6.12 Rotor Blades
The rotor is equipped with four offset, evenly-spaced blades. If
a blade needs to be changed, the one opposite should also be
changed to keep the rotor balanced.
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. 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).
2. Remove the bolt that secures the upper rotor housing, and
carefully open the rotor housing.
CAUTION!
Avoid reaching into the rotor housing. The
rotor and ledger knives are very sharp. If it is
necessary to reach into the rotor housing, set the
machine to a safe condition, wear heavy gloves,
and use extreme caution.

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.
