SAFETY GUIDELINES

BD4603

In the event of a malfunction or breakdown,
grounding provides a path of least resistance
for electric current to reduce the risk of ele­ctric shock. This tool is equipped with an electric
cord having an equipment-grounding conductor
and a grounding plug. The plug must be plugged
into a matching outlet that is properly installed
and grounded in accordance with all local codes
and ordinances.

Do not modify the plug provided. If it will not
fit the outlet, have the proper outlet installed
by a qualified electrician.

Improper connection of the equipment-grou
nding conductor can result in a risk of electric
shock. The conductor, with insulation having
an outer surface that is green with or without
yellow stripes, is the equipment-grounding
conductor. If repair or replacement of the ele­ctric cord or plug is necessary, do not connect
the equipment-grounding conductor to a live
terminal.

Check with a qualified electrician or service
personnel if the grounding instructions are

ELECTRICAL SAFETY

not completely understood, or if in doubt as
to whether the tool is properly grounded.

Use only three wire extension cords that have
three-prong grounding plugs and three-pole
receptacles that accept the tool’s plug.

Repair or replace a damaged or worn cord
immediately.

This tool is intended for use on a circuit that
has an outlet that looks the one illustrated in
Figure A below. The tool has a grounding plug
that looks like the grounding plug as illustra­ted in Figure A below. A temporary adapter,
which locks like the adapter as illustrated in
Figure B below, may be used to connect this
plug to a two-pole receptacle, as shown in Figure
B if a properly grounded outlet is not available.
The temporary adapter should only be used
until a properly grounded outlet can be installed
by a qualified electrician. The green colored
rigid ear or tab, extending from the adapter,
must be connected to a permanent ground
such as a properly grounded outlet box.

* Canadian electrical codes require extension
cords to be certified SJT type or better.
** Use of an adapter in Canada is not acceptable.
