Then insert soft wooden or plastic wedges into the cut so they do not touch the chain. Drive wedges in, little by little, to help jack the tree over. n When bucking or felling with a wedge, it may be necessary 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 immediately. n As tree starts to fall, stop the chain saw and put it down immediately. Retreat along the cleared path, but watch the action in case something falls your way. WARNING: Never cut through to the notch when making a back cut. The hinge controls the fall of the tree, this is the section of wood between the notch and backcut. REMOVING BUTTRESS ROOTS See Figure 25. A buttress root is a large root extending from the trunk of the tree above the ground. Remove large buttress roots prior to felling. Make the horizontal cut into the buttress first, followed by the vertical cut. Remove the resulting loose section from the 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. HINGE BACK CUT Fig. 23 Page 20 operation 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. BUCKING LOGS UNDER STRESS See Figure 28. Make the first bucking cut 1/3 of the way through the log and finish with a 2/3 cut on the opposite side. As you cut the log, it will tend to bend. The saw can become pinched or hung in the log if you make the first cut deeper than 1/3 of the diameter of the log. Give special attention to logs under stress to prevent the bar and chain from pinching. OVERBUCKING See Figure 29. Begin on the top side of the log with the bottom of the saw against the log; exert light pressure downward. Note that the saw will tend to pull away from you. WEDGE Fig. 27 LOAD FINISHING CUT 1st CUT 1/3 Dia Log Supported at One End Log Supported at Both Ends FINISHING CUT 1st CUT 1/3 Dia LOAD Fig. 28 Overbucking Fig. 29 Page 21 UNDERBUCKING See Figure 30. Begin on the under side of the log with the top of the saw against the log; exert light pressure upward. During underbucking, the saw will tend to push back at you. Be prepared for this reaction and hold the saw firmly to maintain control. LIMBING AND PRUNING See Figures 31 - 32. n Work slowly, keeping both hands on the saw with a firm grip. Maintain secure footing and balance. ¦n Keep the tree between you and the chain while limbing. n Do not cut from a ladder. This is extremely dangerous. Leave this operation for professionals. ¦n Do not cut above chest height. A saw held higher than chest height is difficult to control against kickback. WARNING: Never climb into a tree to limb or prune. Do not stand on ladders, platforms, a log, or in any position which can cause you to lose your balance or control of the saw. ¦n When pruning trees it is important not to make the flush cut next to the main limb or trunk until you have cut off the limb further out to reduce the weight. This prevents stripping the bark from the main member. • Underbuck the branch 1/3 through for your first cut. • Overbuck the branch to drop it. • Finish by cutting smoothly and neatly against the main member so the bark will grow back to seal the wound. WARNING: If the limbs to be pruned are above chest height, hire a professional to perform the pruning. CUTTING SPRINGPOLES See Figure 33. A springpole is any log, branch, rooted stump, or sapling which is bent under tension by other wood so that it springs back if the wood holding it is cut or removed. On a fallen tree, a rooted stump has a high potential of springing back to the upright position during the bucking cut to separate the log from the stump. Watch out for springpoles — they are dangerous. WARNING: Springpoles are dangerous and could strike the operator, causing the operator to lose control of the chain saw. T...
