1. For your first cut, undercut the branch 1/3 through the diameter of the
branch (Figure 16).
2. For your second cut, overcut the first cut to drop the branch off.
3. Now make your finishing cut from the topside of the branch smoothly and
neatly against the main member so the bark will grow back to seal the
wound.
Felling Trees
The Chainsaw operator should keep themselves on the uphill side of the terrain
as the tree is likely to roll or slide downhill after it is felled. An escape path
should be planned and cleared as necessary before cuts are started. The escape
path should extend back and diagonally to the rear of the expected line of fall
(Figure 17). Before felling is started, consider the natural lean of the tree and the
location of larger branches.
CUTTING THE NOTCH
1. Make the first horizontal cut of the Notch 1/3 through the diameter of the
tree, perpendicular to the direction of where you want the tree to fall (Figure
18). Always Make the lower horizontal notching cut first, this will help to
avoid pinching either the Saw Chain or the Bar when the second notch cut
is being made.
2. Make the second notch cut at 45˚ angle to the horizontal cut until the two
cuts intersect.
FELLING BACK CUT
Note: The hinge wood mentioned in the next step keeps the tree from twisting and
falling in the wrong direction. Do not cut through the hinge.
1. Make a felling back cut at least 2 inches higher than and parallel to the
horizontal notch cut with enough wood is left to act as a hinge.
2. As the felling back cut gets close to the hinge, the tree should begin to fall.
3. 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.
4. When the tree begins to fall, remove the Chain Saw from the cut, stop the
motor, put the Chainsaw down, and move away from the tree using the
planned retreat path. Be alert for overhead limbs falling and watch your
footing.
e
Trees should not be felled in a manner that would endanger any person,
strike any Utility Line or cause any property damage.
Trees felled on a Utility
Line could kill the operator.
If the tree does make contact with any Utility
Line, the Utility Company must be notified immediately.
