The log is supported at one end. There is a high risk that it 
will split.

Start by cutting from below (about 1/3 of the way through).

   - Finish by cutting from above so that the two cuts meet.

The log is supported at both ends. There is a high risk that 
the chain will jam.

   - Start by cutting from above (about 1/3 of the way through).

   - Finish by cutting from below so that the two cuts meet.

When limbing thick branches you should use the same 
approach as for cutting.

Cut difficult branches piece by piece.

During tree maintenance work above ground level, the 
working area must always be secured and marked out with 
signs, tape or the like. The safe distance between the top of 
the tree that is to be felled and the nearest workplace must be 
at least 2 1/2 times the height of the tree. Make sure that no-
one else is in this risk zone before or during felling.

The aim is to fell the tree in a position where you can limb and 
cross-cut the log as easily as possible. You want it to fall in a 
location where you can stand and move about safely. The 
main thing to avoid is that the falling tree top should get 
jammed in another tree. Taking down a ”jammed” tree top is 
very dangerous (see point 4 in this section).

Once you have decided which way you want the top of the 
tree to fall you must assess which way the top of the tree 
would fall naturally.

Several factors affect this:

•

Lean of the tree

•

Bend

•

Wind direction

•

Arrangement of branches

•

Weight of snow

You may find you are forced to let the tree fall in its natural 
direction because it is impossible or dangerous to try to make 
it fall in the direction you first intended.

Another very important factor, which does not affect the felling 
direction but does affect your safety, is to make sure the tree 
has no damaged or dead branches that might break off and 
hit you during felling.
