7= cutting down area1617181945 o2 1 /245 o15- Be careful when cutting splintery wood. Cut pieces of woodmay be pulled along (risk of injuries).- When cutting with the upper edge of the guide bar, the chainsaw may be pushed in the direction of the user if the chaingets clamped. For this reason use the lower edge of the barwhenever possible. The chain saw will then be pushed awayfrom you (15).- If the timber is under tension (16), first cut the pressure side(A). Then the crosscut can be performed on the tension side(B). Thus clamping of the guide bar can be avoided.CAUTION:People felling trees or cutting of branches must be speciallytrained. High risk of injuries!- When cutting of branches, the chain saw should be supportedon the trunk. Do not use the end of the bar for cutting (risk ofkickback).- Be aware of branches under tension. Do not cut free branchesfrom below.- Never perform detensioning cuts while standing on the trunk.- Before cutting down a tree ensure thata) only those people are within the working area which areactually involved in cutting down the tree.b) every worker involved can withdraw without stumbling (thepeople should withdraw backwards in a diagonal line, i. e.at a degree of 45°).c) the bottom part of the trunk is free from foreign objects,underbrush and branches. Make sure to have a safe footing(risk of stumbling).d) the next working place is at least 2 1/2 tree lengths away(17). Before cutting down the tree check the direction of falland make sure that there are neither people nor objectswithin a distance of 2 1/2 tree lengths.- Judging the tree:Direction of hanging - loose or dry branches - height of the tree- natural overhang - is the tree rotten?- Take into account the direction and speed of the wind. If stronggusts are occurring, do not do any felling.- Cutting the roots:Start with the strongest root. First do the vertical and then thehorizontal cut.- Notching the trunk (18, A):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 (19, B) 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 time.- Secure the cut only with wedges made of plastic or aluminium.Do not use iron wedges. If the saw hits an iron wedge the chaincan be seriously damaged or torn.- When cutting down a tree always stay sidewards of the fallingtree.- When withdrawing after having performed the cut, be alert forfalling branches.- When working on sloping ground the user of the chain sawmust stay above or sidewards of the trunk to be cut or the treealready cut down.- Be alert for trunks which may roll towards you.
