Platform Control Station
ONLY USE THE PLATFORM LEVELING OVERRIDE FUNCTION FOR
SLIGHT LEVELING OF THE PLATFORM. INCORRECT USE COULD CAUSE
THE LOAD/OCCUPANT TO SHIFT OR FALL. FAILURE TO DO SO COULD
RESULT IN DEATH OR SERIOUS INJURY.
1. Platform Leveling Override
A three position switch allows the operator to adjust the
automatic self leveling system. This switch is used to
adjust platform level in situations such as ascending/
descending a grade.
2. Drive/Steer Controller
The DRIVE/STEER controller operates two functions:
Drive and Rear Steer. Positioning the controller handle
forward operates Drive Forward, and positioning the
handle to the rear operates Drive Reverse. The rocker
switch on top of the controller handle operates the steer
function for the rear wheels. Depressing the left side of
the rocker switch will cause the machine to steer to the
left, and depressing the right side of the rocker switch
will cause the machine to steer to the right.
WHEN DRIVING FORWARD AND OPERATING THE REAR STEER
WHEELS, THE REAR WHEELS WILL TURN IN THE OPPOSITE DIRECTION
OF MACHINE TRAVEL, I.E., DEPRESSING THE LEFT SIDE OF THE
ROCKER SWITCH WILL CAUSE THE WHEELS TO TURN TO THE RIGHT.
3. Tower Telescope Controller
The TOWER TELESCOPE controller provides extension
and retracting of the tower boom when positioned to IN
or OUT.
4. Start Button
The START button is a momentary contact, push button
type switch. With the MASTER SWITCH positioned to
ON and the START button depressed, electrical power is
supplied to the starter solenoid.
5. Choke/Glow Plug Switch (If Equipped)
The optional CHOKE/GLOW PLUG switch is used to
assist cold engine starting. For diesel engines, the
switch activates glow plugs in the engine to warm the
diesel fuel for easier starting. On gasoline engines, the
switch activates the choke to deliver a richer fuel mixture
for easier starting.
