Making sapwood cuts • For medium sized or larger trees make cuts at both sides of the trunk, • at same height as subsequent felling cut. • Cut to no more than width of guide bar. This is especially important in soft wood in summer - it helps prevent sapwood splintering when the tree falls. 20 001BA043 LÄ 001BA044 LÄ 001BA045 LÄ B = Felling cut 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. !Warning! 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. C = Hinge Helps control the falling tree •• Do not cut through the hinge you could lose control of the direction of the fall !Warning! 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.
