Maintenance and care
Suction Level Indicator
Only test the vacuum’s suction level indicator with the rug and floor tool attachment. Using any other attach- ment will give an inaccurate reading.
^Set the suction power selector, (ac- cording to model), to the highest set- ting and close the air inlet valve.
^Lift the rug and floor tool off the floor.
^The dustbag should be changed if the red marker completely fills the in- dicator window, even if the dustbag is not completely full.
Please note:
The indicator measures the airflow through the dustbag.
Vacuuming up even a small bit of fine dust such as flour, ash or powder can cause enough of a drop in airflow to cause a "full bag" indication, even though the dustbag may appear almost empty. Since the airflow (suction power) is greatly reduced, the bag should be changed. On the other hand, the dustbag may be bulging with carpet lint or pet fur yet the airflow may still be high enough to prevent the suction level indicator from registering "full". If this occurs the dustbag should be changed.
Either of these extremes can occur dur- ing normal use.
The suction level indicator is designed to work when a mixture of the above items, along with hair, sand, etc . are vacuumed, as is generally the case when using the vacuum for normal household cleaning.
We recommend that:
1.If you vacuum a lot of fine dust or sand:
^Change the dustbag as soon as the red marker fills the indicator window, even if the bag is not full.
2.If you vacuum a lot of hair, pet fur or loose carpet fibers: the suction level indicator will show only reduced suc- tion when in fact the bag is full.
^Change the dustbag as soon as it physically full, even if the suction level indicator shows that it is not.
