# 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.

Note: The requirements for the degree of penetration (dust class L) have only been verified for dry vacuuming.

##

Empty the container (1) and remove the plastic bag (32) or the fleece filter bag (40).

Check the fill level sensor (45) for dirt. The fill level sensor must be clean in order for the dust extractor to switch off automatically when the container is full see Cleaning the fill level sensor (see figures Q–R).

- During wet extraction, the automatic filter cleaning function must be deactivated.

Press the automatic filter cleaning button (8) to activate manual filter cleaning see Manual Filter Cleaning. This deactivates automatic filter cleaning and LED indicator A (5) goes out.

WARNING

If you notice a foam or water leak, switch off the vacuum cleaner immediately and empty the container. Otherwise, the vacuum cleaner can become damaged.

To switch on the dust extractor, turn the main switch (2) to position 1.

The dust extractor is equipped with fill level sensors (45). If the maximum fill level has been reached, the dust extractor automatically switches off and the two LED indicators A (5) and M (6) flash simultaneously once a second. Restart protection is activated and can be deactivated by switching the dust extractor on and off once.

Note: Check the fill level regularly and empty the container in good time.

To switch off the dust extractor, turn the main switch (2) to position 0.

Hold the container (1) in the rear handle section (21) and twist it forwards to drain the liquid.

##

After wet vacuuming, always clean the fill level sensor (45) see Cleaning the fill level sensor (see figures Q–R).

To prevent mould growth after wet extraction:

- Remove the flat-pleated filter (34) and leave this to dry thoroughly.
- Remove the top part of the dust extractor (12), open the filter cover (43) and leave both elements to dry thoroughly.
