EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool's plug. When using a power tool at a consid-
erable distance from the power source, use an
extension cord heavy enough to carry the current that
the tool will draw. An undersized extension cord wiJl
cause a drop in line voltage, resulting in a loss of
power and causing the motor to overheat. Use the
chart provided below to determine the minimum wire
size required in an extension cord. Only round jack-
eted cords listed by UndeP,vriter's Laboratories (UL)
should be used.
