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

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 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

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 connected to a properly grounded

outlet (See Figure A). If the tool should

electrically malfunction or break

down, grounding provides a low re-

sistance 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

standards of Underwriters Labora-

tories, Inc., the Canadian Standard

Association and the National Electri-

cal Code. Double Insulated tools may

be used in either of the 120 volt out-

lets shown in Figures B and C.
