Proper storagepreparation is essential for keepingyour enginetrouble-free and lookinggood.The followingsteps will help tokeep rust and corrosion fromimpairingyour engine’s function aappearance, and will make theengineeasier tostart when you uit again.

If theenginehasbeen running,allow it to cool for at leasthalf anhour beforecleaning. Cleanall exterior surfaces, touchupanydamaged paint, and coatother areas thatmay rustwith a lightfiof oil.

Using a garden hose or pressure washing equipment can force water into the air cleaner or muffler opening. Water in the air

cleaner will soak the air filter, and water that passes through the air filter or muffler can enter the cylinder, causing damage.

Gasolinewill oxidize and deterioratein storage. Deteriorated

gasoline will causehard starting, and it leaves gum deposits thatclogthe fuel system. If the gasoline in your engine deterioratesduringstorage, youmay needto havethe carburetor, and otherfuel systemcomponents,servicedor replaced.

Thelength of time thatgasoline can beleft in your fuel tankandcarburetor withoutcausing functional problems will vary withsuch factors as gasoline blend, your storagetemperatures, andwhether thefuel tankis partially or completely filled. The air in apartially filled fuel tankpromotes fuel deterioration.Very warmstoragetemperaturesaccelerate fueldeterioration.Fuel problemmay occur within a few months, or even less if thegasoline wasnot fresh when youfilled the fuel tank.

Fuel system damageor engine performance problems resultingfromneglectedstoragepreparation are notcoveredunder theDistributor’s Limited Warranty .

You can extend fuel storage lifebyadding a gasoline stabilizerthat is formulated for thatpurpose, or youcan avoid fueldeterioration problems by draining the fuel tankand carburetor.

When adding a gasolinestabilizer, fill the fuel tankwith freshgasoline. If only partially filled,air in thetank will promote fueldeterioration duringstorage. If youkeepa container of gasolinefor refueling, besure thatit contains only fresh gasoline.

Add gasoline stabilizer following themanufacturer’s instructio

After adding a gasoline stabilizer, runthe engine outdoors forminutes to besure thattreated gasoline has replaced theuntreated gasoline in thecarburetor.

Stopthe engine.

Thesparkarrester may bestandard or anoptional part, dependingon theengine type. In some areas, it is illegal to operate anenginewithouta sparkarrester. Checklocal laws and regulations. A sparkarrester is availablefromauthorizedHondaservicingdealers.

Thesparkarrester mustbeservicedevery 100hours to keep itfunctioning as designed.

If theengine has been running, themuffler will behot. Allow it tocool beforeservicing the sparkarrester.

Removethetwo 8mmnutsand removethemuffler from thecylinder.

Standard idle speed:

Turn the throttlestop screw toobtain the standard idlespeed.

Movethe throttle lever to itsminimum position.

Start the engine outdoors, andallow it to warmupto operatingtemperature.

Install thesparkarrester, muffler protector,exhaustdeflectorand muffler in the reverseorderof disassembly.

Use a brush to remove carbondeposits fromthe sparkarresterscreen. Becareful notto damagethe screen. Replacethe sparkarrester if ithas breaks or holes.

Removethe4mmscrew from the sparkarrester, and remove

the sparkarrester fromthe muffler.

If your enginewill bestored with gasoline in thefuel tankandcarburetor, it is important to reduce the hazard of gasoline vaporignition.Selecta well-ventilatedstorageareaaway fromanyappliance thatoperates witha flame, such as a furnace, waterheater, or clothes dryer.Also avoidany areawith a spark-producing electric motor, or wherepower tools are operated.

If possible, avoid storageareas withhigh humidity, becausethatpromotes rust and corrosion.

Keepthe engine level in storage. Tilting can cause fuel or oilleakage.

With the engine and exhaustsystem cool, cover the engine tokeep out dust. A hot engineand exhaust systemcan ignite or mesome materials.Do not use sheet plastic asa dustcover. Anonporous coverwill trapmoisturearound the engine,promotinrust and corrosion.

Gasolineis highly flammable and explosive, and youcan beburned or seriously injured when handlingfuel.

Stopengine and keep heat, sparks, and flameaway.

Wipeup spills immediately.

Place anapprovedgasoline container below the carburetor, anduse a funnel to avoidspilling fuel.

If the cylinderwas coated withoil duringstoragepreparation, theengine will smoke brieflyatstartup.This is normal.

Check your engine as described in theBEFO RE OPERATION

CHECKS section of this manual (see page ).

