Place thread spools on pins and draw thread through thread guides on the pole from rear to front. Thread guide of pole can hold hread spools on the spool stand by pulling down the pole as illustrated.
Spool cap SPOOL CAPS FOR DOMESTIC TYPE Domestic cotton reel SPOOLS Cone type thread 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.
LINT TRAY With the lint tray located in this position it will collect all your waste materials. After completion of work, remove the lint tray. CUTTING WIDTH GAUGE When using cutting width gauge, the fabric is cut down and sewn at same distance from the edge of fabric.
CHANGING NEEDLE Needle clamp screw 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.
STARTING TO SEW THREADING YOUR MACHINE Wrong threading may cause shipped stitches, 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. Pass the thread through wire thread guide and looper eye, leaving an excess length of about 10 cm.
TREADING 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.
TESTING STITCH OVERLOCK STITCHES After threading is completed, use a scrap of Fig. 1 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.
SETTING CHART Note: The above settings of tension and overage cutting with dial are for general guidance. A little fine tuning will improve your stitching in many cases. Following advice helps you: 1. Turn overage cutting width dial (see page 24) 2.
THREE-THREAD OVERLOCK WITH ONE NEEDLE By threading the LEFT needle only a width of 7 mm will be produced and by threading the RIGHT needle only a width of 3.8 mm will be produced. Two-thread overlock convertor Fig. 3 Upper looser Fig.
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.

Stitch length dial ADJUSTING OVEREDGE CUTTING WIDTH Overedge cutting width can be adjusted from 4 to 7 mm by simply turning overedge cutting...
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. Di erential feed dogs POSITIVE DIFFERENTIAL FEED When set for positive differential feed, the front feed dog (A) makes a longer stroke than the rear feed dog (B).
Di erential feed control dial 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 (Posi- tive effect). These settings give the best ratio of feeding. For normal sewing, the dial should be set at 1.
BASIC TECHNIQUES TURNING OUTSIDE CORNERS WITHOUT CUTTING THREADS 1. When you reach the fabric edge, stop stitch- ing 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.
CORDED OVERLOCK Corded overlock can be used to strengthen shoulder, sleeve or side seams when joining or making up knitted garments.

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.
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 Fig. A 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...
DIFFERENTIAL FEED APPLICATIONS Please refer to pages 25 and 26 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.
3. CARING FOR YOUR MACHINE REPLACING MOVING CUTTER Screw Replace a moving cutter if it becomes blunt Moving cutter as follows. A spare cutter will be found in your accessories.
