Application

Vacuuming dry materials

Before using the vacuum cleaner to evacuate dry
substances, a fi lter bag must always be inserted
in the container. Then the evacuated material can
be disposed of easily.
The fi lter element becomes damp after evacuating
liquids. A damp fi lter element suffers more wear
and tear if it is used for dry materials. Accordingly,
the fi lter element should be dried or replaced with
a dry one before dry operation.

Vacuuming liquids

Do not evacuate combustible liq-
uids!
If foam or liquid escapes, stop work
immediately and empty the dirt container.
The HEPA fi lter element shall only be
used for extracting dry materials.
The fi lter bag has to be removed before evacuat-
ing liquids. We recommend use of a special wet
fi lter (452924).
When the maximum fi lling level is reached, a
bag-full indicator (2.12) automatically interrupts
extraction.
Changing the fi lter
During the following procedure, take
care not to raise dust more than is unavoidable.
Moisten the fi lter element with a water spray be-
fore removing it.
Check the fi ll level of the fi lter bag at regular
intervals. A full fi lter bag shall be replaced im-
mediately.
Check the fi lter element for damage every time
the fi lter bag is changed. Replace damaged fi lter
elements immediately.
Always insert a fi lter bag when using a HEPA fi lter
element.