If equipped witha battery for electric starter types, rechargethebattery oncea month while the engine is in storage. Thiswill help to extend the service lifeof the battery.

Handle fuel onlyoutdoors.

Remove the carburetordrain boltand gasket. Remove thesedimentcup and O-ring, then move the fuel valve lever to theON position.

After all the fuel has drained into the container, reinstall thedrain bolt, gasket, sediment cup and O-ring. Tighten the drainboltand sedimentcup securely.

Change the engine oil (see page ).

Poura tablespoon 5 10cm (5 10 cc) of clean engine oil intothecylinder.

Pull thestarter rope several times to distribute theoil in thecylinder.

Reinstall the sparkplug.

Pull thestarter rope slowly until resistanceis feltand the notchon thestarterpulley aligns with theholeatthetop of the recoilstarter cover.This will close the valves so moisturecannotenterthe engine cylinder. Return the starter rope gently.

Remove the sparkplug (see page ). If theenginehasbeenrunning,allow it tocool forat least15

minutes beforeloading the engine-powered equipmenton thetransportvehicle.A hotengine and exhaustsystem can burn youand can ignitesomematerials.

If the fuel was drained during storagepreparation, fill the tankwfresh gasoline. If you keep a container of gasolinefor refueling,bsure it contains only fresh gasoline.Gasolineoxidizesanddeteriorates over time, causing hardstarting.

Keep the engine level when transporting to reducethe possibilityof fuel leakage.Turn thefuel valveto theOFFposition (seepage ).

Emission Control System Information

Source of Emissions

Tampering and Altering

Problems That May Affect Emissions

Replacement Parts

Maintenance

The U.S., California Clean Air Acts and Environment Canada

Thecombustion process produces carbon monoxide,oxides of nitrogen, and hydrocarbons.Control of hydrocarbons and oxidesof nitrogen is very important because, under certainconditions,they react to formphotochemical smogwhen subjected tosunlight. Carbon monoxidedoesnot react in the sameway,but iis toxic.

Hondautilizes lean carburetorsettings and other systems toreducethe emissions of carbonmonoxide,oxides of nitrogen, anhydrocarbons.

EPA, California and Canadian regulations requireallmanufacturers to furnishwritten instructions describing theoperation and maintenanceof emissioncontrol systems.

Thefollowing instructions and procedures mustbefollowed inorder tokeep the emissions from your Honda engine withintheemissionstandards.

Tampering withor altering the emissioncontrol system may

increase emissions beyond the legal limit. Amongthoseacts thaconstitute tampering are:

Removal or alterationof any partof the intake, fuel, or exhaustsystems.Alteringor defeating the governor linkage or speed-adjustingmechanism to causethe engine to operateoutsideitsdesignparameters.

If you are aware of any of thefollowingsymptoms, haveyourengine inspected and repaired by your servicingdealer.

Hard starting or stalling after starting.

Rough idle.Misfiring or backfiring under load.Afterburning (backfiring).Blackexhaustsmoke or high fuel consumption.

Theemissioncontrol systems on your Hondaengine weredesigned, built,and certified to conformwithEPA, California andCanadian emissionregulations. We recommendthe useof genuineHonda parts whenever you have maintenancedone. Theseoriginal-designreplacementparts are manufactured to thesamestandards as the original parts, so you can beconfidentof theirperformance.Theuseof replacementparts thatare notof toriginal designand quality may impair the effectiveness of your

emissioncontrol system.

A manufacturer of anaftermarketpart assumesthe responsibilitthatthe partwill notadversely affectemissionperformance.Themanufacturer or rebuilder of the partmust certify thatuseof thepartwill not result in a failureof theengine to comply withemissionregulations.

Follow the maintenancescheduleon page . Remember thatthischedule is based on theassumption that your machine will beused for itsdesignedpurpose.Sustainedhigh-loador high-temperatureoperation, or usein unusuallywetor dusty conditiowill requiremore frequent service.

When the carburetor has been modified for high altitude operation,

the air-fuel mixture will be too lean for low altitude use. Operation at altitudes below 1,500meters (5,000 feet) with a modified

carburetor may cause the engine to overheat and result in serious

engine damage. For use at low altitudes, have your servicing dealer return the carburetor to original factory specifications.

Even withcarburetormodification,engine horsepower willdecrease about 3.5%for each 300-meter (1,000-foot) increaseinaltitude. Theeffect of altitudeon horsepowerwill begreater thanthis if no carburetor modification is made.

