Chipping Knives Sharpening and Replacement
1. The chipping knives should be sharpened or replaced when tree limbs require extra force to feed
into the chipper cone.
2. The chipping knives may be sharpened at a 39 degree angle until the distance between the edge of
the blade bevel and the mounting hole is less than 1/16” (1.6mm). See Figure 13.
To inspect, sharpen, or replace the chipping knives:
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. Remove the rotor by removing the hardware that secures it to the engine crank shaft. See Figure
11.
Note: Do not lose the spacer during reassembly. Be sure the spacer is installed inside the rotor.
Without the spacer, the rotor will interfere with housing components.
5. Using a hex wrench, remove the two socket head cap screws and the chipper knife. See Figure 12.
6. Inspect, rotate, sharpen, or replace the chipper knife. See Figure 13.
7. Reinstall the chipper knife and tighten the socket head cap screws.
