Why does the needle thread keep breaking on my Silver 392 Sewing Machine?
The needle thread may break due to several reasons: * Improper threading of the needle thread. * Excessive needle thread tension. * A bent or blunt needle. * Incorrect needle insertion. * Failure to draw the fabric to the back after sewing. * Using thread that is too heavy or too fine for the needle.
Why is my Silver 392 Sewing Machine running noisy and not smoothly?
Your Silver Sewing Machine may not run smoothly and may be noisy because threads are caught in the hook mechanism or the feed dog is packed with lint.
