Conclusion
It is essential to determine whether your sewing machine actually needs to be repaired '''***before'''*** you attempt disassembly or other repair actions.
''See attached instruction manuals and links to bench mark videos for information on how your machine should work.''
Many perfectly good sewing machines end up as unusable or are scrapped purely as a result of owner attempts at “repair” that are unnecessary.
Most problems that arise on domestic sewing machines - e.g. skipping stitches, puckering material, needle breakages, thread jams etc. etc. are a result of incorrect user actions.
