3. Find a straight rod between 8 in. and 12 in. (203 mm and 305 mm) long. Verify that it's straight: roll it on a
known flat surface (like a granite surface plate).
Note: You'll use the rod to verify that the ATC is correctly installed on the mill, so it must be
straight.
4. Put the alignment rod into a tool holder.
5. Put the tool holder into the fork so that the groove in the tool holder slides into the fork, and so that the
drive slot aligns with the dog. Don't rest the tool holder on top of the fork.
6. Put a machinist's square on the machine table.
Examine Perpendicularity in the Y Direction
1. Verify that the rod is perpendicular to the machine table in the Y direction: compare the rod's position to the
vertical edge of the machinist's square.
lIf the rod is perpendicular to the vertical edge of the machinist's square, go to "Examine
Perpendicularity in the X Direction" (on the next page).
lIf the rod must be adjusted, go to Step 2.
2. Loosen the flange nuts on the standoffs.
3. Turn the tilt standoff with an adjustable wrench, and slowly pivot the ATC until the rod is perpendicular to
the vertical edge of the machinist's square.
Figure 9: Tilt standoff.
4. Tighten the flange nuts with a 13 mm socket.
5. Reexamine the alignment of the ATC in the Y direction. If the rod isn't perpendicular to the vertical edge of
the machinist's square, repeat Steps 2 through 5.

2. Loosen the two socket head cap screws on the linear rails.
Figure 10: Socket head cap screws on the linear rails.
3. Slowly pivot the linear rails up or down until the rod is perpendicular to the vertical edge of the machinist's
square.
4. Tighten the socket head cap screws.
5. Reexamine the alignment of the ATC in the X direction. If the rod isn't perpendicular to the vertical edge of
the machinist's square, repeat Steps 2 through 5.
Examine the Alignment of the Carousel Door Opening
1. Remove the tool holder from the fork, and set it aside.
Note: You'll need this tool later in the installation procedure to make further alignments.

examine the clearance of the carousel door opening.
4. Verify that the carousel door opening is approximately equal to the front back and left of the spindle
mounting flange:
lIf the carousel door opening is approximately equal, go to Step 8.
Figure 11: Distance between the carousel door opening and the spindle mounting flange.

5. Loosen the four socket head cap screws that secure the ATC main assembly to the mounting bracket with a 6
mm hex wrench.
Figure 12: Socket head cap screws securing the ATC main assembly to the mounting bracket.
6. Adjust the carousel door opening as required:
lIf the Carousel Door Opening is Contacting the Front Pivot the ATC around the locating pin on
the bottom of the mounting bracket toward the front of the machine (closer to you).
lIf the Carousel Door Opening is Contacting the Back Pivot the ATC around the locating pin on
the bottom of the mounting bracket toward the back of the machine (closer to the machine column).
lIf the Carousel Door Opening is Contacting the Left Loosen the four flange nuts that attach the
mounting bracket to the column to move the bracket forward or backward.
Note: Moving the ATC mounting bracket could change the position of the tilt standoff (on the
Z-column). If you move it, you must verify that the ATC is still correctly installed; go to
"Examine Perpendicularity in the Y Direction" (page11).
Repeat this step as needed.
7. Tighten the socket head cap screws and the flange nuts (if you loosened them in Step 5).
