TO CLEAN DIRT SENSOR OPTICS
The dirt sensor optics consist of two optic
cells located inside the dust bag 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 celts_
• Whenever the dust bag is removed.
Optic Cells
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 bag.
