CYLINDRICAL BRUSHES
Check the brush taper and rotate the brushes
from front-to-rear every 50 hours of machine
operation for maximum brush life and best
scrubbing performance.
The cylindrical brushes should be replaced if large
amounts of bristles are missing, or if the
remaining bristle length is less than 10 mm
(0.38 in).
NOTE: Replace worn brushes in pairs. Scrubbing
with brushes of unequal bristle length will result in
diminished scrubbing performance.
NOTE: Fill the solution tank before checking or
adjusting the brush pattern.
CHECKING AND ADJUSTING CYLINDRICAL
BRUSH PATTERN
1. Apply chalk (or another material that will not
easily blow away), to a smooth, level section
of the floor.
2. Set the parking brake.
3. Lower the scrub head in the chalked area.
Allow the machine to scrub in the same
place for 15 to 20 seconds.
NOTE: If chalk or other material is not available,
allow the brushes to spin on the floor for two
minutes. A polish mark will remain on the floor.
4. Raise the scrub head and move the machine
away from the chalked area. Turn the
machine power off.
