How the airflow indicator works
The airflow indicator is designed to
show when the bag is full of common
household dust and measures the
amount of air flow through the filter bag.
Normal household dust is a mixture of
dust, hair, carpet fluff, threads, sand,
etc.
However, if fine dust, such as drill dust,
sand, plaster or flour is vacuumed, the
pores of the filter bag may become
blocked. The marker will indicate that
the bag is "full" even when it is not. The
filter bag should be changed as the
suction power is greatly reduced.
If the bag is bulging with pet fur, hair,
carpet fluff, etc. the indicator may not
register "full". This is because the air
flow of the filter bag may still be high
enough not to activate the marker to
show maximum. The filter bag should
still be changed.
Replacing the filter bag (see fig. 29 +
30)
^ Open the dust compartment lid and
raise until it clicks into place
(see fig. 11).
The filter bag has a closing flap which
closes automatically when the dust
compartment lid is raised to prevent
any dust from escaping.
^ Grasp the finger grip and pull the
filter bag out of the holder.
^ Insert the new filter bag as far as it
will go into the filter bag holder. Do
not unfold the filter bag when taking it
out of the box.
^ Unfold the filter bag in the dust
compartment.
^ Close the dust compartment lid until
it clicks into place. Take care not to
catch the filter bag in the lid.
,
A empty-operation-barrier will
block the dust compartment lid from
closing if no filter bag is inserted.
Do Not Use Force!
