppression system* is properly serviced and returned to a functional state (if applicable).

•

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

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

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.

The module includes a two line eight character backlit LCD, displaying data in either imperial or metric units.

20. TACHOMETER This meter indicates the engine speed.

Refer to THROTTLE CONTROL in THIS SECTION for engine speed information transmitted by the MDDM diagnostics module.

Two push button switches (UP and DOWN) are used to scroll through the parameter list or main menu (see below). Two LEDs (amber and red) are used to draw attention to active fault messages received by the module.

21. ENGINE OIL PRESSURE - gauge

To read any of the engine parameters press either the UP or DOWN arrows until the display shows the desired information.

This gauge displays information transmitted by the MDDM diagnostics module in the traditional analog format.

ACTIVE ENGINE SERVICE CODES

The engine oil pressure should be greatest after starting a cold engine. Check oil pressure as soon as engine starts. If gauge does not rise above minimum oil pressure of 15 psi within 5 seconds, stop engine and determine cause.

When a fault occurs the display will show the message "SrvcCode" every five seconds interrupting the currently displayed parameter.

In addition the amber LED will start to flash during active service code faults and the red LED will be ON during shut-down faults.

These warnings will continue until the fault is corrected.

When the engine is running at full load rated speed, using SAE 10W30 oil and engine oil at normal operating temperature, the normal operating oil pressure should be between 40 and 70 psi. If the oil pressure gauge registers less than stated above at high idle, check the engine oil level. If pressure drops below 15 psi., shut the machine down immediately.

To view the active service codes, select the service code sub-menu by pressing the UP or DOWN arrows until the display shows the message "SrvcCode". Press BOTH the UP and DOWN arrows SIMULTANEOUSLY to access the sub-menu. If the service codes are not available, the display will show the message "SrvcCode - No Code".

NOTE: At low engine speeds the oil pressure will be low. This is not an abnormal condition but must be closely monitored.

34. ANTI-STALL - switch with light This is a two position switch used to turn on the electronic load control system which automatically prevents overloading of the engine when several 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: This is a two position switch; The DRIVE position provides infinitely variable travel speeds/torque ranges, unlike similar travel range controls on some types of construction equipment.

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

The light in the switch will come ON to indicate that the switch is ON.

It is recommended that during all harvesting functions and when travelling down slopes that the range switch be placed in the LOW position to maximize drive motor life.

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.

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.

If BOOM, SWING or TRACK DRIVE functions, (or LEVELLING functions if applicable) slow down or stop, check to ensure that the engine speed is above 1700 RPM. If engine stalling occurs, check:

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.

(a) The ANTI-STALL switch is in the ON position. (b) The 2 amp. in-line fuse in the anti-stall electrical system. (c) Malfunction of the anti-stall system.

35. CIGAR/CIGARETTE LIGHTER 36. IGNITION - key switch This is a three-position switch labelled OFF/ RUN/START.

*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.

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.

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. It is not necessary to place the range switch in the LOW position.

START Position - Connects the battery to the start relay to start the engine. NOTE: The PILOT SYSTEM must be OFF to start the engine. If the engine will not start because of this, lift the LEFT arm rest to deactivate the Pilot system.

25. TRACK, LOW/DRIVE - switch with light

the HIGH and LOW speed/torque set points, relative to the terrain or load conditions.

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

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

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

It is recommended that during all harvesting functions and when travelling down slopes that the range switch be placed in the LOW position to maximize drive motor life.

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 2.24

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

Tigercat 860/870/L870 Feller Buncher 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. It is not necessary to place the range switch in the LOW position.

Controls and operation 28. CIGAR/CIGARETTE LIGHTER 29. PILOT RESET - switch, momentary With the engine running and LEFT arm rest DOWN, PRESS this momentary switch to ACTIVATE the pilot system.

26. ANTI-STALL - switch with light This is a two position switch used to turn on the electronic load control system which automatically prevents overloading of the engine when several 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.

The light in the switch will come ON to indicate that the switch is ON.

WARNING Do not, under any circumstances allow the pilot system to be re-activated without an operator in the cab.

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

IMPORTANT: It should be noted that this anti-stall system will only allow full main pump flow with the engine running at speeds above 2150 RPM.

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.

If BOOM, SWING or TRACK DRIVE functions slow down or stop, check to ensure that the engine throttle control is pulled completely out in the FULL throttle position.

