When moving the machine, watch that enough clearance is available on both sides and above the machine or any of its attachments. Extra clearance may be required particularly where the ground is uneven.

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

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

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

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

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

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

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

•

If these are found, Do Not Touch!!!

•

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

•

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

•

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

MACHINE STABILITY AND TRACTION 26°

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

Whenever possible work within the normal working range of the boom system as shown in FIG. 1. Note that in any boom position, both inside and outside of the normal operating range, there is a risk of instability and tipping. When it is necessary to work outside of the normal working range, be aware that the stability of the machine is reduced. The risk of tipping is increased while operating in the reduced stability working range.

UPHILL

22° LH830-08 LH830-09

FIG. 2 UNDERCARRIAGE LEVELING ANGLES All efforts have been made in the design of the machine to reduce the risk of tipping, however it is not possible to eliminate the risk of tipping. To minimize the risk of tipping observe the following: • Do not attempt to operate this machine on slopes without first receiving proper training.

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

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

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

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

BOOM TO FRONT

•

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

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

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

CLIMBING SLOPE (FIG. 3)

BOOM TO REAR

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

Tigercat L830/LX830/X830 Feller Buncher OPERATING SAFETY PRECAUTIONS continued FELLING TREES Pieces of wood, debris from the ground and even teeth separating from the saw blade become potentially dangerous missiles when thrown from these machines.

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

Ensure that all saw tooth retaining bolts are at correct torque value.

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.

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.

Safety equipment and operator's are also moving in. Preplan to clear decks in advance before other equipment arrives.

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

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. 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.

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.

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: •

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

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

Never use this machine to clear a logging deck on a new tract of timber when the rest of the

Wear safety goggles for eye protection.

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

Pressure can be maintained in a hydraulic system long after the power source and pump have been shut down. Lower the attachment to the ground, stop engine and relieve trapped pressure before performing work on components, or disconnecting any hoses. Refer to PARKING BOOM diagrams (FIG.5 & FIG.6). Accumulators will self drain within 2 minutes of stopping the engine on this MODEL. Also, for machines equipped with pressurized hydraulic tanks (830*0191 to 830*0343, 830*0611 to 830*0999) , relieve pressure in the hydraulic reservoir by opening hydraulic tank vent valve and waiting until the sound of escaping air stops.

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

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.

FIRE PREVENTION

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

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

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

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

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

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

Safety 5. Remove debris and blow out dust regularly from the air intake doors, engine radiator, hydraulic oil cooler, A/C condenser core and charge air cooler to prevent overheating of the engine and hydraulics.

Refer to CLEANING A/C CONDENSER AND COOLING ASSEMBLY in SECTION 2 of the OPERATOR’S MANUAL. 6. 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 can fall into other areas of the machine and thereby spread a fire.

7. 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.

8. 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.

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

10. 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.

11. 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.

Safety 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.

•

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

Continued from page 17

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

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

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

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

16. 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.

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

*NOTE: Dry chemical fire suppression

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

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 3: TYPICAL COMMONLY USED SAW HOUSING, CONTINUOUS SKIRT WITH OPENING WHERE TREES ARE CUT. SNOUTS ON BOTH SIDES OF THE MOUTH.

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.

THROW ANGLE

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.

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.

7

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.

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.

6. ENGINE OIL PRESSURE - GAUGE This gauge displays information transmitted by the MDDM diagnostics module in the traditional analog format.

INSTRUMENT PANEL

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

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

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

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

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

In addition the amber LED will start to flash during active service code faults and the red LED will be ON during shut-down faults. These warnings will continue until the fault is corrected.

To view the active service codes, select the service code sub-menu by pressing the UP or 2.11

This is a two position switch labelled ON /OFF. The light in the switch will come ON when the switch is in the ON position.

This is a two position switch labelled ON /OFF. The light in the switch will come ON when the switch is in the ON position.

This switch turns on an electronic load control system 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.

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, 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.

IMPORTANT: It should be noted that this anti-stall system will only allow full main pump flow with the engine running at speeds above: Cummins QSL9 Engine 1700 RPM

CAUTION • Turning ON the swing brake while the boom is moving can damage the gearbox • NEVER operate the tracks with the swing brake ON as boom contact with the ground will damage the swing gearbox

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

If engine stalling occurs, check: (a) The ANTI-STALL switch is in the ON position. (b) The 2 amp fuse located in the large fuse (or circuit breaker) panel in the cab. (c) Malfunction of the anti-stall system.

NOTE: Under heavy track load it may still be 2.16

Controls and operation 12. SAW - SWITCH

This is a two position switch labelled LOW and DRIVE.

