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 circle.
To check and adjust the chipbreaker, proceed as
follows:
1. WARNING 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
previously explained under CHECKING,
ADJUSTING AND REPLACING KNIVES.
4. Place the guage block (A) Fig. 29, on the table
directly 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
properly set when the head of corresponding
screw (E) Fig. 32, is two complete turns below
surface of casting (F).
