Tightness inspection
Hoses check
Make sure that connecting hoses 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.
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.
Filtering chamber gasket check for machines
equipped with Longopac® system
Ensure that the Longopac® bag is tight with the gasket (2).
Also check the seal of the gasket positioned on the discharge
clapet (1).
The gasket must be replaced if it is torn, cut, etc...
