DESCRIPTION

This machine is a mobile elevating work platform used to posi-
tion personnel, along with their necessary tools and materials at
work locations.
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 all functions except drive and steer.
Except for performing inspections and the Function Check, the
ground controls are used in an emergency to lower the platform
to the ground should the operator in the platform be unable to
do so.
