There are methods for felling trees with a diameter
larger than the guide bar length. However these
methods involve a much greater risk that the kickback
zone of the guide bar will come into contact with the
tree.
To free a badly fallen tree
It is very dangerous to remove a trapped tree and there
is a high accident risk. The safest method is to use a
winch:
• Tractor-mounted
• Portable
WARNING: Never try to fell a tree that is
trapped and never work in the risk zone of
the hanging trapped tree.

To cut trees and branches that are in tension
1. Figure out which side of the tree or branch that is in
tension and where the point of maximum tension is,
for instance where it would break if it was bent even
more.
2. Decide which is the safest way to release the tension
and whether you are able to do it safely
Note: In complicated situations the only safe method
is to put aside your chainsaw and use a winch.
3. Position yourself so that you will be clear of the tree
or branch when the tension is released.
4. Make one or more cuts at or near the point of
maximum tension. Make as many cuts of sufficient
depth as necessary to reduce the tension and make
the tree or branch break at the point of maximum
tension.
WARNING: Never cut straight through a
tree or branch that is in tension.
