LOOPER THREADING
Warning: Before contriving please adjust main control switch to (OFF).
Correct threading is important otherwise uneven stitches or thread breakage may result.
Aconvenient threading chart is placed on the front panel inside the front cover.
In addition, each thread guide is coloured for
threading indication.
To help in threading, tweezers can be found in
the accessory box.
Threading must be carried out in the following
sequence.
1. FIRST……...Upper looper
2. SECOND…..Lower looper
3. THIRD……...Right needle
4. FINALLY……Left needle
1. Open thefront cover and free arm.
2. Turn the handwheel toward you until. the
looper comes to best position for threading.
3. Pass the upper looper thread and lower
looper thread as illustrated.
Important: The thread must lie correctly
between the two discs inside the tension
dials.
4. Pull out the thread end about 10 cm (4")
long from the looper eyes. Raise the
presser foot and place threads under it,
then lower the presser foot.

breakage during sewing, start sewing in the
following manner.
Holding the end of threads between your left
finger tips, turn the handwheel slowly toward
you two or three times and check the thread
chain.

foot and start sewing slowly.
The fabric will be automatically fed.
Guide the fabric as you sew.
When work is finished, continue sewing to
form about 5 cm (2") long thread chain from
the end of fabric.
Cut the threads with a scissor.

CHANGING THE THREAD (TYING ON)
It is simple to change the thread in the following
manner.
Cut the thread above the spool pin, and knot
ends of old and new threads together.
Set the tension dials to "O" and raise the
presserfoot.
Pull the other end of thread until knots come
under the presser foot. For needle threads, pull
theother ends of threads until knots come to
needle eyes and cut the threads at the both
sides ofthe knots. Then re-thread the needles.

The proper cutting width differs with the type offabric. Check the seams each time, and adjust the
cutting width as follows.
1. Turn the hand wheel toward you until the needles are at the lowest position.
2. Open thefront cover and free arm.
3. Turn the cutting width adjustment knob until the looper threads lies along the edge ofthe fabric.
Adjust to a narrower cutting width if the fabric edges curl when sewing. Turn the cutting width
adjustment knob to the right.
Adjust to a wider cutting width ifthe thread loops off the edge of the fabric. Turn the cutting width
adjustment knob to the left.
