Adjusting Gibs
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.

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.
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.
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.
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.
