I overworked my Makita 4-1/2″ angle grinder and let the smoke out. I let it cool down, but it makes bad sounds and runs slow if at all. I called the Makita service center and they said the basic inspection was free, but if the electrics were toast, it was unlikely that it could be fixed.

When I turn my Erbauer 230mm 110v Angle Grinder on, the motor powers up, the gears turn and it all seems to work fine. After about 10-15 seconds it starts to smoke, but with no strange noise, and not any smell of burning. I’ve checked the brushes and they’re fine, and there doesn’t appear to be any incorrect wiring, or any foreign matter inside it.
