4. Use
Note:The flat folding filter must always remain
fitted in the suction unit.
The vacuum cleaner is not suited for sucking up
health-endangering dusts, such as asbestos.
The unit is electrically conductive. Accessories
must be antistatic for this to be effective.
The cleaner has 2 operating modes selectable
via a rotary switch.
Position 1
for dry suction and wet suction

4.1 Automatic Mode via Socket
• When the cleaner is being used in con-
junction with an electric appliance, the latter
is plugged into the grounded outlet of the
cleaner, and the switch is set to position 2.
The cleaner is then automatically switched
on and off with the electrical appliance.
Note:The built-in electronic system has a start-
delay for the suction turbine of 0.5 s and a run-
on time of 15 s. Electrical appliances of 150-
2100 W can be connected.
Attention:
The unit must not be connected if the
connection piece diameter of the dust-ge-
nerating electric tool is larger than the dia-
meter of the suction hose.

Important note:
The unit does not have a low-voltage re-
lease for the integrated socket, therefore
always switch off the electric tool (operating
device) in order to prevent it from uninten-
tionally starting up when the extraction unit
is restarted. DANGER OF ACCIDENTS!
4.2 Dry suction
You can suck up dry dirt without any problem
both with and without a paper filter bag.
We recommend that you always use the paper
filter bag for sucking up fine dirt.
The paper filter bag gives you:
- significantly higher dust holding capacity.
- simple and hygienic dust disposal.
Operation with compressed-air operated
hand-controlled machines
• Rotary switch position 1
When switching on the unit, the dust extractor
must be switched on first, followed by the dust-
generating machine. When switching off the
unit, the sequence is carried out in reverse. The
minimum volumetric flow indicator is set during
automatic operation. If the volumetric flow drops
below the minimum, the signal lamp illuminates.
4.3 Wet suction
• Always work without a paper filter bag.
• Empty the dirt container to prevent sludge
formation.
• The suction unit switches off automatically
when the dirt container is full.
Note: After emptying, press the On/Off switch
twice.
Never suck up explosive liquids (e.g. pet-
rol,diesel fuel, heating oil), acids or sol-
vents!
