Inserting the bobbin
Insert the full bobbin in the bobbin case. When doing so, pull
the thread sideways through the slot on the bobbin case (A),
then under the tension spring (B) until it rests in the small hook
in the opening (see arrow).
Check: When you pull the thread, the bobbin must turn clock-
wise.
Inserting the bobbin case
Lift the latch (F) on the bobbin case and push the bobbin case
fully onto the pin (D) of the sewing hook. The opening (E) of the
bobbin case must face upwards.
Check: Pull the bobbin thread sharply. The bobbin case must
not fall out of the hook.
Close the hook/bobbin cover.
