– Pull the full safety filter bag (26) backwards out of the
connection flange.
– Seal the opening of the safety filter bag by pushing the
closing flap over the opening.
– Seal the black plastic bag tightly with the cable ties
provided.
– Remove the adhesive label next to the vacuum compensa-
tion hole and use it to seal the hole.
– Carefully take the sealed safety filter bag out of the
container (1) without damaging it. When doing so, make
sure that the safety filter bag does not scrape against the
connection flange or other sharp objects.
– Wipe the container (1) from time to time using a non-ab-
rasive off-the-shelf cleaning product and leave it to dry.
Fitting the rubber lip (wet extraction) (see
figure E)
Note: The requirements for the degree of penetration (dust
class H) have only been verified for dry extraction.
– Use a suitable tool to lift the brush inserts (31) out of the
floor nozzle (32).
– Place the rubber lips (30) in the floor nozzle (32).
Note: The textured side of the rubber lips must be facing
outwards.
Attaching the L-Boxx (see figure F)
– Click the L-Boxx onto the adapters (11).
You can attach an L-Boxx to the top part of the dust extractor
for transporting the extractor and to provide space-saving
storage for extractor accessories and/or the power tool.
Do not carry the dust extractor by the carrying handle
u
of the attached L-Boxx. The dust extractor is too heavy
for the carrying handle of the L-Boxx. There is a risk of in-
jury and damage if you do this.
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 lockable
castors on the dust extractor are blocked to prevent the dust
extractor from rolling away unintentionally. Test the correct
functioning of the castors on the relevant surface before op-
eration.
Start-up
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.
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 < 0.1 mg/m
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 (25) from the top part of the dust ex-
tractor (12).
Dry vacuuming
Vacuuming up dust deposits
– Adjust the volume flow controller (6) to suit the hose dia-
meter used.
– To switch on the dust extractor, set the
mode selector switch (7) to the "extraction"
symbol.
– To switch off the dust extractor, set the
mode selector switch (7) to the "switch off"
symbol.
The dust extractor is fitted with airflow monitoring. In the
"extraction" operating mode, the volume flow monitoring is
fixed to a value of 20 m/s, irrespective of the setting of the
volume flow controller (6).
If the value falls below this, e.g. due to accumulated dirt in
the vacuum hose, a full safety filter bag or a clogged flat-
pleated filter, an audible alarm signal will sound. In this case,
switch off the dust extractor and check it as described in the
"Rectifying faults" section.
Extracting dust that accumulates from working power
tools (see figure G)
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 (5), which can be used to connect an external
power tool. Observe the maximum permitted load of the
connected power tool.
In order for sufficient dust transport to be ensured at the ex-
traction point, the volume flow must not fall below the min-
imum specified for the connected power tool.

– Adjust the volume flow controller (6) to suit the hose dia-
meter used.
– Fit the dust extraction adapter (23).
– Insert the dust extraction adapter (23) into the 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
