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.

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.

immediately.
Extension Cords
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 machine will draw. An undersized
cord will cause a drop in the line voltage
resulting in power loss and overheating. The
table following shows the correct size to use
depending on the cord length and nameplate
ampere rating. If in doubt, use the next heavier
gauge. Remember, the smaller the gauge
number, the heavier the cord.
