Always leave a hinge. The hinge guides the tree. If the trunk is completely cut through, control over the felling direction is lost. Before making the WARNING: final cut, always recheck the area for bystanders, animals or obstacles. Insert a wedge or felling lever in the cut well before the tree becomes unstable and starts to move. This will prevent the guidebar from binding in the felling cut if you have misjudged the falling direction. Make sure no bystanders have entered the range of the falling tree before you push it over. Felling Cut: 1. Use wooden or plastic wedges (G) to prevent binding the bar or chain (H) in the cut. Wedges also control felling (Fig. 10). 2. When diameter of wood being cut is greater than the bar length, make 2 cuts as shown (Fig. 11). As the felling cutWARNING: gets close to the hinge, the tree should begin to fall. When tree begins to fall, remove saw from cut, stop motor, put chain saw down, and leave area along retreat path (Fig. 8). G H Fig. 10 If felling a tree on CAUTION: sloping ground, the chain saw operator should keep on the uphill side of the terrain, as the tree is likely to roll or slide downhill after it is felled. NOTE: Direction of fall (B) is controlled by the notching cut. Before any cuts are made, consider the location of larger branches and natural lean of the tree to determine the way the tree will fall. A B Fig. 8 Do not cut down aWARNING: tree during high or changing winds or if there is a danger to property. Consult a tree professional.Do not cut down a tree if there is a danger of striking utility wires; notify the utility company before making any cuts. Normally felling consists of 2 main cutting operations, notching (C) and making the felling cut (D) (Fig. 9). Start making the upper notch cut (C) on the side of the tree facing the felling direction (E). Be sure you don t make the lower cut too deep into the trunk(Fig. 9). The notch (C) should be deep enough to create a hinge (F) of sufficient width and strength. The notch should be wide enough to direct the fall of the tree for as long as possible (Fig. 9). 11 OPERATING INSTRUCTIONS OPERATING INSTRUCTIONS Fig. 11 LIMBING Limbing a tree is the process of removing the branches from a fallen tree. Do not remove supporting limbs (A) until after the log is bucked (cut) into lengths (Fig. 12). Branches under tension should be cut from the bottom up to avoid binding the chain saw. A Fig. 12 Never cut tree limbs while standing on a tree trunk. WARNING: BUCKING Bucking is cutting a fallen log into lengths. Make sure you have a good footing and stand uphill of the log when cutting on sloping ground. If possible, the log should be supported so that the end to be cut off is not resting on the ground. If the log is supported at both ends and you must cut in the middle, make a downward cut halfway through the log and then make the undercut. This will prevent the log from pinching the bar and chain. Be careful that the chain does not cut into the ground when bucking as this causes rapid dulling of the chain. Fig. 13 12 When bucking on a slope, always stand on the uphill side. 1. Log supported along entire length: Cut from top (overbuck), being careful to avoid cutting into the ground(Fig. 13). 2. Log supported on one (1) end: First, cut from bottom(underbuck) 1/3 diameter of log to avoid splintering. Second, cut from above (overbuck) to meet first cutand avoid pinching (Fig. 14). 3. Log supported on both ends: First, overbuck 1/3 diameter of log to avoid splintering. Second, underbuck tomeet first cut and avoid pinching (Fig. 15). NOTE: The best way to hold a log while bucking is to usea sawhorse. When this is not possible, the logshould be raised and supported by the limbstumps or by using supporting logs. Be sure thelog being cut is securely supported. Fig. 14 Fig. 15 BUCKING USING A SAWHORSE For personal safety and ease of cutting, the correct position for vertical bucking is essential (Fig. 16). A. Hold the saw firmly with both hands and keep the sawto the right of your body while cutting. B. Keep the left arm as straight as possible. C. Keep weight on both feet. While the saw is cut-CAUTION: ting, be sure the chain and bar are being properly lubricated. A B Fig. 16 C MAINTENANCE AND REPAIR INSTRUCTIONS MAINTENANCE AND REPAIR INSTRUCTIONS MAINTENANCE SCHEDULE Perform these required maintenance procedures at the frequency stated in the table. These procedures should also be a part of any seasonal tune-up. To prevent serious WARNING: injury, never perform maintenance or repairs with unit running. Always service and repair a cool unit. A good preventive maintenance program of regular inspection and care will increase life and improve performance of your chain saw. This maintenance checklist is a guide for such a program. Cleaning, adjustment, and part replacement may be required, under certain conditions, at more frequent intervals than those indicated.
