Bucking 010941 For bucking cuts, rest the serrated rail shown in the figure on the wood to be cut. With the saw chain running, saw into the wood, using the top handle to raise the saw and the front one to guide it. Use the serrated rail as a pivot. Continue the cut by applying slight pressure to the front handle, easing the saw back slightly. Move the serrated rail further down the timber and raise the front handle again. When making several cuts, switch the chain saw off between cuts. Limbing CAUTION: • Limbing may only be performed by trained persons. A hazard is presented by the risk of kick-back. When limbing, support the chain saw on the trunk if possible. Do not cut with the tip of the bar, as this presents a risk of kickback. Pay particular attention to branches under tension. Do not cut unsupported branches from below. Do not stand on the felled trunk when limbing. Burrowing and parallel-to-grain cuts CAUTION: • Burrowing and parallel-to-grain cuts may only be carried out by persons with special training. The possibility of kickback presents a risk of injury. 006914 CAUTION: • If the upper edge of the bar is used for cutting, the chain saw may be deflected in your direction if the chain becomes trapped. For this reason, cut with the lower edge, so that the saw will be deflected away from your body. 010942 Perform parallel-to-grain cuts at as shallow an angle as possible. Carry out the cut as carefully as possible, as the serrated rail cannot be used. Felling CAUTION: • Felling work may only be performed by trained persons. The work is hazardous. Observe local regulations if you wish to fell a tree. 1. Felling area 45o A B B A 006915 Cut wood under tension on the pressure side (A) first. Then make the final cut on the tension side (B). This prevents the bar from becoming trapped. 2 1/2 45o 1 006917 − Before starting felling work, ensure that: (1) Only persons involved in the felling operation are in the vicinity; (2) Any person involved has an unhindered path of retreat through a range of approximately 45 ° either side of the felling axis. Consider the additional risk of tripping over electrical cables; (3) The base of the trunk is free of foreign objects, roots and ranches; 12
