For dry vacuuming operation, a dust bag 11 should be insert-
ed. When operating with a dust bag 11, the folded filter 12
clogs slower, the vacuuming performance is kept up longer
and the disposal of dust becomes easier.
Mounting the Vacuum Hose (see figure A)
– Mount the vacuum hose 8 onto the hose connection piece
7 and turn it in clockwise direction to the stop.
– Insert the extension tubes firmly into each other.
Note: Bosch recommends using static-discharging hoses
with a hose Ø of 19 or 35 mm.
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.
Switch the vacuum cleaner off immedi-
WARNING
ately as soon as foam or water comes
out, and empty the container. Otherwise, the vacuum clean-
er can become damaged.
 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 > 1 mg/m
The vacuum cleaner may generally not be used in rooms
where the danger of an explosion exists.

Operation with remote automatic switching
Switching On and Off
– To start the operation of the vac, set the mode selector
switch 4 to on.
To save energy, only switch the vacuum cleaner on when
using it.
– To switch off the vac, set the mode selector switch 4 to
off.
Operation with remote automatic switching (see figure B)
A socket outlet with earthing contact 5 is integrated in the
vacuum cleaner, which allows for connection of an external
power tool. The vacuum cleaner is automatically put into op-
eration via the power tool. Observe the maximal allowable
load of the connected power tool.
Bosch Power Tools
– Set the mode selector switch 4 to the operation with re-
mote automatic switching symbol.
For connecting power tools, various hose systems are availa-
ble as accessories.
– To start the operation of the vac, switch on the power tool
connected to the socket 5. The vacuum cleaner starts au-
tomatically.
– To switch off the vac, switch off the power tool. The vacu-
um cleaner switches off automatically approx. 6 seconds
later.
Electromagnetic filter cleaning (SFC)
The machine is equipped with an electromagnetic filter clean-
ing system, which removes dust adhering to the folded filter
12.
The filter cleaning system must be actuated at the latest when
the vacuuming performance is no longer sufficient.
– Set the mode selector switch 4 to the symbol electromag-
netic filter cleaning. A possibly connected power tool
must be switched off.
The machine vibrates for approx. 10 seconds and switches
off automatically.
– Wait shortly before restarting the vacuuming operation so
that the dust can settle in the container.
The filter cleaning frequency depends on the type and amount
of dust. With regular usage, the maximum vacuuming perfor-
mance is maintained longer.

Wet Vacuuming

3
 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 L) have only been proven for dry vacuuming.
Before wet vacuuming, the dust bag 11 must be removed and
the container 9 must be emptied.
– The machine is equipped with level sensors 14. The vac
switches off when the maximum filling height is reached.
Set the mode selector switch 4 to off.
– After vacuuming, remove the folded filter 12 in order to
avoid mildew, and allow it to dry thoroughly, or remove the
vacuum lid 3 and allow it to dry.
