When inserting the needle, make sure that the groove
of the needle is facing front. Shaft of the needle should
be inserted completely into the needle bar.
[CAUTION 1]
For special threads such as artificial silk, turn the
needle slightly to the right to prevent thread breaks
(see [Fig.5-25]).
[CAUTION 2]
If the needle is not inserted all the way to the top of
the needle bar hole, timing of the machine will go off,
causing broken needles and thread breaks.
