4-5-2. Operating the treadle
1. When the treadle (3) is gently depressed to position (B),
low-speed sewing is carried out.
2. If it is then depressed as far as (C), high-speed sewing is
carried out.
3. When the treadle (3) is pressed forward and then back to
the neutral position (A), the needle will stop below the
needle plate (when needle down stop mode has been
set).
If the needle bar has been set to stop in the needle up
position, the needle will stop at a position above the
needle plate (needle up stop position).
4. When the treadle (3) is depressed all the way to position
(D) (or if the treadle (3) is depressed to position (D) and
then returned to the neutral position (A)), the mechanism
will sew half a stitch or one stitch, and then the needle
bar will stop at the needle up stop position.
(With the 8560A, the thread will be trimmed at this point.)
Furthermore, no needle zigzagging will be carried out at
this time.
