Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension
cord or have it repaired by a qualified person before using it.
Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire and should be
protected with a 15 A time-delayed fuse. Before connecting the motor to the power line, make sure the switch
is in the OFF position and the electric current is rated the same as the current stamped on the motor nameplate.
Running at a lower voltage will damage the motor.
WARNING: This tool must be grounded while in use to protect the operator from electric shock.
