INCRA Ultra 24 - Manual (Page 19)

Realigning the Carriage
Racks
Remove the carriage from the base and loosen the screws
which hold the racks to the carriage so that they slide easily
along the mounting track.
NOTE: DO NOT alter the position of the carriage clamp or
the micro adjust lever when the carriage is slid out of the
base.
Align the end of rack #1 flush with the rear end of the
carriage and tighten the mounting screws. Position the other
racks on the mounting track with their ends approximately
1
1 /
2
" apart. See Fig. 38. DO NOT tighten the screws for
racks #2 and #3 yet.
Carefully slide the carriage back into the base, taking care
not to change the position of the loose racks. Position the
carriage so that the base is centered approximately between
the ends of racks #1 and #2. See Fig. 39. With the carriage
properly located you should be able to see one of the
mounting screws for each of the two racks. Pull the carriage
clamp up into the "locked " position and the rack on the clamp
will automatically align rack #2 with rack #1. Tighten the
accessible mounting screw on rack #2. Unlock the carriage
clamp and move the carriage forward to tighten the other
mounting screw on rack #2. Now locate the carriage so that
the base is centered approximately between the ends of racks
#2 and #3. Again, "lock" the carriage clamp to bridge the two
racks and tighten the accessible mounting screws on rack #3.
Then "unlock" the carriage clamp and move the carriage
forward to tighten the remaining screw on rack #3.
NOTE: If you have the longer 24" range INCRA JIG ULTRA,
there will be an additional rack #4. If so, use the same
procedure for aligning and tightening these racks that you
used for racks #2 and #3 described above.
