before shipping. Springs are also included in the cut- terhead supplied with your machine. They may be used instead of the jack screws depending on your preference. Now is a good time to
1.Unplug the jointer!
2.Remove the upper cover or cutterhead guard to expose the top of the cutterhead.
3.Carefully turn the cutterhead (using the pulley) until the first knife is at top dead center.
4.Using the knife setting gauge, check the knife height. The jig should sit solidly with both feet on the cutterhead. See Figure 15. If the knife is adjusted properly, the contact point at the center of each adjuster should just touch the tip of the knife. If the knife does not make contact, or if the knife causes the adjuster’s legs to not seat on the cut- terhead, the knives need to be adjusted.
Remember, jointer knives are extremely sharp. Use care when handling during removing or installing.

ADJUSTMENTS USING JACK SCREWS
When using jack screws, it is not necessary to install the springs. The knives are locked into the cut- terhead with
1.Unplug the jointer!
2.Loosen the gib bolts until the knife is loose in the slot. The gib bolts turn clockwise to loosen and counterclockwise to tighten (when facing the head of the bolt). See Figure 16 and 16B.
3.Place the knife setting gauge on the cutterhead as described previously, so the feet are securely planted on the cutterhead.
4.Adjust the screws below each end of the knife until both feet of the gauge rest evenly on the cutter- head and the knife is just touching the bottom of the middle foot of the gauge. The gauge will set the knives at a uniform protrusion of approximate- ly .070" above the cutterhead. The knife height should vary no more
5.Maintain a constant pressure on the gauge while retightening the gib bolts.
6.Repeat the same procedure on the remaining knives. As mentioned before, the standard knife setting gauge is satisfactory for reasonably accu- rate knife setting tasks.
