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.)

Double Insulated Tools: Tools with Two prong plugs

 

Outlets for 2-prong plug

1.  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.

2.  Double insulated tools may be used in either of the 

120 volt outlets shown in the preceding illustration.

   

(See Outlets for 2-prong plug.)
