7 Maintenance
7.1 General information
All service work must be carried out within the given deadlines and with the corresponding
care.
The life and production quality of the Airfilter can be maintained through precautionary service
of the components.
Besides the regular cleaning you are urgently advised to replace parts subject to wear and
tear as a precautionary measure.

The acoustic alarm will sound once again every time the Airfilter is switched on.
So that you are regularly reminded that the combifilter needs to be replaced in permanent
