1. Determine the direction that the tree will fall.
Take the following variables into consideration:
•
Wind direction
•
Heavier limbs on 1 side of the tree
•
Natural tilt of the tree (if any)
2. Determine a clear, safe retreat path away from
the danger area; refer to
Figure 17
1. Retreat path (at a 45°
angle opposite from the
planned direction of fall)
2. Planned direction of fall
3. Grip the chain saw as shown in
4. Make the first cut a third of the way through the
tree diameter on the side where you want the
tree to fall (Figure

Note:
Making this cut prevents the chain saw
from being pinched while making the next cut.

5. Make a second cut to form a notch, starting the
cut at least 5 cm (2 inches) above and away
from the first cut
Important:
second cut meet at the same point, forming
a clean notch.
6. Make the back cut from the opposite side of the
notch and about 5 cm (2 inches) higher than the
bottom of the notch as shown in
Important:

or twisting as it falls.
Note:
As the back cut nears the hinge

saw, shut it off, put it down, and retreat along the
path you determined in step 2.
