Needles Breaking.

See that the needle is not bent, the upper
tension is not too tight, and the presser foot
or attachments are securely fastened. Avoid
pulling the material and do not sew heavy
seams or thick goods with too fine a needle
(see table on inside of back cover).

Thread Breaking.

If the needle thread breaks, see that:
The machine is properly threaded.
The upper tension is not too tight.
The needle is not bent, blunt or set
incorrectly.
The thread is not too coarse for the needle
(see table on inside of back cover).
The thread take-up spring (4, Fig. 5) is not
broken.
Should the under thread break, loosen the
under tension (see page 11), and see that the
shuttle and under the tension spring are free
from fluff.
