Instructions for using the looper threader
1. If either the upper or lower looper thread breaks while sewing, cut both of the upper and lower threads in front of
the threading holes, and remove the thread from the holes. Rethread both of the threads.
2. When the looper threader switch lever is in the
“THREADING” position, the handwheel is locked. Even if the foot
control is depressed, the handwheel does not rotate.
Do not turn the handwheel. Doing so may cause malfunction.
3. After threading loopers, lower the looper threader lever and return the looper threader switch lever
to “SEWING”
position.
