Operating modes

When using the grip handle you can adapt the suction performance
by using the slider to control access of air into the hose.

6.1 Dry vacuum cleaning

You should only use the vacuum cleaner with a dry filter and appro-
priate accessories to prevent dust from accumulating and forming
encrustations.
When using the vacuum cleaner 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.
M, H and H Asbestos class vacuum cleaners should be
preferably used as dry vacuum cleaners.

6.2 Wet vacuum cleaning

l CAUTION!
Switch the vacuum cleaner off immediately if foam or liquid starts
to come out.
▷ Empty the container and, if necessary, the folding filter
cassette.
Clean the water level sensors (1) regularly
and examine for signs of damage.

▶ 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

mised by a full container.
▶ Empty the vacuum cleaner
l CAUTION!
If the vacuum cleaner is not switched off, the re-start protection
unit remains operative. Only after switching off and re-starting is
the vacuum cleaner ready for use again.
