Platform Station - Prior to September 1991
(Standard Machines)
NOTE: For engine starting, the footswitch must be in the
released (up) position. Footswitch must be actuated
in order for controls to function.
1. Footswitch.
This feature makes it necessary to depress the foot-
switch to allow operation of the controls.
TO AVOID SERIOUS INJURY, DO NOT REMOVE, MODIFY OR DIS-
ABLE THE FOOTSWITCH BY BLOCKING OR ANY OTHER MEANS.
THE FOOTSWITCH MUST BE ADJUSTED SO THAT FUNCTIONS
WILL OPERATE WHEN THE PEDAL IS APPROXIMATELY AT ITS
CENTER OF TRAVEL. IF THE SWITCH OPERATES WITHIN LAST 1/
4" OF TRAVEL, TOP OR BOTTOM, IT SHOULD BE ADJUSTED.
2. Ignition/Emergency Stop.
An ON-OFF IGNITION/EMERGENCY STOP switch
and a separate START push button on the platform
console supply electrical power to the starter sole-
noid, when the ignition switch is pulled out to the
“IGNITION ON” position and the START button is
depressed.
3. Start Button.
The START button is a momentary contact, push-
button switch. With the IGNITION/EMERGENCY
STOP switch pulled up and the START button
depressed, electrical power is supplied to the start
solenoid.
4. Warning Horn.
A push-type HORN switch, when pressed, supplies
electrical power to activate the horn.
5. Tilt Alarm Warning Light.
This red indicator lights to indicate that the chassis
is on a slope (over 5 degrees). If illuminated when
boom is raised or extended, retract and lower to
below horizontal then reposition the machine so it is
level before extending boom or raising boom above
horizontal.
IF THE TILT ALARM IS ILLUMINATED WHEN BOOM IS RAISED OR
EXTENDED, RETRACT AND LOWER THE PLATFORM TO BELOW
HORIZONTAL THEN REPOSITION THE MACHINE SO IT IS LEVEL
BEFORE EXTENDING THE BOOM OR RAISING THE BOOM ABOVE
HORIZONTAL.
NOTE: LIFT, SWING, and DRIVE control levers or switches
are spring-loaded and will automatically return to the
neutral (OFF) position when released.
TO AVOID SERIOUS INJURY, DO NOT OPERATE THE MACHINE IF
ANY CONTROL LEVERS OR TOGGLE SWITCHES CONTROLLING
PLATFORM MOVEMENT DO NOT RETURN TO THE OFF OR NEU-
TRAL POSITION WHEN RELEASED.
6. Lift.
The LIFT controller provides raising and lowering of
the boom when positioned to UP or DOWN.
7. Telescope.
The TELESCOPE control switch provides extension
and retraction of the boom when positioned to IN or
OUT.
8. Steer/Axles.
On standard machines, positioning the STEER/
AXLES control switch right or left enables steering
the machine to the right or to the left.
On machines equipped with hydraulic extendable
axles, the function the switch controls is dependent
upon the position of the lever on the STEER/AXLES
SELECTOR valve.
NOTE: On machines equipped with four wheel steering, the
drive controller will have a thumb-rocker switch con-
trolling rear wheel steering.
9. Swing.
The SWING controller provides 360 degrees contin-
uous swing when positioned to LEFT or RIGHT.