START Position - Connects the battery to the start relay to start the engine. NOTE: The PILOT SYSTEM must be OFF to start the engine. If the engine will not start because of this, lift the LEFT arm rest to deactivate the Pilot system.

If engine stalling occurs, check: (a) The ANTI-STALL switch is in the ON position. (b) The in-line fuse in the anti-stall electrical system.

31. SWING BRAKE - switch with light This is a two position switch, placing this switch in the ON position will apply the swing brake and prevent the upper structure from turning. The brake is also engaged whenever the pilot system is shut off (LEFT arm rest in raised position), but as an added safety precaution, the brake should always be applied with this switch when leaving the cab.

The swing brake is a spring apply, hydraulic release, multi disc brake.

32. ETHER STARTING AID - SWITCH, MOMENTARY (OPTIONAL)

IMPORTANT: To prevent dust from being drawn into the engine, leave a can in place on the solenoid assembly. A common cause of system failure occurs because dirt was allowed into the system when changing the fuel canisters.

This is a two position momentary switch, spring return to OFF position labelled ON, OFF. IMPORTANT: To avoid damage, crank engine with starter one or two revolutions before injecting starter fluid. Inject fluid only when engine is turning. To inject starting fluid, momentarily depress the ETHER switch, using short “bursts” while cranking the engine at the same time. Stop injecting fluid after engine starts. If engine begins to die during the first few minutes, inject another “shot” of fluid.

DANGER •

•

TO INSTALL A NEW CAN OF STARTING FLUID Clean the area around the valve before removing the empty canister. Loosen the band clamp that holds the canister, unscrew the canister from the solenoid assembly and discard properly. Check the valve gasket under the canister and replace if damaged or missing, take care not to accidentally install two gaskets as this could cause leaks.

Remove the protective cap from the new canister and screw the canister (hand-tight) onto the solenoid assembly. Re-tighten the band clamp to hold the can in place.

•

When working on this starting aid system always make sure that you are in a well ventilated area, away from heat, open flames or sparks.

The Ethyl Ether used in this system is extremely flammable, toxic, harmful or fatal if swallowed. Avoid contact with skin or eyes. Do not breath the fumes.

If swallowed, DO NOT INDUCE VOMITING. Call physician immediately.

If fuel enters eyes or fumes irritate eyes, they should be washed with large amounts of clean water for 15 minutes.

FIRE SUP. SYSTEM, KIDDE , continued:

DURING SERVICE:

IMPORTANT Before servicing any part of the fire suppression system read the system manufacturer’s manual thoroughly.

PDI AND SERVICING RECEIVING A TIGERCAT MACHINE THAT HAS A FIRE SUPPRESSION SYSTEM: The machines are shipped with the fire suppression system installed but not certified.

At the time of P.D.I. the system MUST be inspected, activated and certified for use by an approved Kidde fire suppression system representative.

SERVICING A Tigercat MACHINE THAT HAS A FIRE SUPPRESSION SYSTEM INSTALLED:

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 lead to burnt wiring or an accidental discharge of the system. If any of the components have been damaged replace them immediately. 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.

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

AFTER SERVICING:

Certain steps must be followed to avoid an accidental discharge of the fire suppression system when servicing the machine.

BEFORE ANY SERVICE IS PERFORMED: 1. Remove the connector wire from the squib (at the cartridge assembly) 2. Install the grounding (shunting) spring onto the leads of the squib (inside connector) This now prevents electrical actuation of the system. The shunting device is very important to ensure that there is no discharge of static electricity that could set off the squib.

NOTE: The shunting spring must be removed before reconnecting the Squib. Connecting the Squib with the shunting spring installed will cause the Squib to fire.

3. Remove nitrogen filled cartridge from the actuator assembly and install safety cap onto cartridge.

50 LBS PRESSURIZED CYLINDER 378-16A The fire suppression system installed on this machine uses a dry chemical powder which is stored in a 50 lbs. pressurized cylinder. It is discharged through 8 nozzles strategically placed in the engine compartment and hydraulic areas.

The discharge is triggered automatically by the fire detection thermostats or manually by the operator.

To manually operate the system:

The control panel in the cab provides continuous monitoring of the system. It also, automatically actuates the suppression system when signalled by the thermostats.

