ANTI-KICKBACK FINGERS

Anti-kickback fingers help prevent stock from being thrown from the machine. These fingers operate by gravity and should be inspected before each day's use for pitch or gum buildup. The fingers must operate freely and move independently for correct operation.

INFEED ROLL

The function of the infeed roll is to feed the material into the machine. It is a corrugated, sectional roll with approximately 5/16" independent movement of each section to accomodate multiple board surfacing.

To provide proper drive, it should be set so that the bottom of its arc is 1/16" (1.6mm) below the arc of the cutterhead knives. The infeed roll is 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 boards. The tension should be equal at both ends of each roll.
