Silvercrest SON 90 A1 - Manual (Page 130)

Binding-off and sample sewing
• Lay all yarns under the sewing foot a, to the rear, slightly to the left
and over the stitch plate e.
• Firmly hold the yarns under a slight tension.
• Turn the handwheel 6 2 to 3 revolutions onto itself to begin empty
chainstitch formation.
• Lower the sewing foot a with the sewing foot lever 4.
• Hold the empty chainstitch again firmly and carefully activate the foot
pedal until the empty chainstatch is approximately 5 - 7.5 cm long.
• Place the fabric from the front under the sewing foot a and sew a test
seam (Fig. 51). Under no circumstances should you pull on the textile,
otherwise the needle will be bent or could even break off.
• Continue sewing even after the textile is finished for about 15 to 20 cm.
• Cut the empty chainstitch by using the blade at the rear of the machine
(Fig. 52).
Recommended tension settings
Note:
All information about tension settings for the different kinds of stitches are
purely guiding values. The thread tension itself is always dependant
on the type and thickness of the fabric, as well as needle strength and
the strength, type and material composition of the yarn.
It is therefore absolutely necessary to sew a test seam. It is the only way
you can find out if the tension settings are correct, or if they need to be
changed.
