23. HOW TO SEW A COVER STITCH This machine can produce a 3-thread 5.6 mm wide bottom cover stitch. The cover stitch can be used for covering, binding or top-stitching necklines and for hemming the bottom, of T-shirts and sweat suits, etc. in addition to flat joining seams (plain seaming). The cover stitch is most suitable for stretchy fabrics such as knit.
Additional Information About Cover Stitch Start and end of sewing Note: Follow the instructions given below when sewing cover stitches because chaining-off at the end of sewing is not possible. At start of sewing Raise presser foot by lowering the presser bar lifter. Place material under presser foot behind the needle. Lower presser foot by raising the presser bar lifter. Note: When you start to sew from the middle of the fabric, place the fabric at the desired starting point of sewing.

3-Thread Cover Stitch Suggested Tension Settings ATD:J Tension is automatically set when seiecting the desired stitch type with the Auto Tension Dial (ATD).
Securing the seam end Since the seams formed by cover stitch unravel when the looper thread is pulled out at the end of sewing, secure the seam end in the following manner. When sewing through to the edge of fabric, among the threads coming out of the fabric edge, knot the needle threads (2 or 3 threads) together first, as shown on the illustration. Then, tie these threads with the looper threads.
24. HOW TO SEW A ROLLED HEM This machine can sew four types of rolled hems. Rolled hemming is done by rolling and overedging the fabric edge. Light weight fabrics such as lawn, voile, organdy, crepe, etc. perform the best. Rolled hemming is not suited for heavy or stiff fabrics. NOTE: Rolled hemming can only be performed with the overedge right needle. Machine Set up Caution: Be sure to turn off power switch. R Remove the overedge left needle, chain stitch needle and cover stitch needle(s).
Note: For a beautiful rolled hem thread the upper looper with wooly nylon and the needle and lower looper with lightweight regular thread.

Additional Information About Rolled Hemming Hold the thread chain when you begin sewing to keep it from curling into the seam. Place a slight tension on the material in the sewing direction and a finer seam finish can be obtained. The minimum overedge stitch width that can be obtained for rolled hemming is approximately 1.5 mm (1/16 inch) since the cutting width cannot be set below 3.5 mm (9/64 inch). To Secure the Rolled Hem Thread Chain Apply a small drop of liquid seam sealant to the end of the seam.
25. STITCH VARIATIONS AND SEWING TECHNIQUES How to Sew a Flatlock Decorative Seam A flatlock stitch is achieved by adjusting the tension of the 2-thread or 3-thread overlock stitch, sewing the seam, and then pulling the fabric apart to flatten the seam. The flatlock stitch can be used as a construction and decorative stitch or for ornamentation only. 1) Machine Set Up Use either overedge right needle or overedge left needle.
(3) Decorative Flatlocking Place the movable upper knife in the nonworking position (page 35). The fabric is not trimmed on this stitch. 1 2 Fold fabric wrong sides together. Position the fabric so the seam is sewn with part of the stitch extending off the fabric. Pull on opposite sides of the stitch to flatten. (4) Additional Information About Flatlocking The tensions must be correctly fine tuned for the fabric to pull flat. The upper looper thread is the prominent thread in the flatlock stitch.
How to Sew an Overlock Blind Hem The excess fabric is trimmed and the hem is sewn and the raw edges are overlocked in one operation. The overlock blind hem is best suited for sewing knit wear. It provides a durable finish that is almost invisible. Use overedge right needle and adjust machine for a narrow 3-thread overlock stitch. (See page 43) Note: The three-thread flatlock stitch can also be used.
Fold the fabric with the wrong sides together and sew. Press the pin tucks in the same direction. Turning Square Corners (1) Outside Corner Cutting line Cut out approximately 2cm (51/64 inch) from the corner, in line with the overedge seam edge. A Sew one stitch beyond point (A) and stop. 2 cm Raise needle and presser foot. 2 cm Pull the fabric to the rear of the machine just enough to release the thread caught on the finger of the needle plate. Note: Presser foot has been removed to show detail.
(2) Inside Corner Cut inside corner up to seam line as shown Seam line Cut Sew along seam line. Sew up to end of fold. (Leave needle in fabric) Raise presser foot. (Leave needle in fabric) Needle position Spread fold and re-fold so that seam line is straight. Seam line Pin Placement Insert pins to the left of the presser foot. The pins will be easy to remove and are away from the cutting action of the knives. Caution: Sewing over pins will damage and /or destroy the cutting edge of the knives.
How to Reinforce a Seam Inserting twill tape while overedge sewing will stabilize the seam. Insert the tape through the hole in the front of the foot. Position the tape under the foot to the back of the machine and sew the garment seam. The tape is attached as the seam is sewn. Braiding by Chaining off Place the movable upper knife in nonworking position. Insert filler cord such as yarn or twill type through the hole in the front of the foot.
26. MACHINE MAINTENANCE An overlock machine requires more maintenance than a conventional machine for two reasons: 1) A lot of lint is produced due to the cutting action of the knives. 2) An overlock runs at a very high speed and needs to be oiled frequently to lubricate the internal working parts. Cleaning the Machine Danger: Before cleaning your machine, disconnect power line plug from the wall receptacle. Clean the lint from the looper and knife area often with a dry lint brush.
How to Replace the Moveable Upper Knife Danger: Before replacing the moveable upper knife, disconnect power line plug from the wall receptacle. a b The moveable upper knife should be changed when it becomes dull. The moveable upper knife can be replaced according to the directions provided, however if there are any difficulties experienced, consult your Singer representative to make the replacement. 0.5~1mm c Be sure that the power line plug is disconnected from the electric source.
How to Exchange Light Bulb Danger: Always unplug before re-lamping. Light cover screw Light bulb is available at your Singer shop. Take old bulb to the Singer shop and ask for the same bulb. If voltage indicated on the electrical rating plate of your machine is 120V, ask for light bulb conforming to following specification.
27. OPTIONAL ACCESSORIES The following optional presser feet specially prepared for this machine are available at extra-charge. Note: Do not use presser foot made for other machines. Use of such presser foot may result in interference with the needle and knife and can be hazardous. A The snap-on type presser foot of this machine permits easy removal and replacement. C Caution: Be sure to disconnect the power line plug or turn off the power switch when changing the presser foot.
Optional Presser Feet 1) Elastic Foot This foot is used for attaching elastic tape to the garment and the amount of contraction of the elastic tape can be adjusted as required. 2) Blind Hem Foot This foot is for sewing cuffs on knit fabrics, skirt and trouser seams where seam should not be visible. 3) Shirring Foot This foot is most suited for gathering when sewing tiered skirts, yokes, cuffs and frills on skirts, etc.
