I've got a problem. I've got some long jobs. After about 2 hours of continuous run time, something smells of that metallic electric smell. Brushes, I'm thinking and maybe the Hitachi router. As a boy, if you ever had a slot car racing set, you know what I'm talking about.
I took the hitachi brushes out and examined them. They looked ok. They were just under a half inch long.
Should I put some oil on these brushes as a precaution? If so, what type? I can't find my manual, and I'm wondering if there is a regular maintenance requirement.
Thanks,
Dave
