Threading and Sewing
2
Maximum Material passage for your project is 6
mm.
After threading is completed, use a spare piece of the same fabric
to be used to sew and do a test sewing.
⦁
Preset the basic thread tension, position of the Rolled Hem
Selection lever, the Cutting Width, Stitch Length, Differential
Feed and the Upper Looper Converter as required. „Stitch
overview" see page 23
⦁
Pull all the threads behind the Presser Foot, to the left.
⦁ Lower the presser foot.
⦁ Turn the handwheel several times counter-clockwise to see if a
chain is formed.
⦁ Position the test fabric under the front of the presser foot (with
most fabric this can be done when the presser foot is lowered)
and sew slowly.
⦁ Guide the fabric gently as the machine feeds the material auto-
matically.
⦁
Check the stitch formation and optimize if necessary. Depend-
ing on the result adjust following settings:
̶ „Adjusting thread tensions" see page 32
̶ „mtc Thread control (Micro Thread Control)" see page 21
̶ „Presser foot pressure" see page 21
̶ „Differential Feed adjustment" see page 22
̶ „Cutting width" see page 20
̶ „Stitch length" see page 20
⦁ At the fabric end, carry on running machine at low speed, gen-
tly pulling the fabric towards the back, until an extra chain of
stitches is produced without fabric.
⦁ Pull the threads from the back over the thread cutter (1) or cut
with scissors (2).
