Anti-Kickback Fingers
The anti-kickback fingers (A, Fig 23) help prevent
kickback of stock. They operate by gravity and it is
necessary to inspect them occasionally to make
sure they are free of gum and pitch, so that they
move independently and operate correctly.
Adjusting Infeed & Outfeed Roller
Spring Tension
To adjust the spring tension of the infeed and
outfeed rollers, turn screws (G & H, Fig. 24) with a
hex wrench. Turn screws on opposite end of
infeed/outfeed rollers in the same manner.

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.
