IF THE CHASSIS OUT OF LEVEL WARNING LIGHT IS ILLUMI-
NATED WHEN THE BOOM IS RAISED OR EXTENDED, RETRACT
AND LOWER THE PLATFORM TO BELOW HORIZONTAL THEN
REPOSITION THE MACHINE SO IT IS LEVEL BEFORE EXTENDING
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
THE PLATFORM MOVEMENT DO NOT RETURN TO THE OFF OR
NEUTRAL POSITION WHEN RELEASED.
6.
Lift.
The LIFT control lever provides raising and lowering
of the boom when positioned to UP or DOWN and
automatically returns to off when released.
7.
Telescope.
The TELE control lever provides extension and
retraction or the boom when positioned to IN or
OUT, and automatically returns to off when released.
8.
Steer/Axles.
When in the steering mode, positioning the STEER/
AXLES control switch right or left enables steering
the machine to the right or to the left. When in the
axles mode, positioning the switch to EXTEND to
extend the axles and RETRACT to retract the axles.
The function the switch controls is dependent upon
the position of the STEER/AXLES selector valve.
9.
Swing.
The SWING control lever provides 360 degrees con-
tinuous swing when positioned to left or right.
NOTE: When the boom is above horizontal and if either the
HIGH ENGINE, PUMP VOLUME, or WHEEL
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.
High Engine.
The two position HIGH ENGINE control switch
allows the operator to select higher function speeds
or higher drive speed when in the high position.
11.
Wheel Motor Speed.
The two position WHEEL MOTOR SPEED control
switch allows the operator to select high wheel
motor speed when in the high position. When used
in conjunction with HIGH ENGINE speed, it gives the
machine a faster drive speed.
TO AVOID PERSONNEL INJURY OR MACHINE DAMAGE, USE
SLOW FUNCTION SPEED CONTROL WHEN POSITIONING THE
PLATFORM IN CLOSE QUARTERS.
12.
Pump Volume.
The two-position PUMP VOLUME control switch
allows the operator to select high pump flow, provid-
ing additional speed to all functions when in the high
position. When used in conjunction with HIGH
ENGINE and WHEEL MOTOR SPEED switches, it
gives the machine a faster drive speed range.
13.
Creep.
The CREEP control switch allows the operator to
select a lower speed for DRIVE, LIFT, SWING and
TELESCOPE, when in the on position.
14.
Drive.
The DRIVE controller provides driving either forward
or backward when positioned to forward or reverse.
The controller is ramped to allow infinitely variable
driving speed between fast and slow.
15.
Platform Level.
The PLATFORM LEVEL control switch allows the
operator to compensate for any difference in the
automatic self-leveling system by positioning the
switch up or down.
16.
Platform Rotate.
The platform ROTATE control switch allows operator
to rotate the basket to the left or right when posi-
tioned to the desired direction.
17.
Extend-A-Reach (If Equipped).
The EXTEND-A-REACH LIFT control switch allows
operator to raise or lower the extend-a-reach, as
required.
