2. Loosen the hex head rotor knife bolts and carefully remove all rotor knives.
3. Clean the rotor knife seats thoroughly with a scraper and/or emery paper to remove any
foreign material or rust.
4. Inspect the knives and replace or resharpen as required.
8.3 Rotor Knife Installation Procedure
1. Carefully block the rotor with a piece of wood to prevent it from turning.
2. Re-install the rotor knives onto the rotor. Do not torque the hex head rotor knife bolts
fully at this point - snug them down only.

New or resharpened knives should be handled with extreme
care. It is suggested that the sharp cutting edges be covered
with tape to prevent damage to the knives or injury to
personnel during installation.
3. Check that the heel of the rotor knife is tight up against the knife seat. Utilizing a .003”
feeler gauge, try to insert it between the heel of the knife and the knife seat at both ends
and across the rotor knife. If the feeler gauge will not go down between the heel of the
knife and the knife seat, the knife is installed correctly.
4. Torque down the rotor bolts. Start from the center of the knife and torque down the bolts
equally, working towards the ends of the knife. Refer to Section 10 for the correct torque
values based on the bolt size and thread pitch. After the bolts on each knife have been
fully torqued, re-check with a .003” feeler gauge between the knife and seat. Use the
same procedure on all remaining rotor knives.
8.4 Bed Knife Installation and Setting Procedure
1. Install the new or resharpened bed knives, shims, and clamps in the reverse of removal.
Make sure the knives are fully back against the knife adjusting screws and loosen the
adjusting screw checknuts slightly. Do not torque the socket cap screws fully at this point
- snug them down only.

personnel during installation.
2. Align the rotor knife with a secondary bed knife on 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 when a slight “drag” is felt on the feeler gauge as it is pulled between the
knives. Once this clearance is established across the length of a knife, partially tighten the
bed knife socket cap screws. Follow this procedure for all remaining bed knives.
