627G Wheel Tractor-Scraper Caterpillar


Differential Lock Control

Usage:

627G AXF


NOTICE

To prevent damage to the differential, 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.

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 Control - The differential lock control is on the floor of the operator compartment. There are two differential lock controls in the operator compartment. One of the controls is located to the left of the foot pedals and the other control is located on the right side of the foot pedals. Both of the differential lock controls will perform the same function. The differential lock control on the right is used when the operator seat is rotated to the right.

Lock - Push down the switch and hold down the switch in order to lock the differential. When the differential lock control is active, an indicator light will illuminate on the front dash. The differential lock will help to prevent wheel slippage. Use the differential lock when you are loading on soft ground or on wet ground. Engage the differential lock only when the wheels are not spinning.

Unlock - Release the switch in order to unlock the differential.
