When to change the filter bag (see
fig. 32)
Change the filter bag when the colored
marker in the airflow indicator
completely fills the display in red.
Filter bags are disposable and are
designed to be used only once.
Dispose of full filter bags. Do not
attempt to reuse.
Clogged pores reduce the suction
power of the vacuum cleaner.
Check the airflow indicator
^ Attach the standard floor brush,
AllTeQ or AirTeQ to the vacuum
cleaner. All other suction tools may
affect the function of the airflow
indicator.
^ Switch the vacuum cleaner on and
select the highest power level.
^ Lift the floor brush slightly off the
floor. If the marker completely fills the
indicator window, the filter bag needs
to be changed.
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.
How to change the filter bag (see fig.
33 + 34)
^
Lift the release button and open the
dust compartment lid upwards until it
clicks into place.
The filter bag has a flap that
automatically closes to prevent dust
from escaping when the bag is
removed.
^ Grasp the collar and remove the filter
bag from the holder.
^ Insert the new filter bag into the blue
holder as far as it will go. Note: Do
NOT unfold the filter bag when you
take it out of the box.
^
Unfold the filter bag in the dust
compartment when possible.
^
Now close the dust compartment lid
until it clicks into place, take care not
to catch the filter bag in the lid.
,
If you do not insert a replacement
filter bag, the dust compartment lid is
designed not to close. Do not use
force!
