below to fell a tree.
Before
Felling a Tree
1. Before felling, inspect tree. Make sure there are
no dead limbs or branches that may fall 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 retre* path before telling. Make
retreat path opposite to planned direction of fail
of tree and at 45 ° angle (see Figure 9).
4.
5.
Remove dirt, stones, loose bark, nails, staples, and
wire fl'om tree where you will make telling cuts.
Stay on uphill side when telling tree. Tree could
roll or slide downhill after falling.

Retreat Path
Figure 9 Retreat Path From Tree
Felling Procedure
A) Felling Notch
A properly placed felling notch will determine direc-
tion tree will fall. Place telling notch on side of tree in
direction you want tree to fall (see Figure 10. 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 113 the diameter
of tree trunk (see Figure
10). Note: Always make this horizontal
lower
notch cut first. If you make this cut second, tree
can pinch chain or guide bar.
2.
Start upper notch cut the same distance
above
first cut as first cut is deep.
Example:
If lower notch 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 10).
3.
Remove tree trunk wedge created by notching cuts.
B) Felling Cut
1. Make felling cut two inches higher than lower
notch cut and on opposite side of tree (see Figure
10). Keep telling cut parallel to lower notch cut.
2.
Cut towards
notch.
3.
As Mling cut nem_ hinge, tree should begin to f_dl.
Note:
If needed, drive wedges into telling cut to
control direction of fall. If tree settles back and
pinches chain, drive wedges into telling cut to re-
move saw. Only use wedges made of wood, plastic,
or aluminum. Never use wedge made of steel. This
couM cause kickback and damage to chain.
4.
When tree begins to fall quickly
• remove saw from telling cut
• release trigger to turn saw off
• put saw down
• exit area using retreat path
