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. _E**%^?J(&83%J7'3%,89%I'$7*$1`
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. _E**%^?J(&83%J7'3%,89%I'$7*$1`
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.

1. Grounded tools require a 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. _E**%G,+7*%F1`
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. _E**%G,+7*%F1`
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. _E**%G,+7*%F1`
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. _E**%G,+7*%F1`
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.
