clockwise with a spanner and decrease
the clearance between the rotary blades
and lower blade.
● The clearance between the rotary blades and
lower blade decreases by rotating the
adjusting nut clockwise and increases by
rotating the adjusting nut counterclockwise.

newspaper torn into a strip at the center,
and right and left sides of the rotary

adjustment, lap (grind) the blade. (See
Adjustment of cutting quality by lapping
