Q
What do I do if my machine is acting nosier than usual?
A
The cause of your machine's irregular noise might be that the sewing machine is threaded improperly. Consult your sewing machine user manual for correct threading.
A damaged needle may also be the cause of your noisy machine - if needed insert a new needle.
If you are unable to figure out the cause of the noise have the sewing machine checked out by a professional.
