IMPORTANT
SAFETY
INSTRUCTIONS
When using this floor machine, basic precautions should always be followed, including the following:
WARNING:
To reduce the risk of fire, electric shock or injury;
Read all instructions before using this floor machine.
1) DO NOT leave this machine plugged in
when not in use. Unplug from outlet when
not in use and/or before servicing.
2) Electric shock could occur if exposed to
rain. Store indoors.
3) This is NOT a toy. Close attention is necessary when used around or near children.
4) Use only as described in this manual.
Use only manufacturer's recommended
attachments.
5) DO NOT use with damaged cord plug. If
the floor machine is not working as it
should because it has been dropped, damaged, left outdoors, or dropped into water,
contact the manufacturer or authorized
service center.
This floor machine must be grounded. If it
GROUNDING
INSTRUCTIONS
should malfunction or breakdown, grounding
provides a path of least resistance for electrical current to reduce the risk of electric shock.
This machine is equipped with a cord having an
equipment-grounded plug. The plug must be
inserted into an appropriate outlet that is properly installed and grounded in accordance with
all local codes and ordinances
6) DO NOT pull or carry by cord, use
power cord as a handle, close a door on
cord, or pull cord around sharp edges or
corners. DO NOT run floor machine over
the cord. Keep cord away from heated surfaces.
7) DO NOT handle the plug or operate with
wet hands.
8) DO NOT put any object into the motor
openings.
9) DO NOT unplug by pulling on cord. To
unplug, grasp the plug, not the power cord.
10) Keep hair, loose clothing, fingers and
all parts of body away from moving parts.
11) DO NOT operate where oxygen or
anesthetics are used.
12) DO NOT use around flammable or
combustible liquids such as gasoline or use
in areas where they may be present.
13) DO NOT use an extension cord unless
absolutely necessary. If an extension cord is
used, then wire size must be #14 gauge or
thicker and should not exceed 50 feet in
length. Use only a 3 wire grounded extension cord to ensure grounding protection.
14) Replace damaged or worn parts
immediately with genuine original equipment parts to maintain safety and protect
your limited warranty.
If repair or replacement of the cord or plug is
necessary, DO NOT connect the grounding
wire to either flat blade terminal. The wire
with insulation having an outer surface that is
green with or without yellow stripes is the
grounding wire.
GROUNDING
METHODS
DANGER:
Improper use of the
grounding plug can
result in a risk of
electrical shock.
Improper connection of the equipment-grounding conductor can result in a risk of electrical shock. Check with a qualified
electrician or service person if you are in doubt as to whether the outlet is properly grounded. DO NOT modify the
plug provided with the burnisher. If it will not fit the outlet, have a proper outlet installed by a qualified electrician.
NOTE: In Canada, the use of a temporary adaptor is not permitted by the Canadian Electrical Code.
This floor machine is for use on a nominal
120 volt circuit, and has a grounding plug
that looks like the plug illustrated in (Fig A). A
temporary adaptor that looks like the adaptor
illustrated in (Fig B & C) may be used to connect the plug to a 2-pole receptacle as shown
in (Fig A) if a properly grounded outlet is not
available.
The temporary adaptor should be used only
until a properly grounded outlet (Fig A) can be
installed by a qualified electrician. The green
color rigid ear, lug, or like extending from the
adaptor must be connected to a permanent
ground such as a properly grounded outlet box
cover. Whenever the adaptor is used, it must
be held in place by the metal screw (Fig C).

DUAL SPEED
The Dual Speed Floor Machine
operates at 190 RPM for polishing or scrubbing and at 320 RPM
for spray buffing floors.
It is designed to be used with a
pad driver and pad, polish brush
or scrub brush on bare floors.
Begin operating the Dual Speed Floor
Machine at the closest point to your
electrical outlet and work away from
the outlet. This will prevent running over
the electric cord.
Always remove brush or pad driver
when machine is not in operation. Hung
brush on a wall peg or laid flat on its
back.
NEVER store the brush with bristles
down. This will ruin the balance of the
brush which will cause machine to
wobble.
If machine wobbles, vibrates or
pulls, follow theses instructions.
A. Never let machine set on brush,
pad driver or insta-lock when not in
use. A few minutes with machine setting idle on brush will cause bristles to
lose their normal shape, causing
uneven operation.
B. If wobble continues, adjust by turning brush
machine.
