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.
