Escape paths
Establish paths of escape for
–
everyone concerned – opposite to
direction of fall at about 45°.
Remove all obstacles from escape
–
paths.
Place all tools and equipment a safe
–
distance away from the tree, but not
on the escape paths.
Always keep to the side of the falling
–
tree and only walk away along the
preplanned escape path.
On steep slopes, plan escape
–
routes parallel to the slope.
When walking away along the
–
escape path, watch out for falling
limbs and watch the top of the tree.
Preparing work area at base of tree
First clear the tree base and work
–
area from interfering limbs and
brush to provide a secure footing.
Clean lower portion of tree base
–
(e.g. with an axe) – sand, stones
and other foreign objects will dull the
saw chain.
Remove large buttress roots: Make
–
the vertical cut first, then the
horizontal – but only if the wood is
sound

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.
C
C
The felling notch (C) determines the
direction of fall.
STIHL recommends the following
method:
Make the horizontal cut – check the
N
direction of fall with the gunning
sight.
Make angle cut at about 45°.
N
Check the felling notch and correct it
N
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.
