The specifications apply to a rated voltage [U] of 230 V. These spe-
cifications may vary at different voltages and in country-specific mod-
els.
Values can vary depending upon the product and are subject to ap-
plication and environmental conditions. For further information

These values can differ for other country-specific models. Please take
note of the information on the socket of the dust extractor.
Noise/Vibration Information
Noise emission values determined according to
EN60335-2-69.
Typically the A-weighted sound pressure level of the dust ex-
tractor is 70 dB(A). Uncertainty K=3dB. The noise level
when working can exceed 80dB(A).
Wear hearing protection
Total vibration values ah (triax vector sum) and uncertainty K
determined according to EN60335-2-69: ah<2.5m/s2,
K=1.5m/s2.
Assembly
uPull the plug out of the socket before cleaning or per-
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 holder for the vacuum hose (see
figure A)
– Slide the holder (4) for the vacuum hose firmly into the
corresponding adapters (36) from above until they click
into place.
Fitting the vacuum hose (see figureB)
– Attach the vacuum hose (27) to the hose adapter (3) and
turn it clockwise as far as it will go.
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.
Fitting the vacuuming accessories (see figure C)
The vacuum hose (27) is equipped with a clip system which
can be used to connect vacuuming accessories (dust extrac-
tion adapter (25), curved nozzle (28)).
Fitting the nozzles and tubes
– Push the curved nozzle (28) onto the vacuum hose (27)
until you hear both snap fasteners (37) on the vacuum
hose engage.
– Then attach the required extraction accessory (floor
nozzle, crevice nozzle, suction tube, etc.) firmly to the
curved nozzle (28).
– To remove the accessory, press the snap fasteners (37)
inwards and pull apart the components.
Fitting the dust extraction adapter
– Push the dust extraction adapter (25) onto the vacuum
hose (27) until you hear both snap fasteners (37) on the
vacuum hose engage.
– To remove the adapter, press the snap fasteners (37) in-
wards and pull apart the components.
Inserting/removing the disposal bag or dust bag
(dry extraction) (see figureD)
A disposal bag (29) or dust bag must be used for the dry ex-
traction of dust class M materials.
Insofar as materials with or without an exposure limit of
≥1mg/m3 (dust class L materials) are extracted, these can
be sucked straight into the container.
Note: If using a paper filter bag, you must make sure that
automatic filter cleaning (AFC) is switched off; you should
also do the same if using a fleece filter bag (see " Automatic
filter cleaning (see figure I)", page23).
WARNING The dust extractor contains dust
particles that pose a risk to health.
Emptying and maintenance procedures, including the
disposal of dust containers, should only be carried out by
professionals. Suitable protective equipment is re-
quired. Do not operate the vacuum cleaner unless the
complete filter system is correctly inserted. Otherwise,
you are putting your health at risk.
Inserting the disposal bag
– Open the catches (15) and remove the top part of the va-
cuum cleaner (13).
