B.
If any of the knives require an adjustment,
slightly loosen the knife locking bar of each of the
three knives by turning the locking screws (D) Fig, 49,
into the locking bar just enough to relieve stress in the
cutterhead but not disturb the setting of the three
knives.
C.
To adjust the knife that must be reset, loosen all
four locking screws (D) Fig. 49, by turning them into
the locking bar. As the knife locking bar becomes
loose, lifter springs under the knife will raise the knife
until it contacts the bottom of both set screws (B) of
the gage. Then snug up the knife locking bar by lightly
backing
out the four locking screws (D) against the
knife slot. IMPORTANT:
AT THIS TIME, ONLY
TIGHTEN THE KNIFE INTO THE SLOT ENOUGH
TO HOLD IT IN POSITION.
D.
If additional knives must be reset, repeat Step C.
E.
After all three knives are set with screws just
snug, back out and tighten the four locking screws (D)
Fig. 49, against the slot, starting with the end screws
first, then the center screws until the knife is securely
held in the cutterhead. Tighten the remaining two
knives in the same manner.
5.
If the knives are removed for sharpening, care must be
exercised in replacing and resetting them, as follows:
A.
To remove each knife, loosen the knife locking
bar, by turning the four locking screws (D) Fig. 49,
into the knife locking bar and remove the locking bar,
knife and springs located under the knife.
B.
Remove the remaining two knives in the same
manner,
C.
Thoroughly clean the knife slots, knife bars,
springs and screws. Check the screws. If the threads
appear worn or stripped or if the heads are becoming
rounded replace them.
D.
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.
E.
Insert springs, knives and knife locking bars into
all three slots in the cutterhead. Back out locking
screws (D) Fig. 49, just enough to hold all three knives
in the cutterhead.
F.
Adjust all three knives as explained in Step 4,
above.
