below the straightedge (a gap exists) or
pushes the straightedge up, proceed to the
next step.
6. Using a 4mm hex wrench, slightly loosen the
four gib screws.
7. Using a 3mm hex wrench, loosen the cam
locking screws to permit adjustment of the
cam (described in the next step).
Important: Always keep the cam locking
screws snug enough so that the cam can't
rotate freely. This is especially important for
when the cam is rotated counterclockwise
since this action will cause the cam locking
screw to loosen further.
8. Using an 8mm hex wrench, adjust the cam.
This is a very sensitive adjustment. Start by
rotating the cam in a clockwise direction just
a few degrees.
9. Next, keep the cutterhead steady by firmly
holding on to the pulley, place a piece of
wood pressed against the knife's edge and
press to properly seat the blade.
10. Check your progress by repeating steps 4
and 5. If the knife becomes more out of
adjustment, turn the cam in the other
direction.
11. The adjustment is almost complete when the
requirements described in Steps 4 and 5 are
met.
12. Next, while pressing the knife firmly against
the cam, snug the two inside gib screws that
hold the gib and knife in place. Verify that
the knife is still in adjustment (steps 4 and
5).
13. Tighten the two outside gib screws, then the
two inside gib screws. Verify that the knife is
still in adjustment (steps 4 and 5).
14. Tighten the gib lock screws.
15. Repeat this entire
remaining two knives.

dangerously sharp. Use extreme caution
when inspecting, removing, or replacing
knives.
To remove/replace a knife (Refer to Figure 8-
13):
1. Remove four gib screws (A) with a 4mm hex
wrench.
2. Remove the gib (B) and knife (C).
If the knife is being reused (knives are
double-edged), clean the knife, gib and
cutterhead of all pitch and debris.
3. Lay the new knife or unused edge of the old
knife back onto the cutterhead (D).
4. Replace the gib (B) and screws (A). Finger
tighten only at this time.
5. Press against the cutting edge of the knife at
the center of the blade with a piece of wood.
DO NOT USE FINGERS! This is to ensure
that the cam is making proper contact with
the knife.
6. Snug the inside two screws, then the outside
two screws.
7. Release the piece of wood pressing against
the knife and tighten the gib screws.
