7.6.2 Rotor Blade Maintenance:
The rotor and ledger blades need to be sharp for the Chipper to
perform as expected. Periodic inspection is recommended. Keep
the blades sharp to reduce the amount of power required during
operation. Watch the sharpness of the blades when processing
material with a lot of sand, soil or dirt mixed with it. Reverse or
sharpen the blades if the cutting edge becomes dull.
Rotor Blades:
The rotor is equipped with 2 blades (BXT4213, BXT4224) or 4
blades (BXT6224, BXT6238) spaced evenly to keep the rotor in
balance. If one needs to be changed, the one opposite should
also be changed.
It is recommended that the rotor blades be removed from the
rotor when sharpening. Always sharpen the blades at a 45°
angle to provide the best cutting effect as it meets the stationary
blade. Be sure to tighten the blade mounting bolts to their
specified torque when re-installing the blades to the rotor.

1. Ensure the engine is off (ignition switch is off and the fuel
valve is closed).
2. Remove the bolt that secures the upper rotor housing, and
carefully open the rotor housing.
3. Manually rotate chipper rotor plate so that the blade is fully
exposed
4. Remove the bolts that hold the rotor blade to the rotor,
remove the blade.
5. Rotate the blade and reinstall or replace with new or
re-sharpened blade.
6. Ensure the blade is properly oriented, with the leading edge
out. The blade is designed to fit into the rotor one way only.
See diagram for proper installation.
7. Tighten down bolts as specified in the torque chart
8. Repeat steps for second blade.
