Felling is the process of cutting down a tree. Make
sure your footing is firm. Keep feet apart. Divide
your weight evenly on both feet. Follow directions
below to fell a tree.
Before
Felling
a Tree
1. Before telling, inspect tree. Make sure there
are no dead limbs or branches that may tidl
on you. Study natural lean of tree, location of
larger branches, and wind direction. This will
help you judge which way tree will fall.
2. Clear work area around tree.
3. Plan and clear a retreat path before %lling.
Make retreat path opposite to planned direc-
tion of fall of tree and at 45 ° angle (see Figure
_3).

5. Stay on uphill side when felling tree. Tree

Felling
Procedure
A) Felling
Notch
A properly placed felling notch will determine
direction tree will fall. Place %lling notch on
side of tree in direction you want tree to fall (see
Figure 14). Follow directions below to create a
telling notch.
1. Make lower notch cut as close to ground as
possible. Hold saw so guide bar is horizontal.
Cut 113the diameter of tree trunk (see Figure
14). Note: Always make this horizontal lower
notch cut first. If you make this cut second,
tree can pinch chain or guide bar.
2. Stalt upper notch cut the same distance above
first cut as first cut is deep.
Example: If lowernotch cut is eight inches deep,
start upper notch cut eight inches above it. Cut
downward at 45° angle. The upper notch cut
should meet end of lower notch cut (see Figure
_4).
3. Remove tree trunk wedge created by notching
cuts.

WARNING: Do not cut aHthe way
through tree. Leave about two inches
of tree diameter uncut directly behind
felling
notch
(see Figure
14). This
uncut
portion acts as a hinge. The
hinge helps keep tree from twisting
and falling
in wrong direction.
