Extracting dust that accumulates from working power
tools (see figure K)
There must be a sufficient air exchange rate in the
u
room when the exhaust air comes back into the room.
Be aware of the corresponding national regulations.
The dust extractor has an integrated plug socket for power
tools (4), which can be used to connect an external power
tool. Observe the maximum permitted load of the connected
power tool.
Fit the combi power tool adapter (27) (see figure B).
Insert the combi power tool adapter (27) into the extraction
outlet of the power tool.
To switch on the automatic start/stop feature
of the dust extractor, turn the main switch (2)
to position 1+.
To start the dust extractor, switch on the
power tool connected to the plug socket (4). The dust ex-
tractor will start automatically.
To stop dust extraction, switch the power tool off.
The automatic start/stop run-on function will run for up to
15 s longer in order to extract the remaining dust from the
vacuum hose.
To switch off the dust extractor, turn the
main switch (2) to position 0.
Using the extraction system (accessory)
Connect the extraction system to the vacuum
hose (30).
To extract dust via the extraction system,
turn the main switch (2) to position 1.
Hold the extraction system up to the wall and switch on the
power tool. The negative pressure this creates causes the
extraction system to stick to the wall independently.
Switch off the power tool and carefully remove the extrac-
tion system from the wall.
To switch off the dust extractor, turn the
main switch (2) to position 0.
Wet vacuuming
Do not use the vacuum cleaner to vacuum combustible
u
or explosive liquids, such as petrol, oil, alcohol or
solvents. Do not vacuum hot, burning or explosive
dust. Do not operate the vacuum cleaner in areas sub-
ject to explosion hazards. Dust, vapours and liquids can
ignite or explode.
The vacuum cleaner must not be used as a water
u
pump. The vacuum cleaner is designed for vacuuming air
and vacuuming water mixtures.
Note: The requirements for the degree of penetration (dust
class M) have only been verified for dry extraction.
Bosch Power Tools
Before Starting Wet Extraction
Empty the container (1) and remove the fleece filter
bag (33).
Check the fill level sensor (43) for dirt. The fill level sensor
must be clean in order for the dust extractor to switch off
automatically when the container is full (see "Cleaning the fill
level sensor (see figures P–Q)", page 27).
During wet extraction, the automatic filter cleaning
u
function must be deactivated.
Press the automatic filter cleaning button (10) to activate
manual filter cleaning (see "Manual Filter Cleaning",
page 26). This deactivates automatic filter cleaning and
LED indicator A (5) goes out.
Vacuuming up liquids
If you notice a foam or water leak,
WARNING
switch off the vacuum cleaner im-
mediately and empty the container. Otherwise, the va-
cuum cleaner can become damaged.
To switch on the dust extractor, turn the main switch (2) to
position 1.
The dust extractor is equipped with fill level sensors (43). If
the maximum fill level has been reached, the dust extractor
automatically switches off and the two LED indicators A (5)
and M (6) flash simultaneously once a second. Restart pro-
tection is activated and can be deactivated by switching the
dust extractor on and off once.
Note: Check the fill level regularly and empty the container
in good time. If, during wet extraction, an acoustic warning
signal sounds, no measures are necessary. The operational
safety of the dust extractor is not impaired.
To switch off the dust extractor, turn the main switch (2)
to position 0.
Hold the container (1) in the rear handle section (25) and
twist it forwards to drain the liquid.
After Wet Extraction
After wet vacuuming, always clean the fill level
sensor (43) (see "Cleaning the fill level sensor
(see figures P–Q)", page 27).
To prevent mould growth after wet extraction:
– Remove the flat-pleated filter (34) and leave this to dry
thoroughly.
– Remove the top part of the dust extractor (16), open the
filter cover (40) and leave both elements to dry thor-
oughly.
Automatic/Manual Filter Cleaning (see figure L)
Automatic Filter Cleaning
Note: The automatic filter cleaning function is set to be on by
default when the dust extractor is switched on.
The LED indicator A (5) will light up continuously.
When the automatic filter cleaning function is active, the flat-
pleated filter (34) is cleaned by two blasts of air (pulsating
noise). This activates as soon as the sensor detects that the
airflow has dropped below a specific level.
