– Insert the dust extraction adapter (16) 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 (33) of the dust extraction adapter (16) must
be opened. This will ensure that the semi-automatic filter
cleaning function works correctly.
To do this, turn the ring above the false air intake (33) until
the opening is at its maximum size.
– To activate the automatic start/stop
function of the dust extractor, set the
mode selector switch (1) to the "auto-
matic start/stop" symbol.
– To start the dust extractor, switch on the power tool
connected to the plug socket (2). 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 6 seconds longer in order to extract the remaining
dust from the vacuum hose.
– To switch off the dust extractor, set the
mode selector switch (1) to the "switch
off" symbol.

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: When wet vacuuming, ensure that the main filter (20)
is removed from the vacuum cleaner.
Steps to Take Before Wet Vacuuming
– Open the catches (9) and remove the top part of the va-
cuum cleaner (10) (see figure C).
– Take the pre-filter (22) out of the container (7) by its
handle (28).
– Remove the plastic bag (19) or dust bag if necessary.
– Turn the filter holder (29) as far as possible in the direc-
tion of rotation and take the filter holder, together with
the main filter (20), out of the top part of the vacuum
cleaner (10).
– Place the wet filter (21) completely over the filter basket
(30).
– Insert the pre-filter (22) back in the container (7), mak-
ing sure that the arrow is pointing towards the hose con-
nection piece (3).
Ensure that the wet filter (21) lies completely over the fil-
ter basket (30).
– Put the top part of the vacuum cleaner (10) on and close
the catches (9).
Bosch Power Tools
– Place the rubber lip (23) in the floor nozzle (25).
Vacuuming up liquids
– Switch on the dust extractor (set the mode selector
switch (1) to the "extraction" symbol).
The dust extractor is equipped with a float. Extraction is
stopped when the maximum filling level is reached.
– Set the mode selector switch (1) to the "switch off" sym-
bol.
– Empty the container (7).
To prevent mould growth after wet extraction: (see "Clean-
ing the wet filter", page 22)
Semi-automatic filter cleaning
The filter cleaning function should be activated at the very
latest when the suction power is no longer sufficient.
How often filter cleaning needs to be carried out will depend
on the type and quantity of dust that has been extracted.
With regular use, the maximum conveying capacity will be
maintained for longer.
– Switch the dust extractor off for 6–10 seconds and then
on again. Repeat this several times in succession.
The pre-filter (22) is cleaned using blasts of air when it is
switched off.
– To work after cleaning the filter, switch the dust extractor
back on.

Maintenance and Service

Maintenance and Cleaning

Pull the plug out of the socket before cleaning or per-
u
forming maintenance on the vacuum cleaner, making
tool adjustments, changing accessories or putting
away the vacuum cleaner. This safety measure prevents
the vacuum cleaner from being started accidentally.
To ensure safe and efficient operation, always keep
u
the dust extractor and the ventilation slots clean.
Wear a dust mask when servicing and cleaning the va-
u
cuum cleaner.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.
For the user to carry out maintenance, the dust extractor
needs to be disassembled, cleaned and maintained as far as
this is possible without endangering maintenance personnel
or other persons. Before disassembly, the dust extractor
should be cleaned to prevent any potential hazards. The
room/enclosure in which the dust extractor is disassembled
should be well ventilated. Wear personal protective equip-
ment while carrying out maintenance. After completing
maintenance, the maintenance area should be cleaned.
An inspection regarding the dust extraction capability must
be carried out at least once a year by the manufacturer or
someone who has been trained, e.g. to check for filter dam-
age, that the dust extractor is tight and that the control unit
