4.1

DESCRIPTION

This machine is a self-propelled hydraulic 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 upper or lower boom or swing the boom to the left or
right. Standard boom swing is 360 degree continuous left and
right of the stowed position. 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 oper-
ator in the platform be unable to do so. The Ground Control is
also to be used in Pre-Start Inspection.
