Check

1

Chock the front axle wheels

This avoid that the vehicles moves accidentally.

2

Check the lever of the automatic regulator

The lever of the regulator must move smoothly and without locking in any point of its travel.

3

Depressurize the compressed air system

4

Check the length of the valve lever

.Rod length (adjustment)

*BE42.80-B-1003-01I

5

Determine the load over the rear axle


The vehicle can only be lifted unloaded.
Otherwise, the rear axle housing can be damaged.


In vehicles with 2 rear axles, both rear axles must be lifted simultaneously.
Because the load over the rear axle is distributed among both rear axles.
