S Keep 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.
S Do 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 mentally alert. Chain saw work is strenuous. If
you have any condition that might be aggravated by strenuous work, check with your
doctor before operating a chain saw.
S Carefully plan your sawing operation in ad-
vance. Donot 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
WARNING: Long term inhalation of
the engine’s exhaust fumes, chain oil mist and
dust from sawdust can result in serious personal injury.
S Do not operate a chain saw with one hand.
Serious injury to the operator, helpers, bystanders or any combination of these persons may result from one-handed operation.
A chain saw is intended for two-handed use.
S Operate the chain saw only in a well-venti-
lated outdoor area.
S Do not operate saw from a ladder or in a tree,
unless you are specifically trained to do so.
S Make 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.
S Do not put pressure on the saw at the end of
the cut. Applying pressure can cause you to
lose control of the chain saw when the cut is
completed and may cause serious personal
injury.
S Stop the engine before setting the saw down.
S Do not operate a chain saw that is damaged,
improperly adjusted, or not completely and
secur ely assembled. Alw ays replace bar,
chain, hand guard, or chain brake immediately if it becomes damaged, broken or is
otherwise removed.
S With 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.
CHAIN SAW SAFETY EQUIPMENT
In this section, the safety feature s of
NOTE:
the chain saw and their function are explained.
For inspection and maintenance, see instructions in the CHECKING, MAINTAINING 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 our chain saw is equipped
with a chain brake that is designed to stop
the chain from moving.
WARNING: The chain brake is de-
signed 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 THATTHE CHAIN
BRAKE WILL PROTECT YO U 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.
S Vibration damping system. Your chain
saw is equipped with a vibration damping
systemthat is designed to minimize vibration and make operation easier.
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 antivibration system does 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.
S ON/STOP switch. The ON/STOP switch
should be used to stop the engine.
CHECKING, MAINTAINI NG AND

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 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 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 Keep the 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 Eliminate 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 engine to cool before refueling.
S Mix and pour fuel in an outdoor area on bare
ground; store fuel in a cool, dry, well ventilated place; and use an approved, marked
container for all fuel purposes. Wipe up all
fuel spills before starting saw.
S Move at least 10 feet (3 meters) from fuel-
ing site before starting engine.
S Turn 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.
S Store 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 bar contacts any object such as a log or branch, or
when the wood closes in and pinches the
saw chain in the cut. Contacting a foreignobject in the wood can also result in loss of
chain saw control.
S Rotational Kickback can occur when the
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
saw tomove in the opposite direction of the
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 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:
S Be extremely aware of situations or obstruc-
tions that can cause 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 with the engine at full
speed and the saw housing against wood.
S Use wedges made of plastic or wood.
Never use metal to hold the cut open.

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 Never let themoving chain contact any ob-
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 loose or dull chain 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.
5
S Do not attempt cuts starting with the tip of
K
L
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
Stand to the left of
the saw
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 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 right handed or
left handed. Keep your left arm straight with
the elbow locked.
S Position 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.
S Stand with your weight evenly balanced on
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 Do not 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 on your saw to help reduce the hazard
of kickback; however, such features will not totally 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

hand slips off the front handlebar.
S Position 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 kickback occurs.
WARNING: DO NOT RELY UPON
ANY O F THE DEVICES BUILTINTOYOUR
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 low kickback
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 authorized
master service dealer.
S Tip contact in some cases may cause a light-
ning fast reverse REACTION, kicking the
guide bar up and back toward the operator.
S Pinching the saw chain along the top of the
guide bar may push the guide bar rapidly
back toward the operator.
S Either of these reactions may cause you to
lose control of the saw which could result
in serious injury. Do not rely exclusively
uponthe safety devices built into your saw.

OPERATING YOUR UNIT
BEFORE STARTING ENGINE
WARNING: Be sure to read the fuel
information in the safety rules before you begin. If you donot 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 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 the chain and/
or discoloration of the bar. Only use Bar and
Chain Oil for bar and chain lubrication.
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 damage the fuel system of an engine
while in storage. To 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 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 handle 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 CARBURETOR 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.

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 authorized master service dealer.
S This saw is equipped with a chain brake.
The brake is designed to stop the chain if
kickback occurs.
S The inertia activated chain brake is activated
if the front hand guard is pushed forward, either manually or by centrifugal force.
S If the brake is already activated, it is disen-
gaged by pulling the front hand guard back
toward the front handle as far as possible.
S When cutting with the saw, the chainbrake
must be disengaged.

