ADJUSTING THE CHIPBREAKER

The chipbreaker is located on the top of the planer and extends down around the front of the cutterhead. The chip-breaker segments raise as stock is fed through and "break or curl" the chips the same as the plane iron cap on a hand plane. The bottom of the chipbreaker must be parallel to the knives and set .040" below the cutting cir- cle. To check and adjust the chipbreaker, proceed as fol- lows:

1. DISCONNECT MACHINE FROM POWER SOURCE

2.Remove the four screws that attach the top cover to the planer and carefully remove the top cover.

3 Make certain the knives are adjusted properly as pre- viously explained under CHECKING, ADJUSTING AND REPLACING KNIVES.

4.Place the guage block (A) Fig. 29, on the table direct- ly underneath the cutterhead as shown. To adjust the chipbreaker, place a .040" feeler gauge (B) Fig. 29, on top of the guage block and raise the table until the knife

(C) just touches the feeler guage when the knife is at its lowest point.

5.Move the guage block (A) Fig. 30, underneath each chipbreaker segment (B) as shown. The bottom of each chipbreaker segment should just touch the top of the guage block.

6.If an adjustment to any of the chipbreaker segments is necessary, loosen the corresponding lock nut, such as

(C) Fig. 31, and turn adjusting screw (D) in or out as required. Then tighten lock nut (C).

7.Spring tension on the chipbreaker segments is prop- erly set when the head of corresponding screw (E) Fig. 32, is two complete turns below surface of casting (F).
