Case
● The machine stops sew-
ing suddenly.
(This is in case you
can turn hand wheel by
hand.)
● Sewing machine stops

wheel is heavy to turn.)
● Sewing machine stops
after sewing some stitch-
es.

work even when started.

50
Cause (Reason)
● The machine sews at slow speed con-
tinuously.
(The machine has a mechanism to auto-
matically 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 sew-
ing machine will stop sewing.
● In case of relatively low room tempera-
ture and/or thread tangling, or in case
the motor got excess load, the safety
mechanism works and the sewing ma-
chine 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 nee-
dle.
● The needle is not inserted fully.
● The needle setscrew is not securely
tightened.
● The wrong presser foot is used for a
certain pattern.
● Lint or dust has accumulated in the feed
dog.
● Lint or dust has accumulated in the
hook.
● The stitch length is set at "0".
● Soft fabrics such as towels are being
sewn.
● The machine is set in drop feed condi-
tion. (the drop feed knob is on the right
side)
Solution

while (about 10 minutes). The safe-
ty mechanism will be reset and the
machine will return to normal.
● Get rid of cause(s) of thread tangling.
● Check if the needle is bent or not.
* Turn off the power before checking
the needle.
● Leave the sewing machine in the
room so that the sewing machine
adapts itself to the room tempera-
ture.

sew.

the selected stitch pattern.
● Remove the needle from the hook
area.

thread and needle.

● Securely tighten the needle set-
screw.

tern and presser foot to be used.
● Clean the feed dog area.
