Hydraulic Leaks
WARNING
Always wear the proper protective equipment in-
cluding eye protection and petroleum-resistant
gloves when handling hydraulic oil. Thoroughly
wash oil from exposed areas of skin as soon as
possible.
Completely lower forks to relieve hydraulic pres-
sure before disassembling any part of the lift
pump or disconnecting any hydraulic hoses.
The hydraulic oil is hot at normal operating tem-
peratures. Be careful when draining the oil.
Never check for leaks by putting hands on hy-
draulic lines or components under pressure. Hy-
draulic oil under pressure can be injected into the
skin.
CAUTION
Protect the hydraulic system from dirt and con-
taminants when servicing the hydraulic system.
Never operate the pump without the proper
amount of oil in the hydraulic system. The opera-
tion of the hydraulic pump with low oil levels will
damage the pump.
Check for leaks by looking for oil under the lift
truck and where the lift truck has been parked.
Visually inspect the hydraulic system and hoses.
Small oil leaks may appear as wet, oily leaks or un-
usually dirty areas where dirt and dust sticks to oil
that has slowly leaked out.
Drive Tire, Load Wheels, Casters, and Frame
WARNING
When the drive tire has been installed, check all
wheel nuts after 2 to 5 hours of operation. When
the nuts stay tight after an 8-hour check, the inter-
val for checking the torque can be extended to
500 hours. Refer to the Maintenance Schedule in
this section.
If the drive tire has recently been installed, check
to ensure the lug nuts are properly tightened to
140 N•m (103 lbf ft). When installing, snug all the
nuts, then tighten to half the torque value, then
tighten to the full torque value. Tighten the nuts in
a cross pattern to properly seat the wheel to the
hub.
Inspect the tire for embedded rocks, glass, wire,
pieces of metal, holes, cuts, and other damage. See
Figure 11. Remove any object that will cause dam-
age. Check for loose or missing nuts and broken
studs. Remove any wire strapping or other material
that is wrapped around the axle to prevent damage
to the axle seal.
Inspect the frame for structural damage and loose/
missing hardware. Make certain all covers are in
place and secured before operating the lift truck.
Inspect the load wheels. Loose or crooked load
wheels may indicate a bearing failure. If failure is
suspected, raise the lift truck slightly and check
that the load wheels are secure on the axles and ro-
tate smoothly. See How to Put a Lift Truck on
Blocks . Repair or replace as necessary.
