It seems inevitable to have more than a few glitches when sewing. One way we learn about the parts of a machine is by having to remedy sewing related problems yourself.
In fact many of the mistakes we make in sewing can be prevented with regular maintenance. But for those setbacks, a proper knowledge of your sewing machine will save time troubleshooting and fixing the problem."
Be meticulous with your maintenance to prevent any problems later on. Care for your machine and clean it regularly while keeping it free from dust and lint.
But when the going gets rough and the machine starts to grind and bang around, it may be time to get a professional to repair it.
Try oiling it but don’t be too eager to tighten/ loosen any bolts that may compromise the machine’s timing.
Keep vigilant and you’ll be able to troubleshoot anything that could lead to a future predicament.
