SCRUB ATTACHMENT
SCRUB ATTACHMENT
The scrub attachment accessory gives the machine
the added flexibility to scrub floors. It consists of
three groups of parts --- the scrub attachment, the
side scrub brush and squeegee, and the rear
squeegee. The scrub attachment includes two
solution tanks, a solution distribution system, three
scrub brushes, a recovery tank, and a debris hopper.
SOLUTION TANKS
The two solution tanks supply the scrub brush with a
water and detergent solution. They are located in the
top right and left sides of the scrub attachment.
Access to the tanks is through the solution tank
covers on the top of the scrub attachment.
The solution tanks require no regular maintenance. If
detergent cakes on the bottom of the tank, remove
the deposits with a strong blast of water.
SOLUTION DISTRIBUTION SYSTEM
The solution is distributed by feed lines from the
solution tanks to an on-off solenoid valve, to a cable
controlled flow-rate valve, then to a solution spreader
tube.
The solution spreader tube distributes scrub solution
to the scrub brushes. It may be flushed out if it
becomes clogged. A drain plug is located on each
end of the spreader tube.
Before cleaning the solution spreader tube, make
sure that the cable controlled flow-rate valve is
opening fully when the solution flow knob is pulled
out.
A brush and hot water may be needed to remove
stubborn clogs. A sharp instrument may be used to
clear the small distribution holes in the spreader
tube.

SCRUB BRUSHES
Three scrub brushes are utilized by the scrub
attachment --- the side brush, the main brush, and a
scrub brush located in the scrub attachment. The
side brush scrubs and deflects debris into the path
of the scrub brush. The scrub brush scrubs and
deflects debris backward, the main brush scrubs
and deflects debris into the debris hopper.
The brushes should be inspected daily for damage
or wear. Remove any string or wire found tangled on
the scrub brushes, drive, or idler hubs.
Replace the scrub brushes when the brush bristle is
0.5 in (15 mm) or less in length. To replace the side
brush, see TO REPLACE SIDE BRUSH . To replace
the scrub brush, see TO REPLACE SCRUB BRUSH .
To replace the main brush, see TO REPLACE MAIN
BRUSH
.
The scrub brush patterns should be checked daily.
They should be 2 to 3 in (50 to 75 mm) wide. The
scrub brush pattern is adjusted by changing the
position of the clevis on the threaded stud of the lift
linkage. See
