Standard Adjustment
(32) Position of the motion of the top feed dog
1. The position of motion is adjusted to rear constant for 50H and 60H series and MO-6900J, and to
intermediate constant for other models at the time of delivery so that the best locus suitable to the
purpose of use can be obtained.
2. Intermediate constant position at the time of delivery
The position of motion of the top feed dog other than that of 50H, 60H and MO-6900J is adjusted
to the position where the top feed dog does not move even when the top feed lever is moved at the
position where the timing is advanced by 19˚ from the upper dead point of needle.
(33) Adjusting the feed bar guides A and B
When the play of the top feed dog in the lateral direction is excessively increased, the play can be
removed by adjusting the feed bar guides A and B.
