General Information
To prevent injury, make sure that no maintenance work is being performed on the machine or near the machine. Keep the machine under control at all times in order to prevent injury.
Reduce the engine speed when you maneuver the machine in tight quarters or when you break over a rise.
Select the gear range that is necessary before you start the downgrade. Do not change gears when you are going downhill. As required, use the service brake pedal in order to control the vehicle speed and the engine speed.
When you drive down a grade, use the same gear range that is used for driving up a grade.
Changing Direction and Gear
NOTICE |
---|
For operator comfort and maximum service life of power train components, deceleration and/or braking is recommended before any directional shifts are made. |
Gear changes and directional changes at full engine speed are possible. However, deceleration and/or braking is recommended when you change direction. This will maximize operator comfort and the service life of transmission components.
- Push the decelerator pedal downward in order to decrease the engine speed.
- Rotate the directional control to the desired direction.

- Push the upshift to the desired gear, or push the downshift to the desired gear.
- Increase the engine speed by releasing the decelerator pedal.
Normal Steering
Illustration 2 | g00038323 |
Pull the right steering clutch/brake lever toward the detent in order to make a gradual right turn.
Pull the steering clutch/brake lever against the stop in order to make a sharp right turn. This applies the right brake.

Pull the left steering clutch until you feel slight pressure. This will release the left steering clutch in order to make a gradual left turn.
Pull the steering clutch/brake lever against the stop in order to make a sharp left turn. This applies the left brake.
Note: When the machine is under load, use the bulldozer blade tilt lever in order to aid steering. This technique allows equal power to be maintained by both tracks against the load.
Steering on a Steep Downgrade
Illustration 4 | g00038414 |
"Cross-steering" is a gradual turn that is made on a steep downgrade. The turn is accomplished by declutching without braking.
To make a gradual right turn, pull back the left steering clutch/brake lever (1) (cross steering) to the detent. This releases the left steering clutch.
To make a sharp right turn, pull back the right lever (2) against the stop. This applies the right brake (normal steering).
To make a gradual left turn, pull back the right steering clutch/brake lever (2) (cross steering) to the detent. This releases the right steering clutch.
To make a sharp left turn, pull back the left lever (1) against the stop. This applies the left brake (normal steering).
To make a long gradual turn, you should make a correction that is short in duration. This is especially true for roading the machine. This method improves brake life.
