FRAME DUST FILTER CLEANING AND
INTEGRITY CHECK
1. Drive the machine on a level ground and activate the
parking brake using the pedal and the lever (22 and
15, Fig. B).
2. Turn the ignition key (14, Fig. B) to “0” position.
3. Open the hood (13, Fig. C).
4. Remove the dust 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 handwheels
(2, Fig. N).
7. Remove the filter-shaker support frame (3, Fig. N).
8. Pull out the dust filter (4, Fig. N) upwards.
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 means of 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 (see figure O).
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. 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 unsuitable
detergents can damage the filter. Check the
filter body for tears.
10. If necessary 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).
