Loosen the screws ②, ④, and ⑥ to adjust the differential
feed dog ①, the main feed dog ③, and the auxiliary feed
dog ⑤ respectively.
To set the standard position, set the tops of the main ①
and differential feed dogs ③ parallel to that of the stitch
plate when the tops of the feed dogs are raised and even
with that of the stitch plate.
Make the height between the top of the stitch plate and
the rear side of the main feed dog ③ to 0.8 mm when the
feed dog is at the highest point.
Install the auxiliary feed dog ⑤ 0.5 mm lower than the
main feed dog ③ as standard.
1. Be sure to make no difference of installing height
between the main feed dog ③ and the differential feed
dog ①. If different, it can cause the unstable feeding
and feed scratch mark.
2. For sewing heavy weight knitted fabric or the mate-
rial having uneven thickness parts, adjust differential
feed dog ① and main feed dog ③ 1.0 ㎜ higher than
standard position respectively.
