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.
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.
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
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 (24) 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
"vacuuming" 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 dust bag or a clogged flat-pleated fil-
ter, an audible alarm signal will sound. In this case, switch off
the dust extractor and check it as described in the "Rectify-
ing 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 extraction adapter (22) (see "Fitting the dust ex-
traction adapter", page 21).
– Insert the extraction adapter (22) 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 (34) of the dust extraction adapter (22) must
3
be opened. This will ensure that the automatic filter cleaning
function works correctly.
To do this, turn the ring above the false air intake (34) until
the opening is at its maximum size.
– To activate the automatic start/stop
function of the dust extractor, set the op-
erating mode selector switch (7) to the
"automatic start/stop" symbol.
In this operating mode, the volume flow is
electronically monitored according to the
setting of the volume flow controller (6).
Sufficient dust transport is ensured when
the setting is correctly selected.
– To activate the dust extractor, switch on the power tool
that is plugged into the electric socket (5). The dust ex-
tractor will start automatically.
– To stop dust extraction, switch the power tool off.
The automatic start/stop run-on function will run for up
to 15 seconds longer in order to extract the remaining
dust from the vacuum hose.
– To switch off the dust extractor, set the
mode selector switch (7) to the "switch
off" symbol.
If the acoustic warning signal sounds, the dust extractor
must be checked as described in the "Rectifying faults" sec-
tion.
Wet vacuuming
Do not use the vacuum cleaner to vacuum combustible
u
or explosive liquids, such as petrol, oil, alcohol or
