Kickback WARNING DANGER Do not let the tip of the bar touch anything while the engine is running.

Avoid it! 12 FELLING A TREE DIRECTION OF FALL WARNING DANGER A falling tree can seriously damage anything it may hit - a car, a house, a fence, a power line, or another tree. There are ways to make a tree fall where you want it, so first decide where that is!You will need good footing while working and you should be able to work the saw without hitting any obstacles. When the tree begins to fall you should retreat away from the direction of fall at a 45 degree angle to avoid the trunk kicking back over the stump. Hinge 45° Direction of fall 2" First cut Felling cut Notch Second cut One-third tree diameter 2" Begin the cut on the side to which the tree is to fall. The position of this notch is important since the tree will try to fall "into" the notch. The felling cut is made on the side opposite the notch and at a level about 2" above the bottom of the notch. The remaining wood between the notch cut and felling cut (about 2") will act as a hinge when the tree falls, guiding it in the desired direction.
