Length of Extension Cord Wire Size (A. W. G. ) Up to 25 16 26 to 50 14 51 to 100 12 When working with the 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 an extension cord, inspect it for loose or exposed wires and cut or worn insulation. ELECTRICAL CONNECTION Your grinder has a precision built electric motor. It should be connected to a power supply that is 120 volts, 60Hz, AC only (normal household current). Do not operate this tool on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat.
