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 equipment should electrically
malfunction or break down, grounding provides a low resistance path to carry
electricity away from the user.
5. Double insulated equipment is 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 equipment to rain or wet conditions. Water entering
equipment will increase the risk of electric shock.
8. Do not abuse the Power Cord. Never use the Power Cord to carry the
equipment or pull the Plug from an outlet. Keep the Power Cord away
from heat, oil, sharp edges, or moving parts. Replace damaged Power
Cords immediately. Damaged Power Cords increase the risk of electric shock.
9. When operating equipment outside, use an outdoor extension cord
marked “W-A”or “W”. These extension cords are rated for outdoor use, and
reduce the risk of electric shock.
PERSONAL SAFETY

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 dam-
aged. 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 quali-
fied electrician.
GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS
1. Tools 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 tool should electrically malfunction or break down, grounding
provides 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 tool. The green wire in the cord must
be the only wire connected to the tool’s grounding system and must never be
attached to an electrically “live” terminal. (See Figure A.)
3. Your tool 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.)
FIGURE A
FIGURE B
DOUBLE INSULATEDTOOLS:TOOLSWITHTWO PRONG PLUGS
4. Tools marked “Double Insulated” do not require grounding. They have a special
double insulation system which satisfies OSHA requirements and complies
with the applicable standards of Underwriters Laboratories, Inc., the Canadian
Standard Association, and the National Electrical Code. (See Figure B.)
SKU 45005
For technical questions, please call 1-800-444-3353.

5. Double insulated tools may be used in either of the 120 volt outlets shown in
the following illustration. (See Figure B.)
EXTENSION CORDS
1. Grounded tools require a three wire extension cord. Double Insulated tools
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 tool damage.
(See Figure C.)
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 tool, add the nameplate
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.
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.
