IMPORTANT WARNINGS FOR STRING TRIMMERS

2.Keep the cutting line trimmed to the proper length (done automatically by the appliance). Make sure that the guard is firmly in place, in working order and positioned between yourself and the cutting line.

Polarized connections will fit together only one way. Make sure that the receptacle end of the extension cord has large and small blade slot widths. If the plug does not fit fully into the extension cord, reverse the plug. If it still does not fit, obtain a suitable extension cord. If the extension cord does not fit fully into the outlet, contact a qualified electrician to install the proper outlet. Do not change the tool plug or extension cord in any way.
