Working the Machine
5-7
Push the body control lever back into the 'RAISE' position and accel-
erate the engine. Decelerate the engine to slow the raising speed as
the hoists approach their maximum extension. When the body has
been raised to the desired height, release the control lever into the
‘NEUTRAL’ (Hold) position until the body is to be lowered. Do not hold
the lever in the 'RAISE' position when the hoists are fully extended to
prevent unnecessary hydraulic system relief valve operation.
NOTICE: Never 'JUMP DUMP' the machine by bouncing the rear tyre
against a stop block, or otherwise jarring the body in its raised posi-
tion, to dislodge stuck or frozen material. The tremendous stress that
this practice develops on the body pin area, chassis and hydraulic
system can cause needless, extensive stresses.
Once the load has been dumped, push the control lever fully forward
into the detent ‘POWER DOWN’ position and accelerate the engine.
As the hoists approach their fully retracted positions, decelerate the
engine. At a predetermined body height a proximity sensor causes
the body control lever to spring back to ‘NEUTRAL’ position, allowing
the body to float onto the chasis under it’s own weight.
Empty Return
Make sure the body is completely lowered, the body control lever is in
the 'NEUTRAL' position and transmission is in the correct gear range
before releasing the brakes and moving away from the dump site.
Except for the above, the procedure for returning empty to the loading
area is the same as that given earlier for 'HAULING'.
