CAUTION
DIRT SENSOR MAINTENANcE
Although the dirt sensor feature in your vacuum cleaner is designed for years
of trouble free use, the passage of dirt through the air passage system can
coat the lens causing the dirt sensor light MIN to come on and stay on never
switching to MAX. When this happens the lenses must be cleaned.
Never use water or any cleaning solution when cleaning the lenses. The residue
of the water or cleaners will accelerate the recoating of the lenses and make
cleaning necessary sooner.
To Clean the Lenses
1. Remove the smart diverter as described in 'Smart
Diverter Maintenance' section pg.17.
2. As indicated by the illustration, the two dirt sensor lenses
are located on the inside of the body, approximately
2inches/ 50mm up (note the arrows) from the smart
diverter.
These lenses should be cleaned periodically. To reach
the sensor lenses, use a small brush such as a bottle
brush. Brush each sensor lens several times to remove
dust and dirt.
