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.
Knee Crank
Slide the knee crank onto the shaft so that the
teeth of the crank and shaft engage, as shown in
Figure 10.
