3. Operation modes
When using the grip handle you can
adapt the suction performance by
using the slider to control access of
air into the hose.
3.1 Dry vacuum cleaning
You should only use the vacuum cle-
aner with a dry filter and appropriate
accessories to prevent dust from
accumulating and forming encrusta-
tions. When using the vacuum clea-
ner to remove soot, cement, plaster,
flour or similar dust we recommend
using fleece filter bags. Always use
filter bags in combination with folding
filter cassettes.
NOTE
M, H and H Asbestos class vacuum
cleaners should be preferably used as
dry vacuum cleaners.
3.2 Wet vacuum cleaning
CAUTION
Switch the vacuum cleaner off imme-
diately if foam or liquid starts to
come out.
Empty
the
container
necessary, the folding filter
cassette.
NOTE
Translation of the original instruction
Clean the water level sensors (1) regu-
larly and examine for signs of dama-
ge.
Vacuum cleaning without paper filter
bags. The folding filter cassettes are
designed for wet vacuum cleaning.
The fitted sensor switches the motor
off when the container is full. The
handling of the vacuum cleaner can
be compromised by a full container.
Empty the vacuum cleaner (see "5
Emptying the container").
CAUTION
If the vacuum cleaner is not swit-
ched off, the re-start protection unit
remains operative. Only after swit-
ching off and re-starting is the vacu-
um cleaner ready for use again.
Remove the suction hose from the
liquid before emptying.
After switching off, a small quanti-
ty of water can flow back out of the
hose, as a result of the high suction
level and the favourable flow conditi-
on in the container.
If you use it as a dry vacuum cleaner,
and,
if
you must insert dry filters.
NOTE
If you change between dry and wet
vacuum
recommend using a second set of fil-
ters, preferably polyester folding filter
cassettes.
4. Cleaning the filter
The suction unit is fitted with an
electro-magnetic
device which can shake off any dust
adhered to the folded filter cassettes.
