Notching undercut
Make the notch 1/3 the diameter of the
tree, perpendicular to the direction of fall,
as illustrated in Fig. 22. Make the lower
horizontal notching cut first. This will help
to avoid pinching of either the saw chain
or the guide bar when the second notch is
being made.
Felling Back Cut
1. Make the felling back cut at least 2 inches (50.8 mm) higher than the horizontal
notching cut (Fig. 22). Keep the felling back cut parallel to the horizontal notching
cut. Make the felling back cut so that enough wood is left to act as a hinge. The
hinge wood keeps the tree from twisting and falling in the wrong direction. Do not
cut through the hinge.
2. As the felling cut gets close to the hinge, the tree should begin to fall. If there is
any chance that the tree may not fall in the desired direction or it may rock back
and bind the saw chain, stop cutting before the felling back cut is complete and
use wedges of wood, plastic or aluminum to open the cut and drop the tree along
the desired line of fall.
3. When the tree begins to fall, remove the chain saw from the cut, stop the motor,
put the chain saw down, then use the retreat path planned. Be alert for overhead
limbs falling and watch your footing.
LIMBING
Limbing is removing branches from a
fallen tree. When limbing, leave larger
limbs to support the log off the ground.
Remove the small limbs in one cut as
illustrated in Fig. 23. Branches under
tension should be cut from the bottom up
to avoid binding the chain saw.
WARNING:
danger of kickback during the limbing operation. Be extremely cautious and avoid
contacting the log or other limbs with the tip of the guide bar.
