16. Sett ing the cutt ing width
Depending on the material, it may be necessary to vary the cutting width.
Check each time which stitch width is suitable using a sample stitch. You
can freely adjust the cutting width from 3 to 4.5 mm. To do so, proceed as
follows:
1. Fold the looper cover (13) down.
2. Bring the needles to the highest position by turning the handwheel
(38).
3. Position the upper knife (14) upwards, as described in section "18. Dis-
engaging the upper knife" on page 245, this makes it easier to set
the cutting width.
4. Turn the cutting width setting control (45) to the desired setting.
5. The cutting width set is shown on the front edge of the throat plate.
When the desired stitch width is set, the edge of the knife fitting and
the respective cutting width marking on the throat plate line up.
6. Position the upper knife back in its original position and close the
looper cover.
