GENERAL SAFETY PRECAUTIONS

KEEP BACK 500 FEET

Remember that safety is a prime responsibility of all.

To minimize the risks and promote safety at all times, this section of the operator’s manual details a number of safety rules which should always be followed and obeyed.

Study all the safety messages in this manual and on the labels on the machine carefully.

When approaching an operating machine on foot, stay at least 500 feet (150M) away until the operator recognizes your presence. Make sure that all harvesting equipment is shut down before advancing to the machine.

DANGER ROTATING SAW The safety of persons outside the cab is the responsibility of the machine operator.

Follow all instructions from safety inspector and supervisors.

Always avoid the discharge side of a felling sawhead. A sawhead's high-velocity discharge of debris requires a safe separation distance.

WARNING The saw guard must be installed when working on the saw motor hydraulic circuit or when the saw head is not being used.

Before installing or removing the saw guard or locking bolt, saw blade must be at a complete stop and engine must be shut down.

You must be fully trained to operate this piece of equipment. Know the capabilities and the limitations of the equipment. Learn the most efficient operating techniques.

Do not let untrained persons operate the machine.

Wear a suitable hearing protective device such as earmuffs or earplugs to protect against noise.

Prolonged exposure to loud noise can cause impairment or loss of hearing.

Use recommended protective clothing and safety devices such as gloves, safety boots, safety hat, goggles, and ear protection when necessary.

These safety rules highlight both general and specific measures that the operator should be familiar with and adhere to. More specific measures are illustrated with pictograms which may also be attached to the machine in locations pertinent to their respective message. Keep safety labels in good condition. Repair or replace damaged labels.

1.3

Use the handrails and steps provided when mounting and dismounting from the machine.

Do not climb onto or jump off the machine at any time.

Do not use the machine foot controls as steps.

Tigercat 845B 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.

Check windows for scratching, crazing and cloudiness that could impair clear visibility all round the machine.

Maintain a charged fire extinguisher on the vehicle at all times and KNOW HOW TO USE IT. 1.4

Safety decks in advance before other equipment arrives.

OPERATING SAFETY PRECAUTIONS CONTINUED

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

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

Stop the saw blade before leaving the cutting area.

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

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

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

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

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

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

Always replace saw tooth retaining bolts when replacing saw teeth.

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

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

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

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

When parking the machine;

Shut down machine immediately if vibration occurs during cutting.

Check that the saw discharge area is clear and undamaged.

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

Do not over load felling head.

•

Park on level ground only and engage the swing brake.

•

Do not park on a hillside or incline.

•

Lower felling attachment onto level ground.

•

Stop the engine.

•

Turn the master disconnect switch off if the vehicle is to be parked for an extended period of time (Example - overnight).

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

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

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

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

When transporting the machine watch that enough clearance is available on both sides and above the machine or any of its attachments to avoid contact with power or telephone lines, bridge structures, etc.

When backing away from a cut, watch out for obstacles in your path.

Before transporting the machine check to ensure that all doors, panels and access covers are installed properly and secured. Improperly secured doors or panels pose a serious danger to pedestrians and other vehicles.

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

Safety 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. 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.

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.

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

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.

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

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.

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.

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

Safety 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.

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

•

Shut the engine off.

•

Activate the fire suppression system*

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

•

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.

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

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

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 •

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.

•

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.

Safety 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.

TYPICAL FIRE EXTINGUISHER ACCESS HOLE

Continued from page 15

•

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.

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.

The pressure in the hydraulic tank is maintained by a compressor located in the toolbox section of the upper frame. The compressor is turned ON and OFF by operating the hydraulic tank pressurization switch located on the control panel. After any major hydraulic maintenance has taken place, the initial pressure in the tank at startup should be raised to approximately 6 psi., this reading will fall after startup as the level of the oil inside the tank drops.

For more information on the pilot shut off system see PILOT SYSTEM SHUT OFF in THIS SECTION. 25. TRACK, LOW/DRIVE - switch with light 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.

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.

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.

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.

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

*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.

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.

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.

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.

Tigercat 845B Feller Buncher PROBLEMS AND CORRECTIVE ACTION

Controls and operation

RIDES TOO STIFF/SEAT TENDS TO PUSH OR THROW OPERATOR FORWARD The ride adjustment knob has been tightened (turned counter-clockwise) too much. This typically happens because the operator is trying to use additional ride adjustment knob rather than the height adjustment lever to raise the seat.

Operator is riding the seat in the low height position setting. Refer to HEIGHT ADJUSTMENT. RIDES TOO SOFT OR BOTTOMS OUT AND PINCHES OPERATOR The seat ride adjustment knob has not been tightened (turned counter-clockwise) enough.

