– Pull the edge of the full plastic bag (19) backwards out of
the clips (31).
– Carefully take the plastic bag (19) out of the container

that the arrows are pointing towards the hose connection
piece (3).
– Put the top part of the vacuum cleaner (10) on and close
the catches (9).
Fitting the rubber lip (wet vacuuming) (see
figure H)
Note: The requirements for the degree of penetration (dust
class L) have only been verified for dry vacuuming.
– Use a suitable tool to lift the brush inserts (24) out of the
floor nozzle (25).
– Place the rubber lips (23) in the floor nozzle (25).
Note: The textured side of the rubber lips must be facing
outwards.
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.
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. Chargers labelled as
230 V can also be operated with 220 V.
1 609 92A 4CP | (09.11.2018)
Pay attention to the mains voltage. The voltage of the
u
power source must correspond with the data on the type
plate of the vacuum cleaner.
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 (15) from the top part of the dust ex-
tractor (10).
Dry vacuuming
Note: Make sure that both the pre-filter (22) and the main
filter (20) are inserted in the vacuum cleaner when carrying
out dry vacuuming (see also figures D2 and E2).
Extracting dust deposits
– To switch on the dust extractor, set the
mode selector switch (1) to the "extraction"
symbol.
– To switch off the dust extractor, set the
mode selector switch (1) to the "switch off"
symbol.
Extracting dust that accumulates from working power
tools (see figure I)
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 (2) that can be used to
connect an external power tool. Observe the
maximum permitted connected load of the con-
nected power tool.
– Fit the extraction adapter (16) (see "Fitting the dust ex-
traction adapter", page 18).
– Insert the extraction adapter (16) into the dust extraction
outlet of the power tool.
Note: When working with power tools that have a low air
feed into the vacuum hose (e.g. jigsaws, sanders, etc.), the
false air intake (32) of the dust extraction adapter (16) must
be opened. This will ensure that the automatic filter cleaning
function works correctly.
To do this, turn the ring above the false air intake (32) until
the opening is at its maximum size.
– To activate the automatic start/stop
function of the dust extractor, set the
mode selector switch (1) to the "auto-
matic start/stop" symbol.
