WORKING TECHNIQUES
When the felling cut and directional cut are complete the tree
Never work in the risk zone of the hanging trapped tree.
should start to fall by itself or with the aid of a felling wedge or
breaking bar.
We recommend that you use a bar that is longer than the
diameter of the tree, so that you can make the felling cut and
directional cuts with single cutting strokes. See instructions
under the heading Technical data section to find out which
lengths of bar are recommended for your saw.
The safest method is to use a winch.

Portable
There are methods for felling trees with a diameter larger than
the bar length. However these methods involve a much
greater risk that the kickback zone of the bar will come into
contact with the tree.
Cutting trees and branches that are in tension
Preparations:Work out which side is in tension and where the
point of maximum tension is (i.e.where it would break if it was
bent even more).
Freeing a tree that has fallen badly
Decide which is the safest way to release the tension and
whether you are able to do it safely. In complicated situations
the only safe method is to put aside your chain saw and use
a winch.
Freeing a ”trapped tree”
It is very dangerous to remove a trapped tree and there is high
accident risk.
General advice:
Never try to fell the tree that is trapped.
Position yourself so that you will be clear of the tree or branch
when the tension is released.
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.
Never cut straight through a tree or branch that is in
tension!
