Hydraulic Control Levers
Check that the hydraulic control levers for the mast
and attachment operate as described in the Oper-
ating Manual. Lubricate manual control levers as
necessary. See the Maintenance Schedule.
Direction and Speed Control Pedals
Check that the direction and speed control pedals op-
erate as described in the Operating Manual. Lubri-
cate the direction lever and accelerator pedal joints
as needed. See the Maintenance Schedule.
Lift System Operation
WARNING
NEVER work under a raised carriage or forks.
Lower the carriage or use chains on the mast
weldments and carriage so they cannot move.
Make sure the moving parts are attached to a
part that does not move.
Do not try to locate hydraulic leaks by putting
hands on pressurized hydraulic components.
Hydraulic oil can be injected into the body by
pressure.
1.
Check for leaks in the hydraulic system. Check
the condition of the hydraulic hoses and tubes.
NOTE:
Some parts of the mast move at different
speeds during raising and lowering.
2.
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).
3.
The inner and intermediate weldments and the
carriage must lower completely.
4.
Raise the forks 1 m (3 ft) with a capacity load.
The inner weldment and carriage must raise
smoothly. Lower the forks. All moving compo-
nents must lower smoothly.
5.
With the load lowered, tilt the mast backward
and forward. The mast must tilt smoothly and
both tilt cylinders must stop evenly.
6.
Check that the controls for the attachment op-
erate the functions of the attachment. See the
symbols by each of the controls. Make sure all of
the hydraulic lines are connected correctly and
do not leak.
Oil Leaks
Visually check the hydraulic system, steering sys-
tem, brake system, and differential for leaks.
Seat Switch
WARNING
Always make sure the parking brake is fully ap-
plied before leaving the lift truck. If the oper-
ator leaves the lift truck without applying the
parking brake, a seat activated switch will cut
off power to the lift truck.
There is a switch in the seat that senses the presence
of the operator. The operator must be in the seat
before turning the key switch ON to provide power
to the lift truck. See Figure 12.
If the operator leaves the seat while the truck is mov-
ing, the seat switch will cut off power to the lift truck.
If the seat switch is damaged, see Electrical Sys-
tem (Trucks With AC Controllers) 2200 SRM
1055 for replacement procedures.
