Operation
Remove the battery before cleaning or performing
u
maintenance on the dust extractor, making tool ad-
justments, changing accessories or placing the dust
extractor in storage. This safety measure prevents the
dust extractor from being started accidentally.
Ensure that the work area is clean and tidy to minim-
u
ise the risk of tripping.
Starting Operation
The dust extractor must not be used without a filter.
u
Do not use damaged filters (e.g. no cracks, small
u
holes, etc.). Replace any damaged filters immedi-
ately.
Before extraction, ensure that the filter unit is se-
u
curely fitted.
Before extraction, ensure that the battery compart-
u
ment cover is securely closed.
Please inform yourself about the applicable regula-
u
tions/laws on how to handle harmful types of dust in
your country.
Only vacuum rock dust with the power tool and dust
u
extraction system combination explicitly identified,
for which it has been proven that the legal thresholds
are not exceeded. You can find this evidence at
http://www.bosch-professional.com/dust.
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 (13) from the vacuum hose
bracket (27).
Switching On and Off
To switch on the dust extractor, briefly press the on/off
button (3).
To switch off the dust extractor, press the on/off button (3)
again.
For safety reasons, the dust extractor does not switch on if
the on/off button (3) is held down for longer than five
seconds.
Dry Vacuuming
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.
– Fit the dust extraction adapter (14) or the curved
nozzle (15) (see "Fitting the extraction adapter or curved
nozzle (see figure D)", page 11).
– Insert the extraction adapter (14) or the curved
nozzle (15) into the power tool's dust extraction outlet.
Only when using the dust extraction adapter (14):
Note: When working with power tools that have a low air
feed into the vacuum hose (e.g. jigsaws, sanders, etc.), the
1 609 92A 6PF | (26.07.2021)
false air intake (32) of the dust extraction adapter (14) must
be opened. This will improve the total output of the dust ex-
tractor and the power tool. To do this, turn the ring above
the false air intake (32) until the opening is at its maximum
size.
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, 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.
Before wet vacuuming:
– Empty the container (1).
– Clean the filter (33) and fit it back into the dust ex-
tractor (see "Cleaning/replacing filters (see figures I1–
I2)", page 13).
The dust extractor is equipped with a float (34). Extraction
is stopped when the maximum filling level is reached.
After wet vacuuming, always:
– Empty the container (1).
– Empty the water from the filter (33).
To prevent mould growth after wet vacuuming:
– Remove the dust extractor lid (5) and leave it to dry thor-
oughly.
– Remove the filter (33) and also leave this to dry thor-
oughly (see "Cleaning/replacing filters (see figures I1–
I2)", page 13).
Maintenance and Servicing
Maintenance and Cleaning
Remove the battery before cleaning or performing
u
maintenance on the dust extractor, making tool ad-
justments, changing accessories or placing the dust
extractor in storage. This safety measure prevents the
dust extractor from being started accidentally.
To ensure safe and efficient operation, always keep
u
the dust extractor and the ventilation slots clean.
For the user to carry out maintenance, the dust extractor
needs to be disassembled, cleaned and maintained as far as
this is possible without endangering maintenance personnel
or other persons. Before disassembly, the dust extractor
should be cleaned to prevent any potential hazards. The
room/enclosure in which the dust extractor is disassembled
should be well ventilated. Wear personal protective equip-
ment while carrying out maintenance. After completing
maintenance, the maintenance area should be cleaned.
An inspection regarding the dust extraction capability must
be carried out at least once a year by the manufacturer or
someone who has been trained, e.g. to check for filter dam-
age, that the dust extractor is tight and that the control unit
is functioning correctly.
