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. National reg-
ulation can restrict the use. Long or continuous expo-
sure to high noise levels may cause permanent hearing
impairment. Always wear approved hearing protection.
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 the safety footwear shall have
slip-resistance protection, snug fit-
ting 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 cut-
ting. Keep bystanders and animals
out of the work area. Children, pets
and bystanders should be a minimum
of 10 m away when you start or oper-
ate the chain saw.
8. Never start cutting until you have a
clear work area, secure footing,
and a planned retreat path from the
falling 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 run-
ning.
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 damage
to the flywheel could occur which
could subsequently cause the fly-
wheel 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 toward
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 ten-
sion 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 operation.
19. Keep the handles dry, clean and free
of oil or fuel mixture.

20. Operate the chain saw only in well
ventilated areas. Never start or run
the engine inside a closed room or
building. Exhaust fumes contain dan-
gerous carbon monoxide. Warning
about the emission of lubrication oil
mist and saw dust.
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 dan-
gerous loss of control of the chain
saw.
23. When transporting your chain saw,
make sure the appropriate guide bar
cover is in place.
24. Never touch the muffer cover, guide
bar, saw chain or nut with bare hands
while the engine is in operation or im-
mediately after shutting down the
engine. Doing so could result in seri-
ous burns because of high tempera-
ture.

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
handles. A firm grip will help you re-
duce 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.
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
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 several
steps to keep cutting jobs free from
accident or injury.
(1) With a basic understanding of kick-
back you can reduce or eliminate the
WORSE EFFECTS OF VIBRATION
If you continue to use high-vibration tools these symp-
toms 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 vi-
bration).
2. Check tools before using them to make sure they
have been properly maintained and repaired to avoid
increased 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

WORKING WITH TREE SERVICE CHAIN-SAWS
FROM A ROPE AND HARNESS
This chapter sets out working practices to reduce the
risk of injury from tree service chainsaws when working
at height from a rope and harness. While it may form
the basis of guidance and training literature, it should
not be regarded as a substitute for formal training.
General requirements working at height
Operators of tree service chainsaws working at height
from a rope and harness should never work alone. A
competent ground worker trained in appropriate emer-
gency procedures should assist them.
Operators of tree service chainsaws for this work should
be trained in general safe climbing and work position-
ing techniques and shall properly equipped with har-
nesses, ropes, strops, karabiners and other equipment
for maintaining secure and safe working positions for
both themselves and the saw.
Preparing to use the saw in the tree
The chainsaw should checked, fuelled, started and
warmed up by the ground worker before it is sent up to
the operator in the tree. The chainsaw should be fitted
with a suitable strop for attaching to the operator’s har-
ness:
a) secure the strop around the attachment point on the
rear of the saw (A);
(A)
b) provide suitable karabiners to allow indirect (i.e. via
the strop) and direct attachment (i.e. at the attach-
ment point on the saw) of saw to the operators har-
ness;
c) ensure the saw is securely attached when it is being
sent up to the operator;
d) ensure the saw it secured to the harness before it is
disconnected from the means of ascent.
The saw should only be attached to the recommended
attachment points on the harness. These may be at
mid-point (front or rear) or at the sides. Where possible
attaching the saw to centre rear mid-point will keep it
clear of climbing lines and support its weight centrally
down the operator's spine.
When moving the saw from any attachment point to an-
other, operators should ensure it is secured in the new
position before releasing it from the previous attachment
point.
Using the chainsaw in the tree
An analysis of accidents with these saws during tree
service operations shows the primary cause as being
inappropriate one-handed use of the saw. In the vast
majority of accidents, operators fail to adopt a secure
work position witch allows them to hold both handles of
the saw. This results in an increased risk of injury due
to:
•nothavingarmgriponthesawifitkicksback;
• alackofcontrolofthesawsuchthatitismoreliable
to contact climbing lines and operators body (par-
ticularly the left hand and arm)
• losingcontrolfrominsecureworkpositionresultingin
contact with the saw (unexpected movement during
operation of the saw)
Securing the work position for two-handed use
To allow the operator to hold the saw with both hands,
they should as general rule, aim for secure work posi-
tion where they are operating the saw at:
• hiplevelwhencuttinghorizontalsections;
• solarplexuslevelwhencuttingverticalsections.
Where the operator is working close into vertical stems
with a low lateral forces on their work position, then a
good footing may be all that is needed to maintain a
secure work position. However as operators move away
from the stem, they will need to take steps to remove or
counteract the increasing lateral forces by, for example,
a re-direct of the main line via a supplementary anchor
point or using an adjustable strop direct from the har-
ness to a supplementary anchor point.
G2200T
GB-6
*01_G2200T__GB_CS5_五.indd 6 16/10/04 13:17

