SAFETY INSTRUCTIONS
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.
Cut difficult branches piece by piece.
Tree felling technique
Safe distance
The safe distance between a tree that is to be felled and
anyone else working nearby is at least 21/2 tree lengths.
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 on
ground where you can stand and move about safely. The main
point to avoid is letting the tree fall onto another tree. See
instructions under the heading Freeing a tree that has fallen
badly.
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
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.

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
that you feel unsure of!
