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 MACHINE SO THAT IT IS LEVEL
BEFORE EXTENDING BOOM OR RAISING BOOM ABOVE HORI-
ZONTAL.
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 or 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.
9. Swing.
The SWING controller provides 360 degrees contin-
uous swing when positioned to LEFT or RIGHT.
NOTE: When the boom is above horizontal and if either the
ENGINE SPEED, PUMP VOLUME, or WHEEL
MOTOR SPEED are positioned to HIGH, high speed
functions are automatically cut out and the machine
continues to operate at a lower speed.
DO NOT OPERATE MACHINE IF HIGH ENGINE SPEED, HIGH
WHEEL MOTOR SPEED, OR HIGH PUMP VOLUME OPERATE
WHEN BOOM IS ABOVE HORIZONTAL.
10. Engine Speed.
The two position ENGINE SPEED control switch
allows the operator to select higher function speeds
or higher drive speed when positioned to HIGH.
11. Wheel Motor Speed.
The two position WHEEL MOTOR SPEED control
switch allows the operator to select high wheel
motor speed when positioned to HIGH. When used
in conjunction with HIGH ENGINE speed, it gives
the machine a faster drive speed.
