FRAME DUST FILTER CLEANING AND
INTEGRITY CHECK
1. Drive the machine on a level ground and engage the
parking brake by means of the pedal and the lever (26
and 19, Fig. B).
2. Turn the ignition switch (18, Fig. B) to “0” position.
3. Open the hood (13, Fig. C) and hold it by using the
related rod (16, Fig V).
4. Disconnect the battery connector (4, Fig. V).
Remove the filter cover (2, Fig. M) by disengaging it
from the retainers (1).
5. Disconnect the electric connector (1, Fig. N) from the
filter shaker.
6. Remove the filter shaker support frame fixing knobs
(2, Fig. N).
7. Remove the filter support frame (3, Fig. N).
8. Pull out the dust filter (4, Fig. N).
9. In an appropriate outdoor area, clean the filter
shaking it on a level and clean surface, tapping the
side (1, Fig. O), opposite the wire gauze (2).
Complete the cleaning by using compressed air (3) at
max. 6 bars, blowing only from the side protected by
the wire gauze (2), at a minimum distance of 30 cm.
According to the filter type, take care of the following
cautions:
– Paper filter (standard): do not use water or
detergents to clean it; the filter can be damaged;
– Polyester filter (optional): to clean it, see the
above-mentioned instructions. If necessary, for a
better cleaning, it is allowed to wash the filter with
water and non-lathering detergents. This provides
better quality cleaning but reduces the life of the
filter, which will have to be replaced more
frequently. The use of inadequate detergents can
damage the filter.
Check the filter body for lacerations.
10. Clean the filter compartment rubber seal (1, Fig. P)
along its perimeter and check its integrity. If
necessary, replace it.
11. Install in the reverse order of removal (steps from 8 to
1).

spreading it out completely or cleaning pocket by
pocket. At the same time, clean both the surfaces of
the pocket separator (7, Fig. AC) removing anything
deposited on them. Check that the filtering surface is
not cut, if it is, replace it. It is also possible to use
compressed air (max. 6 bars), blowing the air from
the clean side towards the dirty side.
NOTE
Besides the standard paper filter, optional
polyester filters are also available. The
following procedure is applicable to each
type.
WARNING!
When reinstalling the filter, the wire gauze

kept clean by activating the electric filter
shaker supplied with the machine.
If necessary, they can be cleaned using the
procedure indicated below.
When the filtration surfaces are no longer
suitable, the filter must be replaced.
WARNING!
It is not advisable to wash the filter with
water. The polyester fibre can shrink and
become unusable.