High altitudeperformance can be improvedbyspecificmodifications to the carburetor. If youalways operateyour engineataltitudes above 1,500 meters (5,000feet), have your servicingdealer perform this carburetormodification.Thisengine,whenoperatedathigh altitudewith the carburetormodifications forhigh altitudeuse, will meeteachemissionstandard throughoutitsuseful life.

Pour la sécuritéet la longévité de l’équipement, il est important de

consacrer quelques instants à vérifier l’état du moteur avantl’utilisation.

Corriger tout problème constaté ou confier cette opération au

concessionnaire avant l’utilisation.

Toujours vérifier les points suivants avant de mettre le moteur en marche

Vérifier s’il n’y a pas de traces de fuites d’huile ou d’essence autour ou

sous le moteur.

Enlever toute saleté ou débris excessifs, tout particulièrement autour d

silencieux et du lanceur.

Vérifier s’il n’y a pas de signes de dommages.

S’assurer que tous les protecteurs et couvercles sont en place et que

tous les écrous, boulons etvis sont serrés.

Vérifier le niveau de carburant (voir page ). En démarrant avec un

réservoir de carburant plein, on évitera ou réduira les interruptions de

service pour faire le plein.

Un entretien incorrect de ce moteur ou l’absence de

correction d’un problème avantl’utilisation peut provoquer

une anomalie susceptible d’entraîner des blessures graves

ou mortelles.

Toujours effectuer les contrôles avant l’utilisation avant

chaque utilisation et corriger tout problème.

Avant de commencer les contrôles avant l’utilisation, s’assurer que le

moteur est à l’horizontale et quel’interrupteur du moteur se trouve sur la

position ARRET.

Pour les précautions et procédures à observer avant le démarrage du

moteur, consulter les instructions accompagnantl’équipement

commandé par ce moteur.

Vérifier l’équipement commandé par ce moteur.

Vérifier l’élémentde filtre à air (voir page ). Un élémentde filtre à ai

sale limite le passage d’air vers le carburateur, ce qui diminue les

performances du moteur.

Vérifier le niveau d’huile du carter de réducteur sur les types applicabl(voir page ). L’huile est essentielle au bon fonctionnement et à la

longévité du carter de réducteur.

Le système Oil Alert (types applicables) arrête automatiquement le

moteur avant que le niveau d’huile ne descende au-dessous du seuil d

sécurité. Toutefois, pour éviter l’inconvénientd’un arrêt imprévu,

toujours vérifier le niveau d’huile du moteur avant le démarrage.

Vérifier le niveau d’huile du moteur (voir page ). L’utilisation du

moteur avec un niveau d’huile insuffisant peut provoquer des

dommages au moteur.

Enfoncer le bouton du protecteur de

circuitpour le réenclencher.

L’indicateur vert à l’intérieur du

protecteur de circuit sort pour indiquer

que le circuita été coupé. Dans un tel

cas, rechercher la cause du problème

et la corriger avant de réenclencher le

protecteur de circuit.

Le protecteur de circuit protège le

circuitde charge de la batterie. Un

court-circuit ou une batterie connectés

avec une polarité inversée déclenche

le coupe-circuit.

Si le moteur s’arrête et ne redémarre pas, vérifier le niveau d’huile du

moteur (voir page ) avantde rechercher l’originedu problème dans

d’autres parties.

Le système Oil Alert protège le moteur contre les dommages dus au

manque d’huile dans le carter moteur. Avant quele niveau d’huile du

carter moteur ne descende au-dessous du seuil de sécurité, le système Oil

Alert arrête automatiquement le moteur (l’interrupteur du moteur reste sur

la position MA RCHE).

TYPE STANDARD

TUYAU RENIFLARDTUYAU RENIFLARD

CLIP DE TUYAU

TYPE A CARBURATEUR AEVENT INTERNE

Un entretien incorrect ou l’absence de correction d’un

problème avantl’utilisation peut provoquer une anomalie

susceptible d’entraîner des blessures graves ou mortelles.

Toujours observer les recommandations etprogrammes de

contrôle etd’entretien figurant dans ce manuel.

Le programme d’entretien s’applique à des conditions d’utilisation

normales. Si l’on utilise le moteur dans des conditions sévères telles qu’un

fonctionnement prolongé sous unecharge élevée ou par haute

température, ou dans des conditions anormalement humides ou

poussiéreuses, demander au concessionnaire des recommandations pour

des besoins et un usage particuliers.

