INTRODUCTION
Dear Customer,
Thank you for choosing a McCulloch product. You are thereby part of a story that started long
ago, when the McCulloch Corporation started its manufacturing of engines during World War II. In
1949, when McCulloch introduced its first light one-man chain saw, woodworking would never be
the same again.
The line of innovative chain saws would continue over the decades, and business was expanded,
first by airplane and kart engines in the 1950s, then by mini chainsaws in the 1960s. Later, in the
1970s and 80s, trimmers and blower/vacs were added to the range.
Today, as a part of the Husqvarna group, McCulloch continues the tradition of powerful engines,
technical innovations, and strong designs that have been our hallmarks for more than half a century.
Lowering fuel consumption, emissions and noise levels are of top priority to us, as is improving safety
and user-friendliness.
We certainly hope that you will be satisfied with your McCulloch product, as it is designed to be
your companion for a long time. By following this operators manual’s advice on usage, service,
and maintenance, its lifespan can be extended. If you should need professional help with repair or
service, please use the Service Locator at www.mcculloch.com.
McCulloch has a policy of continuous product development and therefore reserves the right to
modify the design and appearance of products without prior notice.
This manual can also be downloaded at www.mcculloch.com.

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.
WARNING: This machine produces
an electromagnetic field during operation. This
field may under some circumstances interfere
with active or passive medical implants. To reduce the risk of serious or fatal injury, we recommend persons with medical implants to
consult their physician and the medical implant
manufacturer before operating this machine.
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
securely assembled. Always 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.
S Secure the machine during transport.

GENERAL SAFETY PRECAUTIONS
S Chain brake. Your 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 THAT THE CHAIN 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.
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, MAINTAINING
AND SERVICING CHAIN SA W
SAFETY EQUIPMENT
WARNING: Never use a chain saw
with defective safety equipment. Safety
equipment must be inspected and maintained. If your chain saw does not pass inspection, take the saw to your nearest service dealer for repair.
S Chain brake. Brush off any wood dust, res-
in and dirt from the chain brake and clutch
drum. Dirt and wear can impair operation of
the brake. For additional information, see
OPERATING YOUR UNIT section.
S Throttle trigger lock--out. Check that the
throttle trigger can not be operated until the
throttle lock--out is pressed.
S Chain catcher. Check that the chain
catcher is not damaged and is firmly attached to the body of the chain saw.
S Vibration damping system. Regularly
check the vibration damping units for
cracks or deformation. Make sure the
vibration damping units are securely attached to the engine unit and handle unit.
S ON/STOP switch. Start the engine and
make sure the engine stops when you move
the ON/STOP switch to the STOP position.
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 McCulloch accessories and re-
placement 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 foreign object 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,
5
GENERAL SAFETY PRECAUTIONS
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 to move 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.
Kickback Path
lar 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.

REDUCE THE CHANCE OF
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 the moving 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 regu-
Thumb on underside of
handlebar
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.

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 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-
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 OF THE DEVICES BUILTINTO YOUR
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.

FUEL HANDLING
FUEL
Note! The machine is equipped with a twostroke engine and must always be run using
a mixture of petrol and two-stroke oil. It is important to accurately measure the amount of
oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts
of fuel, even small inaccuracies can drastically affect the ratio of the mixture.
WARNING: Always ensure there is
adequate ventilation when handling fuel.
PETROL
S Use good quality unleaded or leaded petrol.
S The lowest recommended octane grade is
90 (RON).
S If you run the engine on a lower octane grade
than 90 so- -called knocking can occur. This
gives rise to a high engine temperature and
increased bearing load, which can result in
serious engine damage.
S When working with continuous high revs
(e.g. limbing) a higher octane is recommended.
Running--in
AvoId running at a too high speed for extended periods during the first 10 hours.
TWO-STROKE OIL
S For best results and performance use Uni-
versal, Universal powered by McCulloch
two-- stroke engine oil, which is specially
formulated for our air cooled two--stroke
engines.
S Never use two-stroke oil intended for water-
cooled engines, sometimes referred to as
outboard oil (rated TCW).
S Never use oil intended for four--stroke en-
gines.
S A poor oil quality and/or too high oil/fuel ra-
tio may jeopardise function and decrease
the lifetme of catalytic converters.
MIXING RATIO
1:50 (2%) with Universal, Universal powered
by McCulloch two-stroke oil.
1:33 (3%) with oils class JASO FB or ISO EGB
formulated for air-cooled, two-stroke engines.
Petrol, litre Two--Stroke Oil, litre

