not contact spark plug to prevent accidental
starting when setting up, transporting, ad-
justing or making repairs except carburetor
adjustments.
Because a chain saw is a high-speed wood-
cutting tool, special safety precautions must
be observed to reduce the risk of accidents.
Careless or improper use of this tool can
cause serious injury.
PLAN AHEAD
SRead this manual carefully until you com-
pletely understand and can follow all safe-
ty rules, precautions, and operating in-
structions before attempting to use the

approved safety hard hat;and soundbarri-
ers (ear plugs or mufflers) to protect your
hearing. Regular users should have hear-
ing checked regularly as chain saw noise
can damage hearing. Secure hair above
shoulder length.
SKeep all parts of your body away from the
chain when the engine is running.
SKeep children, bystanders, and animals a
minimum of 10 Meters away from the work
area. Do not allow other people or animals
to be near the chain saw when starting or
operating the chain saw.
SDo not handle or operate a chain saw when
you are fatigued, ill, or upset, or if you have
taken alcohol, drugs, or medication. You
must be in good physical condition and men-
tally alert. Chain saw work is strenuous. If
you have any condition that might be aggra-
vated by strenuous work, check with your
doctor before operating a chain saw.
SCarefully plan your sawing operation in ad-
vance. Do not start cutting until you have a
clear work area, secure footing, and, if you
are felling trees, a planned retreat path.
OPERATE YOUR SAW SAFELY
SDo not operate a chain saw with one hand.
Serious injury to the operator, helpers, by-
standers or any combination of these per-
sons may result from one-handed opera-
tion. A chain saw is intended for
two-handed use.
SOperate the chain saw only in a well-venti-
lated outdoor area.
SDo not operate saw from a ladder or in a
tree, unless you are specifically trained to
do so.
SMake sure the chain will not make contact
with any object while starting the engine.
Never try to start the saw when the guide
bar is in a cut.
SDo not put pressure on the saw at the end of
the cut. Applying pressure can cause you to
lose control when the cut is completed.
SStop the engine before setting the saw
down.

4
SDo not operate a chain saw that is dam-
aged, improperly adjusted, or not com-
pletely and securely assembled. Always
replace bar, chain, hand guard, or chain
brake immediately if it becomes damaged,
broken or is otherwise removed.
SWith the engine stopped, hand carry the
chain saw with the muffler away from your
body, and the guide bar and chain to the
rear, preferably covered with a scabbard.
MAINTAIN YOUR SAW IN GOOD
WORKING ORDER
SHave all chain saw service performed by a
qualified service dealer with the exception of
the items listed in the maintenance section of
this manual. For example, if improper tools
are used to remove or hold the flywheel
when servicing the clutch, structural damage
to the flywheel can occur and cause the fly-
wheel to burst.
SMake certain the saw chain stops moving
when the throttle trigger is released. For
correction, refer to CARBURETOR AD-
JUSTMENTS.
SNever modify your saw in any way. Use
only attachments supplied or specifically
recommended by the manufacturer.
SKeep the handles dry, clean, and free of oil
or fuel mixture.
SKeep fuel and oil caps, screws, and fas-
teners securely tightened.
SUse only PartnerRaccessories and re-
placement parts as recommended.
HANDLE FUEL WITH CAUTION
SDo not smoke while handling fuel or while
operating the saw.
SEliminate all sources of sparks or flame in
the areas where fuel is mixed or poured.
There should be no smoking, open flames,
or work that could cause sparks. Allow en-
gine to cool before refueling.
SMix and pour fuel in an outdoor area on bare
ground; store fuel in a cool, dry, well venti-
lated place; and use an approved, marked
container for all fuel purposes. Wipe up all
fuel spills before starting saw.
SMove at least 10 feet (3 meters) from fuel-
ing site before starting engine.
STurn the engine off and let saw cool in a
non-combustible area, not on dry leaves,
straw, paper, etc. Slowly remove fuel cap
and refuel unit.
SStore the unit and fuel in an area where fuel
vapors cannot reach sparks or open
flames from water heaters, electric motors
or switches, furnaces, etc.
KICKBACK
WARNING:Avoid kickback which
can result in serious injury. Kickback is the
backward, upward or sudden forward motion
of the guide bar occurring when the saw
chain near the upper tip of the guide barcon-
tacts any object such as a log or branch, or
when the wood closes in and pinches the
saw chain in the cut. Contacting a foreign ob-
ject in the wood can also result in loss of
chain saw control.
SRotational Kickback can occur when the
moving chain contacts an object at the up-
per tip of the guide bar. This contact can
cause the chain to dig into the object,
which stops the chain for an instant. The
result is a lightning fast, reverse reaction
which kicks the guide bar up and back to-
ward the operator.
SPinch-Kickback can occur when the the
wood closes in and pinches the moving
saw chain in the cut along the top of the
guide bar and the saw chain is suddenly
stopped. This sudden stopping of the
chain results in a reversal of the chain
force used to cut wood and causes the
saw to move in the opposite direction of the
chain rotation. The saw is driven straight
back toward the operator.
SPull-In can occur when the moving chain
contacts a foreign object in the wood in the
cut along the bottom of the guide bar and the
saw chain is suddenly stopped. This sudden
stopping pulls the saw forward and away
from the operator and could easily cause the
operator to lose control of the saw.
Avoid Pinch--Kickback:
SBe extremely aware of situations or obstruc-
tions that can cause material to pinch the top
of or otherwise stop the chain.
SDo not cut more than one log at a time.
SDo not twist the saw as the bar is with-
drawn from an undercut when bucking.
Avoid Pull--In:
SAlways begin cutting with the engine at full
speed and the saw housing against wood.
SUse wedges made of plastic or wood.
Never use metal to hold the cut open.

