3. Rotate the Flywheel using a long stick until the three countersunk Allen

Screws and Locknuts attaching the Knife to the Flywheel are visible through

the Access Openings (Figure 37).

4. Clean out the heads of the Allen Screws with an Awl or Sharp Tool.

5. Insert a 3/16” Allen Wrench into the head of a screw.

6. While holding the Allen Wrench, remove the Locknut using a 1/2" socket.

7. Repeat Steps 5 and 6 for the remaining two Allen Screws.

8. Remove the dull or damaged Knife and visually inspect the Flywheel Slot and

Knife mounting area and be sure they are clean and that the replacement

Knife will be able to mount flush against the Flywheel.

9. Install a new or sharpened Knife as shown (Figure 37) with the Knife edge facing up and towards you and finger tighten the

Allen screws and Locknuts (use the new hardware supplied with a new Knife kit) to hold the Knife to the Flywheel.

10. Using a 3/16” Allen wrench and a 1/2” socket, tighten the center Screw and Locknut, tighten the outer Screw and Locknut,

then tighten the inner Screw and Locknut.

11. Double-check that all three Locknuts on the Allen Screws are tight.

12. Reinstall the two Access Covers.

13. Replace the Belt Guard.

14. Check and if needed adjust the gap between the Knife and Wear Plate (See “

Checking and Adjusting the Knife to Wear

Plate Gap

” in this Chapter).

Removing and Replacing the Wear Plate

Tools Needed:

 7/16" wrench

1. Remove the Hopper (See “

Inspecting the Chipper Knife and Wear Plate”

in this Chapter).

2. Use a 7/16" wrench to remove the three Locknuts and Carriage Bolts that

attach the Wear Plate to the Chipper Assembly and then remove the Wear

Plate (Figure 38).

3. Install the new Wear Plate and secure with the Carriage Bolts and Locknuts.

NOTE: The Gap between the Knife and Wear Plate must be adjusted whenever the

Wear Plate is removed. See the following instructions.

Checking and Adjusting the Knife to Wear Plate Gap

When you replace the Knife or Wear Plate, you must check and set the clearance between the Knife and Wear Plate. Set this

clearance or gap to 1/16" by using the Gap Tool that is supplied with the Chipper and with a new Knife Kit. If the gap between the

Wear Plate and the Knife is not set correctly, you will have excessive vibration when chipping and the Knife will seem to be dull.

The Wear Plate should have a square edge and be free of dents or gouges. The Wear Plate can be hand sharpened (see steps

below). Be careful not to overheat it during the sharpening process. This will change the characteristics of the steel and you will

then have to replace the Wear Plate (see “Wear Plate Sharpening” in this chapter).
