SCRUB BRUSHES
NOTE: All original equipment brushes are
equipped with “Perform Alert
©
”. This feature will
tell the operator when it is time to replace the
scrub brushes. “Perform Alert
©
” brushes have
pre-trimmed bright yellow tufts to indicate the
length of a worn out brush. When the tufts in the
scrub brush wear to a length equal to the yellow
tufts, the scrub brushes should be replaced.
There are five 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 and further add to the flexibility of the
machine.
Please refer to the following to assist in selecting
the proper brush or pad for the work at hand.
UNCOATED FLOORS
Aggressive Grit is a nylon fiber impregnated with
silicone carbide grit. It grinds away stain, soil, and
removes surface material.
Mild Grit is a less aggressive silicone carbide grit
suitable for cleaning medium soil conditions.
Advantages are faster ground speed than nylon
bristles on light solid applications.
Nylon is a general-purpose scrub brush with stiff
bristles. Polypropylene works well for maintaining
concrete, wood and tile floors.
FINISHED FLOORS
Nylon Polish
is the softest brush. It will gently
clean finished tile or terrazzo floors without
removing floor finish or floor material. Used for
washing highly polished or burnished 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-duty
scrubbing and light stripping. The blue pads
remove less finish than brown stripping pads, yet
will remove black marks, stains and dirt.
Brown Pads (Stripping) are used for easy and
complete removal of old floor waxes/finishes.
They will quickly remove ground in dirt, black heel
marks, and spills. When used with the proper
stripper, this pad leaves the floor clean and ready
for finishing.
The scrub brushes should be checked before each
days work for wire, string, wear and damage. The
scrub brushes should be replaced if brush bristles
are missing or if yellow Perform Alert
