Work Table Parallel to Cutterhead

The work table is set parallel to the cutterhead at the factory and no further adjustment should be necessary. If your machine is planing a taper, first check to see if the knives are set properly in the cutterhead. Then check to see if the work table is set parallel to the cutterhead. Proceed as follows:

1.Disconnect machine from power source.

2.Place the gauge block (Figure 21) on the work table directly under the edge of a knife as shown. Make slight contact by gently raising table.

3.Move the gauge block to the opposite end of the work table. NOTE: Distance from the work table to edge of knife should be the same.

4.If the work table is not parallel to the cutterhead, perform the adjustment procedure as follows.

5.Remove bolts holding the planer to the stand. Carefully tilt planer on its side to expose underside of base (Figure 22).

6.Remove bolt (A, Figure 22) and loosen bolt (B, Figure 22) which will allow you to move the idler sprocket assembly (C, Figure 22) far enough to release tension on the chain.

7.Remove the chain from the particular sprocket on the corner of the base that you need to adjust.

8.Turn the sprocket by hand to bring that corner into adjustment with the other three corners. NOTE: Turning sprocket clockwise will increase the distance between the working table and the head casting; counterclockwise will decrease the distance. This adjustment is very sensitive and it should not be necessary to turn the sprocket more than one or two teeth.

9.When adjustments are correct, replace chain around corner sprocket, slide idler sprocket (C, Figure 22) back to re-tension chain, tighten bolt (B, Figure 22) and insert and tighten bolt (A, Figure 22).
