6. Raise the headstock, place the gauge block
below the cutterhead. For checking the
infeed roller’s offset, put the 0.020” feeler
gauge on top of the gauge block.
7. Lower the cutterhead until the lowest point
of the cutterhead barely touches the feeler
gauge.
8. Remove the feeler gauge and move the
gauge block under the infeed roller. The
gauge block should fit right under the infeed
roller if the height setting is perfect. You may
need to rotate the infeed roller to find the
lowest spot. Made adjustments according to
the specifications as needed:
Tolerance
Infeed Roller 0.020” - 0.027” below
Chip breaker 0.000” - 0.020” below
Outfeed Roller 0.024” - 0.031” below
9. 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.
10. When the correct height is set, hold the set
screws in place and re-tighten the jam nuts.
11. Repeat STEP 7-13 for the outfeed roller, and
use a 0.030” feeler gauge instead.
12. Re-install belt cover when adjustments
complete.
Adjust Feed Roller Tension
If your workpiece is slipping and not feeding
through the machine, increase the feed roller
pressure by turning the pressure bolts clockwise
with a hex wrench.
There is a pressure adjustment bolt on each end
of the feed rollers. Make sure the adjustments
are made on BOTH ends of the feed roller, so
even pressure is applied across the entire feed
roller.
If the workpiece is damaged by the feed roller,
reduce pressure.
