Tigercat 244 Loader

Safety 5.

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.

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 may have repositioned itself onto the engine and exhaust parts due to wind turbulence caused by the journey.

9.

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

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.

1.10

10. Steam clean the engine, 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.

Tigercat 244 Loader

Safety

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

•

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.

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.

*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.

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

WHAT TO DO IN CASE OF A MACHINE FIRE

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

•

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.

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

•

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.

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

•

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.

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

•

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.

•

If you can safely do so, turn OFF battery disconnect switch.

•

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

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

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.

Tigercat 244 Loader

Safety

FIRE PREVENTION continued

•

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.

Continued from page 11

•

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.

20229A

WHAT TO DO AFTER A FIRE

TYPICAL FIRE EXTINGUISHER ACCESS HOLE

•

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

•

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

•

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

1.12

•

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.

With the key switch in the OFF position and the key removed, turn the vacuum switch to the ON position to run the compressor/vacuum pump This will create a vacuum condition (9 in.Hg) in the hydraulic tank. The vacuum pump will automatically start and stop as necessary to maintain the tank vacuum. The vacuum switch will also lock out the start solenoid to prevent the engine from being started.

FOOT PEDAL

By creating a vacuum in the hydraulic tank, it becomes possible to perform service work on the hydraulic system without the need to drain the hydraulic tank. The vacuum inside the tank will "hold" the oil in the tank. The air compressor used for the hydraulic reservoir pressurization acts as a vacuum pump for this purpose with the use of a small solenoid operated diverter valve.

3. FOOT PEDAL - SWING Depress the Left side of the foot pedal to swing left.

Depress the Right side of the foot pedal to swing right.

The foot pedal will automatically return to the center position once released. The swing will cease when the foot pedal returns to center.

Relieve the vacuum in the tank by placing the vacuum switch in the OFF position and OPENING and CLOSING the air vent ball valve on the hydraulic tank. NOTE: Do not attempt to start the engine until the tank has been pressurized. See CHARGE TANK SWITCH in THIS SECTION.

4. MAX RPM - SWITCH Depressing the Max RPM rocker switch (4) will incrase the engine speed to 2270 RPM. DO NOT OPERATE at MAX RPM unless hydraulic oil temperature is above 38°C 100°F.

IMPORTANT It is recommended that the vacuum pump be operated once per week for about 30 minutes when the hydraulic system is at operating temperature. This will remove water that may have accumulated in the hydraulic tank as a result of condensation.

NOTE: To maximize fuel efficiency this switch should only be used on ocassion when extra power is required. See ENGINE SPEED SWITCH in this section for more details.

WARNING At no time should the high idle speed exceed the recommended value as serious damage to the pumps will result.

IMPORTANT It is recommended that the start key be removed while servicing the hydraulic system.

Do not attempt to START the machine or turn key to the RUN position. The vacuum pump only operates when the key switch is in the OFF position.

Do not leave machine unattended or overnight with vacuum pump on.

5. VACUUM TANK - SWITCH WITH LIGHT This is a two position ON/OFF switch. The light in the switch will come ON to indicate that the vacuum switch is turned ON.

First select a direction (up or down) using the Stabilizer Direction selector switch (6).

The center position on the switch turns off all stabilizers. This switch should be left in the center position whenever stabilizers are not being moved. This will prevent accidental operation of the stabilizers.

Next use buttons (7), (8), (9) or (10) to control each stabilizer separately or use the ALL button (11) to move all stabilizers at once. The All button should be used to ensure that each stabilizer is applying equal pressure to the ground prior to operating the loader or lifting any loads.

Also see SETTING THE MACHINE in THIS SECTION.

12. ANTISTALL - SWITCH WITH LIGHT This is a two position ON/OFF switch. The light in the switch will come ON to indicate that the antistall system is ON. Use this switch to turn ON the electronic load control system. This will automatically prevent overloading of the engine whenever several high load functions are in use at the same time. It should remain in the ON position during normal machine operation in engine RUN speed and in the OFF position when operating at less than engine RUN speed.

IMPORTANT: It should be noted that this anti-stall system will only allow full main pump flow with the engine running at speeds above 1900 RPM.

