	shown in Fig. 6.
	The thermal protector operates to stop the motor

		specifications given on page 6, replace with an
		extension cord such as that shown on page 6. If
		the capacity of the power supply is insufficient,
		increase the power supply capacity to remove the
		cause of a flow of excessive current (over-current).
	(3)	Wait approximately 5 minutes, then press the
		reset switch of the thermal protector (Fig. 6).