Insufficient ride adjustment exaggerates the kneeaction movement of the seat. This usually happens because the operator is trying to lower the seat by decreasing the amount of ride adjustment instead of using the Height Adjustment lever. Refer to HEIGHT ADJUSTMENT. SEAT TOO HIGH/SEAT TOO LOW There are several things which can cause improper seat height. Refer to the HEIGHT ADJUSTMENT and adjust seat to the desired position. If the proper height cannot be reached using one of the four height adjustment settings, it may be necessary to install the seat on a higher base.

OPERATOR’S LEGS FALLING ASLEEP The seat is adjusted too high, and the ride adjustment knob has not been tightened (turned counter-clockwise) enough, resulting in the operator sitting in a “bucket”. Refer to HEIGHT ADJUSTMENT and RIDE ADJUSTMENT.

Tigercat 845B Feller Buncher KIDDE FIRE SUPPRESSION SYSTEM PDI AND SERVICING

Controls and operation DURING 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. 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.

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.

Tigercat 845B Feller Buncher STARTING ENGINE:

Controls and operation RESTARTING AN ENGINE THAT HAS RUN OUT OF FUEL

1. Ensure that Pre-Start checks have been performed and that the area is clear of personnel prior to starting the engine.

If the engine runs out of fuel, the fuel line must be primed:

2. Sound horn to warn personnel of machine start-up.

1. Refill fuel tank completely.

2. Remove engine fuel filter and fill with clean fuel.

3. Move throttle control to the LOW IDLE position.

3

4. Turn ignition switch to the START position to crank engine.

Bleed the system according to engine manual procedures.

4. Crank engine until it starts. If it fails to start after 20 seconds, stop and wait for 2 minutes before trying again.

5. When engine starts release ignition key to RUN position.

6. Keep throttle in IDLE position until engine oil pressure registers on gauge.

NOTE: The use of ether to aid in starting the engine is not recommended.

NOTE: If the engine does not start after three attempts, check the fuel supply system.

Absence of blue or white exhaust smoke during cranking indicates no fuel is being delivered.

IMPORTANT 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.

IMPORTANT After engine has started, keep engine speed low until engine oil pressure registers on gauge. If it does not register within 10 seconds, stop engine and investigate cause.

Allow a cold engine to warm up at LOW IDLE for at least five minutes before applying any load. Check all gauges often during the warm up period.

CAUTION Do not start engine by shorting across starter terminals. Start engine only from operator's seat.

If engine stalls while operating the machine, Turn the ignition key to the OFF position AND REPEAT STEPS (1) THROUGH (6).

2.45

Tigercat 845B Feller Buncher STARTING IN COLD WEATHER

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

Cold temperatures require the use of the engine block heater and the hydraulic oil heater, Refer to HYDRAULIC OIL HEATER in THIS SECTION. The use of an ether starting aid may also be required.

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

BY-PASS VALVE

BY-PASS VALVE ADJUSTING SCREW

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

••

•• MAINE LINDE VALVE

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

•

OIL COOLER BY-PASS VALVE 845B-D28 OIL COOLER BY-PASS VALVE

IMPORTANT

On later 845B models, an oil cooler by-pass valve has been installed on one of the two "tank" return ports on the main Linde valve. The by-pass valve incorporates a 100 psi check valve. If the oil cooler causes a resistance in excess of 100 psi. to the return oil entering the oil cooler, the check valve will open and direct a portion of the hydraulic oil to tank. In the winter months this resistance could be caused by cold, thick oil and will be noticeable by the hydraulic oil temperature gauge staying in the 'COLD' zone.

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. (d) If the engine oil pressure does not register on the gauge within 15 - 20 seconds stop the engine.

Allow engine to run for approx. 5 minutes or until the engine coolant temperature gauge begins to register.

To compensate for the cold temperatures an adjusting screw on the by-pass valve can be used to hold the by-pass check valve in the OPEN position, permanently allowing return oil from the maine Linde valve "tank" port to flow directly to the hydraulic tank and by-pass the oil cooler.

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

To make this adjustment loosen the locknut on the 100 mm long adjusting screw and screw the adjusting screw IN as far as it will go. Tighten the locknut on the adjusting screw. In the warmer months loosen the locknut and unscrew the adjusting screw until the end of the screw is no longer in contact with the end of the check valve poppet, this will be noticeable by the screw turning easier. Tighten locknut on adjusting screw.

2.46

Tigercat 845B Feller Buncher STOPPING ENGINE 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.

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

• Test all systems for proper operation.

• Inspect for hydraulic oil leaks.

1. Turn the saw switch to the OFF position and STOP the saw blade. This should be done before leaving the cutting area.

CAUTION

2. Find a clear and level area a least 50 feet from any other equipment to park the machine.

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.

