3.4 CONTROLS AND INDICATORS

Ground Control Station

DO NOT OPERATE FROM GROUND CONTROL STATION WITH
PERSONNEL IN THE PLATFORM EXCEPT IN AN EMERGENCY.
PERFORM AS MANY PRE-OPERATIONAL CHECKS AND INSPEC-
TIONS FROM THE GROUND CONTROL STATION AS POSSIBLE.
NOTE: When the machine is shut down for overnight park-
ing or battery charging, the emergency stop and
power select switches must be positioned to off to
prevent draining the batteries.
1. Platform/Ground Control Switch
A three position, key-operated power select switch
supplies operating power to the platform or ground
controls, as selected. When positioned to platform,
the switch provides power to the emergency stop
switch at the platform controls. When positioned to
ground, the switch provides power to the ground
control. The ground control emergency stop switch
provides power to the key switch. With the power
select switch in the center off position, power is shut
off to both platform and ground controls.
2. Emergency Stop Switch - A two-position, red, mush-
room-shaped emergency stop switch, when posi-
tioned to ON with the power selector switch
positioned to ground, furnishes operating power to
the ground control station. In addition, the switch
can be used to turn off power to the function con-
trols in the event of an emergency. Power is turned
on by pulling the switch out (on), and is turned off by
pushing the switch in (off).
