and wheel assembly completely to its right hand stop using
the steering wheel. The steering system should move
smoothly and make a full range of motion from its full left to
full right position (approximately 180 degrees).
Hydraulic System
WARNING
At operating temperature the hydraulic oil is HOT. DO
NOT permit the oil to contact the skin and cause a
burn.
WARNING
Always wear the proper protective equipment including
eye protection and petroleum-resistant gloves when
handling hydraulic oil. Thoroughly wash oil from
exposed areas of skin as soon as possible.
CAUTION
DO NOT permit dirt to enter the hydraulic system when
the oil level is checked or the filter is changed.
Never operate the pump without oil in the hydraulic
system. The operation of the hydraulic pump without
oil will damage the pump.
NOTE: Some parts of the mast move at different speeds
during raising and lowering.
Slowly raise and lower the mast several times without a
load. The mast components must raise and lower smoothly
in the correct sequence. The carriage raises first, then the
inner weldment and intermediate weldment (three-stage
masts only).
The inner and intermediate weldments and the carriage
must lower completely.
Raise the forks 1 m (3 ft) with a capacity load. The inner
weldment and carriage must raise smoothly. Lower the
forks. All moving components must lower smoothly.
With the load lowered, tilt the mast backward and forward.
The mast must tilt smoothly and both tilt cylinders must
stop evenly.
Check that the controls for the attachment operate the
functions of the attachment. See the symbols by each of
the controls as shown in Table 4. Make sure all of the
hydraulic lines are connected correctly and do not leak.