HYDRAULIC OIL RETURN MANIFOLD

OIL COOLER BY-PASS When starting operation during cold weather, the oil cooler by-pass is used to avoid passing oil through the cooler so that the hydraulic system may warm up faster. The by-pass valve should be opened up fully before starting the engine and left in this position until the hydraulic oil warms up to about 49 °C - 120 °F.

During this warm up period the engine should be kept at warm-up speed while the grapple functions are operated to generate heat. The hoist down function may also be used over relief for heating purposes.

This warm up procedure should be continued until the oil is warm enough that the pump suction light does not come on when the engine speed is increased to run speed. The engine should not be operated at MAX RPM until the oil temperature exceeds 38 °C - 100 °F.

The hydraulic oil temperature gauge should be carefully monitored to ensure that oil temperature does not exceed 71 °C - 160 °F. When the oil reaches this temperature the by-pass valve should be partially closed to permit some oil to pass through the cooler. The amount the valve needs to be closed will depend on the ambient temperature and on the work being done.

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.

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

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.

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.

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.

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. If equipped, read the fire suppression system manual and have the system serviced regularly by qualified personnel.

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

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.

The majority of return oil entering the hydraulic tank passes through 4 spin-on hydraulic oil filters. One of the filters is a water absorbing filter (color blue) which is in place to assist with the removal of unwanted moisture from the hydraulic oil (the filters are rated 10 micron abs).

DO NOT use bottom nut for filter installation or damage/leakage may result. Bottom nut is to assist in filter removal only.

FILTER HEAD

• • GASKET

Each filter head has a bypass valve with a 25 psi cracking pressure so that oil can bypass the filters if they become restricted. The "in" side of the filter heads are connected to a return manifold. A filter restriction indicator and an oil sampling connector are mounted onto the manifold. To check the condition of the filter elements; With the hydraulic oil at normal operating temperature, place engine throttle control to FULL and with no machine functions operating, the filter restriction indicator should be in the GREEN zone. If the pointer is in the RED zone replace all four filter elements.

Changing the filters: 1. Ensure Loader is on level ground with stabilizers down. Lower grapple to ground and stop engine.

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

Tigercat 244 Loader

Lubrication and Maintenance

In addition to the LUBRICATION AND MAINTENANCE SCHEDULE, the following instructions should also be noted.

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

AIR CLEANER MAINTENANCE

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

The most common and most damaging air intake servicing problems are: OVER SERVICING Filter elements increase in dust cleaning efficiency as dust builds up on the media. Looks can be deceiving. A filter that is 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 the engine manufacturer’s guidelines, should be replaced.

IMPROPER SERVICING

205-19A

Engine exposure to dust during servicing is the largest single factor contributing to engine damage due to dust. Abrasive dust can easily enter the intake system once the air cleaner element has been removed for replacement. The safety element reduces the risk, however it must also be replaced at every third primary element change.

AIR CLEANER PRIMARY ELEMENT

IMPORTANT STEPS TO FOLLOW 1. Release the seal gently to reduce the amount of dust dislodged.

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

205-22A

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 the old filter, it can help you detect foreign material on the sealing surface that may be causing leakage.

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 connection and ducts for air tight fit.

Ensure that all clamps, bolts and connections are tight. Leaks here send dust directly to the engine.

FILTER RESTRICTION INDICATOR A filter restriction indicator is located in the engine enclosure to the left of the frame access panel.

The indicator is remote mounted and is connected to the outlet side of the air filter with a 1/4" diameter hose. Service to the 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.

•• AIR CLEANER

AIR CLEANER UNLOADER VALVE This rubber valve on the tube of the air cleaner housing should be checked at the beginning of every shift. (8 hours) If this valve is missing, damaged or has become hard, it will cause the air cleaner to become ineffective. The unloader valve should be replaced every 1000 hours.

Remove the unloader valve from the tube of the air cleaner housing.

Check and clean the valve. A good valve should be soft and flexible. If it is plugged, then check the filter elements, they may need replacing. Re-attach the valve to the tube.

The valve should suck closed at engine warm-up speed.

When operating in high dust conditions this valve should be checked and squeezed every 2 hours to release dust buildup.
