Operation
Starting Operation
 Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the vacuum cleaner. Equipment marked
with 230 V can also be operated with 220 V.
 Please inform yourself about the valid regula-
tions/laws for your country concerning the handling of
materials that are hazardous to one's health.
The vacuum cleaner is suitable for vacuuming and extracting
the following materials:
– Dusts with an exposition limit value ≥ 0.1 mg/m
The vacuum cleaner may generally not be used in rooms
where the danger of an explosion exists.
To save energy, only switch the vacuum cleaner on when us-
ing it.
To ensure optimal vacuuming performance, always complete-
ly unwind the vacuum hose 24 from the vacuum cleaner lid
12.
Dry Vacuuming
Vacuuming of deposited dusts
– Set the airflow regulator 6 to the hose diameter being
used.
– To switch the vacuum cleaner on, set the mode
selector switch 7 to the "vacuuming" symbol.
– To switch the vacuum cleaner off, set the mode
selector switch 7 to the "Off" symbol.
The vacuum cleaner is fitted with airflow monitoring. In the
"vacuuming" mode, the airflow monitoring is fixed on a value of
20 m/s, irrespective of the setting of the airflow regulator 6.
If the value falls below this, e.g. due to accumulated dirt in the
suction hose, a full dust bag or a clogged flat-fold filter, an audi-
ble alarm signal will sound.In this case, switch off the vacuum
cleaner and check it as stated in the section "Correction of Mal-
functions".
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.

Bosch Power Tools
– Set the airflow regulator 6 to the hose diameter being
used.
– Mount the tool sleeve 22 (see "Mounting the Tool Sleeve",
page 20).
– 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.
– 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 22).
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.
Note: When vacuuming non-conductive liquids (e. g. drilling

emulsion, oil and grease), the vacuum cleaner is not switched
