2-3 Test sewing
Ensure that the upper blade moves against
the lower blade correctly by turning the
handwheel slowly towards you. If it is not set
correctly, check if there is any fabric or waste
thread stuck between the blades.
Turn the handwheel towards you while
holding all 4 threads and applying slight
tension.
3. Sewing
3-1 4-thread overlock stitch using
2 needles
Before sewing
When threading is complete, sew a few inches
of chain stitches.
Presser foot lift
Position the fabric by lowering the presser
foot lift to raise the presser foot.
Place the fabric underneath the presser foot
and push the fabric towards the front of the
blade.
Lower the presser foot.
Note: For thin and middleweight fabrics,
there is no need to raise the presser foot.
Check all 4 threads wind around the stitch
finger of the needle plate. If all 4 threads
do not wind around the stitch finger of the
needle plate, check and make sure that
each thread is threaded correctly.
