(The machine has a mechanism to
automatically cut off the power to prevent
the motor from overheating.)
● If the thread gets tangled and/or the
needle is bent, motor will lock and safety
mechanism works instantly and the
sewing machine will stop sewing.
● In case of relatively low room temperature
and/or thread tangling, or in case the
motor got excess load, the safety
mechanism works and the sewing
machine stops so that the machine will
not get hot.
● Presser foot is in up position.
● The needle hits presser foot due to an
installation of incorrect presser foot.
● The needle fell into the hook area and
tried to start.
● Thick material is sewn with a thin needle.

tightened.
