Platform Control Descriptions:
When platform/ground control select switch is switched to

platform control panel. The controls are activated through
either push-buttons or toggle switches, whose functions are
marked with symbols and / or written text.
1. Engine Start Switch - Toggle switch that turns the diesel
engine on and off. Up for on, down for off.
2. Emergency Stop Button - Button, when depressed, will
immediately shut the machine off. Cuts out all functions
except emergency platform lowering.
3. Deck Extension/Drive/Lift Select Switch -3 position tog-
gle switch that selects the functions of platform exten-
sion, drive or lift. Up for platform extension, middle for
drive, and down for lift. Works in conjunction with the
joystick controller.
4. Drive Speed Switch - 3 position toggle switch that
selects between fast drive, slow drive or posi-traction.
Posi-traction evenly distributes the torque between all
four wheels to provide better traction in situations that
require it.
5. Lift/Drive/Deck/Steer Controller - The Controller works in
conjunction with the platform extension, drive and the lift
switch depending upon which function is selected. The
button on the front of the joystick is the enable button.
This button must be held in to work all joystick con-
trolled functions. When the Drive function is selected,
moving the joystick forward and backwards operates
the forward and reverse movement of the machine. The
switch on top of the joystick controls the steering of the
machine when the Drive function is selected. When the
Deck function is selected, moving the joystick forward
and backward extends and retracts the platform deck
extension. When the Lift function is selected, moving
the joystick forward and backwards raises and lowers
the platform.

drive is enabled. The LED goes out when the platform is
above the maximum drive height of 69 ft (21 m), or with
outriggers selected and deployed.
8. Glow Plug Enabled or Active LED - This Yellow LED is off
under normal operating conditions. The LED is illumi-
nated when the ignition is on and the temperature sens-
ing requires pre-glow.
NOTE: Do not start machine when Glow Plug LED is illuminated.
Once the LED goes out, machine starting is permitted.
