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 MACHINE FROM

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. 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 opposite 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 adjustment

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.

ADJUSTING OUTFEED ROLLER

The outfeed roller continues to feed the stock out of the

machine after the planing operation has been completed

and should be set at .030" below the cutting circle.

To check and adjust the setting of the outfeed roller,

proceed as follows:

1. DISCONNECT MACHINE FROM

POWER SOURCE.

2. Make certain the knives are adjusted properly as

explained in section “CHECKING, ADJUSTING AND

REPLACING KNIVES.”

3. Place gage block (A) Fig. 43, on the table, directly

under cutterhead (B). Using a .030" feeler gage (C) placed

on top of gage block (A), raise the table until the

cutterhead knife just touches feeler gage (A) when the

knife is at its lowest point. NOTE: Do not move the table

any further until the adjustment is complete.
