WORKING TECHNIQUES
28 – English
When the felling cut and directional cut are complete the 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.
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.
Freeing a tree that has fallen badly
Freeing a ”trapped tree”
It is very dangerous to remove a trapped tree and there is
high accident risk.
Never try to fell the tree that is trapped.
Never work in the risk zone of the hanging trapped tree.
The safest method is to use a winch.
• Tractor-mounted
• Portable
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).
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.
General advice:
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.
