by the cleaner. A green light indicates most
of the dirt has been picked up by the
cleaner.

come on and stay on as long as the sensor
detects a high concentration of particles
passing through the cleaner.

The green liglit indicates tliat most of the

cleaning is complete

The sensor switcli allows you to select lire
sensitivity of the dirt sensor. The switch can
be set to HI {+) or LO (-) sensitivity.

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 the green light stays on

continuously.

•When dirt or dust adheres to the

optic cells,

•Whenever the dust bin is cleaned.

To clean the sensor, wipe the optic cells with

a soil, 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.
