Stihl 038 - Felling cut for large diameter trees: sectioning method; Felling cut for small diameter trees: simple fan cut

C= Hinge
© Helps control the falling tree
@® Donot cut through the hinge — you
could lose control of the direction of
the fall .
Warning!
In order to reduce the risk of personal
injury, never stand directly behind the
tree when it is about to fall, since part of
the trunk may split and come back
towards the operator (barber-chairing),
or the tree may jump backwards off the
stump. Always keep to the side of the
falling tree. When the tree starts to fall,
withdraw the bar, shut off the engine and
walk away on the preplanned escape
path. Watch out for falling limbs.

Warning!
Be extremely careful with partially fallen
trees which are poorly supported.
When the tree hangs or for some other
reason does not fall completely, set the
saw aside and pull the tree down with a
cable winch, block and tackle or tractor.
If you try to cut it down with your saw,
you may be injured.
Felling cut for small diameter trees:
simple fan cut
Engage the bumper spikes of the chain-
saw directly behind the hinge and pivot
the saw around this point only as far as
the hinge. The spiked bumper rolls
against the trunk.

Felling cut for large diameter trees:
sectioning method
Warning!
Felling a tree that has a diameter greater
than the length of the guide bar requires
use of either the sectioning felling cut or
plunge-cut method. These methods are
extremely dangerous because they
involve the use of the nose of the guide
bar and can result in kickback. Only
properly trained professionals should
attempt these techniques.
For the sectioning method make the first
part of the felling cut with the guide bar
fanning in toward the hinge. Then, using
the bumper spike as a pivot, reposition
the saw for the next cut.
