Removing large and heavy branches is technically quite difficult, which cannot be held during cutting. Failure to perform such a cut often leads to very large damage. The correct way is to cut off the branches first at a fairly long distance from the root, and then removing the remaining root.
All cuts should be made carefully, using only suitable and well-sharpened tools. Blurred balls cause large irregularities in the wood, fraying and tearing off the bark at the edges of the wound, as a result, it grows much more difficult.
Work related to the removal of branches, they are often dangerous for people who lead them and passers-by at high altitudes, who may find themselves under the tree. Therefore, this work should only be carried out by properly trained employees, equipped with the right tools and using appropriate safeguards for work at great heights.
It should not be possible to walk or drive under trees during the works by setting up barriers, placing warning notices. If the movement cannot be stopped, large branches should not be allowed to fall, but you must strap them up and lower them slowly.
