Rotate the Flywheel using a long stick until the three countersunk Allen
Screws and Lock Nuts attaching the Knife to the Flywheel are visible
through the Access Cover and Hopper openings (Figure 33 and 34).

Clean out the heads of the Allen Screws with an Awl or Sharp Tool.
6.
Insert a 3/16” Allen Wrench into the head of a screw.

Be careful not to drop the Lock Nut into the Chipper.
8.
Repeat Steps 6 and 7 for the remaining two Allen Screws.

Slot and Knife mounting so the replacement Knife will be able to mount
flush against the Flywheel.

Double-check that all three Locknuts on the Allen Screws are tight.
13.
Reinstall the Access Cover and Hopper Assembly.
14.
Replace the Belt Guard.
