RT765E-2 OPERATOR MANUAL
WARNING
Unexpected Operation Hazard!
Operate the rear steer ONLY at slow speeds for added job
site maneuverability.
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.
