Felling notch
When making the felling notch, make
use of the gunning sight on the shroud
and fan housing to check the planned
direction of fall.
Position your saw so that the gunning
sight points in exactly the direction you
want the tree to fall.
There are several approved methods for
making the felling notch – observe
country-specific regulations on felling
techniques.
The felling notch (C) determines the
direction of fall.
STIHL recommends the following
method:
N
Make the horizontal cut – check the
direction of fall with the gunning
sight.
N
Make angle cut at about 45°.
N
Check the felling notch and correct it
if necessary.
Important:
–
Felling notch at a right angle to the
planned direction of fall.
–
As close to the ground as possible.
–
Cut to a depth of about 1/5 to 1/3 of
the trunk diameter.
Sapwood cuts
Sapwood cuts in long-fibered softwood
help prevent sapwood splintering when
the tree falls. Make cuts at both sides of
the trunk at same height as bottom of
felling notch to a depth of about 1/10 of
trunk diameter. On large diameter trees,
cut to no more than width of guide bar.
Do not make sapwood cuts if wood is
diseased.
