CHECKING, ADJUSTING ANDREPLACING KNIVES

To check, adjust or replace the knives, proceed as

follows:

DISCONNECT MACHINE FROM POWER

SOURCE.

1. Remove four screws (A) Fig. 30 and Fig. 31, and

remove top cover (B).

2. 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.

3. Remove the three screws (E) Fig. 34, and remove the

chip deflector (F).

4. 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.
