the jack screws, remove the springs from the cutterhead. If you decide to use the springs, you can just thread the jack screws com- pletely into the cutterhead so they will not get lost. Replace the gib and knife.
6.Position the knife gauge over the knife as shown in Figure 53 and loosen the gib bolts until the knife is completely loose.
Figure 53. Jig placement on cutterhead.
7.Jack Screws—Using a 3MM allen wrench, find the jack screws through the access holes in the cutterhead (Figure 54) and rotate the jack screws to raise or lower the knife. When the knife is set correctly, it will barely touch the middle pad of the knife set- ting jig. Snug the gib bolts tight enough to just hold the knife in place. Repeat steps 5- 7 with the rest of the knives.

Springs—Push the knife down with the jig so that the knife edge is touching the middle pad of the jig. Hold the jig down and tighten the gib bolts just tight enough to hold the knife in place. Repeat steps 5-7 with the rest of the knives.
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. Repeat this step on the rest of the knives.
9.Repeat step 8.
10.Repeat step 8, but final tighten each gib bolt.
Adjusting Gibs
The function of the table gibs (shown in Figure 55) is to eliminate excessive play in the table movement. The gibs also control how easy it will be to move the tables up and down.
Figure 55. Table gibs.
To adjust the table gibs:
1.Loosen the table lock.
2.Loosen the lock nuts and setscrews shown in Figure 56 on the next page. Make sure you support the table as you loosen it to prevent it from dropping to the end of its travel.
