Risk of accidents due to incorrect work on the vehicle brakes.
Incorrect work on the vehicle brakes can lead to failure of the brakes caus-
ing severe accidents.
Incorrect work invalidates the operating licence of the truck crane and no

All repair work on the vehicle brakes may only be performed by

or an authorised GROVE dealer or an authorised spe-
cialist workshop with specially trained repair crew.
