1. Clearance between top and bottom
feed belts (dimension A) is 0.1 to
1.0 mm. If the clearance is more
than the specified dimension,
components come in contact with
each other.
2. When tightening screw 2, be
careful of the parallel of walking foot
3 and presser foot 4. Bend of
material or feed trouble will be
caused.
1) Bring the needle bar to its upper dead point.

1. Clearance between the bottom surface of presser foot and the needle hole guide has
been factory-adjusted to 0.1 mm at the time of delivery.
2. When the clearance becomes larger than the specified value, feed force is deteriorated.
So, be careful.
