Sewing problems and their solutions
Problem/Cause Remedy
The machine skips stitches
The needle is not properly inserted. Push needle fully up. Flat side facing the back.
Wrong needle is in use. Use needle system 130/705 H.
Needle is bent or blunt. Insert a new needle.
The machine is not properly threaded. Check how the machine is threaded.
Needle is too small for thread. Use a larger needle.
Needle thread breaks
See reasons above. See above.
Thread tension is too tight. Adjust thread tension.
Thread is poor, has slubs in it or has become dry after
overlong storage.
Only use good quality threads.
Thread is too thick. Use needle with large eye (system 130 N).
Needle breaks off
Needle is not pushed completely in. Insert new needle and push completely in.
Needle is bent. Insert a new needle.
Needle is too thick or too thin. Change the needle.
Needle is bent, and has hit the needle plate because
you are pulling or pushing the fabric.
Only guide the fabric lightly.
The bobbin case is not properly inserted. When you insert the bobbin case, push it fully into the stop. Pull
lightly on the end of the thread to make sure bobbin case is secure.
The seam is sewn unevenly
The tension needs adjusting. Check needle thread tension.
Thread is too thick, stubbed or hard. Only use good quality threads.
The bobbin thread is unevenly wound. Do not wind thread by hand. Make sure thread is pulled solidly into
bobbin tension spring. Check bobbin threading path.
Thread loops at top or underside of fabric
Re-thread machine, making sure the presser foot is raised to its
highest position as you thread. This ensures that the needle thread is
securely in thread tension system.