CUTTING METHODS
IMPORTANT POINTS
S Check chain tension before first use and af-
ter 1 minute of operation. See CHAIN TENSION in the ASSEMBLY section.
S Cut wood only. Do not cut metal, plastics,
masonry, non-wood building materials, etc.
S The bumper spike may be used as a pivot
when making a cut.
S Stop the saw if the chain strikes a foreign
object. Inspect the saw and repair parts as
necessary.
S Keep the chain out of dirt and sand. Even a
small amount of dirt will quickly dull a chain
and increase the possibility of kickback.
S Practice cutting a few small logs using the
following techniques to get the “feel” of using 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.
10
S Keep the engine at full speed the entire
time you are cutting.
S Allow the chain to cut for you. Exert only
light downward pressure.
S Release the throttle trigger as soon as
the cut is completed, allowing the engine to idle. If you run the saw at full
throttle without a cutting load, 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 Stop the engine before setting the saw 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: Do not cut near buildings
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, or strong 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.
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
sloping terrain. Use a plumb or level to determine 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 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
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.
A notch is cut on the side of the tree in the desired 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
of the tree. Next complete the notch by cutting the bottom of the notch. See illustration. Once the notch is cut remove the
notch of wood from the tree.
First cut
Notch
Second cut
S After 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
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.
Hinge holds tree on stump and helps
control fall
Closing
of notch
NOTE: Before felling cut is complete, use
wedges to open the cut when necessary to
control the directionof fall. Toavoid kickback
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 As tree 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.
11
Important points
S Cut only one log at a time.
S Cut shattered wood very carefully; sharp
pieces of wood could be flung toward operator.
S Use 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.
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 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.
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 pressure side 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
diameter of the log.
S Finish with your second cut.

Overcutting begins on the top side of the log
with the saw against the log. When overcutting use light downward pressure.
Overcutting
Undercutting
Undercutting involves cutting on the underside of the log with top of saw against the log.
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.

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 position which can cause
you to lose your balance or control of the saw.
IMPORTANT POINTS
S Watch out for springpoles. Use extreme
caution when cutting small size limbs. Slender material may catch the saw chain and be
whipped toward you or pull you off balance.
12
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 tension in the wood fibers is
released.
S Keep a clear work area. Frequently clear
branches out of the way to avoid tripping
over them.
LIMBING
S Always limb a tree after it is cut down. Only
then can limbing be done safely and properly.
S Leave the larger limbs underneath the
felled tree to support the tree as you work.
S Start at base 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
the cutting techniques described in BUCKING WITHOUT A SUPPORT.
S Always use an overcut to cut small and
freely hanging limbs. Undercutting could
cause limbs to fall and pinch saw.
SERVICE AND ADJUSTMENTS
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.
S Make your fist cut
the bottom of the limb.
S Next make a 2nd cut all the way through
the limb. Then cut a third overcut leaving
a 3 to 5 cm collar from the trunk of the tree.

or on the decal located on the chain saw.
SPARK PLUG
The spark plug should be replaced each
year to ensure the engine starts easier and
runs better. Ignition timing is fixed and nonadjustable.
1. Loosen 3 screws on cylinder cover.
2. Remove the cylinder cover.
3. Pull off the spark plug boot.
4. Remove spark plug from cylinder and
discard.
5. Replace with Champion RCJ--7Y spark
plug and tighten securely with a 19 mm
socket wrench. Spark plug gap should
be 0,5 mm.
6. Reinstall the spark plug boot.
7. Reinstall the cylinder cover and 3
screws. Tighten securely.
CHAIN SHARPENING
WARNING: Failure to properly sharp-
en the chain considerably increases the risk of
kickback.
Chain sharpening is a complicated task that
requires special tools. We recommend that
you refer chain sharpening to a professional
chain sharpener.
CARBURETOR ADJUSTMENT
WARNING: Thechainwillbemoving
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 Saw 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.
S Turn idle 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.
Store unit with all guards in place. Position so
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 Do not store the unit or fuel in a closedarea
where fuel vapors can reach sparks or an
openflame from hot water 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 imp ortant 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 (called gasohol or using
ethanol or methanol) can attract moisture
which leads to fuel mixture separation and
formation of acids during storage. Acidic gas
can damage the engine.
