– To remove the adapter, press the snap fasteners (24) in-
wards and pull apart the components.
Fitting the holder for the vacuum hose (see
figure B)
– Slide the holder (14) for the vacuum hose (17) firmly into
the adapter (25) provided for it from above until it clicks
into place.
Fitting the vacuum hose (see figure C)
– Insert the vacuum hose (17) firmly into the hose
adapter (2).
Note: The friction generated by the dust in the vacuum hose
and accessory during extraction causes an electrostatic
charge that the user may experience as static discharge (de-
pending on environmental factors and their physiological
state).
Bosch generally recommends using an anti-static vacuum
hose (accessory) to vacuum up fine dust and dry materials.
Inserting/removing the disposal bag or dust bag
(dry vacuuming) (see figures D1–D2)
For dry vacuuming, you can insert a disposal bag (20) or a
dust bag (accessory) into the container (1). This makes the
dust easier to dispose of.
Inserting the disposal bag
– Open the catches (7) and remove the top part of the va-
cuum cleaner (6).
– Insert the disposal bag (20) into the container (1) with
the inlet facing forwards.
– Pull the inlet over the connection flange and all the way
into the recess of the connection flange.
– Make sure that the disposal bag (20) touches all the in-
side walls of the container (1).
– Fold the rest of the disposal bag (20) over the edge of the
container (1).
– Put the top part of the vacuum cleaner (6) on and close
the catches (7).
Removing and sealing the disposal bag
– Open the catches (7) and remove the top part of the va-
cuum cleaner (6).
– Pull the full disposal bag (20) backwards out of the con-
nection flange.
– Carefully take the disposal bag (20) out of the
container (1) without damaging it.
When doing so, make sure that the disposal bag does not
scrape against the connection flange or other sharp ob-
jects.
– Tie up the disposal bag (20) below the inlet.
Changing/inserting the dust bag (accessory)
– Open the catches (7) and remove the top part of the va-
cuum cleaner (6).

– Pull the full dust bag backwards out of the connection
flange. Close the opening in the dust bag by turning down
the top. Take the closed dust bag out of the container (1).
– Place the new dust bag over the vacuum cleaner's con-
nection flange. Make sure that the entire length of the
dust bag touches the inside wall of the container (1).
– Put the top part of the vacuum cleaner (6) on and close
the catches (7).
Operation
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.
When operating the dust extractor, ensure that the
castors (9) blocked with the castor brakes (10) to prevent
the dust extractor from rolling away unintentionally. Test the
correct functioning of the wheels (8) and castors (9) on the
relevant surface before operation.
Start-up
Pay attention to the mains voltage. The voltage of the
u
power source must correspond with the information on
the type plate of the dust extractor. Dust extractors
marked with 230 V can also be operated with 220 V.
Make sure you inform yourself about the applicable
u
regulations/laws on how to handle harmful types of
dust in your country.
The dust extractor may be used for vacuuming and extract-
ing the following materials:
– Dusts with an exposure limit of > 1 mg/m
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
The dust extractor must categorically not be used in poten-
tially explosive areas.
To ensure optimum suction power, you must always fully un-
wind the vacuum hose (17) from the top part of the dust ex-
tractor (6).
Dry vacuuming
Vacuuming up Dust Deposits
– To switch on the dust extractor, briefly press the on/off
button (4).
– To switch off the dust extractor, press the on/off
button (4) again.
Extracting dust that accumulates from working power
tools (see figure E)
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 (3), which can be used to connect an external
