I was using the router the other day and it totally quit..... I put in new spare "carbon brushes" and everything was fine so I thought I needed new brushes. Today I put the old brushes back in and everything is fine. Do brushes get so hot that they shut down or something like that?? Can you file them flat on the ends to work? Was going to order some more but thinking I would ask here first. Probably should know this- But Don't!
-TIA
