Operation and maintenance manual

5-7
Before raising the body, make sure that the rear wheels are on firm level
ground. If one wheel is higher than the other, a twisting strain is imposed upon
the body hinge pins, hoists and chassis. Stop the machine, allow the engine to
slow to idle, shift the transmission to 'NEUTRAL' and apply the brakes with the
Parking-Emergency Brake control, to hold the machine stationary.
Push the body control lever back into the 'RAISE' position and accelerate 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 '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.
Never 'JUMP DUMP' the machine by bouncing the rear tyres against a stop
block, or otherwise jarring the body in its raised position, to dislodge stuck or
frozen material. The tremendous loads 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 forward into the 'POWER
DOWN' position and accelerate the engine. As the hoists approach their fully
retracted positions, decelerate the engine and push the body control lever fully
forward into the 'FLOAT' position, allowing the body's weight to lower it to the
chassis. A proximity sensor prevents the body being fully powered down
hydraulically, at a predetermind body height, the sensor will automatically default
the body control valve to the detented 'FLOAT' condition.
