Small diameter trees: Simple fan cut
N Apply the spiked bumper behind the
hinge – pivot the saw around this
point - only as far as the hinge. The
spiked bumper rolls against the
trunk.
Large diameter trees: Sectioning
method
If the diameter of the tree is greater than
the length of the guide bar, use the
sectioning method.
1. First cut
Nose of guide bar should enter
wood just behind the hinge – hold
the saw horizontally and swing it as
far as possible, using the bumper
spike as a pivot – avoid
repositioning the saw more than
necessary.
2. When repositioning the saw for the
next cut, keep the guide bar fully
engaged in the kerf to keep the
felling cut straight – apply the spiked
bumper again, and so on.
3. Insert a wedge (3) in the cut.
4. Last cut: Apply the spiked bumper
as for the simple fan cut – do not cut
through the hinge.
