Safety 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).

GENERAL SAFETY PRECAUTIONS continued

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:

Keep a first aid kit in an easily accessible location on the vehicle at all times.

•

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).

•

Any cloths, residue and gloves must be safely discarded after use.

Working with oil Direct contact with oil implies a risk of skin complaints (example: eczema). Strict hygiene should always be observed.

Some advice which should be observed: •

Oils used in this machine may be hot enough to cause serious burns.

• •

Avoid contact with oil, particularly heated oil.

Oil on the skin should be washed off immediately with soap and water.

Wear protective gloves. Hands should be clean before putting on gloves. Apply protective cream to the hands to make washing easier.

Don't put oily rags in your pockets.

Oil soiled clothing should be changes as soon as possible.

Always keep an extra overall handy, but not in the machine where it can become dirty.

OPERATING SAFETY PRECAUTIONS continued MACHINE STABILITY AND TRACTION MACHINES WITHOUT LEVELLER When working on slopes, travel straight up or down the slope to prevent roll-over.

NEVER travel across a STEEP slope or side hill: •

As a load is added to the attachment the handling and the stability of the machine will change.

•

To avoid tip over, keep the attachment as low as possible to maintain a low center of gravity.

•

Always be prepared to dump the load in case of an emergency.

•

Do not overload the machine as this can create an unstable condition and cause a rollover.

Tigercat H822C/LH830C Harvester

Safety

OPERATING SAFETY PRECAUTIONS continued MACHINE STABILITY AND TRACTION MACHINES WITH LEVELLER 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.

26°

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.

NORMAL WORKING RANGE OF BOOM SYSTEM

FIG. 2 UNDERCARRIAGE LEVELING 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.

•

Always carry any load on the uphill side of the machine.

•

Do not lift or move objects that exceed machine stability.

•

Always be prepared to release the load in case it causes the machine to tip.

•

Always position the cab so that you have a clear view in the direction of travel. Be aware of ground conditions and obstacles in the machine’s path before moving the machine.

•

TRACK GEAR BOX AT REAR OF UNDERCARRIAGE

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 uphill and the attachment should be kept close to the ground (FIG. 3). When descending a slope the boom should face uphill and the attachment should be kept close to the ground (FIG.4). Be aware that the machine is in its least stable position 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.

SERVICING SAFETY PRECAUTIONS continued WARNING Diesel fuel or hydraulic fluid under pressure can penetrate the skin and cause serious personal injury, blindness, or death. If any fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with treating this type of injury.

Explosive release of fluids from pressurized cooling system can cause serious burns.

Shut off engine. Only remove coolant filler cap when cool enough to touch with bare hands.

Slowly loosen cap to first stop to relieve pressure before removing completely.

Never use your bare hand to check for fluid leaks.

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

Fluid leaks under pressure may not be visible.

When searching for leaks, wear work gloves and use a wrench or piece of wood to move hydraulic hoses. Do not grab hold of hydraulic hoses.

Wear safety goggles for eye protection.

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.

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 ). Accumulators will self drain within 2 minutes of stopping the engine on this MODEL. Also, relieve pressure in the hydraulic reservoir by opening hydraulic tank vent valve and waiting until the sound of escaping air stops.

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.

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.

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.

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.

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.

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

5. Remove debris and blow out dust regularly from the air intake doors, engine 1.20

Safety •

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.

FIRE PREVENTION continued 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

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

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

FIRE PREVENTION continued

•

Remain with the machine at a safe distance, 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 21

•

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.

WHAT TO DO AFTER A FIRE •

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

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

•

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.

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.

•

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.

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

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.

It should be noted that the available torque when travelling at maximum speed is only half of that in LOW. The DRIVE position will provide a faster travel speed range but with a lower driving force.

However, when the machine encounters tougher terrain conditions, e.g. stumps, soft ground or slopes etc., the drive system will automatically adjust* to a slower travel speed/ higher torque range. *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 .