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

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 actuator extends a control shaft which mechanically opens the agent cylinder valve. This releases the dry chemical in the discharge area protected by the system. At the same time the control panel will also automatically shut down the engine.

FIRE SUP. SYSTEM, AMEREX continued:

for flashbacks after system has discharged.

For none levelling machines the automatic engine shutdown feature will shutdown the engine immediately the fire suppression system is discharged. For levelling machines there will be a delay of between 10 to 15 seconds before the engine shuts down. 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.

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.

IN CASE OF FIRE: If a fire starts in any space protected by the system, DO NOT wait for the system to operate automatically. operate the system manually:

DAILY:

Before cleaning up after a discharge, read the AMEREX manual. If water mixes with the dry chemical it becomes corrosive and can seriously damage wiring connections.

Dry chemical must be vacuumed or blown off with compressed air.

AVOIDING DAMAGE AND FALSE DISCHARGES DURING MACHINE SERVICE: 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 lead to burnt wiring or 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. Cutting the wiring anywhere along the electrical circuits especially the detection circuits, will cause a false discharge.

82. ENGINE AIR PRECLEANER

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

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 check periodically to make sure that foreign materials have not plugged the intake area or the exhaust port area.

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

Refer to AIR CLEANER MAINTENANCE in THIS SECTION. 84 AIR CLEANER UNLOADER VALVE This rubber valve on the tube of the air cleaner housing should be checked before the start of 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.

Tigercat 860/870/L870 Feller Buncher TRAVELLING (BOOM RAISED) 1. Select the appropriate drive range.

Controls and operation SPECIAL OPERATING INSTRUCTIONS FOR ER BOOM SYSTEM

Place the track switch in the LOW or DRIVE position.

NORMAL HORIZONTAL REACH MOTION PERFORMANCE CAN BE EXPECTED IN THIS AREA

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.

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

••

•

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

3. Move throttle control to the HIGH idle position.

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

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

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

870B-01

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.

Refer to SET MARGIN PRESSURE in SECTION 4 of the SERVICE MANUAL Refer to SET FLOW (FUNCTION SPEED) RATE in appropriate BOOM, SWING or TRACK DRIVE sections of the SERVICE MANUAL.

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.

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.

REMOVING HAIRLINE SCRATCHES 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.

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

CAUTION ALL HANDLES, STEPS AND PLATFORMS MUST BE KEPT FREE OF GREASE, OIL, FUEL, MUD, SNOW, ICE AND FOREST DEBRIS.

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

Clean around filler caps before checking or adding fluids.

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

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

Clean up spills as soon as possible.

Always release pressure in hydraulic tank Before breaking a connection.

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

Always use clean oil and containers.

Drain dirty oil while still warm.

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

Do not exceed recommended fluid levels.

Service all hydraulic filters after the failure of a pump, motor, cylinder or valve. Failures of this nature could contaminate the entire hydraulic system.

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.

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

Clean up oil spills on walking surfaces in engine enclosure immediately.

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.

Before welding on machine, be sure the negative battery terminal is disconnected.

Before welding on machine, disconnect the multi-pin plug from the engine anti-stall controller and the two engine CPU multi-pin plugs from the left side of the engine.

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

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

Clean away all branches, bark and chips.

Clean up all traces of oil to avoid fires.

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

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.

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

Always install roof safety strut when working in engine compartment.

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

Clean fire suppression system sensors.

Tigercat 860/870L870 Feller Buncher ER BOOM SYSTEM

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.

870B-02

ER. BOOM SYSTEM. FIG.1

HOIST CYLINDER FULLY RETRACTED

•

TIP OF STICK BOOM FULLY SUPPORTED 870B-03

ER. BOOM SYSTEM. FIG.2

(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 860/870/L870 Feller Buncher LUBRICATION OF SWING DRIVE GEARBOX

Lubrication and Maintenance

UPPER GEARING LUBRICATION The swing gearbox upper gearing is lubricated by hydraulic oil which flows from the 'PB' port, one of three return ports on the clamps and wrist valve into the swing brake 'U' port on the swing drive gearbox. A 1/16 inch orifice/connector installed in the 'U' port regulates the flow of oil through the gearbox at approximately 1 GPM. Oil is returned to tank via flushing port 'T'.

LOWER BEARING LUBRICATION The cavity in the lower portion of the gearbox where the two lower bearings are housed is completely filled with grease.

