Operation

3. Crab Steering Mode
All wheels will steer in the same direction that the steering wheel is turned. This
steering mode allows the operator to move the vehicle ìsidewaysî toward the landing
point of a load. This is especially useful on a congested worksite in order to line up at
the exact spot in front of the loading location.
Four Wheel Steer Indexing
If the vehicle does not drive ìstraight,î the steering could be ìout of phase.î Perform
the following procedure to synchronize the front and rear steering.
1. Select the four wheel steer mode with the steer mode selector.
2. Turn the steering wheel all the way to the right until it reaches the stop.
3. Select the front wheel steer mode with the steer mode selector.
4. Turn the steering wheel to the left, about one complete revolution.
5. Select the four wheel steer mode with the steer mode selector.
6. Turn the steering wheel all the way to the right until it reaches the stop. This
will ensure the rear wheels are fully against the right stop.
7. Select the front wheel steer mode with the steer mode selector.
8. Turn the steering wheel all the way to the right until it reaches the stop.
9. Select the four wheel steer mode with the steer mode selector.
10. Turn the steering wheel to the left, until the wheels are pointing straight
ahead.
11. Drive the vehicle forward a short distance to check the wheel tracking.
