4. For safe operation
1. Never operate a chain saw when you are
fatigued, ill, or upset, or under the
influence of medication that may make
you drowsy, or if you are under the
influence of alcohol or drugs.
8. Before you start the engine, make sure
the saw chain is not contacting anything.
9. Always carry the chain saw with the
engine stopped, the guide bar and saw
chain to the rear, and the muffler away
from your body.
2. Use safety footwear, snug fitting clothing
and eye, hearing and head protection
devices.
10. Always inspect the chain saw before
each use for worn, Ioose, or changed
parts. Never operate a chain saw that is
damaged, improperly adjusted, or is not
completely and securely assembled. Be
sure that the saw chain stops moving
when the throttle control trigger is
released.
3. Always use caution when handling fuel.
Wipe up all spills and then move the
chain saw at least ten(10) feet(three(3)
m) from the fueling point before starting
the engine.
3a) Eliminate all sources of sparks or
flame (ie. smoking, open flames, or
work that can cause sparks) in the
areas where fuel is mixed, poured, or
stored.
11. All chain saw service, other than the
items listed in the Operator’s Manual,
should be performed by competent chain
saw service personnel. (e.g., if improper
tools are used to remove the flywheel, or
if an improper tool is used to hold the
flywheel in order to remove the clutch,
structural damage to the flywheel could
occur which could subsequently cause
the flywheel to disintegrate).
3b) Do not smoke while handling fuel or
while operating the chain saw.
4. Do not allow other persons to be near
the chain saw when starting the engine
or cutting a wood. Keep bystanders and
animals out of the work area. Children,
pets, and bystanders should be a
minimum of thirty(30) feet away when
you start or operate the chain saw.
12. Always shut off the engine before setting
it down.
13. Use extreme caution when cutting small
size brush and saplings because slender
material may catch the saw chain and be
whipped toward you or pull you off
balance.
5. Never start cutting until you have a clear
work area, secure footing, and planned
retreat path from the falling tree.
6. Always hold the chain saw firmly with
both hands when the engine is running.
Use a firm grip with thumb and fingers
encircling the chain saw handles.
14. When cutting a limb that is under
tension, be alert for spring back so that
you will not be struck when the tension in
the wood fibers is released.
7. Keep all parts of your body away from
the saw chain when the engine is
running.
15. Keep the handles dry, clean and free of
oil or fuel mixture.

4. For safe operation
16. Operate the chain saw only in well
ventilated areas. Never start or run the
engine inside a closed room or building.
Exhaust fumes contain dangerous
carbon monoxide.
19. When transporting your chain saw, make
sure the appropriate guide bar scabbard
is in place.
20. This chain saw is equipped with a spark
arrester built-in muffler. Periodically
check the arrester to keep it in good
order.
17. Do not operate a chain saw in a tree
unless specially trained to do so.
18. Guard against kickback. Kickback is the
upward motion of the guide bar which
occurs when the saw chain at the nose
of the guide bar contacts an object.
Kickback can lead to dangerous loss of
control of the chain saw.
KICKBACK SAFETY PRECAUTIONS FOR
CHAIN SAW USERS
WARNING
● Kickback may occur when the nose or tip of the guide bar touches an object, or when the
wood closes in and pinches the saw chain in the cut. Tip contact in some cases may
cause a lightning fast reverse reaction, kicking the guide bar up and back towards the
operator. Pinching the saw chain along the top of the guide bar may push the guide bar
rapidly back towards the operator. Either of these reactions may cause you to lose
control of the saw which could result in serious personal injury.
● Do not rely exclusively on the safety devices built into your saw. As a chain saw user you
should take several steps to keep cutting jobs free from accident or injury.
(1) With a basic understanding of kickback you can reduce or eliminate the element of
surprise. Sudden surprise contributes to accidents.
(2) Keep a good grip on the saw with both hands, the right hand on the rear handle, and
the left hand on the front handle, when the engine is running. Use a firm grip with
thumbs and fingers encircling the chain saw handles. A firm grip will help you reduce
kickback and maintain control of the saw. Don’t let go.
(3) Make certain that the area in which you’re cutting is free from obstructions. Do not let
the nose of the guide bar contact a log, branch, or any other obstruction which could
be hit while you are operating the saw.
(4) Cut at high engine speeds.
(5) Do not overreach or cut above shoulder height.
(6) Follow manufacturers sharpening and maintenance instructions for saw chain.
(7) Only use replacement bars and chains specified by the manufacturer or the
equivalent.

to first practice sawing easy logs. This also
helps you get accustomed to your unit.
• Always follow the safety regulations. The
chain saw must only be used for cutting
wood. It is forbidden to cut other types of
material. Vibrations and kickback vary with
different materials and the requirements of
the safety regulations would not be
respected. Do not use the chain saw as a
lever for lifting, moving or splitting objects.
Do not lock it over fixed stands. It is
forbidden to hitch tools or applications to the
P.t.o. that are not 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.
■ GUARD AGAINST KICKBACK (F20)
F20
• 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 the throttle for I -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.

jusqu’à celui-ci.