Certaines des consignes de sécuritéles plus importantes sont indiquées ci-

dessous. Il ne nous est toutefois pas possible de vous avertir de tous les

dangers imaginables que vous pouvezcourir en exécutantl’entretien.

Vous êtes seul juge de décider si vous devez ou non effectuer un travail

donné.

Pour permettre d’entretenir correctement le moteur, on trouvera aux pages

suivantes un programme d’entretien, des procédures de contrôle de

routine et des procédures d’entretien simples pouvant être effectuées avec

des outils à main de base. D’autres opérations d’entretien plus difficiles ou

demandant des outils spéciaux seront mieux exécutées par des

professionnels etdevront normalement être confiées à un technicien

Honda ou à un autre mécanicien qualifié.

En n’observant pas correctement les instructions et

précautions d’entretien, on s’expose à de graves blessures

ou à un danger demort.

Toujours observer les procédures et précautions de ce

manuel.

Avant de commencer un entretien ou une réparation, s’assurer que le

moteur est arrêté. Ceci éliminera plusieurs risques potentiels:

Pour diminuer les risques d’incendieou d’explosion, être prudent

lorsqu’on travaille à proximité de l’essence. Pour le nettoyage des pièces,

utiliser uniquement un solvant ininflammable et non de l’essence. Ne

pas approcher de cigarettes, étincelles ou flammes des pièces dusystème d’alimentation en carburant.

Lire les instructions avantde commencer et s’assurer que l’on dispose

de l’outillage etdes compétences nécessaires pour effectuer le travail en

sécurité.

Ne faire tourner le moteur que si cela est indiqué dans les instructions.

Attendre que le moteur etle système d’échappement se soient

refroidis avant de les toucher.

Avant d’utiliser le moteur, s’assurer que l’aération est suffisante.

L’inobservation de ce programme d’entretien peut entraîner desproblèmes non couverts par la garantie.

Pour une utilisation commerciale, consigner le nombre d’heures de

service afin de déterminer la périodicité d’entretien appropriée.

Confier l’entretien de ces points au concessionnaire à moins que l’o

ne dispose des outils appropriés et ne soit mécaniquement compéte

Pour les procédures d’entretien, voir le manuel d’atelier Honda.

En cas d’utilisation dans des endroits poussiéreux, augmenter la

fréquence d’entretien.

Ne remplacer que le type à élément en papier.

Type cyclonique tous les 2 ans ou 600 heures.

Carburateur à évent interne avec double élément seulement.

Type cyclonique tous les 6 mois ou 150heures.

Ne pas oublier que c’est le concessionnaire Honda agréé qui connaît le

mieux le moteur etqu’il estparfaitement outillé pour son entretien et sa

réparation.

Pour la meilleure qualité etfiabilité, n’utiliser que des pièces Honda

d’origine neuves ou leur équivalent pour la réparation etle remplacemen

Un bon entretien est essentiel pour un fonctionnement sûr, économique et

sans problème. Il contribue également à réduire la pollution.

moteur vient de tourner, le laisser d’abord se refroidir. Ne jamais fairele

plein à l’intérieur d’un bâtiment où des vapeurs d’essencepourraient

atteindre des flammes ou des étincelles.

On peut utiliser une essencesans plomb ordinaire ne contenant pas plus

de 10% d’éthanol (E10)ou de 5%de méthanol en volume. Le méthanol doit

contenir des cosolvants et des inhibiteurs de corrosion. L’utilisation de

carburants ayant une teneur en éthanol ou méthanol supérieure à celle

indiquée ci-dessus peut occasionner des problèmes de démarrage et/ou

performances. Elle peut également endommager les pièces métalliques,

en caoutchouc eten plastique du système d’alimentation en carburant. Les

dommages au moteur ou problèmes de performance résultant de

l’utilisation d’un carburant avec des pourcentages d’éthanol ou méthanol

supérieurs à ceux qui sont indiqués ci-dessus ne sont pas couverts par la

garantie.

Faire le plein avec précaution pour éviter de renverser du carburant. N

pas remplir le réservoir de carburant complètement. Remplir le réserv

jusqu’àenviron 25 mm du haut du réservoir pour permettre la dilatatio

du carburant. Dans certaines conditions d’utilisation, il peut être

nécessaire de baisser le niveau du carburant. Après avoir fait le plein,

resserrer le bouchon de remplissagede carburant à fond.

Essuyer immédiatement tout

carburant renversé.

Ne faire le plein qu’à l’extérieur.
