Needle precautions
Be sure to observe the following precautions concerning the correct choice of needle for your machine.
CAUTION
Checking the needle
Sewing with a bent needle is extremely dangerous since the needle may break while the machine is
operating.
Place the flat side of the needle on a flat surface and check that the distance between the needle and the flat
surface is even. If the needle is bent or the tip of the needle is broken, replace the needle with a new one.
(Refer to “Changing the Needle” on page 86.)
Bobbin precautions
Be sure to observe the following precautions concerning the bobbin.
CAUTION
Your machine is designed to use household embroidery needles. The factory
recommended needle is “HAX 130 EBBR” (Organ). Schmetz needles 130/705 H-E may be
used as a substitute. Use of any other needles may break the needle or thread or damage
the needle-threading mechanism or result in injuries.
Never use bent needles. Bent needles can easily break, possibly resulting in injuries.
Good needle Bad needle
If the distance between the needle and
the flat surface is not even, the needle is
bent. Do not use a bent needle.

Only use prewound bobbin (COATS “L” type/TRU-SEW
POLYESTER “Filaments”) or bobbins designed specifically for
this machine. Use of any other bobbin may result in injuries or
damage to the machine.
Use a bobbin thread that has been correctly wound, otherwise
the needle may break or the thread tension will be incorrect.
When winding a bobbin, only use optional bobbin winder (refer
to page 240) and metal bobbins (Part code: 100376-053).
When winding the bobbin, be sure to use cotton or spun polyester bobbin thread
(between 74 dtex/2 and 100 dtex/2).
