WORKING TECHNIQUES
much greater risk that the kickback zone of the bar will
come into contact with the tree.
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.
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.
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 try to fell the tree that is trapped.
Never cut straight through a tree or branch that is in
tension!
If you must cut across tree/limb, make two to three cuts,
one inch apart, one to two inches deep.
Never work in the risk zone of the hanging trapped tree.
Continue to cut deeper until tree/limb bends and tension
is released.
Cut tree/limb from outside the bend, after tension has
been released.
The safest method is to use a winch.
How to avoid kickback

WARNING! Kickback can happen very suddenly
and violently; kicking the chain saw, bar and

chain back at the user. If this happens when the
chain is moving it can cause very serious, even
fatal injuries. It is vital you understand what

What is kickback?
Cutting trees and branches that are in tension
The word kickback is used to describe the sudden
reaction that causes the chain saw and bar to jump off an
object when the upper quadrant of the tip of the bar,
known as the kickback zone, touches an object.
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).
