First, consider whether the area has any significant obstacles, such as overhead lines, roads, or buildings. Put up warning signs if you know that a road crosses the forest area or that many people pass through it daily.

Continue by determining the direction of the fall through careful examination of the tree. What do the branches look like and how do they grow? Also take into account the wind direction. If you are unsure of the natural fall direction of the tree, move away from the tree and check with a plumb bob (see the facts box for details). Clear the area around the tree in the intended direction of fall. Also clear the 45 degree space behind the tree in both directions, to provide a retreat path. From the Australian Timber Trainers Association this is the most important factor

Prune the trunk

When you have cleared the area, installed your warning signs, and decided on the direction of the tree fall and your retreat path, you need to verify that you have enough fuel in the tank for the task at hand. Then, you need to prune the trunk to remove all the branches and branches that could bother you when cutting the felling line. The safest way to prune is to work with a pull chain (under the guide bar) from top to bottom. Find out how to safely and effectively delimb a tree.

Choose the cutting technique

When the trunk no longer has twigs up to shoulder height, the slaughter line should be made. There are two things to remember when doing this: the hinge must be of uniform thickness with the correct dimensions, and the wedge or felling lever must be inserted before the tree can pinch the guide bar. The technique to be used to make the cut depends on the size of the tree and the slope, as well as the dimensions of the chainsaw used for felling. We've gathered some information on the different techniques here, so you can find the best method for your conditions.

Chainsaw cutting technique

If you find that the wood is discolored and soft or if the lower part of the trunk appears swollen or sick, you should be very careful. This indicates that the tree is rotten and that the fibers of the wood are less strong. In this type of situation, cut down the tree in the direction of natural fall and use a winch if in doubt. Rot usually stays higher up in the tree, so it may be possible to cut down the tree with a higher stump.

Choose your tools

There are several felling tools from which to choose for felling the tree. The size of the tree determines the type of forestry equipment needed. For smaller trees, you don't normally need the felling tools. Physical strength is enough, possibly using a long pole . The felling wedge provides greater felling strength than the different types of felling levers. In extreme cases, you can use a rope and a winch, which is the safest and most powerful method of cutting down a tree. See the fact insert for more information on the different tools.
