Adjusting the Indexing Pins
If it appears that the pins are out of alignment, you can straighten them out by
drilling a test board and realigning a Pin in one of the drilled holes. Follow the
testing procedure to confirm that they are out of alignment.
ƒ Use a scrap of at least two feet in length and cut a set of holes with the
front Drop Gauge down.
ƒ Slide the board over so that either the left or right Index Pin can enter one
of the holes that you just drilled.
ƒ Cycle the machine, insuring that the Index Pin is firmly in the hole before
bringing the head down.
When drilling, the bits should re-enter the holes without chipping out the edges or
kicking the board out. If either of these things happens then the Index Pins need to
be re-calibrated.
ƒ To adjust an Index Pin loosen the two bolts holding the Index Pin bracket
in place.
ƒ Use a piece of board to cut a full row of holes in. Make sure that there
isn't much sawdust remaining in the holes.
ƒ Slide the board over so that the Index Pin will enter the last hole, but still
leave the majority of holes underneath the head.
ƒ Bring the head down into the previous holes while watching very closely
that the bits are entering in the exact center.
ƒ While the head is down place the Index Pin into the hole (if not already
there), and tighten the nuts on the bracket.
