Warning
The flat pleated filter must always be in
place while vacuuming.
ṇ
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 when the air speed falls be-
low 20 m/s.
Note: The horn reacts to negative pressure.

Set the rotary switch to the correct suc-
tion hose cross-section.
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.
– The device is fitted with a paper filter
bag with locking slide, order no. 6.904-
208.0 (5 pcs).
Note: You can use this appliance to take up
all types of dust up to dust class M. It is stat-
utorily necessary to use a dust collection
bag (see Filter systems for order number).

vacuum cleaner and as dedusting device
for the mobile operation to take up dry, non-
combustible dusts with MAK values greater
than or equal to 0.1 mg/m
