grounded in accordance with all codes and ordinances. Never remove the
grounding prong or modify the plug in any way. Do not use any adapter
plugs. Check with a qualified electrician if you are in doubt as to whether
the outlet is properly grounded. If the tools should electrically malfunction or
break down, grounding provides a low resistance path to carry electricity away
from the user.
5. Double insulated tools are equipped with a polarized plug (one blade is
wider than the other). This plug will fit in a polarized outlet only one way. If
the plug does not fit fully in the outlet, reverse the plug. If it still does not
fit, contact a qualified electrician to install a polarized outlet. Do not
change the plug in any way. Double insulation eliminates the need for the
three wire grounded power cord and grounded power supply system.
6. Avoid body contact with grounded surfaces such as pipes, radiators,
ranges, and refrigerators. There is an increased risk of electric shock if your
body is grounded.
7. Do not expose this product to rain or wet conditions. Water entering an
electrically powered toy will increase the risk of electric shock.

GROUNDING
WARNING!
Improperly connecting the grounding wire can result in the risk of electric
shock. Check with a qualified electrician if you are in doubt as to whether the
outlet is properly grounded. Do not modify the power cord plug provided with
the tool. Never remove the grounding prong from the plug. Do not use the
tool if the power cord or plug is damaged. If damaged, have it repaired by
a service facility before use. If the plug will not fit the outlet, have a proper
outlet installed by a qualified electrician.
GROUNDED PRODUCTS: PRODUCTS WITH THREE PRONG PLUGS
1. Products marked with “Grounding Required” have a three wire cord and three
prong grounding plug. The plug must be connected to a properly grounded
outlet. If the unit should electrically malfunction or break down, grounding pro-
vides a low resistance path to carry electricity away from the user, reducing the
risk of electric shock. (See Figure A.)
2. The grounding prong in the plug is connected through the green wire inside the
cord to the grounding system in the product. The green wire in the cord must be
the only wire connected to the unit’s grounding system and must never be at
tached to an electrically “live” terminal. (See Figure A.)
3. Your product must be plugged into an appropriate outlet, properly installed and
grounded in accordance with all codes and ordinances. The plug and outlet
should look like those in the following illustration. (See Figure A.)

DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS
4. Products marked “Double Insulated” do not require grounding. They have a
special double insulation system which satisfies OSHA requirements and com-
plies with the applicable standards of Underwriters Laboratories, Inc., the Cana-
dian Standard Association, and the National Electrical Code. (See Figure B.)
5. Double insulated products may be used in either of the 120 volt outlets shown in
the following illustration. (See Figure B.)

OUTLETS
EXTENSION CORDS
1. Grounded products require a three wire extension cord. Double Insulated
products can use either a two or three wire extension cord.
2. As the distance from the supply outlet increases, you must use a heavier gauge
extension cord. Using extension cords with inadequately sized wire causes a
serious drop in voltage, resulting in loss of power and possible product damage.
(See Figure C, next page.)
3. The smaller the gauge number of the wire, the greater the capacity of the cord.
For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
(See Figure C.)
4. When using more than one extension cord to make up the total length, make
sure each cord contains at least the minimum wire size required.
(See Figure C.)
5. If you are using one extension cord for more than one product, add the name-
plate amperes and use the sum to determine the required minimum cord size.
(See Figure C.)
6. If you are using an extension cord outdoors, make sure it is marked with the
suffix “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.

SKU 94737 For technical questions, please call 1-800-444-3353 PAGE 9
7. Make sure your extension cord is properly wired and in good electrical condition.
Always replace a damaged extension cord or have it repaired by a qualified
electrician before using it.
8. Protect your extension cords from sharp objects, excessive heat, and damp or
wet areas.
