Operating Instructions (Cont)
2-9. LOAD HANDLING SYSTEM (LHS) (CONT).
CAUTION
·
Engine speed must be at idle before using hydraulic selector switch, or damage to
equipment may result.
·
To avoid equipment damage, ensure that main frame cylinders do not complete full
extension while operating at engine speeds above idle.
·
Manual mode is used mainly in event of a failure of automatic control electrical
system. Greater care must be exercised during operation of MANUAL mode for
correct cycle of events to occur or damage to equipment may result.
·
If LHS had previously been used in manual mode and not completely stowed in
AUTO mode, the hook arm cylinders must be completely extended or the LHS must
be completely stowed using AUTO mode before the flatrack can be loaded. Failure to
comply may result in damage to the truck and flatrack.

LHS will only operate when transmission range selector is in N (Neutral).
