FUEL HANDLING

General

WARNING! Running an engine in a
confined or badly ventilated area can

!

result in death due to asphyxiation or
carbon monoxide poisoning. Use fans to
ensure proper air circulation when
working in trenches or ditches deeper
than one meter.

Fuel and fuel fumes are flammable and
can cause serious injury when inhaled or
allowed to come in contact with the skin.
For this reason observe caution when
handling fuel and make sure there is
adequate ventilation.

The exhaust fumes from the engine are
hot and may contain sparks which can
start a fire. Never start the machine
indoors or near combustible material!

Do not smoke and do not place any hot
objects in the vicinity of fuel.

Fuel

NOTICE! The machine is equipped with a two-stroke
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.

Petrol

• Use good quality unleaded or leaded petrol.

• The lowest octane recommended is 90 (RON). If you
run the engine on a lower octane grade than 90 so­called knocking can occur. This gives rise to a high
engine temperature, which can result in serious
engine damage.

• When working at continuous high revs a higher octane
rating is recommended.

Environment fuel

HUSQVARNA recommends the use of alkylate fuel,
either Aspen two-stroke fuel or environmental fuel for
four-stroke engines blended with two-stroke oil as set out
below. Note that carburettor adjustment may be
necessary when changing the type of fuel (see the
instructions under the heading Carburettor).

Ethanol blended fuel, E10 may be used (max 10%
ethanol blend). Using ethanol blends higher than E10 will
create lean running condition which can cause engine
damage.

Two-stroke oil

• For best results and performance use HUSQVARNA
two-stroke engine oil, which is specially formulated for
our air-cooled two-stroke engines.

• Never use two-stroke oil intended for water-cooled
engines, sometimes referred to as outboard oil (rated
TCW).

• Never use oil intended for four-stroke engines.

Mixing

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

• 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.

• Mix (shake) the fuel mixture thoroughly before filling
the machine’s fuel tank.

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

Mixing ratio

• 1:50 (2%) with HUSQVARNA two-stroke oil or
equivalent.

Petrol, litre Two-stroke oil, litre

2% (1:50)

5 0,10
10 0,20

• 1:33 (3%) with oils class JASO FB or ISO EGB
formulated for air-cooled, two-stroke engines or mix
as per recommendation from the oil manufacturer.

Fueling

!

FUEL HANDLING

WARNING! Taking the following
precautions, 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 refuelling. The
engine should be switched off, and the
stop switch in STOP position.

When refuelling, open the fuel cap slowly
so that any excess pressure is released
gently.

Clean the area around the fuel cap.

Tighten the fuel cap carefully after
refuelling.

If the cap is not properly tightened the
cap might vibrate lose and fuel may
escape from the fuel tank creating a fire
hazard.

Move the machine at least 3 m from the
refuelling point before starting it.

Never start the machine:

• If you have spilled fuel or engine oil on the machine.
Wipe off the spill and allow the remaining fuel to
evaporate.

• If you have spilled fuel on yourself or your clothes,
change your clothes. Wash any part of your body that
has come in contact with fuel. Use soap and water.

• If the machine is leaking fuel. Check regularly for
leaks from the fuel cap and fuel lines.

• Unless the fuel cap is securely tightened after
refueling.

Transport and storage

• Store and transport the machine and fuel so that there
is no risk of any leakage or fumes coming into contact
with sparks or open flames, for example, from
electrical machinery, electric motors, electrical relays/
switches or boilers.

• When storing and transporting fuel always use
approved containers intended for this purpose.

Long-term storage

• When storing the machine for long periods the fuel
tank must be emptied. Contact your local petrol
station to find out where to dispose of excess fuel.

This can damage the machine.

WARNING! When the engine is running
the exhaust contains chemicals such as
unburned hydrocarbons and carbon
monoxide. The content of the exhaust
fumes is known to cause respiratory
problems, cancer, birth defects or other
reproductive harm.

Carbon monoxide is colorless and
tasteless and is always present in
exhaust fumes. The onset of carbon
monoxide poisoning is distinguished by
a slight dizziness which may or may not
be recognized by the victim. A person
may collapse and lapse into
unconsciousness with no warning if the
concentration of carbon monoxide is
sufficiently high. Since carbon monoxide
is colorless and odorless, its presence
can not be detected. Any time exhaust
odors are noticed, carbon monoxide is
present. Never use a petrol powered
power cutter indoors or in trenches more
than 3 foot (1 meter) deep or in other
areas with poor ventilation. Ensure
proper ventilation when working in
trenches or other confined areas.

