3 To thread the machine
Thread the machine correctly by referring to pages 3 to 9.
Incorrect threading may cause skip stitching, thread breakage and/or uneven stitch
formation. When threading the looper, tilt the looper holder toward the front of the
machine using the looper drawing bar.
■
To tilt the looper toward the front
1. Bring needle bar A to the top of its stroke.
2. Pay out the needle thread from the spool by pressing a finger down on needle threads
B.
3. Pull looper drawing bar knob C out to the left so that the looper holder is tilted
toward the front of the machine.
4. After the machine is threaded, replace the looper by pressing looper holder D into the
machine until it clicks.
< Note >
The looper pops out of the machine as soon as knob C is pulled, so do not bring your fingers
close to the looper.
