DESCRIPTION

This machine is a self-propelled hydraulic personnel lift
equipped with a work platform on the end of an elevating
and rotating boom.
The primary operator control station is in the platform.
From this control station, the operator can drive and steer
the machine in both forward and reverse directions. The
operator can raise or lower the main or tower boom or
swing the boom to the left or right. Standard boom swing
is 360 degree continuous left and right of the stowed posi-
tion. The machine has a Ground Control Station which will
override the Platform Control Station. Ground Controls
operate Boom Lift and Swing, and are to be used in an
emergency to lower the platform to the ground should the
operator in the platform be unable to do so.