5 0,10 0,15
10 0,20 0,30
15 0,30 0,45
20 0,40 0,60
MIXING
S Always mix the petrol and oil in a clean
container intended for fuel.
S Always start by filling half the amount of the
petrol to be used. Then add the entire
amount of oil. Mix (shake) the fuel mixture.
Add the remaining amount of petrol.
S Mix (shake) the fuel mixture thoroughly be-
fore filling the machine’s fuel tank.
S Do not mix more than one month’s supply
of fuel at a time.
S If the machine is not used for some time
the fuel tank should be emptied and
cleaned.
CHAIN OIL
S We recommend the use of special oil
(chain oil) with good adhesion characteristics.
S Never use waste oil. This results in dam-
age to the oil pump, the bar and the chain.
S It is important to use oil of the right grade
(suitable viscosity range) to suit the air
temperature.
S In temperatures below 0°C(32°F) some
oils become too viscous. This can overload the oil pump and result in damage to
the oil pump components.
S Contact your service dealer when choos-
ing chain oil.
FUELING
WARNING: Taking the following pre-
cautions will lessen the risk of fire: do not
smoke and do not place any hot objects in
the vicinity of fuel; always stop the engine
and let it cool for a few minutes before refueling; when refueling, open the fuel cap slowly
so that any excess pressure is released
gently; tighten the fuel cap carefully after refueling; always move the machine away
from the refueling area and source before
starting.
Clean the area around the fuel cap. Clean
the fuel and chain oil tanks regularly. The fuel
filter must be replaced at least once a year.
Contamination in the tanks causes malfunction. Make sure the fuel is well mixed by
shaking the container before refuelling. The
capacities of the chain oil tank and fuel tank
are carefully matched. You should therefore
always fill the chain oil tank and fuel tank at
the same time.
WARNING: Fuel and fuel vapour are
highly flammable. Take care when handling
fuel and chain oil. Be aware of the risks of
fire, explosion and those associated with inhalation.

DIFFICULT STARTING (or starting a flooded engine)
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.

WORKING TECHNIQUES
CHAIN BRAKE
WARNING: 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
cuttingwiththesaw.
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 chain brake
must be disengaged.
Disengaged
Engaged
IMPORTANT POINTS
WARNING: Sometimes wood chips
get stuck in the clutch cover causing the chain
to jam. Always stop the engine before cleaning.
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.
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 opera tor. Make
sure there is enough room for the tree to fall.
Maintain a distance of
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.

Direction of Fall
FELLING LARGE TREES
(15 cm in diameter or larger)
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 Be alert to signs that the tree is ready to fall:
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.
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.
Turn saw OFF and use a plastic or
wooden wedge to force cut open.
Overcutting begins on the top sideof the log
with the saw against the log. When overcutting use light downward pressure.
Overcutting
Undercutting
Undercuttinginvolves 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.
First cut on pressure side of log

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.
13
WORKING TECHNIQUES
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.

WARNING: Never climb into a tree to
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.
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 treeafter 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.
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.

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. T ake
your unit to the place of purchase if purchased
from a servicing dealer, or to the nearest authorized master service dealer.
BRAKING FUNCTION CONTROL
CAUTION: The chain brake must be
checked several times daily. The engine
must be running when performing this procedure. This is the only instance when the saw
should be placed on the ground with the engine running.
Place the saw on firm ground. Grip the rear
handlewith your right hand and the front handle 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.
AIR FILTER
CAUTION: Do not clean filter in gaso-
line or other flammable solvent to avoid
creating a fire hazard or producing harmful
evaporative emissions.
Cleaning the air filter:
A dirty air filter decreases engine performance 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.
3. Wash the filter in soap and water. Rinse
in clean cool water. Air dry completely
before reinstalling.
4. Reinstall parts.

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
of the wood chip will decrease as the chain
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.

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 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 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 Turn idle speed screw (T) clockwise to in-
crease engine speed.
S Turn idle speed screw (T) counterclock-
wise to decrease engine speed.
STORAGE
S Store in a dry area out of the reach of chil-
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 closed area
where fuel vapors can reach sparks or an
openflame from hot water heaters, electric
motors or switches, furnaces, etc.
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 (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.

INTRODUCTION
Cher client,
Nous vous remercions d’avoir choisi un produit McCulloch! Vous faites désormais partie d’une
histoire débutée il y a longtemps, lorsque l’entreprise McCulloch commença à fabriquer des
moteurs pendant la Seconde Guerre mondiale. En 1949, McCulloch lançait sa première tronçonneuse légère à utilisateur unique et révolutionnait le travail du bois à tout jamais.
La gamme de trononneuses innovantes allait se développer au fil des décennies et les activités
se diversifier, d’abord avec des moteurs d’avion et de kart dans les années 1950, puis avec des
mini--tronçonneuses dans les années 1960. Plus tard, dans les années 1970 et 1980, les coupe-herbes et aspiro-- souffleurs venaient compléter la gamme.
Aujourd’hui, McCulloch a rejoint le groupe Husqvarna et poursuit la tradition de moteurs puissants, d’innovations techniques et de conceptions résistantes, nos marques de fabrique depuis
plus d’un siècle. La réduction de la consommation en carburant, des émissions et des niveaux
sonores est notre priorité, tout comme l’amélioration de la sécurité et de la convivialité du produit.
Nous espérons que ce produit McCulloch vous donnera toute satisfaction et qu’il vous accompagnera pendant de longues années. Le respect des conseils dece manuel d’utilisation relatifs à
l’utilisation, à l’entretien et à la maintenance permettra de prolonger sa durée de vie. Si vous avez
besoin de l’aide d’un professionnel pour une réparation ou un entretien, veuillez utiliser le service
de localisation sur www.mcculloch.com.
McCulloch travaille continuellement au développement de ses produits et se réserve le droit d’en
modifier, entre autres, la conception et l’aspect sans préavis.

