I have the same jointer, just did the adjustment this past weekend.
My table was out by a 5thou sag on the infeed, toward the operator.

Adjustment is via set screws on the infeed table, accessible after
removing the bottom plate.
Look for 4 hex head bolts situated around the motor (motor/belt removal
not req'd)
Loosen whatever bolt is located at desired adjustment point, then move
the set screw to adjust and tighten the bolt back up onto the now
adjusted set screw.
Got mine to within about 2thou.
Now if I could just get the knives out.......but that is an earlier
post.
