Buttonholes Mechanism rarely breaks down, usually due to a long period of time it is difficult to move, sometimes it can be completely unusable due to the inability to move.
This problem arises due to difficult access for lubrication and old dry grease deposits, video shows you how to get it back to normal.
This is a nice easy exercise for future young sewing machine repairers 🙂
