Shaking the primary filter

Figure 9-10
Depending on the vacuumed dust quantity and if the pointer
of the vacuum gauge switches from the green zone (3, Fig. 9)
to the red zone (2, Fig. 9), turn the vacuum cleaner off and
shake the main filter using the knob (1, Fig. 10).
WARNING!
Stop the vacuum cleaner before shaking the filter.
Do not shake the filter while the vacuum cleaner is on,
as this could damage the filter itself.
Wait a few seconds before restarting the vacuum cleaner, to
allow the dust to settle. Replace the filter element if the pointer
still remains in the red zone (1, Fig. 9) even after the filter has
been shaken (consult the "Primary star filter replacement"
paragraph).

Emergency stopping

Turn the manual motor starter to the "0" position.

Emptying the container

WARNING!
Before proceeding with these operations, turn off the
vacuum cleaner and remove the plug from the power
socket.
Before emptying the container it is advisable to clean the filter
(see "Shaking the primary filter" paragraph).

Polyliner

An antistatic polyliner can be used to collect dust (see Fig. 11).
In this case, the vacuum cleaner must be equipped with
optional accessories [depressor (3) and grid (2), Fig. 11].
