4.2 Feed Speed Adjustment
The feed speed can be adjusted to suit the material being chipped. Turn dial to align
number with pip. Set feed speed so that the No-Stress operates as little as possible,
this will give the highest throughput. When feeding Leylandii or leafy material, set
feed roller speed to 4.5.
