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 TOOLS: TOOLS WITH THREE PRONG PLUGS
1.
Tools and equipment 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 or equipment 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.
3.
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.)
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 that in the following illustration. (See Figure A.)

EXTENSION CORDS
1.
2.
Grounded tools and equipment require a three wire extension cord.
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 and
equipment damage. (See Figure B.)
3.
4.
5.
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 B.)
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 B.)
If you are using one extension cord for more than one tool or equipment, add the
nameplate amperes and use the sum to determine the required minimum cord
size. (See Figure B.)
6.
7.
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.
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. Protect your extension cords from sharp objects,
excessive heat, and damp or wet areas.