Working Area
REDUCETHECHANCEOF
KICKBACK
SRecognize that kickback can happen.
With a basic understanding of kickback,
you can reduce the element of surprise
which contributes to accidents.
SNever let the moving chain contact any ob-
ject at the tip of the guide bar.
SKeep the working area free from obstruc-
tions such as other trees, branches, rocks,
fences, stumps, etc. Eliminate or avoid any
obstruction that your saw chain could hit
while you are cutting through a particular log
or branch.
SKeep your saw chain sharp and properly
tensioned. A loose or dull chain can increase
the chance of kickback occurring. Follow
manufacturer’s chain sharpening and main-
tenance instructions. Check tension at regu-

5
lar intervals with the engine stopped, never
with the engine running. Make sure the bar
clamp nuts are securely tightened after ten-
sioning the chain.
SBegin and continue cutting at full speed. If
the chain is moving at a slower speed, there
is greater chance of kickback occurring.
SCut one log at a time.
SUse extreme caution when re-entering a
previous cut.
SDo not attempt cuts starting with the tip of
the bar (plunge cuts).
SWatch for shifting logs or other forces that
could close a cut and pinch or fall into chain.
SUse the Reduced--Kickback Guide Bar
and Low--Kickback Chain specified for
your saw.
MAINTAIN CONTROL
Never reverse
hand positions
Stand to the left of
the saw
Thumb on underside of
handlebar
Elbow locked
SKeep a good, firm grip on the saw with both
hands when the engine is running and
don’t let go. A firm grip will help you reduce
kickback and maintain control of the saw.
Keep the fingers of your left hand encir-
cling and your left thumb under the front
handlebar. Keep your right hand complete-
ly around the rear handle whether your are
right handed or left handed. Keep your left
arm straight with the elbow locked.
SPosition your left hand on the front handle-
bar so it is in a straight line with your right
hand on the rear handle when making
bucking cuts. Never reverse right and left
hand positions for any type of cutting.
SStand with your weight evenly balanced on
both feet.
SStand slightly to the left side of the saw to
keep your body from being in a direct line
with the cutting chain.
SDo not overreach. You could be drawn or
thrown off balance and lose control of the
saw.
SDo not cut above shoulder height. It is diffi-
cult to maintain control of saw above
shoulder height.
KICKBACK SAFETY FEATURES
WARNING:The following features are
included on your saw to help reduce the hazard
of kickback; however, such features will not to-
tally eliminate this dangerous reaction. As a
chain saw user, do not rely only on safety de-
vices. You must follow all safety precautions,
instructions, and maintenance in this manual to
help avoid kickback and other forces which
can result in serious injury.
SReduced--Kickback Guide Bar, designed
with a small radius tip which reduces the
size of the kickback danger zone on the
bar tip. A Reduced--Kickback Guide Bar has
been demonstrated to significantly reduce
the number and seriousness of kickbacks.

