controls for the feed rollers and the chip
breaker are backed off enough so that they
will allow the components to move below
the current position on the board.

where you can measure the cutterhead
body movement as shown in Figure 30.
10. Raise the cutterhead body 0.020" as
indicated by the Rotacator®or a dial
indicator. The feed rollers and the chip
breaker should all move freely with the
table. If they do not, make sure that they
are all resting evenly on the boards at this
current position.

lock the chip breaker in place. It should
now be set at 0.020" below the knife edge
when the knife is at bottom dead center.
12. Continue raising the cutterhead body
another 0.020" as indicated by the
Rotacator® or a dial indicator. The outfeed
and infeed rollers should now be set to
approximately 0.040" below the knife edge
at bottom dead center. Lock the outfeed
and infeed rollers in place.
13. Re-install the belt cover.
