WARNING
• Before proceeding to your job,
re a d t h e s e c t i o n " F o r S a f e
Operation". It is recommended
to first practice sawing easy
logs. This also helps you get
accustomed to your unit.
• Always follow the safety regu-
lations. The chain saw must
only be used for cutting wood.
It is forbidden to cut other
types of material. Vibrations
and kickback vary with differ-
ent materials and the require-
ments of the safety regulations
would not be respected. Do
not use the chain saw as a le-
ver for lifting, moving or split-
ting objects. Do not lock it over
fixed stands. It is forbidden to
hitch tools or applications to
t h e P T O o t h e r t h a n t h o s e
specified by the manufacturer.
• It is not necessary to force the
saw into the cut. Apply only
light pressure while running the
engine at full throttle.
• 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.
• If the guide bar and saw chain
becomes caught in wood while
operating it, stop the engine.
Do not pry the handle with ex-
cessive force. Use a wedge to
remove the chain instead.

■ STOPPING THE ENGINE
1. Release the throttle lever to allow the engine to idle
for a few minutes.
2. Set the switch to the "O" (STOP) position.
■ GUARD AGAINST KICKBACK
To prevent kickback, do not use the tip of the guide
bar for cutting.
■ 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 work-
ers of the danger.
