6. Torque the nuts to 180 foot pounds (244
Nm) beginning with the center bolt. Re-check
the torque on all the nuts after the last nut is
tightened. Do not overtorque the nuts.
Overtightening the bolts will also cause the knife
to crack from the hole out. If a knife has been
overtightened, it may have distorted the knife around
the hole.
Place a straight edge along the holes and hold it up
to a light. You should not be able to see any distortion
of the knife. If you see any distortion, do not use the
knife. This could allow wood to pack between the knife
and the cutter disc, causing the knife to fail, or the
mounting bolts to elongate or break.
7. Repeat steps 4 - 6 for the second knife.
8. After both knives are changed, the knife bed
will need to be adjusted. Refer to the following
section for the correct procedure.

other tightening.
when turning, flipping, or replacing a bed knife,
all surfaces should be cleaned of debris, and
inspected for deformities. If this inspection/
cleaning is not performed, knife bed bolts could
loosen, leading to catastrophic damage.
