TESTING STITCH OVERLOCK
STITCHES
After threading is completed, use a
scrap of fabric that you plan to sew and
test to sew in the following order.
1. Gently pulling all the threads to the
left, lower the presser foot. Rotate
the hand wheel towards you a few
times to see if the lock stitches are
properly formed.
2. Start the machine at low speed and
feed in test fabric under the presser
foot by slightly pushing it forward.
(This can be done with the presser
foot down on most fabrics except
bulky materials.)
Guide the fabric gently as machine
automatically feeds the material.
3. Check thread tensions by test sewing
on spare fabric. (See page 17.)
4. At fabric end, carry on running
machine at low speed, gently pulling
the fabric towards the back, until
about 5 to 6 cm of extra lock stitches
are produced without fabric.
5. Cut thread by thread cutter in face
cover, or with scissors.
