Operating instructions

– 3
If the device is operated without a flat fold
filter, it automatically switches off.
The appliance allows 2 operating modes:
1 Industry vacuum cleaner mode (socket
not used)
2 Dedusting mode (socket used)
 Connect the suction hose and insert the
suction nozzle or connect to the dust-
generating device depending on the op-
erating mode.
몇 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.
The horn blows (interval tone) when the air
speed falls below 20 m/s.
Note: The horn reacts to negative pres-
sure.
 Set the rotary switch to the correct suc-
tion hose cross-section.
The horn blows (permanent tone) when the
cooling air filter is clogged.
 Allow appliance to cool down. Clean/re-
place the cooling air filter.
Static charge is deflected by providing
earthing to the connection nozzles. This
prevents the formation of sparks and cur-
rent shocks with attachments with electrical
conductivity (included in the delivery).
