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 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 non-continuous left
and right of the stowed position. The machine has a Ground Con-
trol 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.
