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.

FIRE PREVENTION

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.

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.

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.

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.

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.

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.

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.

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.

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.

1.12

Tigercat 1055 Forwarder

Safety

FIRE PREVENTION continued

•

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.

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.

*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 •

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*

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

•

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 do so, turn OFF battery disconnect switch.

•

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.

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

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

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.

•

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

1.13

Tigercat 1055 Forwarder

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.

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.

1.14

•

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.

TOP OF HYDRAULIC TANK

The hydraulic oil fill pump, located on the top of the hydraulic tank is used to add oil to the hydraulic oil reservoir.

To add oil to the reservoir: Park the machine on level ground, with the crane in the “parked” position. Remove suction hose from storage compartment. Clean the suction hose, and remove cap. Open the right hand side access door on the hydraulic tank. Install hose into quick coupler on fill pump. Insert the end of suction tube into the supply drum and operate the pump by turning the switch on the fill pump to ON. The oil is pumped into the reservoir through the return filters. When the oil level in the tank is satisfactory, switch the fill pump OFF.

CAUTION When turning the vacuum pump switch to OFF always allow the tank to vent to the atmosphere for at least one minute before restarting the engine.

IMPORTANT Turning the vacuum switch OFF will stop the vacuum pump and open the tank to the atmosphere via a vent fitting. Always allow the tank to vent to the atmosphere for at least one minute before restarting the engine. Restarting the engine while the tank still has a vacuum may cause air to enter the hydraulic system and result in cavitation damage to hydraulic pumps and motors.

Replace the cap on the suction tube, disconnect from the fill pump, wipe dry and store in rear chassis compartment. Close the hydraulic tank doors.

CAUTION The vacuum pump function cannot be used with the engine running. This is a safety feature and must not be defeated in any way or extreme damage to hydraulic components may result.

STOPPING ENGINE:

RESTARTING AN ENGINE THAT HAS RUN OUT OF FUEL

CAUTION

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

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

1. Refill fuel tank completely.

2. Open vent plugs on the fuel filter head and the fuel/water separator filter head. Crack open the fuel supply line on the fuel injection pump. Prime the fuel system using the primer pump on the fuel filter/water separator.

When fuel free of air flows from the vent plugs and the fuel supply line, close the plugs and tighten the fuel supply line at the fuel injection pump.

1. Park machine on level ground with crane in the park position. Lower the blade or ladder (if equipped) to the ground.

WARNING

3. Bleed the system according to the engine manual procedures.

If ladder is not lowered it will lower automatically when the engine is stopped.

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

2. Reduce engine speed to LOW IDLE and let engine run for approximately three minutes to allow gradual dissipation of heat and reduce turbo speed. This also prevents loss of coolant by after boil and possible hot spot damage to the engine.

CAUTION To prevent damage to starter, do not engage starter motor for more than 15 to 20 seconds. Wait 2 minutes between each attempt to start the engine.

If engine fails to start, refer to engine manufacturers operator's manual.

3. Do not race engine before shut-off.

4. Set TRAVEL DIRECTION switch to OFF position.

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

Controls and operation

TRAVELLING WITHOUT A LOAD:

1. Once the machine has been positioned near the loading/unloading site, set the TRAVEL DIRECTION switch to OFF.

Place the crane in the park position and raise the snow blade (if equipped).

2. Rotate the seat (if needed) to get full view of the loading/unloading operation.

1. Set the CRANE/BLADE switch to OFF. 2. Set the TRAVEL DIRECTION switch to FORWARD or REVERSE. Set the TRAVEL SPEED switch to TRAVEL or CRAWL speed setting as required.

3. Set the CRANE/BLADE switch to WORKING RPM position. Engine speed will increase to WORKING SPEED 1450 RPM. The working speed range is adjustable (1250 RPM to 1800 RPM).

3. Set TRANSMISSION GEAR SELECTION switch to First Gear.

4. Operate crane, rotator, and grapple functions to pick up the load, and place it where desired. Refer to LEFT and RIGHT JOYSTICK instructions in THIS SECTION for specific information on crane, rotator, and grapple operating controls. Note that it is most suitable, for balance purposes to grip logs near the middle.

4. Operate the drive foot pedal to move the machine.

5. This machine is equipped with a single-axis proportional steering control lever. The speed that the vehicle responds to the steering control lever input will vary, depending on the distance that the steering control lever is moved. When operating on the road, a short movement of the steering control lever will not overcorrect and will steer a reasonably straight course. Operating in the woods requires quick steering changes and this is produced by a larger movement of the steering control lever, which will quickly change the vehicle's direction.

A) If the logs loaded in the bunk are accumulating to the top of the load gate extend the load gate by pressing the GATE switch to the UP position. Refer to GATE DOWN/UP in THIS SECTION. B) If the logs are dispersing to the lower portion of the bunks, be sure to retract the load gate by pressing the GATE switch to the DOWN position. This reduces the risk of damage caused by contact between the crane and the load gate. Refer to GATE DOWN/UP in THIS SECTION.

6. Use differential locks sparingly and ONLY when additional traction is required. Never continuously drive the machine with the differential locks on. Serious damage to the axles can result from using the differential locks when they are not needed for additional traction.

