  • WARNING: Do not vacuum materials that are harmful to one’s health, e.g. dust from beech or oak wood, masonry dust, asbestos. These materials are considered carcinogenic.
    WARNING: Use the vacuum cleaner only when you fully understand and can perform all functions without limitation, or have received appropriate instructions. A thorough introduction reduces operating errors and injuries.

  • Children or persons that, owing to their physical, sensory or mental limitations or to their lack of experience or knowledge, are not capable of securely operating the vacuum cleaner, may only use this vacuum cleaner under supervision or after having been instructed by a responsible person. Otherwise, there is danger of operating errors and injuries.
    WARNING: The vacuum cleaner is suitable for vacuuming dry materials and, by taking suitable measures, also for vacuuming liquids. The penetration of liquids increases the risk of an electric shock.

  • 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.

  • WARNING: Use the socket only for the purposes specified in of the operating instructions.

  • WARNING:  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.

  • WARNING: The vacuum cleaner may only be used and stored indoors. The penetration of rain or moisture into the vacuum cleaner lid increases the risk of an electric shock.

  • WARNING: Clean the filling-level sensors for liquids at regular intervals, and check them for damage. Otherwise, their function can be impaired.

  • When operating the vacuum cleaner in damp environments, use a residual current device (RCD). Using a residual current device (RCD) reduces the risk of an electric shock.

  • Connect the vacuum cleaner to a properly earthed mains supply. The socket outlet and the extension cable must have an operative protective conductor.

  • Before each use, check the vacuum cleaner, cable and plug. Do not use the vacuum cleaner when defects are detected. Do not open the vacuum cleaner yourself and have it repaired only by qualified personnel using original spare parts. Damaged vacuum cleaner, cables and plugs increase the risk of an electric shock.

  • Do not drive over, crush or stretch the cable. Do not pull the cable to unplug the plug from the socket outlet or to move the vacuum cleaner. Damaged cables increase the risk of an electric shock.

  • During work breaks, when not in use or when working on the machine (e. g. changing tool inserts, repairs, cleaning, adjustments), pull the mains plug. This safety measure prevents accidental starting of the vacuum cleaner.

  • Provide for good ventilation at the working place.

  • Supervise children. This will ensure that children do not play with the vacuum cleaner.

  • Have the vacuum cleaner repaired only through qualified specialists and only using original spare parts. This ensures that the safety of your vacuum cleaner is maintained.

  • Before restarting, check the proper condition of the vacuum hose. When doing this, leave the vacuum hose mounted to the vacuum cleaner to avoid dust from coming out. Otherwise, you could possible inhale dust.

  • Do not use the vacuum cleaner as a seat. The vacuum cleaner could become damaged.

  • Use the mains cable and the vacuum hose carefully. Other persons could be harmed.

  • Do not clean the vacuum cleaner with a water jet pointed directly at it. The penetration of water into the vacuum cleaner lid increases the risk of an electric shock.

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)
Dust Bag Installation

  • 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.

Symbols on the Mode Selector Switch

  • on: Switching On

  • off: Switching Off

  • Electromagnetic filter cleaning (Remote automatic switching and  automatic filter cleaning).
    Symbol

  • 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.
Operation Instructions
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.
If the vacuum cleaner should fail despite the care taken in manufacturing and testing procedures, repair should be carried out by an after sales service centre for Bosch power tools.
In all correspondence and spare parts order, please always include the 10 digit article number given on the type plate of the machine.
