Maintenance
Squeegee Blades
The front squeegee blade allows solution to pass
through channels in the blade into the squeegee
assembly while maintaining vacuum to provide lift. The
front blade has four wear surfaces and can be rotated
for extended life. The front blade should not require
regular replacement under normal use.
The rear blade wipes the floor to a near dry condition. It
is important the rear blade be in good condition to
properly do its job. As with the front, each squeegee
blade assembly has four wear surfaces for extended
service.
Check both the front and rear squeegee blades for
damage and wear each day in the pre-run check.
Change the front blade if it is torn or has an uneven
edge. Change the rear blade if it is less than half the
original thickness.

Scrub Brush
There are different types of brushes available to cover
applications from cleaning heavily soiled floors to
polishing. A pad driver is also available to take
advantage of the many cleaning pads on the market.
Please refer to the following to assist in selecting the
proper brush or pad for the work at hand.
Finished Floors
Polypropylene is a general-purpose scrub brush with
stiff bristles. Polypropylene works well for maintaining
grouted tile floors.
Nylon bristles are used in a variety of applications on
coated or uncoated surfaces.
White Pads (Polishing) are used for dry polishing to
achieve a high-gloss appearance, or surface washing
on highly polished or burnished floors.
Red Pads (Buffing) are used for light-duty scrubbing.
When used with a mild detergent they will provide
surface cleaning without removing the finish.
Blue Pads (scrubbing) are used for heavy scrubbing
and light top scrubbing. The blue pads remove black
marks, stains and dirt. The blue pad may also remove
some floor finish.
Black pads (top scrubbing) are used to remove ground
in soil and the top layers of floor finish to prepare for
recoating.
The scrub brushes should be checked before each
days work for wire, string, wear and damage.
