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.

  Remove the hex nuts from both ends of the 

X-axis leadscrew.

  Identify the two ball handles with the 

spring-loaded center bushings (see 
Figure 9).

  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.

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

 Tighten the hex nuts just until they are 

snug. Overtightening could increase the 
wear of the moving parts.

  Remove the hex nut from the Y-axis 

leadscrew.

  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.

 

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

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