A = Direction of fall
B = 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
with an axe. Sand, stones and other
foreign objects will dull the saw
chain.
– Remove large buttress roots: Make
vertical cut first, then horizontal –
but only if wood is sound.
Felling notch
When making the felling notch, make
use of the gunning sight on the shroud
and housing to check the planned
direction of fall.
Position your saw so that the gunning
sight points in exactly in 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.
STIHL recommends the following
method:

A

B
