Primary filter shaker

According to the quantity of vacuumed material, if the vacuum
gauge pointer (2) goes from the green zone (3) to the red
zone (1), shake the primary filter by turning the lever (4,
Fig. 3) clockwise/counterclockwise for at least 5 complete
cycles.
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) even after the filter has been shaken
(see "Primary filter replacement").

Emergency stopping

Turn the buttons (1 and 2 Fig. 3) to "OFF". The vacuum
cleaner stops.
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. 3) to "ON".

vacuum cleaner off and disconnect the plug from

Emptying the liquid container

■ The filter element will be wet after liquids have been
vacuumed.
A wet filter element can quickly become clogged if the vacuum
cleaner is then used to vacuum dry substances.
For this reason, make sure that the filter element is dry or
replace it with another one before using the vacuum cleaner
for dry materials.

Replacement of dust bags

Before proceeding with these operations, turn off the
vacuum cleaner and remove the plug from the power
socket.
■ These operations can only be carried out by
trained and qualified personnel who must wear
adequate clothing, in compliance with the laws in
force.
■ Take care not to raise dust when this operation is
carried out. Wear an N100 (P3) protective mask.
■ In case of hazardous and/or harmful dust, use
only the bags recommended by the manufacturer
(see "Recommended spare parts").
■
The bag must only be disposed of by qualified
personnel and in compliance with the laws in
force.
Installing a paper bag not suitable for the class of dust
to be vacuumed, or incorrect installation, can create a
health risk for people exposed.
