Grounded tools require a three wire extension cord. Double insulated tools 
can use either a two or three wire extension cord. As the distance from the 
supply outlet increases, you must use a heavier gauge extension cord. Us-
ing extension cords with inadequately sized wire causes a serious drop in 
voltage, resulting in loss of power and possible tool damage. Refer to the 
table shown to determine the required minimum wire size.
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. When using more than one extension cord to make up the total 
length, be sure each cord contains at least the minimum wire size required. 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 wire size.
Guidelines for Using Extension Cords
• 
If you are using an extension cord outdoors, be sure it is marked with 
the suffi x “W-A” (“W” in Canada) to indicate that it is acceptable for 
outdoor use.
• 
Be sure your extension cord is properly wired and in good electrical  
condition. Always replace a damaged extension cord or have it repaired 
by a qualifi ed person before using it.
• 
Protect your extension cords from sharp objects, excessive heat and  
damp or wet areas.
GROUNDING
EXTENSION CORDS
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 properly 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 electrician 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.

READ AND SAVE ALL INSTRUCTIONS 
FOR FUTURE USE.
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.
Your 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 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.
