General
 We recommend switching off the "Automatic filter
dedusting" function when vacuuming wet dirt with
the crevice nozzle or the upholstery nozzle (option-
al), or when sucking mainly water out of a container.
 The device switches off automatically when the
maximum fluid level is reached.
 When vacuuming non-conductive liquids (e.g. drill
emulsion, oils and grease) the device does not au-
tomatically switch off when the container is full. The
filling level must be continuously monitored and the
container emptied on a timely basis.
 On completion of wet vacuum cleaning: Clean the
main filter element using the filter cleaning. Clean
the electrodes with a brush. Clean the container with
a moist cloth and dry it off.
Clip connection
The suction hose is equipped with a clip system. All ac-
cessory parts with a nominal width of 35 mm can be
connected.

Operation
Turn switch
Switching on the device
1. Connect the mains plug.
2. Set the turn switch to the desired program.
Working with power tools
 DANGER
Danger of electric shock
Risk of injury and damage.
The socket is only intended for direct connection of pow-
er tools to the vacuum cleaner. Any other use of the
socket is prohibited.
1. Plug the mains plug of the power tool into the power
socket on the vacuum cleaner. The vacuum cleaner
is in Standby mode.
2. Switch on the device at the turn switch.
Note
The vacuum cleaner is automatically switched on and
off with the power tool.
Note
The vacuum cleaner has a startup delay of up to 0.5
seconds and an after-running time of up to 15 seconds.
Note
See the Technical data for the permissible power rating
of the power tool.
3. Remove the angle piece from the suction hose.
Illustration K
4. Install the tool adapter on the suction hose.
5. Connect the tool adapter to the power tool.
Illustration L
6. Set the minimum volume flow on the turn switch for
suction hose cross section. The scale shows the
suction hose suction hose cross section.
Note
The different suction hose cross sections are necessary
in order to adapt to the different connection cross sec-
tions of the processing machines.
Note
For operation as a dust removal device for mobile oper-
ation (processing machine plugged into the vacuum
cleaner) the integrated monitoring system must be ad-
justed to suit the connected processing machine (dust
generator). This means that the user must be warned
when the flow rate drops below the minimum value 20
m/s needed for correct vacuuming.
Automatic filter dedusting
The device is equipped with a special filter dedusting
function, which is particularly effective against fine dust.
The main filter element is automatically cleaned every
7.5/15/60 seconds (depending on use) using an airflow
(pulsing sound).
1. Set the turn switch to program 2 (TACT AUTO).
Device OFF
 Device ON
 Automatic filter dedusting: OFF
 Adjust the suction performance (min-
max)
 Device ON
 Automatic filter dedusting: ON
 Adjust the suction performance (min-
max) (eco = energy-saving mode)
