Extension Cords - Milwaukee 5337-20, 5337-21 Manual Del Operador

grounding
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.
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.
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.
Warning

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 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.
