6. Rotate the cutterhead with the V-belt pulley so
one of the knives is at BDC as shown in Figure
54.
7. Use your Rotacator to find bottom dead center
(BDC) of any knife/insert edge by slowly rock-
ing cutterhead pulley back and forth, then set
Rotacator dial to "0" (see Figure 54).
8. Keeping Rotacator dial at "0", position it under
right-hand side of infeed roller (see Figure 54)
and find BDC of a serrated edge.

10. Repeat Steps 8–9 on left-hand side of infeed
roller.
11. Re-check both sides of infeed roller and, if nec-
essary, make further adjustments until infeed
roller height from side-to-side is 0.040" below
BDC of cutterhead knife/insert, then re-tighten
both jam nuts.
12. Keeping same "0" reference on Rotacator dial
from Step 7, repeat Steps 8–9 for outfeed roll-
er, but adjust it until it is 0.020" below BDC of
cutterhead knife/insert.
13. Using same "0" reference on Rotacator dial from
Step 7, perform similar steps as described above
to adjust height of chip breaker to its recom-
mended specification given at beginning of this
subsection. The adjustment controls are shown
in Figure 56.
9. Loosen jam nuts and use set screws on each side
of feed roller (see Figure 55) to adjust height of
infeed roller bushing block until Rotacator dial
shows 0.040", which is the recommended dis-
tance for infeed roller below cutterhead.
