4.If an adjustment to one or both knives is necessary, slightly loosen the seven locking screws, six of which are shown at (C) Fig. 21, by turning the screws CLOCKWISE into the knife locking bar just enough to relieve stress in the cutterhead and not disturb the knife setting.
5.With setting gage (B) Fig. 20, in place, apply pressure to the knife being reset. Turn the seven knife locking screws
(C) Fig. 21, CLOCKWISE until the knife locking bar becomes loose. Lift springs will automatically raise the knife until it comes in contact with gage (B) Fig. 20. Snug the knife locking bar by lightly turning the seven locking screws (C) Fig.
21, COUNTERCLOCKWISE. IMPORTANT: AT THIS TIME, ONLY TIGHTEN THE KNIFE LOCKING BAR JUST ENOUGH TO HOLD THE KNIFE IN POSITION INSIDE THE CUTTERHEAD SLOT.
6.If the other knife needs adjustment, repeat STEP 5.
7.After both knives are positioned in the cutterhead, turn each of the seven screws, six of which are shown at (C) Fig. 21, COUNTERCLOCKWISE until the knife is secure in the cutterhead. NOTE: When tightening knife locking
screws, tighten the end screws first, then inward toward the center of the cutterhead. MAKE CERTAIN
THAT THE KNIFE LOCKING BAR (D) FIG. 22, IS FLUSH AGAINST THE KNIVES (E) BEFORE SECURING THE KNIFE LOCKING SCREWS (C).
8.Replace chip deflector (A) Fig. 19. MAKE SURE THAT THE CHIP DEFLECTOR IS PROPERLY
SECURED WITH THE WING NUTS BEFORE OPERATING THE TOOL.

IF THE KNIVES ARE TO BE REMOVED FOR SHARPENING OR REPLACEMENT, EXTREME CARE SHOULD BE TAKEN AS THE KNIVES ARE VERY SHARP. TO REPLACE OR RESET THE KNIVES, PROCEED AS FOLLOWS:
DISCONNECT MACHINE FROM POWER SOURCE.
1.Lower the head assembly by turning handle (B) Fig. 15.
2Remove chip deflector (A) Fig. 19.
3.Carefully place knife setting gage (B) Fig. 20, on the cutterhead so the rounded sections are directly over the knife as shown.
4.Loosen the knife locking bar by turning the seven knife locking screws, six of which are shown at (C) Fig. 21, CLOCKWISE and carefully remove knife locking bar (D) Fig. 22, knife (E), and springs (not shown) which are located under the knife.
5.Remove the remaining knife in the same manner.
6.Thoroughly clean the knife slots, knife locking bars and screws (with a soft cloth moistened with kerosene). Check the screws. If the threads appear worn or stripped or if the heads are damaged, replace them.
7.Carefully replace the springs (not shown), knives (E) Fig. 22, and knife locking bars (D), into both slots of cutterhead (F).
WHEN REPLACING KNIFE LOCKING BARS (D) AGAINST KNIVES (E), AS SHOWN IN THE CROSS- SECTIONAL ILLUSTRATION Fig. 22, MAKE CERTAIN THE BARS ARE INSTALLED AS SHOWN, WITH SCREWS (C), POSITIONED AT THE TOP OF KNIFE LOCKING BARS (D), AND ANGLED DOWNWARD HOLDING THE KNIVES (E) PROPERLY INSIDE THE CUTTERHEAD SLOTS. TURN KNIFE LOCKING SCREWS, ONE OF WHICH IS SHOWN AT (C), COUNTERCLOCKWISE JUST ENOUGH TO HOLD BOTH KNIVES (E) IN THE CUTTERHEAD (F).
8.Adjust both knives as explained in section “ADJUSTING KNIVES”, STEPS 5, 6 and 7.
