I recently bought a 37-280, 6 inch jointer. It does not get up to speed and has no power when the belt is attached. It runs with out the belt on. I changed capacitor and cleaned the relay. the rely seems to be making contact so i dont think it is the relay. Would the motor be toast? I would not think so since the unit has a built in breaker so when over loaded it trips. Anyone have any suggestions what the problem could be?
