2.Align a rotor knife with the primary bed knife, in the front of the granulator. With a .006” feeler gauge between the rotor and bed knife, start to adjust the bed knife into the rotor knife using the adjusting screw. During the movement of the bed knife, slowly rotate the rotor back and forth checking the clearance. The proper clearance will be established across the length of the knife when a slight “drag” is felt on the feeler gauge. Partially tighten the bed knife hex head screws. Follow this procedure for all remaining bed knives.

3.If you find a “high” rotor knife, mark it and adjust to this knife.

4.Once knife adjustments are completed, equally and fully torque the bed knife cap screws, working from the center out towards the ends of the knife. Refer to Section 9-11 for the correct torque values based upon bolt size and thread pitch.

5.Re-check the clearance once the bolts have been fully torqued and reset if necessary.

6.Turn the rotor so that the knives are aligned with a secondary bed knife on the rear of the granulator and continue with the same procedure used to setup the primary bed knife.
