Before you go through the threatening steps of tree removal, you should first make sure that everything has been set up in such a fashion that it will not inflict injury on you and on surrounding resources and foundations. The fact that such an undertaking has been dubbed a "widow maker" shouldn't be shrugged off. Here are the main steps of tree removal with their corresponding safety checks.
Directing the Tree
It's best to permit the tree to fall in the direction where it is naturally leaning. While it's possible to let the tree fall in the alternative direction, it is not advised for a DIY tree removal project. Should you insist strongly upon letting it fall in a direction other than where it is naturally leaning, you'll do so with the use of ropes. Employ a ladder to tie the ropes in the right places, and pull on them as the tree falls. Ensure you also have the right exit plan.
The Face Cut
In tree removal, the face cut determines the direction where the tree will fall. First, make a cut that is parallel to the ground and is about two thirds throughout the whole width of the tree. Make sure that this cut has been made in the direction where you intend to let the tree fall. The second cut is created at a 45-degree angle above the first cut. The ends of the cut should meet. If they don't, the tree could most likely split vertically as it falls. If you've done this properly, you ought to be able to remove a wedge-shaped piece from the cuts.
The Back Cut
The back cut is the second and final cut in the tree removal process. This is a horizontal cut that's done 1 to 2 inches at the rear of the nick. Slowly cut it, and ensure you are making a cut that is continually parallel to the ground. Do not cut all the way through, and leave about one-tenth of the whole diameter of the tree.
After you have done the mandatory cuts, the tree will begin to fall. If you have tied ropes on the tree, ask your assistant to tug at them to direct it into the area where it should fall. After the tree removal is complete, do the required cleanup and send the timber to its appointed places.
