Making a felling notch
With the help of the gunning sight on the
shroud and fan housing of the chain
saw, it is possible to check the direction
of fall when cutting the felling notch.
When making the felling notch, orient
the chain saw so that the gunning sight
points precisely in the direction in which
you want the tree to fall.
Several possibilities are permissible
when it comes to the sequence of
horizontal and diagonal cuts – observe
national regulations with regard to felling
technique.
The felling notch (C) determines the
direction of fall.
STIHL recommends the following
procedure:
N
Make a horizontal cut – in doing so,
check the direction of fall with the
gunning sight
N
Start a diagonal cut at an
approx. 45° angle
N
Check the felling notch – then
correct the felling notch, if
necessary
Important:
–
Felling notch at right angle to
direction of fall
–
As close to the ground as possible
–
cut to a depth of approx. 1/5 to 1/3
of the diameter of the trunk
Sapwood cuts
With long-fibered wood, sapwood cuts
prevent the sapwood from splintering
when felling the trunk – saw both sides
of the trunk at the level of the felling
notch base to approx. 1/10 of the
diameter of the trunk – with thicker
trunks, not more than the width of the
guide bar.
Do not use sapwood cuts on diseased
trees.
