To replace the cutterhead knives, do these steps:
1. DISCONNECT JOINTER FROM POWER.
2. Carefully rotate the cutterhead until the clamp
screws are accessible.
3. Remove the cutterhead clamp screws fastening the
knife to the cutterhead (see Figure 41). Carefully
remove the knife and clamp from the cutterhead.
4. Repeat Steps 2–3 for the second cutterhead knife.
5. Clean the cutterhead thoroughly before installing
new knives or re-installing sharpened knives.
6. Install one knife, clamp it in the cutterhead,
and slightly tighten each of the clamp screws in
sequence, as shown in Figure 42.
Note: By tightening the clamp screws out of
sequence, jointing results may be hampered.
Following the tightening sequence reduces that
possibility.
7. Repeat Step 6 for the second cutterhead knife.
8. Check the alignment of the knives to the outfeed
table. They should be parallel to the outfeed table.
— If the knife is not parallel to the outfeed table,
adjust the jack screws to fine tune the knife
height. Refer to Checking/Adjusting Knife Height
on Page 30.
9. Follow the tightening sequence and final tighten
each of the clamp screws for both knives, as shown
in Figure 42.
10. Ensure cutterhead guard is working properly. Align
the fence as needed. Perform a test cut on a
suitable piece of scrap material.

Sharp cutterhead knives provide the best cutting results.
Under normal operation these knives will become
dull and need to be sharpened or replaced. Refer to
Troubleshooting (see Page 28) to determine if the knives
may be dull.
