NOTE:
In this section, the safety features of
the chain saw and their function are explained.
For inspection and maintenance, see instructions in the CHECKING, MAINTAINI NG AND
SERVICING CHAIN SAW SAFETY EQUIPMENT section. See instructions under the
WHAT IS WHAT? section, to find where these
parts are located on your chain saw. The life
span of the machine can be reduced and the
risk of accidents can increase if machine
maintenance is not carried out correctly and
if service and/or repairs are not carried out
professionally. If you need further information, please contact your nearest service
dealer.
S Chain brake. Y ourchain saw is equipped
with a chain brake that is designed tostop
the chain from moving.
WARNING: The chain brake is de-
signed to stop the chain immediately if you
get a kickback. The chainbrake reduces the
risk of accidents, but only you can prevent
them.DONOTASSUMETHATTHECHAIN
BRAKE WILL PROTECT YOU IN THE
EVENT OF A KICKBACK.
S Throttle trigger lock--out. The throttle
lock--out is designed to prevent accidental
operation of the throttle trigger.
S Chain catcher. The chain catcher is de-
signed to catch the saw chain if it breaks.

MAINTAIN YOUR SAW IN GOOD
WORKING ORDER
S Have all chain saw service performed by a
qualified service dealer with the exception of
the items listedin themaintenance sectionof
this manual. For example, if improper tools
are used to remove or hold the flywheel
when servicing the clutch,structuraldamage
to the flywheel can occur and cause the flywheel to burst.
S Make certain the saw chain stops moving
when the throttle trigger is released. For
correction, refer to CARBURETOR ADJUSTMENTS.
S Never modify your saw in any way. Use
only attachments supplied or specifically
recommended by the manufacturer.
S Keepthe handles dry, clean, and free of oil
or fuel mixture.
S Keep fuel and oil caps, screws, and fas-
teners securely tightened.
S Use only Partner accessories and replace-
ment parts as recommended.
HANDLE FUEL WITH CAUTION
S Do not smoke while handling fuel or while
operating the saw.
S Eliminateall sources of sparks or flame in
the areas where fuel is mixed or poured.
Thereshouldbeno smoking, openflames,
orworkthatcouldcausesparks. Allowengine to cool before refueling.

or switches, furnaces, etc.
KICKBACK
WARNING: Avoid kickback which
can result in serious injury. Kickback is the
backward, upwardorsudden forwardmotion
of the guide bar occurring when the saw
chainneartheupper tip oftheguide barcontacts any object such as a log or branch, or
when the wood closes in and pinches the
saw chain inthecut. Contactinga foreignobject in the wood can also result in loss of
chain saw control.
S Rotational Kickback canoccurwhenthe
moving chain contacts an object at the upper 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 toward the operator.
S Pinch-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
sawtomove inthe oppositedirectionofthe
chain rotation. The saw is driven straight
back toward the operator.
S Pull-In can occur when the moving chain
contacts a foreign object in the wood in the
cut along the bottom of the guidebar 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:
S Be extremely aware of situations or obstruc-
tions that cancause material to pinch the top
of or otherwise stop the chain.
S Do not cut more than one log at a time.
S Do not twist the saw as the bar is with-
drawn from an undercut when bucking.
Avoid Pull--In:
S Always begin cutting withtheengineatfull
speed and the saw housing against wood.
S Use wedges made of plastic or wood.
Never use metal to hold the cut open.

