1. Move the fence to the rear and remove the
cutterhead guard.
BE EXTREMELY CAREFUL THAT
YOUR HANDS DO NOT COME IN CONTACT WITH
THE KNIVES. THE KNIVES ARE VERY SHARP.
2. Using wrench (A) Fig. 54, slightly loosen the four
locking screws (B) in each knife slot by turning the
screws (B) clockwise.
3. Loosen screws (B) Fig. 54, further and remove knife
and knife locking bar.
4. Fig. 55, shows the knife (C) and knife locking bar (D)
removed from the cutterhead. Remove the remaining
two knives and locking bars, in the same manner.
5. Using wrench (E) Fig. 55, lower the two knife
adjustment blocks by turning screws (F) counterclockwise

locking bars are thoroughly clean and free of gum and

possible and snug up the screws (B) Fig. 54, by turning
each screw counterclockwise just enough to hold the
knife in position. Replace the remaining two knifes in the
same manner.
