Hi,
I have a dewalt 7" angle grinder, model 28494. When I pull the trigger it works but it is shooting a lot of sparks from where the brushes are. I took it apart and looks like some of the plastic on the armature and field has melted and there is a bunch of plastic shavings in the case, not sure where they came from because I don't see any parts worn down. Could a new set of brushes fix this or because the armature and field look like they got heated up do you think they also need to be replaced? The armature is 90 bucks so don't think I would replace that, will try brushes but don't want to stick parts into it if you think it's going to need new armature. They are about 170 new and this one is pretty new so I wouldn't mind sticking a little money into it but don't want to stick a lot into it, would just get a new one.
Thanks for any help
