*Height of the lower knife
Loosen setscrew 2 and adjust the height of lower knife 1 so that its edge is flush with the throat plate
surface.

*Height of the upper knife
Loosen setscrews 4, and perform adjustment so that upper knife 3 overlaps lower knife 1 0.5 to 1 mm when the upper knife is at its lower point.

*Overedge width
Overedge widths of 1 .6 through 6.4 mm (some of subclass models : 4.8 through 10 mm) are provided by changing the parts or by using subclass models. (The overedge width will be slightly larger than the knife cut width.)

To change the overedge width:
1) Loosening setscrew 5 push lower knife 1 to the left and fix it.

2) Loosen setscrew 6 and move upper knife 3 as required, then fix it.

3) Lower the upper knife to its lowest point and loosen setscrew 5. Tighten setscrew 5 when the lower knife comes in contact with the upper knife.
 

Be sure to tighten screw 5 before operating machine.
After the completion of adjustment, make the knives cut a thread to check for sharpness of the knives.
