SECTION 4. MACHINE OPERATION
4.1
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 console is in the platform. From this
control console, 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 continuous rotation. The machine has
a Ground Control Console which will override the Platform Con-
trol Console. Ground Controls operate 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.
4.2
HYDRAULIC SYSTEM WARM UP
The control system monitors the hydraulic system in extremely
cold temperatures and provides optimal performance by auto-
matically limiting the function speeds of the high demand func-
tions. The warm up mode automatically shuts off when system oil
reaches allowable temperatures.
While the system is cold and in the warm up mode, the tower lift,
main lift, and main telescope functions are limited to creep
speeds and is indicated to the operator by flashing the creep light
on the platform control panel.
Functions being operated when the warm up mode turns off will
remain in the creep speed until the function is re-initiated.
