7. Move the dial indicator to the lowest point
of the feed rollers. The reading from the dial
indicator now shows the offset between the
cutterhead
and
adjustments if the offset goes beyond the
tolerance listed below.
Tolerance
Infeed Roller 0.020" - 0.027" below
Chip breaker 0.000" - 0.020" below
Outfeed Roller 0.059" - 0.079" below
8. To adjust the height of the feed rollers,
loosen the jam nuts on both ends of the feed
roller. Rotate the set screws to change the
height of the roller. Continue to calibrate
until the cutterhead-roller offset is uniform
across the entire feed roller.
9. When the correct height is set, hold the set
screws in place and re-tighten the jam nuts.
10. Re-install belt cover when adjustments
complete.

Method 2: Using Feeler Gauge
1. Using hardwood, build a gauge block similar
to this one below. The exact dimension is not
critical. Just make sure the bottom clears the
table roller. The top should be chamfered for
better tool access and visibility.
2. Remove all tools from the planer.
3. Turn on the planer, wait until it reaches full
speed, then shift the feed rate control knob
to 0 FPM (Neutral) position. This allows the
feed rollers to rotate freely.
4. Turn off planer. Disconnect planer from
power source!!
5. Remove the belt cover so you can rotate the
cutterhead with the drivebelt.
