SCRUB BRUSHES
The scrub brushes are tubular and run the width
of the scrub head, sweeping debris into the debris
trough while they scrub the floor. The brushes
should be inspected daily for damage or wear.
Remove any string or wire found tangled on the
scrub brushes, drive, or idler hubs.
Rotate the scrub brushes from front-to-rear after
every 50 hours of operation for maximum brush
life and best scrubbing performance.
The scrub brush patterns should be checked
daily. The scrub brush pattern is adjusted by
turning the adjustment knobs on top of the scrub
head. See TO ADJUST SCRUB BRUSH
PATTERN . The width of the patterns should be
1.5 to 2 in (40 to 50 mm).
