7. Adjusting the knife heights:
Jack Screws: Using a 3mm hex wrench, find
the jack screws through the access holes in the
cutterhead (see Figure 58) 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 straightedge or the knife setting jig mid-
dle pad (depending on which method you are
using). Snug the gib bolts tight enough to just
hold the knife in place. Repeat on the other side
of the cutterhead, then repeat Steps 5–7 with
the rest of the knives.

Springs: Push the knife down with the straight-
edge or middle pad of the knife setting jig, keep-
ing the straightedge flat against the outfeed
table or the knife setting jig feet evenly against
the cutterhead (depending on which method
you are using). Tighten the gib bolts just tight
enough to hold the knife in place. Repeat on the
other side of the cutterhead, then repeat Steps
5–7 with the rest of the knives.
8. Rotate the cutterhead to the first knife you start-
ed with. Slightly tighten all the gib bolts, starting
at the ends and working your way to the middle
by alternating left and right (see Figure 53).
Repeat this step on 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 and the close the
back cover.
