1. Close the looper cover. Turn the power on.
2. Check that the upper knife is raised.
3. Lower the presser foot.

5. Raise the front side of the presser foot with fingers and
insert the material under the presser foot until the upper
knife is reached.
6. Start the sewing machine.
7. After the completion of sewing, produce chain-off thread
