™ When the loop of the needle thread is not easily formed,
raise the needle thread release as shown in the left figure
at the time of the lowest point of the needle bar.
™ If the needle thread is a cotton thread, raise the right needle
thread release so that the right needle thread only touches
at the time of the lowest point of the needle bar.
™ If the needle thread is a spun thread, lower the needle thread
release so that the needle thread does not touch it.
