Adjusting Table Parallelism
1. DISCONNECT MACHINE FROM POWER!
2. With wood block still positioned at rear left
corner of conveyor table, locate elevation
leadscrew flange at corner that needs to be
adjusted.
3. Loosen table mounting bolts on flange (see
Figure 80). Rotate flange a small amount to
right to raise or to left to lower that corner of
table until it is within 0.003" of measurement
of wood block from
Step 3 of Checking/
Adjusting Table Parallelism on Page 48.
Note: Each leadscrew flange can be adjusted
up to 0.015" between the right and left sides.
Tip: It may help to rotate elevation leadscrew
flange with a vise grip if it is difficult to move.
5. Repeat Steps 1–4 for any remaining corners
that are not parallel with corner where wood
block is.
— If all corners of conveyor table are exactly
the same distance from upper frame, table
is parallel and no further adjustment is
necessary.
— If any of the corners are still higher or
lower than corner with wood block by
more than 0.003", you will need to adjust
the elevation leadscrew sprocket at that
specific corner of the table. Proceed to
Step 6.
6. Remove lower left access panel.
7. Mark one tooth of sprocket that you are
adjusting, and its location on frame.
8. Loosen chain tensioner sprocket adjustment
nut on sprocket wheel shaft and loosen jam
nut on chain tensioner rod (see
Figure 81).
— If the measurements from all corners in
Step 5 are exactly the same as the length
of the wood block, measured in
Step 3,
the table is parallel to the frame and no
adjustment is necessary. Remove wood
block.
— If the measurement of any corner from
Step 5 is not exactly the same as the
length of the wood block, measured in
Step 3, the table is not parallel to the
frame. DO NOT remove wood block.
Proceed to
Adjusting Table Parallelism.

4. Retighten table mounting bolts to secure
adjustment.
9. Push sprocket adjustment rod toward frame
(or 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. Rotate
sprocket counterclockwise to raise table;
rotate sprocket clockwise to lower table.
