FEED ROLLER AND CHIP BREAKER ADJUSTMENTS
Figure 18 shows the relationship of the feed rollers and chipbreaker to the lowest point of the cutting circle. As shown
in the diagram, both the infeed roller, outfeed roller and chip breaker should all be 0.02” below the lowest point of the
cutting circle.
TO BEGIN
To begin, place a 0.02” feeler guage on top of the guage
block as shown in Figure 19. Raise the table so that the
feeler guage just scrapes the bottom of the knife at its
lowest point of the cutting circle. To find the lowest point,
turn the cutterhead by hand. This is easily done by
removing the belt guard and turning the cutterhead with
the v-belts. Once the lowest point of the cutting circle is
found, do not change the height of the table until after all
the adjustments are made
