► After creating a large felling notch, begin the plunge cut by
applying the lower portion of the guide bar nose to the tree
at an angle. Cut until the depth of the kerf is about the
same as the width of the guide bar. Next, align the saw in
the direction in which the recess is to be cut.
► With the saw at full throttle, insert the guide bar in the
trunk.
► Enlarge the plunge cut as illustrated in the illustration
above.
► Follow the sectioning method described previously to
