What this passage proves
- knife fact — knife system: integrated adjustable knife/cutting-width system
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)
