3-2. Setting Telescopic Thread Stand Extend the telescopic thread stand to its full height, then turn it until the shaft clicks into its locked position. 3-3. Changing Threads The machine is supplied with thread but iiiy I au •.y spool (1) Cut the thread in use near the cone the Place (behind the telescopic thread stand). end the to new thread on the spindle and tie it of the original thread. presser (2) Raise the presser foot lifter to lift up the foot.
Cover the spool with the “NET” as needed to prevent thread from slipping down on thread cones. When using a standard type thread spool, insert the spooi adapter (supplied with the machine) (as shown). 3-4. Replacing Needle Clamp Scr Replace needle in the following way: Note: be sure to take out the power supply plug before replacing needle. (1) Bring needle to its highest position by turning handwheel towards you. (2) When replacing right needle, loosen right needle clamp screw and remove needle.
3-5. Threading When threading the machine from the beginning, threading must be carried out in the following sequence: First: Lower loopef threading (A) Second: Upper looper threading (B) Finally: Needle threading (C, D) (1) Lower looper threading (A) Open front cover. (See Page 2) Take the thread drawn from the spool and pass it, through guide © of the thread stand and then, in order, through guides ©— ©and thread tension dial ©. (Fig. A) Fig.
(2) Upper looper threading (B) Bring the upper looper to its lowest position by turning handwheel toward you. Draw thread from spool and pass it, through guide ( of the thread stand and then, in order, through guides ©-.Ø.(Fig. A) While pressing down the tension release lever with your right hand, lay thread between thread tension discs with your left hand. (Fig. B) Thread the hole of upper looper © using tweezers. Cut the thread leaving about 10cm (4”) of spare thread.(Fig. C) Close the front cover.
(3) Needle Threading (C) (D). For ease in threading, turn the moveable cutter to the non-operating position. (See Page 3). 1. Raise the needles to their highest position. 2. Draw thread from spool and pass it through guide ®. 3. Lay thread between thread tension discs © while pressing down the tension release lever. 4. Pass thread through guides ©, ®, © for right needle thread. Pass thread through guides ©, © for left needle thread. (Fig A) Fig. A 5. Then thread each needle’s eye ©.
4. FOUR THREAD OVERLOCK STITCH USING 2 NEEDLES 4-1. Before Sewing After threading is completed, and when the threads are not wound around the stitch finger, gently draw out the four threads under and behind the presser foot, and turn the handwheel towards you by hand two or three times to make stitch form on the stitch finger. 4-2. Setting the Fabric When beginning to sew, place the material just ahead of the presser foot and it will be fed through. There is no need to raise the presser foot lifter.
(2) Ending of sewing Sew off the material forming a chain to prevent the thread from untying and to prepare for the next sewing. — Draw the finished fabric gently backwards and to the left as the machine is operating and make chain-stitches. This is called chain-stitch sewing. Then cut the thread 5 6cm (2”) from the presser foot + Do not pull it out roughly as the needle will bend and break.

5. ADJUSTING BALANCE OF STITCH WIDTH AND CUTTING WIDTH • Adjust the cutting width from 5.2 (0.2”) to 7.0mm (0.28”) according to the kind of material. • The standard cutting width is 5.5mm (0.21 “). • Open the front cover to adjust the cutting width. (1) If the cutting width is narrower than the stitch width, leavinioops off the fabric edge, turn the cutting width adjusting dial to the direction of arrow.
7. DIFFERENTIAL FEED Differential feed prevents stretching or puckering fabrics, since two independent feed dogs, one in front and one behind the needles, can be adjusted to feed at different ratio. This function produces a neat finish of overlock for stretchable and lightweight fabrics. + “N” indicates the normal position. on a scrap of material you are going to use.

10. THREE THREAD OVERLOCK STITCH USING 1 NEEDLE Though this machine is made mainly for 4 thread stitch overlock using 2 needles. To sew three-thread stitch overlock using 1 needle simply remove 1 needle. (1) By removing the right needle. Three-thread overlock stitch using 1 needle for as wide as a 4-thread overlock stitch using 2 needles can be achieved. Use the left thread tension. (Dial ®).The cutting width is normally 6mm. The differential feed ratio is normally “N”. (See R16).
11. ROLLED EDGE Fine Rolled Edge / 4 The fabric is rolled by adjusting. The thread tension and is over locked with upper looper thread. The fabric is overlocked with upper and lower looper thread. Rolled edge is achieved by rolling the fabri c and 7. ideal for use with thin materials. (1) Remove the left needle. (Sew only with the right needle> (2) Pull stitch finger knob toward you to align it with front red line on needle plate.
12. PIN TUCKS Pin tucks are overlocked on the edge. So as to avoid cutting the fabric, raise the upper cutter. Pin tucking is suited to the design of a child’s clothing and a lady’s blouse. (1) Remove the left or right needle for your desired pintuck width. (Sew only with the one needle.) (2) Raise the upper cutter. (See P3) + Raise the presser foot lifter. (3)The tension is set for normal overlock. (See P12) + Mark and priin tucks in advnce + The differential feed ratio is normally “N’.’.
13. REPLACING LOWER CUTTER Replacing Lower Cutter F * Unplug the machine (1) Open front cover and disengage upper cutter. (‘See page 3) (2) Loosen lower cutter clamp screw®and remove lower cutter. (3) Set the new lower cutter. Align the top of lower cutter with the top of needle plate, and tighten lower cutter clamp screw a a 14.
