10) Adjusting feed dog height
Turn the pulley so that the feed dog ① is positioned at its hight to adjust the feed dog ①. Loosen the fork clamp screw ④ of
the feed dog base as in Figure 29 and move the feed dog base up and down so that the feed dog protrudes about 1 mm from
the needle plate top. After adjustment, fasten the clamp screw ④ firmly.
11) Adjusting the auxiliary presser foot and the upper feed presser foot
※ Both the auxiliary presser foot and the upper feed presser foot move up and down.
※ It is normal that both of them move up and down to the same height.
※ Take the following steps either to adjust the stroke of both to be the same or to make one of the two adjusted lower or
higher, depending on sewing materials.
(1) Adjusting the strokes of both to be the same
A) The vertical motion range of the supplementary presser foot① and the upper feed presser foot② is 2~6mm.
B) Loosen the adjusting hinge screw ③.
C) Vertically adjust the hinge screw③ depending on sewing fabric. When the motion range is set large, move the
adjusting hinge screw③ upward. Otherwise, move the adjusting hinge screw downward.
