LHS OVER

LOAD Indicator

(M1120 only)

Illuminates (yellow) whenever main hydraulic relief valve is

opened during loading or unloading. When light illuminates,

driver will be warned that LHS has reached an overload

condition or that hydraulic system is lifting very near

maximum capacity. OVER LOAD indicator will come on any

time main relief valve is cracked open, therefore, load or

unload operation may not come to a complete stop, but light

will come on momentarily. This situation would indicate that

system is lifting near maximum capacity. If the LHS is

overloaded, the light illuminates and the system is

automatically blocked out. Off-load/on-load flatrack, and

attempt second operation. If, during this second attempt, the

LHS shuts down, stop operation and redistribute weight or

reduce payload before attempting load or unload. When

attempting to load/unload Forward Repair System (FRS),

manual procedures must be followed or LHS overload system

will shut down the LHS system.
