Standard Adjustment
(31) Adjusting the lateral position of the top feed dog
Clearance between top feed dog 4 and presser 3 is 0.2 mm.
a = a’ (0.2 mm)
b = b’ (0.2 mm)
(Caution) 1. Adjust the position only when there is a concrete problem that presser 3 and top
feed dog 4 come in contact with each other and noise occurs, the left and right
clearances are excessively different from each other and trouble occurs, etc.
2. When the adjustment value is improper, there is the possibility that contact among
the components occurs, a bad influence is given to the durability of the sewing
machine or the like since the top feed mechanism is strictly assembled because
of the space. So, be careful.
