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
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.)
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.) 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.)
3. 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.)
