Tightness inspection
Hoses check
Figure 19
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 from the outside to remove deposits.
Cover tightness check
Figure 20
If the gasket (1) under the cover (4) has become slack, remove
the screws (2) that lock the closing hooks (3) in place and allow
them to slide downwards until the cover closes perfectly.
Replace the gasket if the tightness is still not optimal.
Filtering chamber gasket check for machines
equipped with dust container
Figure 21
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.
