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.
The plunge cut is made with the guide
bar nose. 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 shown in
illustration.
Warning!
There is an extreme danger of kickback
at this point. Extra caution must be taken
to maintain control of the saw. To make
the felling cut, follow the sectioning
method described previously.
If you are inexperienced with a chainsaw,
plunge-cutting should not be attempted.
Seek the help of a professional.
Limbing
Limbing is removing the branches from
a fallen tree.
Warning!
There is an extreme danger of kickback
during the limbing operation. Do not work
with the nose of the bar. Be extremely
cautious and avoid contacting the log or
other limbs with the nose of the guide bar
Do not stand on a log while limbing it —
you may slip or the log may roll.
Start limbing by leaving the lower limbs to
support the log off the ground. When
underbucking freely hanging limbs,
a pinch may result or the limb may fall
causing loss of control. If a pinch occurs,
stop the engine and remove the saw,
by lifting the limb.
