15. Use proper size and type extension cord. If an extension cord is required,
it must be of the proper size and type to supply the correct current to the tool
without heating up. Otherwise, the extension cord could melt and catch fire, or
cause electrical damage to the tool. This tool requires use of an extension
cord of 0 to 10 amps capability (up to 50 feet), with wire size rated at 18
AWG. Longer extension cords require larger size wire. If you are using the
tool outdoors, use an extension cord rated for outdoor use. (Signified by "WA"