11. HORN, SAFETY ALERT - SWITCH This is a two position "momentary" switch.

Press and hold this switch to sound the safety alert horn.

Always use this horn prior to starting the engine and to alert other personnel in the area of your presence.

charge air, engine coolant and/or the temperature of the hydraulic oil. The electronic control module automatically adjusts fan speed to the minimum required level to maintain optimal operating conditions, and default to fan at full speed if an error in the controller exists.

The electronic fan control will also turn the A/C system OFF for as long as the fan is in the CLEAN mode.

When the CLEAN cycle is complete the fan automatically returns to normal rotation direction.

Note: The CLEAN cycle also operates automatically via the timed purge function of the computer control system (frequency is adjustable). Refer also to COMPUTER ~ INFORMATION MESSAGES and COMPUTER ~DIAGNOSTIC ~ ADJUST FUNCTION PARAMETERS in THIS SECTION.

When the switch is in the AUTO position and the fan runs at minimum speed due to low charge air, engine coolant or hydraulic oil temperatures, turning ON the A/C will cause the fan control to increase the cooling fan speed when engine is at high idle. This is to ensure that sufficient air flow is available for the cab A/C even while the machine is still warming up.

CAUTION

FULL ON (OVERRIDE) POSITION - When the switch is in the FULL ON (OVERRIDE) position, the fan control system is overridden and the fan will run at FULL speed for cooling regardless of charge air, coolant or oil temperatures. Normally the fan control switch is placed in the AUTO position for optimal cooling. The FULL ON (OVERRIDE) position is intended for use in the event of a temporary failure of the fan control.

Before placing the fan switch in the CLEAN position make sure that there are no personnel on the REAR of the machine in the area where the fan will expel debris.

AUTOMATIC OPERATION There are 4 thermostats mounted in the engine and hydraulic enclosures which are wired to a control panel. The thermostats are automatic heat detection devices and are set to “close” at 177°C (350°F). When a thermostat closes it sends an electrical signal to the control panel.

NOTE: A pre-delivery inspection of the fire suppression system must be carried out to ensure the system is fully operational. This involves performing all daily and weekly inspection steps. Refer to INSPECTION OF THE AMEREX FIRE SUPPRESSION SYSTEM AND PORTABLE EXTINGUISHERS in THIS SECTION.

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 6 nozzles strategically placed in the engine compartment and hydraulic areas.

Controls and operation

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/pneumatic 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 and all electrical power.

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.

FIRE SUPPRESSION SYSTEM

The system will activate the discharge system and the automatic engine shutdown system.

There will be a cloud of dry chemical dispersed in the discharge area. The engine 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 the portable fire extinguisher in the cab or outside 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.

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.

Controls and operation

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.

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.

For more detailed instructions and information about electronic adjustment of functions refer also to TELESCOPIC BOOM AND PUMP 2 ELECTRONIC ADJUSTMENT PROCEDURE in THIS SECTION. CURRENT OUT (COUT) The COUT channel maintains a constant output current to control proportional solenoids. The voltage is regulated to maintain the constant current based on the resistance of the circuit.

These settings (defined below) fine tune the operating speeds and start/stop ramps for the adjustable current out operated functions.

B. ADJUST INPUTS AND OUTPUTS Adjustable inputs include: •

Proportional Telescopic (Voltage In) (if equipped)

MINIMUM CURRENT Minimum current settings control function start speed. Coils on hydraulic valves require a certain amount of current before they begin to operate the valve. The Min current value is the current that will be sent to the hydraulic valve coil when the function switch is activated.

VOLTAGE IN (VIN) The input signal at these inputs comes primarily from analog sensors, levers, and switches. These devices use a power/signal/ground system to provide an input value (VIN) between the high (+5V) and low (-5V) signals generated in the modules.

The min current is adjusted to a value that causes the function to just begin to move.

C. ADJUST OUTPUTS

MAXIMUM CURRENT Maximum current settings control the maximum speed the function will operate.

