C AU T I O N
Do not engage the differential lock control at high speeds.
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.
Failure to follow these cautions will result in damage to machine.
N OT E
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.
Differential lock can be engaged while machine is in motion.
Anticipate need for use of differential lock before wheel slippage occurs.
1. Engage differential lock by pushing switch on right joystick to increase traction on soft or wet ground (Figure 8).
Differential lock indicator will illuminate on monitoring system when differential locks.
2. Continue grading.
3. Disengage differential lock by pushing switch on right joystick again.
