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)
.
GAS 12-25 PL
:
The dust extractor may be used for vacuuming and extract-
ing the following materials:
– Dusts with an exposure limit of > 1 mg/m

u
Products that are only sold in AUS and NZ:
Use a resid-
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Dry vacuuming
Note:
When carrying out dry extraction, ensure that both the
pre-filter
(22)
and the main filter
(20)
are inserted into the
dust extractor.
Vacuuming up dust deposits (GAS 12-25)
– To

on/off switch
(1)
to the "on" symbol.
– To
switch off
the vacuum cleaner, set the
on/off switch

Extracting dust deposits (GAS 12-25 PL)
– 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"

Extracting dust that accumulates from working power
tools (GAS 12-25 PL) (see figure I)
u
There must be a sufficient air exchange rate (L) in the
room when the exhaust air comes back into the room.
Be aware of the corresponding national regulations.
The dust extractor has a plug socket with a pro-
tective 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.
–
GAS 12-25 PL
: Fit the extraction adapter
(16)
.
– Insert the dust extraction adapter
(16)
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
false air intake
(33)
of the dust extraction adapter
(16)
must
be opened. This will ensure that the semi-automatic filter
cleaning function works correctly.
To do this, turn the ring above the false air intake
(33)
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.
– To
start
the dust extractor, switch on the power tool
connected to the plug socket
(2)
. The dust extractor will
start automatically.
– To
stop
dust extraction
, switch the power tool off.
The automatic start/stop run-on function will run for up
to 6 seconds longer in order to extract the remaining
dust from the vacuum hose.
– To
switch off
the dust extractor, set the
mode selector switch
(1)
to the "switch
off" symbol.
Wet vacuuming
u
Do not use the vacuum cleaner to vacuum combustible
or explosive liquids, such as petrol, oil, alcohol or
solvents. Do not vacuum hot, burning or explosive
dust. Do not operate the vacuum cleaner in areas sub-
ject to explosion hazards.
Dust, vapours and liquids can
ignite or explode.
u
The vacuum cleaner must not be used as a water
pump.
The vacuum cleaner is designed for vacuuming air
and vacuuming water mixtures.
Note:
When wet vacuuming, ensure that the main filter
(20)
is removed from the vacuum cleaner.
Steps to Take Before Wet Vacuuming
– Open the catches
(9)
and remove the top part of the va-
cuum cleaner
(10)
(see figure
C
).
– Take the pre-filter
(22)
out of the container
(7)
by its
handle
(28)
.
– Remove the plastic bag
(19)
or dust bag if necessary.
– Turn the filter holder
(29)
as far as possible in the direc-
tion of rotation
and take the filter holder, together with
the main filter
(20)
, out of the top part of the vacuum
cleaner
(10)
.
– Insert the pre-filter
(22)
back in the container
(7)
, mak-
ing sure that the arrow is pointing towards the hose con-
nection piece
(3)
.
Ensure that the wet filter
(21)
lies completely over the fil-
ter basket
(30)
.
– Put the top part of the vacuum cleaner
(10)
on and close
the catches
(9)
.
– Place the rubber lip
(23)
in the floor nozzle
(25)
.
Vacuuming up liquids
– Switch the vacuum cleaner on (
GAS 12-25
: On/off switch
(1)
to "on";
GAS 12-25 PL
: Mode selector switch
(1)
to
the "vacuuming" symbol).
The dust extractor is equipped with a float. Extraction is
stopped when the maximum filling level is reached.
– Set the on/off switch
(1)
to "off" (
GAS 12-25
) or set the
mode selector switch
(1)
to the "switch off" symbol
(
GAS 12-25 PL
).
– Empty the container
(7)
.
