Ball Handles

The ball handles for the X-axis leadscrew have spring-loaded, keyed center bushings, as shown in Figure 8. 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 each end of the X-axis leadscrew.

2.Identify the two ball handles with the spring-loaded center bushings (see Figure 8).

3.For each ball handle, position it so that the protruding part of the center bushing is facing toward the table, align the keyway with the leadscrew key, then slide it onto the X-axis 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 ball handle with leadscrew key, slide the Y-axis ball handle (see Figure 8) 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.
