WORKING TECHNIQUES
Tree felling technique
is high accident risk. See instructions under the heading
Freeing a tree that has fallen badly.
IMPORTANT! It takes a lot of experience to fell a tree.
Inexperienced users of chain saws should not fell trees.Do
not attempt any task beyond your experience level!
Safe distance
The safe distance between a tree that is to be felled and
anyone else working nearby is at least 2 1/2 tree lengths.
Make sure that no-one else is in this ”risk zone” before or
during felling.
IMPORTANT! During critical felling operations, hearing
protectors should be lifted immediately when sawing is
completed so that sounds and warning signals can be
heard.
Clearing the trunk and preparing your retreat
Delimb the stem up to shoulder height. It is safer to work
from the top down and to have the tree between you and the
saw.
Felling direction
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.
Once you have decided which way you want the tree to fall
you must judge which way the tree would fall naturally.
Several factors affect this:
•
•
•
•
•
•
Lean of the tree
Bend
Wind direction
Arrangement of branches
Weight of snow
Remove any undergrowth from the base of the tree and
check the area for obstacles (stones, branches, holes, etc.)
so that you have a clear path of retreat when the tree starts
to fall.Your path of retreat should be roughly 135 degrees
away from the intended felling direction.
Obstacles within the reach of the tree: for example, other
trees, power lines, roads and buildings.
•
Look for signs of damage and rot in the stem, this makes
it more probably that the tree will break and start to fall
before you expect it to.

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.
The main point to avoid is letting the tree fall onto another
tree. It is very dangerous to remove a trapped tree and there
