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 with the knob (1, Fig. 10).
If the vacuum cleaner is equipped with electric filter shaker,
press and hold for a few seconds the button (6, Fig. 6). When
releasing the button, the filter shaker stops.
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 filter replacement"
paragraph).
