ADJUSTING PRESSURE BAR

The pressure bar is located directly behind the cutterhead

and rides on the planed surface of the stock, pressing the

stock downward on the table. The pressure bar must be

parallel to the knives and tangent to the table and set

.010” below the cutting circle. To check and adjust the

pressure bar, proceed as follows:

1. DISCONNECT THE MACHINE FROM

THE POWER SOURCE.

2. Make certain the knives are adjusted properly as

explained in the section “CHECKING, ADJUSTING

AND REPLACING KNIVES.”

3. Place gage block (B) Fig. 40, on the table surface and

directly under the cutterhead as shown. Using a .010”

feeler gage (C) Fig. 40, placed on top of the gage

block, raise the table until cutterhead knife (D) Fig. 41

touches the feeler gage when the knife is at its lowest

point. IMPORTANT: DO NOT MOVE THE TABLE

ANY FURTHER UNTIL THE ADJUSTMENT HAS

BEEN COMPLETED.

4. Move gage block (B) Fig. 41, under pressure bar (D) as

shown. The bottom of pressure bar (D) Fig. 41, should

just touch the top of gage block (B). Check the oppo-

site end of the pressure bar in the same manner.

5. If an adjustment to the height of the pressure bar is

necessary, loosen lock nut (E) Fig. 42, and turn adjust-

ment screw (F) until the bottom of pressure bar (D) Fig.

41, just touches top of gage block (B). Repeat the

adjustment at the other end of the pressure bar in the

same manner.

4. Move gage block (B) Fig. 39, directly under chipbreakers

(A) as shown. The bottom of chipbreakers (A) Fig. 39,

should just touch gage block (B).

5. If an adjustment to the chipbreakers is necessary,

loosen two hex nuts (E) Fig. 37, and turn adjustment

screws (F) until chipbreakers (A) touch gage block (B)

at both sides of the table.
