I’m having a problem with my Jet 14-40. I recently cut a large branch from an oak tree that shaded my garage where the lathe is. I live in California and we had some temperatures that hit around 100 degrees. I think I may have smocked the motor. It won’t run at full speed and will trip the breaker after about 1 min. I’m hoping it’s not the motor .It makes a sort of a grinding before it trips the breaker. Any thoughts?
