Checking Knife Height

1. DISCONNECT JOINTER FROM POWER SOURCE!
2. Place a straightedge on the outfeed table so it extends
over the cutterhead. For best results, use a straight-
edge that will stand on edge without having to be held
in place, as illustrated in Figure 36.
3. Rotate the cutterhead under the straightedge.
— If the knives are parallel to the straightedge,
rotating the cutterhead will move the straightedge
slightly (1/8") forward; no adjustments are
necessary.
— If the knives fall below the straightedge, or if the
knives lift the straightedge and move it more than
1/8" when you rotate the cutterhead, the knives
must be adjusted.

Adjusting Knife height

1. DISCONNECT JOINTER FROM POWER SOURCE!
2. Block the cutterhead guard back so the cutterhead is
fully exposed.
3. Locate the knife clamp screws and knife adjustment
jack screws (see Figures 37–38).
Note: You will perform the procedure in Steps 4–8
for each of the two knives.
4. Use a 4mm hex wrench to loosen the four knife
clamp screws.
5. Adjust the two jack screws until both ends are
sightly below the straightedge.
Checking/Adjusting Knife Height

The knives MUST be level with the outfeed table when
they are at top dead center (their highest point during
rotation) or the workpiece cannot be safely fed across the
jointer.
