well as the solenoid.
TROUBLE WITH LIFTING OR
LOWERING - Continued
Forks do not lift, motor runs.
Defect in hydraulic system.
Check the oil level in the reservoir
and the oil lines to the lift cylinder
,
and repair as required. If normal,
check the hydraulic pump, and
relief valve. Repair
,
or adjust.
Forks lift, but will not go down.
Defect in hydraulic system
Check lowering control switch in
control head and lowering sole-
noid on valve assembly. Replace
as required
Load will not hold.
a. Oil bypassing internally in control
valve.
Replace valve assembly
.
b. Worn lift cylinder or packing.
Repack cylinder.

motor runs
a. Oil level too low
.
Add oil to reservoir
.
b. Load larger than capacity
.
Refer to nameplate on side of
mast for maximum load capacity.
c. Incorrect stopping distance adjust-
ment.
Change batteries.
Forks creep downward under load
when in a raised position.
Leak in hydraulic system, lift cylinder or
lowering valve.
Check for leaking fitting in hydrau-
lic line and repair as required.
Repack lift cylinder or replace
valve assembly .
MISCELLANEOUS
