Axle Switches
Axle switch controls are listed here in alphabetical order.
Note: See General Information for detailed information about axle switch functions.
Differential Lock Switch
Fig. 1, Forward Drive Axle Differential Lock Switch
Fig. 2, Rear Drive Axle Differential Lock Switch
The differential lock switch, as shown in Fig. or Fig., provides maximum traction for slippery conditions by forcing the wheels on each drive axle governed by the switch to rotate together. Engagement can be at any speed, provided the wheels are not slipping or spinning.
Interaxle Lock Switch
The interaxle lock switch allows the driver to lock the drive axles together, causing the drive axle shafts to rotate together. See Fig.. Use this feature only under adverse road conditions where greater traction is needed.
Fig. 3, Interaxle Lock Switch
Leave the control in the UNLOCK position for normal highway operation. When a spinning or slipping action occurs at any of the drive wheels, press the upper half of the switch to LOCK the differential and prevent the wheels from spinning.
Notice: Do not shift into LOCK while the rear wheels are spinning. Come to a halt before engaging to prevent damage to the interaxle and main differentials.
Do not permit rear wheels to spin freely for more than ten seconds when traction is lost. Shift into LOCK to prevent damage to the interaxle and main differentials.
Lift Axle Switch
The lift axle switch controls the lift axle operation. See Fig.. Pushing the upper half of the switch will lower the lift axle.
