[. . . ] Read all safety regulations carefully and understand them before using your sewing machine. Retain this instruction manual for future reference. When using an electrical appliance, basic safety precautions should always be followed, including the following: Read all instructions before using this overlock sewing machine. The appliance should never be left unattended when plugged in. [. . . ] Sewing and special overlock threads are manufactured in a wide variety of types, weights and combination of fibres. It is worth investing in good quality threads for perfect sewing results. Decorative threads specially made for overlockers (available on cones) are also becoming widely available. We recommend following the basic guidelines when using special threads on your overlocker: - Purchase threads on cones or spools which are produced exclusively for overlocking. - When using normal spools, use the spool caps (in accessory bag). - Only use decorative threads in the loopers. The thread must move easily and without resistance through the thread guides and looper eyes. Pull the thread chain gently to the rear when starting to sew. Always test sew decorative threads before starting to sew your work. All purpose overlock 70-90 looper threads thread120/2(polyester) Polyester-continuous filaments Woolly nylon Spun Polyester 80-90 Loopers only Loopers only Neatening edges Soft seams in knits, rolled hems. the stitch length is infinitely variable from 1-4mm. Most overlock work is done with a basic setting of 2. Switch the machine off (Power switch to "0") Disconnect machine from electricity supply. Increase the cutting width if the loops seem to be too loose (B). There are two feed dogs one front (C) and one rear (D). The two feed dogs move independently and the distance each feed dog travels during one complete movement can be adjusted. The differential feed prevents fluting or waving in knitted or stretch fabrics and movements between the layers of fabric. The distance travelled by the front feed dog should be greater than that of the rear feed dog. The front feed dog, therefore, feeds an amount of fabric which the rear feed dog can take up behind the needle without stretching the fabric. (E) Pucker - free seams in nylon or closely woven fabrics. The distance travelled by the rear feed dog should be greater than that of the front feed dog. The front feed dog, therefore, holds the fabric back so that the rear feed dog can take it up behind the needle without any puckering. [. . . ] Raise the tip of the foot and turn work away from you. Leave a 12 cm / 5" chain at the beginning and end of the seam so that it can be knotted or pulled through the first/last few stitches with a darning needle. The upper knife (moving knife) is made from special hardened material. Replace the upper knife only when the knife blade tip is damaged. [. . . ]
