8. Maintenance
8.1 Warranty
We cannot accept liability for damages resulting from failure to observe the installation and operating instructions.
Please note that repairs to compressor/vacuum pumps must be carried out only by authorised repair shops using original
replacement parts; otherwise, the warranty becomes invalid. You will find a list of our service centres on the back page of the
manual.
8.2 Maintenance Plan
Safety regulations ( section 2 ) must be observed during maintenance and inspection procedures.
Operating failures due to insufficient or incorrect maintenance can cause extremely high repair costs and machine downtime;
therefore, regular maintenance is imperative.
Operational safety and the service life of the machine depend largely on correct maintenance.
The table below contains information concerning scheduling, monitoring and type of maintenance tasks necessary under normal
use of the compressor/vacuum pump.

The indicated maintenance intervals are based on an operating period of approximately five hours per day. Intervals can be
extended accordingly in case of shorter operating periods.
After work is completed, all protective devices must be refitted.
When disposing oil, grease, cleaning solvents or components (e.g. shaft seals) the environmental regulations
must be observed.
Due to differing operating circumstances, one cannot predict how often checks for wear, maintenance and inspections will be
necessary. We advise you to draw up a plan after consideration of your operating circumstances.