bar.
SPosition of front and rear handlebars, de-
signed with distance between handles and
“in-line” with each other. The spread and
“in-line” position of the hands provided by
this design work together to give balance
and resistance in controlling the pivot of
the saw back toward the operator if kick-
back occurs.
WARNING:DO NOT RELY UPON
ANY OF THE DEVICES BUILT INTOYOUR
SAW. YOU SHOULD USE THE SAW
PROPERLY AND CAREFULLY TO AVOID
KICKBACK. Reduced--kickback guide bars
and low--kickback saw chains reduce the
chance and magnitude of kickback and are
recommended. Your saw has a low kick-
back chain and bar as original equipment.
Repairs on a chain brake should be made by
an authorized servicing dealer. Take your
unit to the place of purchase if purchased
from a servicing dealer, or to the nearest au-
thorized master service dealer.

STip contact in some cases may cause a light-
ning fast reverse REACTION, kicking the
guide bar up and back toward the operator.
SPinching the saw chain along the top of the
guide bar may push the guide bar rapidly
back toward the operator.
SEither of these reactions may cause you to
lose control of the saw which could result
in serious injury. Do not rely exclusively
upon the safety devices built into your saw.
CHAIN BRAKE
SChain brake, designed to stop the chain in
the event of kickback.
WARNING:Your chain saw is
equipped with a chain brake that is designed
to stop the chain immediately if you get a
kickback. The chain brake reduces the risk
of accidents, but only you can prevent them.
DO NOT ASSUME THAT THE CHAIN
BRAKE WILL PROTECT YOU IN THE
EVENT OF A KICKBACK.
SAFETY NOTICE: Exposure to
vibrations through prolonged use of gasoline
powered hand tools could cause blood
vessel or nerve damage in the fingers,
hands, and joints of people prone to
circulation disorders or abnormal swellings.
Prolonged use in cold weather has been
linked to blood vessel damage in otherwise
healthy people. If symptoms occur such as
numbness, pain, loss of strength, change in
skin color or texture, or loss of feeling in the
fingers, hands, or joints, discontinue the use
of this tool and seek medical attention. An
anti-vibrationsystemdoes not guarantee the
avoidance of these problems. Users who
operate power tools on a continual and
regular basis must monitor closely their
physical condition and the condition of this
tool.
ASSEMBLY
WARNING:Recheck each assem-
bly step if the saw is received assembled.

OPERATING YOUR UNIT
BEFORE STARTING ENGINE
WARNING:Be sure to read the fuel
information in the safety rules before you be-
gin. If you do not understand the safety rules,
do not attempt to fuel your unit. Contact an
authorized service dealer.
BAR AND CHAIN LUBRICATION
The bar and chain require continuous lubri-
cation. Lubrication is provided by the auto-
matic oiler system when the oil tank is kept
filled. Lack of oil will quickly ruin the bar and
chain. Too little oil will cause overheating
shown by smoke coming from the chain and/
or discoloration of the bar.
Only use Bar and Chain Oil for bar and chain
lubrication.
Oil Cap Fuel mix cap
FUELING ENGINE
WARNING:Remove fuel cap slowly
when refueling.
This engine is certified to operate on unleaded
gasoline. Before operation, gasoline must be
mixed with a good quality 2-cycle air-cooled
engine oil designed to be mixed at a ratio of
40:1. A 40:1 ratio is obtained by mixing 0,125
liter of oil with 5 liters of unleaded gasoline. DO
NOT USE automotive or boat oil. These oils
will cause engine damage. When mixing fuel
follow the instructions printed on the container.
Always read and follow the safety rules relating
to fuel before fueling your unit.
IMPORTANT
Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads
to separation and formation of acids during
storage. Acidic gas can damagethe fuel sys-
tem of an engine while in storage. To avoid
engine problems, empty the fuel system be-
fore storage for 30 days or longer. Drain the
gas tank, start the engine and let it run until
the fuel lines and carburetor are empty. Use
fresh fuel next season. Never use engine or
carburetor cleaner products in the fuel tank
or permanent damage may occur.
CHAIN BRAKE
Ensure chain brake is disengaged by pulling
the front hand guard back toward the front han-
dle as far as possible. The chain brake must
be disengaged before cutting with the saw.
WARNING:The chain must not
move when the engine runs at idle speed. If
the chain moves at idle speed refer to CAR-
BURETOR ADJUSTMENT within this
manual. Avoid contact with the muffler. A hot
muffler can cause serious burns.
To stop the engine, move the ON/STOP
switch to the STOP position.
To start the engine, hold the saw firmly on
the ground as illustrated below. Make sure
the chain is free to turn without contacting
any object.
Hold saw firmly while pulling starter rope.
Use only 40 --- 45 cm o
f
rope per pull.

