CAUTION: Limbing may only be performed by
trained persons. A hazard is presented by the risk

not cut with the tip of the bar, as this presents a risk of kickback.
Pay particular attention to branches under tension. Do
not cut unsupported branches from below.
Do not stand on the felled trunk when limbing.
Burrowing and parallel-to-grain cuts
CAUTION:
Burrowing and parallel-to-grain cuts
may only be carried out by persons with special train-

Perform parallel-to-grain cuts at as shallow an angle as
cut as the spike bumper cannot be used.
