Continued 9 For more information, visit ® ® ELECTRIC CHAIN SAW OPERATING CHAIN SAW Continued FELLING A TREE (Cutting Down a Tree) WARNING: • Avoid kickback. Kickback can result in severe injury or death. See Kickback,page 3, to avoid risk of kickback. • Do not fell a tree without ample skill or expert help. • Keep children, animals, and bystanders away from area when felling a tree. • If two or more persons perform bucking and felling operations at the same time, provide ample distance between operations. Provide distance of at least twice the height of tree being felled. Felling is the process of cutting down a tree. Make sure your footing is firm. Keep feet apart. Divide your weight evenly on both feet. Follow directions below to fell a tree. Before Felling a Tree 1. Before felling, inspect tree. Make sure there are no dead limbs or branches that may fall on you. Study natural lean of tree, location of larger branches, and wind direction. This will help you judge which way tree will fall. 2. Clear work area around tree. 3. Plan and clear a retreat path before felling. Make retreat path opposite to planned direction of fall of tree and at 45° angle (see Figure 11). 4. Remove dirt, stones, loose bark, nails, staples, and wire from tree where you will make felling cuts. 5. Stay on uphill side when felling tree. Tree could roll or slide downhill after falling. Retreat Path Direction of Fall Tree Retreat Path 45° Figure 11 - Retreat Path From Tree Felling Procedure Felling Notch A properly placed felling notch will determine direction tree will fall. Place felling notch on side of tree in direction you want tree to fall (see Figure 12). Follow directions below to create a felling notch. 1. Make lower notch cut as close to ground as possible. Hold saw so guide bar is horizontal. Cut 1/3 the diameter of tree trunk (see Figure 12). Note:Always make this horizontal lower notch cut first. If you make this cut second, tree can pinch chain or guide bar. 2. Start upper notch cut the same distance above first cut as first cut is deep. Example:If lower notch cut is 20 centimeters deep (eight inches), start upper notch cut 20 centimeters (eight inches) above it. Cut downward at 45° angle. The upper notch cut should meet end of lower notch cut (see Figure 12). 3. Remove tree trunk wedge created by notching cuts. Felling Cut 1. Make felling cut five centimeters (two inches) higher than lower notch cut and on opposite side of tree (see Figure 12). Keep felling cut parallel to lower notch cut. 2. Cut towards notch. WARNING: Do not cut all the way through tree. Leave about five centimeters (two inches) of tree diameter uncut directly behind felling notch (see Figure 12). This uncut portion acts as a hinge. The hinge helps keep tree from twisting and falling in wrong direction. 3. As felling cut nears hinge, tree should begin to fall. Note: If needed, drive wedges into felling cut to control direction of fall. If tree settles back and pinches chain, drive wedges into felling cut to remove saw. Only use wedges made of wood, plastic, or aluminum. Never use wedge made of steel. This could cause kickback and damage to chain. 4. When tree begins to fall, quickly •remove saw from felling cut •release trigger to turn saw off • put saw down •exit area using retreat path WARNING: Be alert for falling overhead limbs. Watch your footing while exiting area.

Kickback can result in severe injury or death. SeeKickback,page 3, to avoid risk of kickback. WARNING: When cutting limb that is under tension, use extreme caution. Be alert for wood springing back. When wood tension is released, limb could spring back and strike operator causing severe injury or death. CAUTION: Seek professional help if facing conditions beyond your ability. Limbing is removing branches from a fallen tree. Make sure your footing is firm. Keep feet apart. Divide your weight evenly on both feet. Do not remove larger limbs under tree that support log off ground. Remove each limb with one cut (see Figure 13). Clear cut limbs from work area often. This will help maintain a safe work area. Make sure you start your cut where limb will not pinch saw during cutting. To avoid pinching, start cut on freely hanging limbs from above limb. Start cut on limbs under tension from under limb. If pinch occurs, turn saw off, lift limb, and remove saw. BUCKING A LOG WA...
