General
 We recommend switching off the "Automatic filter
dedusting" function when vacuuming wet dirt with
the crevice nozzle or the upholstery nozzle (option-
al), or when sucking mainly water out of a container.
 The device switches off automatically when the
maximum fluid level is reached.
 When vacuuming non-conductive liquids (e.g. drill
emulsion, oils and grease) the device does not au-
tomatically switch off when the container is full. The
filling level must be continuously monitored and the
container emptied on a timely basis.
 On completion of wet vacuum cleaning: Clean the
main filter element using the filter cleaning. Clean
the electrodes with a brush. Clean the container with
a moist cloth and dry it off.
