The engine management unit controls the feed rate of the material going into the shredding chamber.
If the engine speed is below the predetermined level, the engine management unit will not allow the feed
roller to work in the forward “infeed” direction, until the drum speed rises above the predetermined level.
At this point, the feed roller will start turning without warning. The reverse function will work at any
engine speed.
