– To switch off the dust extractor, set the mode selector switch (5) to the “switch off” symbol.

Extracting dust that accumulates from working power tools (see figure H)

• There must be a sufficient air exchange rate (L) in the room when the exhaust air comes back into the room. Be aware of the corresponding national regulations.
  The dust extractor has an electric socket with a protective earth contact (3), which can be used to connect an external power tool. Observe the maximum permitted load of the connected power tool.
• Fit the extraction adapter (19) Fitting the dust extraction adapter.
• Insert the extraction adapter (19) into the dust extraction outlet of the power tool.
  Note: When working with power tools that have a low air feed into the vacuum hose (e.g. jigsaws, sanders, etc.), the false air intake (32) of the extraction adapter (19) must be opened. Only then can the semi-automatic filter cleaning (SFC+) system work without any problems. To do this, turn the ring above the false air intake (32) until the opening is at its maximum size.
• To activate the automatic start/stop function of the dust extractor set the mode selector switch (5) to the “automatic start/stop” symbol.
• To activate the dust extractor, switch on the power tool that is plugged into the electric socket (3). The dust extractor will start automatically.
• To stop dust extraction, switch the power tool off. The automatic start/stop run-on function will run up to 15 seconds longer in order to extract the remaining
  dust from the vacuum hose.
• To switch off the dust extractor, set the mode selector switch (5) to the “switch off” symbol.

Wet vacuuming

• Do not use the vacuum cleaner to vacuum combustible or explosive liquids, such as petrol, oil, alcohol, or solvents. Do not vacuum hot, burning, or explosive dust. Do not operate the vacuum cleaner in areas subject to explosion hazards. Dust, vapors, and liquids can ignite or explode.
• The vacuum cleaner must not be used as a water pump. The vacuum cleaner is designed for vacuuming air and vacuuming water mixtures.
  Note: The requirements for the degree of penetration (dust class L) have only been verified for dry vacuuming. Steps to Take before Wet Vacuuming
• Remove the disposal bag (23) or dust bag if necessary.
  Note: Use a wet filter bag (accessory), which separates liquid from solids, to make disposal easier when vacuuming water-solid mixtures.
• Place the rubber lip (26) into the floor nozzle (28). (see ” Fitting the rubber lip (wet vacuuming) (see figure F)”, page 20)
• Switch off semi-automatic filter cleaning (SFC+) (see “Semi-automatic filter cleaning (see figure I)”, page 21).

Vacuuming up liquids

• To switch on the dust extractor, set the mode selector switch (5) to the “extraction” symbol. The dust extractor is equipped with fill-level sensors (35). The dust extractor shuts down if the maximum fill level has been reached. Set the mode selector switch (5) to the “switch off” symbol.
  Note: When extracting non-conductive liquids (e.g. drilling emulsion, oils, and fats), the dust extractor will not switch off when the container is full. The fill level must be constantly monitored and the container emptied in good time.
• To switch off the dust extractor, set the mode selector switch (5) to the “switch off” symbol.
• Empty the container (1).
  To prevent mold growth after wet vacuuming:
• Remove the flat-pleated filter (24) and leave this to dry thoroughly.
• Remove the top part of the dust extractor (8), open the filter cover (34), and leave both elements to dry thoroughly.

Semi-automatic filter cleaning (see figure I)
The filter cleaning function should be used regularly, and at the very latest when the suction power is no longer sufficient.
How often filter cleaning needs to be carried out will depend on the type and quantity of dust that has been extracted. With regular use, the maximum conveying capacity will be
maintained for longer. During semi-automatic filter cleaning (SFC+), the airflow is reversed to clean deposited dust from the flaps of the flat pleated filter.
A pleated filter with surface dirt is still fully functional. It is not necessary to clean the flat-pleated filter manually by shaking or blowing it out; this may even damage the filter.
Note: Semi-automatic filter cleaning is activated at the factory (SFC+ switch (18) in the position I).
– Actuating SFC+ filter cleaning
Use the palm of your hand to close the opening in the nozzle or vacuum hose.  Or, if the SFC+ module (20) is fitted: Push the actuator (33) down for approximately 10 seconds.
– Deactivating SFC+ Push the SFC+ switch (18) forwards (position 0).
– Activating SFC+ Push the SFC+ switch (18) backwards (position I).

Maintenance and service

Maintenance and cleaning

• To ensure safe and efficient operation, always keep the dust extractor and the ventilation slots clean.
• Wear a dust mask when servicing and cleaning the vacuum cleaner.

In order to avoid safety hazards, if the power supply cord needs to be replaced, this must be done by Bosch or by an after-sales service center that is authorized to repair Bosch power tools. For the user to carry out maintenance, the vacuum cleaner needs to be disassembled, cleaned, and maintained as far as this is possible without endangering maintenance personnel or other persons. Before disassembly, the vacuum cleaner should be cleaned to prevent any potential hazards. The room in which the vacuum cleaner is disassembled should be well ventilated. Wear personal protective equipment while carrying out maintenance. After completing maintenance, the maintenance area should be cleaned. An inspection regarding the dust extraction capability must be carried out at least once a year by the manufacturer or someone who has been trained, e.g. to check for filter damage, that the vacuum cleaner is tight and that the control unit is functioning correctly. Class L vacuum cleaners that were located in dirty environments should have their exteriors, as well as all their components, cleaned or treated with sealant. When performing maintenance and repair work, all dirty parts that cannot be cleaned satisfactorily must be disposed of. Such parts must be disposed of in impermeable bags in accordance with the valid provisions for disposing of such waste.

Removing/changing the flat-pleated filter (see figures J1–J2) Suction power is dependent on the condition of the filter. Therefore, the filter should be cleaned regularly. If the flat-pleated filter (24) becomes damaged, replace it immediately.

• Pull on the closing flap (14) and open the filter cover (34).
• Hold the flat-pleated filter (24) by the supports and take it out from above.
• Use a damp cloth to remove any dust and dirt that accrues around the closing edge of the filter cover (34) when removing the flat-pleated filter (24). PES and PTFE flat-pleated filters can be rinsed out under running water.
• Insert the cleaned (or a new) flat-pleated filter (24), ensuring that it is positioned correctly and securely.
• Close the filter cover (34) again (must audibly click into place). Cleaning the container
• Wipe the container (1) from time to time using a non-abrasive off-the-shelf cleaning product and leave it to dry. Cleaning the fill level sensors (see figure K) Make sure that the fill level sensors are cleaned (35) occasionally.
