Figure 27 illustrates the correct setting of
outfeed table level with the knives. The
workpiece will rest firmly on both tables with no
open space under the finished cut.
The outfeed table has now been locked at a
standard height, level with the arc of the knives.
NOTE: After the outfeed table has been set at
the correct height, it should not be changed
except for special operations or after replacing
knives.
On the helical cutterhead, after the outfeed
table has been set, no further adjustments will
be needed for the knife inserts. When inserts
are installed properly in the helical cutterhead,
they will automatically be set at the proper
position.
On the standard cutterhead, further fine
adjustments will now be achieved by adjusting
the knives in the cutterhead. Proceed as follows.
7. Lower the infeed table out of the way, by
loosening the locking handle (A, Figure 28)
and pushing down on the adjustment arm
(B, Figure 28).
8. An aluminum knife setting gauge, shown in
Figure 29, is provided with the jointer. If you
require very fine tolerances when setting the
knives, a knife setting gauge with a dial
readout can be purchased. The provided
aluminum gauge should,
accurate enough for most woodworking
needs.
9. Place the provided knife setting gauge at
the back of the outfeed table (toward the
fence support side) and extending over the
cutterhead as shown in Figure 29. Place the
gauge so that the right mark lines up with
the edge of the outfeed table, as shown.
10. Rotate the cutterhead clockwise (by using
the pulley). If table and knives are set
correctly, the knife will contact the aluminum
gauge and move the gauge until the left
mark now lines up with the edge of the
outfeed table, as shown in Figure 30.
11. Place the aluminum knife gauge at the front
of the outfeed table (toward the rabbet
ledge) and repeat the process.
12. This test should be performed on all three
knives in the cutterhead, using the provided
gauge.
13. If any knife is either too high or too low at
one of its ends to correctly move the gauge
as described above, then the height and/or
parallelism of that knife in the cutterhead
needs to be adjusted. Proceed as follows.
