On the side of the outfeed (gold) carriage you’ll notice (4)
sawtoothed INCRA racks. To realign these racks, loosen
the phillips head screws that hold the forward (3) racks in
place. Do not loosen the screws on the rack at the rear
end of the carriage. Position the carriage in the base so
that when the carriage clamp is pulled up into the locked
position, the short clamping rack bridges the gap between
the already tightened rear rack and the second rack. See
Fig. 33. Tighten the one mounting screw you have access
to. Then unlock the carriage clamp and slide the carriage

forward to tighten the other screw. Continue with this
bridging and tightening operation between racks #2 and
#3, then finally between #3 and #4.
Realign the fence racks in the same way that the
carriage racks are aligned. Leave one of the two racks
on each fence in place while loosening the screws on the
other. Bridge the gap between the loosened and
tightened racks using the INCRA Stop, then tighten the
two screws on the loose rack.
Loosen the (4) socket head cap screws that secure the
infeed fence mounting bracket to the infeed (black)
carriage, Fig. 34. Using a reliable straightedge, hold both
the infeed and outfeed fences against the straightedge and
tighten the (4) screws a little at a time until all are secure.
Adjusting the fences square to the table is done by
loosening the same (4) socket head cap screws and
placing shims between the fence mounting bracket and
carriage. Fence squaring adjustments may be performed
as necessary to one or both fences.
First:
Loosen screws on forward 3 racks
Second:
Position carriage so that short clamping rack bridges
ends of rear and second rack, then clamp in place
Approx. 5 / 1 6 "
Do not loosen screws on rear rack
