GROUNDING
WARNING!
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 quali-
fied electrician.
Grounded Tools:
Tools with Three Prong Plugs
Tools marked "Grounding Required" have
a three wire cord and three prong ground-
ing 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.
Fig. A
The grounding prong in the plug is con-
nected 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 ground-
ing system and must never be attached to
an electrically "live" terminal.
Your tool must be plugged into an appro-
priate 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 re-
quire grounding. They have a special
double insulation system which satisfies
OSHA requirements and complies with the
applicable standards of Underwriters Labo-
ratories, Inc., the Canadian Standard As-
sociation and the National Electrical Code.
Double Insulated tools may be used in ei-
ther of the 120 volt outlets shown in
Figures B and C.

EXTENSION CORDS

Grounded tools require a three wire ex-
tension 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 voltage, resulting in loss
of power and possible tool damage. Re-
fer 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 exten-
sion cord for more than one tool, add the
nameplate amperes and use the sum to
determine the required minimum wire size.
READ AND SAVE ALL INSTRUCTIONS FOR FUTURE USE.
Guidelines for Using Extension Cords
• If you are using an extension cord out-
doors, be sure it is marked with the
suffix "W-A" ("W" in Canada) to indi-
cate that it is acceptable for outdoor
use.
• Be sure your extension cord is prop-
erly 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.