Gaining a good footing at the working position can be
assisted by use of a temporary foot stirrup created from
an endless sling.
Starting the saw in the tree
When starting the saw in the tree, the operator should:
a) apply the chain brake before starting;
b) hold saw on either the left or right of the body when
starting:
1) on the left side hold the saw with either the left hand
on the front handle or the right hand on the rear
handle and thrust the saw away from the body while
holding the pull starter cord in the other hand;
2) on the right side, hold the saw with the right hand on
either handle and thrust the saw away from the body
while holding the pull starter cord in the left hand.
The chain brake should always be engaged before low-
ering a running saw onto its strop.
Operators should always check the saw has sufficient
fuel before undertaking critical cuts.
One-hand use of the chainsaw
Operators should not use tree service chainsaws one-
handed in place of unstable work positioning or in pref-
erence to a handsaw when cutting small diameter wood
at the branch tips.
Tree service chainsaws should only be used one-handed
where:
• theoperatorcannotgainaworkpositionenablingtwo-
handed use; and
• theyneedtosupporttheirworkingpositionwithone
hand; and
• thesawisbeingusedatfullstretch,atrightanglesto
and out of line with the operator’s body.
Operators should never:
• cutwiththekickbackzoneatthetipofthechainsaw
guide bar
• ‘holdandcut’sections
• attempttocatchfallingsections.
Freeing a trapped saw
If the saw should become trapped during cutting, op-
erators should:
• switchoffthesawandattachitsecurelytothetree
inboard (i.e. towards the truck side) of the cut or to a
separate tool line;
• pullthesawfromthekerfwhilstliftingthebranchas
necessary;
• ifnecessary,useahandsaworsecondchainsawto
release the trapped saw by cutting a minimum of 30
cm away from the trapped saw.
Whether a handsaw or a chainsaw is used to free a stuck
saw, the release cuts should always be outboard (to-
ward the tips of the branch), in order to prevent the saw
being taken with the section and further complicating
the situation.

WARNING
• Gasoline is very flammable. Avoid smo
king or bringing
any flame or sparks near fuel. Make sure to stop the en-
gine and allow it cool before refueling the unit. Select
outdoor bare ground for fueling and move at least 3 m
(10 ft) away from the fueling point before starting the
engine.

occur.
• Unleadedgasolineisrecommendedtoreducethecontami-
nation of the air for the sake of your health and the environ-
ment.
• Poor quality gasolines or oils may damage sealing rings,

