-17-
If an extension cord is
necessary, a cord with
adequate size conductors that is capable
of carrying the current necessary for your
tool must be used. This will prevent
excessive voltage drop, loss of power or
overheating. Grounded tools must use 3-
wire extension cords that have 3-prong plugs
and receptacles.
NOTE: The smaller the gauge number, the
heav i er the cord.
