Felling a tree
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.
CAUTION
When you fell a tree, be sure to warn your
neighboring workers of the danger.
Logging and limbing
• 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.
A log lying on the ground (Log 1)

Cutting a pillowed log (Log 2)

using the rear handle. Push the front handle
in the direction of cutting line. The spiked
bumper must be remaining set for further
saw guiding if necessary.

thick branches can ensure your safety and
decrease the working strength and vibration
level.
