REMOVING, REPLACING AND RESETTING KNIVES
If the knives are removed from the cutterhead for replacement or
regrinding, care must be used in removing, replacing and resetting them
as follows:
1.
DISCONNECT THE MACHINE FROM ITS POWER SOURCE.
2. Move the fence to the rear and remove the cutterhead guard.
WARNING: BE EXTREMELY CAREFUL THAT YOUR HANDS DO
NOT COME IN CONTACT WITH THE KNIVES.
3. Using wrench (A) Fig. 48, slightly loosen the four locking screws (B) in
each knife slot by turning the screws (B) clockwise. This relieves stress
in the cutterhead.
4. Loosen screws (B) Fig. 48, further and remove knife and knife locking
bar.
5. Fig. 49 illustrates the knife (C) and knife locking bar (D) removed from
the cutterhead. Remove the remaining two knives and locking bars, in
the same manner.
6. Using hex. key (E) Fig. 49, lower the two knife adjustment blocks by
turning screws (F) counterclockwise in all three slots of the cutterhead.
7. Before replacing knives make certain the knife locking bars are
thoroughly clean and free of gum and pitch.
8. Replace the knife locking bars (D) Fig. 49 and knives (C) into each slot
in the cutterhead.
WARNING: CARE MUST BE TAKEN WHEN
INSERTING THE KNIVES AS THE CUTTING EDGES ARE VERY
SHARP.
Push the knife down as far as possible and snug up the screws
(B) Fig. 48, by turning each screw counterclockwise just enough to
hold the knife in position. Replace the remaining two knives in the
same manner.
NOTE: KNIVES MUST BE INSTALLED CORRECTLY
AS SHOWN IN FIG. 50.
9. The knives are adjusted correctly when the cutting edge of the knife
extends out 0.060˝ from the cutterhead diameter.
10. Carefully rotate the cutterhead (G) Fig. 51, until the round portion of
the cutterhead is on top as shown.
11. Place a 0.060˝ feeler gage (H) Fig. 51, on the cutterhead and using a
straight edge (J) on the rear table adjust the height of the rear table
until it is 0.060˝ above the cutting head diameter, as shown.
12. Lock the rear table in position and remove the feeler gage.
13. Lower the infeed table and place a straight edge (J) Fig. 52, on the
outfeed table extending over the cutterhead as shown.
14. Rotate the cutterhead by hand until the knife is at its highest point at
each end of the cutterhead. To raise the knife, use hex. key (E) Fig. 52,
and turn raising screw clockwise until the knife just touches the
straight edge (J) on each end and center of the cutterhead when the
knife is at its highest point. When you are certain the knife is
adjusted properly, tighten the four locking screws (B) by turning
them counterclockwise.
15) Adjust the remaining two knives in the same manner.
WARNING!
MAKE CERTAIN THAT ALL KNIVES ARE SECURELY FASTENED
IN CUTTERHEAD BEFORE TURNING ON POWER.
16. Replace cutterhead guard and reposition guide.
