AUXILIARY POWER OPERATION

The Auxiliary Power System provides a means of moving the platform in the event of an
engine malfunction. This system uses an electric motor/pump unit capable of operating
all boom functions needed to allow the platform to be lowered to ground level.
With auxiliary power activated, the control system will attempt to use the force of
gravity to operate main lift down, tower lift down, and tower telescope in. If appropriate
movement is not detected by the boom sensors, the auxiliary power system will supply
hydraulic flow to power boom movement. Allow sufficient operating time for system to
respond.
