Thanks, Joe! I greased the motor and oiled everything else. I can't vouch for what any previous owner might have done, but I followed the rules! I will try contacting the seller to see if he/she knows much about the history of this machine and whether it was used recently or not.
One of the brush caps is broken, so I am going to wait until the new one arrives and then I'll remove the brushes and clean them and the tubes. Denatured alcohol, right?

Again, thanks.
