2. Place a straight edge on the outfeed table
and extending over the cutterhead, as
shown in Figure 13.
3. Rock the cutterhead slightly so that a knife
tip contacts the straight edge. If the knife tip
just contacts the straight edge without
moving the straight edge, then the outfeed
table is at the proper height. If the knife tip
pushes up the straight edge, the outfeed
table is too low. If the knife tip does not
contact the straight edge, the outfeed table
is too high.
4. To raise the height of the outfeed table,
loosen the hex nut (B, Figure 12) and rotate
the stop screw (A, Figure 12) clockwise. To
lower the height of the outfeed table, rotate
the stop screw (A, Figure 12) counter
clockwise.
5. When the outfeed table is level with the
knives, tighten the hex nut (B, Figure 12)
and firmly tighten the handwheel (C, Figure
12).
After the outfeed table has been set, it should
not be changed except for special operations.
As a final check of the outfeed table adjustment,
turn on the jointer and run a scrap piece of wood
slowly over the knives for 6 to 8 inches; the
wood should rest firmly on both tables, as
shown in Figure 14, with no open space under
the finished cut.
If the outfeed table is too high, the finished
surface of the workpiece will be curved (Figure
15).
If the outfeed table is too low, the workpiece will
be gouged at the end of the cut (Figure 16).
Make further changes to the stop screw if
necessary to ensure the outfeed table is level
with the knives/inserts.
