FILTER CHANGE
INDICATOR (Fig. 12)
The red lamp of the
electric filter change
indicator lights up when
the filter bag has to be
changed or when the
suction channel is
clogged.
The filter change indicator
evaluates the air
permeability of the twin-
ply filter bag.
Filter bag empty:
No reaction of the
indicator (high air
permeability)
Filter bag full:
The filter change
indicator lights up
(filter bag not
permeable to air)
The filter bag has
to be replaced.
Please note that when
picking up cement,
plaster or extremely fine
dusts, the air permeability
of the filter bag can be
impaired to such an
extent that the filter
change indicator lights up
although the filter bag is
still relatively empty. In
this case the filter bag has
to be replaced because
otherwise the suction
power will be excessively
reduced. If the filter
change indicator remains
lit even after changing the
filter bag, the suction
channel (tube, nozzles,
suction hose, hose fitting
or filter bag) is clogged.
After clearing the clog-
ging, the red indicator
light goes out.
MAINTENANCE
Before maintenance
and repair work,
remove the mains plug
from the plug socket!
OPENING THE SUCTION
UNIT (Fig. 13)

INSERTING THE FILTER
BAG (Fig. 14)
Push the filter bag with
the reinforcing sleeve onto
the fitting of the suction

has been fitted.
Please use original filter
bags as these are
optimally designed for
the function of the
cleaner.
No claim under
warranty will be
accepted for any
damage resulting from
the use of filter bags of
other brands.
Filter bags can be re-
ordered under the Order
No. 64895.

REPLACING THE MICRO

the filter cassette upwards
out of the guide.
Open the cassette and
replace the micro exhaust
air filter, close the cassette
again and push into the
guide up to the stop.
