Noise/Vibration Information
Noise emission values determined according to
EN 60335-2-69.
Typically the A-weighted sound pressure level of the dust ex-
tractor is 71 dB(A). Uncertainty K = 2 dB. The noise level
when working can exceed the volume stated. Wear hearing

Assembly
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.
Fitting the vacuuming accessories (see figure A)
The vacuum hose (17) is equipped with a clip system which
can be used to connect vacuuming accessories (dust extrac-
tion adapter (18), curved nozzle (19)).
Fitting the nozzles and tubes
– Push the curved nozzle (19) onto the vacuum hose (17)
until you hear both snap fasteners (24) on the vacuum
hose engage.
– Then attach the required extraction accessory (coarse
dirt nozzle, crevice nozzle, suction tube, etc.) firmly to
the curved nozzle (19).
– To remove the adapter, press the snap fasteners (24) in-
wards and pull apart the components.

Fitting the dust extraction adapter
GAS 20 L SFC
– Push the dust extraction adapter (18) onto the vacuum
/I
hose (17) until you hear both snap fasteners (24) on the
IPX4
vacuum hose engage.
IP55
– 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)
100 W
– Insert the vacuum hose (17) firmly into the hose
100 W
adapter (2).
100 W
Note: The friction generated by the dust in the vacuum hose
100 W
and accessory during extraction causes an electrostatic
100 W
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.
