FRAME DUST FILTER CLEANING AND INTEGRITY CHECK

POCKET 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.

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).

WARNING!

When reinstalling the filter, the wire gauze (2, Fig. O) must be facing upward.

NOTE

If necessary, they can be cleaned using the procedure indicated below.

When the filtration surfaces are no longer suitable, the filter must be replaced.

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.Remove the filter cover (2, Fig. M) by disengaging it from the retainers (1).

5.Unscrew the knobs (1, Fig. AA) and remove the brackets (2).

6.Pull out the dust filter (1, Fig. AB), and remove it after disconnecting the electrical connector (2) from the filter shaker.

(6).

12.Remove the internal pocket separator (7, Fig. AC).

13.Clean the polyester fibre surface (8, Fig. AC) from the dirty side, using an external vacuum cleaner, 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.
