OPERATION
Platform/Ground Select Switch
The power selector switch functions to direct electrical
power to the desired control station. With the switch in the
ground position, power is supplied to the emergency stop
switch at the ground control station. When the switch is in
the platform position, power is supplied to the emergency
stop switch at the platform control station. The switch
should be in the off position when parking the machine
overnight.
Emergency Stop Switch
This switch, when in the on (out) position, provides electri-
cal power to the ground controls or platform controls, as
applicable. In addition, the switch can be used to turn off
power (push the switch IN) to the function controls in the
event of an emergency.
