*Note: If this is the first time you are setting
the knives, remove the gib and knife from the
cutterhead. Decide which adjustment option you
are going to use between the jack screws and
the springs. If you decide to use the jack screws,
remove the springs from the cutterhead. If you
decide to use the springs, you can just thread the
jack screws completely 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 58 and loosen the gib bolts until the
knife is completely loose.
7. Jack Screws: Using a 3mm hex wrench, find
the jack screws through the access holes in the
cutterhead (see Figure 60) 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 setting 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 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 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. Repeat this step on
the rest of the knives.
9. Final tighten each gib bolt.
10. Adjust the outfeed table to match the new knife
heights (see Page 222).
Calibrating Depth
Scale
The depth scale on the infeed table can be calibrated
or "zeroed" if it is not correct.
To calibrate the depth scale:
1. Set the outfeed table height as described in the
Setting Outfeed Table Height sub-section.
2. Place a straightedge across the infeed and
outfeed tables.
3. Adjust the infeed table until it is level with the
outfeed table, as illustrated in Figure 61.

exactly to "0" (see Figure 62).
