Height of Infeed Roller, Chipbreaker,
Pressure Bar & Outfeed Roller
The infeed roller, chipbreaker, pressure bar and
outfeed roller are adjusted at the factory. The
infeed roller and the chipbreaker should be set
at 0.004” (0.1mm) below the cutting circle; and
the outfeed roller should be set at 0.02” (0.5mm)
below the cutting circle. See Fig. 25.
If an adjustment to the infeed roller, chipbreaker,
pressure bar or outfeed roller is necessary, use
the following steps as an example of procedure.
To check and adjust the outfeed roller below the
cutting circle, proceed as follows:
1. Disconnect machine from power source.
2. Make sure the knives are adjusted properly
as previously explained under “Checking &
Adjusting of Knives.”
3. Place the gauge block (J, Fig. 26) on the
table directly underneath the cutterhead (D,
Fig. 26). Using a 0.02” (0.5mm) feeler
gauge (K, Fig. 26) placed on top of the
gauge block, raise the working table until
the knife just touches the feeler gauge
when the knife is at its lowest point. Do not
move the working table any further until the
outfeed roller is adjusted.

4. Move the gauge block (J, Fig. 27) under
one end of the outfeed roller (F, Fig. 27).
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 (L, Fig 27)
and turn screw (M, Fig. 27) until the outfeed
roller just touches the gauge block. Then
tighten lock nut (L, Fig. 27).
5. Check and adjust opposite end of the
outfeed roller in the same manner.
