Mechanical cleaning
1 Open the left side door of the machine.
2 Pull finger (E) and turn cover (B)
counterclockwise to open it.
3 Press with both thumbs on primary filter (C) at
the same time as you pull it out. This is to prevent
the secondary filter (D) from coming out together
with the primary filter.
4 Carefully tap the end of the primary filter against
a soft and clean surface.
5 Install the primary filter and the cover.
NOTE!
Do not tap against a hard object.
Cleaning with compressed air
1 Use clean and dry compressed air with a max.
pressure of 500 kPa (5 bar) (73 psi). Do not hold
the nozzle closer than 3 ~ 5 cm (1 ~ 2 in).
2 Blow the filter from the inside along the folds.
3 Check the filter with the aid of a lamp.
4 If there is the smallest hole, scratch, crack or
other damage, the filter must be discarded.
5 Install the primary filter and the cover.
NOTE!
To discover the damage more easily, this check
should be made in a darkened room.
