I am suspecting the brushes on the motor are worn out, but haven't been abl e to get the unit opened yet. There are about 11 screws holding the two ha lves of the case together. About 8 of the screws are deeply set into the ca se, and of course they are filled with 10+ years of accumulated dirt and de bris. I have been using a giant needle to clean out the dirt and debris so I can use an allen wrench to remove the screws and see what gives. Hopefu lly just brush replacement will be needed.
My question here is: Has anyone else experienced a similar problem and wha t did they find and how did they fix their machine?
Polite responses appreciated.
