This chipper/shredder is designed for dry material only. Never place green material or bamboo into chipper.
maximum branch thickness that can be chipped is dependent on the type
of wood and the quality of the goods being cut, but never thicker than
1-1/2" in diameter. For hard wood (e.g. oak/beech branches), the maximum
branch thickness that can be chipped is less than for soft wood (e.g.
pine/spruce wood). For dry or knotted wood, the cutting thickness may
also be less.
