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. Using
extension cords with inadequately sized wire causes a serious drop in volt-
age, 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 name-
plate 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
suffix “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 qualified 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 con-
nected to a properly grounded outlet
(See Figure A). If the tool should elec-
trically 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 qualified
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 fit the outlet, have a proper outlet installed by a
qualified 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 stan-
dards of Underwriters Laboratories,
Inc., the Canadian Standard Associa-
tion and the National Electrical Code.
Double Insulated tools may be used
in either of the 120 volt outlets shown
in Figures B and C.
