I want to change the upper knife on my AirThread 2000d. I cannot get it loose. Took to the local dealer. They were absolutely no help at all. Kept it for a week, supposedly took the knife off and put it back on. Said there were nicks in the knife. I NEVER sew with pins, so it must have come that way. Any hints on how to get the knife loose so I can change it?
