PREPARATION FOR THREADING THREAD GUIDE POLE Pull up thread guide pole to the highest point until you hear it click. Place thread spools on pins and draw thread through thread guides on the pole from rear to front. Thread guide of pole can hold thread spools on the spool stand by pulling down the pole as illustrated.
SPOOL CAPS FOR DOMESTIC TYPE SPOOLS SPOOL DISC AND SPOOL HOLDERS FOR CONE SPOOLS For large cone spools use the rubber spool holders with the wide end at the top, and for small ones, use the same rubber spool holders but with the narrow end at the top. SPOOL NETS Polyester or bulky nylon threads become loose while unwinding. To keep consistent feeding of such threads, utilize spool net sleeving over the spool.
LINT TRAY With the lint tray located in this position, it will collect all your waste material. After completion of work if you then turn tray upwards in direction shown, finger Ref C will locate in slot D and left hand pin will slide into lower hole B. CUTTING WIDTH GAUGE When using cutting width gauge, the fabric is cut down and sewn at same distance from the edge of fabric. Within the distance of the width adjusted. THREAD CUTTER (Model 320 only) Thread cutter is built in needle plate.
CHANGING NEEDLE Raise needle bar to its highest point by turning hand wheel towards you, but leave presser foot down. Loosen needle clamp screw to remove the needle, and place new needle with Flat Side Away From you, into the needle bar as far as it will go, and tighten screw. NEEDLE, THREAD AND FABRIC CHART Use HA ×1 SP, HA ×1 (130/705H) Needles.
2. STARTING TO SEW THREADING YOUR MACHINE THREADING LOWER LOOPER Wrong threading may cause shipped stitches, 1. Feed the thread through the thread breaking threads, or other problems. Try to master the correct threading before moving on to test sewing. Threading must be carried out in the sequence of Lower Looper – Upper Looper – Needle. Open the front cover and the working table. Raise needle to its highest point by turning hand wheel towards you, and raise the presser foot.
THREADING UPPER LOOPER 1. Feed the thread through the thread guide as illustrated. 2. Pull the upper thread through the slot, holding the thread with your left hand. 3. Draw the thread through the thread guide as illustrated. 4.
THREADING NEEDLES 1. Feed the thread through the thread guide as illustrated. 2. Draw the needle threads through left-hand tension slot. Holding the thread with your left hand, pull down with right hand firmly. 3. Draw the thread through the thread guide as illustrated. 4.
HELPFUL HINTS REPLACING THREAD SPOOLS When replacing thread spools, the following steps may be helpful for quick changeover. 1. Cut off existing threads near the spools. Tie the cut ends thread from new spools as illustrated (seamen’s knot). 2. Raise presser foot. 3. Lower needle bar to its lowest position by turning hand wheel away from you. Carefully pull the existing threads until the connecting knots pass through needle eye and looper eyes.
TESTING STITCH OVERLOCK STITCHES After threading is completed, use a scrap of fabric that you plan to sew and test to sew in the following order. 1. Gently pulling all the threads to the left, lower the presser foot. Rotate the hand wheel towards you a few times to see if the lock stitches are properly formed. 2. Start the machine at low speed and feed in test fabric under the presser foot by slightly pushing it forward. (This can be done with the presser foot down on most fabrics except bulky materials.

THREE-THREAD OVERLOCK WITH ONE NEEDLE By threading the LEFT needle only a width of 6 mm will be produced and by threading the RIGHT needle only a width of 3.8 mm will be produced. Please keep the unused needle on the needle pad as illustrated. CONVERTING TO TWO-THREAD USE (Model 320 only) To convert to two thread use, first open the front cover and working table and raise needle to its highest point by turning hand wheel towards you. Remove the right needle and use the left needle.
