Question: Brushes

Yoni pena

How do I replace brushes on Dewalt model # D25550?
Hello,

I have a couple of D25550 / D25850 Demo Hammer which have the variable speed potentiometer damaged. Most probably its the concrete dust which blocks the internal contacts. I can clean them with electrical contact cleaner and they work but only for a few weeks and then they wont power on. I would like to bypass the variable speed control so they are always in high speed. What would be the best way of doing this?

Thanks.
