I just picked up a craftsman block grinder and realized it has two plugs one for the light and one to run the grinder. The light plug is wired on 120 and the grinder plug is 240. When I found the manual on vintage machinery it appears like it’s only a single cord. I’m new to wiringso I just want to know if this is normal and if I will be able to switch it back to 120 fairly easily and if so what materials will I need.
