20 Felling Cut for Large Diameter Trees
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.
Sectioning Method

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...

Risk of pinching! Always start relieving 
cut (1) at compression side.Then make 
bucking cut (2) at tension side. If the saw 
pinches, stop the engine and remove it 
from the log.
Only properly trained professionals 
should work in an area where the logs, 
limbs and roots are tangled. Working in

Chain scabbard
Your saw comes standard with a chain 
scabbard that matches the cutting 
attachment.
If you use guide bars of different lengths 
on the saw, the length of the chain 
scabbard must be matched to the guide 
bar to help reduce the risk of injury. It 
should cover the full length of the guide 
bar.
The length of the matching guide bars is 
marked on the side of the chain 
scabbard.
