•Conventional and open-face technique: Begin 1 to 2 inches higher than center of felling notch • Cut horizontalIy towards the felling notch • Leave approx.1/10 of diameter uncut. • This is the hinge Do not cut through the hinge - you could lose control of the direction of the fall Drive wedges into the felling cut where necessary to control the fall. If the tip of the bar contacts a wedge, it may cause kickback. Wedges should be of wood or plastic - never steel, which can damage the chain. 001BA044 LÄ 001BA045 LÄ 001BA046 LÄ Helps control the falling tree •• Do not cut through the hinge - you could lose control of the direction of the fall In order to reduce the risk of personal injury, never stand directly behind the tree when it is about to fall, since part of the trunk may split and come back towards the operator (barber- chairing), or the tree may jump backwards off the stump. Always keep to the side of the falling tree. When the tree starts to fall, withdraw the bar, shut off the engine and walk away on the preplanned escape path. Watch out for falling limbs. Be extremely careful with partially fallen trees which are poorly supported. When the tree hangs or for some other reason does not fall completely, set the saw aside and pull the tree down with a cable winch, block and tackle or tractor. If you try to cut it down with your saw, you may be injured. Engage the bumper spikes of the chainsaw directly behind the hinge and pivot the saw around this point only as far as the hinge. The spiked bumper rolls against the trunk.
