GROUNDING

TO PREVENT ELECTRIC SHOCK AND DEATH FROM

INCORRECT GROUNDING WIRE CONNECTION:

Check with a qualied 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 t the outlet, have a proper outlet installed by a qualied

electrician.

Grounded Tools: Tools with Three Prong Plugs

Tools marked with “Grounding Required” have a three wire cord and three prong1.

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.)

The grounding prong in the plug is connected through the green wire inside the2.

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.)

The tool must be plugged into an appropriate outlet, properly installed and ground-3.

ed 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.)
