Guidelines for Extension Cords
Use proper extension cord. Make sure your
extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersized
cord will cause a drop in line voltage, resulting in loss
of power and cause overheating. The table below
shows the correct size to use depending on cord
length and nameplate ampere rating. If in doubt, use
the next heavier gauge. The smaller the gauge
number, the heavier the cord.
Be sure your extension cord is properly wired and
in good operating condition. Always replace a
damaged extension cord or have it repaired by a
qualified person before using it.
Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.
In the event of a malfunction or breakdown,
grounding provides the path of least resistance for
electric current and reduces the risk of electric shock.
This tool is equipped with an electric cord that has an
equipment grounding conductor and a grounding plug.
The plug MUST be plugged into a matching
receptacle 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
receptacle, have the proper receptacle installed by
an electrician.
Improper connection of the equipment grounding
conductor can result in risk of electric shock. The
conductor with the green insulation (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 you do not completely understand the grounding
instructions, or if you are not sure the tool is properly
grounded.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool’s plug.
This tool is intended for use on a circuit that has a
receptacle like the one illustrated in Figure A, a
3-wire electrical plug and receptacle that has a
grounding conductor. If a properly grounded
receptacle is not available, an adapter, Figure B, can
be used to temporarily connect this plug to a
2-contact ungrounded receptacle. The adapter,
Figure B, has a rigid lug extending from it that MUST
be connected to a permanent earth ground, such as
a properly grounded receptacle box.
Repair or replace damaged or worn cord immediately.
