Safety & Operating Instructions
4.
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 31 and 32).
5.
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.
7.
While holding the Allen Wrench, remove the Lock Nut using a 1/2"
socket. Be careful not to drop the Lock Nut into the Chipper.
8.
Repeat Steps 6 and 7 for the remaining two Allen Screws.
9.
Remove the dull or damaged Knife and clean any debris out of the
Flywheel
Slot and Knife mounting so 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.
