Why servicing your machine is so important?
Bag sewing machines are made up of hundreds of moving parts. All the parts must move in synchronization with each other. All the parts need to be properly lubricated to keep it sewing. As recommended by the manufacturer, your machine must be serviced regularly. Failure of service and repair can eventually lead to premature wear of parts, misalignment of parts or failure of parts in the machine.

Improper stitch formation thread breaking, and needles breaking are signals that you need to get the machine in for service immediately.

A bent needle and incorrect threading can cause problems. If your machine is well maintained and serviced but doesn’t seem to stitch properly, try replacing the needle first and re thread the machine according the threading signal
