Primary filter shaker
According to the quantity of vacuumed material, if the
vacuum gauge pointer ( 2 , Fig. 7 ) goes from the green
zone ( 3 , Fig. 7 ) to the red zone ( 1 , Fig. 7 ), shake
the primary filter by turning the lever ( 4 , Fig. 5 )
clockwise/counterclockwise for at least 5 complete
cycles.
WARNING!
Stop the vacuum cleaner before using the
filter shaker.
Do not shake the filter while the vacuum
cleaner is on, as this could damage the filter.
Wait before restarting the vacuum cleaner, to allow
the dust to settle. Replace the filter element if the
vacuum gauge pointer stays in the red zone ( 1 ,
Fig. 7 ) even after the filter has been shaken (see
“Primary filter replacement”).

cleaner stops.
WARNING!
The motors and internal components of
the vacuum cleaner will still be electrically
powered.
To start the vacuum cleaner again, turn the buttons of
each single motor ( 1 and 2 , Fig. 5 ) to “I”.
