5-2. DIRECT SUPPORT TROUBLESHOOTING (continued).
LHS CREEPS UNDER LOAD (continued).
LHS LOAD TEST
The LHS will creep in the direction that
gravity is pushing the LHS components and
payload. Depending on the position of the
LHS components, the weight will try to push
the LHS into the loaded (retracted) or un-
loaded (extended) positions.
Additional weight on the LHS will magnify a
creeping problem. Therefore, this fault will
be easier to diagnose using a payload rather
than an empty LHS.
Refer to Chapter 2 for specific LHS operat-
Turn LHS MODE SELECT switch to AUTO
Unload LHS until hook arm hydraulic cylinders are
extended approximately one foot.
Turn LHS MODE SELECT switch to OFF position.
Watch hook arm and hook arm hydraulic
cylinders for movement.
