Setting the Cutting Width
The cutting width for the knife position can be adjusted between 5 – 7mm. The numbers on the scale
correspond with the actual cutting width in mm from the left overlock needle «LN» to the cutting edge. The
cutting width is used to determine the stitch width. Towards the right overlock needle, the cutting width is
reduced by 2mm. The cutting width has a direct effect on the stitch width. (see page55)
If the cutting width changes, the knife, the stitch finger and the threader cover move in the corresponding
direction.
> To increase the cutting width, turn the cutting width dial to a higher value.
> To reduce the cutting width, turn the cutting width dial to a lower value.
