Wilton 15S, 15HH manual Anti-Kickback Fingers, Infeed and Outfeed Roller Spring Tension

Anti-Kickback Fingers

The anti-kickback fingers (A, Figure 23) are an important safety feature, as they help prevent kickback of stock. They operate by gravity and should be inspected frequently to make sure they are free of gum and pitch, so that they move independently and operate correctly.

Infeed and Outfeed Roller Spring Tension

The infeed roller (B, Figure 23) and outfeed roller (E, Figure 23) are those parts of your planer that feed the stock while it is being planed. The infeed roller and the outfeed roller are under spring tension and this tension must be sufficient to feed the stock uniformly through the planer without slipping but should not be so tight that it causes damage to the board. The tension should be equal at both ends of each roller.

To adjust the spring tension of the infeed and outfeed rollers, turn screws (Figure 24) with a hex wrench. Turn screws on both ends of infeed/outfeed rollers in the same manner.

Height of Infeed Roller, Chipbreaker and Outfeed Roller

The infeed roller, chipbreaker 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 25.

If any adjustments are necessary for the infeed roller, chipbreaker, 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 extra precise measurements are desired, however, use a dial indicator device. A bed and feed roller gauge with dial indicator (stock # 2230002) is available as an accessory for this machine, and may be purchased through our customer service department.