This is a two position switch labelled ON/OFF. Use this switch to turn the saw ON. A lockout button is incorporated into the switch to prevent the switch from being turned ON accidentally. To turn the switch ON, push and hold the lockout button UP and place the switch in the ON position.

IMPORTANT: This switch when in DRIVE provides infinitely variable travel speeds/torque ranges, unlike similar travel range controls on some types of construction equipment.

Place throttle in FULL position before turning saw ON.

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

NOTE: If the engine has been turned off or the pilot shut off system tripped (Front Door opened) with the saw switch left in the ON position, the saw will not start up when the engine is restarted or the front door closed. In this case press the PILOT RESET button and turn the saw switch OFF and then ON.

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

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

NOTE ALSO: On Harvester Model Machines this saw switch supplies power to the attachment's control systems.

13. COOLING FAN - SWITCH This is a two position "momentary" switch.

L830 machines only Press and hold this switch in the CLEAN (PURGE) position to run the cooling fan in reverse.

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

LX830 & X830 machines only Press and release this switch in the CLEAN (PURGE) position the cooling fan will automatically cycle forward to reverse and back.

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.

With this switch in the "normal" position the hydraulically driven cooling fan will be turning and drawing cool air through the debris screen and cooling assembly. The air is expelled to atmosphere through the perforated panels that make up the engine enclosure.

*This amount of adjustment can be anywhere from a slight reduction in speed to all the way down to LOW, this will be dependant on the terrain conditions encountered.

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

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

NOTE: The air flow in the CLEAN (PURGE) mode is substantially less than in the NORMAL (FORWARD) mode. Reduce load on engine whenever placing fan in CLEAN mode.

Tigercat L830/LX830/X830 Feller Buncher 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.

Controls and operation will automatically shutdown either immediately or will be delayed for 10 to 15 seconds if the machine is a leveller.

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

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

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

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

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

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

AVOIDING DAMAGE AND FALSE DISCHARGES DURING MACHINE SERVICE: Pay attention to the location of the components of the fire suppression system. Take care not to damage heat sensors or wiring, this includes hitting, cutting, bending, denting, etc. Damage to heat sensors due to shock could cause an accidental discharge of the system. Cut, pinched, or kinked wiring could cause false signals and lead to burnt wiring or an accidental discharge of the system.

In addition thermostats are sensitive to heat from welding torches, steam cleaning or other outside sources which may create a false discharge of the system. Cutting the wiring anywhere along the electrical circuits especially the detection circuits, will cause a false discharge.

If any of the components are damaged replace them immediately.

822-03

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

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

PROBLEMS AND CORRECTIVE ACTION

To Raise Firmly lift up on the height adjustment lever.

When the lever releases, hold it up while partially lifting the operator’s body weight from the seat.

When the seat is at the desired height, FIRMLY PUSH DOWN on the lever until the seat locks (a click should be heard).

RIDES TOO STIFF/SEAT TENDS TO PUSH OR THROW OPERATOR FORWARD The air ride control valve has over pressurized the seat air suspension. This typically happens because the operator is trying to use the air suspension to adjust the ride height rather than using height adjustment lever to raise the seat.

Refer to height adjustment.

To Lower Firmly lift up on the height adjustment lever.

When the lever releases, partially apply operator body weight to the seat until the seat is at the desired height. FIRMLY PUSH DOWN on the lever. Hold lever down until the seat locks into position (a click should be heard).

8. RETURN FILTERS ~ HYDRAULIC OIL

HIGH PRESSURE PILOT FILTER 822-D47 9A. HIGH PRESSURE PILOT FILTER (L830 MACHINES ONLY)

The majority of return oil entering the tank passes through 6 spin on hydraulic oil filters, one of the filters is a water absorbing filter (colour blue) which is in place to assist with removing unwanted moisture from the hydraulic oil. The filters are connected in parallel to three separate return filter heads.

The oil from the 3 return lines passes through return strainers located inside the hydraulic tank.

There is a hydraulic high pressure pilot filter placed ahead of the pilot supply valve (pressure reducing/pressure relieving valve) to filter the oil before it enters the pilot system.

The pilot filter should be changed regularly as a part of scheduled maintenance. A clogged filter will result in low pilot pressure. When a clogged condition is indicated by a loss of controls or slow response or by the clog indicator (if equipped) the pilot filter element will need to be changed at an earlier interval.

There is a bypass valve built into each of the filter heads which is preset at 25 psi. this bypass valve will open in the event the elements become restricted. However a 15 psi. pressure switch installed in the return manifold will turn on the FILTER BYPASS warning light in the cab before this happens.

The pressures stated are for normal operating conditions and temperatures.

Refer to FILTER AND LUBRICATION SCHEDULE and FILTERS, PILOT in SECTION 3 of THIS MANUAL for recommended servicing intervals and filter servicing information.

