pleated filter, an audible alarm signal will sound. In this case,
switch off the dust extractor and check it as described in the
"Rectifying faults" section.
Extracting dust that accumulates from working power
tools (see figure G)
There must be a sufficient air exchange rate (L) 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 electric socket with a protective
earth contact (5), which can be used to connect an external
power tool. Observe the maximum permitted load of the
connected power tool.
In order for sufficient dust transport to be ensured at the ex-
traction point, the volume flow must not fall below the min-
imum specified for the connected power tool.

– Adjust the volume flow controller (6) to suit the hose dia-
meter used.
– Fit the dust extraction adapter (23).
– Insert the dust extraction adapter (23) into the extraction
outlet of the power tool.
Note: When working with power tools that have a low air
feed into the vacuum hose (e.g. jigsaws, sanders, etc.), the
false air intake (36) of the dust extraction adapter (23) must
be opened. This will ensure that the automatic filter cleaning
function works correctly.
To do this, turn the ring above the false air intake (36) until
the opening is at its maximum size.
– To activate the automatic start/stop
function of the dust extractor, set the
mode selector switch (7) to the "auto-
matic start/stop" symbol.
In this operating mode, the volume flow is
electronically monitored according to the
setting of the volume flow controller (6).
Having the correct setting selected en-
sures sufficient dust transport.
– To start the dust extractor, switch on the power tool
connected to the plug socket (5). The dust extractor 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 seconds longer in order to extract the remaining
dust from the vacuum hose.
– To switch off the dust extractor, set the
mode selector switch (7) to the "switch
off" symbol.
If the acoustic warning signal sounds, the dust extractor
must be checked as described in the "Rectifying faults" sec-
tion.
Bosch Power Tools
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 H) have only been verified for dry extraction.
Steps to Take before Wet Vacuuming
– Remove the disposal bag (27) or the safety filter bag (26)
if necessary.
Volume flow setting
Note: Use a wet filter bag (accessory), which separates li-

quid from solids, to make disposal easier when vacuuming
3 water-solid mixtures.
41.2 m /h
– Place the rubber lip (30) into the floor nozzle (32).
3
12.7 m /h
– Switch off the automatic filter cleaning (AFC).
Vacuuming up liquids
– To switch on the dust extractor, set the mode selector
switch (7) to the "extraction" symbol.
The dust extractor is equipped with fill level sensors (40).
The dust extractor shuts down if the maximum fill level has
been reached. Set the mode selector switch (7) to the
"switch off" symbol.
Note: When extracting non-conductive liquids (e.g. drilling
emulsion, oils and fats), the dust extractor will not switch off
when the container is full. The fill level must be constantly
monitored and the container emptied in good time.
If the acoustic warning signal sounds during wet extraction,
the operating reliability of the dust extractor is not affected.
No measures to rectify the fault are necessary.
– To switch off the dust extractor, set the mode selector
switch (7) to the "switch off" symbol.
– To transport the dust extractor, screw the sealing plug (2)
onto the hose adapter (3).
– Empty the container (1).
To prevent mould growth after wet extraction:
– Remove the flat-pleated filter (28) and leave this to dry
thoroughly.
– Remove the top part of the dust extractor (12), open the
filter cover (39) and leave both elements to dry thor-
oughly.
Automatic filter cleaning (see figure H)
When automatic filter cleaning (AFC) is active, the flat-
pleated filter (28) is cleaned every 15 seconds using blasts
of air (pulsating noise).
The filter cleaning function should be activated at the very
latest when the suction power is no longer sufficient.
Regular use of the filter cleaning function will increase the
service life of the filter.
