Assembly
Before any work on the vacuum cleaner itself, pull the mains plug.
Mounting the Handle
The vacuum cleaner cart is designed in such a manner, that the vacuum cleaner
can be pushed easier with the push handle 14. Always grasp the push handle
14 with both hands when pushing the vac.
Insert the push handle 14 into the 2 openings of the container 9.
Push the clamps 13 through the corresponding holes of the push handle
14 and then lock the clamps 13.
The casters are equipped with brakes 10. To actuate the castor 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 toward 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. Reattach the vacuum lid 3.
- Lock the latches 11.
For dry vacuuming operation, a dust bag 16 should be inserted. 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 power 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.

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 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 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
available as accessories.
To start the operation of the vac, switch on the power tool connected to the
socket 5. The vacuum cleaner starts automatically.
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 cleaning 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 electromagnetic 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 automatically 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 performance is maintained longer.
Wet Vacuuming
- Do not vacuum inflammable or explosive fluids; for example, 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 water mixtures.
- Before any work on the vacuum cleaner itself, pull the mains plug.
Note: Before wet vacuuming, the dust bag 16 must be removed 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.
Application Possibilities
The vacuum cleaner is suitable for vacuuming and extracting the following materials:
- Fine dusts below the general dust limit value of 3 mg/m3
- Dusts of mineral materials with aluminium hydroxide
- Graphite dusts
- Aluminium dusts
- Paper dusts
- Soot dusts
- Powder-paint dusts
- Polyurethane dusts
- GFRP dusts based on epoxy resin, see manufacturer’s data sheet on safety
- CFP dusts based on epoxy resin, see manufacturer’s data sheet on safety
The vacuum cleaner may generally not be used in rooms where the danger of an explosion exists.
Maintenance and Service
Maintenance and Cleaning
-
Before any work on the vacuum cleaner itself, pull the mains plug.
-
For safe and proper working, always keep the vacuum cleaner and ventilation slots clean.
If the replacement of the supply cord is necessary, this has to be done by
Bosch or an authorized Bosch service agent in order to avoid a safety hazard.
