INSERTING THE BOBBIN CASE INTO
THE ROTARY HOOK
Note: When inserting the bobbin case into the rotary hook, make
sure the thread tail is no longer than 3 inches (7 cm). A longer tail
can wrap around the shaft and create a buildup of thread. If the
thread is not long enough, the needle will be unable to grab it.
• Hold the bobbin case by the bobbin case release latch
with the pigtail facing up.
• Insert the bobbin case into the rotary hook by aligning
bobbin case with the rotary hook groove (1).
• Push in the bobbin case slightly and make sure the
bobbin case clicks into place.
• Close the bobbin housing unit.
REMOVING THE BOBBIN
1. Open the bobbin housing unit.
2. Identify the thread hook. If thread hook is not
forward, then pull it forward.
Note: Do not pull thread hook beyond its capacity. It only moves to a
certain extent.
3. Grab the bobbin case by the bobbin case release latch.
4. Gently remove the bobbin case from the machine.
5. Remove the empty or nearly empty bobbin from the
bobbin case and discard or rewind.
