◾
Before felling is started, consider the natural lean of the tree, the location of larger
branches and the wind direction to judge which way the tree will fall.
◾
Remove dirt, stones, loose bark, nails, staples, and wire from the tree where
felling cuts are to be made.
Notching undercut
Make the notch 1/3 the diameter of the tree, perpendicular to the direction of fall, as
illustrated in Fig. 18. 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 (see Fig. 23).
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.
