Description of fault Possible cause Error elimination The display shows a message indicating the possible cause. The automate does not start up. Display: Info 200 Before sewing start the needle is in front of the wrong stitch or not in the position “up” respectively. Correct position: The needle is in front of the left stitch.
Description of fault Possible cause Error elimination Skipped stitches The material is not spread or spread too little. Check the spreading (see chapter “Spreading”). The matching needle size has to be chosen according to the material, the material thickness and the thread used. Change the needle size. (See Operating Instructions) Attention! After changing the needle size the distance needle-looper has to be checked. Throat plate, loopers or spreaders have possibly been damaged by the needle.
Description of fault Possible cause Error elimination Thread breakage Thread-guiding parts as e.g. thread pipes, thread guides or the rotary thread take-up disc have sharp edges. Check whether thread-guiding parts are sharp-edged. Check whether the throat plate, the loopers or the spreaders have been damaged by the needle.
