Checking

Only carry out test when vehicle is unloaded and ready to drive.
Semitrailer/tractor combination without semitrailer, but with fifth wheel coupling

1

Compare the number of the brake valve with the specifications on the plate of the automatic load-dependent brake pressure control (ALB plate) in the vehicle

The setting of the automatic load-sensitive proportioning valve (ALB) is checked according to the bellows pressure.
