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.

SWear protective gear. Always use steel-toed safety footwear with non-slip soles; snug-fit- ting clothing; heavy-duty, non-slip gloves; eye protection such as non-fogging, vented goggles or face screen; an approved safety hard hat; and sound barriers (ear plugs or mufflers) to protect your hearing. Secure hair

above shoulder length.

S Always use approved hearing protection. Regular users should have hearing checked

regularly as chain saw noise can damage hearing. Long--term exposure to noise can result in permanent hearing impairment.

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 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.

SCarefully plan your sawing operation in advance. 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

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.

SDo 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.

SOperate 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.

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 of the chain saw when the cut is

completed and may cause serious personal injury.

S Stop the engine before setting the saw down.

SDo 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.

CHAIN SAW SAFETY EQUIPMENT

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, 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 main-

tenance 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.

GENERAL SAFETY PRECAUTIONS

SChain 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 designed to catch the saw chain if it breaks.

SVibration damping system. Your chain saw is equipped with a vibration damping system that 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.

SON/STOP switch. The ON/STOP switch should be used to stop the engine.

CHECKING, MAINTAINING AND SERVICING CHAIN SAW 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.

SChain brake. Brush off any wood dust, resin 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 at-

tached 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

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.

S Keep the handles dry, clean, and free of oil or fuel mixture.

SKeep fuel and oil caps, screws, and fasteners securely tightened.

S Use only McCulloch accessories and replacement 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 engine to cool before refueling.

SMix 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.

SMove at least 10 feet (3 meters) from fueling 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 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.

SRotational 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.

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.

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:

SBe extremely aware of situations or obstructions 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.

SDo not twist the saw as the bar is withdrawn 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.

Working Area

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 object at the tip of the guide bar.

SKeep the working area free from obstructions 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-

lar intervals with the engine stopped, never with the engine running. Make sure the bar clamp nuts are securely tightened after tensioning 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.

S Cut 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).

S Watch 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

Stand to the left the saw

Never reverse hand positions

Elbow locked

Thumb on underside of handlebar

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 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.

SPosition your left hand on the front handlebar 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.

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.

GENERAL SAFETY PRECAUTIONS

SDo not cut above shoulder height. It is difficult 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 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.

SHandguard, designed to reduce the chance of your left hand contacting the chain if your

hand slips off the front handlebar.

SPosition of front and rear handlebars, designed 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 BUILT INTO 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. Your saw 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.

STip contact in some cases may cause a lightning 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.

8.If chain is too loose, it will sag below the guide bar. DO NOT operate the saw if the chain is loose.

NOTE: The chain is tensioned correctly when

the weight of the chain does not cause it to sag below the guide bar (with the chain saw sitting in an upright position), but the chain still moves.

WARNING: If the saw is operated with a loose chain, the chain could jump off the guide bar and result in serious injury.

WARNING: Muffler is very hot during

and after use. Do not touch the muffler or allow combustible material such as dry grass or fuel to do so.

9

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.

SThe lowest recommended octane grade is 90 (RON).

SIf 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.

SWhen 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

SFor best results and performance use Universal, Universal powered by McCulloch two--stroke engine oil, which is specially formulated for our air cooled two--stroke

engines.

SNever use two-stroke oil intended for watercooled engines, sometimes referred to as

outboard oil (rated TCW).

SNever use oil intended for four--stroke engines.

SA poor oil quality and/or too high oil/fuel ratio 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
	2% (1:50)	3% (1:33)
5	0,10	0,15
10	0,20	0,30
15	0,30	0,45
20	0,40	0,60

MIXING

SAlways mix the petrol and oil in a clean container intended for fuel.

SAlways 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 before filling the machine’s fuel tank.

S Do not mix more than one month’s supply of fuel at a time.

SIf 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.

SNever use waste oil. This results in damage to the oil pump, the bar and the chain.

SIt 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.

SContact your service dealer when choosing 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.

10

STARTING AND STOPPING

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.

Use only 15″ -- 18″ (40 -- 45 cm) of rope per pull.

Hold saw firmly while pulling starter rope. Starter Rope Handle

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 cutting with the saw.

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, either manually or by centrifugal force.

S If the brake is already activated, it is disengaged 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.

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.

SCheck chain tension before first use and after 1 minute of operation. See CHAIN TEN-

SION 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.

SStop the saw if the chain strikes a foreign object. Inspect the saw and repair parts as necessary.

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 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.

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 engine to idle. If you run the saw at full throttle without a cutting load, unnecessary wear can occur.

STo avoid losing control when cut is complete, 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 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.

Plan a clear retreat path

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

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 cutting the bottom of the notch. See illustration. Once the notch is cut remove the notch of wood from the tree.

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: 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. Slen-

der 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.

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.

S Leave the larger limbs underneath the felled tree to support the tree as you work.

SStart at base of the felled tree and work toward 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 3 to 5 cm collar from the trunk of the tree.

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:

SReduction 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.Move ON/STOP switch to the STOP position.

2.Check chain for proper tension. Adjust chain tension if necessary.

3.Sharpen cutters.

STo 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.

SSaw will not idle. See IDLE SPEED--T adjusting 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.

STurn idle speed screw (T) counterclockwise 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.

SBefore 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.

SDo not store the unit or fuel in a closed area where fuel vapors can reach sparks or an open flame from hot water heaters, electric motors or switches, furnaces, etc.

SStore in a dry area out of the reach of children.

