Miter saw motor slowing down

posted by kcwood on Mar 29, 2008


Brushes are about 5/8 long, however the motor will not go to full speed, it seems like 1/2 speed. there is a pretty good arc coming from the brushes. The brushes do not seem to be wearing any, and there is no burn or hot smell coming from the motor even after continued use.
