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.

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.
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.
Continue to cut deeper until tree/limb bends and tension 
is released.
Cut tree/limb from outside the bend, after tension has 
been released.
How to avoid kickback
What is kickback?
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.
!
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 
causes kickback and that you can avoid it by 
taking care and using the right working 
technique.
