30 MAST OPERATION
Operate each of the lift and tilt levers in full stroke a few
times to check if the forks and mast operate smoothly
without squeaking. Check also each lever for looseness.
(If the truck is equipped with an optional hydraulic
attachment, check the attachment itself and its control
lever.)
NOTE
WARMING UP CYLINDERS
Before starting the day’s work, warm up the cylinders.
This lubricates packings and seals in the cylinders to
make them ready for operation.
31 LIFT CHAIN TENSION
Raise the forks 50 mm (2 in.) off the ground or floor
surface and check that the right and left lift chains have
the same tension.
If uneven tension is found, adjust the tension using the
adjusting nut of the chain anchor bolt. After adjustment,
securely tighten the lock nut.
In addition, check the chains for deformation, corrosion
or damage.
32 STEERING WHEEL
Turn the steering wheel counterclockwise and clockwise
to check for play.
The normal play is within the range of 15 to 30 mm (0.6
to 1.2 in.). Check also for vertical looseness.
NOTE
Steering wheel play should be checked with the
engine running.
