24. TEST SEWING AND CHAIN OFF

(1) TEST SEWING

* When the machine is completely threaded, bring
all of the threads across the stitch plate and
slightly to the left under the presser foot.
* Ensure that the upper blade moves against the
lower blade correctly by turning the handwheel
slowly toward you. If the blades are not moving
correctly, check if there are any fabric or waste
thread stuck between the blades.
* Hold the threads and apply a slight tension.
* Turn the hand wheel toward you two or three
complete turns to start the thread chain. Check if
all threads wind around the overlocking claw of the
stitch plate. If the threads do not wind around the
claw, make sure each thread is threaded
correctly.
* Lower presser foot.
* Continue holding the chain and press on the foot
controller until the chain is 5~8 cm (2~3 inches)
in length.
* Place fabric under the front of the presser foot and
sew a test sample. Guide the fabric slightly with
your left hand while sewing. Do not pull on the
fabric while sewing as this may deflect the needle,
causing it to break.

(2) CHAIN OFF

* When you reach the end of the fabric, continue
sewing while drawing the finished fabric gently
backwards and to the left. This is called chaining
off. It prevents the threads from coming undone
and prepares for the next sewing task.

* Cut off the thread chain 2-5 cm (1-2") behind the
presser foot using the thread cutter on the left side
of the machine. Pull the threads around the thread
cutter from the back, then toward you.

Note : Anytime you have re-threaded the machine
always chain off and sew a sample to test
tensions and make adjustments as necessary.

Note : The presser foot on this machine has marks
to indicate the needle position. Use this as a
guide when sewing.
