3. PREPARATION FOR SEWING 3-1. ConneCting Power Cord Connect foot control and power cord ® Before plugging in your machine, be sure that the voltage is same as that of your machine. (written on a plate at back of machrne). ± Specifications vary from country to country.
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 (1) Cut the thread in use near the cone spool (behind the telescopic thread stand).
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 Replace needle in the following way: Note: be sure to take out the power supply plug before replacing 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.
(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 ©-.
(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. 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.
(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.

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.
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.
8. CORDED OVERLOCK Corded overlock can be used tc strengthen and stabilize stitches when joining elastic materials such as knitted fabrics. There are two ways of corded overlock. (1) Place the narrow cord (about 3mm) into the hole in the foot and back under the foot, then sew with the right needle stitching through the cord.
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.
11. ROLLED EDGE Rolled edge is achieved by rolling the fabric and 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.
13. REPLACING LOWER CUTTER Replacing Lower Cutter * Unplug the machine (1) Open front cover and disengage upper cutter. (‘See page 3) (2) Loosen lower cutter clamp screw®and remove lower cutter.
