Dry vacuuming
Extracting dust deposits
– To switch on the dust extractor, set the mode selector
switch (4) to the "On" symbol.
– To switch off the dust extractor, set the mode selector
switch (4) to the "Off" symbol.
Extracting dust that accumulates from working power
tools (see figure B)
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 a plug socket with a protective earth
contact that can be used to connect an external power tool.
Observe the maximum permitted connected load of the con-
nected power tool.
– Set the mode selector switch (4) to the
"operation with remote automatic
switching" symbol.
Different hose connection systems are available as accessor-
ies for power tools.
– To start the dust extractor, switch on the power tool con-
nected to the plug socket (5). The dust extractor will start
automatically.
– Switch the power tool off to switch off the dust extractor.
The dust extractor automatically switches off approx.
6 seconds later.
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.
Steps to Take before Wet Vacuuming
– If necessary, remove the dust bag (11) and empty the
container (9).
Note: Use a wet filter bag (accessory), which separates li-
quid from solids, to make disposal easier when vacuuming
water-solid mixtures.
Vacuuming up liquids
– To switch on the dust extractor, set the mode selector
switch (4) to the "On" symbol.
– The dust extractor is equipped with fill level sensors (14).
The dust extractor shuts down if the maximum fill level
has been reached.
Set the mode selector switch (4) to "Off".
Note: When extracting non-conductive liquids (e.g. drilling
emulsion), the dust extractor will not switch off when the
Bosch Power Tools
container is full. The fill level must be constantly monitored
and the container emptied in good time.
– To switch off the dust extractor, set the mode selector
switch (4) to the "Off" symbol.
– Empty the container (9).
To prevent mould growth after wet extraction:
– Remove the pleated filter (12) and leave this to dry thor-
oughly.
– Remove the top part of the dust extractor (3) and leave it
to dry thoroughly.
Electromagnetic filter cleaning (SFC)
The tool is equipped with electromagnetic filter cleaning,
which removes dust adhering to the pleated filter (12).
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.
– Set the mode selector switch (4) to the "electromagnetic
filter cleaning (SFC)" symbol. Any power tools connected
must be switched off.
The dust extractor vibrates for approx. 10 seconds and
automatically switches off.
– Wait briefly before resuming suction to allow the dust to
settle in the container.

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-
