Crossfeed Screw to Brass Nut & Nut to Carriage (Locking Bolt)
If there is still an excess of backlash after the above adjustments are made, the play will
be either between the crossfeed screw and the brass nut or between the brass nut and
the carriage. The following procedure covers both adjustments at the same time:
1. Remove the crossfeed screw rear support.
2. Loosen the Allen head bolt that locks the brass nut into the carriage.
3. Crank the crossfeed table toward the operator side of the machine. Watch under the
table from the backside and stop before the crossfeed screw comes out of the brass nut.
