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 con-
nected to the tool's grounding system and 
must never be attached to an electrically 
“live” terminal.
Your tool must be plugged into an appropri-
ate outlet, properly installed and grounded in 
accordance with all codes and ordinances. 
The plug and outlet should look like those 
in Figure A.
Double Insulated Tools:
Tools with Two Prong Plugs
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. Double Insulated tools may be used 
in either of the 120 volt outlets shown in 
Figures B and C.
Grounded Tools:
Tools with Three Prong Plugs
Tools marked “Grounding Required” have a 
three wire cord and three prong grounding 
plug. The plug must be connected to a prop-
erly grounded outlet (See Figure A). 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.

Improperly connecting the grounding 
wire can result in the risk of electric 
shock. Check with a qualifi ed electri-
cian if you are in doubt as to whether 
the outlet is properly grounded. Do 
not modify the plug provided with 
the tool. Never remove the grounding 
prong from the plug. Do not use the 
tool if the cord or plug is damaged. 
If damaged, have it repaired by a 
MILWAUKEE  
service facility before 
use. If the plug will not fi t the outlet, 
have a proper outlet installed by a 
qualifi ed electrician.
