1.Locate the height of cut bar and loosen the locknut. Adjust the screw to the desired height of cut by measuring the distance between the top of the HOC bar and the bottom of the screw head as shown. (Fig. 4-11 & Fig. 4-12) Once adjusted, tighten the lock nut.

2.Park the machine on a level surface. Tilt it back to

provide good access to the bedknife, front roller, and drive roller. Secure the machine in position so it will not move.

3.Loosen the height adjustment lock nut on both sides. (Fig. 4-13)

4.Loosen the jam nut on the threaded adjusting rod on both sides. (Fig. 4-13)

5.Raise the front roller by turning the roller height adjusting knobs on both sides in the clockwise direction.

6.On the right hand side, install the HOC bar with the rear of bar pressed up against the drive roller in the rear, then hook the bolt head over the bedknife cutting edge. The HOC bar should be perpendicular to the bedknife. Fig. 4-14 & Fig. 4-15

7.Lower the front roller down, evenly turning both adjusting knobs, to the HOC bar so it comes into contact with the HOC bar, but still allows the HOC bar to be removed.

8.Install the HOC bar on the LH side and adjust the front roller as necessary to come in contact with the HOC bar. Re-check the center, RH and LH sides again to make sure the front roller is properly adjusted and the height is set correctly across the full width of the unit.

9.Tighten the jam nuts on the threaded adjusting rod on both sides.

10.Tighten the height adjustment locknuts on both sides..