Avoid Obstructions
REDUCETHECHANCEOF
KICKBACK
S Recognize that kickback can happen.
With a basic understanding of kickback,
you can reduce the element of surprise
which contributes to accidents.
S Neverletthemoving chaincontact anyob-
ject at the tip of the guide bar.
S Keep 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.
S Keep your saw chain sharp and properly
tensioned. A looseordullchain can increase
the chance of kickback occurring. Follow
manufacturer’s chain sharpening and maintenance instructions. Check tension at regular intervals with the engine stopped, never
with the engine running. Make sure the bar
clamp nuts are securely tightened after tensioning the chain.
S Begin and continue cutting at full speed. If
the chain is moving at a slower speed, there
is greater chance of kickback occurring.
S Cut one log at a time.
S Use extreme caution when re-entering a
previous cut.
S Do not attempt cuts starting with the tip of
the bar (plunge cuts).
S Watch for shifting logs or other forces that
could close a cut and pinch or fall into chain.
S Use 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
6
Thumb on underside of
handlebar
Elbow locked
S Keep 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 encircling and
your left thumb under the front handlebar.
Keep your right hand completely around the
rear handle whether your are righthanded or
left handed. Keep your left arm straight with
the elbow locked.
S Positionyour left hand onthe fronthandle-
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.
S Standwithyourweightevenly balancedon
both feet.
S Stand slightly to the left side of the saw to
keep your body from being in a direct line
with the cutting chain.
S Do not overreach. You could be drawn or
thrown off balance and lose control of the
saw.
S Donot cut above shoulder height. It is diffi-
cult to maintain control of saw above
shoulder height.I
KICKBACK SAFETY FEATURES
WARNING: The following features are
included onyour saw to helpreduce the hazard
of kickback; however, such features will nottotally eliminate this dangerous reaction. As a
chain saw user, do not rely only on safety devices. 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.
S Reduced--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.

S Handguard, designed to reduce the chance
of your left hand contacting the chain if your
hand slips off the front handlebar.
S Position of front and rear handlebars, de-
signedwithdistancebetweenhandles 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 kickback occurs.
WARNING: DO NOT RELY UPON
ANYOFTHE DEVICESBUILTINTOYOUR
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. Yoursaw has a lowkickback
chainandbaras 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
servicingdealer, ortothenearestauthorized
master service dealer.
S Tipcontactinsomecases may cause alight-
ning fast reverse REACTION, kicking the
guide bar up and back toward the operator.
S Pinchingthe saw chainalong the top ofthe
guide bar may push the guide bar rapidly
back toward the operator.
S Eitherof these reactions maycauseyouto
lose control of the saw which could result
in serious injury. Do not rely exclusively

OPERATING YOUR UNIT
BEFORE STARTING ENGINE
WARNING: Be sure to read the fuel
informationinthe safety rules before you begin.Ifyoudonot understandthesafetyrules,
do not attempt to fuel your unit. Contact an
authorized service dealer.
BAR AND CHAIN LUBRICATION
The bar and chain require continuous lubrication. Lubrication is provided by the automatic 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 thechainand/
or discoloration of thebar.Only use Bar and
Chain Oil for bar and chain lubrication.
FUELING ENGINE
WARNING: Removefuel capslowly
when refueling.
This engine is certified to operate on unleaded
gasoline. Before operation, gasoline must be
9
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 with5liters 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
Experienceindicates that alcoholblendedfuels
(called gasohol or using ethanol or methanol)
can attract moisture which leads to separation
and formation of acids during storage. Acidic
gas can damage the fuel system of an engine
while in storage. T o avoid engine problems,
empty the fuel system before 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 thefueltank or permanent damage may
occur.
CHAIN BRAKE
Ensure chain brake is disengaged by pulling

