7. Recheck the brush polish marks to see if the
front and rear match, and are even across
the full length of the brush.
8. The width of the rear brush polish mark can
vary more than the desired 1.5 to 2 in (40 to
50 mm). There are adjusting knobs located
on the drive side of the scrub head. Turn the
knob clockwise to decrease the width of the
polish mark and counterclockwise to
increase the width of the polish mark. The
polish mark should not exceed 2 in (50 mm).
Use the locking strips to keep the adjusting
knobs in place.

9. For maximum brush life, rotate the brushes
from front-to-rear after every 50 hours of
operation.
10. While scrubbing, refer to the brush pressure
gauge on the instrument panel. The pointer
should read in the “green” area. If the gauge
reads in the “red” area continuously, the
width of both brush patterns should be
narrowed.
