This indicator shows when the dustbag

needs to be changed.

Only test with the rug and floor tool,

since other accessories can affect

the function of the dustbag change

indicator.

^ Set the suction power selector (if

present) to the highest setting 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

indicator window, even if the dustbag

is not completely full.

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 appears almost

empty. In this instance the dustbag

must be changed as suction power is

reduced when the pores of the dustbag

are blocked.

On the other hand, the bag may be

bulging with carpet lint or pet fur yet the

suction power may still be high enough.

The dustbag should be changed.

Either of these extremes can occur

during normal use. The dustbag

change indicator is designed for a

mixture of carpet lint, pet fur, hair, sand,

etc. vacuumed during normal

household cleaning.

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 lint, the indicator will

show only reduced suction when in

fact the bag is full.

^ Change the dustbag as soon as it

physically full, even if the dustbag

change indicator shows that it is not.
