18CS-450PFELLING THE TREEA falling tree can seriously damage anything it mayhit - a car, a house, a fence, a power-line, oranother tree.There are ways to make a tree fall where you wantit, so first decide where that is!Before cutting, clear the area around the tree.You will need good footing while working and youshould be able to work the saw without hitting anyobstacles.Next, select a path of retreat.When the tree begins to fall you should retreataway from the direction of fall at a 45-degree angleand at least 3 m from the trunk to avoid the trunkkicking back over the stump.Begin the cut on the side to which the tree is to fall.Cut a notch about 1/3 of the way into the tree. Theposition of this notch is important since the tree willtry to fall “into” the notch.The felling cut is made on the side opposite thenotch and at a level about 5 cm above the bottomof the notch.Do not try to cut through to the notch with the fellingcut.The remaining wood between the notch cut andfelling cut about 5 cm will act as a hinge when thetree falls, guiding it in the desired direction.When the tree starts to fall, kill the engine, placethe saw on the ground and make your retreatquickly.To fell big trees with a diameter exceeding twice thebar length, start the notching cuts from one sideand draw the saw through to the other side of thenotch.Start the back cut on one side of the tree, pivotingthe saw through to form the desired hinge on thatside.Then remove the saw for the second cut. Insert thesaw in the first cut, very carefully so as not tocause kickback.The final cut is made by drawing the saw forward inthe cut to reach the hinge.5 cm123Felling cutHingeDirection of fallFirst cutNotchSecond cutOne-third tree diameterDirection of fall45°45°Not this wayRetreatRetreat3 m5 cm
