Raise the needle by turning
the balance wheel toward you
and lower the presser foot.
Switch off the machine and disconnect the machine from the power point.
Loosen the needle clamp screw by turning it counter-clockwise.
Undo the needle clamp screw just enough to release the needle.
Remove the needle from the clamp.
Insert the new needle into the needle clamp with the
flat side away from you.
When inserting the needle into the clam, push it up as far as it will go and
tighten the clamp screw firmly with the screwdriver. Please do not over tighten as
this can snap the needle bar. Thread the needle.
Reconnect the machine to the power point, switch on the machine and continue
to sew.
Check your needles frequently for barbed or blunted points. Snags and
runs in knits, fine silks and silk-like fabrics are permanent and are
almost always caused by a damaged needle.

Thread and Needle Chart
•
In general, fine threads and needles are used for
sewing thin fabrics, and thicker threads and needles
are used for sewing heavy fabrics. Always test thread
and needle size on a small piece of fabric which will
be used for actual sewing.
• Use the same thread for needle and bobbin.
•
When sewing stretch, very fine fabrics and synthetics,
use a BALL POINT needle. The blue tipped needle
effectively prevents skipped stitches.
• When sewing very fine fabrics, sew over a
piece of
paper to prevent fabrics distortion.
