SECTION 4. MACHINE OPERATION
4.1 DESCRIPTION
This machine is a self-propelled hydraulic lift equipped with a
work platform on the end of an elevating, articulating and rotat-
ing 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 boom or swing the boom to the left or right. Standard
boom swing is 360 degree non 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 emer-
gency to lower the platform to the ground should the operator in
the platform be unable to do so. The Ground Control is also to be
used in Pre-Start Inspection.
