Left overedge looper (yellow) With both hands pull the thread through the thread guide (35) and the appropriate thread tension (1, 2, 4, 5). Make sure the thread stays in the slot on the back thread guide (35). Set the thread tension to ,,N” and thread as indi cated.
14 Threading the right overedge looper The slider on the converter (37) must be in the right hand position B (see page 45). Thread the right overedge looper (36) in the order ito 9 and draw the thread to the left under the sewing foot. The thread path is marked in pink.
15 2. Thread the left overedge looper (38) in the order ito 7. Pull the thread from thread guide 7 through the looper eye 8 and pull it a bit with your left hand. 1. The marking on the hand wheel must be in line with the marking on the housing.
16 If the slider on the threader (39) cannot be moved, the marking on the hand wheel is not correctly set. Note: 4. Pull the thread a bit more and at the same time let the slider slowly slide back. The thread is automatically inserted in guide 9. 5. With the tweezers thread the thread through thread guide (10) and draw the thread to the left under the sewing foot.

The threading path for needle B in green (dots). Threading overedge needle A Thread the overedge needle A in the order 1 to 6 and draw the thread through the needle’s eye 7 with the threader. Draw the thread to the left under the sewing foot. The threading path for needle A in blue (dots).
19 Changing a spool when the machine is threaded Cut the threads off close to the thread spool and put on the new spools. Tie the ends of the old thread and the new thread together. Pull the needle threads out of the needles. Lower the sewing feet. Now pull the threads through until the knots are about six inches through the thread guide before the needles. Cut the knots off and thread the appropriate needles.
20 Sewing foot lever The sewing foot is raised and lowered with the sewing foot lever (32). Closing the looper cover When the machine has been threaded you must close the looper cover (13). Note: The power to the machine is cut off if the looper cover is open i.e. it is now impossible to sew. ,,Close looper cover” appears in the display. The LEDs on the speed selection also flash.
S..... Note: Make sure that the threads inter loop correctly when sewing (thread chain). 21 Place a fabric remnant under the sewing foot right in front of the needle and lower the foot. With the threads held slightly taut, slowly begin to sew. Since the fabric is automatically fed, you just need to guide the material with your hands (do not push or pull). Sewing test When the machine has been threaded, you should sew a test seam. First raise the sewing foot.
22 Securing the seam There are various ways of securing the ends of seams: 1. Knot the thread chain. crochet needle. 2. With knitwear you can pull the thread chain into the seam with a and sew round the sewing Turn seam. the of 3. Sew about 2 inches over the end chain. thread the cutting t withou on directi te the opposi in s stitche few back a Thread cutter seam. Draw the To use the thread cutter (25) you must sew over the end of the thread chain that results to the frontover the thread cutter.
a 23 When you have set the seam width you require, press the knob to the right until it catches in place, as indicated by the arrow. This prevents the seam width being inadvertently changed while sewing. Note: The upper knife must be locked when sewing very thick fabrics or fabrics with different thicknesses (see page 30). Note: The seam width settings 3 to 5 are just for needle B. If needle A is used the amount that is set is increased by 2,2 mm to 5,2 to 7,2 mm.
24 Differental feed The differential feed consists of two feed dogs, one behind the other, that assure that the fabric is fed completely evenly. It prevents the displacement of the two fabric lays. The two feed dogs can be set separately i.e. so that the front dog feeds more than the rear dog or vice versa. This is particularly important when sewing rib knit. The differ ential feed is set differently depending on the type of fabric. You can see the settings on page 28.
— 2 = front feed dog longer movement, rear feed dog shorter movement Note: You can also achieve fashionable effects with the differential feed dog: 1. A gathering effect can be achieved when sewing light fabrics with setting 2. 2. A wavelike effect can be achieved for use with rib knit with the setting 0,5. Position 1,5 25 Setting the differential feed You can set the differential feed by turning the adjusting ring (34).
