1 Unfasten the latches and remove the cover.
2 Press with both thumbs on primary filter (A) at the same time
as you pull it out. This is to prevent secondary filter (B) from
coming out together with the primary filter.
3 Carefully tap the end of the primary filter against a soft and
clean surface.

Do not tap against a hard object.
4 If using compressed air when cleaning, do not let the pressure
exceed 5bar (73 PSI). Do not hold the nozzle closer than 30–
50 mm (1.2–2.0 in).
5 Blow the filter from the inside along the folds.
6 Check the filter with the aid of a lamp, preferably in a dark
room. If there is the smallest hole, scratch, crack or other
damage, the filter must be replaced.
7 Empty and clean the cover before reinstalling.
