8 Performing Maintenance

For a long, trouble-free service life of the product, regular
maintenance activities are required.

This chapter contains the description of the required mainte-
nance activities and the qualifications of the staff needed to
carry out these tasks.

WARNING

The hydraulic system is under operating pressure

Danger of bodily injury

The hydraulic system must be depressurized before
performing any work on it.

Depending on the model of the filter unit, the changing of the
filter element is different, too.
