Hi.  
	 
 
	I just purchased a commercial sewing machine it is an Aisin AD3310.  
	 
 
	I got a crazy question for you. Is it possible to sew in “reverse” on this machine? I thought in order to lock stitch you have to. If you look at the picture of my machine, is it missing a lever to engage “reverse?”  If so, can I use a reverse polarity switch to reverse? Or can I get a part from a Toyota machine?
 
	 
 
	any thoughts would help!
 
	 
 
	thanks!!
