4. Rotate the cutterhead, using the drive belt or
pulley, until knife number one is at its
highest point. The apex of the knife should
just barely come in contact with the
straightedge.
If the apex of the knife number one just
makes contact with the straightedge, no
adjustment is required for the outfeed table.
Proceed to the Setting Cutterhead Knives
section.
If the apex of the knife number one comes
below the straightedge (a gap exists) or
pushes the straightedge up, proceed with
the following steps:
5. Loosen both gib lock screws (B, Fig. 8-8)
and the lock knob (Figure 8-9).
6. Raise or lower the outfeed table until the
straight edge contacts the knife tip, as
shown in Figure 8-10. Using the drive belt or
pulley, rock the cutterhead slightly to make
sure the apex of the knife is just barely
contacting the straight edge.
When adjustment is complete:
7. Lock the outfeed table at that setting by
tightening the lock knob (Figure 8-9) and gib
lock screws (B, Fig. 8-8). The outfeed table
adjustment is complete.

The outfeed table adjustment is only made
against one knife (blade number one was
arbitrarily selected here). After the outfeed table
has been set at the correct height, do not
change it except for special operations or after
replacing knives.
After this adjustment is completed, it is
necessary to proceed to the Setting Cutterhead
Knives section to verify that all three knives are
at the correct height and parallel to the outfeed
table.
8.7 Setting cutterhead knives (JJ-
6CSDX)
Note: Before setting knives for model JJ-6CSDX
Jointer, the Outfeed Table Adjustment should be
done to ensure the proper knife height in relation
to the outfeed table.
Knives for the JJ-6CSDX
adjusted by means of a cam. It is important to
note that the entire adjustment is accomplished
within one complete rotation (360 degrees) of
the cam. A full rotation of the cam will cause the
knife blade to move a total of .015" from one
extreme to the other. Turning the cam more than
one full rotation will not further adjust the knife
setting, but will simply begin the adjustment all
over again. The knife adjustment procedure is
outlined below.
dangerously sharp. Use extreme caution
when inspecting, removing, sharpening or
replacing knives into the cutterhead. Failure
to comply may cause serious injury.
To adjust (refer to Figures 8-11 & 8-12):
1. Disconnect jointer from power source.
2. Carefully number each blade with a marker
to make them easier to differentiate.
3. Place a straightedge across the outfeed
table extending it over the cutterhead
towards one end of the knife.

cutterhead itself to rotate it! Failure to
comply may cause serious injury.
4. Rotate the cutterhead back and forth using
the drive belt or pulley, until knife number
one is at its highest point. The apex of the
knife should just barely come in contact with
the straightedge.
5. Move the straightedge towards the other
end of the knife and repeat step 4.
The apex of the knife at both ends of the
knife must just make contact with the
straightedge. If the apex of the knife comes
