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.

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.

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.