RECUL
AVERTISSEMENT: Evitez le recul
qui peut entraîner des blessures graves. Le
Recul est le mouvemen t 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’une autre bûche ou branche, ou quand le
bois se referme et pince la chaîne de la
tronçonneuse 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.
S Le Recul de Rotation peut se produire
quand la chaîne en mouvement entre en
contact avec un objet à l’extrémité supérieure du bout de la barre-guide. Ce contact peut enfoncer la chaîne dans cet objet, ce qui l’arrête pour un instant. Le
résultat est une réaction ultra-rapide qui
projette la barre-guide vers le haut et l’arrière, vers l’utilisateur.
S Le 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 inverse de la rotation de la chaîne. La tronçonneuse directement vers l’utilisateur.
S Le 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 facilement faire détruire l’opérateur la commande
de la tronçonneuse.
Évitez le pincement--recul:
S Soyez très vigilant des situations ou des ob-
structions qui pourraient faire serrer la partie
supérieure ou autrement arrêter la chaîne.
S Ne coupez pas plus d’un rondin d’une fois.
S Ne tordez pas la tronçonneuse lorsque
vous l’enlevez d’une coupure ascendante
lorsque vous sectionnez des rondins.
Évitez les rétraction:
S Quand 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.
S Employez des cales en plastique ou bois, ja-
mais en métal, pour tenir la coupure ouverte.

REDUIRE LES RISQUES DE
RECUL
S Souvenez-- vous que le recul existe. En
ayant une connaissance de base du recul,
vous pouvez réduire les risques entraînant des accidents.
S Ne touchez aucun objet avec le bout du
barre- -guide lorsque la chaîne est en mouvement.
S Dégagez la zone de travail de tout objet
encombrant tel que des arbres, branches,
pierres, haies, souches etc. Enlevez ou
évitez les objets encombrants que votre
tronçonneuse pourrait rencontrer lorsque
vous coupez une bûche ou une branche.
S Maintenez 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.
S Commencez et continuez à couper à plein
régime. Si la chaîne tourne plus lentement, le risque de recul sera plus grand.
S Ne coupez qu’une bûche à la fois.
S Faites très attention lorsque vous entrez à
nouveau dans une coupe.
S N’essayez pas de couper avec le bout du
barre-- guide (coupe en plongée).
26
INSTRUCTIONS GÉNÉRALES DE SÉCURITÉ
S Faites attention aux bûches mobiles et au-
tres facteurs pouvant refermer la coupe et
bloquer ou tomber sur la chaîne.
S Utilisez le barre--guide et la chaîne au re-
cul réduit définis pour votre tronçonneuse.
MAINTENEZ LE CONTRÔLE

DISPOSITIFS DE SÉCURITÉ
POUR LE RECUL
AVERTISSEMENT: Les disposi--
tifs suivants sont fournis avec votre tronçonneuse pour réduire le risque de recul ; de tels
conseils ne le supprimeront néanmoins jamais entièrement. En tant qu’utilisateur, ne
vous fiez pas uniquement aux équipements
de sécurité. Vousdevez suivre toutes les recommandations, précautions et conseils de
maintenance dans ce manuel pour éviter le
recul et d’autres manoeuvres risquant d’entraîner des blessures graves.
S Un barre--guide au recul réduit, conçu avec
un petit rayon d’extrémité permettant de réduire la zone de risque de recul au bout de la
barre. Un barre--guide au recul réduit a été
elaboré pour réduire de façon importante le
nombre et la gravité des reculs.

S Tenez 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
recul 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
complètement la poignée arrière votre
main droite. Que vous soyez gaucher ou
droitier ne joue aucun rôle. Votrebras gauche doit être tendu et le coude bloqué.
S Placez 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’inversez jamais les positions des mains,
quelle que soit la coupe.
S Tenez--vous sur deux pieds, le poids éga-
lement réparti.
S Positionnez-- vous légèrement à gauche
de la tronçonneuse pour ne pas vous trouver dans une ligne directe avec la chaîne
de coupe.
S Ne soyez pas trop tendu. Vous risqueriez
de perdre l’équilibre et le contrôle de la
tronçonneuse.
S Ne coupez aucun objet situé au--dessus
de vos épaules. Il est difficile de contrôler
la tronçonneuse à cette hauteur.
Barre symétrique
S Une chaîne au recul réduit a été élaborée
avec un indicateur de profondeur et un
maillon de protection pour dévier la force
de recul et permettre au bois d’entrer progressivement dans la coupeuse.
