Report "I have a Dremel Model 800 cordless rotary tool 10.8V. While using it one day to sand a small piece of wood, it felt extremely hot to the touch. I turned it off for an hour and when I went to turn it back on it ran at the highest speed. No matter if I start at one on the rotary dial or go all the way to ten, the speed is at top level. Also the 3 red battery indicator lights do not work at all. Is there any fix for this I can do myself. I really can't afford taking it to a repair shop right now, not that I know how much it would cost to repair or if it is even worth it. Can you please help me, thanks"
