IMPORTANT
SAFETY
INSTRUCTIONS
WARNING:
To reduce the risk of fire, electric shock or injury:
When using an electric floor machine,
basic precautions should always be followed, including the following:
1) DO NOT leave this floor machine
plugged in when not in use. Unplug the
machine from the outlet when not in use
and 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 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.
6) DO NOT pull or carry by cord, use the
power cord as a handle, close a door on
cord, pull cord around sharp edges or corners.
7) DO NOT run the machine over the
cord. Keep the cord away from heated
surfaces.
8) DO NOT unplug by pulling on cord. To
unplug, grasp the plug, not the power
cord.
9) DO NOT handle the plug or operate
with wet hands.
10) DO NOT put any objects into motor
openings.
11) Keep hair, loose clothing, fingers and
all parts of the body away from moving
parts.
12) DO NOT operate the machine where
oxygen or anesthetics are used.
13) DO NOT use around flammable or
combustible liquids such as gasoline or
use in areas where they may be present.
14) 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 threewire grounded extension cord to ensure
grounding protection.
15) Replace damaged or worn parts
immediately with genuine original equipment parts to maintain safety and to protect your limited warranty.
16) Floor sanding can result in an explosive mixture of fine dust and air. Use a
floor sanding machine only in a well ventilated area.
WARNING:
DO NOT use this floor machine for sanding
possible motor damage may occur and the mixture of
fine dust and air can result in an explosive.
Use a floor sanding machine only in a well ventilated area.

DANGER:
Improper use of the grounding plug can result in a
risk of electric shock.
GROUNDING
INSTRUCTIONS
This floor machine must be grounded. If it
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.
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.
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
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 the
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).
WARNING:
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.
Treat this floor machine as you would any
other high grade precision made product.
Throwing, dropping, unreasonable bumping across thresholds and other misuse
may result in a damaged unit and invalidate the warranty.
