Table Parallelism Inspection

Use your Rotacator to inspect the table parallel- ism. If you do not have a Rotacator, a wood block and feeler gauges may be used, but extra care must be taken to ensure accuracy. If the table is not within the maximum allowable tolerances, it must be adjusted.

Table Parallelism Adjustments

The table is adjusted by turning the chain sprock- ets underneath the table for movements over 0.016" or by adjusting how the table is mounted on the columns for movements under 0.016".

NOTICE

When making adjustments, tighten fasten- ers after each step to ensure the accuracy of your tests. When adjusting the chain sprockets, keep in mind that if the chain becomes too loose, it will fall off of all the sprockets. Returning it to its proper loca- tion can be frustrating.

To adjust the table parallelism:

1.DISCONNECT THE PLANER FROM THE POWER SOURCE!

2.Remove the cabinet panel and locate the chain on the underside of the table.

3.Loosen the idler sprocket (see Chain Tension instructions on Page 25).

4.Move the chain away from only the sprocket you want to adjust so only that sprocket can be turned independent of the chain.

Note: If the left side of the table is too high, the left two sprockets will need to be adjusted. Each tooth on the sprocket represents .016" of vertical movement as the cogs are turned. Make sure, as you turn the sprockets, to keep an accurate tooth count to ensure that the table is adjusted equally.

5.Mark the location of one tooth in the sprocket that you are adjusting.

6.Carefully turn the sprocket (clockwise to lower the table; counterclockwise to raise the table) just enough to position the next tooth at the marked location, then fit the chain around sprocket again.

7.Repeat Steps 4–6with each sprocket that needs to be adjusted until the table-to- cutterhead clearance is within 0.016" from one side to the other.

8.Make sure the chain is properly fitted on the sprockets and tighten the idler sprocket and lock bolts.

9.Micro-adjust the table position by loosening the cap screws shown in Figure 27 and lifting the table upward or downward until the table and cutterhead are in alignment.

Note: This process may require adjusting the columns on both the left and right hand sides until you find the correct combination.
