CHECKING, ADJUSTING AND
REPLACING KNIVES

To check, adjust or replace the knives, proceed as
follows:

DISCONNECT MACHINE FROM POWER

SOURCE.

Remove four screws (A) Fig. 30 and Fig. 31, and
remove top cover (B).

Loosen two screws (C) Fig. 32, and pivot motor
assembly (D) to the front. NOTE: Belt tension is not
disturbed when pivoting the motor forward.

THE CUTTER-HEAD AND KNIVES ARE

NOW EXPOSED AND CARE SHOULD BE TAKEN AS
THE KNIVES ARE VERY SHARP.

Remove the three screws (E) Fig. 34, and remove the
chip deflector (F).

To check and adjust the knives, proceed as follows:

A. Carefully place the knife setting gage (G) Fig. 35,

on the cutterhead as shown.

B. When the knives are adjusted correctly, the knife

(H) Fig. 36, should just contact the bottom of the
gage (J), at each end of the gage. Check the
remaining two knives in the same manner.

C. To adjust the knife that must be reset, loosen all

five locking screws, two of which are shown at
(K) Fig. 37, by turning them clockwise into the
lock bar. Then using the wrench supplied, turn
allen screw (L) Fig. 37, counterclockwise to
lower or clockwise to raise the knife on each end
of the cutterhead until the cutting edge of knife
(H) Fig. 36, just touches the bottom of the gage
(J). Then snug up the knife locking bar by lightly
backing out the five locking screws, two of
which are shown at (K) Fig. 37, 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, back out and

tighten the five locking screws, two of which are
shown at (K) Fig. 37, 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.
