When to change the dustbag

^ Change the dustbag as needed.
The dust bags are disposable and
intended to be used only once. Do
not attempt to reuse.
Checking the dustbag change
indicator
^ Attach the floor brush to the vacuum
cleaner. Only test with the floor brush,
other accessories can affect the
function of the dustbag change
indicator.
^ Set the suction power selector (if
present) to the highest setting and
make sure the air inlet valve is
closed.
^ Hold the wand off the floor and turn
on the vacuum claner. If the marker
completely fills the indicator window,
change the dust bag even if it is not
completely full.

How the dustbag change indicator
works
The indicator shows a decrease in the
vacuum performance, independent of
the actual fullness of the bag.
If fine dust, such as drill dust, sand,
plaster or flour is vacuumed, the pores
of the dustbag become blocked. The
marker will indicate that the bag is "full"
even when it is not. The dustbag 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 dustbag may still be high
enough not to activate the marker to
show maximum. The dustbag should
still be changed.
