WARNING
• Before proceeding to your job,
• Always follow the safety regula-
• It is not necessary to force the saw into the cut.
Apply only light pressure while running the en-
gine at full throttle.
• When `e 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.
• If the guide bar and saw chain becomes caught
in wood while operating it, stop the engine.
Do not pry the handle with excessive force. Use
a wedge to remove the chain instead..
■ GUARD AGAINST KICKBACK
• This saw is equipped with a chain
brake that will stop the chain in the
event of kickback if operating prop-
erly. You must check the chain brake
operation before each usage by run-
ning the saw at full the throttle for I -2
seconds and pushing the front hand

tions. The chain saw must only
be used for cutting wood. It is
forbidden to cut other types of
material. Vibrations and kick-
back vary with different materi-
als and the requirements of the
safety regulations would not be
respected. Do not use the chain
saw as a lever for lifting, mov-
ing or splitting objects. Do not
lock it over fixed stands. It is
forbidden to hitch tools or ap-
plications to the PTO other than
those specified by the manufac-
turer.
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 opera-
tion 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, inad-
equate maintenance, or incorrect
replacement of the bar or chain may
increase the risk to serious personal
injury due to kickback.
■ FELLING A TREE
Felling direction
Notch cut
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 the bending direction to prevent the
guide bar from being caught in the cut.