NOTE: This warning light may come ON during cold weather start ups.

EARLIER MACHINES ONLY

FILTER SERVICE NOTE

On earlier machines this filter incorporates a clog indicator.

The filters should be checked/changed when the FILTER BYPASS warning light in the cab comes ON.

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

MEDIUM PRESSURE PILOT FILTER (LX830 & X830 MACHINES ONLY) There is a medium pressure pilot filter mounted to the base of the charge/pilot/filter manifold. The filter receives hydraulic oil from the charge pump. The charge pump is a gear pump driven from the power take-off of the clamp pump and supplies pilot oil via the filter and the charge/pilot/filter manifold to the pilot system.

HAND FILL PUMP 11. HYDRAULIC HAND FILL PUMP 822-D46

The hydraulic hand fill pump, on the rear left door, is used for adding oil to the hydraulic tank. A male quick disconnect port is provided on the return filter manifold and mates with a female quick disconnect attached to the outlet hose on the hand pump. This ensures that any hydraulic oil added is filtered prior to entering the hydraulic tank.

Mounted on top of the manifold is a clog indicator. Under normal operating conditions (or when the hydraulic system is shut down) the indicator will show GREEN. When a pressure differential of 50 psi builds up inside the filter, the indicator will show RED, indicating a clogged filter.

Tigercat L830/LX830/X830 Feller Buncher Controls and operation TRAVELLING (BOOM RAISED) OPERATING TIPS WITH LOAD SENSING 1. Select the appropriate drive range.

Place the track switch in the LOW or DRIVE position.

When in LOW the machine moves slower but with increased drive force. All harvesting should be done in LOW. When in DRIVE the machine moves faster but with less drive force. Travelling over longer distances (and not harvesting) should be done in DRIVE to allow for faster travel speeds when the terrain permits. DO NOT travel down steep slopes in DRIVE range. 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.

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.

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

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

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

HORIZONTAL REACH MOTION CHARACTERISTICS This 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.

CARE OF THE MACHINE

REMOVING HAIRLINE SCRATCHES

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

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 instructions provided by the polish manufacture be followed.

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

3. Always install door safety struts before working in the engine area.

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

5. Do not apply load to a cold engine.

6. Close and secure all doors and access covers.

7. Do not allow branches, twigs, leaves or pine needles to build up around radiator intake doors or anywhere else on the machine. Clean as operating conditions warrant but at least once day all debris must be remove from the machine interior.

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.

8. Always harvest trees in LOW driving range.

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

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

CLEANING INSTRUCTIONS FOR LEXAN WINDOWS NOTE: On the Tigercat 822 and 830 all of the windows are made of LEXAN MARGARD except the side door window.

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.

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.

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.

Lubrication and Maintenance

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

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

Always have a fire extinguisher at hand.

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

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

Clean up spills as soon as possible.

Always release pressure in hydraulic tank before breaking a connection. For machines with pressurized tanks only (830*0191 to 830*0343, 830*0611 to 830*0999).

Always use clean oil and containers.

Drain dirty oil while still warm.

Always install door safety struts when working on machine.

Clean fire suppression system sensors.

CHECK EMERGENCY EXITS MONTHLY~

Do not exceed recommended fluid levels.

Two alternate exit routes are provided on the LH. side and roof of the cab. These are only to be used if the front door cannot be opened.

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

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

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

Refer to the and SIDE DOOR AND ESCAPE HATCH EMERGENCY EXIT MAINTENANCE GUIDE in SECTION 2 of the OPERATOR'S MANUAL for checking procedure.

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

Before welding on machine, be sure to disconnect all electrical connections and follow all servicing safety precautions as outlined in the WELDING, PRIOR TO of SECTION 1 in THIS MANUAL. When welding, secure ground connection as close to working position as possible to prevent arcing across machined surfaces or through bearings.

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

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

CAUTION

Clean away all branches, bark and chips.

Clean up all traces of oil to avoid fires.

Inspect the EXHAUST SYSTEM DAILY for any signs of LEAKAGE. Check for worn, cracked, broken, or damaged pipes or muffler.

Also check for missing or damaged bolts or clamps. Should any exhaust leaks or defective parts be found, repairs must be made immediately. Engine exhaust leaks can cause fires, DO NOT OPERATE the machine until the exhaust leak is repaired.

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.

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 Continued on page 4

3.3

Tigercat L830/LX830/X830 Feller Buncher

GENERAL Continued from page 3

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.

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.

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

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

Also refer to the SAFETY section of this manual for additional information on how to prevent fires from starting on the machine.

