– Put the top part of the vacuum cleaner (10) on and close
the catches (9).
Note: Ensure that the filter is always fitted correctly. This is
particularly important when vacuuming hazardous dust.
Removing/Inserting the Wet Filter
To make disposal easier when vacuuming water-solid mix-
tures, the vacuum cleaner has a wet filter (21) that separ-
ates the liquid from the solids.
Removing the wet filter (see figure F1)
– Open the catches (9) and remove the top part of the va-
cuum cleaner (10) (see figure C).

tion of rotation and take the filter holder, together with
the main filter (20), out of the top part of the dust
extractor (10).
– Pull the wet filter (21) out of the filter basket (30).
Inserting the wet filter (see figure F2)
– Place the wet filter (21) completely over the filter basket
(30).

the catches (9).
Inserting/removing the plastic bag or dust bag
(dry vacuuming)

cuum cleaner (10) (see figure C).
– Take the pre-filter (22) out of the container (7) by its
handle (28).

inlet facing upwards. Secure the plastic bag under the
suction hole (31) using the clips (32).
– Make sure that the plastic bag (19) touches all the inside
walls of the container (7).
– Fold the rest of the plastic bag (19) over the edge of the
container (7).
– Insert the pre-filter (22) in the container (7), making sure
that the arrow is pointing towards the hose connection
piece (3).

nection flange. Make sure that the entire length of the
dust bag touches the inside wall of the container (7).

Operation
Pull the plug out of the socket before cleaning or per-
u
forming maintenance on the vacuum cleaner, making
tool adjustments, changing accessories or putting
away the vacuum cleaner. This safety measure prevents
the vacuum cleaner from being started accidentally.
When operating the dust extractor, ensure that the lockable
castors on the dust extractor are blocked to prevent the dust
extractor from rolling away unintentionally. Test the correct
functioning of the castors on the relevant surface before op-
eration.
Start-up
Pay attention to the mains voltage. The voltage of the
u
power source must correspond with the data on the type
plate of the vacuum cleaner.
Make sure you inform yourself about the applicable
u
regulations/laws on how to handle harmful types of
dust in your country.
The dust extractor must categorically not be used in poten-
tially explosive areas.
