12) 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 44 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 firmly.
13) 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.
⑴ Adjusting the strokes of both to be the same
The maximum height of the auxiliary presser foot ① and the upper feed② presser foot is up to 5.5 mm.
Loosen the nut ③.
Move the nut ③ up or down, depending on sewing materials. Move it up to make the stroke increased or down to
make it decreased.
After adjustment, check the timing adjustment explained in ④, page 24.
