6-2-4-6. Adjusting the knife pressure
Under the manual mode, press the axis 2 button.
Turn the knife to change its direction so as to allow
easy adjustment.
Push a hexagonal wrench key into the slot in the set-
screw (in the direction of the left arrow) and loosen
the setscrew until the counter knife is aligned with
the moving knife while lifting the setscrew in the
direction of the up arrow to allow the counter knife to
be pressed against the mounting base.
After you have loosened the setscrew, push the ad-
justment screw keeping the setscrew held loosened.
Target knife pressure is 0 (zero). (So that
the moving knife comes in slight contact
with the counter knife)
After you have pushed the adjustment screw, tighten
the setscrew.
Adjust the counter knife and the moving knife until
they are aligned well with each other.
