8.2 Installation of the Ball Screw
1. Install the ball screw assembly as shown in Figure 67. Run the quill up and down over its full travel at each step to
ensure that there is no binding. Adjust as necessary. You can mount a dial indicator on the top of the table, locating off
the ballscrew. Move the knee up and down and tram in the ballscrew from front to back with the leveling nuts.
Note: Loosely install the ball screw at first, and then attach the fork with the quill near the top of its travel.
8.3 Installation of the Motor and Remaining Components

the upper limit switch. The brackets are slotted to allow up and down adjustment. Move the ballscrew
