Feed Roller Height
Figure 18. Chip breaker height adjustment.
6. If an adjustment is necessary, loosen the
locknuts and turn the setscrews. See Figure
18. Stop turning when the bottom of the chip
breaker just touches the gauge block.
7. Re-tighten both locknuts
8. Replace the exhaust hood.
The infeed and outfeed rollers propel the lumber
through the planer. The rollers also press the
lumber flat against the planer table.
Set the infeed and outfeed rollers 0.040" below
the knife edge at bottom dead center.
TO CHECK ROLLER HEIGHT:
1. Disconnect the machine from the power
source.
2. Lower the table so the gauge block will fit
under one side of the infeed roller.
3. Raise the table until the gauge block barely
touches the infeed roller. See Figure 19. Do
not change position of the table.
4. Slide the gauge block over so it is under the
edge of one of the knives. Turn the cutter-
head until one of the knives is at bottom
dead center over the gauge block.
5. Measure the clearance between the top of
the gauge block and the edge of the knife
with a feeler gauge. Note the measurement
indicated on the feeler gauge.
