To calculate the felling direction

Examine in which direction it is necessary for the tree to fall. The goal is to fell it in a position where you can limb and cut the trunk easily. It is also important that you are stable on your feet and can move about safely.

WARNING: Let the tree fall in its natural fall direction if it is not possible or dangerous to fell it differently.
Examine the natural fall direction of the tree. For example the tilt and bend of the tree, wind direction, the location of the branches and weight of snow.
Examine if there are obstacles, for example other trees, power lines, roads and/or buildings around.
Look for signs of damage and rot in the stem.

WARNING: Rot in the stem can mean a risk that the tree falls before you complete the cutting.
Make sure the tree has no damaged or dead branches that can break off and hit you during felling.
Do not let the tree fall onto a different tree. It is dangerous to remove a trapped tree and there is a high accident risk. See To free a trapped tree.

WARNING: During critical felling operations, lift your hearing protection immediately when the sawing is complete. It is important that you hear sounds and warning signals.
