C. BUCKING Bucking is the tern., used for cutting a fallen tree to the desired log size. I. IMPORTANT POINTS a. Cut only one log at a time. h. Cut shattered wood very carefully. Sharp pieces of wood could be flung toward operator. c. Use a sawhorse to cut small logs. Never allow another person to hold the log while cutting and never hold the log with your leg or foot. d.Do not cut in an area where logs, limbs, and roots are tangles such as in a blown down area. Drag the logs into a clear area before cutting by pulling out exposed and cleared logs first. e. Give special attention to logs under strain to prevent the saw from pinching. Make the first cut on the pressure side to relieve the stress on the log. Figure 24. 2. TYPES OF CUTTING USED (Figure 25) - Overcutting - begin on the top side of the log with the bottom of the saw against the log: exert light pressure downward. - Undercutting - begin on the under side of they log with the top of the saw against the log, exert ligh pressure upward. During undercutting, the saw will tend to push back at you. Be prepared for this reac tin n and hold the saw firmly to maintain control. A WARNING Never turn the saw upside down to undercut. The saw cannot be controlled in this position. A WARNING If saw becomes pinched or hung in a log, don't try to force it out. You can lose control of the saw resulting in injury and/or damage to the saw. Stop the saw, drive a wedge of plastic or wood into the cut until the saw can be removed easily. Figure 26. Restart the saw and carefully re-enter the cut. To avoid kickback and chain damage, do not use a metal wedge. Do not attempt to restart your saw when it is pinched or hung in a log. 3.