IMPORTANT POINTS TO REMEMBER
When pulling the starter rope, do not use the full
extent of the rope as this can cause the rope to
break. Do not let starter rope snap back. Hold
the handle and let the rope rewind slowly.
For cold weather starting, start the unit at full
choke; allow the engine to warm up before
squeezing the throttle trigger.
NOTE:Do not cut material with the choke/
fast idle lever at the FULL CHOKE position.
STARTING A COLD ENGINE (or a

The engine may be flooded with too much
fuel if it has not started after 10 pulls.
Flooded engines can be cleared of excess
fuel by pushing the choke/fast idle lever in
completely (to the OFF CHOKE position)
and then following the warm engine starting
procedure listed above. Ensure the ON/
STOP switch is in the ON position. Starting
could require pulling the starter rope handle
many times depending on how badly the unit
is flooded. If engine fails to start, refer to the
TROUBLESHOOTING TABLE.
CHAIN BRAKE
WARNING:If the brake band is worn
too thin it may break when the chain brake is
triggered. With a broken brake band, the chain
brake will not stop the chain. The chain brake
should be replaced by an authorized service
dealer if any part is worn to less than 0,02″(0,5
mm) thick. Repairs on a chain brake should be
made by an authorized service dealer. Take
your unit to the place of purchase if purchased
from a servicing dealer, or to the nearest autho-
rized master service dealer.
SThis saw is equipped with a chain brake.
The brake is designed to stop the chain if
kickback occurs.
SThe inertia activated chain brake is activated
if the front hand guard is pushed forward, ei-
ther manually or by centrifugal force.
SIf the brake is already activated, it is disen-
gaged by pulling the front hand guard back
toward the front handle as far as possible.
SWhen cutting with the saw, the chain brake
must be disengaged.

Braking function control
CAUTION: The chain brake must be
checked several times daily. The engine
must be running when performing this proce-
dure. This is the only instance when the saw
should be placed on the ground with the en-
gine running.
Place the saw on firm ground. Grip the rear
handle with your right hand and the front han-
dle with your left hand. Apply full throttle by
fully depressing the throttle trigger. Activate
the chain brake by turning your left wrist
against the hand guard without releasing
your grip around the front handle. The chain
should stop immediately.

WARNING:When performing the fol-
lowing procedure, the engine must be turned
off.
Grip the rear handle with your right hand and
the front handle with your left hand. Hold the
chain saw approximately 14” (35 cm) above
a stump or other wooden surface. Release
your grip on the front handle and use the
weight of the saw to let the top of the guide
bar fall forward and contact the stump.
When the tip of the bar hits the stump, the
brake should activate.

CUTTING METHODS
IMPORTANT POINTS
SCheck chain tension before first use and af-
ter 1 minute of operation. See CHAIN TEN-
SION in the ASSEMBLY section.
SCut wood only. Do not cut metal, plastics,
masonry, non-wood building materials, etc.
SStop the saw if the chain strikes a foreign ob-
ject. Inspect the saw and repair parts as nec-
essary.
SKeep the chain out of dirt and sand. Even a
small amount of dirt will quickly dull a chain
and increase the possibility of kickback.
SPractice cutting a few small logs using the
following techniques to get the “feel” of us-
ing your saw before you begin a major
sawing operation.
SSqueeze the throttle trigger and allow the
engine to reach full speed before cutting.
SBegin cutting with the saw frame
against the log.
SKeep the engine at full speed the entire
time you are cutting.
SAllow the chain to cut for you. Exert only
light downward pressure.
SRelease the throttle trigger as soon as
the cut is completed, allowing the en-
gine to idle. If you run the saw at full
throttle without a cutting load, unneces-
sary wear can occur.
STo avoid losing control when cut is com-
plete, do not put pressure on saw at end
of cut.
SStop the engine before setting the saw down.
TREE FELLING TECHNIQUES
WARNING:Do not cut near buildings
or electrical wires if you do not know the di-
rection of tree fall, at night since you will not
be able to see well, or during bad weather
such as rain, snow, or strong winds. as fall is
unpredictable.
Carefully plan your sawing operation in ad-
vance. You need a clear area all around the
tree so you can have secure footing. Check
for broken or dead branches which can fall
on you causing serious injury.
Natural conditions that can cause a tree to
fall in a particular direction include:
SThe wind direction and speed.
SThe lean of the tree. The lean of a tree
might not be apparent due to uneven or
sloping terrain. Use a plumb or level to de-
termine the direction of tree lean.
SWeight and branches on one side.
SSurrounding trees and obstacles.
Look for decay and rot. If the trunk is rotted,
it can snap and fall toward the operator.
Make sure there is enough room for the tree to
fall. Maintain a distance of 2-1/2 tree lengths
from the nearest person or other objects. En-
gine noise can drown out a warning call.
Remove dirt, stones, loose bark, nails, sta-
ples, and wire from the tree where cuts are to
be made.
Direction of Fall
45_
Plan a clear retreat path
FELLING LARGE TREES
(15cmindiameterorlarger)
The notch method is used to fell large trees.
A notch is cut on the side of the tree in thede-
sired direction of fall. After a felling cut is
made on the opposite side of tree, the tree
will tend to fall into the notch.
NOTCH CUT AND FELLING THE
TREE
SMake notch cut by cutting the top of the
notch first. Cut through 1/3 of the diameter
of the tree. Next complete the notch by cut-
ting the bottom of the notch. See illustra-
tion. Once the notch is cut remove the
notch of wood from the tree.

