Interval
After 10 operating hours
Retighten all screw and plug-in
connections as well as the hydraulic
connections.
Even firmly tightened screw connections can come loose
(e.g. because of material settlement or paint residues be-
tween the screw elements). This can lead to loose screw
connections and leaking hydraulic connections.

Depending on the conditions of use (e.g. weather influences) or in case
of higher strains on the machine the hoses may need to be replaced
earlier.
Have the hydraulic system checked by an expert at least once every
year.
In addition follow the country specific regulations and directives.
