OPERATION work area. Follow the correct tree felling procedure as stated in Proper Procedure For Tree Felling after you have removed the large buttress roots. BUCKING See Figure 26. Bucking is the term used for cutting a fallen tree to the desired log length. n Cut only one log at a time. n Support small logs on a saw horse or another log while bucking. n Keep a clear cutting area. Make sure that no objects can contact the guide bar nose and chain during cutting, this can cause kickback. To avoid the danger, keep the SAFE-T-TIP® anti-kickback device attached while cutting. Refer to Kickback in the Specific Safety Rules section of this manual for more information. ■n During bucking operations, stand on the uphill side so that the cut-off section of the log cannot roll over you. ■n Sometimes it is impossible to avoid pinching (with just standard cutting techniques) or difficult to predict which way a log will settle when cut. BUCKING WITH A WEDGE See Figure 27. If the wood diameter is large enough for you to insert a soft bucking wedge without touching the chain, you should use the wedge to hold the cut open to prevent pinching. NOTE: When bucking or felling with a wedge, you may need to remove the SAFE-T-TIP® anti-kickback device to allow the bar to be drawn through the cut. After you complete the cut, reinstall the tip.
