	Check the amp setting on the overload relay.
Dovetailer frequently trips.	Match the full load amps on the motor as noted on
	the motor plate. If amp setting is correct then there
	is probably a loose electrical lead or a failed
	component. See below.

	motor at 220+/-20. If incoming voltage is incorrect,
	you have a power supply problem. If voltage
	between starter and motor is incorrect, you have a

	motor is correct, you have a motor problem.
	If electric motor is suspect, you have two options:
Motor failure.	Have a qualified electrician test the motor for
