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 cover of the air inlet.
2. Remove the filter from the cover.

3. Clean the filter using a slightly damp, soft, lint-free cloth. If
the filter is heavily contaminated, clean it with warm water
mixed with a neutral cleaning agent.
4. Allow the filter to dry completely. Do not insert a wet filter
into the device!
5. Reinsert the air filter into the cover.
6. Insert the air inlet cover into the device.
