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 15 mm
(0.62 in).
NOTE: Replace worn brushes in pairs. Scrubbing
with brushes of unequal bristle length will result in
diminished scrubbing performance.
REPLACING OR ROTATING CYLINDRICAL
BRUSHES
1. Stop machine on a level surface. Make sure
the scrub head is in the raised position.
2. Turn the machine
ON/OFF key switch
off.
FOR SAFETY: Before leaving or servicing
machine, stop on level surface, turn off
machine, and remove key.
3. Remove the cotter pin that holds the side
squeegee in place. Swing the squeegee away
from the scrub head.
4. Remove idler plate from the scrub head by
pressing the spring tab downward.
5. Pull the old brush out of the scrub head.
6. Attach the idler plate to the new or rotated
brush on the end that has the double row of
bristles. Install the brush.
7. Push down on the door to catch the door in
the scrub head, then pull up on the door to
latch it into the spring.
8. Repeat for the other brush on the other side
of the scrub head
NOTE: Each side of the scrub head is stamped
with a letter. The idler door of that side of the
scrub head is stamped with the same letter. Make
sure the letter on the door matches the letter on
the scrub head when replacing the doors.
