7. Adjusting the knife heights:
a. Using a 3mm hex wrench, find the jack
screws through the access holes in the
cutterhead (
Figure 45) and rotate the
jack screws to raise or lower the knife.
When the knife is set correctly, it will
barely touch the bottom of the straight
-
edge or the knife setting jig middle pad.
b. Snug the gib bolts tight enough to just
hold the knife in place.
c. Repeat on the other side of the
cutterhead.
d. Repeat Steps 5–7 with the rest of the
knives.

9. Repeat Step 8.
10. Repeat Step 8, but final tighten each gib
bolt.
11. If you used the knife setting jig to set the knife
heights, use the straightedge to adjust the
outfeed table height evenly with the knives
at top dead center (the highest point in their
rotation). If you used the straightedge to set
the knife heights, skip to the next step.
12. Replace the cutterhead guard, wind the shaft
collar, and tighten the set screws.
13. Close the pulley cover.
8. Rotate the cutterhead to the first knife you
started with. Slightly tighten all the gib bolts,
starting at the ends and working your way
to the middle by alternating left and right
(Figure 46). Repeat this step on the rest of
the knives.
