Closed Pocket Filter Cleaning And Integrity Check; Skirt Height And Operation Check - Nilfisk Advance SR 1500H B Manuel D'emploi Et D'entretien

CLOSED POCKET FILTER CLEANING AND
INTEGRITY CHECK
NOTE
The polyester closed pocket filters are
normally 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.
1. Drive the machine on a level ground and activate the
parking brake using the pedal and the lever (9 and 10,
Fig. B).
2. Turn the ignition switch (5, Fig. B) to OFF position.
3. Remove the front cowling (11, Fig. C) after having
released the side retainers (12) and interior hooks
(13).
4. Release the retainers (1, Fig. K) and lift the cover (2)
using the handgrips (3).
5. Unscrew the knobs (1, Fig. L) and remove the
brackets (2).
6. Pull out the dust filter (1, Fig. M), and remove it after
disconnecting the electrical connector (2) from the
filter-shaker.
7. Disassemble the polyester filtering surface, as
indicated by the following steps; these procedures
must be carried out in a suitable outdoor area and the
Operator must be suitably equipped (gloves, mask,
glasses).
8. Remove the filter-shaker motor (1, Fig. N) by
unscrewing the two relevant fixing screws.
9. Open the filter-shaker motor support unit (2, Fig. N)
completely, by releasing the tension rods (3) for the
filtering pockets.
10. Remove all the filtering pocket tension rods (4, Fig.
N).
11. Open the upper retaining cord (5, Fig. N) of the closed
pocket filter to remove it from the upper frame (6).
12. Remove the internal pocket separator (7, Fig. N).
13. Proceed to clean the polyester fiber surface (8, Fig.
N) 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. N) removing
anything deposited on them. Check that the filtering
surface is not cut and, 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.
WARNING!
It is not advisable to wash the filter with
water. The polyester fibre can shrink and
become unusable.
14. If necessary, clean the filter compartment rubber seal
(3 and 4, Fig. M).
15. Reassemble all the components in the reverse order
of disassembly.
