1. For safe operation
WARNING
This chainsaw has been especially designed for tree
maintenance and should therefore only be used by
trained operators when working on trees.
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.
2. Use safety footwear, snug fitting
clothing and eye, hearing and head
protection devices.
Use the vibration-proof glove.
3. Keep the saw chain sharp and the
saw, including the AV system, well
maintained. A dull chain will increase
cutting time, and pressing a dull
chain through wood will increase the
vibrations transmitted to your hands.
A saw with loose components or with
damaged or worn AV buffers will also
tend to have higher vibration levels.
4. Always use caution when handling
fuel. Wipe up all spills and then move
the chain saw at least 3 m from the
fueling point before starting the en-
gine.
5. Eliminate all sources of sparks or
flame (i.e. smoking, open flames, or
work that can cause sparks) in the
areas where fuel is mixed, poured,
or stored.
6. Do not smoke while handling fuel or
while operating the chain saw.
7. Do not allow other persons to be
near the chain saw when starting or
cutting. Keep bystanders and ani-
mals out of the work area. Children,
pets and bystanders should be a
minimum of 10 m away when you
start or operate the chain saw.
8. Never start cutting until you have a
clear work area, secure footing, and
a planned retreat path from the fall-
ing tree.
9. Always hold the chain saw firmly with
both hands when the engine is run-
ning. Use a firm grip with thumb and
fingers encircling the chain saw
handles.
10. Keep all parts of your body away
from the saw chain when the engine
is running.
11. Before you start the engine, make
sure the saw chain is not contacting
anything.
12. 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.
13. Always inspect the chain saw before
each use for worn, Ioose, or dam-
aged 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.
14. All chain saw service, other than the
items listed in the Owner’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 dam-
age to the flywheel could occur
which could subsequently cause the
flywheel to disintegrate.)
15. Always shut off the engine before
setting it down.
16. Use extreme caution when cutting
small size brush and saplings be-
cause slender material may catch
the saw chain and be whipped to-
ward you or pull you off balance.
17. When cutting a limb that is under ten-
sion, be alert for spring- back so that
you will not be struck when the tension
in the wood fibers is released.
18. Never cut in high wind, bad weather,
when visibility is poor or in very high
or low temperatures. Always check
the tree for dead branches which
could fall during the felling opera-
tion.
19. Keep the handles dry, clean and free
of oil or fuel mixture.

GB-4
G6200
20. Operate the chain saw only in well
ventilated areas. Never start or run
the engine inside a closed room or
building and potentially explosive
atmosphere. Exhaust fumes contain
dangerous carbon monoxide.
21. Do not operate the chain saw in a tree
unless specially trained to do so.
22. 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.
23. When transporting your chain saw,
make sure the appropriate guide bar
scabbard is in place.
24. Never touch the cover, guide bar, saw
chain or nut with bare hands while
the engine is in operation or immedi-
ately after shutting down the engine.
Doing so could result in serious burns
because of high temperature.
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
alightningfastreversereaction,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 to-
wards the operator. Either of these
reactions may cause you to Iose
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 sev-
eral steps to keep cutting jobs free
from accident or injury.
(1) With a basic understanding of kick-
back 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 fin-
gers encircling the chain saw han-
dles. A firm grip will help you reduce
kickback and maintain control of the
saw.
(3) Make certain that the area in which
you are cutting is free from obstruc-
tions. 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 shoul-
der height.
(6) Follow the manufacturer’s sharpening
and maintenance instructions for the
saw chain.
(7) Only use replacement bars and
chains specified by the manufacturer
or the equivalent.

WORSE EFFECTS OF VIBRATION
If you continue to use high-vibration tools these
symptoms will probably get worse, for example:
• thenumbnessinyourhandscouldbecomeperma-
nent and you won’t be able to feel things at all;
• youwillhavedifcultypickingupsmallobjectssuch
as screws or nails;
• thevibrationwhitengercouldhappenmorefre-
quently and affect more of your fingers.
FOR PROTECTING YOUR BODY FROM VIBRATION
Please observe the following matter, in order to
protect the health of your body.
1. Always use the right tool for each job (to do the job
more quickly and expose you to less hand-arm
vibration).
2. Check tools before using them to make sure they have
been properly maintained and repaired to avoid in-
creased vibration caused by faults or general wear.
3. Make sure cutting tools are kept sharp so that they
remain efficient.
4. Reduce the amount of time you use a tool in one
go, by doing other jobs in between.
5. Avoid gripping or forcing a tool or workpiece more
than you have to.
6. Store tools so that they do not have very cold
handles when next used.
7. Encourage good blood circulation by:
• keeping warm and dry (when necessary, wear
gloves, a hat, waterproofs and use heating pads if
available);
• giving up or cutting down on smoking because
smoking reduces blood flow; and massaging and
exercising your fingers

mixed.
2. Put some of the gasoline into a clean, approved fuel
container.
3. Pour in all of the oil and agitate well.
4. Pour in the rest of gasoline and agitate again for at least
one minute. As some oils may be difficult to agitate depend-
ing on oil ingredients, sufficient agitation is necessary for
the engine to last long. Be careful that, if the agitation is
insufficient, there is an increased danger of early piston
seizing due to abnormally lean mixture.
5. Put a clear indication on the outside of the container to avoid
mixing up with gasoline or other containers.
6. Indicate the contents on outside of container for easy iden-
tification.
■FUELING THE UNIT
1. Untwist and remove the fuel cap. Rest the cap on a
