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.
