2. First bar adjustments
Turn the handwheel until the control spring engages into a
detent. Check the distance 1-2 mm between the control spring
and the shifter arm. If the distance is different, move the shifter
arm after which is locked by two M4 screws ➎.
Check the quality of the sewn buttonhole on the paper. If the
stitches are uneven ➏ follow below described adjustment:
Loosen the nut ➐ and turn the nut ➑ clockwise. This adjustment
will provide the even stitches ➒ in the first bar.
If the length of the buttonholes ➓ is not the same, adjust the
brake.

density in the bar may be increased.