WARNING Do not load logs above the top of the load gate!

IMPORTANT

5. A) When loading is complete, park the crane on top of the load in such a way that the load restricts the crane from moving side to side.

Use differential locks sparingly. Never drive the machine with the differential locks on continuously. Serious damage to the axles can result from using the differential locks when they are not needed for additional traction.

B) When unloading is complete, return the crane in the park position.

6. Set the CRANE/BLADE switch to OFF position.

LOADING / UNLOADING OPERATIONS: Crane and grapple operations should always be performed while seated in the operator’s seat.

All crane and grapple controls will return to neutral automatically when released.

GENERAL Clean away all branches, bark and chips.

Clean up all traces of oil to avoid fires

CAUTION All handles, steps and platforms must be kept free of grease, oil, fuel, mud, snow and ice

Always have a fire extinguisher at hand and know how to use it For safety; when leaving the cab or leaving machine unattended or during service, always place the crane in the park position or other SECURE position, and lower the blade (if equipped). Turn the ignition switch off. Turn the battery disconnect switch off.

Clean around filler caps before checking or adding fluids.

Release hydraulic pressure and clean around hydraulic fittings before breaking connection.

Plug or cap immediately.

For safety, always block or support the crane and blade (if equipped) when working under them.

Clean up ALL spills immediately.

Always use clean oil and containers.

Drain dirty oil while still warm.

_______________________________________________________________________________________

Do not exceed recommended fluid levels.

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

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

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

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.

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

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.

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.

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.

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.

Also refer to FIRE PREVENTION in SECTION 1 of THIS MANUAL for additional information.

Before welding on machine be sure master switch is disconnected and disconnect multi pin connectors on engine CPU and engine wiring harness.

When welding, secure ground connection as close to working position as possible to prevent arcing across machined surfaces or through bearings 3.4

FILL CAP & TUBE

Filters that are an integral part of the engine (fuel and lubricating oil) should be serviced and replaced according to the engine manufacturer’s operation and maintenance manual.

Tier II engine fuel injection systems require cleaner fuel than Tier I engines. To accomplish this, Tier II engines typically use filters with a finer micron rating. If the fuel supply is dirty, the fuel filter must be replaced more frequently than recommended in the owner’s manual.

Operating the machine with a clogged fuel filter will result in low engine power. It is also recommended that the fuel/water separator bowl be drained daily.

IMPORTANT

•

NEVER PRE-FILL ANY HYDRAULIC FILTERS ON FORWARDERS

• HYDRAULIC RESERVOIR

HYDRAULIC RESERVOIR AND FILTER LOCATION The drive pump charge circuit contains a single element, full flow Tigercat hydraulic filter with a restriction indicator sending unit and a 3.4 bar (50 psi) third port bypass valve. The restriction indicator sending unit turns on the filter bypass warning light in the cab when an oil flow restriction in excess of 3.4 bar (50 psi) is encountered at the filter head. When a restriction is encountered, the bypass valve diverts oil back to tank via the third port to prevent unfiltered oil from entering the drive circuit.

1014-D015

Changing a pressure filter: 1. Park machine on level ground, install articulation lock bar, lower the snow blade (if equipped) and place the crane in the park position, stop engine, remove key, then switch battery disconnect off, and block wheels.

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

3. Place rags below to catch the spillage of oil.

4. Wearing face protection (in case of an oil spray), unscrew the old filter. Dispose of old filter and any oil properly.

5. Check the seating area for the gasket on the filter head and wipe it clean.

6. The new filter has an attached gasket. Apply hydraulic oil to the gasket surface.

7. Screw on the new filter until the gasket makes contact with the seat in the filter head.

8. Hand tighten filter an additional 1/2 turn only.

9. Start the engine and check for leaks.

3.13

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.

IMPORTANT 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.

AIR CLEANER UNLOADER VALVE

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 valve should suck closed at 1/3 throttle.

This 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, be sure to check the filter elements as they may need replacing as well. Reattach the valve to the tube.

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

AIR FILTER ELEMENTS

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

Warning lights in the cab will come ON when the elements in the engine air cleaner become excessively clogged with dust causing air intake restriction.

In addition, a filter restriction indicator is mounted on the engine intake tube side of the filter, this should show green when the engine is running at high RPM. Service is required if the indicator shows red.

3.16

Tigercat 1055 Forwarder

Lubrication and Maintenance

In addition to the SCHEDULED MAINTENANCE, the following instructions should also be noted.

IMPORTANT STEPS TO FOLLOW WHEN CHANGING FILTER ELEMENTS

The most common and damaging servicing problems are:

1. Thoroughly clean the air cleaner housing and surrounding area before opening air cleaner.

OVER SERVICING

2. Release the cover latch gently to reduce the amount of dust dislodged.

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

NOTE: This does not apply to oil filters.

IMPROPER SERVICING

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

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

5. Always clean the inside of the outlet tube and filter housing.

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

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.

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

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

7. Inspect the new filter for damage.

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

9. 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 here send dust directly to the engine.
