limbing, and cross-cutting BB.1 Felling a tree When bucking and felling operations are being performed by two or more persons at the same time, the felling operations should be separated from the bucking operation by a distance of at least twice the height of the tree being felled Trees should not be felled in a manner that would endanger any person, strike any utility line or cause any property damage If the tree does make contact with any utility line, the company should be notified immediately The chain saw operator should keep on the uphill side of the terrain as the tree is likely to roll or slide downhill after it is felled An escape path should be planned and cleared as necessary before cuts are started The escape path should extend back and diagonally to the rear of the expected line of fall as illustrated in Figure BB.101 Before felling is started, consider the natural lean of the tree, the location of larger branches and the wind direction to judge which way the tree will fall Remove dirt, stones, loose bark, nails, staples and wire from the tree BB.2 Notching undercut Make the notch 1/3 the diameter of the tree, perpendicular to the direction of falls as illustrated in Figure BB.102 Make the lower horizontal notching cut first This will help to avoid pinching either the saw chain or the guide bar when the second notch is being made BB.3 Felling back cut Make the felling back cut at least 50 mm higher than the horizontal notching cut as illustrated in Figure BB.102 Keep the felling back cut parallel to the horizontal notching cut Make the felling back cut so enough wood is left to act as a hinge The hinge wood keeps the tree from twisting and falling in the wrong direction Do not cut through the hinge As the felling gets close to the hinge, the tree should begin to fall If there is any chance that the tree may not fall in desired direction or it may rock back and bind the saw chain, stop cutting before the felling back cut is complete and use wedges of wood, plastic or aluminium to open the cut and drop the tree along the desired line of fall When the tree begins to fall remove the chain saw from the cut, stop the motor, put the chain saw down, then use the retreat path planned Be alert for overhead limbs falling and watch your footing – 31 – BB.4 BS EN 60745-2-13:2009+A1:2010 EN 60745-2-13:2009+A1:2010 (E) Limbing a tree Limbing is removing the branches from a fallen tree When limbing leave larger lower limbs to support the log off the ground Remove the small limbs in one cut as illustrated in Figure BB.103 Branches under tension should be cut from the bottom up to avoid binding the chain saw BB.5 Bucking a log Bucking is cutting a log into lengths It is important to make sure your footing is firm and your weight is evenly distributed on both feet When possible, the log should be raised and supported by the use of limbs, logs or chocks Follow the simple directions for easy cutting When the log is supported along its entire length as illustrated in Figure BB.104, it is cut from the top (overbuck) When the log is supported on one end, as illustrated in Figure BB.105, cut 1/3 the diameter from the underside (underbuck) Then make the finished cut by overbucking to meet the first cut When the log is supported on both ends, as illustrated in Figure BB.106, cut 1/3 the diameter from the top (overbuck) Then make the finished cut by underbucking the lower 2/3 to meet the first cut When bucking on a slope always stand on the uphill side of the log, as illustrated in Figure BB.107 When “cutting through”, to maintain complete control release the cutting pressure near the end of the cut without relaxing your grip on the chain saw handles Don’t let the chain contact the ground After completing the cut, wait for the saw chain to stop before you move the chain saw Always stop the motor before moving from tree to tree BS EN 60745-2-13:2009+A1:2010 EN 60745-2-13:2009+A1:2010 (E) – 32
