Sensor
The dirt sensor indicator is located on the
front of the vacuum cleaner as illustrated.
A red light indicates dirt is being 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.
Electrical Shock And Personal
Injury Hazard
Disconnect electrical supply before
servicing or cleaning the unit.
Failure to do so could result in
electrical 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 dust bin port
assembly. Occasionally, it may become
necessary to clean the two optic cells to
assure maximum performance.
Clean optic cells:
• When the red light stays on
continuously.
• When dirt or dust adheres to the optic
cells.
• Whenever the dust bin is cleaned.
To clean the dirt sensor optics, remove
Dust Bin as outlined in the (Dust Bin
Cleaning section).
With the dust bin removed you can insert a
cloth into the dust bin port opening.

Cells

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.