Adjustable outputs include: •

Right Level Cylinder (Current Out)

•

Left Level Cylinder (Current Out)

•

Pump 2 - Attachment (PWM Out)

•

Telescopic - Attachment (PWM Out)

START/STOP SLOPE Start and stop slope is the time it will take for the current to rise from minimum to maximum and maximum to minimum respectively.

FINE CONTROL Fine Control changes the current output curve from being a straight line to being close to a type of curved line. Lower numbers create more output. Higher numbers create less output.

Controls and operation

PWM OUT (PWMOUT) PWM (Pulse Width Modulation) Out is a way of producing an analog signal level with a digital output that turns on and off many times a second.

By varying the ratio between on and off time (modulation ratio or duty cycle) an output proportional to the system voltage can be obtained.

PWMOUT maintains a constant output voltage, and the output current is governed by the resistance in the circuit.

Tigercat H822C/LH830C Harvester SYSTEM WARNING MESSAGES When system warning messages are displayed the master alarm may sound, see specific warning message descriptions for details. All system warning messages are logged and recorded by the IQAN system for use by Tigercat service technicians. Operator's should respond to all warning messages immediately by bringing the machine to a safe stop and investigating the cause of the alarm.

The alarm can be acknowledged by pressing OK (F1), if applicable. Note that acknowledging the warning message does not address the cause of the alarm. Ignoring system warning messages may result in component damage and/or subsequent malfunction. In addition ignoring system warning messages may also affect warranty claims. All warning messages should be addressed immediately to help ensure the efficient long term operation of the machine and avoid costly repairs.

Controls and operation

822C-62

MODULE IS OFFLINE SYSTEM WARNING The MODULE IS OFFLINE warning message indicates a loss of communication with or power to an IQAN module. The offline module is identified on the display screen.

When a module goes offline all machine functions controlled by that module cease and all alarms and warnings associated with that module are triggered. If the problem is with the CAN wires all modules beyond the problem module will also be affected.

CAUTION Do not make adjustments in this menu.

Machine service indicators can be affected.

620C-43

NOTE: It is possible for an operator or service technician to disable this warning message. If the MODULE IS OFFLINE warning function is disabled for a module the first indication of a loss of communication or power to a module will be the loss of all machine functions controlled by the module and the triggering of all alarms and warnings associated with that module. This may cause problems in identifying the source of a control problem, as it will not be immediately obvious that a loss of communication or power to the module is the source of the problem.

To greatly reduce the time required to diagnose a MODULE IS OFFLINE warning, it is recommended that all available modules ALWAYS be set to ENABLED as shown. This screen is accessed through the INFORMATION MENU which should normally be accessed by Tigercat service 2.44

Tigercat H822C/LH830C Harvester technicians only. Refer to SECTION 6 of the SERVICE MANUAL for more information.

Note also an exception to the rule: H822C series Harvester programs contain information for all H822C/LH830C models including module programming for the XT2-A0 OC Leveller module (open loop leveller, used only on the L830C and LH830C) and the XT2-A1 CC Leveller module (closed loop leveller, used only on the LX830C).

Depending on the model of machine the program is installed in one or both of these modules will be disabled because the module is not used on the machine. In the case where a newer version of the program and/or a new MDM module has been installed during a service procedure it may be necessary for the service technician to disable the appropriate module(s).

Controls and operation CHECKING LEVELLING SPEED (CYLINDER CYCLE TIMES) 1. Ensure hydraulic oil is at operating temperature.

Adjustments to the levelling system through the PROPERTIES MENU of the IQAN control system electronically adjust the performance of the levelling system to suit operating conditions .

Refer also to COMPUTER ~ (PROPERTIES) MENU OPERATION in THIS SECTION.

2. Ensure no other personnel are in the area during this procedure. Start engine and set throttle speed to HIGH IDLE. 3. Close cab door and press PILOT RESET switch to activate pilot system.

