●
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: XE3152-221,
green marking), contact your nearest
authorized retailer.
●
Be sure that the bobbin case is correctly
installed, otherwise the needle may break.
