The casters are equipped with brakes 10. To actuate the cas-
tor brake 10 press the lever downwards.
Replacing/Inserting the Dust Bag (see figure A)
– Unlock the latches 11 and remove the vacuum lid 3.
– Pull off the full dust bag 16 from the connection flange to-
ward the rear. Close the opening of the dust bag by folding
down the lid. Remove the closed dust bag from the vacuum
cleaner.
– Slide the new dust bag 16 over the connection flange of the
vacuum cleaner. Make sure that the full length of the dust
bag 16 faces against the inner wall of the container 9. Reat-
tach the vacuum lid 3.
– Lock the latches 11.
For dry vacuuming operation, a dust bag 16 should be insert-
ed. When operating with a dust bag 16, the folded filter 17
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 immediately as soon as
foam or water comes out, and empty the container.
Otherwise, the vacuum cleaner can become damaged.

Switching On and Off
To start the operation of the vac, set the mode selector
switch 4 to on.
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
Bosch Power Tools
operation via the power tool. Observe the maximal allowable
load of the connected power tool.
Set the mode selector switch 4 to the operation with remote
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 auto-
matically.
To switch off the vac, switch off the power tool. The vacuum
cleaner switches off automatically approx. 6 seconds later.
Electromagnetic filter cleaning
The machine is equipped with an electromagnetic filter clean-
ing system, which removes dust adhering to the folded filter
17.
The filter cleaning system must be actuated latest when the
vacuuming performance is no longer sufficient.
Set the mode selector switch 4 to the symbol electromagnet-
ic filter cleaning. A possibly connected power tool must be
switched off.
The machine vibrates for approx. 10 seconds and switches
off automatically.
When operating the vacuum cleaner in electromagnetic filter
cleaning mode, the vacuum cleaner checks the airflow. When
the airflow is too low due to a clogged/soiled folded filter and
the connected power tool is switched off since at least
10 seconds, the electromagnetic filter cleaning is automati-
cally started. The vacuum cleaner 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 per-
formance is maintained longer.

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: Before wet vacuuming, the dust bag 16 must be re-
moved and the container 9 must be emptied.
The machine is equipped with level sensors 19. 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 17 in order to avoid
mildew, and allow it to dry thoroughly, or remove the vacuum
lid 3 and allow it to dry.