Stopping

CAUTION! The cutting blade continues to

ÉQUIPEMENT DE SÉCURITÉ DE LA MACHINE

Généralités

AVERTISSEMENT! Ne jamais utiliser une
machine dont les équipements de

!

sécurité sont défectueux. Si les
contrôles ne donnent pas de résultat
positif, confier la machine à un atelier
spécialisé.

Le moteur doit être éteint et le bouton
d'arrêt en position STOP.

Ce chapitre présente les équipements de sécurité de la
machine, leur fonction, comment les utiliser et les
maintenir en bon état.

Blocage de l’accélération

Le blocage de l'accélération est conçu pour empêcher
toute activation involontaire de la commande de
l'accélération. Lorsque le blocage (A) est enfoncé, la
commande de l'accélération est embrayée (B).

Le blocage reste enfoncé tant que la commande
d’accélération est sollicitée. Lorsque la poignée est
relâchée, la gâchette d’accélération et le blocage de
l’accélération retrouvent leurs positions initiales. Ceci
s’effectue à l’aide de deux systèmes de retour par
ressorts, indépendants l’un de l’autre. En position initiale,
la gâchette d’accélération est automatiquement bloquée
au régime de ralenti.

Vérification du blocage de la commande
d'accélération

• Vérifier d’abord que la commande de l’accélération
est bloquée en position de ralenti quand le blocage de
l’accélération est en position initiale.

• Vérifier que le blocage de l’accélération, la
commande d’accélération et leurs ressorts de rappel
fonctionnent correctement.

• Démarrer la découpeuse et donner les pleins gaz.
Relâcher la commande de l'accélération et contrôler
que le disque découpeur s'arrête et qu'il demeure
immobile. Si le disque découpeur tourne quand la
commande est en position de ralenti, il convient de
contrôler le réglage du ralenti du carburateur. Voir les
instructions au chapitre «

Entretien ».

Bouton d’arrêt

Le bouton d’arrêt est utilisé pour arrêter le moteur.

Vérification du bouton d'arrêt

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

• Appuyer sur le blocage de l’accélération et vérifier
qu’il revient de lui-même en position initiale quand il
est relâché.

AVERTISSEMENT! N'utilisez jamais une
machine sans silencieux ou avec un
silencieux défectueux. Si le silencieux
est défectueux, le niveau sonore et le
risque d’incendie augmentent
considérablement. Veillez à disposer des
outils nécessaires à l’extinction d’un feu.

Le silencieux devient très chaud pendant
et après l’utilisation, ainsi qu’au cours du
fonctionnement au ralenti. Soyez attentif
au risque d’incendie, surtout à proximité
de produits inflammables et/ou en
présence de gaz.

Veillez à disposer des outils nécessaires
à l’extinction d’un feu.

Le silencieux est conçu pour réduire au maximum le
niveau sonore et détourner les gaz d’échappement loin
de l’utilisateur.

Contrôle du silencieux

Contrôler régulièrement que le silencieux est entier et
qu’il est attaché correctement.

• Contrôler régulièrement les éléments anti-vibrations
afin de détecter toute éventuelle fissure ou
déformation. Les remplacer s'ils sont endommagés.

• S’assurer de la bonne fixation des éléments anti­vibrations entre l’unité moteur et l’ensemble poignée.

Équipement de protection

Généralités

Ne jamais utiliser une machine s’il n’est pas possible
d’appeler au secours en cas d’accident.

Équipement de protection personnelle

Un équipement de protection personnelle homologué doit
impérativement être utilisé lors de tout travail avec la
machine. L’équipement de protection personnelle
n’élimine pas les risques mais réduit la gravité des
blessures en cas d’accident. Demander conseil au
concessionnaire afin de choisir un équipement adéquat.

AVERTISSEMENT! L’utilisation de
produits tels que des ciseaux, des

!

disques, des forets, des disques fins ou
des formes peut générer de la poussière
et des vapeurs pouvant contenir des
substances chimiques toxiques. Vérifiez
la composition du matériel avec lequel
vous travaillez et portez un masque
respiratoire adapté.

Une exposition prolongée au bruit risque
de causer des lésions auditives
permanentes. Toujours utiliser des
protecteurs d'oreille agréés. Soyez
toujours attentifs aux signaux d’alerte ou
aux appels en portant des protège­oreilles. Enlevez-les sitôt le moteur
arrêté.

