Paper Application

Vehicles used in paper applications require regular inspection and cleaning to minimize the risk of fire.

This should be done at least once every 8 hours or more frequently depending upon operating environment.

The paper application will help limit the contact of paper or tissue scraps to hot surfaces under the hood, but frequent maintenance is required.

WARNING:Engine and exhaust system components are hot to the touch. Be sure lift truck components are cool before starting inspection and cleaning, or personal injury may occur.

Ensure the truck engine cools properly by allowing it to idle for several minutes.

Shutting the truck down while hot will not allow the engine to cool quickly due to the loss of coolant circulation.

The heat trapped under the hood may actually increase the engine temperature because of no heat transfer through the radiator.

With engine OFF and lift truck components cooled, check and clean the radiator and if equipped, radiator screen.

WARNING: Compressed air can move particles so that they cause injury to the user or to other personnel. Make sure that the path of the compressed air is away from all person- nel. Wear protective goggles or a face shield to prevent injury to the eyes.

CAUTION: Air pressure, nozzle, or extension tube may cause damage to exhaust wraps and radiator fins. Assure that air pressure, nozzle, or extension tube does not dam- age exhaust wraps or radiator fins.

Paper removal can generally be accomplished using a compressed air line and nozzle. An extension may be helpful to access hard to reach places.

Remove floor plates and side covers for better access to engine compartment. Open or remove belly pan, if equipped.

Clean components with compressed air.

Take care to maintain the integrity of the exhaust wraps when cleaning with compressed air and use caution to not force debris into openings.

WARNING: Be careful when cleaning with steam. Steam can cause serious burns. Wear protective clothing, gloves, and eye protection. Never expose your skin to steam.

If compressed air did not adequately remove debris, steam clean to remove any persistent accumulation of material or oil.

Protect electrical components from moisture when steam cleaning.

Do not spray exhaust wraps directly with high pressure steam. Allow lift truck to air dry before return- ing to work in a contaminated environment

Paper dust and scraps will adhere to wet surfaces.

CHECK FOR LEAKS - FUEL, OIL, WATER

WARNING: All fuels are very flammable and can burn or cause an explosion. Do not use an open flame to check the fuel level or to check for leaks in the fuel system. If there is a leak in the fuel system, extra care must be used dur- ing the repair. Do not

Make a visual check for leaks on and under the lift truck. If possible, find and report the leak to maintenance for repair.

Leaks often indicate a need for repair of damaged or worn components.

Leaks in the LPG fuel system are usually not visible unless ice is present. There is however, usually a strong odor.

Fuel leaks MUST be repaired IMMEDIATELY.

Check the fuel system for leaks and the condition of parts.

When fuel is added to the lift truck, see the section, How to Add Fuel to the Lift Truck.

Also check the condition of the radiator or heater hoses that are not leaking.

Soft or cracked hoses need to be replaced before a major leak occurs.

HYDRAULIC HOSES

Check the condition of the hydraulic hoses for serviceability by inspecting for cracks or other obvious damage.

Check to insure that the hydraulic hoses are not leaking. If any hose is leaking, report it to maintenance for repair.

COOLANT HOSES

Check the condition of the coolant hoses for serviceability by inspecting for cracks or other obvious damage.

Check to insure that the coolant hoses are not leaking. If any hose is leaking, report it to maintenance for repair.

Indicator Lights, Horn, Fuses, and Relays

If lift truck is equipped with a key switch, turn key to ON position.

If lift truck is equipped with a Power ON/OFF but- ton, press button to turn system power on.

Check all indica- tor lights for correct operation as described in Table 4

Check the operation of the horn.

Start the engine by turning the key switch to the START position, if truck is equipped with a key switch, or press the engine start button, if truck is equipped with this button.

If any of the indicator lights do not operate correctly, stop the engine and check the fuses.

The fuses are located in the Power Distribution Module (PDM) which is under the hood next to the battery on the right side. See Figure 48.

SERVICE BRAKES

Brake Fluid Level

WARNING: Small amounts of water in the brake system can cause reduced braking performance if the water reaches the wheel cylinder area. Do not allow water entry, ensure that the sealed reservoir lid is properly replaced.

If the brake system has a power assist (or boost), brak- ing will be more difficult if the engine is not running.

On lift trucks with wet brake drive axles, only use Dex- ron III oil from sealed container in the master cylinder. On lift trucks with dry brake drive axles, only use SAE J-1703 (DOT 3) brake fluid in the master cylinder.

Loss of fluid from the brake fluid reservoir indicates a leak. Repair the brake system before using the lift truck. Replace the brake fluid in the system if there is dirt or water in the system.

Failure to observe the above warnings could result in death or serious injury.

There is an indicator light on the Display Switch Cluster for the brake fluid.

The red light is ON when the key switch is in the START position or the Power ON/OFF button is pressed, and must go OFF when the engine is running.

If the light is ON when the engine is running, the brake fluid level in the reservoir is too low.

Check the operation of the service brakes.

Push on the inching/brake pedal. The service brakes must be applied before the inching/brake pedal reaches the floor plate.

The pedal must stop firmly and must not move slowly down after the brakes are applied.

The service brakes must apply equally to both drive wheels.

The service brakes must not pull the lift truck to either side of the direction of travel when they are applied.

The service brakes are automatically adjusted when the transmission is in reverse and the lift truck is moving and the brakes are firmly applied.

Full application of the inching/brake pedal applies the service brakes and puts the transmission in NEUTRAL.

Lift trucks with a pedal

when the inching/brake pedal is fully applied, the engine can be started.

Parking Brake

Make sure the service brakes are adjusted and the opera- tion of the automatic adjuster mechanism is correct before the parking brake is adjusted.

Lift trucks with a pedal:

A switch energizes the seat warning circuit when the hand lever is released.

This switch puts the transmission in NEU- TRAL by de-energizing the direction solenoid.

There is also a switch on the left-hand side of bracket. This switch pre- vents engine from starting unless parking brake is applied.

NOTE: Make sure parking brake is released before making adjustment.

To adjust the parking brake, do the following:

Turn the adjustment knob as shown in Figure 49. Do not tighten the adjustment so that the brake is applied when the lever is released. The lever for the parking brake has a lock. Use your thumb or finger to release the lock on the lever when the parkin

For burnished brakes, test the operation of the parking brake. The lift truck, with a capacity load, must not move when parking brake is applied on a 15% grade. A 15% grade is a slope that increases 1.5 m in 10 m (1.5 ft increase in 10 ft).