When performing maintenance procedures or setting up a machine equipped with an ER boom system, the following points must be noted:

830-07

PARKING BOOM. FIG.5

HOIST CYLINDER FULLY RETRACTED

•

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 boom is properly parked for service (as described on this page, see also fig. 5 & fig. 6) and engine is shut off before disconnecting any hydraulic lines.

Also, for machines equipped with pressurized hydraulic tanks (830*0191 to 830*0343, 830*0611 to 830*0999) , relieve pressure in the hydraulic reservoir by opening hydraulic tank vent valve and waiting until the sound of escaping air stops.

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.

(a) The machine is parked on level ground with the head sitting flat on the ground. (b) The stick cylinders are fully extended (fig. 5) or the hoist cylinder fully collapsed (fig. 6). c) The tip of the stick boom supported . d) Do NOT rely on the attachment to support the boom system during servicing. Slow leakage in the hydraulic components can cause the attachment to move unexpectedly.

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

HYDRAULIC TANK PRESSURE GAUGE

•• • •

• 1 - WATER ABSORBING RETURN FILTER (COLOUR BLUE)

The majority of return oil entering the tank passes through 6 spin on hydraulic oil filters, one of the filters is water absorbing filter (colour blue) which is in place to assist with removing unwanted moisture from the hydraulic oil. The filters are connected in parallel to three separate return filter heads.

The oil from the 3 return lines passes through return strainers located inside the hydraulic tank.

There is a bypass valve built into each of the filter heads which is preset at 25 psi. this bypass valve will open in the event the elements become restricted. However a 15 psi. pressure switch installed in the return manifold will turn on the FILTER BYPASS warning light in the cab before this happens.

The pressures stated are for normal operating conditions and temperatures.

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

Direct contact with oil implies a risk of skin complaints. Oil on skin should be washed off immediately with soap and water. Refer also to WORKING WITH OIL in SECTION 1 of THIS MANUAL.

•

••

HYDRAULIC OIL FILTERS HYDRAULIC OIL RETURN FILTERS 422-07

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

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

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

HIGH PRESSURE PILOT FILTER 822-D47 HYDRAULIC HIGH PRESSURE PILOT FILTER (L830 MACHINES ONLY)

4.

There is a hydraulic high pressure pilot filter placed ahead of the pilot supply valve (pressure reducing/ pressure relieving valve) to filter the oil before it enters to pilot system.

The pilot filter should be changed regularly as a part of scheduled maintenance. A clogged filter will result in low pilot pressure. When a clogged condition is indicated by a loss of controls or slow response or by the clog indicator (if equipped) the pilot filter element will need to be changed at an earlier interval.

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.

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.

Refer to FILTER AND LUBRICATION SCHEDULE in THIS SECTION for recommended servicing intervals.

On earlier machines this filter incorporates a clog indicator.

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

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. A“Clogged” condition will result in low pilot pressure. If a loss of controls or slow response occurs, filter element may need to be changed.

PILOT FILTER AND FAN CHARGE PRESSURE FILTERS MEDIUM PRESSURE CHARGE PILOT FILTER (LX830 & X830 MACHINES ONLY) There is a medium pressure charge pilot filter mounted to the base of the charge/pilot/filter manifold. The filter receives hydraulic oil from the charge pump. The charge pump is a gear pump driven from the power take-off of the clamp pump and supplies pilot oil via the filter and the charge/ pilot/filter manifold to the pilot system.

Mounted on top of the manifold is a clog indicator.

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

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

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

A small pressure accumulator is used in the pilot supply circuit to ensure an adequate supply of pilot control oil under all operating conditions.

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

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.

NOTE: This does not apply to oil filters.

FILTER RESTRICTION INDICATOR

••

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.

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

822-D42 FILTER RESTRICTION INDICATOR FILTER RESTRICTION INDICATOR

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

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.

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.

CLEAN OUT COVER

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.

••

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 center.

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.

AIR CLEANER UNLOADER VALVE

AIR INTAKE CLEANOUT COVER

AIR INTAKE CLEANOUT COVER PLATE

This rubber valve on the tube of the air cleaner housing should be checked before every shift (8 hrs). If this valve is missing, damaged or has turned hard, it will cause the air cleaner to become ineffective. The valve should be replaced every 1000 Hours.

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

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

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

The precleaner receives air via an air intake grill on the left side of the power door cover and through a passage way fabricated into the power door. With the door opened, a cover plate can be removed to allow access behind the engine air intake grill to remove any accumulation of debris.

In extremely cold weather it is possible to run the engine with this cover removed to allow the engine to draw warmer air from inside the engine enclosure.

IMPORTANT: If the cover is removed, it MUST BE REINSTALLED when operating in warmer outside temperatures otherwise the engine will run at a higher temperature and less Horsepower.