Two types of adjustment can be made to the levelling system:

4. Place ANTI-STALL switch in the OFF position.

CYLINDER OPERATING SPEEDS Forward Level Speed and Rear Level Speed function parameter adjustments provide a means for setting the levelling FORWARD/ BACKWARD cylinder operating speed.

5. Press the REAR tilt levelling switch and fully retract BOTH cylinders.

6. Press the FORWARD tilt levelling switch and fully ** extend cylinders. Record cycle time from stop to stop.

CYLINDER TRACKING The Right Level Cylinder and Left Level Cylinder current out adjustments provide for setting the cylinder operation of both cylinders to prevent tracking (one cylinder extending or retracting faster then the other).

7. Operate the REAR tilt levelling switch and fully ** retract cylinders. Record cycle time from stop to stop.

These settings control the operation of the electrohydraulic spool actuators which control the cylinder tracking and operating speeds by regulating the flow of oil from the levelling control valve to the levelling cylinders.

8. If required, adjust the computer control system settings for forward levelling speed or rear levelling speed to achieve the time outlined in the chart (PROPERTIES ~FUNCTION PARAMETERS). Refer to ADJUSTING FORWARD/REAR LEVEL SPEED in THIS SECTION for procedure.

NOTE: Adjustment of the FORWARD/REAR speed is the setting required to obtain recommended cycle time. SIDE to SIDE speeds will be a product of these settings.

DANGER Extreme care and attention must be exercised when making adjustments to the levelling hydraulic and electrical circuits.

Ensure that all personnel not directly associated with the servicing are well clear of the machine.

The whole upper frame/cab/engine compartment, boom and attachment can tilt unexpectedly from side to side or forward and backwards during servicing, creating "pinch points" between the upper frame and track assembly and the ground.

DANGER

NOTE ALSO: Some fine adjustments may be required to ensure that the upper frame does not track RIGHT or LEFT during the FORWARD/REAR movement. Refer to ADJUSTING CYLINDER TRACKING ~ ADJUSTING MAXIMUM/MINIMUM CURRENT for procedure. ** When extending or retracting cylinders to record the time, stop the cylinder just before it gets to the end of it's stroke rather than let it bottom out and impose unnecessary loads on the cylinder parts and frame structures.

IMPORTANT

NEVER PRE-FILL HYDRAULIC FILTERS

HYDRAULIC OIL FILTERS

Tigercat generally does not recommend the pre-filling of spin-on filters due to the risk of damage to the hydraulic system caused by unfiltered oil. Unfiltered oil used to pre-fill filters enters directly into the hydraulic circuit.

Contaminants in unfiltered oil can cause significant and costly damage to hydraulic valves, pumps and motors. The cleanliness of hydraulic oil cannot be guaranteed unless it is always prefiltered before use.

8. RETURN FILTERS ~ HYDRAULIC OIL 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 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.

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

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

IMPORTANT Contaminated hydraulic fluid can lead to premature failure of hydraulic components and costly repairs.

Filters must be replaced at the recommended time intervals, See SECTION 3 in THIS MANUAL. Use of filters other than genuine Tigercat replacement filters is not recommended.

HAND FILL PUMP

10. HYDRAULIC HAND FILL PUMP The hydraulic hand fill pump, located on the rear left door, is used for adding oil to the hydraulic oil tank. Hydraulic oil is pumped directly into the hydraulic tank via the return filter manifold This ensures that any hydraulic oil added is filtered prior to entering the hydraulic tank. Refer to APPROVED HYDRAULIC OILS ~MAIN HYDRAULIC SYSTEM in SECTION 3 of THIS MANUAL. To add oil to the tank; Depressurize tank, thoroughly clean outside surface of the suction tube and remove the plug. Open the oil fill shut-off valve, insert end of suction tube into supply drum and operate the pump. The oil is pumped directly into the hydraulic tank via the return filter manifold. The pump should always be operated at a medium speed with steady motion. Pumping too fast may cause oil to bypass oil filter.

