Trouble shooting Problem: 1. The machine skips stitches. The needle ist not inserted properly. The wrong needle is inserted. The needle is bent or blunt. The machine ist not correctly theaded. The needle is too fine for the thread. 2. The needle thread breaks Due to the above reasons. When the thread tension is too tight. When the thread quality is poor or slubbed. or when the thread has become too dry due to being in storage too long. When the thread is too thick. Solution: Push the needle up as far as it will go. With the flat side facing the rear. Insert needle system 130/705 H. Insert a new needle. Check the correct threading of the machine. Insert a thicker needle. See above. Adjust the thread tension. Only use high quality thread. Insert a needle with a large eye (system 130 N). 3. The needle breaks The needle is not inserted as far as possible. The needle is bent. The needle is too thin or too thick. The needle is bent due to the fabric being pulled causing it to hit the needle plate. Only guide the workpiece lightly. The bobbin case is not inserted correctly. Insert the new needle as far as it will go. Insert a new needle. Observe the needle chart (page 59, 60). Allow the machine to feed the material alone. When inserting the bobbin case, push it into place as far as possible. 4. The seam is not regular The tension is poorly adjusted. The thread is too thick, slubbed or hard. The bobbin thread is wound unevenly. Thread loops above or below the stitch. Check the needle and bobbin thread tensions. Only use perfect thread. Do not wind the bobbin without allowing the thread to run through the bobbin winder tension. Thread the machine properly. Check the needle and bobbin thread tensions. 5. The machine does not feed or feeds unevenly Lint has collected between the teeth of the feed dog. Remove the needle plate and remove the lint with the brush. 6. The machine does not run easily. There are pieces of excess thread in the hook race. Remove the unwanted threads and place one drop of oil in the hook. Important notes: Before changing the presser foot or needle, the on/off switch must be switched off. The machine must not be operated Always switch off the on/off switch without a workpiece when when leaving the machine threaded. unattended, even for short periods. This is particularly important when children are in the vicinity. 64
