Never had this happen before, in many years of running saws. 290 Stihl with 20" bar. One year old, not used hard. Chain is in good condition and was adjusted correctly, with plenty of bar oil.
Had just finished cutting down a 12" dead locust when the chain locked up on the bar. Checked all the normal causes and could not get it unlocked.
Took the chain off the bar and the nose sprocket would not turn. Took a firm rap on the handle of a screwdriver, with the blade resting on a sprocket tooth, to break it loose. Sprocket spun freely soon as it came loose.
Is there something going on here with bearings/bushings or whatever, that is going to cause me problems down the road? I did not think that wood chips stuck in the sprocket area would cause this.