CUTTING METHODS
IMPORTANT POINTS
S Check chain tension before first use and af-
ter 1 minute of operation. See CHAIN TENSION in the ASSEMBL Y section.
S Cut wood only. Do not cut metal, plastics,
masonry, non-wood building materials, etc.
S Thebumper spike may be used as a pivot
when making a cut.
S Stop the saw if the chain strikes a foreign
object. Inspectthesaw and repairpartsas
necessary.
S Keepthechainout ofdirtand sand. Evena
smallamountof dirt will quickly dull achain
and increase the possibility of kickback.
S Practice cutting a few smalllogs using the
following techniques togetthe“feel”ofusing your saw before you begin a major
sawing operation.
S Squeeze the throttle trigger and allow the
engine to reach full speed before cutting.
S Begin cutting with the saw frame
against the log.
S Keep the engine at full speed the entire
time you are cutting.
S Allow thechainto cutforyou. Exertonly
light downward pressure.
S Release the throttle trigger as soon as
the cut is completed, allowing the en-
gine to idle. If you run the saw at full
throttlewithoutacuttingload,unnecessary wear can occur.
S To avoid losing control when cut is com-
plete, do not put pressure on saw at end
of cut.
S Stopthe engine before settingthesaw down.
TREE FELLING TECHNIQUES
WARNING: Felling a tree requires
chain saw skills and experience. Inexperienced users should not fell trees. Do not attempt any task that makes you feel uncomfortable or unsure.
WARNING: Donotcut nearbuildings
or electrical wires if you do not know the direction of tree fall, at night since you will not
be able to see well, or during bad weather
such as rain, snow,orstrong winds. as fall is
unpredictable.
Carefully plan your sawing operation in advance. 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.
11
Natural conditions that can cause a tree to
fall in a particular direction include:
S The wind direction and speed.
S The lean of the tree. The lean of a tree
might not be apparent due to uneven or
slopingterrain. Useaplumbor leveltodetermine the direction of tree lean.
S Weight and branches on one side.
S Surrounding trees and obstacles.
Look for decay and rot. If the trunk isrotted,
it can snap and fall toward the operator.
Make sure there is enough room for the treeto
fall. Maintain a distance of
2-1/2 tree lengths
from the nearest person or other objects. Engine noise can drown out a warning call.
Remove dirt, stones, loose bark, nails, staples,
and wire from the tree where cuts are to be
made.

FELLING LARGE TREES
(15cmindiameterorlarger)
The notch method is used to fell large trees.
Anotchiscutonthe side ofthetreein thedesired 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
S Make notch cut by cutting the top of the
notch first. Cut through
1/3 of the diameter
ofthe tree.Nextcompletethenotch bycutting the bottom of the notch. See illustration. Once the notch is cut remove the
notch of wood from the tree.

S After removing the wood from the notch,
make the felling cut on the opposite side of
thenotch.This is doneby making a cut about
5 cm 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
controlthedirectionoffall. T oavoidkickback
or chain damage, use wood or plastic
wedges, but never steel or iron wedges.
S Bealerttosignsthatthetreeisreadytofall:
cracking sounds, widening of the felling cut,
or movement in the upper branches.
S Astree starts to fall, stop saw,put it down,
and get away quickly on your planned retreat path.
S DO NOT cut down a partially fallen tree with
your saw. Be extremely cautious with partially fallen trees that may be poorly supported. 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
S Cut only one log at a time.
S Cut shattered wood very carefully; sharp
piecesofwood could beflung toward operator.
S Use a sawhorse to cut small logs. Never
allow another person to hold the log while
cuttingandneverholdthe log with your leg
or foot.
S Do not cut in an area where logs, limbs,
and roots are tangled. Drag the logs into a
clear area before cutting by pulling out exposed 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 controlof the saw resulting in injury
and/or damage to the saw. Stop the saw,
drive a wedge of plastic or wood into the cut
untilthesawcanberemovedeasily. Restart
thesawandcarefully reenter the cut. Donot
attemptto restart yoursawwhenit is pinched
or hung in a log.
Turn saw OFF and use a plastic or
wooden wedge to force cut open.
12
Overcutting begins onthetop sideofthe log
with the saw against the log. When overcutting use light downward pressure.
Overcutting
Undercutting
Undercuttinginvolvescuttingontheundersideofthelog with top ofsawagainst thelog.
When undercutting use light upward pressure. 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 controlled in this position.
First cut on pressure side of log
Second cut
First cut on pressure side of log
Second cut
BUCKING WITHOUT A
SUPPORT
S Overcut through 1/3 of the diameter of the
log.
S Roll the log over and finish with a second
overcut.
S Give special attention to logs under strain
to prevent the saw from pinching. Make
the first cut on the pressureside to relieve
the stress on the log.
BUCKING USING A LOG OR SUPPORT STAND
S Remember your first cut is always on the
pressure side of the log.
S Your first cut should extend
1/3 of the
diameter of the log.
S Finish 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, platforms, a log, or in any positionwhich can cause
you to lose your balance or control of the saw.
IMPORTANT POINTS
S Watch out for springpoles. Use extreme
caution when cutting smallsize limbs. Slender material may catch the sawchain and be
whipped toward you or pull you off balance.
S Be alert for springback. Watch out for
branches that are bent or under pressure.
Avoid being struck by the branch or the
saw when the tensioninthe wood fibers is
released.
S Keep a clear work area. Frequently clear
branches out of the way to avoid tripping
over them.
LIMBING
S Alwayslimbatreeafter itiscutdown. Only
then can limbingbe done safely and properly.
S Leave the larger limbs underneath the
felled tree to support the tree as you work.
S Startatbase of the felled tree and work to-
ward the top, cutting branches and limbs.
Remove small limbs with one cut.
S Keep the tree between you and the chain
as much as possible.
S Remove larger, supporting branches with
thecuttingtechniques describedinBUCKING WITHOUT A SUPPORT.
S Always 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 thanyour shoulder.Get
a professional to do the job.

