Securing the seam end 1 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. 2 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 right illustration. Then, tie these threads with the looper threads.
26. HOW TO SEW A ROLLED HEM 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 right needle. Machine Set up 1 Caution: Be sure to turn off power switch. R Remove the left needle, chain stitch needle and cover stitch needle(s). N 1 R 2 2 Move the rolled hem lever to setting R.

Additional Information About Rolled Hemming Hold the thread chain when you begin sewing to keep it from curling into the seam. Turn the differential feed to 0.8 or 0.6 to eliminate puckering of fine fabrics. 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.
27. 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. Machine Set Up Use either overedge right needle or left needle.
Decorative Flatlocking 1 1 Place the movable upper knife in the nonworking position (page 10). The fabric is not trimmed on this stitch. 1 2 2 Fold fabric wrong sides together. 2 Position the fabric so the seam is sewn with part of the stitch extending off the fabric. 3 Pull on opposite sides of the stitch to flatten. 3 Additional Information About Flatlocking The tensions must be correctly adjusted for the fabric to pull flat. When sewing with 3-Thread flatlock.
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. 1 The overlock blind hem is best suited for sewing knit wear. It provides a durable finish that is almost invisible. 1 Use right needle and adjust machine for a narrow 3-thread overlock stitch. (See page 42) Note: The three-thread flatlock stitch can also be used. (See page 43) 2 2 Set the stitch length dial at 4.
2 Fold the fabric with the wrong sides together. Sew with the stitches lying neatly on the edge of the fold. 3 Press the pin tucks in the same direction. 2 3 Turning Square Corners Outside Corner 1 1 Cut out approximately 2cm (51/64 inch) from the corner, in line with the overedge seam edge. Cutting line Sew one stitch beyond point (A) and stop. A Raise needle and presser foot.
Inside Corner 1 Cut inside corner up to seam line as shown 1 Seam line Cut 2 2 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. Lower presser foot. 3 3 Continue stitching on seam line. 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.
How to Reinforce a Seam Inserting twill tape while overedge sewing will stabilize the seam. 1 Insert the tape through the hole in the front of the foot. 1 2 Position the tape under the foot to the back of the machine and sew the garment seam. 2 3 3 The tape is attached as the seam is sewn. Braiding by Chaining off Place the movable upper knife in nonworking position. 1 Insert filler cord such as yarn or twill type through the hole in the front of the foot.
28. 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 The moveable knife should be changed when it becomes dull. b Be sure that the power line plug is disconnected from the electric source. 0.5~1mm The moveable knife can be replaced according to the directions provided, however if there are any difficulties experienced, consult your dealer to make the replacement.
How to Change Light Bulb 1 Danger: Always unplug before re-lamping. Light cover screw Light bulb is available at your local retailer. Take old bulb to the retailer and ask for same bulb. If voltage indicated on the electrical rating plate of your machine is 120V, ask for light bulb conforming to following specification.
29. SNAP ON PRESSER FOOT REMOVAL/ REPIACEMENT The following optional presser feet specially prepared for this machine are available at your local retailer. Note: Do not use presser feet made for other machines. Use of such presser feet may result in interference with the needle and knife and can be hazardous. The snap-on type presser foot of this machine permits easy removal and replacement.
30. OPTIONAL PRESSER FEET Elastic Foot This foot is used for attaching elastic tape to the garment while the amount of strech can be adjusted and remain uniform. Blindhem Foot This foot is for sewing cuffs on knit fabrics, skirt and trouser seams where seam should not be visible. Ruffling Foot This foot is most suited for gathering when sewing tiered skirts, yokes, cuffs and frills on skirts, etc. This foot is also suited for sewing two fabrics together and gathering the bottom fabric in one operation.
31. TROUBLESHOOTING CHART Problem Solution Page Fabric does not feed well - Lengthen stitch length. - Increase presser foot pressure for heavy weight fabric. - Decrease presser foot pressure for lightweight fabric. 29 30 30 Needle breaks - Insert needle correctly. - Do not pull fabric while sewing. - Tighten needle set screw. - Use a larger needle on heavy fabrics. 13 33 13 13 Thread breaks - Check threading. - Check for tangled or caught thread. - Insert needle correctly.
