3. Place the straightedge halfway across the infeed
table and halfway over the outfeed table, and adjust
the infeed table even with the outfeed table, as
shown in
Figure 53.
4. Place the straightedge in the positions shown in
Figure 54. In each position, the straightedge should
sit flat against both the outfeed table and the infeed
table.
— If the straightedge sits flat against both the infeed
and outfeed table, then the tables are parallel.
— If the straightedge does not sit flat against both the
infeed and outfeed table in any of the positions,
then the infeed table needs to be adjusted parallel
with the outfeed.
Adjusting Table Parallelism
For safe and proper cutting results, the tables must be
parallel with the cutterhead. Adjusting them to be paral
-
lel is a task of precision and patience, and may take up to
one hour to complete. Luckily, this is considered a perma
-
nent adjustment and should not need to be repeated for
the life of the machine.
Due to the complex nature of this task, we recommend
that you double check the current table positions to make
sure that they really need to be adjusted before starting.
The tables have four eccentric bushings under each cor
-
ner that allow the tables to be adjusted parallel. These
eccentric bushings are locked in place by piggybacked set
screws (one on top of the other) and adjusted when the
eccentric bushing is rotated.
The correct order for adjusting the table parallelism
is to first adjust the outfeed table parallel with the
cutterhead, then adjust the infeed table parallel with the
outfeed table.
When setting the outfeed table, all measurements must
be made from the cutterhead body—not the knives—or
results may get skewed the next time you change knives.
IMPORTANT: The next steps are intended to be per
-
formed in succession with the same steps for checking the
outfeed table. Do not continue until you have followed
those steps.