CHAIN SHARPENING
WARNING: Improper chain sharpen-
ing techniques and/or depth gauge maintenance will increase the chance of kickback
which can result in serious injury.
WARNING: Wear protective gloves
when handling chain. The chain is sharp and
can cut you even when it is not moving.
Conditions which indicate the need for chain
sharpening:
S Reduction in size of wood chips. The size
ofthewood chip will decreaseasthechain
gets duller until it becomes more like a
powder than a chip. Note that dead or
rotted wood will not produce a good chip.
S Saw cuts to one side or at an angle.
S Saw has to be forced through the cut.
Tools required:
S 5/32 inch (4 mm) diameter round file and
file holder
S Flat file
S Depth gauge tool
TO SHARPEN CHAIN:
1. MoveON/STOPswitchtotheSTOP
position.
2. Check chain for proper tension. Adjust
chain tension if necessary.
3. Sharpen cutters.
S To sharpen the cutters, position the
file holder level (90˚) so that it rests
on the top edges of the cutter and
depth gauge.
NOTE: The chain has both left and
right hand cutters.

If you require further assistance or are unsure
about performing this procedure, contact your
authorized service dealer.
CARBURETOR ADJUSTMENT
WARNING: The chain will be moving
during most of this procedure. Wear your protective equipment and observe all safety precautions. 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:
S Chain moves at idle. See IDLE SPEED--T
adjusting procedure.
S Sawwill not idle. See IDLE SPEED--T ad-
justing procedure.
Idle Speed-- T
Allow engine to idle. If the chain moves, idle
istoo fast. If theenginestalls,idleis tooslow.
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 .
S Turnidle speed screw (T) clockwise to in-
crease engine speed.
S Turn idle speed screw (T) counterclock-
wise to decrease engine speed.
STORAGE
WARNING: Stop engine and allow to
cool, and secure the unit before storing or
transporting in a vehicle. Store unit and fuel
in an area where fuel vapors cannot reach
sparks or open flames from water heaters,
electric motors or switches, furnaces, etc.
Storeunit withallguards inplace. Positionso
that any sharp object cannot accidentally
cause injury to passersby.Store the unit out
of reach of children.
S Before storing, drain all fuel from the unit.
Start engine and allow to run until it stops.
S Clean the unit before storing. Pay particu-
lar attention to the air intake area, keeping
it free of debris. Use a mild detergent and
sponge to clean the plastic surfaces.
S Donotstoretheunit orfuelin aclosedarea
where fuel vapors can reach sparks or an
openflamefromhotwater heaters, electric
motors or switches, furnaces, etc.
S Store in a dry area out of the reach of chil-
dren.
S Ensure the machine is cleaned and that a
complete service is carried out before
long--term storage.
S The guide bar and chain must always be
covered with a scabbard when the machine
is being transported or in storage in order to
prevent accident 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.
CAUTION: It is important to prevent
gum deposits from forming in essential fuel
system parts such as the carburetor, fuel filter,fuel hose, or fuel tank during storage. Alcohol blended fuels (calledgasohol or using
ethanol or methanol) can attract moisture
which leads to fuel mixture separation and
formationofacids duringstorage. Acidic gas
can damage the engine.
