cylinders and the hoist valve will default to
HOLD. The operator will position the hoist
lever to HOLD. The midpoint stop value is set
prevent the tailgate of the container from
contacting the ejected load or the ground. This
safety feature will prevent damage to the body
assembly and the tailgate.
If the load is not fully ejected from the container
the operator may raise the bed further. This is
accomplished by positioning the hoist lever to
the HOLD position, depress and hold the
midpoint override switch and move the hoist
lever to the RAISE position then release the
override switch. The body will continue to raise
to the upper limit angle value as programmed
into the ECM software.
The midpoint stop and the upper raise limit
angles can be programmed as specified by the
type
of container and the end users
requirements.
LOWERING THE BED ASSEMBY
The operator moves the hoist control lever to
LOWER position. The chassis ECM commands
the hoist valve to provide pressure to the lift
cylinders and the bed begins to lower. Once the
bed assembly is down operators should position
the hoist lever to FLOAT. Once the container
doors are closed manually, the operator should
depress the stinger CLOSE button from the
remote switches to command the stinger to raise
and restrain the tailgate. The stinger can also be
operated by the hoist control lever when the
vehicle is moving forward at 7 mph or greater
and the hoist lever is placed in the LOWER
position. This action will allow hoist valve
LOWER oil pressure through the stinger
activation control valve and CLOSE the stinger.
When the stinger is in the full CLOSE position
the operator can move the hoist lever to the
FLOAT position.
