SCRUB HEAD-CYLINDRICAL
The dual cylindrical scrub head is designed to
eliminate debris that may be caught in the squeegee
while scrubbing. Water is applied to the first
scrubbing brush turning in a clockwise rotation when
viewed from the right of operator’s side of machine.
The first brush scrubs dirt and debris between the
brushes. The second scrubbing brush, turning in a
counter clockwise rotation, picks up debris and
throws it into a removable hopper. The larger debris
which might catch under the squeegee is collected
in the hopper. Water is allowed to drain out the
hopper into the squeegee path where it is recovered
from the floor.
MAINTENANCE
The brushes should wear evenly side to side if
properly adjusted. Scrub brushes should be
exchanged front to back every 50 hours to ensure
even wear since the rear brush contacts the floor
with more force. It is not necessary to rotate end for
end since swapping front to back puts the brushes in
the opposite rotation, as well as balancing wear.
Scrub brushes should be replaced as a set when
bristle length wears to height of yellow
