1250W Electric Polisher Restoration | Dewalt dwp849x

I bought this power tool from Japan recycle container. It is 120V 1250W electric car polisher by Dewalt. It looks good, but it doesn't work anymore. There are a few of checkpoints to fix it, such as carbon brushes, power cords, power switches, armature and fields.