NARROW AND ROLLED HEM, PICOT STITCH Narrow and rolled edge is ideal for use on thin materials such as georgette crepe, crepe de chine, silk etc. Also, picot stitch can be produced particularly when sewing on fine ‘scarflike’ materials. In view of the nature of these hems, they are unsuitable for use on ‘hard’ or ‘heavy’ materials. 1. Raise the presser foot. 2. Open the front cover and working table. 3.
ADJUSTING THREAD TENSIONS Turning tension dial to a higher number gives a tighter thread tension. Turning tension dial to a lower number gives a looser thread tension. The higher the number, the tighter the tension. Test each thread tension on a scrap of the fabric you plan to use.
ADJUSTING STITCH LENGTH ADJUSTING OVEREDGE CUTTING WIDTH Turn the stitch length dial until the Overedge cutting width can be adjusted from 4 to 7 required length is indicated. mm by simply turning overedge cutting width dial The higher the number, the longer according to the kind of fabric. the stitch. This dial can adjust the It is set at standard width of 6 mm when delivered stitch length from 1 to 5 mm. from the factory. Turn it towards “5” if fabric edge curls while sewing.( Fig.
DIFFERENTIAL FEED The differential feed has two independent feed dogs, one front (A) and one rear (B). Each feed dog has an individual feed mechanism which enables the feeding of material at a different ratio. POSITIVE DIFFERENTIAL FEED WHEN SET FOR POSTITVE DIFFERENTIAL FEED, the front feed dog (A) makes a longer stroke than the rear feed dog (B). This has the effect of accumulating material under the presser foot to offset the wavering on the fabric.
SETTING DIFFERENTIAL FEED Set by simply turning the differential feed control dial in the direction desired referring to the chart below. The adjustment can be made between 0.7 (negative effect) and 2 (Positive effect). These settings give the best ratio of feeding. For normal sewing, the dial should be set at 1. The dial can be reset even while sewing.
BASIC TECHNIQUES TURNING OUTSIDE CORNERS WITHOUT CUTTING THREADS 1. When you reach the fabric edge, stop stitching with the needle above the fabric. 2. Raise the presser foot and gently pull on the thread chain just enough to clear the stitch finger. 3. Turn the fabric, lower the presser foot and begin stitching in the new direction. Fig. 1. NOTE: When overlocking and trimming at the same time, cut the fabric along the new stitching line for about 3 cm, before turning the fabric. Fig. 2.
CORDED OVERLOCK, Corded overlock can be used to strengthen shoulder, sleeve or side seams when joining or making up knitted garments. As a decorative feature you can use knitting yarn of contrasting colours to further enhance your garment. Your machine is equipped with a presser foot which has been designed to feed your cord or yarn to the left of the safety stitch or to the right. Follow instructions as follows: 1. Snap the detachable cord guide, in your accessory set onto the thread guide pole (Fig.1). 2.
DECORATIVE EFFECTS In addition to normal overlocking which is fully described in this instruction book, your machine can also be used for a number of decorative applications such as decorative top-stitching, butted seams ,pin-tucking or making lengths of decorative braid. See below. Decorative top-stitching-using only two threads or using three threads (flat seam) Fold fabric along the line to be top-stitched and sew over the folded edge, making sure not to cut into the fold. Fig. A.
DIFFERENTIAL FEED APPLICATIONS Please refer to pages 19,20 DIFFERENTIAL FEED, Differential feed is designed to minimize puckering and wavering. It is also very effective for gathering. 1. Puckering Puckering tends to occur on woven or sheer fabrics. To obtain pucker-free seams, set the differential feed control dial at less than 1. 2. Wavering Wavering tends to occur on knitted or stretchable fabrics. To obtain waver-free seams, set the differential feed control dial at more than 1. 3.
3. CARING FOR YOUR MACHINE REPLACING MOVING CUTTER Replace a moving cutter if it becomes blunt as follows. A spare cutter will be found in your accessories. NOTE:You should not need to replace fixed cutter, which is made of special hard alloy material. FIRST REMOVE THE POWER PLUG FROM THE SUPPLY SOCKET-OUTLET. 1.
