5.4 EMERGENCY CONTROLS AND THEIR
LOCATIONS
Power/Emergency Stop Switches
1. There are red mushroom shaped switches located at the
Ground Control box and the platform Control panel. The
red switch is pulled up for normal machine operation. In
an emergency, push the button down with the palm and
the machine will immediately stop.
CHECK MACHINE DAILY TO MAKE SURE EMERGENCY STOP SWITCH IS
OPERATIONAL 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 control-
ling the platform level, boom and swing functions from the
ground. Place the KEY 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 electri-
cally driven auxiliary hydraulic pump. This should be used in
case of failure of the main power plant. The auxiliary pump
will operate all functions from the platform control station.
To activate auxiliary power:
1. Position PLATFORM/GROUND SELECT KEY SWITCH to
PLATFORM.
2. Position POWER/EMERGENCY STOP switch to ON.
3. Depress and hold footswitch.
4. Operate appropriate control switch, lever or controller
for desired function and hold.
