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.

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.

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

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.

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 produce a highly corrosive acid 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: •

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.

•

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

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.

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.

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.

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

Machine should be washed completely at every major service.

Safety

FIRE PREVENTION

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

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

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

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

Dispose of fluids properly.

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

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

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

3. Remove debris and blow out dust regularly from the air intake doors, engine radiator, hydraulic oil cooler and A/C condenser core to prevent overheating of the engine and hydraulics. Refer to CLEANING A/C CONDENSER, OIL COOLER AND RADIATOR in SECTION 2 of the OPERATOR’S MANUAL. 4. Blow off all debris and dust accumulated near hot engine exhaust components (turbocharger and exhaust manifold as well as exhaust pipes and muffler) at the completion of each work shift or more frequently depending on logging conditions.

Visual inspection after blow off to ensure thorough cleanliness is vital. Engine exhaust systems provide numerous small pockets where saw dust, small wood chips and other flammable forest debris can gather. Even small accumulations close to hot exhaust components can ignite and smolder. If dislodged by vibration this smoldering debris 1.14

Tigercat LS870 Shovel Logger FIRE PREVENTION CONTINUED can fall into other areas of the machine and thereby spread a fire.

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

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

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

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

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

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

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

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

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

WHAT ELSE TO DO BEFORE YOU EXPERIENCE A FIRE

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

•

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

•

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

•

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

•

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

•

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

•

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

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

•

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

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

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

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

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

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

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

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

Safety

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

At all times ensure your own personal safety and the safety of anyone that may be in the area. Approach any fire with extreme caution.

•

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

•

Shut the engine off.

•

Activate the fire suppression system*

•

Radio or call for help (as appropriate).

•

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

•

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

•

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

•

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

•

Use the PASS method with most extinguishers.

•

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

•

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

•

•

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

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

•

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

•

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

20229A

TYPICAL FIRE EXTINGUISHER ACCESS HOLE

•

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

•

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

•

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

WHAT TO DO AFTER A FIRE •

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

•

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

•

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

•

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

14. ENGINE DISPLAY AND DIAGNOSTICS MODULE (MDDM) This is a multifunction display and fault warning module that enables the operator to view many different engine parameters and engine codes. The module includes a two line eight character backlit LCD, displaying data in either imperial or metric units.

20. TACHOMETER This meter indicates the engine speed.

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.

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

21. ENGINE OIL PRESSURE - gauge

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

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

ACTIVE ENGINE SERVICE CODES

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

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

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

These warnings will continue until the fault is corrected.

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

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

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

33. TRACK,LOW/DRIVE - switch with light

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

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.

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

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

If engine stalling occurs, check:

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.

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

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.

50 LBS PRESSURIZED CYLINDER

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

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

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

To manually operate the system: 1. Pull locking pin.

2. Press red FIRE manual actuation switch.

"SYSTEM OK" LIGHT

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

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

FIRE SUP. SYSTEM, AMEREX continued:

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.

For none levelling machines the automatic engine shutdown feature will shutdown the engine immediately the fire suppression system is discharged. For levelling machines there will be a delay of between 10 to 15 seconds before the engine shuts down. The time delay period is a factory setting. This delay feature allows the operator to lower the load or move the machine to a safer location before the engine shuts down. The operator can extend the delay by pressing the SHUTDOWN RESET button on the control panel to repeat the preset delay period. This button can be pressed repeatedly until the operator has brought the machine to a safe stop. The SHUTDOWN RESET button does not delay the discharge of the fire suppression system.

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

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

INSPECTION OF THE AMEREX FIRE SUPPRESSION SYSTEM AND PORTABLE EXTINGUISHERS: DAILY:

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

•

Check the pressure gauge on the agent cylinder and all portable extinguishers. Proper pressurization is indicated when the pointer is in the green zone.

TRAVELLING (BOOM RAISED)

CARE OF THE MACHINE

1. Select the appropriate drive range.

1. Ensure that all fluid levels are always at the proper level. Refer to the LUBRICATION AND MAINTENANCE SCHEDULE in SECTION 3 of THIS MANUAL.

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.

