- Filter replacement (fig. 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 filter shaker
knob "B".
- Release the fastening latches "C" and remove
the complete head "D"; then, lift the filter "E" and
remove the clamp "F", which holds the filter onto
the support ring "G".
- Remove the cage "H" and turn the filter upside
down.
- Untie the clamps "I" and detach the cage from the
filter.
- Dispose of the filter according to the laws in force.
- Fit the new filter 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 fixed (fig. 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 figure 11.
- Cover tightness check
If the gasket "A" (fig. 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" (fig. 12) if the degree of
tightness is still not optimum.
- Filtering chamber tightness check
If the gasket "A" (fig. 13) between the container and
the filtering chamber "C" fails to guarantee tightness,
proceed as follows:
- Loosen the four screws "B", which 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., 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.
