Safety & Operating Instructions

Removing and Replacing the Chipper Knife
Tools Needed:
• 7/16" Wrench
• 1/2" Socket with extension
• 3/16" Allen wrench
• Awl or Sharp Tool
• Gloves
1. Loosen the Locknuts that secure the rear Access Cover with a 7/16"
Wrench (Figure 50). Move the Cover over to align the larger portion of
the hole with the Locknuts and remove the Cover.
2. Rotate the Flywheel using a stick until the three countersunk Allen
Screws (Figure 51) and Locknuts (Figure 52) attaching the Knife to the
Flywheel are visible through the Access Openings.
3. Clean out the heads of the Allen Screws with an Awl or Sharp Tool
(Figure 51).
4. Insert a 3/16” Allen Wrench into the head of a screw.
5. While holding the Allen Wrench, remove the Locknut using a 1/2"
socket
(Figure 52).
6. Repeat Steps 5 and 6 for the remaining two Allen Screws.
7. 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 .
If the flywheel surface is not cleaned properly and the chipper knife is not
mounted flush on the flywheel, the knife could crack when the hardware is
tightened.

8. Install a new or sharpened Knife as shown with the Knife edge facing
down and towards you (Figure 51) and finger tighten the Allen screws
and Lock Nuts (use the new hardware supplied with a new Knife kit) to

9. Using a 3/16" Allen wrench and a 1/2" socket with extension, tighten
the center Screw and Locknut, then tighten the outer Screw and
Locknut, and finally tighten the inner Screw and Locknut.
10. Double-check that all three Locknuts on the Allen Screws are tight.

Plate (See “Checking and Adjusting the Knife to Wear Plate Gap” in
this Chapter).
