How to use the looper threader
To thread woolly thread or any thread that cannot
pass smoothly through the threading holes, it is
recommended either to use the “looper threader”
supplied in the accessory bag, or to prepare an ap-
proximately 30 cm long spun thread or the like, tie it
at the end of the woolly thread, pass the spun thread
through the threading hole and pull it until the woolly
thread passes through the hole.
(The looper threader can also be used as a cleaning
tool for pipes.)
1. Raise the threading changeover lever in the di-
rection of the arrow.
Turn the handwheel toward you until it clicks.
2. Pass the thread through the looper threader ring.
3. Pass the looper threader through the looper by
hand until it comes out from the end of the looper.
Caution:
Do not press the air-control pushbutton.
Note:
If the upper or lower looper thread breaks during
sewing, re-threading is necessary. Remove both
the broken and unbroken looper threads. Then, set
the threading lever to the threading side to carry out
threading of the upper and lower loopers.
Caution:
After the completion of threading of the upper and
lower loopers, return the threading lever to its home
position. If not, the looper cover cannot be closed.
