Assembly

To assemble the vacuum cleaner, follow these steps:

• Pull the plug out of the socket before cleaning or performing maintenance on the vacuum cleaner, making tool adjustments, changing accessories or putting away the vacuum cleaner. This safety measure prevents the vacuum cleaner from being started accidentally. Fitting the vacuuming accessories (see figure A) The vacuum hose (17) is equipped with a clip system which can be used to connect vacuuming accessories (dust extraction adapter (18), curved nozzle (19)).

• Fitting the nozzles and tubes

  • Push the curved nozzle (19) onto the vacuum hose (17) until you hear both snap fasteners (24) on the vacuum hose engage.
  • Then attach the required extraction accessory (coarse dirt nozzle, crevice nozzle, suction tube, etc.) firmly to the curved nozzle (19).
  • To remove the adapter, press the snap fasteners (24) inwards and pull apart the components.

• Fitting the dust extraction adapter

  • Push the dust extraction adapter (18) onto the vacuum hose (17) until you hear both snap fasteners (24) on the vacuum hose engage.
  • To remove the adapter, press the snap fasteners (24) inwards and pull apart the components.

• Fitting the holder for the vacuum hose (see figure B)

  • Slide the holder (14) for the vacuum hose (17) firmly into the adapter (25) provided for it from above until it clicks into place.

• Fitting the vacuum hose (see figure C)

  • Insert the vacuum hose (17) firmly into the hose adapter (2).
    Note : The friction generated by the dust in the vacuum hose and accessory during extraction causes an electrostatic charge that the user may experience as static discharge (depending on environmental factors and their physiological state). Bosch generally recommends using an anti-static vacuum hose (accessory) to vacuum up fine dust and dry materials.

  • Attach the suction hose to the vacuum cleaner’s suction inlet (see image C).

Inserting/removing the disposal bag or dust bag (dry vacuuming) (see figures D1–D2)

Test the correct functioning of the wheels (8) and castors (9) on the relevant surface before operation.

Start-up

• Pay attention to the mains voltage. The voltage of the power source must correspond with the information on the type plate of the dust extractor. Dust extractors marked with 230 V can also be operated with 220 V.
• Make sure you inform yourself about the applicable regulations/laws on how to handle harmful types of dust in your country.

The dust extractor may be used for vacuuming and extracting the following materials:

• Dusts with an exposure limit of > 1 mg/m3
• Products that are only sold in AUS and NZ: Use a residual current device (RCD) with a nominal residual current of 30 mA or less. The dust extractor must categorically not be used in potentially explosive areas.
• To ensure optimum suction power, you must always fully unwind the vacuum hose (17) from the top part of the dust extractor (6).

Dry vacuuming
Vacuuming up Dust Deposits

• To switch on the dust extractor, briefly press the on/off button (4).
• To switch off the dust extractor, press the on/off button (4) again.

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

• 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 a plug socket with a protective earth contact (3) that can be used to connect an external power tool. Observe the maximum permitted connected load of the connected power tool.

• Fit the extraction adapter (18) (see “Fitting the dust extraction adapter”, page 16).

• Insert the dust extraction adapter (18) into the 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 (26) of the dust extraction adapter (18) must be opened. Only then can the semi-automatic filter cleaning (SFC) work without any problems. To do this, turn the ring above the false air intake (26) until the opening is at its maximum size.

• To activate the automatic start/stop function of the dust extractor, briefly press the on/off button (4).

• To start the dust extractor, switch on the power tool connected to the plug 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 for up to 15 seconds longer in order to extract the remaining dust from the vacuum hose.

• To switch off the dust extractor, press the on/off button (4).

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, vapours 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.
  Steps to Take before Wet Vacuuming

• Open the catches (7) and remove the top part of the vacuum cleaner (6).

• Remove the disposal bag (20) or dust bag if necessary.

• Empty the container (1) if necessary.

• Put the top part of the vacuum cleaner (6) on and close the catches (7).

Vacuuming up liquids

• Switch on the dust extractor. The dust extractor is equipped with a float. Extraction is stopped when the maximum filling level is reached.
• Switch off the dust extractor.
• Empty the container (1). To prevent mould growth after wet extraction:
• Remove the top part of the dust extractor (6), then remove the pleated filter (28) and leave everything to dry thoroughly.

Semi-automatic filter cleaning (see figure F)
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 vacuumed. With regular use, the maximum conveying capacity will be maintained for longer. During semi-automatic filter cleaning (SFC), the air flow is reversed to clean deposited dust from the flaps of the 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.

Triggering the SFC Filter Cleaning

• Use the palm of your hand to close the nozzle or vacuum hose opening.
• Press the SFC switch (11) three times.

Maintenance and Cleaning

Follow these instructions to maintain and clean the Bosch GAS 20 L SFC Professional vacuum cleaner:
