DIRT SENSOR
The electronic dirt sensor is a feature

through the vacuum cleaner.
The dirt sensor indicator is located on the
front of the vacuum cleaner above the dust
bin.
Sensor
A red light indicates dirt is being picked up
by the vacuum cleaner.
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 vacuum cleaner.
II, WARNING
Electrical Shock And Personal Injury
Hazard
Disconnect electrical supply before per-
forming maintenance to the unit. Failure
to do so could result in electrical shock
or personal injury from vacuum cleaner
suddenly starting.
TO CLEAN DIRT SENSOR OPTICS
The dirt sensor optics consist of two optic
cells 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 dirt or dust adheres to the
optic cells.
• Whenever the dust bin is emptied.
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.
