Wet extraction (see figure H)
- 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 M) have only been verified for dry extraction.
Steps to Take before Wet Vacuuming
- Remove the disposal bag (29) 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.
- Fit the rubber lip (32) in the floor nozzle (34) see Fitting the rubber lip (wet extraction) (see figure E).
- Switch off the automatic filter cleaning (AFC) see Automatic filter cleaning (see figure I).
Vacuuming up liquids
- To switch on the dust extractor, set the mode selector switch (7) to the "extraction" symbol.
The dust extractor is equipped with fill level sensors (40). The dust extractor shuts down if the maximum fill level has been reached. Set the mode selector switch (7) 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.
If the acoustic warning signal sounds during wet extraction, the operating reliability of the dust extractor is not affected. No measures to rectify the fault are necessary.
- To switch off the dust extractor, set the mode selector switch (7) to the "switch off" symbol.
- Pull the dump hose (23) from its holder and drain off the waste water through the dump hose.
- To transport the dust extractor, screw the sealing plug (2) onto the hose adapter (3).
- Empty the container (1).
To prevent mould growth after wet extraction:
- Remove the flat-pleated filter (30) and leave this to dry thoroughly.
- Remove the top part of the dust extractor (13), open the filter cover (39) and leave both elements to dry thoroughly.
