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 falling
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.
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 32), then fit the gibs back in
the cutterhead with the new knives.
7. Adjusting the knife heights:
Knives are sharp! When adjusting knives,
wear gloves or cover knives with rags to
avoid contact with knives, which could
cause serious personal injury.
To adjust/replace the knives:
1. DISCONNECT THE JOINTER/PLANER
FROM THE POWER SOURCE!
2. Remove the cutterhead guard from the table,
and flip up the lower the infeed and outfeed
tables. This will give you unrestricted access
to the cutterhead.
3. Remove the motor access panel to expose
the motor pulley.
4. Rotate the motor pulley to give you good
access to one of the cutterhead knives.
Jack Screws: Using a 3mm hex wrench, find
the jack screws through the access holes in
the cutterhead (
Figure 62) and rotate them
to raise/lower the knife. When the knife is
set correctly, it will barely touch the middle
pad of the knife setting gauge. For now, only
tighten the gib bolts enough to hold the knife
in place. Repeat Steps 5–7 with the other
knives.
Figure 62. Jack screw access hole.
Springs: Push the knife down with the gauge
so that the knife edge is touching the middle
pad of the gauge. Hold the gauge down and
only tighten the gib bolts enough to hold the
knife in place. Repeat
Steps 5–7 with the
other knives.
8. Rotate the cutterhead to the first knife you
started with. Slightly tighten all the gib bolts
by following the tightening sequence show in
Figure 63. Repeat this step on the rest of the
knives, then final tighten each gib bolt.

9. If you used the knife setting gauge to set the
knife heights, use the straightedge to adjust
the outfeed table height evenly with the
knives at top dead center (the highest point in
their rotation). If you used the straightedge to
set the knife heights, skip to the next step.
10. Replace the cutterhead guard and the motor
access panel.
