RT600E OPERATOR MANUAL
Traveling — Forward
CAUTION
Machine Damage Hazard!
Engage the turntable lock pin for extended travel. Failure
to engage the lock pin may allow the superstructure to
swing uncontrolled, damaging the machine and/or
property.
1. With the Transmission Shift Lever in the neutral (N)
position.
2. Depress the Service Brake Foot Pedal.
NOTE: The engine will not crank unless the transmission
shift lever is in neutral and the service brake foot
pedal is depressed.
3. Start the engine and allow it to adequately warm up.
4. Position the Drive Axle Switch to either two-wheel high
or four-wheel low.
CAUTION
Use four-wheel drive only when more traction is required.
NOTE: If service brake hydraulic accumulator pressure is
low, the parking brake cannot be released.
5. Lift the Transmission Shift Lever up out of its detent and
push the lever to the forward (F) position, then rotate the
Transmission Shift Lever Knob to the first (1) gear
position. The gear selection "F1" will appear in the LCD
Display to indicate that forward propulsion and first (1)
gear have been selected; if the Service Brake Foot
Pedal is not depressed prior to shifting to a gear, the
gear selection will flash in the LCD Display until the
Transmission Shift Lever is returned to the neutral (N)
position and the transmission will not shift.
6. Release the Service Brake Foot Pedal and depress the
Foot Throttle Pedal until maximum first gear speed is
attained, then rotate the Transmission Shift Lever Knob
to the second (2) gear position to continue to increase
speed. For additional speed, continue shifting to a
higher gear.
CAUTION
Possible Machine Damage!
Do not downshift to a lower gear if the road speed is
greater than the maximum speed of the lower gear.

OPERATING CONTROLS AND PROCEDURES
Traveling — Reverse
Traveling in reverse is accomplished the same way as
traveling forward, except for shifting the Transmission Shift
Lever to reverse (R). Refer to Traveling — Forward, page 3-
25.
Apply service brakes and bring crane to a complete stop
before shifting transmission into reverse.
Steering
Steering is accomplished by the steering wheel and the rear
steer control. These controls, used singly or together,
provide front wheel steering, rear wheel steering, four-wheel
steering, and crabbing capabilities Figure 3-5.
Front Wheel Steering
Conventional front wheel steering is accomplished with the
steering wheel. This method of steering should always be
used when traveling at higher speeds.
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.
