PICKING UP DRY
SUBSTANCES
Before picking up dry
substances, the bag-type
filter should always be
installed in the tank. It is
then easy to dispose of
the material picked up
and the service life of the
main filter element is
significantly increased. Dry
cleaning without bag-type
filter is also possible.
Inflammable substances
must not be picked up
with the cleaner!
After picking up liquids,
the filter element is damp.
Damp filter elements can
clog more quickly when
dry substances are picked
up. For this reason, the
filter element should be
dried or replaced by a dry
element before picking up
dry substances.
PICKING UP LIQUIDS
Before picking up liquids,
the bag-type filter must
always be removed from
the tank.
Inflammable liquids
must not be picked up
with the cleaner!
If foaming is observed,
stop work immediately
and empty the tank.

SWITCHING ON THE
CLEANER
SQ 450/550/650-11:
• Turn the switch to
position 'I' (Fig. 5).
SQ 450-21/-31
and SQ 550/650-31:
Two operating modes are
possible:
Switch position 'I':
The cleaner motor starts
immediately.
Switch position 'auto':
The cleaner motor starts
only when the tool
connected to the
appliance plug socket is
switched on (Fig. 6).
CAUTION!
Before turning the
switch to position
'auto', ensure that the
tool connected to the
appliance plug socket is
switched off.
The motor speed and thus
the suction power can be
varied at the suction force
regulator 1) . This permits a
precise adaptation to
different substances to be
picked up (Fig. 6).
AFTER FINISHING WORK
• Switch off the cleaner
and pull the plug of
the mains lead out of
the plug socket.
• Wind up the mains
lead (Fig. 7).

on the filter).
IMPORTANT!
Push the bag-type
filter sleeve completely
onto the inlet fitting.
REPLACING THE FILTER
ELEMENT
