KICKBACK SAFETY FEATURES WARNING: WE DO NOT REPRESENT AND YOU SHOULD NOT ASSUME THAT THE CHAIN BRAKE WILL PROTECT YOU IN THE EVENT OF A KICKBACK. Kickback is a lightning fast action which throws the bar and rotating chain back and up toward the operator. Kickback can be caused by allowing contact of the bar tip in the danger zone with any hard object. Kickback can also be caused by pinching the saw chain along the top of the guide bar. This action may push the guide bar rapidly back toward the operator.

Plan a clear retreat path Direction of Fall 45_ FELLING LARGE TREES (6 inches (15 cm) in diameter or larger) The notch method is used to fell large trees.

NOTE: If the tree has large buttress roots, remove them before making the notch.
1st Cut Overcutting Undercutting 2nd Cut Undercutting involves cutting on the underside of the log with top of saw against the log. When undercutting use light upward pressure. Hold saw firmly and maintain control. The saw will tend to push back toward you. Using a support stand 2nd Cut WARNING: Never turn saw upside down to undercut. The saw cannot be controlled in this position. Always make your first cut on the compression side of the log.
S Remove larger, supporting branches with the cutting techniques described in BUCKING WITHOUT A SUPPORT. S Always use an overcut to cut small and freely hanging limbs. Undercutting could cause limbs to fall and pinch the saw. S Next make a 2nd cut all the way through the limb. Then cut a third overcut leaving a 1 to 2 inch (2.5 to 5 cm) collar from the truck of the tree. PRUNING Second cut Third cut WARNING: Limit pruning to limbs shoulder height or below.
