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

Figure A:  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 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.  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 Figure A.)

Double Insulated Tools: Tools with Two prong plugs

Figure B:  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 Figure B.)
