1 Upper looper thread
2 Lower looper thread
3 Needle threads
If the machine becomes unthreaded, thread
the lower looper first, then the upper looper,
needle on the right and needle on the left.
* A convenient threading chart is placed the
machine body inside the looper cover.
When first threading the machine, or rethreading
after a break, please do the following:
1 Turn the handwheel toward you until the
needles are in the full up position, and pull
out about 10 cm (4”) of thread from the tip
of the upper looper.
2 Pull out 10 cm (4”) of thread from the tip of
the lower looper.
3 Pull out 10 cm (4”) of needle thread and
draw it toward the back of the machine
under the presser foot.
Now, lower the presser foot and sew.
Incorrect threading will cause skipped
stitches, broken thread or uneven thread
tension.
Before starting to sew, make sure that your
machine is threaded properly.
Turn off the power switch before threading the
machine.
The machine has been threaded at the factory
with short length of thread.
To thread the machine with your own thread,
tie it firmly to the upper end of the thread in the
machine, then raise the presser foot and pull the
other end.
For the needle threads, pull the bottom end of
thread until the knot comes to the needle eye,
and cut on both sides of the knot.
