Jet Jointer 6-inch won't run
I have had this model JJ-6CSX for a long time and get good results. Recently, I replaced the knives, and today I spent time getting heights adjusted. I then ran the face of a "stud" 2x4 over it, and the result is fab - smooth as a baby's bottom. Later, I came back to joint the edge of the same board. Jointer won't run - tripping circuit breakers. I saw other posts about changing a starting capacitor, but rotating my cutterhead manually (motor unplugged) I can feel it binding. What have I done ?!?!?!?
