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.
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.
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.)
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.)
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.