■ HOW TO MIX FUEL
WARNING
•Payattentiontoagitation.
1. Measure out the quantities of gasoline and oil to be mixed.
2. Put some of the gasoline into a clean, approved fuel con-
tainer.
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 de-
pending on oil ingredients, sufficient agitation is neces-
sary for the engine to last long. Be careful that, if the agita-
tion 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 dust-
less place.
2. Put fuel into the fuel tank to 80% of the full capacity.
3. Fasten the fuel cap securely and wipe up any fuel spillage
around the unit.
WARNING
1. Select bare ground for fueling.
2. Move at least 10 feet (3 meters) away from the fueling point
before starting the engine.
3. Stop the engine before refueling the unit. At that time, be
sure to sufficiently agitate the mixed gasoline in the con-
tainer.
■ FOR YOUR ENGINE LIFE, AVOID:
1. FUEL WITH NO OIL (RAW GASOLINE) – It will cause se-
vere damage to the internal engine parts very quickly.
2. GASOHOL – It can cause deterioration of rubber and/or
plastic parts and disruption of engine lubrication.
3. OIL FOR 4-STROKE ENGINE USE – It can cause spark
plug fouling, exhaust port blocking, or piston ring sticking.
4. Mixed fuels which have been left unused for a period
of one month or more may clog the carburetor and result
in the engine failing to operate properly.
5. In the case of storing the product for a long period of time,
clean the fuel tank after rendering it empty. Next, activate
the engine and empty the carburetor of the composite fuel.
6. In the case of scrapping the used mixed oil container, scrap
it only at an authorized repository site.
NOTE
As for details of quality assurance, read the description in the
section Limited Warranty carefully. Moreover, normal wear and
change in product with no functional influence are not covered
by the warranty. Also, be careful that, if the usage in the in-
struction manual is not observed as to the mixed gasoline, etc.
described therein, it may not be covered by the warranty.
■ SUPPLYING CHAIN OIL
WARNING
Running the equipment for long hours with its chain oil run out
will accelerate the wear and tear of the chain and guide bar,
possibly resulting further in a chain cut and even in a fatal
accident leading to death.
1. For chain oil, use a type that is sufficiently viscous and
adequately lubricating under the summer-use conditions
and another type that shows similar performance under
the winter-use conditions.
2. TheuseofZonoahgenuinechainoilisrecommendedto
make your chain saws last as long as possible. If no genu-
ine chain oil is available, please use commercially avail-
able chain oil, which is commonly used.
CAUTION
Using waste oil, recycled oil, or anything similar causes a break-
down and also proves harmful to the human body and envi-
ronment. Please do not under any circumstances use any such
material.
IMPORTANT
Use chain oil of vegetable origin. Before storing it for a long
period, remove the chain oil from the blade and chain groove
and clean them. If not, the chain may become rusted. Chain
rust will cause the chain to become rigid or to become viscous
at the tip.

6. When engine has started, turn the choke knob to
the open positior and the pull the starter again to
the engine.
7. Allow the engine to warm up with the throttle lever
pulled slightly.
WARNING
Keep clear of the saw chain as it will start rotating
upon starting of engine.
■ CHECKING THE OIL SUPPLY
WARNING
Make sure to set up the bar and the chain when
checking the oil supply.
If not, the rotating parts may be exposed. It is very
dangerous.
After starting the engine, run the chain at medium speed
and see if chain oil is scattered off as shown in the fig-

cutting attachment when the machine is being
transported or in storage, in order to prevent acci-
dent contact with the sharp chain. Even a non-
moving chain can cause serious cuts to yourself or
persons you bump into with an exposed chain.
• Securethemachineduringtransport.
■ LONG-TERM STORAGE
Empty the fuel/oil tanks in a well ventilated area. Store
the fuel in approved cans in a safe place. Fit the guide
bar cover. Clean the machine. See instructions under
the heading Maintenance schedule.
Ensure the machine is cleaned and that a complete
service is carried out before long-term storage.

2. Start the engine and allow it to warm up in low speed
for a few minutes.
3. Turn the idle adjusting screw (T) counterclockwise
so that the saw chain does not turn. If the idling
speed is too slow, turn the screw clockwise.
4. Make a test cut and adjust the H needle for best
cutting power, not for maximum speed.
■ CHAIN BRAKE
The chain brake is a device which stops the chain in-
stantaneously if the chain saw recoils due to kickback.
Normally, the brake is activated automatically by iner-
tial force. It can also be activated manually by pushing
the brake lever (left-hand guard) down toward the front.
When the brake operates, a yellow cone pops up from
the base of the brake lever.
Releasing the Brake
Pull the brake lever up toward the left-hand handle until
it clicks into place.
WARNING
• Whenthebrakeoperates,releasethethrottlelever
to slow down the engine speed. Continuous opera-
tion with the brake engaged will generate heat from
the clutch and may cause trouble.
• Atmachineinspectionpriortoeachjob,checkthe
operating condition of the brake following the
steps.

■ FELLING A TREE
Notch cut Felling cut
Felling direction
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.

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.
• Before proceeding to your job,
read the section “For Safe
Operation”. It is recommended
to first practice sawing Small
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
the PTO other than those
specified by the manufacturer.

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 or-
der to maintain the kickback
safety level of this saw. Removal
of the safety devices, inadequate
