6. Move the gauge to the extreme right end of
the infeed roller and check. Make similar
adjustments if needed.
7. Tighten hex nuts (A, Figure 14) when
finished.
IMPORTANT: The setting on both ends of the
infeed roller must be the same to avoid skewing
of the material as it is fed through the machine.
Chipbreaker
The chipbreaker is a sectionalized type made of
spring-loaded sections mounted on a bar, which
complements the sectional infeed roller. The
functions of the chipbreaker are to break chips
into small pieces, help avoid splintering of the
wood, help avoid board bounce on thinner
boards, to direct the flow of chips out of the
machine, and to permit multiple board surfacing.
The chipbreaker has been factory set at 1/32”
(0.8mm) below the cutting arc of the knives, and
has been spring-tensioned properly.
A chipbreaker set too low or
with excessive tension may prevent stock
from feeding into the machine.
Pressure Bar
Most planing problems can be traced to
improper setting of the pressure bar. Its function
is to hold down the material after it passes under
the cutterhead and throughout the remainder of
the cut. Its basic setting is to be in line with the
arc of the cutterhead knives.
If the pressure bar is too high, a shallow "clip"
will occur at each end of the board. If it is too
low, stock will not feed through.
Use a gauge to set the full length of the
pressure bar to be .000-.001" (.02mm) below
the arc of the cutterhead.
Figure 15 shows the height adjustment screw
(C) and the spring tension adjustment screw (D)
for the pressure bar. Loosen the hex nut and
rotate the screw as needed. Make sure the
setting on both ends of the pressure bar is the
same. Tighten the hex nuts when adjustment is
complete.
This initial setup is a starting point and final
adjustment may have to be made during a test
cut.
