Many of the new fabrics made of synthetic blends tend to dull the needles more easily than fabrics made of natural fibers, . Before placing the material on the machine, see that the ends of the threads have been drawn about 3 -4 inches to the rear of the machine, Hold on to threads during the sewing of the first 3 or4 stitches of the seam. . Test the machine stitch on a scrap of fabric you plan to use, The fabric should be double thickness, Adjust the machine for the length of stitch and tension suitable to your fabric, . Fabric should be placed under the presser foot with the bulk of the material to the left of the needle and the right edge of the material placed on the 5/8" seam marking on the needle plate when making a simple seam. 5_ Run the machine at a slow even speed. The more pressure you put on the foot control, the faster the machine will sew. 6. Fasten each seam by back tacking at the beginning and end of the seam. 7. Always finish sewing each seam with the needle at its highest point. 8. Guide the fabric gently with your hand in front of the needle. Never pull or hold the fabric in such a way, that the normal feeding is altered. , When turning the hand wheel manually, always turn it toward you.
