HLX5 needles are recommended; however, Schmetz 130/705H needles may also be used under normal
✽
sewing conditions.
Adjust the pressure adjustment dial and the feed dog adjustment knob according to the chart on the sewing
✽
machine.
When sewing on knit fabrics such as jersey or tricot, use a ballpoint needle or a needle designed for use with
✽
knit fabrics.
For best results when using metallic threads, sew with a good quality thread, set upper tension on 2, and
✽
use metallic needle.
Bobbin thread should feed smoothly. Adjust bobbin thread
✽
to match that of upper thread. (If bobbin thread is too tight
it may cause fabric to bunch up.)
