Draw the thread to the left under the sewing foot. The threading 1 1 path for needle B is marked in blue (dots) for needle C in green (dots).
Closing the looper cover When the machine has been threaded you must close the looper cover (14). 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.
Sewing test When the machine has been threaded, you should sew a test seam. First raise the sewing foot. 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.
Thread cutter To use the thread cutter (26) you must sew over the end of the seam. Draw the thread chain that results to the front over the thread cutter. oO / Securing the seam There are various ways of securing the ends of seams: 1. Knot the thread chain.
Setting the seam width a The seam width adjusting knob (17) is released if it is pressed the right. You can now set the seam width you require as indicated in the window (19). The range is from 3 to 5 mm and is infi nitely variable. The standard setting N is 3.

as Setting the differential feed You can set the differential feed by turning the adjusting ring (35). The range from 0,5 to 2 is infinitely variable and is indicated in the window (9).
This table shows possible settings for the differential feed. Sew a test seam to deter mine the correct setting for your fabric. The differential feed can also be set while sewing.
Changing the needle Switch off the main switch. To remove: Lower the sewing foot and put the needle in its highest position. Now push the needle changing aid from the accessories (see page 66) from below right up until it catches over the needle. Loosen set screws (A, B or C) with the red screwdriver and pull the needle down to remove.

‘I Setting the standard thread tension Uniform thread tension depends on the type of fabric and the thickness of the thread. The thread tension should be corrected after the thread interloop has been- checked (see page 43 to 47). Turn the values indicated on the thread tension thumbwheels to the corresponding colour symbol.

Prog. 4 or 5 3 thread overlock seam (narrow or wide) The 3 thread overlock seam is sewn with two looper threads and one needle thread (needle change page 29). The set seam widths 3 to 5 mm in the window (19) only apply to needle C. If needle B is used, the setting is increased by 2,2 mm (seam width 5,2 to 7,2 mm).
Converter A serging seam is generally sewn with 3 threads. If you connect the converter you can dispense with one thread i.e. you just continue to sew with 2 threads and thus save a lot of thread. Wherever a 2 thread seam is enough i.e. for elastic materials and materials that hardly fray, you can still make neat edges with less thread.
The left hand thread that runs over the right looper must be pulled over the poin of the right looper in the direction of the arrow as in this illustration.
