Install the table and check its alignment. Make the necessary adjustments, then tighten
the upper and lower bolts.

Front to Back T-Rail and Table Edge/Rail Gap Adjustment
To adjust the front-to-back T-Rail dimensions and table edge/rail gap, do the following:
1.
Remove the upper and lower covers from the left pedestal.
2.
Loosen the four bolts fastening the top of the pedestal and the four bolts fastening the
bottom of the pedestal.
Note:
Before adjusting the distance between the rails, make sure the upper and lower brackets
are securely fastened to the pedestal. Refer to Steps 3 -5 of the previous (Aligning Table)
section and then go to the next step.
3.
Adjust the distance between the T-rails and the table edge/rail gap and tighten the bolts.
4.
Install the pedestal covers that were removed in Step 1.