SAfter removing the wood from the notch,
make the felling cut on the opposite side of
the notch. This is done by making a cut about
two inches higher than the center of the
notch. This will leave enough uncut wood
between the felling cut and the notch to form
a hinge. This hinge will help prevent the tree
from falling in the wrong direction.

NOTE:Before felling cut is complete, use
wedges to open the cut when necessary to
control the direction of fall. To avoid kickback
or chain damage, use wood or plastic
wedges, but never steel or iron wedges.
SBealerttosignsthatthetreeisreadytofall:
cracking sounds, widening of the felling cut,
or movement in the upper branches.

11
SAs tree starts to fall, stop saw, put it down,
and get away quickly on your planned re-
treat path.
SDO NOT cut down a partially fallen tree with
your saw. Be extremely cautious with par-
tially fallen trees that may be poorly sup-
ported. When a tree doesn’t fall completely,
set the saw aside and pull down the tree with
a cable winch, block and tackle, or tractor.
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a fallen
tree to the desired log length.
WARNING:Do not stand on the log
being cut. Any portion can roll causing loss of
footing and control. Do not stand downhill of
the log being cut.
Important points
SCut only one log at a time.
SCut shattered wood very carefully; sharp
pieces of wood could be flung toward oper-
ator.
SUse a sawhorse to cut small logs. Never
allow another person to hold the log while
cutting and never hold the log with your leg
or foot.
SDo not cut in an area where logs, limbs,
and roots are tangled. Drag the logs into a
clear area before cutting by pulling out ex-
posed and cleared logs first.
TYPES OF CUTTING USED FOR
BUCKING
WARNING:If saw becomes pinched
or hung in a log, don’t try to force it out. You
can lose control of the saw resulting in injury
and/or damage to the saw. Stop the saw,
drive a wedge of plastic or wood into the cut
until the saw can be removed easily. Restart
the saw and carefully reenter the cut. Do not
attempt to restart your saw when it is pinched
or hung in a log.
Turn saw OFF and use a plastic or
wooden wedge to force cut open.
Overcutting begins on the top side of the log
with the saw against the log. When overcut-
ting use light downward pressure.
Overcutting Undercutting
Undercutting involves cutting on the under-
side of the log with top of saw against the log.
When undercutting use light upward pres-
sure. Hold saw firmly and maintain control.
The saw will tend to push back toward you.
WARNING:Never turn saw upside
down to undercut. The saw cannot be con-
trolled in this position.
Second cut
First cut on pressure side of log

BUCKING WITHOUT A
SUPPORT
SOvercut through 1/3 of the diameter of the
log.
SRoll the log over and finish with a second
overcut.
SGive special attention to logs under strain
to prevent the saw from pinching. Make
the first cut on the pressure side to relieve
the stress on the log.
BUCKING USING A LOG OR SUP-
PORT STAND
SRemember your first cut is always on the
pressure side of the log.
SYour first cut should extend 1/3 of the
diameter of the log.
SFinish with your second cut.

