Welcome aboard Visteonguy. I haven't had this problem with my M12V, but I have had occation to talk to the folks at Hatachi about my router somr time back. I can tell you that they were really helpful and courtious to me.
I have had simular problems with drills and grinders though. Almost all of them had brushes that were sticking in the brush holder and/or a dirty commintator. A good cleaning fixed all of them except 1 or 2. If you do tackle this cleaning job, get a good electrical contact cleaner to clean it, should be available from any electrical supply. Good luck.....Chuck
