Tightness inspection

Hoses check

Make sure that connecting hoses (1 and 2) are in a good
condition and correctly fixed.
If the hoses are damaged, broken or badly connected to the
unions (3), they must be replaced.
When sticky materials are treated, check for possible clogging
along the hose (2), in the inlet (4) and on the baffle plate
inside the filtering chamber.
Scrape the inlet (4) from the outside and remove the
deposited waste as indicated in the figure.
Filtering chamber tightness check
If the gasket (5) between the container (4) and the filtering
chamber (3) fails to guarantee tightness:
■ Loosen the four screws (6) that lock the filtering chamber
(3) against the vacuum cleaner structure.
■ Allow the filtering chamber (3) to lower down and tighten
the screws (6).Replace the gasket (5) if the degree of
tightness is still not optimum.
■ Check the seal (2) for tightening between the cap (1) and
the filtering chamber (3).
The gaskets must be replaced if they are torn, cut, etc...
