12. CHAINING OFF AND TEST SEWING * When the machine is completely threaded, bring all of the threads over the throat plate and slightly to the left under the presser foot. * Hold the threads and apply a slight tension. * Turn the hand wheel toward you 2 or 3 complete turns to start the thread chain.
13. BASIC STITCH TYPES • 4 THREAD OVERLOCK MOCK SAFETY STITCH * This machine is a four-thread overlock that uses two needles and two loopers to create a 5.7mm (7/32 inch) wide four-thread mock safety stitch. • WIDE 3 THREAD OVER LOCK STITCH * When the right needle is removed a wide 5.
• SUGGESTED TENSION SETTINGS FOR 4 THREAD OVERLOCK MOCK SAFETY STITCH Note: * These are suggested tension settings only. * Tension settings are effected by 1) Type and thickness of fabric 2) Needle .
• SUGGESTED TENSION SETTINGS FOR THE 3 THREAD OVER LOCK STITCH Note: * These are suggested tension settings only. * Tension settings are effected by 1) Type and thickness of fabric 2) Needle size 3) Size, type and fiber content of thread.
15. HOW TO CHANGE THREADS/TIE ON METHOD * To change thread type or color, clip thread near the spool. * Place new thread on stand. * Tie new thread and old thread ends together. * Clip thread tails to 2 3 cm (1 inch) length. If clipped too short, threads may come untied.
* Pull the threads through the machine one at a time. * If threads do not pull easily, check for tangles on thread guides or looping under thread stand. * When pulling thread through the needle, STOP when the knot is in front of the needle. * Cut the thread, and insert it through the needle.
• TO PLACE MOVABLE KNIFE IN WORKING POSITION * Open looper cover and push the movable knife holder to the right as far as it will go. * Turn the knob up and toward you until the knife clicks into the operating position. Caution: Always close looper cover before operating machine.
9. HOW TO ADJUST THE OVEREDGE SEAM WIDTH * The machine is set to sew the four-thread stitch and three-thread left needle position stitch at a width of 5.7mm (7/32 inch). * The machine is set to sew the three-thread right needle position stitch at a width of 3.
20. HOW TO SEW A ROLLED HEM * Rolled hemming is done by rolling and overedging the fabric edge. * Light weight fabrics such as lawn, you, organdy, crepe, etc. perform the best. * Rolled hemming is not suited for heavy or stiff fabrics. MACHINE SET UP Be sure the machine is disconnected from the power source.
• SUGGESTED TENSION SETTINGS FOR STANDARD ROLLED HEM * Always sew a test sample and adjust tension balance if neccessary. * Adjust tension balance the same as for a narrow three—thread overlock stitch (page 21). SUGGESTED TENSION SETTINGS FOR UPPER LOOPER THREAD WRAPPED ROLLED HEM For medium and heavy weight fabrics that are difficult to roll.
* When the needle thread is too loose — Turn the needle thread tension dial (green) to a higher number. * 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.
21. STITCH VARIATIONS AND SEWING TECHNIQUES • HOW TO SEW A FLATLOCK DECORATIVE SEAM * A flatlock stitch is achieved by adjusting the tension of the three-thread overlock stitch, sewing the seam and pulling the fabric apart to flatten the seam. * The flatlock stitch can be used as a construction and decorative stitch or for ornamentation only.
* Pull on opposite sides of the seam to pull the stitches flat. (3) Decorative Flatlocking * Place the movable uper knife in the nonworking position (page 23). The fabric is not trimmed on this stitch. * Fold fabric wrong sides together. * Position the fabric so the seam is sewn with part of the stitch extending off the fabric.
• HOW TO SEW AN OVER LOCK 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.
* Fold the fabric with the wrong sides together and 32 sew. * Press the pin tucks in the same direction. • TURNING SQUARE CORNERS (1) Outside Corner * Cut out approximately 2 cm (51/64 inch) from the corner, in line with the overedge seam edge. * Sew one stitch beyond point (A) and stop.
* Place movable upper knife in nonoperating posi tion (page 23). Stitch on cut edge of fabric. Stop sewing before you reach the corner and fold the fabric to the left to straighten the corner. * Continue to sew slowly holding the fabric edge in a straight line moving the fold as you sew.
• APPLYING ELASTIC * Place the movable upper knife in the nonoperat ing position. (page 23) * Divide the elastic and the area where the elastic will be attached into quarters and mark with a watersoluble marker. * Lay elastic on the wrong side of the fabric making sure elastic and fabric edges are even.
• BRAIDiNG BY CHAINING OFF * Place the movable upper knife in nonoperating position. * Insert filler cord such as yarn or twill tape through the hole in the front of the foot. * Position the filler cord under the foot and chain off the desired length.
DIFFERENTIAL FEED (with differential feed machine only) * Differential feed is a system which “stretches” or “gathers” the fabric, when amount of feed of front feed dog in relation to the rear feed dog is changed. * The differential feed ratio ranges from 1:0.
(2) Stretch overedge (Use regular or rolled hemming throat plate) * Stretch overedge is ideal for sewing decorative collars, sleeves, skirt hems, etc. on loosely knit and woven fabrics. To set the differential feed adjusting lever * Open looper cover and loosen differential feed adjusting lever thumb screw.
22. HOW TO ADJUST THE PRESSER FOOT PRESSURE * The presser foot pressure of the machine is pre adjusted for sewing medium weight fabrics. * It may be necessary to adjust the pressure to sew different weights of fabrics by turning the pressure regulating screw.
