WHEN THE MACHINE IS SHUT DOWN THE MASTER/EMERGENCY
STOP SWITCH MUST BE POSITIONED TO THE “OFF” POSITION
TO PREVENT DRAINING THE BATTERY.
1. Master Switch.
A two-position key operated switch furnishes bat-
tery power to the platform to the platform or ground
control switches when station power is selected
from the ground control panel and the master
switch is turned “ON”.
2. Control Station Selector.
A three position, center off, key activated PLAT-
FORM/GROUND SELECT switch supplies power to
the platform control console when positioned to
PLATFORM. With the switch in the GROUND posi-
tion, power is shut off to the platform station, and
only the controls on the ground control panel are
operable.
NOTE: With the Platform/Ground Select Switch in the center
position, power is shut off to controls at both operat-
ing stations.
TO AVOID SERIOUS INJURY, DO NOT OPERATE MACHINE IF ANY

3. Ignition.
The machine is equipped with an on-off ignition
switch and a separate start push button switch on
the ground control panel which supplies electrical
power to the start solenoid when the ignition switch
is placed in the ON position and the START button
is depressed.

energizes the electrically operated auxiliary hydrau-
lic pump, when actuated. The switch must be held
in the ON position for the duration of auxiliary pump
