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 cover.
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
cleaner.
OPERATION
As you vacuum, the red indicator light wilt
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 sensor.
The switch can
be set to HI (+) or LO (-) sensitivity
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 elec-
trical shock or personal injury from
cleaner suddenly starting.
TO CLEAN DIRT SENSOR OPTICS
The dirt sensor optics consist of two optic
celts located inside the dust bin port.
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 bin is cleaned,
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 bin.