3. Stop the machine and lower the saw head onto firm ground.

Assuming machine was parked on level ground at last shutdown:

2. Reduce engine speed to LOW IDLE and let run for approximately 3 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.

(a) Start engine.

4. Do not race engine before shut-off.

(d) Press Pilot reset button

5. De-activate the pilot system by lifting the left arm rest.

(e) Raise throttle control to the MID position.

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

7. Saw blade must be stopped before exiting cab.

8. Install saw blade guard.

9. Perform daily maintenance at the end of the shift (Greasing, cleaning engine compartment). This allows the machine time to cool down while under the watchful eye of the operator.

(b) Ensure gauges and warning lights are indicating normal operating conditions. (c) Check that all personnel are clear of the machine.

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

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. (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. (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.

2.47

Tigercat 845B Feller Buncher

Controls and operation

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

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

Place the track switch in the LOW or DRIVE position.

(m) Put the swing brake ON. (n) Move the throttle control to the LOW IDLE position.

When in LOW the machine moves slower but with increased drive force. All harvesting should be done in LOW.

WARNING

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 more than 10 minutes, take 5 minute breaks, this will help prevent the track drive gearboxes from over heating.

Ensure that the saw blade has stopped rotating before leaving the cab. (o) Leave the cab and visually check hose connections and cylinders for leaks. Check under the machine for oil leaks.

WARNING

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.

Never use your bare hand to check for fluid leaks.

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

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.

2.48

Tigercat 845B Feller Buncher 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.

Controls and operation SPECIAL OPERATING INSTRUCTIONS FOR ER BOOM SYSTEM NORMAL HORIZONTAL REACH MOTION PERFORMANCE CAN BE EXPECTED IN THIS AREA

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

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.

845C-008

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.

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

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

Tigercat 845B Feller Buncher CLEANING INSTRUCTIONS FOR LEXAN WINDOWS NOTE: On the Tigercat 860 all of the windows are made of LEXAN. 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.

Controls and operation 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.

Compatible Cleaning Agents Aqueous Solutions of Soaps and Detergents Formula 409 Top Job Freon T.F. VM&P grade Naphtha Joy Windex with Ammonia D Palmolive Liquid 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.

(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.

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. Clean around filler caps before checking or adding fluids.

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

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 and the speed control 25 pin connector in cab are disconnected.

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.

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.

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

Always install roof safety strut when working in engine compartment.

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

Tigercat 845B 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:

845B-42

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.

ER. BOOM SYSTEM. FIG.1 HOIST CYLINDER FULLY RETRACTED

•

TIP OF STICK BOOM FULLY SUPPORTED 845B-43

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 generally does not recommend the pre-filling of spin-on filters due to the risk of damage to the hydraulic system caused by unfiltered oil. Unfiltered oil used to pre-fill filters enters directly into the hydraulic circuit. Contaminants in unfiltered oil can cause significant and costly damage to hydraulic valves, pumps and motors. The cleanliness of hydraulic oil cannot be guaranteed unless it is always prefiltered before use.

13. Refuel and check for leaks.

A small pressure 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 no pressure is present before unscrewing the filter bowl.

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

6. Place rags below to catch any spilt oil.

HIGH PRESSURE PILOT FILTER

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

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.

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

AIR CLEANER UNLOADER VALVE 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.

218-21B

PRECLEANER

AIR CLEANER The air cleaner on this machine uses 2 filter elements, a primary element and a safety element accessible through the rear door.

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

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

The valve should suck closed at about 1/3 of full 3.20

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

INTAKE TUBING AND JOINTS 245-3 INTAKE TUBING AND JOINTS Replace turbocharger rubber inlet elbow and coupling - High temperatures in this area can cause the rubber to harden.

Check ALL air intake tubing, rubber couplings and band clamps for signs of wear and leakage.

FILTER RESTRICTION INDICATOR

FILTER RESTRICTION INDICATOR A filter restriction indicator is connected to the outlet side of the air filter. Service to the air filter is required when the indicator shows RED. This indicator provides a continuous reading whether the engine is running or is shut down. After servicing the filter, reset the indicator by pressing down on the reset button.

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.

In addition to the LUBRICATION AND MAINTENANCE SCHEDULE in section 3 of this manual, please note the following: The most common and damaging servicing problems are:

6. Inspect the new filter for damage.

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

NOTE: This does not apply to oil filters.

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

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

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

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

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

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.

3.22

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

8. Check connections and ducts for air tight fit. Ensure that all clamps, bolts and connections are in the correct location and tight. Check rubber elbows for damage.

Leaks in these locations send dust directly to the engine.
