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.

Limbing
When limbing thick branches you should use the same
approach as for cutting.
WORKING TECHNIQUES
Cut difficult branches piece by piece.
Felling technique for tree tops
WARNING! 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
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.
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. 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
