GRT9165 OPERATOR MANUAL OPERATING PROCEDURES
4
Rear Wheel Steering
Rear wheel (tandem axle) steering is controlled by the Rear
Steer Switch. Pushing the left or right side of the switch
activates the rear steer cylinders, steering crane in the
selected direction.
Six-Wheel Steering
Six-wheel steering is accomplished with the steering wheel
and Rear Steer Switch.
To perform six-wheel steering with the boom centered over
the front (single axle) of the crane, the operator turns the
steering wheel in the same
direction as the Rear Steer
Switch.
Before driving the crane with the boom centered over the
rear tandem axle, operator must first reverse the driving
controls using the Steering Reversal Switch. When driving
controls are reversed, six-wheel steering is accomplished by
turning the steering wheel in the same
direction as the Rear
Steer Switch.
This allows crane to turn or maneuver in close, restricted
areas.
Crab Steering
Crab steering is accomplished with the steering wheel and
Rear Steer Switch.
To perform crab steering with the boom centered over the
front (single axle) of the crane, the operator turns the
steering wheel in the opposite
direction as the Rear Steer
Switch.
Before driving the crane with the boom centered over the
rear tandem axle, operator must first reverse the driving
controls using the Steering Reversal Switch. When driving
controls are reversed, crab steering is accomplished by
turning the steering wheel in the opposite
direction as the
Rear Steer Switch.
This permits driving crane forward or backward in a crab-like
manner.
Four-Wheel Drive Operation
If more traction is required due to slipping or spinning
wheels, engage the rear axle drive as follows:
1. Stop crane by pressing Service Brake Foot Pedal.
2. Position Transmission Shift Lever to neutral (N) position.
3. Position Drive Axle Selector Switch to four-wheel drive.
NOTE: If Drive Axle Selector Switch is positioned to
four-wheel drive, Service Brake Foot Pedal is not
pressed, and Transmission Shift Lever is not in
neutral (N) position Four-Wheel Drive Indicator will
flash and four-wheel drive function will not engage.
4. Select gear speed and direction of travel with Transmission
Shift Lever and Knob.
5. Drive crane following Traveling — Forward, page 4-17.
6. Return Drive Axle Selector Switch to two-wheel drive
position as soon as two-wheel traction will suffice and
crane motion has stopped. Service Brake Foot Pedal
must be pressed and Transmission Shift Lever must be
in Neutral (N) position to shift from four-wheel drive to
two-wheel drive.
Differential Lock Operation
NOTE: Differential lock will not operate unless Drive
Selector Switch is in four-wheel drive position.
WARNING
Rollover Hazard!
Operate rear steer ONLY at slow speeds. Operation of
rear steer at high speed may result in loss of steering
control and/or rollover of the crane. Death or serious
injury could occur.
CAUTION
Machine Damage Hazard!
Do not tow or pull in 1st gear with Drive Axle Selector
Switch in two-wheel drive position. Severe damage to
drivetrain 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.
CAUTION
Unexpected Operation!
When using differential lock, steering characteristics may
be affected.
Try to use four-wheel drive to gain adequate traction
before using differential lock.
Do not operate differential lock when traveling downhill; at
speeds above 16.1 km/h (10 mph); on hard, dry surfaces;
and/or during axle spin-out.
