Case 3 : Normal A and longer B
Adjustment :[P33] Decrease the set value.
B becomes shorter.
Case 4 : Normal A and shorter B
Adjustment : [P33] Increase the set value.
B becomes longer.
Case 2 : Shorter A and normal B
Adjustment : [P32] Increase the set value.
C becomes longer and D becomes shorter.
Case 1 : Longer A and shorter B
Adjustment : [P32] Decrease the set value.
A becomes shorter and B becomes longer.
⑦ Reverse revolution to lift the needle after thread trimming (Function setting No. P46)
This function is used to make the sewing machine rotate in the reverse direction after thread trimming to
lift the needle bar almost to highest position.
Use this function when the needle appears under the presser foot and it is likely to make scratches on the
sewing products of heavy-weight material or the like.

ON Function of making the sewing machine rotate in the reverse direction to lift the
needle after thread trimming is provided.
OFF Function of making the sewing machine rotate in the reverse direction to lift the
needle after thread trimming is not provided.
(Cautions) The needle bar is raised, by rotating the machine in the reverse direction, almost to
the highest dead point. This may result in slip-off of the needle thread. It is therefore
necessary to adjust the length of thread remaining after thread trimming properly.
