OPERATING INSTRUCTIONS Felling trees Hazardous conditions WARNING Do not fell trees during periods of high wind or heavy precipitation. Wait until the hazardous weather has ended. When felling a tree, it is important that you heed the following warnings to prevent possible serious injury. • Do not cut down trees having an extreme lean or large trees with rotten limbs, loose bark, or hollow trunks. Have these trees pushed or dragged down with heavy equipment, then cut them up.
OPERATING INSTRUCTIONS • • • • Consider the force and direction of the wind, the lean and balance of the tree, and the location of large tree will fall. Do not try to fell a tree along a line different from its natural line of fall. Remove dirt, stones, loose bark, nails, staples, and wire from the tree where felling cuts are to be made. Notched Undercut. Cut a notch about 1/3 the diameter of the trunk on the side of the tree. Make the notch cuts so they intersect at a right angle to the line of fall.
OPERATING INSTRUCTIONS Bucking Bucking is the term used for cutting a fallen tree to the desired log length. • Always make sure your footing is secure and your weight is distributed evenly on both feet. • Cut only one log at a time. • Support small logs on a saw horse or another log while bucking. • Keep a clear cutting area. Make sure that no objects can contact the guide bar nose and chain during cutting as this can cause kickback. Refer to Kickback earlier in this manual.
OPERATING INSTRUCTIONS Overbucking 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. Avoid cutting earth overbucking Underbucking Begin on the under side of the log with the top of the saw against the log; exert light pressure upward. During under bucking, the saw will tend to push back at you. Be maintain control. Push underbucking Limbing Limbing is removing branches from a fallen tree.
