DESCRIPTION
This machine is a self-propelled hydraulic lift equipped with a
work platform on the end of an elevating and rotating mast.
The primary operator control station is in the platform and shall
only be accessed with the extending structure fully stowed.
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 mast and the jib or swing the mast to the
left or right. Standard mast swing is 172.5 degree left and right
of the stowed position. The machine has a Ground Control Sta-
tion which will override the Platform Control Station. Ground
Controls operate mast and jib 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. The Ground Control
is also to be used in Pre-Start Inspection.
