Check the condition of the needle, and then
install it.
If the needle is in a poor condition, for
example, if it is bent, be sure to install a new
needle.
• Refer to “Checking the needle” (page 30)
and “Replacing the needle” (page 30).
Note
● After completing this procedure, continue
with the following procedure in “Checking
machine operations” to check that the
machine is operating correctly.
Memo
● Since the needle may have been damaged
when the fabric was caught in the machine,
we recommend replacing it with a new one.
● 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: XE7560-001), contact your
nearest authorized service center.
● Make sure that you fit the bobbin case
properly, otherwise the needle may break.
CAUTION
● Never use bent needles. Bent needles can
easily break, possibly resulting in injuries.
