3. SCRUB BRUSHES
There are four 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.
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.
Polypropylene
is a general-purpose scrub brush
with stiff bristles. Polypropylene works well for
maintaining concrete, wood and tile floors.
FINISHED 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.
Black 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.

4. RECOVERY TANK FLOAT SHUT-OFF
When water is no longer being vacuumed from the
floor and the vacuum fan is operating, the ball float
has engaged. The vacuum motor will not vacuum
water with recovery tank full. The recovery tank
must be drained.

with one hand and the connected tube with the
other. Tilt and pull the float screen assembly to
pull it off the barb on the tube.
To install, place one hand on the tube, and then
