Cleaning the air filter
Note
Ensure that the air filter is not worn or damaged. The
corners and edges of the air filter must not be
deformed or rounded. Before reinserting the air filter,
make sure that it is undamaged and dry!
The air filter has to be cleaned as soon as it is dirty. This is
brought to light e.g. by a reduced capacity (see chapter Errors
and faults).
1. Remove the air filter from the device.
