Tightness inspection

1.
Blower connecting hose
2. Vacuum hose
Hoses check
Make sure that connecting hose (1) is in a good condition and
correctly fixed.
If the hose is damaged, broken or badly connected to the
unions, it must be replaced.
When sticky materials are treated, check for possible clogging
along the hose (2), in the inlet and on the baffle plate inside
the filtering chamber.
Scrape the inlet from the outside and remove the deposited
waste as indicated in the figure.
1. Seal
2. Screws
3. Filtering chamber
Filtering chamber tightness check
If the gasket (1) between the container and the filtering
chamber (3) fails to guarantee tightness:
■ Loosen the four screws (2) that lock the filtering chamber
(3) against the vacuum cleaner structure.
■ Allow the filtering chamber (3) to lower down and tighten
the screws (2) once it has reached the tightness position.
The gasket (1) must be replaced if it is torn, cut, etc... Replace
the gasket (1) if the degree of tightness is still not optimum.
