4.
Tighten table mounting bolts to secure
adjustment.
5.
Repeat Steps 1–4 for any remaining corners
that are not parallel with wood block corner.
— If all corners of conveyor table are exactly
same distance from upper frame, table
is parallel and no further adjustment is
necessary.
— If any of corners are still higher or lower
than corner with wood block by more than
0.003", you will need to adjust the eleva-
tion leadscrew sprocket at that specific
corner of the table. Proceed to Step 6.
6.
Open both lower access panels.
7.
Mark one tooth of sprocket (see Figure 99)
that you are adjusting, and its location on
frame.

9.
Push sprocket adjustment rod toward frame
(away from you) to loosen chain tension.
10. Remove chain from sprocket you want to
adjust so only that sprocket can be moved
independent of chain.
11. Carefully rotate sprocket just enough to posi-
tion next tooth at marked location from Step 7,
then fit chain around sprocket again.
Note: Rotate sprocket counterclockwise to
raise table; rotate sprocket clockwise to lower
table.
12. Pull chain tensioner rod toward you, tight-
en jam nut until chain is moderately tight,
then tighten sprocket nut to secure (see
Figure 100).
13. Check table parallelism (refer to Checking
Table Parallelism on Page 55) and, if nec-
essary, repeat Steps 2–12 until all corners
of table are the same distance from upper
frame.
14. Remove wood block and close lower access
panels.
