Assembly

Ball Handles

The ball handles for either end of the X-axis leadscrew have spring-loaded, keyed center bushings, as shown in Figure 9. This allows them to disengage from the leadscrew when using the power feed, avoiding an entanglement hazard.

To install the ball handles:

1.Remove the hex nuts from both ends of the X-axis leadscrew.

2.Identify the two ball handles with the spring-loaded center bushings (see Figure 9).

3.Position the ball handle so that the protruding part of the bushing is facing toward the table, align the keyway with the X-axis leadscrew key, then slide it onto the leadscrew.

4.Secure the ball handles with the hex nuts removed in Step 1.

Note: Tighten the hex nuts just until they are snug. Overtightening could increase the wear of the moving parts.

5.Remove the hex nut from the Y-axis leadscrew.

6.Align the keyway of the remaining ball handle with the leadscrew key, slide the Y-axis ball handle (see Figure 9) onto the leadscrew, then secure it in place with the removed hex nut.

7.Thread the handles into the small end of the ball handles and tighten them with a wrench.
