MAINTENANCE
CYLINDRICAL SCRUB BRUSHES
Rotate the brushes from front-to-rear after every
50 hours of operation.
Replace the brushes when they no longer clean
effectively.
NOTE: Replace worn brushes in pairs. Scrubbing
with brushes of unequal bristle length will result in
diminished scrubbing performance.
