5. Place the black knife gib over the knife with
the angled side up and the angle in the same
direction as the knife edge.
6. Line the outside edges of the knife up with
each other.
7. Replace the (5) 4mm Allen head screws and
tighten from the center out alternating sides

HELICAL CUTTERHEAD ROTATING / CHANGING
CARBIDE CUTTERS
The 8" cutterhead is equipped with 16 index-
able carbide cutters.
Each cutter can be rotated to reveal any one of
its four cutting edges.
Therefore, if one cut-
ting edge becomes
dull or damaged,
simply rotate it 90 to
reveal a fresh cutting
edge (Fig.20).
In addition, each cutter has a reference dot on
one corner. As the cutter is rotated , the refer-
ence dot location can be used as an indicator
of which edges are used and which are new.
When the reference dot revolves back around
to its starting position, the cutter should be
replaced.
TO ROTATE OR CHANGE A CARBIDE CUTTER
1. DISCONNECT THE JOINTER FROM THE POWER
SOURCE.
2. Remove any sawdust from the head of the
carbide cutter Torx screw.
3. Remove the Torx screw and carbide cutter.
4. Clean all dust and dirt off the cutter and the
cutterhead pocket from which the cutter was
removed, and replace the cutter so a fresh,
sharp edge is facing outward.
NOTE: Proper cleaning is critical to achieving
a smooth finish. Dirt or dust trapped between
the cutter and cutterhead will slightly raise the
cutter, and make a noticeable marks on your
workpieces the next time you plane.
5. Lubricate the Torx screw threads with a light
machine oil, wipe the excess oil off the threads,
and torque the Torx screw to 48-50 in/lb.

ADJUSTING FENCE POSITIVE STOPS
The fence on your jointer is equipped with pos-
itive stops at the most used fence positions of
90 degrees and 45 degrees in and out.
To check and adjust the positive stops, proceed
as follows:
WARNING: Make certain that the machine is
disconnected from the power source.
1. Position the fence
at 90 degrees to the
table by loosening
the bevel lock handle
(Fig.21-A) and mov-
ing the fence until 90
degree stop screw (B)
hits the stop (C).
2. Using a square, check to see if the fence is at
90 degrees to the table.
3. If the fence is not
at 90 degrees, loosen
nut (D)and adjust the
stop screw (B) until
the fence is at90 de-
grees to the table.
Retighten nut (D).
4. Tilt the fence in-
ward until it hits the
45 degree in stop nut
(Fig.22-E).
5. Using a combina-
tion square, check
to see if the fence is
indeed tilted in at 45
degrees (Fig.23).
6. If an adjustment is
necessary, tighten or
loosen the stop nut (E) until the fence is at 45
degrees.
7. Tilt the fence outward to 45 degrees. To do
this you will have to flip the 90 degree stop
(Fig.21-C) out of the way so that it faces to-
wards the infeed table.
8. Using a combina-
tion square, check
to see if the fence is
tilted at 45 degrees
(Fig.24).
9. If an adjustment is necessary, loosen or
tighten stop screw (Fig.21-F) until the fence is
at 45 degrees.