Autre équipement de protection

REMARQUE ! Lorsque vous travaillez
avec la machine, des étincelles peuvent
se former et mettre le feu. Gardez
toujours à portée de main les outils
nécessaires à l'extinction d'un feu.

• Extincteur

• Trousse de premiers secours

Toujours utiliser:

• Casque de protection homologué

• Protecteur d’oreilles

• Des protège-yeux homologués. L’usage d’une visière
doit toujours s’accompagner du port de lunettes de
protection homologuées. Par lunettes de protection
homologuées, on entend celles qui sont en conformité
avec les normes ANSI Z87.1 (États-Unis) ou EN 166
(pays de l’UE). La visière doit être conforme à la
norme EN 1731.

• Masque respiratoire

• Gants solides permettant une prise sûre.

• Vêtements confortables, robustes et serrés qui
permettent une liberté totale de mouvement. La
découpe crée des étincelles qui peuvent enflammer
les vêtements. Husqvarna vous recommande de
porter du coton ignifugé ou du denim épais. Ne portez
pas de vêtements composés de matières comme le
nylon, le polyester ou la rayonne. Si elles
s’enflamment, ces matières peuvent fondre et adhérer
à la peau. Ne portez pas de shorts

• Bottes avec coquille en acier et semelle
antidérapante.

MANIPULATION DU CARBURANT

Généralités

AVERTISSEMENT! Faire tourner un
moteur dans un local fermé ou mal aéré

!

peut causer la mort par asphyxie ou
empoisonnement au monoxyde de
carbone. Utilisez des ventilateurs pour
assurer une bonne circulation de l'air
lorsque vous travaillez dans des
tranchés ou des fossés d'une profondeur
supérieure à un mètre.

Le carburant et les vapeurs de carburant
sont inflammables et peuvent causer des
blessures graves en cas d’inhalation ou
de contact avec la peau. Il convient donc
d’observer la plus grande prudence lors
de la manipulation du carburant et de
veiller à disposer d’une bonne aération.

Les gaz d’échappement du moteur sont
très chauds et peuvent contenir des
étincelles pouvant provoquer un
incendie. Par conséquent, ne jamais
démarrer la machine dans un local clos
ou à proximité de matériaux
inflammables!

Ne fumez jamais ni ne placez d’objet
chaud à proximité du carburant.

Carburant

ATTENTION ! La machine est équipée d’un moteur
deux temps et doit toujours être alimentée avec un
mélange d'essence et d’huile deux temps. Afin d’obtenir
un mélange approprié, il est important de mesurer avec
précision la quantité d’huile à mélanger. Pour le
mélange de petites quantités de carburant, la moindre
erreur peut sérieusement affecter le rapport du
mélange.

Essence

• Utiliser une essence de qualité, avec ou sans plomb.

• Le taux d’octane minimum recommandé est de 90
(RON). Si l’on fait tourner le moteur avec une essence
d’un taux d’octane inférieur à 90, un cognement
risque de se produire, résultant en une augmentation
de la température du moteur pouvant causer de
graves avaries du moteur.

• Si on travaille en permanence à des régimes élevés,
il est conseillé d’utiliser un carburant d’un indice
d’octane supérieur.

Carburant écologique

HUSQVARNA recommande l'utilisation d'une essence
écologique (dite essence alkylat), soit une essence deux
temps prémélangée Aspen, soit une essence écologique
pour moteurs quatre temps mélangée avec de l'huile deux

temps selon les instructions ci-dessous. Noter qu'il peut
être nécessaire de procéder à un réglage du carburateur
lors du changement de type d'essence (voir les
instructions à la section Carburateur).

Possibilité d’utiliser du carburant mélangé à base
d’éthanol, E10 (la teneur en éthanol ne doit pas dépasser
10 %). L’utilisation de carburants mélangés contenant
plus d’éthanol que l’E10 perturbe le fonctionnement de la
machine et risque d’endommager le moteur.

Huile deux temps

• Pour obtenir un fonctionnement et des résultats
optimaux, utiliser une huile moteur deux temps
HUSQVARNA fabriquée spécialement pour nos
moteurs deux temps à refroidissement à air.

• Ne jamais utiliser d’huile deux temps pour moteurs
hors-bord refroidis par eau, appelée huile outboard
(désignation TCW).
