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 double-check the
knife settings. To inspect and adjust knife set:
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 wedge-type gibs and gib bolts. Jack
screws under the knives allow fine tuning to help in the
setting process. To realign the knives:
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 than .002"-.003" across the
length of the cutterhead.
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.
Figure 15 shows the location of the springs
should you decide to use them instead of jack
screws.
