If so, great! Is it a very small little screw in the back?
I have put back the old regulator and now I was giving 229v. In case I have taken it to a technician. He has increased the rpm (it was slightly low) and explained that when they have been unemployed for a long time (in this case 8 months) they can be "polarized" (no idea of the subject) and after a while they adjust. Otherwise it is perfect. Just put new nafa.
So now I will see the little screw and I will have to fight it with the seller. I wanted to upload a photo but I don't know how.
Thank you, I comment.
