Brake test
Information
Do not put the machine into operation if a brake test gives a negative
result or if there are doubts as to the correct brake function.
Contact a Wacker Neuson service center and have the malfunction
rectified.
The following tests help check the brake function. If possible, always park
the machine without any load and on level ground, and secure it with
suitable means (for example chocks).
Perform the brake tests once a day on firm, level and horizontal ground.
First perform the test for the parking brake, then the one for the service
brake.
