Adjusting Table Parallelism
For safe and proper cutting results, tables must
be parallel to cutterhead. Adjusting them to be
parallel is a task of precision and patience, and
may take up to one hour to complete. This is 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
recommend that you double check current table
positions to verify that they need to be adjusted
before starting.
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 set screws and adjust when rotated.
The correct order for adjusting the table
parallelism is to first adjust the outfeed table
parallel with the cutterhead to within 0.010"-
0.012", 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 inserts.
Checking Infeed Table
1.
Follow all steps for checking outfeed table
parallelism to make sure that outfeed table
is parallel with cutterhead.
2.
Raise outfeed table higher than cutterhead.
3.
Loosen infeed table jam nuts and positive
stop bolts shown in Figure 36.
5.
Place straightedge in positions shown in
Figure 38. In each position, straightedge
should sit flat against both outfeed table and
infeed table.
— If straightedge sits flat against both
infeed and outfeed table in each positions,
then tables are parallel. Set both table
heights (Pages 40–41) and replace
cutterhead guard.
— If straightedge does not sit flat against
both infeed and outfeed table in any
positions, then follow Adjusting Table
Parallelism.
4.
Place straightedge halfway across infeed
table and halfway over outfeed table, and
adjust infeed table even with outfeed table,
as shown in Figure 37.
