DUST FILTER CLEANING AND INTEGRITY
CHECK
NOTE
Besides the standard paper filter, optional
polyester filters are also available. The
following procedure is applicable to each type
of filter.
1. Drive the machine on a level ground and activate the
pedal brake (26, Fig. C) (if present).
2. Turn the ignition key (2, Fig. B) to "0" position.
3. Disengage the retainer (18, Fig. C).
4. By means of the handle (19, Fig. C) pull out the
hopper (17).
5. Turn the handle (1, Fig. L) upwards (90°
approximately) and let the filter frame (2) rotate
outwards.
6. Pull out the dust filter (3) upwards.
7. In an outdoor area, clean the filter shaking it on a level
and clean surface, tapping the side (1, Fig. M),
opposite to the wire gauze (2). Complete the cleaning
by means of a compressed air perpendicular jet (3) of
max. 6 bars, blowing only from the side protected by
the wire gauze (2).
According to the filter type, observe 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. 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 unsuitable detergents can damage the
filter.
8. Check the filter body for tears.
9. If necessary, clean the filter compartment rubber seal
(4, Fig. L) along its perimeter and check it for integrity.
If necessary, replace it.
10. Reassemble in the reverse order of disassembly.
NOTE
Reinstall the filter with the wire gauze (2, Fig.
M) facing the front part of the machine. (Facing
the fan (16, Fig. U)).
