Extension cords
In the event of a malfunction or breakdown, grounding provides a path of least resistance for
electric current and reduces the risk of electrical shock. Tools equipped with an electrical cord
having an equipment-grounding conductor 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 in any way. If the plug does not fit the outlet, have the proper
outlet installed by a qualified electrician.
The use of any extension cord will cause some loss of power. To keep this to a minimum and to
prevent overheating and motor burned-out; use the table below to determine the minimum wire
size (A .W .G.) of extension cord.
Use only three (3) wire extension cords that have three (3) prong grounding plugs, and three (3)
pole receptacles that accept the tool’s plug.
