ADjUSTMENTS
Height of infeed roller, chip breaker and outfeed roller
The infeed roller, chip breaker and outfeed roller are adjusted
at the factory. The height relationship between these items
and the cutterhead is crucial for accurate and safe planing.
The infeed roller, chipbreaker, and outfeed roller should each
be set at 0.02" (0.5mm) below the cutting circle.
See Figure 24.

1. Disconnect machine from power source.
2. Make sure the knives are set properly as previously
explained under "Knife Adjustment."
3. Place the gauge block (F, Figure 25) on the table directly
beneath the cutterhead (D, Figure 25).
4. Using a 0.02" (0.5mm) feeler gauge (G, Figure 25) placed
on top of the gauge block, raise the work table until the
knife just touches the feeler gauge when the knife is at its
lowest point. Do not move the work table any farther until
the outfeed roller is adjusted.
5. Remove the feeler gauge and move the gauge block
(F, Figure 25) under one end of the outfeed roller. The
bottom of the outfeed roller should just touch the top of
the gauge block. If an adjustment to the outfeed roller is
necessary, loosen the lock nut (J, Figure 26) and turn
screw (H, Figure 26) until the outfeed roller just touches
the gauge block. Then tighten lock nut (J, Figure 26).
6. Check and
adjust the
opposite end
of the outfeed
roller in the
same manner.

If any adjustments are necessary for the infeed roller, chip
breaker, or outfeed roller, they should be done carefully.
Use the following steps as an example of procedure.
NOTE: This procedure uses a home-made gauge block and
feeler gauges, which should be sufficient for most planer
operations. If very precise measurements are desired,
however, use a dial indicator device.
Cutterhead
Infeed Roller Height
Use the exact same procedure for checking the infeed roller
as you did for the outfeed roller, Use the .02" (0.5mm) feeler
gauge atop the gauge block. If adjustment is necessary, use
the lock nut and screw on each end of the infeed roller.
Figure 26
Chip breaker Height
The chip breaker breaks off the larger chips before the stock
reaches the cutterhead. Use the gauge block and a
.02" (0.5mm) feeler gauge to check the height of
the chip breaker, following the same procedure as explained
in the previous sections. If adjustment is needed:
1. Remove top cover of planer.
Raise
2. Loosen the lock nuts (A, Figure 27) at both ends of the
table
chip breaker, and turn the set screws (B, Figure 27) to
raise or lower the chip breaker as needed. The set screws
should be turned the same amount.
