CHAIN SAW INFORMATION
Felling Procedure
A) Felling Notch
A properly placed felling notch will determine
direction tree will fall. Place felling notch on
side of tree in direction you want tree to fall (see
Figure 12). Follow directions below to create a
felling notch.
1.
Make lower notch cut as close to ground as
possible. Hold saw so guide bar is horizontal.
Cut 1/3 the diameter of tree trunk (see Figure
12). 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° ang
le. The
upper
notch cut should meet end of lower notch cut
(see Figure 12).
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 12). Keep felling cut parallel to lower
notch cut.
2.
Cut towards notch.
WARNING: Do not cut all the way
through tree. Leave about two inches
of tree diameter uncut directly behind
felling notch (see Figure 12). This uncut
portion acts as a hinge. The hinge helps
keep tree from twisting and falling in
wrong direction.
WARNING: Be alert for falling over-
head limbs. Watch your footing while
exiting area.
3. As felling cut nears hinge, tree should begin to
f
all. Note: If needed, drive wedges into felling
cut to control direction of fall. If tree settles back
and pinches chain, drive wedges into felling cut
to remove saw. Only use wedges made of wood,
plastic, or aluminum. Never use wedge made of
steel. This could cause kickback and damage to
chain.
4.
When tree begins to fall, quickly
• remove saw from felling cut
• release trigger to turn saw off
• put saw down
• exit area using retreat path
