When you receive the jointer, the knives have been pre-set at the factory. However, the height and parallelism of the knives with the outfeed table should be checked, and any needed adjustments made, before putting the jointer into operation.

Proceed as follows:

1.Disconnect jointer from power source.

2.Place a straight edge upon the outfeed table and extending over the center of the cutterhead as shown in Figures 23 and 24.

3.Rotate the cutterhead, using the belt or pulley, until one knife is at its highest point. Do not grab the cutterhead itself to rotate it.

4.Lower the outfeed table until the straight edge contacts the knife, as shown in Figure 24. Using the drive belt, rock the cutterhead slightly to make sure the apex of the knife is contacting the straight edge.

5.Lock the outfeed table at that setting by tightening the locking handle (A, Figure 23).

The importance of the knives being level with the outfeed table are shown by these examples of incorrect settings:

If the outfeed table is too high, the finished surface of the workpiece will be curved. See Figure 25.

If the outfeed table is too low, the work will have a gouge, or snipe, at the end of the cut. See Figure 26.
