Chipping Knives Sharpening and Replacement
The chipping knives should be sharpened or replaced when
tree limbs require extra force to feed into the chipper cone.
The chipping knives may be sharpened at a 30 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 15.
To inspect, sharpen, or replace the chipping knives:
1. Turn the engine o and wait for all moving parts to stop.
2. Disconnect the spark plug wire and secure it away from
the spark plug. SEE FIGURE 12 (page 16)
3. Detach the rotor housing and hopper from the rotor
plate. SEE FIGURE 13
4. Remove the rotor by removing the hardware that secures
it to the engine crank shaft. SEE FIGURE 15
NOTE: Do not lose spacer. During reassembly Be sure
to place spacer is installed inside rotor. Without spacer,
rotor will interfere with housing components.
5. Using a hex wrench, remove the two socket head cap
screws and the chipper knife. SEE FIGURE 16
6. Inspect, rotate, sharpen, or replace the chipper knife.
SEE FIGURE 17
7. Reinstall the chipper knife and tighten the socket head
cap screws to 18-20 ft-lb (24-27 N.m.). We recommend
the use of high strength threadlocker on screws.
