Setting the knives correctly is crucial to the proper operation of the jointer and is very important in keeping the knives sharp. If one knife is higher than the others, it will do the majority of the work, and thus, dull much faster than the others.
The knife gauge included with the jointer is designed to set the knives at 0.063" (1/16"), which is the correct distance all the knives should pro- trude above the cutterhead.
The Model G0656 comes with jack screws for cutterhead adjustments (see Figure 52).

5.Carefully inspect how the gauge touches the cutterhead and the knife.
—If both outside legs of the gauge sit firmly on the cutterhead and the middle pad just touches the knife, then that knife is set correctly. (Repeat this inspection with the other knives.)
