Shredding Hammer Rotation and Replacement
The cutting edges of the shredding hammers may eventually wear out requiring rotation of the
hammer or replacement if all cutting edges have been dulled.
To rotate the shredding hammers:
1. Turn the engine off and wait for all moving parts to stop.
2. Disconnect the spark plug wire and secure it away from the spark plug.
3. Detach the rotor housing and hopper from the rotor plate. See Figure 9.
4. Note the assembly sequence of the hardware used to secure the hammers. Using an allen wrench,
remove the socket head cap screw (A) and related hardware. See Figure 10.
5. Inspect the hammers (D), spacer tubes (C, E), and hardware. If the spacer tube (E) shows signs of
wear, replace it. Inspect and flip, or replace the hammers (D).
6. Reassemble the hammers, spacers, washers, and cap screws. Torque the socket head cap screws
(A) back tightly.
7. Repeat for all the hammers.
