- Filter replacement (fi g. 10)
Before proceeding with these operations, turn off the
vacuum cleaner and remove the plug from the power
socket.
- Release the stop "A" and unscrew the fi lter shaker
knob "B".
- Release the fastening latches "C" and remove
the complete head "D"; then, lift the fi lter "E" and
remove the clamp "F", which holds the fi lter onto
the support ring "G".
- Remove the cage "H" and turn the fi lter upside
down.
- Untie the clamps "I" and detach the cage from the
fi lter.
- Dispose of the fi lter according to the laws in force.
- Fit the new fi lter and secure it in the cage with
special clamps.
- Assemble the components in the reverse order of
disassembly.

- 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" is in good condition and
correctly fi xed (fi g. 11).
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 in the dust
container.
Scrape the inlet from the outside and remove the
deposited waste as indicated in fi gure 11.
- Cover tightness check
If the gasket "A" (fi g. 12) under the complete head "D"
has become slack, unscrew the screws "B", which lock
the fastening latches "C" in place, and allow the latter
to slide downwards until the complete head "D" closes
perfectly.
Now tighten the locking screws "B".
Replace the gasket "A" (fi g. 12) if the degree of
tightness is still not optimum.
- Filtering chamber tightness check
If the gasket "A" (fi g. 13) between the container and
the fi ltering chamber "C" fails to guarantee tightness,
proceed as follows:
- Loosen the four screws "B", which lock the fi ltering
chamber "C" against the vacuum cleaner structure.
- Allow the fi ltering 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., or if
the degree of tightness is still not optimum.

- Vacuum cleaner disposal

Dispose of the vacuum cleaner in compliance with the
laws in force.
