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.
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 at all times by eliminating wheel spin. Any excessive uncontrolled wheel spin can cause accelerated wear on certain components of the drive train. This is due to inadequate lubrication while the wheel is spinning.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.
