Frame Pocket Dust Filter Cleaning And Integrity Check; Skirt Height And Operation Check - Nilfisk Advance Terra 3700B Mode D'emploi Et D'entretien

FRAME POCKET DUST FILTER CLEANING
AND INTEGRITY CHECK
NOTE
Besides the standard paper filter, polyester
filters are also available. The following
procedure is applicable to each type of filter.
1. Drive the machine on a level ground and engage the
parking brake (6 and 7, Fig. C).
2. Turn the ignition switch (2, Fig. B) to "0" position.
3. Remove the hopper hook (21, Fig. C).
4. Remove the hopper (20) by using the handle (22, Fig.
C).
5. Turn the handle (1, Fig. L) downwards (90 degree
approximately) and let the filter frame (2) rotate
outwards.
6. Pull out the dust filter (3) upwards.
7. In an appropriate outdoor area, clean the filter
shaking it on a level and clean surface, tapping the
side (1, Fig. M) 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, observe the following
cautions:
– Paper filter (standard): Do not use water or
detergents to clean it not to irreparably damage
the filter.
– 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.
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
Reassemble the filter with the wire gauze (2,
Fig. M) facing the fan (16, Fig. U).

Side skirt check
1. Check the side skirts (16 and 17, Fig. C) for integrity.
Replace the skirts when they have cuts (1, Fig. N)
larger than 0.79 in (20 mm) or cracks (2) larger than
0.39 in (10 mm) (for skirt replacement, refer to the
Service Manual).
2. Check that the side skirt (16 and 17, Fig. C) height
from the ground is within 0 and 0.12 in (0 and 3 mm)
(Fig. O). If necessary, adjust the skirt height,
proceeding as follows:
Left skirt:
– Raise the machine hood (10, Fig. C) and engage
the hood support rod (3, Fig. U).
– Loosen the knob (3, Fig. E) and remove the broom
left door (1, Fig. F), pulling it upwards to
disengage the retainers (2).

Right skirt:
– Remove the main broom, as described in the
related paragraph.
– Remove the belt (14, Fig. U) from the pulley (15);
to facilitate the operation, make the pulley (15)
rotate operating on the fan (16).

using its slots (2).
