14. Jib Stow Override
This switch allows the operator to rotate the jib to the right
past the electronic stop to stow the jib under the boom for
transport.

CCW for slower speed and CW for faster speed. To adjust to
creep, turn knob fully CCW until it clicks.

ring below the handle.
NOTE: The MAIN LIFT/SWING control lever is spring-loaded and will

16. Main Lift/Swing Controller
An infinitely proportional dual axis joystick is provided for
main lift and swing. Push forward to lift up, pull backward to
lift down. Move right to swing right, move left to swing left.
NOTE: When boom is positioned above transport position or telescoped
out and any of the following switches, DRIVE SPEED/TORQUE
SELECT or FUNCTION SPEED, are positioned to HIGH, high func-
tion speeds are automatically cut out and the machine contin-
ues to operate at a lower speed.
DO NOT OPERATE MACHINE IF DRIVE SPEED /TORQUE SELECT OR FUNCTION SPEED
SWITCHES OPERATE WHEN BOOM IS MORE THAN 15° ABOVE HORIZONTAL.
17. Drive Speed/Torque Select
The forward position gives maximum drive speed by shifting
the drive motors to minimum displacement and giving high
engine when drive controller is moved. The back position
gives maximum torque for rough terrain and climbing
grades by shifting the wheel motors to maximum displace-
ment and giving high engine speed when drive controller is
moved. The center position allows the machine to be driven
as quietly as possible by leaving the engine at mid speed
and the drive motors in maximum displacement.
