FELLING A TREE (F22)
1. Decide the felling direction considering the wind,
lean of the tree, location of heavy branches, ease of
completing the task after felling and other factors.
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
When you fell a tree, be sure to warn neighboring
workers of the danger.

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.
