GROUNDING
TO PREVENT
ELECTRIC SHOCK
AND DEATH FROM INCORRECT
GROUNDING WIRE
CONNECTION:
Check with a qualied 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 t
the outlet, have a proper outlet
installed by a qualied
electrician.
Grounded Tools: Tools with Three
Prong Plugs
3-Prong Plug and Outlet
Tools marked with “Grounding Required” 1.
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.)
The grounding prong in the plug is 2.
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.)
The tool must be plugged into an 3.
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
Grounded1. 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 2.
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.)
The smaller the gauge number of the 3.
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.)
When using more than one extension 4.
cord to make up the total length, make
sure each cord contains at least the
minimum wire size required.
(See Table A.)
