competent maintenance staff before operation continues.
5.1 Maintenance intervals

maintenance intervals.

The recommended change cycles are based on empirical values for dosing applications.
The empirical values are based on different material properties, pressure conditions and
dosing settings. Depending on the material used, the required change cycles may differ from
the recommended cycles.
Ambient conditions, such as temperature and humidity, may affect the change cycles.

Maintenance and cleaning work may only be carried out when the machine has been shut
