5.0 Brush Construction
Your new floor machine provides reliable, efficient, safe
power to your scrubbing brush. To get the best results, you
need to use a brush of the best design and construction.
Your floor machine is built with a “B” style drive plug (1).
The height and width of the ears on the plug will match a
“B”-style or a “Universal” clutch plate (2) mounted on the
brush block.
The brush block (3) is constructed of molded plastic or
thick plywood. Use a brush with a block diameter
2” less than your machine apron size.
The bristle material (4) that actually does the scrubbing is
typically 1-1/2” to 2” long. Holes are drilled in the block and
bundles of bristles are folded in half, forced into the
hole and stapled in place (staple-set).
When the bristles wear down to less than 1/2” long, they
have little flexibility and it’s time to replace. Bristle
materials are described on page 11.
5.1 Pad Driver Construction
If you scrub or polish with a non-woven pad, use a pad
driver to connect the pad to the machine.
The brush block (3) is constructed of molded plastic, fit
with shorter, stiffer, pad-holding bristles (5) or “velcro-like”
pad-holding hooks (6) and use a riser (7) to create
extra clearance between the block and the machine apron.
With this construction use a pad driver with block diameter
1” less than your machine apron size.

1.1 Electric Power
This floor machine operates on a 15 amp nominal 115V, 60 HZ, A.C.
power circuit. (Motors may be custom wired at the factory for 220 V,
50 Hz international operation.) The amp, hertz, and voltage ratings
are listed on the motor spec label found on each machine. Using
voltages above or below those indicated on the spec label will
damage the motor. Always check your local voltage requirements.
This floor machine must be grounded while in use to protect the
operator from electrical shock. This floor machine is built with a 3-
wire cord and a 3-prong grounding type plug (Figure 1) to fit the
properly grounded receptacle.
Before using this floor machine, make sure a properly
grounded, 3-hole electrical outlet is available. If not, as in
some older facilities, use an adapter for connecting a 3-prong
plug to a 2-prong receptacle (Figure 2) to ground to the outlet
chassis.
IMPORTANT!!
This adaptor may not be used in Canada.
IMPORTANT!!
Never cut off the grounding prong for use in a 2-prong
outlet. By doing so, you have cut off your protection from electrical
shock.
Never assume that all 3-hole outlets are properly grounded.
Never assume that an adaptor connection (as in Figure 2) is properly
grounded. Check the outlet with a ground fault interrupter device which quickly
indicates if a ground is connected. Correct a faulty grounding before
proceeding.
This floor machine is shipped with a 50 foot (15 M) long safety cord which
plugs directly into an approved outlet. The use of an extension cord is not
recommended.
