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.
