Dry Vacuuming; Wet Vacuuming - Bosch GAS 12-25 Notice Originale

Start-up
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 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).
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
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.

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).
Vacuuming up dust deposits (GAS 12-25)
– To switch on the vacuum cleaner, set the
on/off switch (1) to the "on" symbol.
– To switch off the vacuum cleaner, set the
on/off switch (1) to the "off" symbol.
Vacuuming up dust deposits (GAS 12-25 PL)
– To switch on the vacuum cleaner, set the
mode selector switch (1) to the "vacuuming"
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 (GAS 12-25 PL) (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 vacuum cleaner has an electric socket with
a protective earth contact (2) that can be used
to connect an external power tool. Observe the
maximum permitted load of the connected
power tool.
– Fit the dust extraction adapter (16) (see "Fitting the dust
extraction adapter (GAS 12-25 PL)", page 11).
– Insert the dust extraction adapter (16) into the dust ex-
traction 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
Bosch Power Tools
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 vacuum cleaner, set the
mode selector switch (1) to the "auto-
matic start/stop" symbol.
– To put the vacuum cleaner into operation, switch on
the power tool that is plugged into the electric socket
(2). The vacuum cleaner will start automatically.
– To stop dust extraction, switch the power tool off.
The automatic start/stop run-on function will run for up
to six seconds longer in order to extract the remaining
dust from the vacuum hose.
– To switch off the vacuum cleaner, set the
3
mode selector switch (1) to the "switch
off" symbol.

Wet vacuuming

Do not use the vacuum cleaner to vacuum combustible
u
or explosive liquids, such as petrol, oil, alcohol or
solvents. Do not vacuum hot or burning dust. Do not
operate the vacuum cleaner in areas subject to explo-
sion hazards. Dust, vapours and liquids can ignite or ex-
plode.
The vacuum cleaner must not be used as a water
u
pump. The vacuum cleaner is designed for vacuuming air
and vacuuming water mixtures.
Note: Make sure that both the pre-filter (22) and the main
filter (20) are removed from the vacuum cleaner when carry-
ing out wet vacuuming (see also figures D1 and E1).
Steps to Take Before Wet Vacuuming
– Open the catches (9) and remove the top part of the va-
cuum cleaner (10) (see figure C).
– Remove the pre-filter (22) from the container (7).
– Remove the plastic bag (19) or dust bag if necessary.
– Turn the filter holder (28) as far as possible in the direc-
tion of rotation
the main filter (20), out of the top part of the vacuum
cleaner (10).
– Place the wet filter (21) completely over the filter basket
(29).
– 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.
