Grounding

TO PREVENT ELECTRIC SHOCK AND DEATH FROM INCORRECT GROUNDING

WIRE CONNECTION:

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

3-Prong Plug and Outlet

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 3-Prong Plug and Outlet.)

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 3-Prong Plug and Outlet.)

3. The 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 preceding illustration.

(See 3-Prong Plug and Outlet.)

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 Table A.)

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 Table A.)

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 Table A.)

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 Table A.)

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 the 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 the extension cords from sharp objects,

excessive heat, and damp or wet areas.
