2. Remove the cutterhead guard from the table
and lower the infeed and outfeed tables as
far as they go. This will give you unrestricted
access to the cutterhead.
3. Remove the rear access panel to expose the
cutterhead pulley.
4. Rotate the cutterhead pulley to give you good
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, or if you are replacing them, remove
a gib and knife from the cutterhead. Clean
the gib and clean inside the cutterhead
slot to remove all pitch or sawdust. Coat
the knife and gib with a metal protectant
(

6. Position the knife gauge over the knife as
shown in Figure 51 and loosen the gib bolts
until the knife is completely loose.
7. Using a 2.5mm hex wrench, find the jack
screws through the access holes in the
cutterhead (
Figure 53) and rotate the jack
screws to raise or lower the knife. When the
knife is set correctly, it will barely touch the
middle pad of the knife setting jig. Snug the
gib bolts tight enough to just hold the knife in
place. Repeat
Steps 5-7 with the rest of the
knives.
Figure 53. Jack screw access hole.
8. Rotate the cutterhead to the first knife you
started with. Slightly tighten all the gib bolts,
starting at the middle and working your
way to the ends by alternating left and right
(
Figure 54). Repeat this step on the rest of
the knives.
9. Repeat Step 8, but final tighten each gib
bolt.
10. Adjust the outfeed table to match the new
knife heights (refer to Setting Outfeed Table
Height, Page 17).
11. Replace the cutterhead guard and the rear
access panel.
