Cutting Trees or Limbs Under Tension.

CAUTION!

Cutting trees or limbs under tension involves spesial hazards and must be done with care and planning. If the cut is made improperly, or you are in the wrong position, the tree may spring back at you and cause severe injury

The cut should be made at the tree’s breaking point: i.e., the point where the tree would break if it was bent further. That point is normally where the bend is most pronounced. At the breaking point, the forces are mainly trying to push the tree outward. If you are not cutting at the breaking point, the longest section of the stem, besides trying to push outwards, will also try to push along the trunk after it has broken. That makes the forces harder to predict and increases the danger.

STOP WARNING!

Using improper techniques while cutting trees or limbs under tension can be extremely dangerous.

The instructions above cover basic procedures but do not cover all possible situations you may encounter, such as multiple trees entangled in each other, dry wood, etc. Use extreme caution. Improper use may cause severe injury. Do not hesitate to get help if necessary.
