The appliance allows 2 operating modes:

2 Dedusting mode (socket used)
 Connect the suction hose and insert in-
sert the suction nozzle or connect to the
dust-generating device depending on
the operating mode.
Warning
Do not vacuum without the filter elements;
otherwise, the suction motor can get dam-
aged and this can be hazardous to health
on account of increased release of fine dust
particles.

low 20 m/s.

sure.
 Set the rotary switch to the correct suc-

Anti-static system
Static charge is deflected by providing
earthing to the connection nozzles. This
prevents the formation of sparks and cur-
rent shocks due to attachments (option)
with electrical conductivity.
