Limbing CAUTION: Limbing may only be performed by trained persons. A hazard is presented by the risk of kickback. 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. Perform parallel-to-grain cuts at as shallow an angle as possible. Take an extra caution when carrying out the cut as the spike bumper cannot be used. • The base of the trunk is free of foreign objects, roots and ranches; • No persons or objects are present over a distance of 2 1/2 tree lengths in the direction in which the tree will fall. - Consider the following with respect to each tree: • Direction of lean; • Loose or dry branches; • Height of the tree; • Natural overhang; • Whether or not the tree is rotten. - Consider the wind speed and direction. Do not carry out felling work if the wind is gusting strongly. - Trimming of root swellings: Begin with the largest swellings. Make the vertical cut first, then the horizontal cut. - Stand to the side of the falling tree. Keep an area clear to the rear of the falling tree up to an angle of 45° either side of the tree axis (refer to the "felling area" figure). Pay attention to falling branches. - 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. 1 2 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. 45 o 2 1/2 45 o 1 3 3 2 ► 1 . Felling direction 2. Danger zone 3. Escape route When felling trees, follow the procedures below: 1. Cut a scarf as close to the ground as possible. First make the horizontal cut to a depth of 1/5 -1/3 of the trunk diameter. Do not make the scarf too large. Then make the diagonal cut. ► 1 . Felling area - Before starting felling work, ensure that: • Only persons involved in the felling operation are in the vicinity; • 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; NOTE: The scarf determines the direction in which the tree will fall, and guides it. It is made on the side towards which the tree is to fall. 14 ENGLISH
