Anybody have a copy of the J&S 540 manual they could share with me? I recently bought a 540 and have no idea what to do now that I have it in my shop. Never had a surface grinder before, just knew that I need one.
It is a 3 phase machine with the two round buttons. So I'm guessing that it has a "mag" starter switch. I was thinking that I could at least get it running to see if all is good with a VFD. But trouble with that is that you are supposed to control the 3 phase power with the VFD rather than the machine switch. So I would have to bypass the mag switch. Seems like that would be easy enough, but I'd like to see a wiring diagram before I open anything up and start guessing.
If I am able to get the motors running I still do not know for certain what the controls on the machine do. Again a manual would be best starting point.
One concern that I have is the lever on the right side, front of the panel. I think that it controls the forward/back motion. Someone has clobbered that up with a piece of stock hanging over the top with a spring holding the lever down. Obviously something is wrong with that.
If you could help me out with a manual I'd get you my email of address whatever is preferred.
Thank You,
Ron
Here is a picture from another thread. Someone else's machine but same as mine.
