Sapwood cuts
Sapwood cuts in long-fibered softwood
help prevent sapwood splintering when
the tree falls. Make cuts at both sides of
the trunk at same height as bottom of
felling notch to a depth of about 1/10 of
trunk diameter. On large diameter trees,
cut to no more than width of guide bar.
Do not make sapwood cuts if wood is
diseased.

Leave approx. 1/10 of the tree

accident.

Leave a broader hinge on rotten
trees.
Shout a second warning immediately
before the tree falls.