SEnsure 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 accom-

pagnera pendant de longues années. Le respect des conseils de ce 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.

tion aux vibrations provoquées par un outillage à main et à essence peut entraîner des lésions des vaisseaux sanguins ou des nerfs des doigts, de la main et des articulations chez les personnes enclines à des troubles de la circulation ou à des enflures anormales. Certaines personnes habituellement saines ont connu des problèmes de vaisseaux sanguins lors d’une utilisation prolongée dans le froid. Si des symptômes tels qu’engourdissement,

douleurs, affaiblissement, changement de la couleur ou du grain de la peau ou encore perte de sensibilité dans les doigts, les mains ou les articulations apparaissent, arrêtez d’utiliser cet appareil et consultez un médecin. Un système anti--vibration ne permet pas d’éviter ces problèmes. Les personnes travaillant régulièrement ou continuellement avec un appareil électrique doivent contrôler minutieusement leur condition physique et l’état de l’appareil.

S Interrupteur d’arrêt. Le interrupteur d’arrêt est utilisé pour arrêter le moteur.

CONTRÔLE, MAINTENANCE ET ENTRETIEN DES ÉQUIPEMENTS DE SÉCURITÉ DE LA TRONÇONNEUSE

AVERTISSEMENT: N’utilisez ja-

mais une machine dont les équipements de sécurité sont défectueux. Les équipements

de sécurité doivent être contrôlés et entretenus. Si les contrôles ne donnent pas un résultat positif, faites réparer votre machine par un atelier d’entretien.

SFrein de chaîne. Nettoyer le frein de chaîne et le tambour d’embrayage (copeaux, résine, saletés). La saleté et l’usure compromettent le bon fonctionnement du frein. Pour l’information additionnelle, voyez le section FONCTIONNEMENT.

S Verrouillage des gaz. Vérifier que la gâchette des gaz ne peut pas être serré jusqu’à ce que le verrouillage des gaz soit serré.

SCapteur de chaîne. Vérifier que le capteur de chaîne est en bon état et qu’il est

bien fixé dans le corps de la tronçonneuse.

SSystème anti-vibrations. Vérifier régulièrement l’état des éléments afin de détecter fissures et déformations. S’assurer que les éléments sont bien fixés entre le

moteur et les poignées.

SInterrupteur d’arrêt. Mettre le moteur en marche et s’assurer qu’il s’arrête lorsque le interrupteur d’arrêt est amené en position d’arrêt.

MAINTENEZ VOTRE TRONÇONNEUSE EN BON ETAT

SLa maintenance de la tronçonneuse doit être effectuée par un revendeur agréé sauf pour les objets cités dans la section maintenance de ce manuel. Par exemple, si des outils non conformes sont utilisés pour ôter ou maintenir le volant lors de la répa-

ration du boîtier, le volant pourrait être endommagé et éclater ultérieurement.

S Assurez--vous que la chaîne de la tronçonneuse s’arrête lorsque la manette de puissance est relâchée. Pour des ajustements, reportez--vous à la section « RÉGLAGES DU CARBURATEUR ».

S N’entreprenez aucune modification sur votre tronçonneuse. N’utilisez que les accessoires fournis ou spécifiquement re-

commandés par le fabricant.

S Les poignées doivent être sèches et propres, sans tâches d’huile ou de carburant.

SLes bouchons de carburant et d’huile ainsi que les vis et les écrous doivent être bien

serrés.

SN’utilisez que des accessoires et pièces de rechange McCulloch recommandés.

MANIEZ LE CARBURANT AVEC PRECAUTION

SNe fumez pas lorsque vous maniez du carburant ou en utilisant la tronçonneuse.

25

INSTRUCTIONS GÉNÉRALES DE SÉCURITÉ

S Eliminez toutes les sources éventuelles d’étincelles ou de flammes dans les endroits dans lesquels vous mélangez ou versez le carburant. Evitez la fumée, les flammes ou toute activité pouvant provoquer des étincelles. Laissez le moteur se refroidir avant de remettre du carburant.

SMélangez et versez du carburant à l’extérieur sur un sol plat ; entreposez le carburant dans un endroit frais, sec et bien aéré ; utilisez un récipient agréé et étiqueté pour contenir du carburant. Essuyez le carburant

répandu avant de démarrer la tronçonneuse.

SEcartez--vous d’au moins 3 mètres de l’endroit où vous avez rempli le réservoir avant de démarrer le moteur.

S Eteignez le moteur et laissez la tronçonneuse refroidir dans un endroit sans carburant, feuilles sèches, paille, papier, etc. Retirez lentement le bouchon et rechargez l’appareil.

SEntreposez l’appareil et le carburant dans un endroit où les vapeurs de carburant ne risquent pas d’entrer en contact avec des étincelles ou des flammes provenant de chauffe--eau, moteurs et interrupteurs électriques, chaudières, etc.

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’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 con-

tact 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

chaîne cause un renversement de la force 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.

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 facilement faire détruire l’opérateur la commande de la tronçonneuse.

Évitez le pincement-recul:

SSoyez très vigilant des situations ou des obstructions 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:

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, jamais 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.

SDégagez 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.

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. S Ne coupez qu’une bûche à la fois.

S Faites très attention lorsque vous entrez à nouveau dans une coupe.

SN’essayez pas de couper avec le bout du barre--guide (coupe en plongée).

26

INSTRUCTIONS GÉNÉRALES DE SÉCURITÉ

SFaites attention aux bûches mobiles et autres facteurs pouvant refermer la coupe et

bloquer ou tomber sur la chaîne.

Le coude doit être tendu

Placez le pouce sous le guidon

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 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. Votre bras gauche doit être tendu 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’inversez jamais les positions des mains,

quelle que soit la coupe.

S Tenez--vous sur deux pieds, le poids également 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 tronçonneuse.

SNe coupez aucun objet situé au--dessus de vos épaules. Il est difficile de contrôler la tronçonneuse à cette hauteur.

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 ja-

mais entièrement. En tant qu’utilisateur, ne vous fiez pas uniquement aux équipements de sécurité. Vous devez 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.
