• Never use a bobbin case that is scratched;
otherwise, the upper thread may become tangled,
the needle may break, or sewing performance may
suffer. For a new bobbin case (part code: XC3153-

embroidering with bobbin thread recommended by
Baby lock) or XC8167-251 (pink marking on the
screw) (for embroidering with bobbin threads from
other manufacturers)), contact your authorized
retailer (see page 141).
• Be sure that the bobbin case is correctly installed.
Otherwise, the needle may break.

When cleaning the bobbin case, use business card
stock or another type of paper of similar thickness and
sturdiness in order to prevent pieces of paper tearing off
