To adjust the X-axis leadscrew:
1. Locate the X-axis leadscrew adjuster shown in Figure 61 under the middle of the table. The head on the adjustment screw faces to the right.

3. Test the adjustment by turning one of the side handwheels. You should detect less than 0.008" of play.
To adjust the Y-axis leadscrew:
1. Locate the adjuster midway along the Y-access leadscrew, inside the base. This adjuster can be accessed by reaching under the way cover just behind the table.
2. Tighten the adjustment screw and test the adjustment in the same manner as you did for the X-axis leadscrew.

4.Put on gloves and pull the spring cover out enough so the notches just clear the roll pin. HOLD THE SPRING COVER TIGHTLY or the force of the spring will spin it out of your hands.

5.Rotate the cover to adjust the tension. Push the cover back in to engage the roll pin in one of the notches, as shown in Figure 60.

Leadscrew Backlash

When you turn the handwheels to adjust the posi- tion of the table, you will notice slight play (back- lash) in the handwheel before the table begins to move. If this play is greater than 0.008" (measured with the dial at the base of each handwheel), then you will need to adjust the leadscrews.

Make adjustments in small increments. Over- tightening to attempt to reduce backlash to less than 0.003" is impractical and will add unneces- sary wear to both the leadscrews and the adjust- ers.
