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,,
