SERVICING SAFETY PRECAUTIONS

WARNING Diesel fuel or hydraulic fluid under pressure can penetrate the skin and cause serious personal injury, blindness, or death. If any fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with treating this type of injury.

Conduct maintenance inspections at least as frequently as recommended in section 3 of the operator's manual.

When servicing or repairing equipment, shut the engine down. Turn Master Disconnect switch OFF.

Never use your bare hand to check for fluid leaks.

Fluid leaks under pressure may not be visible.

When searching for leaks, wear work gloves and use a wrench or piece of wood to move hydraulic hoses. Do not grab hold of hydraulic hoses. Wear safety goggles for eye protection.

Install a “DO NOT START ENGINE” sign on the operator’s cab door and in the engine compartment when making repairs to the machine.

Pressure can be maintained in a hydraulic system long after the power source and pump have been shut down. Lower the felling head to the ground, stop engine and relieve trapped pressure (from the accumulator on later machines) by operating the joystick several times before performing work on components, or disconnecting any hoses. Also relieve pressure in the hydraulic reservoir by loosening the breather cap and waiting until the sound of escaping air stops.

Before performing maintenance or repair work on any equipment, consult the manufacturer’s instruction manual and follow recommended procedures.

The radiator and the engine cooling system should be cleaned and serviced daily to maintain moderate engine temperatures.

Prior to welding on any part of the machine, it should be cleaned and a fire extinguisher should be made available at the welding location. Care must be taken in attaching the welding machine grounding clamp so current does not pass through bearings, especially the swing bearing.

Also, disconnect the negative (-) battery cable from both batteries. This machine is equipped with an electronic horsepower limiting control. Prior to welding, the 25 pin connector should be disconnected from the black box located on the rear inside wall of the cab .

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

1.7

Tigercat 845 Feller Buncher

Safety Work in a ventilated area. If it is necessary to run an engine in an enclosed area, use an exhaust pipe extension to remove toxic exhaust fumes.

SERVICING SAFETY PRECAUTIONS continued Shut off engine. Only remove engine radiator filler cap when cool enough to touch with bare hands.

Slowly loosen cap to first stop to relieve pressure before removing completely.

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

Dispose of fluids properly.

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

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

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.

Keep your hands, feet, head, and loose clothing away from power driven parts. Tie long hair behind your head. Remove rings and other jewelry to prevent electrical shorts and entanglement in moving parts.

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

Never stand under an object supported with hydraulics. Always use safety stands or a locking device.

Before performing work under the felling head or boom, ensure they are firmly supported.

If the engine is running inside a building, ensure that sufficient ventilation is available to prevent a build-up of toxic exhaust fumes. Run the engine only when it is necessary for testing or adjustments.

Safety dislodged by vibration this smoldering debris can fall into other areas of the machine and thereby spread a fire.

FIRE PREVENTION

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.

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 depending on logging conditions.

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

8. 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.

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.

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

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.

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

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.

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

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

13. 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.

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

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

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

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

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

WHAT ELSE TO DO BEFORE YOU EXPERIENCE A 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.

•

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

•

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

•

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

•

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.

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.

•

•

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. *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.

TYPICAL FIRE EXTINGUISHER ACCESS HOLE

•

If you are unable to open the access door(s), but can safely reach the fire extinguisher access hole, 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.

•

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.

1.11

•

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.

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.

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.

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 light will stay on and a HORN will sound when the oil level falls 12 gal. US (46L) below the FULL mark. When the light first comes on stop engine and look for signs of broken hoses or other leaks. Repair leaks and refill the tank to FULL mark on the sight gauge.

Restart engine and inspect for leaks. When the horn sounds stop the engine immediately.

Operating machine with horn sounding can cause hydraulic pumps to fail.

12. SAW ON - warning light This light is ON when the saw system is activated. It comes ON when the SAW SWITCH (Item 30) is switched to the ON position. It is possible that the light will NOT be ON even though the saw switch is ON due to the pilot system not being reset. In this case press the PILOT RESET button and turn the saw switch OFF and then ON. For more information on the pilot shut off system see PILOT SYSTEM SHUT-OFF SWITCH (Item 30) in this section.

