4.6 Appliance plug with automatic switch-on/off
function for electronic tool / dust generator
The dust extractor is equipped with a socket outlet 4
(fig. 1) and automatic switch on/off function for
electrical tools.
To ensure that the entire dust is still vacuumed after
switch off and while the electrical tool is coasting
down, the electronic system only switches off the
vacuum cleaner approx. 3-5 seconds after the
electrical tool is switched off.

4.7 Volume flow display

The fixed value of the volume flow display 3 (fig. 1) is
set such that when the average air speed in the hose
system drops below 20 m/s, the control display 3
blinks as indication that the filter bag or the container
is full.
