Details of the machine Thread stand A Push the support rod firmly into the socket on the back of the machine. Raise the support rod (A) fully, turning slightly until the position catches engage. Position the thread guide (B) on the thread stand so that the arrow is to the front. B Preparing the machine / Using the machine Attaching the foot control Plug foot control into the machine socket (A) and then into main socket (B). The foot control regulates the sewing speed.
Preparing the machine / Using the machine Waste collector Clip the waste collector into the opening on the looper cover. It catches the cut-off fabric as you sew, keeping your working area neat and tidy. Thread / cones / spools The anti-vibration cone should be used with the wider edge at the bottom on the spool holder pin when sewing with cones. Large spools If large industrial spools are used, position the anti-vibration cone upside down on the spool holder pin, i .e. with the wider edge at the top.
Using the machine Main Power/light switch The main power/light switch is conveniently placed on the handwheel side of the machine in front of the socket. 0 = Off I = On with light Looper cover To open, press to the right with your thumb in the indent provided and tilt the cover towards you. To close push it up and press lightly to the right. The cover engages automatically. Safety device: The sewing machine is equipped with a safety device in order to prevent malfunction.
Using the machine Two step presser foot lifter with integrated front foot lift B To raise the presser foot, lift the presser foot lever on the rear of the machine, until it engages (A). It can be raised again to the maximum height and held in this position to provide more space between presser foot and stitch plate (B). When the foot is raised (A and B), the front of the foot is automatically lifted.
Using the machine How to use the presser foot F G Use the marker on the presser foot as a guide when placing the material under the presser foot. (F) Left needle position (G) Right needle position (H) Knife position (when the lower knife adjusting knob is set at scale mark “1.5”) The knife position represents the position at which the material is cut. H 8.5mm 10mm A B C 11 Inserting the needles Needles can be inserted quickly and easily with the practical needle inserter (A).
Needle and thread Needles B Needles must be in perfect condition. Problems can occur if needles: A are bent. B are damaged or blunt. C have hooked points. C A Needle and thread The needle size used depends on the thread. The needles should be in accordance with thread used. When sewing, the thread is fed through the long groove in the needle. If the needle is too fine, the thread does not fit into the groove and stitches will be skipped. Use needles No. 70 - 90.
Adjustments and settings Stitch length 注意 A It can be adjusted while sewing. The stitch length is infinitely variable from 1-4mm. Most overlock work is done with a basic setting of 2.5mm. For roll hemming or narrow overlocking, it is best to set the dial at “1 to 1.5”. For blind stitch which requires the “use of separately-available A presser foot”, set the dial at “4”. Cutting width Switch the machine off (Power switch to “0”) Disconnect machine from electricity supply. B A • Raise the upper knife.
Adjustments and settings Differential feed 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. It also ensures pucker-free seams in smooth fabric such as nylon or closely woven fabric. Perfectly flat seams in knits or stretch fabrics.
Adjustments and settings Gathering Using the differential feed, a single layer of fabric can be gathered before sewing it to the garment. For example, sleeve heads and lower edges, yokes, lace edging or frills. Adjustment: • Stitch: 4-thread overlock • Differential feed: 2 • Stitch length: 3-4 • Cutting width: 2-3 Increase the needle thread tension (6-8) for a tighter gather. Roll hemming C D M H L 15 • Turn the handwheel towards you until the needles are fully raised.
