DIRT SENSOR
SOME MODELS
The electronic dirt sensor is a feature
which will detect particles as they pass
through the vacuum cleaner,
The dirt sensor indicators and sensor
sensitivity switch are located on the front
of the switch coven
A red light indicates dirt is being picked up
by the cleaner° A green light indicates
most of the dirt has been picked up by the
cleanen
OPERATION
As you vacuum, the red indicator light will
come on and stay on as long as the
sensor detects a high concentration of
particles passing through the cleaner.
The green light indicates that most of the
cleaning is complete.
The sensor switch allows you to select the
sensitivity of the dirt senson The switch
can be set to Ht (+) or LO (-) sensitivityr
Set the sensor switch to the HI (+)
position when:
•Cleaning bare floors.
,Cleaning carpet with low pile height
Set the sensor switch to the LO (-)
position when:
•Cleaning heavily soiled areas,
•Cleaning carpet with deep pile.
=Cleaning new carpets.
Even with the sensor switch in the LO (-)
position, the dirt sensor will detect carpet
fuzz, especially on new carpet, which may
cause the red light to remain on longer
than expected.

WARNING ............
Electrical Shock And Personal
Injury Hazard
Disconnect electrical supply before
servicing or cleaning the unit.
Failure to do so could result in
electrical shock or personal injury
from cleaner suddenly starting.
TO CLEAN DIRT SENSOR OPTICS
The dirt sensor optics consist of two optic
cells located inside the bag holder.
Occasionally, it may become necessary to
clean the two optic cells to assure
maximum performance, It is
recommended the optic cells be cleaned:
•When the red light stays on
continuously.
=When the green light stays on
continuously°
•When dirt or dust adheres to the
optic cells,
•Whenever the dust bag is changed.
To clean the sensor, wipe the optic cells
with a soft, dry cloth. Never use cleaners
or liquids as they can help speed the
recoating of the optic cells and make it
necessary to clean them much sooner
than normal° The dirt sensor area can be
reached by removing the dust cover and
the dust bag,,
