I've been using our Powermatic 3520 lathe for 8 years or so. I have always had it set to the high speed range.
I was able with that setting to slow down to as low as 250 or so. Recently that changed. Now the slowest that it will spin at the high range is 700rpm or so.
Anyone have knowledge about this area on the PM? Also the red reset button on the control box on the back of the head does not seem to do anything now.
There are no instructions in the manual about that box, so it's a bit of a mystery to me.
Thanks.
