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 50.

4.Place the straightedge in the positions shown in Figure 51. 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 39

&40) 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.

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 rotated.

The correct order for adjusting the table parallel- ism 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 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 steps involved in checking the outfeed table. Do not continue until you have followed those steps.

To adjust the table parallelism:

1.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 48 (rotate the cutterhead if neces- sary).

2.Remove the set screw from each of the four eccentric bushings (Figure 52) under the outfeed table, and loosen the set screws underneath those removed set screws.
