To adjust/replace the knives:
1. DISCONNECT JOINTER FROM POWER
SOURCE!
2. Loosen the set screws shown in Figure 10,
Page 17, remove the cutterhead guard, and
move the fence back as far as it will go.
3. Open the pulley cover 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.
6. Remove and clean the gibs and clean inside
the cutterhead slot to remove all pitch or saw-
dust. Coat the knives and gibs with a metal
protectant (
Page 27), then fit the gibs back in
the cutterhead with the new knives.

The Model G0609 comes with jack screws inside
the cutterhead to adjust the knives (see
Figure
44).
Figure 43. 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 43, 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 are using the positive
stops on the tables, they will need to also be reset
before operation.
