Tree felling technique

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!

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.

Trees should not be felled in a manner that would endanger any person, strike any utility line or cause any property damage. If the tree does make contact with any

utility line, the utility company should be notified immediately.

During tree maintenance work above ground level, the working area must always be secured and marked out with signs, tape or the like.

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

•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.

•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.

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.

WARNING! During critical felling

! operations, hearing protectors should be

lifted immediately when sawing is completed so that sounds and warning signals can be heard.
