angle to a depth of about 1/5 to 1/4
of the trunk diameter.
: Make second cut horizontal.
: Remove resulting 45-degree piece.

Making sapwood cuts
: For medium sized or larger trees
make cuts at both sides of the trunk,
at same height as subsequent
felling cut.
: Cut to no more than width of guide
bar.
This is especially important in softwood
in summer - it helps prevent sapwood
splintering when the tree falls.
