1) To adjust the height of the feed dog, loosen the
screw 1 and turn the feed driving link pin 2 using
a screwdriver.
2) The standard height of the feed dog is 1.2 mm.
3) To adjust the inclination of the feed dog, loosen the
two screws 3 and turn the eccentric shaft inserting
a screwdriver through the adjustment hole in the
machine 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 No. : 10025906) under
the feed mechanism and a throat plate spacer (part
No. : 22503908) under the throat plate so as to
secure a space between the counter knife and the
underside of the feed dog.
The standard inclination of the feed dog is obtained
by adjusting the feed dog so that it becomes horizontal
when it rises above the top surface of the throat plate.
