TO CLEAN DIRT SENSOR OPTICS
The dirt sensor optics consist oftwo optic
cells located insidethe bag holder,,
Occasionally, itmay become necessary to
clean the twooptic cells to assure maximum
performance. It isrecommended the optic
cells be cleaned:
• When the red light stays on
continuously,
• When the green light stays on
continuously.
• When dirt ordust 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.
