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

•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.