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

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

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

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

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

For a more detailed description of drive range refer to TRACK, LOW/DRIVE SWITCH in THIS SECTION.

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

2. Place swing brake switch in OFF position.

3. Move throttle control to the HIGH idle position.

7. Do not allow branches, twigs, leaves or pine needles to build up around radiator intake doors or anywhere else on the machine. Clean frequently but at least once daily.

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

8. Do not apply load to a cold engine.

9. Always harvest trees in LOW driving range.

OPERATING TIPS WITH LOAD SENSING

10. Never park machine with felling head raised off the ground. Be sure that the felling head is resting on the ground before servicing or parking the machine.

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.

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

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

Controls and operation GRAFFITI REMOVAL

CLEANING INSTRUCTIONS FOR LEXAN WINDOWS

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

NOTE: On the Tigercat 860 all of the windows are made of LEXAN. 1. Rinse with lukewarm water.

(B) To remove labels, stickers, etc., the use of kerosene, VM&P Naphtha, or petroleum spirits is generally effective. When the solvent will not penetrate sticker material, apply heat (hair dryer) to soften the adhesive and promote removal. GASOLINE SHOULD NOT BE USED.

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

3. Rinse with clean lukewarm water.

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

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

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

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

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

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

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

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

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

Clean around filler caps before checking or adding fluids.

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

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

Clean up spills as soon as possible.

Always release pressure in hydraulic tank Before breaking a connection.

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

Always use clean oil and containers.

Drain dirty oil while still warm.

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

Do not exceed recommended fluid levels.

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

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

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

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

1. Pine needles and bark when allowed to accumulate, form a fuel source that when ignited is extremely difficult to extinguish. A thorough program of regular cleaning and washing will reduce the possibility of a fire starting. In the event a fire does start, the regular cleaning program will improve the chances of successfully extinguishing a fire.

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

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

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

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

Clean away all branches, bark and chips.

Clean up all traces of oil to avoid fires.

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

Always have a fire extinguisher at hand.

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

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

HYDRAULIC FILTER SERVICING GUIDELINES

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

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

IMPORTANT

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

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

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

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

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

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

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

6. Place rags below to catch any spilt oil.

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

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

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

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

Wipe clean.

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

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

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

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

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

21. Using hand fill pump: Loosen one of the air bleed hoses on top of one of the filter covers to allow air to escape from the filter box. Tighten air bleed hose and continue pumping with the hand fill pump. Repeat until clean, air-free oil emerges from air bleed hose, tighten air bleed hose. Replace plug on fill hose.

22. Recheck oil level and add hydraulic oil up to FULL mark using hand fill pump.

NOTE: Changing strainers and filters and replacing the hydraulic oil tends to aerate the oil.

For maximum pump life, the machine should sit for 1 hour after servicing to allow entrained air to escape from the oil prior to applying working pressures to the pumps.

Lubrication and Maintenance AIR CLEANER

ENGINE AIR PRECLEANER The engine air precleaner cleans engine air before it reaches the air cleaner filter elements. It removes contaminants such as dust, powder, insects, rain and snow. This precleaner is self powered and self cleaning requiring virtually no maintenance.

However, it should be checked periodically to make sure that foreign materials have not plugged the intake area or the discharge port area and that the rotor spins freely.

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

manufacturer's guidelines, should a filter be replaced.

AIR CLEANER UNLOADER VALVE

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

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

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

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

Abrasive dust can easily enter the intake system Check and clean the valve. If it was plugged, then once the air cleaner cover and protective filter check the filter elements as they may need to be element is removed for replacement. The safety replaced as well. Reattach the valve to the tube. The element does reduce this risk but it should also be valve should suck closed at about 1/3 of full throttle. replaced at every third primary element change.

When operating in high dust conditions this valve should be checked and squeezed frequently to IMPORTANT STEPS TO FOLLOW WHEN release dust buildup.

CHANGING FILTER ELEMENTS 1. Release the cover latch gently to reduce the amount of dust dislodged.

•• RESET BUTTON

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.

FILTER RESTRICTION INDICATOR

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

FILTER RESTRICTION INDICATOR

376-11A

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 centre.

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 the reset button.

RUBBER ELBOWS AND TUBING

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.
