745°45°= cutting down range21161718192CAUTIon:Do not fell or debranch trees unless you are speciallytrained for it! There is a high risk of injury! Make sure tofollow local regulations.- Before cutting down a tree ensure thata) only those persons are within the working range which areactually involved in cutting down the treeb) all persons involved in the felling have an unhindered retreatroute (the retreat path should be about 45° diagonally andto the rear away from the direction of fall). Be aware of theincreased risk of stumbling from electric cables!c) the bottom part of the trunk is free from foreign bodies, un-derbrush and branches. Make sure to have a safe footing(risk of stumbling).d) the next working place is at least 1/ tree lengths away(16). Before cutting down the tree check the direction of falland make sure that there are neither other persons nor anyobjects within a distance of 1/ tree lengths (16).- Judging the tree:Direction of hanging - loose or dry branches - height of the tree- natural hang over - is the tree rotten?- Take into account the direction and the velocity of the wind.If strong gusts are occuring, do not perform any cutting downworks.- Cutting the roots:Start with the strongest root. First perform the vertical and thenthe horizontal cut.- Notching the trunk (A, 17):The notch determines the direction of fall and guides the tree.The trunk is notched perpendicular to the direction of fall andpenetrates 1/3 -1/5 of the trunk diameter. Perform the cut nearthe ground.- When correcting the cut always do so over the whole width ofthe notch.- Cut down the tree (B, 18) above the bottom edge of the notch(D). The cut must be exactly horizontal. The distance betweenboth cuts must be approx. 1/10 of the trunk diameter.- The material between both cuts (C) serves as a hinge. Nevercut it through, otherwise the tree will fall without any control.Insert felling wedges in the cut (B, 18) in good time.- Secure the cut only with wedges made of plastic or aluminium.Do not use iron wedges.- When cutting down a tree always stay sideways of the fallingtree.- When withdrawing after having performed the cut down beaware of falling branches.- When working on a sloping ground the user of the electric chainsaw must stay above or sidewards of the trunk to be cut or thealready cut down tree.- Be aware of trunks which may roll towards you.Kickback- When working with the electric chain saw dangerous kickbacksmay occur.- Kickback occurs when the tip of the blade(especially the topquarter) inadvertently comes into contact with wood or othersolid objects.- In this case the electric chain saw is thrown without any controland with high energy potentials in the direction of the user (riskof injuries).In order to prevent kickbacks follow the indicated instruc-tions:- Never apply the end of the bar when starting to make a cut.Always observe the end of the bar.- Never use the bar end for sawing. Be careful when continuingto cut.- When starting to perform a cut the chain must be running.- Ensure that the chain is always sharpened correctly. Pay specialattention to the hight of the depth limiter (for detailed informationsee the chap. "Sharpening the saw chain").- Never cut several branches at the same time. When cutting abranch ensure that no other branch is touched.- When crosscutting a trunk be aware of the trunks next to it. Itis recommended to use a saw jack.AA 45oBBCCD
