To adjust/replace the knives:
1. DISCONNECT JOINTER FROM POWER
SOURCE!
2. Remove the cutterhead guard from the table
and move the fence back as far as it will go.
3. Remove the belt guard to expose the
cutterhead pulley.
4. Rotate the cutterhead pulley to get access to
one of the cutterhead knives.
5. Loosen the cutterhead gib bolts, starting in
the middle, and alternating back and forth
until all of the gib bolts are loose, but not fall
-
ing out.
—If this is the first time you are setting the
knives, remove the gib and knife from
the cutterhead. Decide which adjustment
option you are going to use between the
jack screws and the springs.
—If you decide to use the jack screws, remove
the springs from the cutterhead (they are
located directly below the knives).
—If you decide to use the springs, just
thread the jack screws completely into the
cutterhead so they will not get lost. Replace
the gib and knife.
Figure 48. Cutterhead profile diagram.
The Model G0604 comes with both jack screws
and springs inside the cutterhead to provide two
options for adjusting the knives (see
Figure 48).
Note: Only one of these options is needed to set
the knives—see
Step 5 for clarification.
Figure 47. Using knife setting jig to set knife
height.
Knife Setting Jig Method: Both tables are low-
ered to fit the jig on the cutterhead, as shown in
Figure 47, and the knife heights are set to just
touch the middle pad of the jig.
The knife setting jig makes it easy to ensure that
the knives project out of the cutterhead evenly.
After using the knife setting jig to set the knives,
you have to re-adjust the outfeed table height to
ensure that it is even with the knives at their high
-
est point of rotation. If you use the positive stops
on the tables, reset them before operation.
