This machine comes with jack screws for cut-
terhead adjustments.
TO SET OR REPLACE THE KNIVES:
1. DISCONNECT JOINTER FROM POWER!
2. Remove the cutterhead guard from the ta-
ble 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 un-
til all of the gib bolts are loose but not falling
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 re-
move all pitch or sawdust. Coat the knife and
gib with a metal protector.
6. Position the knife gauge over the knife as
shown in Figure 58 and loosen the gib bolts
until the knife is completely loose.
7. Using a 2.5 mm hex wrench, rotate the jack
screws (Figure 58) in the access holes 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.

8. Rotate the cutterhead to the first knife you
adjusted. Slightly tighten all the gib bolts, start-
ing at the middle and working your way to the
ends by alternating left and right (Figure 59).
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).
11. Replace the cutterhead guard and the rear
access panel.

brated or "zeroed" if it is not correct.
To calibrate the depth scale:

Setting Outfeed Table Height.
2. Move the cutterhead guard out of the way.
3. Place a straightedge across the infeed and
outfeed tables.

the outfeed table, as illustrated in Figure 60.
