on the bobbin case
is below part

on the sewing
machine.
With the bobbin case tilted to
the left, insert the left side of
the bobbin case into the hook,
as shown.
Left side of
bobbin case
Insert the right side of the bobbin
case into the hook so that part
c
on
the bobbin case is to the left of part
d
on the sewing machine.
Make sure that the bobbin case is fully installed in the hook.
<When correctly installed>
The entire bobbin case fits into the •
hook so that the edge of the hook is
visible.
Part • c on the bobbin case is to the left
of part d on the sewing machine.
<When incorrectly installed>
The right side of the bobbin case •
covers the edge of the hook and
the bobbin case is tilted.
Note:
Carefully check the bobbin case since it may be incorrectly installed
even though part c of the bobbin case is to the left of part d on the
machine, as shown in the above diagram on the right.
Edge of hook
Make sure that
the bobbin case
moves slightly in
the direction of
