➢ ➢ When the vacuum cleaner is running
with normal air flow, the light on the
performance indicator is off. The
light comes on whenever the airflow
becomes blocked. If that occurs,
check the dust bin clean/replace
clogged filters, and check other
possible clog locations shown in
CLOG REMOVAL. The light may also
come on when using attachments,
due to reduced airflow through the
attachment. In some cases, the
performance indicator light may not
come on if the motor protector has
opened.
➢ ➢ The dirt sensor optics consist of two
optic cells located inside the suction
inlet. Occasionally, it may become
necessary to clean the two optic cells
to assure maximum performance.
➢ ➢ Clean optic cells:
• When dirt or dust adheres to the
optic cells.
• Whenever the dust bin is cleaned.
➢ ➢ To clean the dirt sensor optics,
remove the dust bin.
➢ ➢ With the dust bin removed you can
insert a cloth into the suction inlet
opening.
➢ ➢ 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.
