SECTION 4. MACHINE OPERATION
4.1
DESCRIPTION
This machine is a 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. The
operator can control drive, steer, boom/platform functions
and outriggers. The machine has a Ground Control Station
which will override the Platform Control Station. Ground
Controls operate boom and platform functions. They 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 station is to be used for a Pre-Start
Inspection too.
This machine is equipped with an ALL MOTION alarm warn-
ing system to alert other personnel in the work area of any
machine movement during operation. The motion alarm
system is activated during machine function movement
such as track, boom, or outrigger operation.
