it.

unit which complies with the laws in force and seal
the cover again hermetically.
Assembly
Assemble in this order:
- the absolute filter;
- nut and central knob for locking;
- the deck, blocking it using the hooks "C".

Motor cooling fan inspection and cleaning

Periodically clean the motor cooling fan to prevent
the motor from overheating, especially if the vacuum
cleaner is used in a dusty place.

Tightness inspection

Hoses check
Check that the hose "A" (fig. 15) is in 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, 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 figure 15.
Cover tightness check
If the gasket "A" (fig. 11) under the cover "D" has
become slack, unscrew the screws "B" that lock the
closing hooks "C" in place and allow them to slide
downwards until the deck "D" closes perfectly.
Now tighten the locking screws "B".
Replace the gasket "A" - fig. 11 if the degree of
tightness is still not optimum.
Filtering chamber tightness check
If the gasket "A" - fig. 12 between the container and
the filtering chamber "C" fails to guarantee tightness:
- loosen the four screws "B" that lock the filtering
chamber "C" against the vacuum cleaner
structure;
- allow the filtering chamber "C" to lower down and
tighten the screws "B" once it has reached the
tightness position.
The gasket must be replaced if it is torn, cut, etc...
Replace the gasket "A" if the degree of tightness is still
not optimum.
