– Pull the dump hose (23) from its holder and drain off the
waste water through the dump hose.
– To transport the dust extractor, screw the sealing plug (2)
onto the hose adapter (3).
– Empty the container (1).
To prevent mould growth after wet extraction:
– Remove the flat-pleated filter (30) and leave this to dry
thoroughly.
– Remove the top part of the dust extractor (13), open the
filter cover (39) and leave both elements to dry thor-
oughly.
Automatic filter cleaning (see figure I)
When automatic filter cleaning (AFC) is active, the flat-
pleated filter (30) 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.
In order to achieve an optimum filter service life, deactivate
the automatic filter cleaning function only in exceptional
cases, e.g. when vacuuming pure liquids or using a paper fil-
ter bag.
A flat-pleated filter with surface dirt is still fully functional. It
is not necessary to clean the flat-pleated filter manually by
shaking or blowing it out; this may even damage the filter.
Note: The automatic filter cleaning function is switched on
by default when the dust extractor leaves the factory.
It is only possible to switch the automatic filter function on or
off when the tool is switched on.
– Deactivating AFC
Press the AFC button (9).
The control LED (38) will go out.
– Activating AFC
Press the AFC button (9).
The control LED (38) will light up green.

Maintenance and service

Maintenance and cleaning

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.
To ensure safe and efficient operation, always keep
u
the dust extractor and the ventilation slots clean.
Wear a dust mask when servicing and cleaning the va-
u
cuum cleaner.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.

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 in which the dust extractor is disassembled should be
well ventilated. Wear personal protective equipment 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 vacuum cleaner is tight and that the control unit
is functioning correctly.
Class M dust extractors that have been in dirty environments
should have their exteriors, as well as all their components,
cleaned or treated with sealant. When performing mainten-
ance and repair work, all dirty parts that cannot be cleaned
satisfactorily must be disposed of. Such parts must be dis-
posed of in impermeable bags in accordance with the valid
provisions for disposing of such waste.
Removing/changing the flat-pleated filter (see figures
J1–J2)
Suction power is dependent on the condition of the filter.
Therefore, the filter should be cleaned regularly.
If the flat-pleated filter (30) becomes damaged, replace it
immediately.
– Pull on the closing flap (20) and open the filter cover
(39).
– Hold the flat-pleated filter (30) by the supports and take
it out from above.
– Use a damp cloth to remove any dust and dirt that ac-
crues around the closing edge of the filter cover (39)
when removing the flat-pleated filter (30).
PES and PTFE flat-pleated filters can be rinsed out under
running water.
– Insert the cleaned (or a new) flat-pleated filter (30), en-
suring that it is positioned correctly and securely.
– Close the filter cover (39) again (must audibly click into
place).
Cleaning the container
– Wipe the container (1) from time to time using a non-ab-
rasive off-the-shelf cleaning product and leave it to dry.
Cleaning the fill level sensors (see figure K)
Make sure that the fill level sensors are cleaned (40) occa-
sionally.
– Open the catches (15) and remove the top part of the
dust extractor (13).
– Clean the fill level sensors (40) using a soft cloth.
– Put the top part of the vacuum cleaner (13) on and close
the catches (15).
