2022-05-18 The grease in the motor section (not shown) had solidified. THe grease was loosened with wd-40 then filled with blue bearing grease. It sounds like the bearing are bad but it works for now. I don't intend to use it for any serious work. Aditionally, the switch was broken and popped during the repair. It was replaced with a similar but higher rated switch. Its the olnly one I had.
