Can't find the answer to your question in the manual? You may find the answer to your question in the FAQs about the Singer Heavy Duty 4423 below.
Which size of needle you can best use depends on the thickness of the fabric you use. With a thick fabric you should use a thick needle. The packaging of your needle states for which substances your needle is suitable.
Generally, a sewing needle lasts about 7 to 9 hours.
There can be several causes for needle breakage: - Not using the right needle for the right fabric - The needle is set too low - The fabric is not properly guided - The bobbin case is not inserted correctly
Ensure that the needle is inserted correctly, threaded properly, and the presser foot is down.
Use the tension dial located on the front of the machine to increase or decrease the thread tension according to the fabric you are using.
Unscrew the needle clamp screw, remove the old needle, insert a new needle with the flat side facing the back, and tighten the needle clamp screw securely.
Check if the needle is inserted correctly and not bent, ensure that the thread is not tangled or caught in the bobbin area, and make sure all screws and parts are tightly secured.
Regularly clean the lint and dust from the feed dogs, bobbin case, and needle plate with a soft brush. Oil the machine's moving parts as indicated in the manual using a high-quality sewing machine oil to ensure smooth operation.