9. FILTER BYPASS - warning light This light comes on when an oil flow restriction in excess of 15 psi is encountered at the return filters in the hydraulic oil reservoir. When this occurs the filters require immediate service. Excessive pressure drop through the return filters can cause the filter bypass valve to open.

19. HYDRAULIC OIL TEMPERATURE - gauge

16. VOLTMETER

Displays the current hydraulic oil temperature registered in the hydraulic reservoir.

Normal operating range is between 12 - 13.5 volts. A reading in excess of 15 volts indicates a possible faulty voltage regulator.

If the temperature goes beyond 180°F check the following:

A reading less than 12 volts indicates a possible faulty battery or alternator.

• Plugged oil cooler • Malfunction in a hydraulic circuit • High loads on the hydraulic system • Low hydraulic oil level

Earlier style gauges include a built-in RED WARNING LIGHT that will come ON if the voltage falls below 10.5v or rises above 15.5v.

17. ENGINE OIL PRESSURE - gauge The 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. It should normally operate between 40 and 60 psi. when the engine is running at full load rated speed, with SAE 10W30 oil and normal operating engine oil temperature of 115°C (240°F). If the gauge registers less than the above with engine running at high idle, check the engine oil level. If pressure drops below 15 psi., shut the machine down immediately.

Operating above 180°F will shorten hydraulic component life.

Earlier style gauges include a built-in RED WARNING LIGHT that will come ON if the hydraulic oil temp. rises above 85°C (185°F).

If the temperature reaches 210°F do not continue to operate the machine.

20. FUEL LEVEL GAUGE Capacity when full; 115 gal (US) Earlier style gauges include a built-in RED WARNING LIGHT that will come ON when the fuel level falls to 12.5 gal.

21. SWING BRAKE - switch

Earlier style gauges include a built-in RED WARNING LIGHT that will come ON if the pressure drops below 18 psi.

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

18. ENGINE COOLANT TEMPERATURE - gauge Displays the current engine coolant temperature. It should normally indicate between 88°C - 102°C (190°F and 215°F). If temperature goes beyond 102°C (215°F) reduce load on engine and check for plugged radiator. Unless temperature drops quickly, stop engine and determine cause. Do not continue to operate machine.

Earlier style gauges include a built-in RED WARNING LIGHT that will come ON if the coolant temperature rises above 102°C (215°F) 2.5

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.

engine is restarted or the arm rest lowered. In this case press the PILOT RESET button and turn the saw switch OFF and then ON. 23. LOW/DRIVE - switch IMPORTANT: On the 845 this switch when in DRIVE provides infinitely variable travel speeds/torque ranges, unlike similar travel range controls on some types of construction equipment.

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

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.

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. (c) Malfunction of the anti-stall system.

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

25. ETHER STARTING AID SWITCH (OPTIONAL) 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 ETHER push button switch, using short "bursts" while cranking engine at same time. Stop injecting fluid after engine starts. If engine begins to die during first few minutes, inject another "shot" of fluid.

To install a can of starting fluid, remove the safety cap and plastic spray button from the can.

Remove the canister from the solenoid assembly and remove the empty can. Install the new can of starting fluid in the canister. Reinstall and tighten the canister to hold the can in position.

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.

IMPORTANT: To prevent dust from being drawn into the engine, leave a can in place in the canister, or invert the canister and reinstall onto the solenoid assembly.

*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.

CAUTION

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 on the 845. It is not necessary to place the range switch in the LOW position.

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 light is ON when the saw system is activated. It comes ON when the saw switch is turned to the ON position. It is possible that the light will NOT be ON even though the saw switch is ON due to the pilot shut off system not being reset. In this case press the PILOT RESET button and turn the saw switch OFF and then ON.

*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.

For more information on the pilot shut off system see PILOT SYSTEM SHUT OFF in THIS SECTION (Item 32) in this section.

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 on the 845. It is not necessary to place the range switch in the LOW position.

23. TRACK, LOW/DRIVE - switch with light IMPORTANT: This switch when in DRIVE 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.

