Grounding
TO PREVENT ELECTRIC SHOCK AND
DEATH FROM INCORRECT GROUNDING
WIRE CONNECTION:
Check with a qualified electrician if you
are in doubt as to whether the outlet is properly
grounded. Do not modify the power cord plug
provided with the tool. Never remove the grounding
prong from the plug. Do not use the tool if the
power cord or plug is damaged. If damaged, have it
repaired by a 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
3-Prong Plug and Outlet
1. Tools marked with “Grounding Required” have
a three wire cord and three prong grounding
plug. The plug must be connected to a properly
grounded outlet. 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.
(See 3-Prong Plug and Outlet.)
2. 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.
(See 3-Prong Plug and Outlet.)
3. The 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 the preceding illustration.
(See 3-Prong Plug and Outlet.)
Double Insulated Tools:
Tools with Two Prong Plugs
Outlets for 2-Prong Plug
1. 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.
2. Double insulated tools may be used in either of the
120 volt outlets shown in the preceding illustration.
(See Outlets for 2-Prong Plug.)
Extension Cords
1.
Grounded
tools require a three wire extension
cord.
Double Insulated
tools can use either
a two or three wire extension cord.
2. 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.
(See Table A on page 7.)
3. 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.
(See Table A.)
4. When using more than one extension cord
to make up the total length, make sure
each cord contains at least the minimum
wire size required.
(See Table A.)
5. 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 cord size.
(See Table A.)
6. If you are using an extension cord outdoors, make
sure it is marked with the suffix “W-A” (“W” in
Canada) to indicate it is acceptable for outdoor use.
7. Make sure the extension cord is properly wired
and in good electrical condition. Always replace
a damaged extension cord or have it repaired
by a qualified electrician before using it.
