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 controlling 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 oper-
ate all functions from the platform control station.
To activate auxiliary power:
1. Position PLATFORM/GROUND SELECT KEY SWITCH to PLAT-
FORM.
2. Position POWER/EMERGENCY STOP switch to ON.
3. Depress and hold footswitch.
