Body Control
This lever operates the body hoist cylinders. The four operating positions of the
lever are -
Raise - Pushing the lever back and holding it in this position will raise the body.
When released, the lever will spring back to the 'HOLD' position.
Hold - This position stops and holds the body at any desired height. The lever
will remain in the 'HOLD' position when released.
Power Down - Pushing the lever forward and holding it in this position provides
hydraulic force to power-down the body. When released, the lever will spring
back to the 'HOLD' position.
Float - The control lever should remain in this position until the body is to be
operated again. The control lever should always be kept in 'FLOAT' while the
machine is in motion.
Note: The body control lever must remain in the 'FLOAT' position until it is
necessary to operate the body again. Failure to comply to this could result in
overheating the hydraulic oil and failure of the hydraulic system components.
Note: A proximity sensor prevents the body being fully powered down onto the
chassis. At a predetermined height, the sensor automatically defaults the body
control valve to the detented 'FLOAT' condition.
Note: If an electrical failure occurs, the body control valve will automatically
default to the 'HOLD' condition. The cause of the electrical fault must be
investigated and corrected.
