General
 We recommend not using the
"Semi-automatic filter dedusting"
function button when vacuuming
wet dirt with the crevice nozzle or
upholstery nozzle (optional) when
sucking mainly water out of a con-
tainer.
 The device switches off automatical-
ly when the maximum fluid level is
reached.
 When vacuuming non-conductive
liquids (e.g. drill emulsion, oils and
grease) the device does not auto-
matically switch off when the con-
tainer is full. The filling level must be
continuously monitored and the con-
tainer emptied on a timely basis.
