Checking Infeed Table
To check the infeed table parallelism:
1.
Follow all the steps for checking the outfeed
table parallelism to first make sure that the
outfeed table is parallel with the cutterhead.
2.
Raise the outfeed table higher than the
cutterhead.
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 54.

4.
Place the straightedge in the positions shown
in Figure 55. In each position, the straight-
edge should sit flat against both the outfeed
table and the infeed table.

infeed/outfeed table parallelism.
—If the straightedge sits flat against both the
infeed and outfeed table, then the tables are
parallel. Set both table heights (Pages 38
& 39) and replace the cutterhead guard.
—If the straightedge does not sit flat against
both the infeed and outfeed table in any
of the positions, then follow the Adjusting
Table Parallelism instructions.

Adjusting Table Parallelism
For safe and proper cutting results, the tables
must be parallel to the cutterhead. Adjusting them
to be parallel is a task of precision and patience,
and may take up to one hour to complete. Luckily,
this is considered a permanent adjustment and
should not need to be repeated for the life of the
machine.
Due to the complex nature of this task, we rec-
ommend that you double check the current table
positions to make sure that they really need to be
adjusted before starting. Refer to the previous two
subsections if you have not just completed them.
The tables have four eccentric bushings under
each corner 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 adjust when unlocked and rotated.
The correct order for adjusting the table parallel-
ism is to first adjust the outfeed table parallel with
the cutterhead, then adjust the infeed table paral-
lel 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 steps below are intended to
be performed in succession with the procedures
for checking the outfeed and infeed tables, begin-
ning on Page 36. DO NOT CONTINUE UNTIL
YOU HAVE FOLLOWED THOSE PROCEDURES
FIRST!
To adjust the table parallelism:
1.
2.
Place the straightedge on the outfeed table
so it hangs over the cutterhead, and lower
the outfeed table until the straightedge just
touches the cutterhead body, as shown in
Figure 52 (rotate the cutterhead if neces-
sary).
Remove the set screw from each of the four
eccentric bushings (Figure 56) under the
outfeed table, and loosen the set screws
underneath those removed set screws.
