3. Measure the distance between the bottom of the screw
head and the face of the bar to get the height of cut.
4. Hook the screw head on the cutting edge of the
bedknife and rest the rear end of the bar on the rear

Note: For checking the HOC on cutting units installed
with shoulder rollers, place the gauge bar on the
larger-diameter shoulders on the ends of the shoulder
roller.
5. Rotate the adjusting screw until the front roller contacts
the gauge bar

Important: When set properly, the rear and front
rollers contact the gauge bar and the screw is snug
against the bedknife. This ensures that the height
of cut is identical at both ends of the bedknife.
6. Adjust both ends of the roller until the entire roller is
parallel to the bedknife.
7. Tighten the nuts to secure the adjustment.
