SECTION 4. MACHINE OPERATION
4.1 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 opera-
tor can raise or lower the upper or lower 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 Upper
and Lower 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.