LIMBING AND PRUNING
WARNING:Be alert for and guard
against kickback. Do not allow the moving
chain to contact any other branched or objects
at the nose of the guide bar when limbing or
pruning. Allowing such contact can result in
serious injury.
WARNING:Neverclimbintoatreeto
limb or prune. Do not stand on ladders, plat-
forms, a log, or in any position which can cause
you to lose your balance or control of the saw.
IMPORTANT POINTS
SWatch out for springpoles. Use extreme
caution when cutting small size limbs. Slen-
der material may catch the saw chain and be
whipped toward you or pull you off balance.
SBe alert for springback. Watch out for
branches that are bent or under pressure.
Avoid being struck by the branch or the saw
when the tension in the wood fibers is re-
leased.
SKeep a clear work area. Frequently clear
branches out of the way to avoid tripping
over them.
LIMBING
SAlways limb a tree after it is cut down. Only
then can limbing be done safely and prop-
erly.
SLeave the larger limbs underneath the
felled tree to support the tree as you work.
SStart at base of the felled tree and work to-
ward the top, cutting branches and limbs.
Remove small limbs with one cut.
SKeep the tree between you and the chain
as much as possible.
SRemove larger, supporting branches with
the cutting techniques described in BUCK-
ING WITHOUT A SUPPORT.
SAlways use an overcut to cut small and
freely hanging limbs. Undercutting could
cause limbs to fall and pinch saw.
PRUNING
WARNING:Limit pruning to limbs
shoulder height or below. Do not cut if
branches are higher than your shoulder. Get
a professional to do the job.
SMake your fist cut 1/3 of the way through
the bottom of the limb.
SNext make a 2nd cut all the way through
the limb. Then cut a third overcut leaving
a 1 to 2 inch collar from the trunk of the tree.

A dirty air filter decreases engine perform-
ance and increases fuel consumption and
harmful emissions. Always clean after every
5 hours of operation.
1. Clean the cover and the area around it to
keep dirt and sawdust from falling into
the carburetor chamber when the cover
is removed.
2. Remove the parts as illustrated below.
3. Wash the filter in soap and water. Rinse
in clean cool water. Air dry completely
before reinstalling.

BAR MAINTENANCE
If your saw cuts to one side, has to be forced
through the cut, or been run with an improper
amount of bar lubrication it may be neces-
sary to service your bar. A worn bar will dam-
age your chain and make cutting difficult.
After each use, ensure ON/STOP switch is
in the STOP position, then clean all sawdust
from the guide bar and sprocket hole.
To maintain guide bar:
SMove ON/STOP switch to the STOP posi-
tion.
SLoosen and remove chain brake nuts and
chain brake. Remove bar and chain from
saw.
SClean the oil holes and bar groove after each
5 hours of operation.

CHAIN SHARPENING
Chain sharpening is a complicated task that
requires special tools. We recommend that
you refer chain sharpening to a professional
chain sharpener.
CARBURETOR ADJUSTMENTS
WARNING:Thechainwillbemoving
during most of this procedure. Wear your pro-
tective equipment and observe all safety pre-
cautions. The chain must not move at idle
speed.
The carburetor has been carefully set at the
factory. Adjustments may be necessary if
you notice any of the following conditions:
SChain moves at idle. See IDLE SPEED--T
adjusting procedure.
SSaw will not idle. See IDLE SPEED--T ad-
justing procedure.
Idle Speed---T
Allow engine to idle. If the chain moves, idle
is too fast. If the engine stalls, idle is too slow.
Adjust speed until engine runs without chain
movement (idle too fast) or stalling (idle too
slow). The idle speed screw is located in the
area above the primer bulb and is labeled T.
STurn idle speed screw (T) clockwise to in-
crease engine speed.
STurn idle speed screw (T) counterclock-
wise to decrease engine speed.
STORAGE
WARNING:Stop engine and allow to

