EXTENSION CORD CAUTION

When using a power tool at a considerable distance from a power
source, be sure to use an extension cord that has the capacity to
handle the current the tool will draw. An undersized cord will cause
a drop in line voltage, resulting in overheating and loss of power.
Use the chart to determine the minimum wire size required in an
extension cord. Only round jacketed cords should be used.

When working with a tool outdoors, use an extension cord that is
designed for outside use. This is indicated by the letters "WA" on
the cord's jacket.

Before using any extension cord, inspect it for loose or exposed
wires and cut or worn insulation.

tools, or other obstructions while you are working with a power
tool.
