TEST STITCHING Starting Sewing 1. Insert the fabric under the toe of the foot. (It is not necessary to raise the foot.) 2. Turn the handwheel gently toward you a couple of turns and check the thread chain. Then start sewing slowly. The fabric will be automatically fed. Guide the fabric in the desired direction. * For heavyweight fabric, raise the presser foot and insert the fabric in front of the knife. Then lower the foot and start to sew while guiding the fabric. 1 2 Finishing Sewing 1.
Securing Ends To avoid unravelling, it is necessary to leave a thread chain about 5 cm (2´´) long at the beginning and at the end of a seam. To secure the beginning and end of a seam choose one of the following methods. B A At the beginning A. Separate the end of the threads and knot them. B. Thread the chain through a large eyed needle, and weave the chain through the overlock stitches on the fabric. C. Cut the chain at the edge of the fabric.
Thread Tension (4 threads) Correct tension The illustration at left shows sewing results with correct tension settings. However, adjusting the thread tension may be required depending upon the type of fabric and thread being used. 1 2 4 5 3 6 Right side of fabric Right needle thread Left needle thread Upper looper thread Lower looper thread * Set all four thread tension dials at “3”. Then sew, and check the thread tensions.
Looper thread tension is out of balance (1) The illustration shows sewing results when the lower looper thread tension is too tight and/or upper looper thread tension is too loose. 5 1 6 65 10 98 7 98 7 4 65 10 98 7 98 7 3 432 10 65 432 2 Remedy: Loosen lower looper thread tension and/or tighten upper looper thread tension.
Threading the Machine (3 threads) Using the needle on the right only (for regular three-thread serging) Turn off the power switch and unplug the machine. Remove the needle and the thread on the left. Then retighten the needle clamp screw on the left to prevent losing the screw. 2 1 1 Needle on the right 2 Needle clamp screw on the left Using the needle on the left only (for wide three-thread serging) Turn off the power switch and unplug the machine. Remove the needle and the thread on the right.
Thread Tension (3 threads) Correct tension 4 1 The illustration at left shows sewing results with correct tension settings. However, adjusting the thread tension may be required depending on the type of fabric and thread being used. 5 1 2 3 4 5 2 3 * Set all three thread tension dials at “3”. Then sew, and check the tension balance. If the tension balance on the test piece is not satisfactory, you can adjust the thread tension with thread tension dial.
