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, page 11). 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, page 11). 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. Direction of Fall 3rd Cut Hinge 5 cm (2 in.)

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 WARNING: Avoid kickback. Kickback can result in severe injury or death. SeeKickback, page 3 to avoid risk of kickback. WARNING: • If on slope, make sure log will not roll down hill. Secure log by using wooden stakes. Drive wooden stakes into ground on downhill side of log. Stand on uphill side of log while cutting. Log may roll after cutting. • Never try cutting through two logs at same time. This could increase the risk of kickback. • While cutting log, never hold log with your hand, leg, or foot. • While cutting log, never allow another person to hold log. • Turn off and unplug saw before moving from one place to another. CAUTION: Seek professional help if facing conditions beyond your ability. Bucking a log is cutting a log into sections. Make sure your footing is firm. Keep feet apart. Divide your weight evenly on both feet. Stand slightly to left of saw. This keeps your body from being in direct line with chain. When possible, raise log or section off ground. Do this by using limbs, logs, chocks, etc. When cutting through log, maintain control by reducing cutting pressure near end of cut. Do not relax your grip on chain saw handles. Do not let moving chain touch ground. Ground will dull moving chain. After cutting through log, release trigger to turn saw off before moving saw. Follow directions below to buck a log.
