Felling Cut for Small Diameter Trees:
Simple Fan Cut
Engage the bumper spikes of the chain
saw directly behind the location of the
intended hinge and pivot the saw around
this point only as far as the hinge. The
bumper spike rolls against the trunk.
Felling Cut for Large Diameter Trees
WARNING
Felling a tree that has a diameter greater
than the length of the guide bar requires
use of either the sectioning felling cut or
plunge-cut method. These methods are
extremely dangerous because they
involve the use of the nose of the guide
bar and can result in kickback. Only
properly trained professionals should
attempt these techniques.
Sectioning Method
For the sectioning method make the first
part of the felling cut with the guide bar
fanning in toward the hinge. Then, using
the bumper spike as a pivot, reposition
the saw for the next cut.
Avoid repositioning the saw more than
necessary. When repositioning for the
next cut, keep the guide bar fully
engaged in the kerf to keep the felling
cut straight. If the saw begins to pinch,
insert a wedge to open the cut. On the
last cut, do not cut the hinge.
Plunge-cut Method
Timber having a diameter more than
twice the length of the guide bar requires
the use of the plunge-cut method before
making the felling cut.
First, cut a large, wide felling notch.
Make a plunge cut in the center of the
notch.