24. ANTI-STALL - switch with light This switch turns on an 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.

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

FIRE SUPPRESSION SYSTEM ACTUATOR

DAILY: Control box; GREEN light should be ON indicating a normal system condition and the RED light should be OFF. If the GREEN light is OFF the system should be checked for possible malfunction. When the RED light is ON, the system has discharged and must be immediately recharged.

The Nitrogen discharge can also occur MANUALLY by striking the knob on the actuator with the palm of the hand.

The nitrogen when released, (manually or automatically) opens a valve on the dry chemical cylinder to release the powder.

WEEKLY: Inspect all parts for damage, rust, corrosion or dirt. ensure thermostats are clean. Inspect seal wires on pull ring, they should be intact. Inspect gauges on cylinder and portable extinguishers, the pointer on the gauge should point to the green area.

WARNING The Squib is an explosive device NOTE: The fire suppression system will not fire even with the GREEN light ON or the RED light ON if the Nitrogen bottle has been removed or the line between the Actuator and the dry chemical cylinder is not intact.

Please read the OWNERS MANUAL APPLICABLE TO THE SYSTEM INSTALLED on this machine for additional information.

IN CASE OF FIRE: If a fire starts in any space protected by the system, DO NOT WAIT for the system to operate automatically. Instead, operate the system manually by removing the safety pin from the operating knob and striking the knob hard with the palm of the hand. There will be a hissing sound and a cloud of dry chemical in the discharge area.

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

2.25

Tigercat 845 Feller Buncher KIDDE FIRE SUPPRESSION SYSTEM ON Tigercat MACHINES

Controls and operation DURING SERVICE: Pay attention to the location on the 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.

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

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.

AFTER SERVICING:

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

Before operating the machine, it is important to thoroughly inspect all fire suppression system components to ensure that all hoses are still tight and that all wires are connected properly to the heat sensors and battery. To re-activate the system perform the above steps in reverse. When complete the green light on the control panel should be the only light ON. If the red light is ALSO ON call your local fire suppression dealer to have the system repaired.

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)

WARNING The Squib is an explosive device 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.

The system is now deactivated and cannot be (accidentally) actuated.

NOTE: See your local Kidde Fire Suppression dealer if you need a shunting spring and/or a nitrogen cartridge safety cap.

was plugged, then check the filter elements as they may need cleaning 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 every 2 hours to release dust buildup.

In addition to the LUBRICATION AND MAINTENANCE SCHEDULE in section 3 of this book, the following instructions should also be noted:

205-19AC

AIR CLEANER PRIMARY ELEMENT

The most common and damaging servicing problems are: OVER SERVICING Filter elements increase in dust cleaning efficiency as dust builds up on the media.

Looks can be deceiving. A filter that looks dirty 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.

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

205-22AC

NOTE: This does not apply to oil filters.

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

4. Always clean the inside of the outlet tube.

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

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

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.

IMPORTANT STEPS TO FOLLOW WHEN CHANGING FILTER ELEMENTS

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.

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.

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.

Tigercat 845 Feller Buncher STARTING IN COLD WEATHER

Controls and operation MACHINE PREPARATION

Cold temperatures require the use of the engine block heater and the hydraulic oil heater. The use of an ether starting aid may also be required.

SYSTEM TEST AND WARM-UP Before commencing harvesting operations, follow steps (a) thru' (o) to accomplish the following; • Warm up the hydraulic system.

IMPORTANT

• Test all systems for proper operation.

• Inspect for hydraulic oil leaks.

Cold startups can result in pump failure, refer to"HYDRAULIC OIL CHART" for recommended oil viscosities and temperature ranges.

CAUTION

Preheating of hydraulic oil is recommended as standard procedure in cold weather.

If any system fails to respond to the controls, stop the warm-up procedure and call a mechanic, otherwise serious damage to pumps and other components could result.

If a (ether) starting aid is being used; (a) Move throttle control to the HALF IDLE position.

Assuming machine was parked on level ground at last shutdown:

(b) Crank engine with starter one or two revolutions before injecting starter fluid.

(a) Start engine. (b) Ensure gauges and warning lights are indicating normal operating conditions.

