■ Changing the minimum trimming margin (Additional DIP switch function)

(Be sure to turn off the power before changing any of the DIP switch settings.  Refer to page 185.)

The minimum trimming margin is set to 2.0 mm (            ) at the time of shipment from the factory to make
allowance for the possibility of striking the needle and the fixed edge knife. The minimum trimming margin can be
changed to 1.5 mm (             ) by the procedure below.
At this time, the maximum zigzag width will also increase by 0.5 mm in the right-side direction.
