How can I keep my Dremel from overheating?
I've had my Dremel 4000 for over a year, and I've never had trouble with it. Recently though, I've noticed that the tool gets very hot after only a few minutes of use, and sometimes there is a faint burning smell. It functions well enough before it gets hot, and I don't hear any grinding when it is running. Any insight is appreciated.
Is this a good question?
