Figure 7. Anvil Clearance
The chipper blades should clear the chipping anvil by 1/16 inch. Anvil is located directly under the chipper discharge opening. Follow steps to adjust the blade clearance:
1.Remove the discharge cap or optional discharge tube for easier access to the anvil.
2.Rotate the disk assembly until a chipper blade is even with the chipping anvil.
3.Measure the amount of clearance between the chipper blade and the chipping anvil from inside the chipper housing. The minimum distance between the blade and the anvil should be 1/16 inch.
4.Adjust the chipping anvil by loosening the 5/16 bolts holding the anvil to the disk cover and sliding the anvil inward or outward until the 1/16 inch clearance is achieved.
NOTE: If the chipping anvil is damaged or worn unevenly, remove hardware holding anvil to the disk cover. Rotate anvil to use one of the other three edges.
5.Tighten hardware to 19 lbs-ft.
6.Install discharge cap or optional discharge tube.
