Standard adjustment
6) Adjustment of forward reverse stitches (correction function)
After adjustments described from the above 1) through 5) are completed, check a numerical scale dis-
played on the operation panel and an actual needle-entry. When you set a numerical value to 3 on the
operation panel, put paper under the presser and check a needle-entry pitch with an inching motion (It is
driven at 200 rotations.) . When the needle-entry pitch is more or less than 3 of the numerical scale, make
an adjustment to correct the pitch.
* Even if you have made a pulse motor adjustment, variation in the sewing machines occurs because
of quality of a gauge and so on.
