CYLINDRICAL SCRUB SYSTEM
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 or 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.
The design of the touch panel permits the same
automatic operating procedure as the disc machine.
DUMPING HOPPER
The removable hopper is located behind the rear
scrub brush. Remove the hopper by sliding it our
from the right side of the machine. The hopper can
then be dumped from the top or the left side door
can be removed to dump debris from the end. The
side door is also convenient for flushing the hopper
clean.
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. 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 Perform Alert
bristle.

The scrub brushes are removed from the sides of
the machine. The front is removed from the right
side and the rear is removed from the left side.
