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

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.

Warning!

Felling a tree that has a diameter

greater than the length of the guide bar

requires use of either the sectioning fell-

ing 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 profes-

sionals should attempt these

techniques.
