2.While clearing the area around the tree, arrange a good foothold and retreat path.

3.Make a notch cut one-third of the way into the tree on the felling side.

4.Make a felling cut from the opposite side of the notch and at a level slightly higher than the bottom of the notch.

WARNING

Always ensure your foothold. Do not stand on the log.

Be alert to the rolling over of a cut log. Especially when working on a slope, stand on the uphill side of the log.

Follow the instructions in "For Safe Operation" to avoid kickback of the saw.

Before starting work, check the direction of bending force inside the log to be cut. Always finish cutting from the opposite side of bending direction to prevent the guide bar from being caught in the cut.
