lightly backing out the six locking screws (F,
Fig. 19) against the slot. NOTE: At this time,
only tighten the knife in the slot just enough to
hold knife in position.

7. After all four knives are set with screws just
snug, back out and tighten the six locking
screws (F, Fig. 19 & 20), against the slot
starting with the end screws first, then the
center screws, until the knife is securely held

Replacing & Resetting Knives
If the knives are removed for sharpening, care
must be exercise in replacing and resetting them.
Proceed as follows:
1. Disconnect machine from power source.
2. Remove six screws and upper cover (see
Fig. 18).
3. To remove knife, loosen the gib (E, Fig. 19) by
turning the six locking screws (F, Fig. 19) into
the gib. Remove gib (E, Fig. 19), knife (G, Fig.
16) and springs (H, Fig. 19). NOTE: The inner
two springs may pop out when the knife and
gib are removed.
4. Remove the remaining three knives in the
same manner.
5. Thoroughly clean the knife slots, gibs, springs
and locking screws. Check the locking screws;
if the threads appear worn or stripped or if the
heads are becoming rounded, replace them.
6. Inspect the cutting edge of the knives for nicks
or wire edge. Hone the knives slightly using a
stone, or if the knives are to be sharpened,
maintain a cutting angle of 35 degrees.
7. Insert springs, knives and gib into slot of
cutterhead. Back out locking screws just
enough to hold the knife in the cutterhead.
8. Place knife gauge (C, Fig. 19) over knife.
9. While holding down on the knife gauge,
loosen all six locking screws (F) by turning
them into the gib (E) until cutting edge of knife
comes into contact with the protrusion (D) of
the gauge. Snug up the gib by slightly backing
out the six locking screws against the slot.
Note: At this time, only tighten the knife into the
slot just enough to hold the knife in position.
