RT765E-2 OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
Rear Wheel Steering
Rear wheel steering is controlled by the Rear Steer Control
Switch. Moving the control switch to the desired position
activates the rear steer cylinders, thereby steering the crane
in the selected direction.
Four Wheel Steering
Four wheel steering is accomplished with the steering wheel
and the Rear Steer Control Switch. Depending upon which
direction the operator wishes to travel, the steering wheel is
turned opposite direction of the Rear Steer control position.
This allows the crane to turn or maneuver in close, restricted
areas.
Crabbing
Crabbing is accomplished with the steering wheel and the
Rear Steer Control Switch. Depending upon which direction
the operator wishes to travel (crab), the steering wheel is
turned in the same direction as the Rear Steer Control
Switch. This permits driving the crane forward or backward in
a crabbing manner.
Four-Wheel Drive Operation
If more traction is required due to slipping or spinning
wheels, engage the front axle drive as follows:
1. Stop the crane by depressing the Service Brake Foot
Pedal.
2. Position the Transmission Shift Lever to the neutral (N)
position.
3. Position the Drive Axle Selector Switch to four-wheel
low.
NOTE: If the Drive Axle Selector Switch is positioned to
four-wheel low and the Service Brake Foot Pedal is
not depressed and the Transmission Shift Lever is
not in neutral (N) position, the Four-Wheel Drive
Indicator will flash and the four-wheel drive function
will not engage.
WARNING
Unexpected Operation Hazard!
Operate the rear steer ONLY at slow speeds for added job
site maneuverability.
CAUTION
Machine Damage Hazard!
Do not tow or pull in 1st gear with the Drive Axle Selector
Switch in two-wheel drive position. Severe damage to the
drive train will result. Always engage four-wheel drive.
CAUTION
Possible Machine Damage!
Before shifting from two-wheel drive to four-wheel drive
(or from four back to two), crane travel must be stopped.