RECUL
AVERTISSEMENT:Evitez le recul
qui peut entraîner des blessures graves. Le
Recul est le mouvement vers l’arrière et/ou le
haut de la barre--guide qui se produit quand la
partie de la chaîne du haut du bout de la barre--
guide entre en contact avec tout objet, tel qu’u-
ne autre bûche ou branche, ou quand le bois
se referme et pince la chaîne de la tronçon-
neuse dans la coupe. Entre en contact avec
un objet étranger qui se trouve dans le bois
peut également avoir comme conséquence la
perte de commande à tronçonneuse.
SLe Recul de Rotation peut se produire
quand la chaîne en mouvement entre en
contact avec un objet à l’extrémité supé-
rieure du bout de la barre-guide. Ce con-
tact peut enfoncer la chaîne dans cet ob-
jet, ce qui l’arrête pour un instant. Le
résultat est une réaction ultra-rapide qui
projette la barre-guide vers le haut et l’ar-
rière, vers l’utilisateur.
SLe Pincement-Recul peut se produire
quand le bois se referme et pince la chaîne
en mouvement dans la coupe, le long du
bout de la barre--guide et la chaîne s’arrête
soudainement. Cet arrêt soudain de la
chaînecauseunrenversementdelaforce
de la chaîne utilisée pour couper le bois et
projette la tronçonneuse dans la direction in-
verse de la rotation de la chaîne. La tronçon-
neuse directement vers l’utilisateur.
SLe Rétraction peut se produire quand le
chaîne en mouvement entre en contact
avec un objet étranger qui se trouve dans
le bois, le long du bas de la barre--guide et
la chaîne s’arrête soudainement. Cet arrêt
soudain de la chaîne tire la tronçonneuse en
avant et loin de l’opérateur et pourrait facile-
ment faire détruire l’opérateur la commande
de la tronçonneuse.
Évitez le pincement--recul:
SSoyez très vigilant des situations ou des ob-
structions qui pourraient faire serrer la partie
supérieure ou autrement arrêter la chaîne.
SNe coupez pas plus d’un rondin d’une fois.
SNe tordez pas la tronçonneuse lorsque
vous l’enlevez d’une coupure ascendante
lorsque vous sectionnez des rondins.
Évitez les rétraction:
SQuand vous commencez la coupe, asu-
rez--vous toujours que le moteur est à
pleine vitese et que le chassis de la
tronçonneuse est contre le bois.
SEmployez des cales en plastique ou bois, ja-
mais en métal, pour tenir la coupure ouverte.

SMaintenez votre tronçonneuse aiguisée. La
chaîne doit toujours être bien tendue. Une
chaîne détendue ou émoussée augmente le
risque de recul. Suivez les instructions de
maintenance et d’affûtage du fabricant de la
chaîne. Contrôlez régulièrement la tension
lorsque le moteur est arrêté, jamais lorsque
le moteur fonctionne. Assurez--vous que les
écrous de l’attache sont bien serrés après
avoir tendu la chaîne.
SCommencez et continuez à couper à plein
régime. Si la chaîne tourne plus lente-
ment, le risque de recul sera plus grand.
SNe coupez qu’une bûche à la fois.
SFaites très attention lorsque vous entrez à
nouveau dans une coupe.
SN’essayez pas de couper avec le bout du
barre--guide (coupe en plongée).
SFaites attention aux bûches mobiles et au-
tres facteurs pouvant refermer la coupe et
bloquer ou tomber sur la chaîne.
SUtilisez le barre--guide et la chaîne au re-
cul réduit définis pour votre tronçonneuse.
MAINTENEZ LE CONTRÔLE

Tenez--vous de-
bout légèrement à
gauche de la
tronçonneuse.
Le pouce
en bas de
l’anse.
Placez le pouce sous le
guidon
Le coude doit être
tendu
STenez fermement la tronçonneuse à deux
mains lorsque le moteur fonctionne et ne la
lâchez pas. En maintenant fermement la
tronçonneuse, vous réduirez le risque de re-
cul et ne perdrez pas le contrôle de la
tronçonneuse. Maintenez les doigts de votre
main gauche repliés et votre pouce gauche
sous le guidon avant. Entourez complète-
ment la poignée arrière votre main droite.
Que vous soyez gaucher ou droitier ne joue
aucun rôle. Votre bras gauche doit être ten-
du et le coude bloqué.
SPlacez votre main gauche sur le guidon
avant pour qu’elle forme une ligne droite
avec votre main droite sur la poignée arrière
lorsque vous faite des tronçonnages. N’in-
versez jamais les positions des mains, quel-
le que soit la coupe.
STenez--vous sur deux pieds, le poids égale-
ment réparti.
SPositionnez--vous légèrement à gauche de
la tronçonneuse pour ne pas vous trouver
dans une ligne directe avec la chaîne de
coupe.
SNe soyez pas trop tendu. Vous risqueriez de
perdre l’équilibre et le contrôle de la tronçon-
neuse.
SNe coupez aucun objet situé au--dessus de
vos épaules. Il est difficile de contrôler la
tronçonneuse à cette hauteur.
