Hello, I am hoping someone can help me out with what I thought would have been a simple internet search...
 
	I am looking to purchase a used Juki DDL-555-4 industrial sewing machine.  When I asked if it was operational, they said it was missing the plug. When they sent the picture, it had 4 wires.  Do these sewing machines need a 4 wire plug like a dryer would have?  If so what kind of plug do I get?
 
	Thank you for any help
