WARNING!
[ NOTE ]

Liquids vacuuming

Make sure that the vacuum cleaner is equipped with a liquid
level sensor and is suitable for vacuum liquids.
Do not vacuum flammable liquids.
If foam forms, turn off the vacuum cleaner immediately and
empty the 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.

At the end of a cleaning session

■
Turn off the vacuum cleaner and remove the plug from
the socket.
■ Wind the connection cable around the cable carrier (Fig.

■ Empty the container as described in the "Emptying the
container" paragraph.
Clean the vacuum cleaner as described in the
"Maintenance, cleaning and decontamination" paragraph.
■ Wash the container with clean water if aggressive
substances have been vacuumed.
■ Store the vacuum cleaner in a dry place, out of reach of
unauthorized people.
■ Shut the inlet with the appropriate plug when the vacuum
cleaner is transported or not being used (particularly in
the case of M, H and asbestos versions) (1, Fig. 14).
