MAST OPERATION
Sound horn, and actuate the lift and tilt levers to be
certain that the carriage moves up and down properly
and the mast can be tilted smoothly.
Make certain that the relief valve operates accompanying
its relieving sound when each cylinder piston reaches
the stroke end. Pay attention to system operating sound.
CAUTION
- WARM UP CYLINDERS-
Warm up the hydraulic cylinders
before putting the truck to work.
This lubricates the packings and
seals in the cylinders to get them
ready for operation.
CAUTION
Don’t tilt the mast forward while the
carriage is lifted high, especially
when a clamp attachment is fitted to
the truck.
LIFT CHAIN TENSION CHECK
Check the tension and abnormality of the lift chains. To
check the tension, raise the fork about 5cm (1.97
inches) above the ground and push the middle of the
chain with the thumb. Make certain the tension for the
right and left chains is even. If uneven tension is found,
loosen the lock nut of anchor pin and adjust the chain,
turning the adjusting nut of the chain anchor pin.
CAUTION
Don’t use "Grease" but "Machine Oil
(ex. Hydraulic Oil)" only for lift chain
lubrication. SAE 50w is normally
recommended except for extremely
cold areas.
EXHAUST GAS CHECK
Check condition of exhaust gas after the engine warm-
up is finished.
Colorless or bluish:
Normal - Complete combustion
Black:
Abnormal - Incomplete
Combustion
White:
Abnormal - Oil Consumption Check also the engine
and driving system for clicking or any abnormal noise or
vibration.
WARNING

the
lift
truck

leave waste cloth or paper inside the
engine room. Make sure you know
where the fire extinguishers are kept
and how to use them.