(c) Momentarily depress ETHER push button 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.

(c) Check that all personnel are clear of the machine. (d) Press Pilot reset button (e) Raise throttle control to the MID position.

IMPORTANT

(f) Slowly raise and lower the stick boom and the main boom, check for proper operation.

To prevent damage to starter, do not engage starter motor for more than 15 to 20 seconds.

Wait 2 minutes between each attempt to start the engine. If engine fails to start, refer to engine manufacturers operator's manual.

With the felling head raised slightly off the ground: (g) Operate the accumulator and clamp arms and check for proper operation. (h) Tilt the felling head forward and back and check that it is operating correctly.

(d) Once the engine is running evenly and the engine oil pressure is at NORMAL, move the throttle control to the LOW IDLE position and allow to run for approx. 5 minutes or until the engine coolant temperature gauge begins to register. If the engine oil pressure does not register on the gauge within 15 - 20 seconds stop the engine.

(i) Swing the upper to the left and right. (j) When cold weather conditions exist, continue the process of warming up the hydraulic system by repeating steps (f) thru'’ (i) several times. As the hydraulic system warms up, engine speed can be increased gradually to the HIGH IDLE position. If the PUMP INLET or FILTER BYPASS warning lights come on decrease engine speed immediately and continue warming the system.

(e) Before applying any load to the engine proceed with MACHINE PREPARATION.

(k) Turn saw on. (l) Observe all boom operations. If any operations are not operating as they should, take the necessary steps to correct the problem.

2.43

Tigercat 845 Feller Buncher

Controls and operation TRAVELLING (BOOM RAISED)

After completion of the warm-up and system testing, rest the felling head on the ground and turn the saw OFF.

1. Select appropriate drive range, Range switch in LOW or DRIVE position.

(m) Put the swing brake ON.

When in LOW machine moves slower but with increased drive force.

(n) Move the throttle control to the LOW IDLE position.

When in DRIVE machine moves faster but with less drive force.

WARNING

All harvesting should be done with LOW.

Ensure that the saw blade has stopped rotating before leaving the cab.

2. Place swing brake switch in OFF position.

(o) Leave the cab and visually check hose connections and cylinders for leaks. Check under the machine for oil leaks.

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

3. Move throttle control to the HIGH idle position.

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. Open centre systems responded to larger lever angles with increased boom speeds, but this system will not. Relax and try to use the least amount of lever action you can.

WARNING Never use your bare hand to check for fluid leaks.

Fluid leaks under pressure may not be visible.

When searching for leaks, wear work gloves and use a wrench or piece of wood to move

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.

Refer to SET MARGIN PRESSURE in SECTION 4 of the SERVICE MANUAL Another feature of this system is that the maximum flow of each function, in each direction, can be tuned to your requirements.

This is easily done by changing the flow adjusting screws on each control valve. Take the time to set up your machine, as this greatly reduces fatigue.

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

2.44

Tigercat 845 Feller Buncher STOPPING ENGINE

Controls and operation

CARE OF THE MACHINE 1. Ensure that all fluid levels are always at the proper level. Use the lubrication and maintenance schedule in SECTION 3 of this book.

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

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

3. Apply grease to all lubrication points at required intervals.

1. Park machine on level ground and rest felling head on the ground.

4. Do not apply load to a cold engine.

2. Reduce engine speed to LOW IDLE and let run for approx. three 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.

5. Close and secure all doors and access covers.

4. Do not race engine before shut-off.

7. Always harvest trees in LOW driving range.

5. Set swing brake switch to ON.

8. 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.

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

Clean frequently but at least once daily.

6. Stop engine by turning ignition switch to the OFF position.

FELLING HEAD OPERATING INSTRUCTIONS AND SAFETY PRECAUTIONS 1. All tree harvesting should be carried out in LOW driving range.

2. See felling head manufacturers manual for proper operation of the felling head.

CLEANING INSTRUCTIONS FOR LEXAN WINDOWS

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: On the Tigercat 845 the windshield, side windows and door are LEXAN, the rear window is glass.

(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.

1. Rinse with lukewarm water.

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.
