⦁ is indicated when the red line on the tension adjustment wheel is in line with the marking A ⦁ the tension does not need adjusting for normal sewing work ⦁ for special sewing work, the tension can be adjusted to suit the fabric Perfect Stitch Formation ⦁ the interlooping of the threads is in the fabric Upper thread tension too tight ⦁ the lower thread is pulled more up, i.e. to the right side of the fabric ⦁ to reduce the upper thread tension turn tension adjustment wheel to 3-1 Upper thread tension too loose ⦁ the upper thread is pulled more down, i.e. to the wrong side of the fabric ⦁ to increase the upper thread tension turn tension adjustment wheel to 5-10 Optimal upper thread tension is set in the factory. For this, Metrosene threads 100/2 weight (Mettler, Switzerland) are used in the bobbin and also in the upper thread. The tension may vary when using other types of thread such as embroidery thread, and it may therefore be necessary to adjust the tension to suit the fabric and stitch type. For example: Tension Needle Metallic thread approx. 3 90 Monofilament approx. 2-4 80 Stitch plate Stitch Plate Markings ⦁ the stitch plate is marked with vertical, horizontal and diagonal lines in mm and inches ⦁ the lines help to guide the fabric for sewing seams and precise topstitching, etc. ⦁ the horizontal markings are helpful for sewing corners and buttonholes, etc. ⦁ the diagonal markings are useful for quilting ⦁ the vertical measurements correspond to the distance between the needle and the line ⦁ needle insertion point is position «0» (center needle position) ⦁ the measurements are marked to the right and left, measuring from the center needle position Removing the Stitch Plate ⦁ raise the presser foot and needle ⦁ power switch to «0» (off) ⦁ press the stitch plate down at the right back corner B until it flips up ⦁ remove the stitch plate Replacing the Stitch Plate ⦁ place the stitch plate over the opening A and press down until it clicks into place A B A

so that the stitch patterns are sewn too close together or not close enough. This can be remedied with Balance to suit the fabric and produce perfect results. Normal position Denser stitch formation - pulling the stitch pattern closer together (shorter stitch length) Finer stitch formation - extending the stitch pattern (longer stitch length) Test-sewing When using decorative stitches, we recommend to test-sew the stitch pattern on a piece of the project fabric. If the balance has been adjusted, return it to the normal setting once sewing is completed!

Button depressed = feed-dog is lowered. █ for free-motion sewing (darning, embroidery, quilting, etc.) Pulling, pushing or holding back the fabric will result in uneven stitches. Let the fabric feed evenly. With each stitch the feed dog moves forward by one step. The length of this step is determined by the stitch length selected. With an extremely short stitch length, the steps are also very short. The fabric moves under the foot quite slowly, even at full sewing speed. e.g. buttonholes, satin stitch and decorative stitches are all sewn with a very short stitch length. Feed-dog drop Feed-dog and fabric feed

If the foot is at an angle, e.g. when sewing over thick to thin or vice-versa, the feed dog cannot grip and feed the fabric. The fabric might jam. To solve this problem, place one, two or three compensating plates as required behind the needle under the presser foot to level it. To correct the height in front of the foot, place one or more plates to the right of the foot close to the needle. Sew until the foot is level again and remove the plates. Height Compensation of Uneven Layers When sewing corners only a small section of the fabric is actually on the feed dog. Therefore it cannot grip the fabric well. Sewing Corners Correct this by placing one or more compensating plates as close as possible to the edge of the fabric.

The thread is chosen according to use. For a perfect sewing result, thread and fabric quality play an important role. It is recommended to use quality brands. Cotton thread ̶ cotton thread has the advantage of being a natural fiber and therefore is especially suitable for sewing cotton fabrics ̶ if cotton thread is mercerized, it has a slight sheen Polyester thread ̶ it has a high tensile strength and is particularly colorfast ̶ polyester thread is more flexible and is recommended where a strong and elastic seam is required Thread Needles, Threads Correct needle/thread combination When sewing, the thread should travel smoothly down the long groove on the front of the needle. Too thin thread or too thick needle The thread has too much clearance in the groove. Skipped stitches and damage to the thread can occur. Too thick thread or too fine needle The thread rubs on the edges of the groove and can get jammed. This can break the thread. Needle, Thread and Fabric Care must be taken when choosing needle and thread. The correct needle size depends on the selected thread and fabric. The fabric weight and type determine the thread weight, needle size and point form. WARNING! Checking the needle condition The needle condition should be checked and the needle replaced regularly. A defective needle not only damages the fabric but also the sewing computer. Follow these guidelines: Always replace the needle when starting a new sewing project.
