Installing the Type II Headstock
Before proceeding, refer to the system layout drawings to ensure precise
set up location.
Refer to
and proceed as follows:
1. Set the column assembly in desired position.
2. Use leveling bolt holes as a guide and transfer the hole locations to the
concrete.
3. Remove column assembly.
4. Install the anchors per the manufacture’s instructions.
5. Install a leveling shim at each anchor location and reset the column
assembly.
6. Screw each leveling bolt down until it just contacts the leveling shim
and hand tighten the anchor bolts or nuts.

4.3.3.2
Leveling the Type II Headstock
The headstock must be leveled in two directions;
• Parallel to the faceplate
• Perpendicular to the faceplate.
Since it only takes three points to define a plane, use only three of the six
leveling bolts to level the positioner. It is important to consistently use the
same three leveling bolts throughout each process. The other three
leveling bolts will be used as anchors only.
Before proceeding, make sure that the headstock is in the proper place.
Make sure a leveling bolt, lock-nut, and leveling shim is installed in each
column base hole.
To level the headstock assembly axially, proceed as follows:
1. Place a level on top of the housing, perpendicular to the faceplate.
2. Use the two leveling bolts beneath the faceplate (A and B), and a third
beneath the motor (C) to level axially. If the faceplate side needs
adjustment, A and B must be turned equally.
