(1) Height of the feed dog
1) To adjust the height of the feed dog, loosen
setscrew ❶ , shown in the figure, and turn feed
driving link shaft ❷ with a screwdriver.
2) The standard height of the feed dog is 1.2 mm.
3) To adjust the inclination of the feed dog relative
to the throat plate, loosen two setscrews ❸ ,
shown in the figure, and turn the feed bar shaft
with a screwdriver through the hole in the bed.
4) For the machine with a thread trimmer, there can
be no space between the counter knife and the
underside of the feed dog when adjusting the
feed mechanism (change in height and timing)
or using a commercially-available feed dog.
In this case, place a feed bar spacer (part num-
ber : 10025906) under the feed mechanism and
a throat plate spacer (part number : 22503908)
under the throat plate so as to secure a space
between the counter knife and the underside of
the feed dog.
(2) Inclination of the feed dog
The standard inclination of the feed dog is
obtained by adjusting so that the feed dog be-
comes level when the feed dog goes up above
the top surface of the throat plate.
When you replace the sewing hook, remove it in the
following procedures;
1) Turn the handwheel until the needle reaches to
its highest position.
2) Remove the needle, presser foot, throat plate,
feed dog and bobbin case from the machine.
3) Remove the setscrew ❶ and take out the bobbin
case positioning finger ❷ .
4) Loosen the two screws ❸ and remove the sew-
ing hook ❹ .
* Reverse the above procedures when inserting
the sewing hook.
At this time, make sure that top end A of the
bobbin case positioning finger is aligned with line
B as shown in the figure on the left. Never let A
protrude from line B.
