6.3 EMERGENCY CONTROLS AND THEIR
LOCATIONS
Emergency Stop Switches
There is an emergency stop switch at both the Ground
Controls and Platform Controls. When positioned to OFF it
will immediately stop the machine.
CHECK MACHINE DAILY TO MAKE SURE EMERGENCY STOP
SWITCH GUARD IS IN PLACE AND THAT GROUND CONTROL
INSTRUCTIONS ARE IN PLACE AND LEGIBLE.
Ground Control Station
The Ground Control Station is located on the right front
side of the turntable. The controls on this panel provide
the means for overriding the platform controls, and for
controlling the platform level, boom and swing functions
from the ground. Place the SELECT switch to GROUND
position and operate the proper switch to lift, swing, or
telescope the boom, or level the platform.
Auxiliary Power
A toggle type auxiliary power control switch is located on
the platform control station and another is located on the
ground control station. Operation of either switch turns on
the electrically driven auxiliary hydraulic pump. This
should be used in case of failure of the main power plant.
The auxiliary pump will operate boom lift, telescope and
swing. To activate auxiliary power:
1. Position the platform/ground SELECT SWITCH to
PLATFORM.
