Dry Vacuuming; Wet Vacuuming - Bosch GAS 35 L AFC Professional Notice Originale

20 | English
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 (21) from the top part of the dust ex-
tractor (10).

Dry vacuuming

Vacuuming up dust deposits
– To switch on the dust extractor, set the
mode selector switch (6) to the "extraction"
symbol.
– To switch off the dust extractor, set the
mode selector switch (6) to the "switch off"
symbol.
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 (4), which can be used to connect an external
power tool. Observe the maximum permitted load of the
connected power tool.
– Fit the dust extraction adapter (20).
– Insert the dust extraction adapter (20) 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 (32) of the dust extraction adapter (20) 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 (6) to the "auto-
matic start/stop" symbol.
– To start the dust extractor, switch on the power tool
connected to the plug socket (4). 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 15 seconds longer in order to extract the remaining
dust from the vacuum hose.

off" symbol.

Wet vacuuming

3
Do not use the vacuum cleaner to vacuum combustible
u
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.
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: The requirements for the degree of penetration (dust
class L) have only been verified for dry vacuuming.
Steps to Take before Wet Vacuuming
– Remove the disposal bag (23) or dust bag if necessary.
Note: Use a wet filter bag (accessory), which separates li-
quid from solids, to make disposal easier when vacuuming
water-solid mixtures.
– Place the rubber lip (26) into the floor nozzle (28).
– Switch off the automatic filter cleaning (AFC).
Vacuuming up liquids
– To switch on the dust extractor, set the mode selector
switch (6) to the "extraction" symbol.
The dust extractor is equipped with fill level sensors (35).
The dust extractor shuts down if the maximum fill level has
been reached. Set the mode selector switch (6) to the
"switch off" symbol.
Note: When extracting non-conductive liquids (e.g. drilling
emulsion), the dust extractor will not switch off when the
container is full. The fill level must be constantly monitored
and the container emptied in good time.
– To switch off the dust extractor, set the mode selector
switch (6) to the "switch off" symbol.
– Empty the container (1).
To prevent mould growth after wet extraction:
– Remove the flat-pleated filter (24) and leave this to dry
thoroughly.
– Remove the top part of the dust extractor (10), open the
filter cover (34) and leave both elements to dry thor-
oughly.
Automatic filter cleaning (see figure H)
When automatic filter cleaning (AFC) is active, the flat-
pleated filter (24) is cleaned every 15 seconds using blasts
of air (pulsating noise).
The filter cleaning function should be used regularly, and at
the very latest when the suction power is no longer suffi-
cient.
Regular use of the filter cleaning function will increase the
service life of the filter.
