cutterhead knives on the planer, proceed as
follows:
E
B
A. WARNING DISCONNECT MACHINE FROM
POWER SOURCE
B. Remove the top cover of the planer exposing the
cutterhead.
C. Check all four knives for proper setting using the
knife guage (A), as shown in Fig. 20. When the gu
age
(A) is placed on the cutterhead and the bottom of the
two roll pins, one of which is shown at (B), are against
the edge of the slot (C) opposite the knife, the knife
should just contact the bottom of the guage (D).
D. If any of the knives require an adjustment, slightly
loosen the knife locking bar of ea
ch of the four knives
by turning the knife locking screws (E) Fig. 20, into the
locking bar just enough to relieve stress in the
cutterhead but not disturb the setting of the four
knives.
E. To adjust the knife that must be reset, loosen all of
that knife's locking
screws (E) Fig. 20, 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 the guage (D). Then
snug up the knife locking bar by lightly backing out the
locking screws (E) against the knife slot.
IMPORTANT: AT THIS TIME, ONLY TIGHTEN THE
KNIFE INTO THE SLOT ENOUGH TO HOLD IT IN
POSITION. F. If additional knives must be reset,
repeat STEP C.
G. After all four knives are set with the screws just
snu
g, back out and tighte
n the locking screws, five of
which are shown at (E) Fig. 20, against the slot. Start
with the end screws first and proceed on alternate
sides toward the center screws until the knife is
securely held in the cutterhead. Tighten the remaining
three knives in the same manner.
