Remove the two 3/8" bolts on the rotor access cover.

1.

lift rotor access cover and expose rotor.

2.

Measure the amount of clearance between chipping

3.

blade and chipping anvil from inside the housing.
loosen the three 1/2 inch bolts that hold the chipper

4.

anvil to the frame. The bolts are accessed underneath

the feed roller (see picture below).

Adjust anvil inward or outward to the correct clearance.

5.

check how all blades clear the anvil.
Tighten bolts on chipping anvil to 75 ft. lbs. and bolt

6.

rotor access cover closed.

If the chipping anvil edge is damaged or worn unevenly,

remove the three bolts holding the anvil and use one of the

other three edges. Adjust for correct measurement.

The chipping blades should clear the anvil by 1/16 inch to

1/8 inch. check the clearance every 8 hours of operation

and adjust if needed. The chipping anvil is reversible. All

four sides of the anvil can be used for chipping.
To adjust the anvil:

The blades can be ground on a bench grinder or by a

professional.
1. Never sharpen or grind the mounting surfaces of the

blades. This will cause the edge to roll and the blade will

be damaged, resulting in poor chipping performance.

2. Regrind the angled edge of the chipping blades to 45

degrees (see below). Make sure some type of fixture is

used to correctly hold the blade at the proper angle.

3. Be careful when grinding so that the blade does not

become overheated and change color. This will remove

the heat-treated properties.

4. use short grinding times and cool with water or some

type of liquid coolant.

5. Remove an equal amount off each blade to maintain

rotor balance.

6. Small imperfections such as nicks and burrs on

the flat side of the blade will not affect the chipping

performance of the machine.

7. For blades that have been repeatedly sharpened,

ensure that the sharpened surface extends past the

chipping slot opening. If it does not extend past the

opening, the blades should be replaced.