PILOT PRESSURE FILTER, CLOG INDICATOR 221-15A

ON EARLIER MACHINES

FILTER CLOG INDICATOR, EARLIER MACHINES This filter incorporates a clog indicator. The clog indicator consists of a clear plastic sight glass mounted on top of the filter housing. Under normal operating conditions (or when the hydraulic system is shut down) the indicator will show GREEN. When a pressure differential of 72 psi builds up inside 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 re-set to GREEN. The indicator will not remain in the “clogged” (RED) position when the pilot system is not being used. “Clogged” condition will result in low pilot pressure. If a loss of controls or slow response occurs, filter element may need to be changed. Refer also to SECTION 5 of the SERVICE MANUAL for more information.

For service and replacement intervals see SERVICE AND LUBRICATION CHART in THIS SECTION.

HYDRAULIC FILTER SERVICING GUIDELINES

1. Park machine on level ground with felling head resting on the ground and stop engine.

2. Turn BATTERY DISCONNECT SWITCH to ‘OFF’ position.

IMPORTANT

3. Release air from the hydraulic tank by opening the AIR VENT VALVE. 4.

NEVER PRE-FILL ANY HYDRAULIC FILTERS ON 200, 700, 800 AND 1000 SERIES MACHINES NEVER PRE-FILL CHARGE PRESSURE FILTERS ON 600 SERIES SKIDDERS

A small accumulator is used in the pilot supply circuit to ensure an adequate supply of pilot control oil under all operating conditions. The accumulator will normally bleed down the pilot supply oil to zero PSI in under 30 seconds after engine shut down, but install a 0 to 1000 PSI gauge on the pilot supply circuit test port to be sure the pilot system is not under pressure before unscrewing the filter bowl.

Tigercat generally does not recommend the prefilling of spin-on filters due to the risk of damage to the hydraulic system caused by unfiltered oil.

Unfiltered oil used to pre-fill filters enters directly into the hydraulic circuit. Contaminants in unfiltered oil can cause significant and costly damage to hydraulic valves, pumps and motors.

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

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

6. Place rags below to catch any spilt oil.

7. Wearing face protection (in case of an oil spray), unscrew the filter bowl from the filter head. Remove the filter element and dispose of it properly. Clean out the filter bowl before reusing it.

ALWAYS PRE-FILL DUAL HEAD HYDRAULIC FILTERS ON 600 SERIES SKIDDERS

8. Remove and discard the small o-ring from between the filter element and the filter head.

9. Check the seating area for the other o-rings and seals on the filter bowl and filter head.

Wipe clean.

Dual head hydraulic filters on 600 series skidders must always be pre-filled with clean oil as noted specifically in the manuals for each of these machines.

10. DO NOT pre-fill the filter*. Lubricate any new o-rings and seals with clean hydraulic and install the new filter element.

All 600 series hydraulic circuits direct oil from the dual head filters to the main and drive pump inlets. Air must not be allowed to enter the inlets of these pumps. Entry of air directly into pump inlets can cause significant and costly damage to pumps. In this particular case the risk of damage to pumps caused by entry of air into the circuit is considered to be greater than the risk of damage caused by unfiltered oil. Prefiltering of any hydraulic oil used to pre-fill these filters is strongly recommended to eliminate the risk of damage caused by unfiltered oil.

11. Close air vent ball valve. *Refer to HYDRAULIC FILTER SERVICING GUIDELINES.

IMPORTANT Contaminated hydraulic fluid can lead to premature failure of hydraulic components and costly repairs. Filters must be replaced at the recommended time intervals, Refer to SCHEDULED MAINTENANCE in THIS SECTION. Use of hydraulic oil filters other than the Tigercat brand could lead to severe wear and rapid failure of hydraulic system components.

AIR CLEANER UNLOADER VALVE

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

This rubber valve on the tube of the air cleaner housing should be checked before every shift (8 hrs).

If this valve is missing, damaged or has turned hard, it will cause the air cleaner to become ineffective. The valve should be replaced every 1000 Hours.

IMPROPER SERVICING Engine exposure to dust during servicing is the largest single reason for engine damage due to dust. Remove the unloader valve from the tube of the air cleaner housing. A good valve is soft and flexible.

Abrasive dust can easily enter the intake system Check and clean the valve. If it was plugged, then once the air cleaner cover and protective filter check the filter elements as they may need to be element is removed for replacement. The safety replaced as well.
