WORKING TECHNIQUES
Felling direction
Clearing the trunk and preparing your retreat
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.
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.
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.

Danger zone
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.
Felling
WARNING! Unless you have special
training we advise you not to fell trees
with a diameter larger than the bar length
of your saw!
!
The main point to avoid is letting the tree fall onto another
tree. It is very dangerous to remove a trapped tree and
there is high accident risk. See instructions under the
heading Freeing a tree that has fallen badly.
Felling is done using three cuts. First you make the
directional cuts, which consist of the top cut and the
bottom cut, then you finish with the felling cut. By placing
these cuts correctly you can control the felling direction
very accurately.
Directional cuts
To make the directional cut you begin with the top cut.Aim
using to the saw’s felling direction mark (1) toward a goal
further forward in the terrain, where you would like the tree
to fall (2). Stand on the right-hand side of the tree, behind
the saw, and cut with a pull stroke.
IMPORTANT! During critical felling operations, hearing
protectors should be lifted immediately when sawing is
completed so that sounds and warning signals can be
heard.
