DIRT SENSOR
The electronic dirt sensor is a feature
which will detect particles as they pass
through the vacuum cleaner.
The dirt sensor indicators is located on
the front of the switch cover.
A red light indicates dirt is being picked up
by the vacuum cleaner. A green light
indicates most of the dirt has been 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.
! WARNING
Electrical Shock And Personal Injury
Hazard
Disconnect electrical supply before
performing maintenance to the unit.
Failure to do so could result in elec-
trical 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 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 ceils.
• 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.
