Pay attention to the mains voltage. The voltage of the power source must correspond with the data on the type plate of the vacuum cleaner.
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 (21) from the top part of the dust extractor (10).

Dry vacuuming

Vacuuming up dust deposits

To switch on the dust extractor, set the mode selector switch (6) to the “extraction” symbol.
To switch off the dust extractor, set the mode selector switch (6) to the “switch off” symbol.

Extracting dust that accumulates from working power tools

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 (4), which can be used to connect an external power tool. Observe the maximum permitted load of the connected power tool.
- Fit the dust extraction adapter (20) (see “Fitting the dust extraction adapter”, page 20).
- Insert the dust extraction adapter (20) 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 dust extraction adapter (20) must be opened. This will ensure that the automatic filter cleaning function works correctly. 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 (6) to the “automatic start/stop” symbol.
To activate the dust extractor, switch on the power tool that is plugged into the electric socket (4). 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, set the mode selector switch (6) 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 or burning 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.
- 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) in the floor nozzle (28). (see “Fitting the rubber lip (wet vacuuming) (see figure E)”.
- Switch off the automatic filter cleaning (AFC). (see “Automatic filter cleaning (see figure H)”, page 22)

Vacuuming up liquids

To switch on the dust extractor, set the mode selector switch (6) 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 (6) 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 (6) to the “switch off” symbol.
Empty the container (1).

To prevent mould growth after wet vacuuming:

Remove the flat-pleated filter (24) and leave this to dry thoroughly.
Remove the top part of the dust extractor (10), open the filter cover (34) and leave both elements to dry thoroughly.

Automatic filter cleaning

When automatic filter cleaning (AFC) is active, the flat pleated filter (24) is cleaned every 15 seconds using blasts of air (pulsating noise). The filter cleaning function should be used regularly, and at the very latest when the suction power is no longer sufficient. Regular use of the filter cleaning function will increase the service life of the filter. In order to achieve an optimum filter service life, deactivate the automatic filter cleaning function only in exceptional cases, e.g. when vacuuming pure liquids or using a paper filter bag.

A flat-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: The automatic filter cleaning function is switched on by default when the dust extractor leaves the factory. It is only possible to switch the automatic filter function on or off when the tool is switched on.

Deactivating AFC
- Press the AFC button (3).
- The control LED (33) will go out.
Activating AFC
- Press the AFC button (3).
- The control LED (33) will light up green.

Maintenance and Service
