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
.
