Adjusting Feed Timing of the Needle Bar, Presser Foot & Feed Dog
1. Raise the presser feet and set the stitch
length to 8mm. Turn the balance wheel
to lower the needle into the hole of the
feed dog and check to see if the needle
is centered in the hole at the feed dog’s
forward most position (A).

NOTE: If the needle if not centered in the feed
dog hole (A), see page 31.
2. Keep turning the balance wheel until a full
rotation is achieved. If the needle is still
centered in the feed dog hole (A) throughout
the movement, then the mechanism is
timed properly. If it ends up in position (B),
this indicates that the feed amount of the
needle bar and presser foot is larger than
that of the feed dog. To correct this, you will
need to reduce distance (C). Use a wrench
and loosen the nut. Slide the nut and its
connected pivot block up. If the timing is
off and the needle ends up at position (D),
then the feed amount of the needle bar and
presser foot is smaller than that of the feed
dog. In this case, enlarge distance (C) as
explained above, but slide the nut down.
Make adjustments until the needle arrives
at (A) (the center of the feed dog hole at the
end of the rotation).
