FEED ROLLERS
There are two powered feed rollers on your Oliver 16”
planer. One is located before and the other after the
cutterhead. The feed rollers transmit the work piece
through the machine. The downward pressure on the
work piece is adjustable. If your piece is slipping and
not feeding through the machine, increase the spring
pressure by turning clockwise the pressure nuts with
an allen key as shown in Figure 14. There is a spring
on each end of each feed roll. To ensure great results
make sure both ends are at the same tension. If the
work piece is damaged by the feed roll, decrease the
spring pressure.
