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.

Portable

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.

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.

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.

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.

Kickback always occurs in the cutting plane of the bar. 
Normally the chain saw and bar are thrown backwards 
and upwards towards the user. However, the chain saw 
may move in a different direction depending on the way it 
was being used when the kickback zone of the bar 
touched the object.
