SECTION 3 - USER RESPONSIBILITIES AND MACHINE CONTROL
3120270 – JLG Lift – 3-29
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, DRIVE SPEED, 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 THE MACHINE IF HIGH ENGINE SPEED, HIGH
WHEEL MOTOR SPEED, OR HIGH DRIVE SPEED OPERATE WHEN
THE BOOM IS ABOVE HORIZONTAL.
10. Engine Speed.
The two position HIGH 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.
TO AVOID PERSONNEL INJURY OR MACHINE DAMAGE, USE
SLOW FUNCTION SPEED CONTROL WHEN POSITIONING THE
PLATFORM IN CLOSE QUARTERS.
12. Drive Speed.
The two-position DRIVE SPEED control switch
allows the operator to select high pump flow, pro-
viding additional speed to the drive function when
positioned to HIGH.
13. Engine Running Light.
This indicator lights to notify the operator that the
engine is running.
14. Wheel Drive.
The WHEEL 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.
