tractor is 73 dB(A). Uncertainty K = 2 dB. The noise level
when working can exceed the volume stated. Wear hearing
protection!

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 (27) has a clip system that can be used to
connect vacuuming accessories (combi power tool
adapter (23), curved nozzle (28), combi brush nozzle
(22)).
Fitting the curved nozzle
– Push the curved nozzle (28) onto the vacuum hose (27)
until you hear both snap fasteners (32) on the vacuum
hose engage.
– To remove the adapter, press the snap fasteners (32) in-
wards and pull apart the components.
Fitting the combi power tool adapter
The combi power tool adapter (23) consists of the Power-
Tool adapter (front part) (33) and the PowerTool adapter
(rear part) (34).
The combi power tool adapter (23) is compatible with Bosch
power tools.
With an inner diameter of 38.5 mm and an outer diameter of
45 mm, the PowerTool adapter (rear part) (34) can be used
for power tools manufactured by other brands.
Place the PowerTool adapter (front part) (33) on the Power-
Tool adapter (rear part) (34) and connect both adapters by
twisting them in opposite directions (see figure B).
Push the combi power tool adapter (23) onto the vacuum
hose (27) until you hear both push buttons (32) on the va-
cuum hose click into place.
To remove the adapter, press the push buttons (32) inwards
and pull the combi power tool adapter out of the vacuum
hose.
To separate the two adapters, loosen the connection by
twisting in opposite directions and pulling the adapters
apart.
Fitting the Combi Brush Nozzle
Push the combi brush nozzle (22) onto the vacuum
hose (27) until you hear both push buttons (32) on the va-
cuum hose click into place.

To remove the adapter, press the snap fasteners (32) in-
wards and pull apart the components.
Adjusting the Combi Brush Nozzle (see figure C)
You can use the combi brush nozzle (22) as a crevice nozzle
or brush.
Press the release button (35) and push the brush forwards
to use the combi brush nozzle (22) as a brush.
Press the release button (35) and pull the brush backwards
to use the combi brush nozzle (22) as a crevice nozzle.
Fitting the vacuum hose (see figure D)
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.
Attaching the Vacuum Hose to the Dust Extractor
(see figure E)
Wrap the fitted vacuum hose (27) into the compartment for
the vacuum hose. Pull up both pull straps (13) and hook
them into the fastening openings (14).
Inserting/removing the plastic bag (dry
extraction) (see figure F)
Open both catches (15) and remove the top part of the dust
extractor (12).
For dry extraction, insert a plastic bag (29) into the
container (1).
Insert the plastic bag (29) into the container (1) with the in-
let facing upwards.
Make sure that the plastic bag (29) touches all the inside
walls of the container (1).
Fold the rest of the plastic bag (29) over the edge of the con-
tainer (1). Make sure that the stop line of the plastic bag is
positioned at the edge of the container and the air passage
openings (30) are still in the container.
Put the top part of the vacuum cleaner (12) back on and
close the vacuum cleaner using the catches (15).
Ensure that the dust extractor is always properly
u
closed.
Seal the plastic bag before you remove it. Hold the bag to-
gether at the top and use a cord to tie up the bag.
Inserting/Removing the Fleece Filter Bag (Dry
Extraction) (see figures G-H)
A fleece filter bag (37) (accessory) must be used for the dry
extraction of dust class L materials.
Insofar as materials with or without an exposure limit of
3
≥ 1 mg/m (dust class L materials) are extracted, these can
be sucked straight into the container.
