Model G0704 (Mfg. Since 08/11)
Figure 57. X-axis leadscrew adjusters.
Leadscrew Backlash
Digital Readout Unit
Battery Replacement
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 leadscrew nuts.
To reach the adjustment screws on the leadscrew
nut, you may have to fabricate extensions for
your hex wrenches. When adjusting, make adjust-
ments in small increments. Attempting to reduce
backlash to less than 0.003" is impractical and
will add unnecessary wear to both the leadscrews
and the leadscrew nuts.
To adjust the X-axis leadscrew:
1. Locate the X-axis leadscrew nut under the
middle of the table. The head on the adjust-
ment screws face to the right (Figure 57).
To adjust the Y-axis leadscrew nut:
1. Locate the leadscrew nut underneath the
table through the hole in the base under the
rubber way cover.
2. Tighten the adjustment screws on the
leadscrew nut in the same manner as
described for the X-axis leadscrew adjust-
ment.
3. Test the adjustment by turning one of the
cross handwheels. The ideal amount of play
when properly adjusted is 0.003"–0.006".
2. Tighten the adjustment screws.
3. Test the adjustment by turning one of the
longitudinal handwheels. The ideal amount
of play when properly adjusted is 0.003"–
0.006".

Battery Cover
If the digital readout unit stops functioning, the
battery must be replaced.
To replace the digital readout unit battery:
1. Use a wide (#3) standard screwdriver or the
edge of a coin to remove the battery cover
(Figure 58).
2. Remove the old battery, dispose of it accord-
ing to state and federal regulations, then
replace it with a new one.
3. Replace the battery cover.
