Differential Lock Control (29)
| NOTICE |
|---|
To prevent damage to the differential, do not engage the differential lock control at running conditions. Do not turn machine with differential lock engaged. Do not engage the differential lock control while one wheel is spinning. Decrease engine rpm until the wheel stops spinning. Anticipate using the differential lock before wheel slippage occurs. In areas of high resistance, it may be necessary to turn the machine slightly in order to aid in unlocking the differential lock. Decreasing the engine rpm may also be helpful. |
| LOCKED - Push the floor switch in order to lock the differential. When the differential is locked, an indicator light will illuminate on the front dash. The differential lock will help to prevent wheel slippage. Use the differential lock when you grade on soft ground or on wet ground. Engage the differential lock only when the wheels are not slipping. |
| UNLOCKED - Release the floor switch in order to unlock the differential. |
Lock the differential in order to increase the traction, as required.
Make sure that the differential is unlocked when you turn the machine or when you articulate the machine. Also, make sure that the differential is unlocked when you are roading the machine.
| NOTICE |
|---|
Use of the differential lock when turning, articulating or roading may cause drive train component damage. |
When one of the tandem wheels encounters loose surfaces or slippery surfaces, the differential lock will provide maximum traction. Wheel spin is minimized. Any excessive uncontrolled wheel spin can cause accelerated wear on certain components of the drive train. There is inadequate lubrication while the wheel is spinning.
Do not engage differential lock control while one wheel is spinning. Decrease engine rpm until the wheel stops spinning. Anticipate using the differential lock before wheel slippage occurs.

Operator Information
To prevent injury, make sure that no people are working on the machine or near the machine. To prevent injury, keep the machine under control at all times.
Reduce engine speed when you maneuver in tight quarters or when you are going over a hill.
Select the necessary travel speed before you start downgrade. Do not change travel speed while you are going downhill.
When you go downgrade, use the same speed to go upgrade.
Do not allow the engine to overspeed when you go downhill. Use the service brake to reduce engine overspeed when you go downhill.
When the load will be pushing the machine, put the speed control in SLOW speed before you start downhill.
- Adjust the operator seat.
- Fasten the seat belt.
- Raise the work tools in order to negotiate any obstacles.
- Push down on the service brake in order to prevent the machine from moving.
- Release the parking brake.
- Push the direction control switch for the desired direction.
- Release the service brake.
- Push down on the accelerator pedal until you achieve the desired engine speed.
- Drive the machine forward for the best visibility and for the best control.
Note: For operator comfort, stop the machine before any directional shifts are made. For maximum life of the power train components, stop the machine before any directional shifts are made.
