12.2 Backgauge Gib Adjustment

If you are having trouble keeping the back-gauge square, check for backgauge side play. Position
the backgauge approximately 2" (50-55mm) from the rear of the table and turn off power.
Remove the rear table cover. From the back, hold each end of the backgauge and try pulling one
end while pushing the other to rock it side to side. If there is noticeable side-to-side play in the
backgauge, the gibs will need adjusting. Check for play at various positions on the table, (Figure 30).
Note: there will be some front to rear movement between the backgauge nut and screw.
The backgauge has two gibs that ride on an iron rail underneath the table, (Figure 31). These are
adjusted with setscrews, which are held in position with jam nuts.
