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.

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.

Illustration 1 g00038596 - 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.

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.

“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.
The purpose of the Oil Renewal System (ORS) is intended to increase the oil change interval. The purpose of the Oil Renewal System (ORS) is also intended to decrease the amount of used oil in need of disposal. The life of the engine is not shortened when this is accomplished.
Reference: For more information on the Oil Renewal System, refer to Systems Operation, RENR8160, "Oil Renewal System".

When the machine is equipped with the Oil Renewal System (ORS), the engine oil level must be checked daily and replenished as needed. Otherwise reduced engine life will result. |
The ORS meters engine oil that has been filtered into the fuel supply of the machine. This oil will be consumed in the engine during the normal process of combustion. The amount of oil that is metered is calculated by the Engine Control Module (ECM). This amount is based on the actual load factor or the fuel that is consumed by the engine.
New oil is added to the makeup oil tank on a regular basis in order to replenish the oil that is consumed . Regular additions of new oil will allow the life of the oil to be extended. Reviewing the reports of the Scheduled Oil Sampling (S·O·S) Oil Analysis will determine if a problem has occurred and if the oil needs to be changed.
The ORS is integrated with the engine and the electronic system of the machine. The electronic system consists of a sensor, a metering valve, the Engine Control Module (ECM), and the Vital Information Management System (VIMS).
The sensor is located in the makeup oil tank. The sensor monitors the oil level in the makeup oil tank. The makeup oil tank is located on the left side of the machine near the cab. The makeup oil tank supplies oil to the engine.
The metering valve is located on the left rear side of the engine. The metering valve is controlled by the Engine Control Module (ECM).
The electronic system will notify the operator of a system malfunction or warning. The following warnings are detected:
- Fault of the metering valve
- Plugging of the engine oil filter
- Low makeup oil level
- Low engine oil pressure
The electronics of the engine will automatically turn off the oil renewal system in order to avoid possible damage to the engine. The system can be restarted by correcting the problem and cycling the power.
The benefits of the ORS include the following items:
- A reduction or elimination in the number of oil changes
- A reduction or elimination of the disposal of used engine oil
- An increase in the availability of the machine
