MAINTENANCE
91
Do the following checks and inspections:
a. Check for leaks in the hydraulic system. Check the
condition of the hydraulic hoses and tubes.
b. Slowly raise and lower the mast several times with-
out a load. Raise the mast to its full extension
height at least once. The mast components must
raise and lower smoothly in the correct sequence.
NOTE:
Some parts of the mast move at different speeds
during raising and lowering.
c. The inner weldment and the carriage must lower
completely.
d. Raise the mast one metre (three feet) with a capac-
ity load. The inner weldment and the carriage must
raise smoothly. Lower the mast. All moving compo-
nents must lower smoothly.
e. Lower the load to approximately 0.3 metre (one
foot) from the floor. Tilt the mast forward and back-
ward. The mast must tilt smoothly and both tilt cyl-
inders must stop evenly.
f. Check that the controls operate the functions of the
attachment correctly. (See the symbols next to
each of the controls.) Make sure all of the hydraulic
lines are connected correctly and do not leak.
Brakes
Check that the service and parking brakes operate cor-
rectly. The service brakes must apply when the brake
pedal is depressed. The parking brake must apply or re-
lease with the knob movement described on page 14. On
lift trucks with a Monotrol pedal, applying the parking
brake puts the transmission in NEUTRAL.
NOTE:
Full application of the inching/brake pedal applies
the service brakes and disengages the transmission.
Steering System
WARNING
The lift truck has hydraulic power steering. The steer-
ing can be difficult if the engine is not running.
Make sure the steering system operates smoothly and
gives good steering control.
