3. Check singling brush for wear. If brush thickness is less than 3 mm (1/8 in.) or if upper tip of brush (A) is below top of green retaining brush (B) when assembled in meter, replace singling brush. Rate of brush wear varies with field conditions and is accelerated under sandy soil conditions.

4. Inspect green retaining brush for wear. Development of a groove in brush fibers above singling brush is an indication that singling brush needs to be replaced more frequently.

Wear of green retaining brush at cleanout "bump" (A) is normal and expected. Meter will operate properly with these fibers worn off.
