Felling a tree
(F19)
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.
WARNING
When you fell a tree, be sure to warn your
neighboring workers of the danger.
(1) Notch cut
(2) Felling cut
(3) Felling direction Bucking and Limbing
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.
When the saw chain is caught in the cut, do
not attempt to pull it out by force, but use a
wedge or a lever to open the way.
Guardagainst kickback
This saw is equipped with a chain brake that
will stop the chain in the event of kickback
if operating properly. You must check the chain
brake operation before each usage by
running the saw at full throttle for 1-2 seconds
and pushing the front hand guard
forward.
The chain should stop immediately with the
engine at full speed, if the chain is slow to
stop or does not stop, replace the brake band
and clutch drum before use.
It is extremely important that the chain brake
be checked for proper operation before
each use and that the chain be sharp in
order to maintain the kickback safety level
of this saw. Removal of the safety devices,
inadequate maintenance, or incorrect
replacement of the bar or chain may increase
the risk of serious personal injury due to
kickback.
