CHECkINg, RESTTINg AND REPLACINg kNIVES
1. Remove the locking screw (E) Fig. 4, and raise top cover (A) Fig. 30.
2. Carefully place the knife setting gauge (C) Figs. 31 and 32, so that the gauge is positioned on the radiused section of
the cutterhead (B). When set correctly, the knife (D) Figs. 31 and 32, should contact the bottom of the inset section
(E) Fig. 32 of the knife setting gauge (C) set at .070". Check the remaining knives in the same manner.
3. If an adjustment to any of the knives is necessary, slightly loosen the ten locking screws, one of which is shown at
(F) Fig 31 and Fig. 32 enough to relieve stress in cutterhead (B) and not disturb the knife setting.
4. With knife setting gauge (C) Figs. 31 and 32 still in place on the cutterhead, adjust the knife by turning the ten knife
locking screws CLOCkWISE until the knife locking bar (G) becomes loose. Lifter springs (not shown) located under
the knife will automatically raise the knife until it comes in contact with the gauge (C). Snug up the knife locking bar
(G) Fig. 31 and Fig. 32, by turning the ten screws (F) COUNTER-CLOCkWISE.
IMPORTANT: Loosely tighten the screws enough to hold the knive in position for further adjustment.
5. If other knives need adjustment, repeat STEP 4.
6. After all the knives are positioned in the cutterhead with the knife locking screws snug, turn each of the ten locking
screws(F) Fig.34, COUNTER-CLOCkWISE UNTIL THE kNIVES ARE SECURE IN THE CUTTERHEAD.
NOTE: When tightening the knife locking screws (F), tighten the end screws first, then proceed inward toward the center of
the cutterhead.
Wear gloves when you remove the knives for sharpening or replacement. These knives are very
sharp.

7. Carefully position the knife setting gauge (C) Fig. 31 on
the radiused section of the cutterhead (B) Fig. 32.
8. Loosen the knife-locking bar (G) Figs. 31 and 32 by
turning the ten knife-locking screws, one of which is
shown at (F) CLOCkWISE and carefully remove the
locking bar (G), knife (D), and springs (not shown and
located under the knife) from the cutterhead. Remove
the remaining knives in the same manner.
9. Thoroughly clean the knife slots, locking bars, and
locking screws. Check the screws. If the threads
appear worn or stripped, or if the heads are damaged,
replace them.
10. Carefully replace the springs (not shown), knives
(D) Fig. 31 and 32, and locking bars (G) into the three
slots in the cutterhead (B).
HOW TO CONSTRUCT THE gAUgE BLOCk
You will need a gauge block to check and adjust the
height of the chipbreaker, pressure bar, infeed and outfeed
rollers, and to adjust the cutter-head parallel to the table,
The gauge block can be constructed out of hardwood by
following the dimensions shown in Fig. 33.
