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 exten-
sion cord. Using extension cords with inadequately sized wire causes a
serious drop in voltage, resulting in loss of power and possible tool dam-
age. 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 mini-
mum 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 re-
paired 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 pro-
vided 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
standards of Underwriters Laborato-
ries, Inc., the Canadian Standard As-
sociation and the National Electrical
Code. Double Insulated tools may be
used in either of the 120 volt outlets
shown in Figures B and C.
