7.5.7 Fan Cut
Use the simple fan cut for making the felling back cut on
trees with a diameter less than the effective cutting length of
the guide bar.
► After creating the felling notch, engage the bumper spikes
of the chain saw directly behind the location of the
intended hinge and 1 to 2 in. (2.5 to 5 cm) higher than the
bottom of the felling notch. Pivot the saw around this point
only as far as the back of the hinge. Do not cut through the
hinge. The bumper spike should roll against the trunk until
the back cut is complete.
7.5.8 Sectioning Method
WARNING
This method is extremely dangerous because it involves the
use of the nose of the guide bar and can result in kickback.
If you are inexperienced with a chain saw, plunge-cutting
should not be attempted. Seek the help of a professional.

of the guide bar.
1
► After creating the felling notch, make the first part of the
felling back cut with the guide bar fanning in toward the
hinge and 1 to 2 in. (2.5 to 5 cm) higher than the bottom of
the felling notch. Pivot the saw around this point only as
far as the back of the hinge. Do not cut through the hinge.
► When repositioning for the next cut, keep the guide bar
fully engaged in the kerf to keep the felling back cut
straight. If the saw begins to pinch, insert a wedge to open
the cut. On the last cut, do not cut the hinge.
► Avoid repositioning the saw more than necessary.
7.5.9 Plunge-cut Method
WARNING
This method is extremely dangerous because it involves the
use of the nose of the guide bar and can result in kickback.
If you are inexperienced with a chain saw, plunge-cutting
should not be attempted. Seek the help of a professional.
