Primary filter replacement for machines that handle
dusts that are hazardous to health.
Figure 13
To replace the primary filter safely, follow the instructions
according to the type of filter/cleaning system installed on the
machine, and proceed as follows:
■
Insert the plug (1) in the vacuum inlet.
■
Insert the belt (2) around the filter chamber.
■
Place the bag with the elastic band on the filter chamber
(3). Tighten the safety belt (4) on the bag, above the band.
■
Tuck in the bag along its length. (5)
■
Remove the star filter (6) by grasping the ring with the
gasket and lift it until it is completely out of the filter
chamber (7).
■
Turn the bag on itself to obtain a section of coiled bags to
be tightened with two clamps (8). Place the two clamps at
a distance of 50 mm between them, then cut in-between
(9) as shown in the figure.
■
Dispose of the filter (10) according to the laws in force.
■
Loosen the belt (11) and carefully move the bag elastic
band (12) towards the filter chamber upper edge.
■
Insert the second bag (13) over the first bag (14) and
tighten the safety belt (15) on the new bag.
■
Through the new bag (13) carefully remove the crop of the
first bag (14) from the edge of the filter chamber.
■
Bring the crop (14) towards the end of the second bag
(13).
■
Turn the bag (13) on itself to obtain a section of coiled
bags and close of the crop (14) at the bottom of the bag
(13) by tightening the clamp (16)
■
Loosen and remove the belt and gently remove the bag
from the edge of the filter chamber.

■
Unlock the safety bolt (3).
■
Use lever (2) to release vacuum unit (1) then pull it up and
out of the vacuum cleaner.
■
Unscrew the ring nut (4).
■
Pull out disc (5) and absolute filter (6).
■
Place absolute filter (6) in a plastic bag, close the bag
hermetically and dispose of the filter in accordance with
the laws in force.
■
Insert a new filter (6) with the same filtering characteristics
as the removed one.
■
Lock the absolute filter with the disc (5) and tighten the
ring nut (4).
■
Replace vacuum unit (1).
■
Fix the vacuum unit in place with lever (2) and lock safety
bolt (3) again.
Installation, cleaning and replacement of
the separator (optional)
Instructions describing how to fit the optional kits and the
relative operation and maintenance manuals are supplied
together with the optional kits.
If there is only a dust deposit on the separator (4) allow the
dust to drop through the central hole.
The separator (4) should first be disassembled in order to be
perfectly cleaned:
■
Release the closing hooks (1) of the cover (2) and remove
the cover.
■
Remove the filter.
■
Unscrew the two screws (3) and remove it from the
container.
■
Replace the part if it is excessively worn.
■
Reinstall the separator (4).
■
Lock it and fix it by means of the two screws (3).
■
Fit the filter back in place, close the cover (2) and lock it by
means of the two the closing hooks (1).
Tightness inspection
Hoses check
Make sure that connecting hoses (1) are in a good condition
and correctly fixed.
If the hoses are damaged, broken or badly connected to the
unions, they must be replaced.
When sticky materials are treated, check for possible clogging
along the hose, in the inlet and on the baffle plate inside the
filtering chamber.
To clean, scrape the inlet (2) from the outside to remove
deposits.
Filtering chamber gasket check for machines
equipped with dust container
If the gasket (1) between the container and the filtering chamber
(3) fails to guarantee sealing:
■
Loosen the four screws (2) that lock the filtering chamber
(3) against the machine structure.
■
Allow the filtering chamber (3) to lower down and tighten
the screws (2) once it has reached the sealing position.
If an optimal seal is not yet obtained or if there are tears, cracks,
etc., the gasket must be replaced.
