Safety Devices

Monitoring of the flat fold filter
If the device is operated without a flat fold
filter, it automatically switches off.
 If necessary, peel the adhesive label in
the relevant national language off the
accompanying adhesive label sheet
and paste it over the German text on
the appliance.
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.
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.
Interval tone
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.
Permanent tone

place the cooling air filter.

Anti-static system
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).
