— — Spool holder Before placing thread cones/spools on machine you must pull the spool holder 41 fully away from the back of machine. Thread net & Synthetic threads generally unwind too quickly from the thread spool. Thread nets have been included to allow easy use of the se threads.
It is advantageous to use the thread unree ling disc 44 when sewing with large spools (5,000 — 10,000 m). To do this, place the cone thread adapter 43 onto the spool pin 42. With synthetic threads, the spool discs take up any play or surplus in the thread and guarantee excellent thread feed.
Presser foot • ‘4 ‘ With the standard presser foot 10 use the setting “A” of the spring-loaded presser foot latch for the cover stitch programs (Progs. 1, 2, 3), the two-thread chainstitch (Prog. 4), the 4-thread safety-stitch seam (Prog. 191 and the 5-thread safety-stitch seam (Prog.

Differential feed The differential feed consists of two feed dogs (A + B), one behind the other, which feed the fabric. The movement of the front feed dog (A) and thus the amount of material to be fed can be regulated using the regulator wheel 49. The setting range is between 0.
Set the regulator wheel for the differential feed 49 to 2.0. Here the front feed dog feeds twice as fast as the rear feed dog. This means that the front feed dog feeds twice as much fabric as the rear feed dog, causing the material to gather. Here you will avoid stretching in the seam when working with knitwear, such as jerseys or gathered fabrics.
