Extraction of dusts resulting from running power tools
(see figure G)
 An adequate ventilation rate (L) must be provided for
when the outgoing air is circulated. Observe the re-
spective national regulations.
A socket outlet with earthing contact 5 is integrated in the
vacuum cleaner. An external power tool can be connected
there. Observe the maximal allowable load of the connected
power tool.
To ensure sufficient dust transport at the vacuum location,
the minimum airflow for the power tool connected must not
be fallen below.
Hose Diameter
35 mm
22 mm
15 mm
– Set the airflow regulator 6 to the hose diameter being
used.
– Mount the tool sleeve 22 (see "Mounting the Tool Sleeve",
page 19).
– Insert the tool sleeve 22 into the vacuum connection of the
power tool.
– To start the vacuum cleaner's automatic
Start/Stop feature, set the mode selector
switch 7 to the "Automatic Start/Stop" sym-
bol.
In this operating mode, the airflow is electronically moni-
tored according to the setting of the airflow regulator 6.
Sufficient dust transport is ensured when the setting is
correctly selected.
– To start the operation of the vac, switch on the power tool
connected to the socket 5. The vacuum cleaner starts au-
tomatically.
– Switch the power tool off to end the vacuuming.
The delayed action shutdown of the Automatic Start/Stop
continues to run for up to 15 seconds in order to extract re-
sidual dust from the vacuum hose.
– To switch the vacuum cleaner off, set the mode
selector switch 7 to the "Off" symbol.
When the alarm sounds, the vacuum cleaner must be checked
as described under "Correction of Malfunctions".

Wet Vacuuming

 Do not vacuum inflammable or explosive fluids; for ex-
ample, benzene, oil, alcohol, solvents. Do not vacuum
hot or burning dust. Do not operate the machine in
rooms where the danger of an explosion exists. The
dusts, vapours or fluids can ignite or explode.
 The vacuum cleaner may not be used as a water pump.
The vacuum cleaner is intended for vacuuming air and wa-
ter mixtures.
 Before any work on the vacuum cleaner itself, pull the
mains plug.
Note: The requirements for the ingress degree (dust category
M) have only been proven for dry vacuuming.
Bosch Power Tools
– Remove the disposal bag 25 or the dust bag and empty the
container 1 before wet vacuuming.
Note: For easier disposal when vacuuming liquid-solid mix-
tures, use a wet filter bag (accessory), which separates liq-
uids from solids.
– Mount the rubber lips into the floor nozzle (see "Inserting
the Rubber Lip", page 20).
– Switch the automatic filter cleaning (AFC) off (see "Deacti-
vating the AFC", page 21).
The vacuum cleaner is equipped with filling-level sensors 37.
When the maximum filling height is reached, the vacuum
cleaner switches off. Set the mode selector switch 7 to the
"off" symbol.
Airflow Setting Value
Note: When vacuuming non-conductive liquids (e. g. drilling
3
57.9 m /h
emulsion, oil and grease), the vacuum cleaner is not switched
3
41.2 m /h
off when the container is full. The level must be monitored
3
12.7 m /h continuously and the container emptied in time.
When the alarm sounds while wet vacuuming, the operational
safety of the VAC is not impaired. No measures are required to
correct the malfunction.
– For transport of the vacuum cleaner, screw the plug cap 2
onto the hose connection piece 3.
To prevent the formation of mould after wet vacuuming:
– Take out the flat-fold filter 26 and allow it to dry well.
– Remove the vacuum cleaner lid 12 open the filter cover 36
and allow both components to dry thoroughly.

Filter Cleaning

Automatic filter cleaning (see figure H)
In automatic filter cleaning mode (AFC = Automatic Filter
Cleaning), the flat-fold filter 26 is cleaned every 15 seconds
by means of air blasts (pulsating noise).
The filter cleaning system must be actuated at the latest when
the vacuuming performance is no longer sufficient.
Regular use of the filter cleaning feature increases the tool life
of the filter.
To achieve ideal filter tool life, deactivate the automatic filter
cleaning in exceptional cases, e. g., when vacuuming pure liq-
uids or when working with a paper filter bag.
A flat-fold filter contaminated only on the surface is fully func-
tional. Manual cleaning of the flat-fold filter by striking/tap-
ping against it or blowing it out is not necessary, and can even
damage the filter.
Note: The automatic filter cleaning is factory-set.
Switching the automatic filter cleaning on/off is only possible,
when the VAC is running.
– Deactivating the AFC
Actuate the AFC button 9.
The signalling LED 35 goes out.
– Activating the AFC
Actuate the AFC button 9.
