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 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. Pump Volume.
The two-position PUMP VOLUME control switch
allows the operator to select high pump flow, pro-
viding additional speed to all functions when posi-
tioned to HIGH. When used in conjunction with high
ENGINE SPEED and WHEEL MOTOR SPEED
switches, it gives the machine a faster drive speed
range.
13. Drive.
The DRIVE controller provides driving either forward
or backward when positioned to FORWARD or
REVERSE. The controller is ramped to allow infi-
nitely variable driving speed between fast and slow.
14. 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 to UP or DOWN.
15. Platform Rotate (If Equipped).
The PLATFORM ROTATE control switch allows
operator to rotate the basket to the left or right when
positioned to the desired direction.
16. Extend-A-Reach (If Equipped).
The EXTEND-A-REACH control switch allows oper-
ator to raise or lower the extend-a-reach, as
required.
17. Choke (If Equipped).
A push-button switch supplies power to the choke
solenoid for cold weather starting.
18. Glo-Plug (If Equipped).
This push-button switch when depressed supplies
power to the diesel engine glow plugs for cold
weather start. See diesel engine operator manual
for instructions.
19. Lights Switch (If equipped).
The LIGHTS switch allows the operator to turn the
installed light options (except beacon light) on or
off.