IMPORTANT: Close shut-off valve, replace cap on suction tube, wipe dry, and store after filling. Failure to keep the suction tube clean will significantly reduce the life of the filter elements. Swing pump handle up and lock.

When searching for leaks, wear work gloves and use a wrench or piece of wood to move hydraulic hoses. Do not grab hold of hydraulic hoses. Wear safety goggles for eye protection.

Tigercat H822C/LH830C Harvester TRAVELLING (BOOM RAISED) 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.

3. Move throttle control to the HIGH idle position.

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

Controls and operation OPERATING TIPS WITH LOAD SENSING When using the controls on a load sensing system think of what the system is trying to do for you. If you move the lever or pedal 20% of its total angle, the system will provide whatever pressure it takes ( up to its maximum capacity if needed) to meet this speed requirement. If you move the lever past the point needed in an attempt to speed up the boom movement, you will only overshoot the speed you wanted. 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 Refer to SET FLOW (FUNCTION SPEED) RATE in appropriate BOOM, SWING or TRACK DRIVE sections of the SERVICE MANUAL.

ATTACHMENT OPERATING INSTRUCTIONS AND SAFETY PRECAUTIONS 1. All tree harvesting should be carried out in LOW driving range. Refer to TRACK, LOW/ DRIVE SWITCH in THIS SECTION. 2. Refer to HARVESTING ATTACHMENT GENERAL SAFETY in SECTION 1 of THIS MANUAL. 3. Read and understand the operating and safety instructions found in the ATTACHMENT MANUFACTURER’S MANUAL for the harvesting head installed on this machine.

Tigercat H822C/LH830C Harvester CARE OF THE MACHINE

Controls and operation 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.

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.

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.

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.

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 attachment raised off the ground. Be sure that the attachment 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 822C and L830C 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.

3. Rinse with clean lukewarm water.

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.

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.

PARKING BOOM FIG.5

NOTE: FULLY RETRACT TELESCOPIC STICK BOOM IF EQUIPPED

Before attempting to disconnect hydraulic hoses or perform work on the boom system, ensure that:-

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) and engine is shut off before disconnecting any hydraulic lines. Also, for machines equipped with pressurized hydraulic tanks, relieve pressure in the hydraulic reservoir by opening hydraulic tank vent valve and waiting until the sound of escaping air stops.

(a) The machine is parked on level ground with the head laying flat on the ground. (b) The hoist cylinder fully collapsed. (fig. 5) (c) The telescopic boom fully retracted (if equipped) and the tip of the stick boom supported at the rotator pin. (d) Do NOT rely on the harvester 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. 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.

RETURN MANIFOLD

••

IMPORTANT

•

NEVER PRE-FILL HYDRAULIC FILTERS 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.

• ••

• • 822C-22

1 - WATER ABSORBING RETURN FILTER (COLOUR BLUE)

HYDRAULIC OIL FILTERS

HYDRAULIC OIL RETURN FILTERS 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.

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.

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 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.

FILTER SERVICE NOTE The filters should be checked/changed when the FILTER BYPASS warning light in the cab comes ON. For service and replacement intervals see SERVICE AND LUBRICATION CHART in THIS SECTION. Changing the filter: 1. Park machine on level ground with attachment resting on the ground. Stop engine.

2. Open rear left enclosure door fully and install safety strut.

HIGH PRESSURE PILOT FILTER 822C-40 HYDRAULIC HIGH PRESSURE PILOT FILTER 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 the pilot filter element will need to be changed at an earlier interval.

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

Refer also to SECTION 5 of the SERVICE MANUAL for more information.

WARNING

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.

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

The most common and most damaging air intake servicing problems are:

218-21B

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.

PRECLEANER

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

NOTE: This does not apply to oil filters.

To ensure maximum engine protection, it is 3.22

Lubrication and Maintenance

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

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.
