# 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.

## 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).
- Switch off the automatic filter cleaning (AFC).

## 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), 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 extraction:

- 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.
