Cleaning the air filter
Notice
Ensure that the air filters are neither worn nor
damaged. The corners and edges of the air filters must
not be deformed or rounded. Before reinserting the air
filters, make sure that they are undamaged and dry!
The air filters have to be cleaned as soon as they are dirty. This

and faults).
