[. . . ] If the tension on only one of the threads is set incorrectly, the resulting seam will be untidy. The stitches lie flat on the material, seams are not formed and the material is not drawn through. ³ a) Setting the upper thread tension You can use the thumbwheel for the upper thread tension to set the tightness of the upper thread. - too tight (higher setting), then the upper thread is loose and the material is being 'sewed' with the lower thread only. - too loose (lower setting), then the lower thread is loose and the material is being 'sewed' with the upper thread only. The upper thread tension is normally set between 4 and 6. » b) Setting the lower thread tension You can turn the screw on the bobbin case to set the tightness of the lower thread. The lower thread tension has been set correctly if the bobbin case unwinds slowly and evenly ("Drop test"). 14 c) ³ · Setting the presser foot pressure Here you can set the pressure with which the material is pressed onto the stitch plate. · Using the little screwdriver supplied, loosen the screw at the top of the front cover. Now use the lever to set the presser foot pressure, for example "0" if no pressure is to be applied, for example for darning with freehand stitches "1" for light fabrics (curtains) "2" for average fabrics (normal) "3" for heavy fabrics. ¿ d) Stitch width Here you can set the width of seam for zigzag patterns. Select a stitch width from 0. . . 5 using the selector wheel (0 = narrow / 5 = wide) Important: If the twin needle has been inserted, the selector wheel should be set to "3" maximum. If a higher setting is selected, the twin needle will break! e) Stitch length Here you can set the speed at which the material is carried forward when sewing. Select a stitch length on the stitch length selector wheel (0 = short / 4 = long). 15 10. If two values are set for the stitch length, these are understood as "from . . . to . . . " values. g) Straight stitch This is the most frequently used type of stitch. A smaller size of stitch should be selected for sewing finer materials. h) Zigzag The zigzag stitch is universal.

Make the fold as wide as you want the finished seam to be: the bottom fold should be about 5 mm away. Use the blind hem foot. While sewing, check the seam width and needle setting, to ensure that the seam remains uniform. Sew the blind seam on the underside of the material, so that only the peak of the zigzag stitch pierces the outside of the material. When you have finished sewing, push the left of the material over to the right and smooth out. The seam is almost invisible! The table below shows the suggested settings for the various values, depending on the material used. 20 Material-Thread-Needle-Table Please refer to the details for the various materials.
