GENERAL SAFETY RULES
WARNING:
READ AND UNDERSTAND ALL INSTRUCTIONS. Failure
to follow all instructions may result in electric shock, fire
and/or serious personal injury.
READ ALL INSTRUCTIONS
For safe operation, read and understand all instructions
before using this product. Follow all safety instructions.
Failure to follow all safety instructions, can result in serious
personal injury.
Do not allow children or untrained individuals to use this
unit.
Do not start or operate the engine in a confined space,
building,near openwindows, orin otherunventilated space
where dangerous carbon monoxide fumes can collect.
Carbon monoxide, a colorless, odorless, and extremely
dangerous gas, can cause unconsciousness or death.
Clear the work area before each use. Remove all objects
such as rocks, broken glass, nails, wire, or loose string
which can be thrown or become entangled in the cutting
line or blade.
Always wear eye protection with side shields marked to
comply with ANSI Z87.1. Failure to do so could result in
objects being thrown into your eyes, resulting in possible
serious injury.
Wear heavy, long pants, long sleeves, boots, and gloves.
Do not wear loose fitting clothing, short pants, sandals, or
go barefoot. Do not wear jewelry of any kind.
Heavy protective clothing may increase operator fatigue,
which could lead to heat stroke. During weather that is
hot and humid, heavy work should be scheduled for early
morning or late afternoon hours when temperatures are
cooler.
Product users on United States Forest Service land, and in
some states, must comply with fire prevention regulations.
This product is equipped with a spark arrestor; however,
otheruser requirementsmayapply. Checkwith yourfederal,
state, or local authorities.
Never operate this unit on the operator’s left side.
Secure long hair above shoulder level to prevent
entanglement in moving parts.
Keep all bystanders, children, and pets at least
50 ft. away. Bystanders should be encouraged to wear
eye protection. If you are approached, stop the engine and
cutting attachment. In the case of bladed units, there is the
added risk of injury to bystanders from being struck with
the moving blade in the event of a blade thrust or other
unexpected reaction of the blade or saw chain.
Do not operate this unit when you are tired, ill, upset, or
under the influence of alcohol, drugs, or medication.
Do not operate in poor lighting.
Keep firm footing and balance. Do not overreach.
Overreaching can result in loss of balance or exposure to
hot surfaces.
Do not use on a ladder or unstable support. Stable footing
on a solid surface enables better control of the unit in
unexpected situations.
Keep all parts of your body away from any moving part.
Toavoid hotsurfaces, neveroperate the unit with thebottom
of the engine above waist level.
Do not touch area around the muffler or cylinder of the unit,
these parts get hot from operation.
Always stop the engine and remove the spark plug wire
before making any adjustments or repairs except for
carburetor adjustments.
Inspect the unit before each use for loose fasteners, fuel
leaks, etc. Replace any damaged parts before use.
Never use blades, flailing devices, wire, or rope on trimmer
attachment. Never use flailing devices, wire, or rope on any
attachment.
The cutting attachment should never rotate at idle during
normaluse. Thecutting attachmentmay rotateat idleduring
carburetor adjustments.
It has been reported that vibrations from hand-held tools
may contribute to a condition called Raynaud’s Syndrome
in certain individuals. Symptoms may include tingling,
numbness, and blanching of the fingers, usually apparent
upon exposure to cold. Hereditary factors, exposure to
cold and dampness, diet, smoking, and work practices
are all thought to contribute to the development of these
symptoms. It is presently unknown what, if any, vibrations
or extent of exposure may contribute to thecondition. There
are measures that can be taken by the operator to possibly
reduce the effects of vibration:
a) Keep your body warm in cold weather. When operating
the unit wear gloves to keep hands and wrists warm. It is
reported that cold weather is a major factor contributing
to Raynaud’s Syndrome.
b) After each period of operation, exercise to increase
blood circulation.
c) Take frequent work breaks. Limit the amount of
exposure per day.
d) Keep the tool well maintained, fasteners tightened, and
worn parts replaced.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician about
these symptoms.
Store fuel in a container approved for gasoline.
Fuel and refuel outdoors where there are no sparks or
flames. Wipe up any fuel spillage. Move 30 ft. away from
refueling site before starting engine. Slowly remove the fuel
cap after stopping engine. Do not smoke when refueling.
Stop the engine and allow to cool before refueling or storing
the unit.

SPECIFIC SAFETY RULES
This product is intended for infrequent use by homeown-
ers and other occasional users for such general applica-
tions as trimming light and heavy vegetation, etc. It is not
intended for prolonged use. Prolonged periods of opera-
tion can cause circulatory problems in the user’s hands
due to vibration. For such use, it may be appropriate to
use a product having an anti-vibration feature.
SPECIFIC SAFETY RULES FOR TRIMMER USE
Inspect before use. Replace damaged parts. Make sure
fasteners are in place and secure. Check for fuel leaks.
Replace string head if cracked, chipped, or damaged
in any way. Be sure the string head or blade is properly
installedand securelyfastened.Failureto do socan cause
serious injury.
Make sure all guards, straps, deflectors, and handles are
properly and securely attached.
Use only the manufacturer’s replacement line in the
cutting head. Do not use any other cutting attachment.
To install any other brand of replacement line or cutting
head to this string trimmer can result in serious personal
injury. Never use, for example, wire or wire-rope, which
can break off and become a dangerous projectile.
Never operate unit without the grass deflector in place
and in good condition.
Never use blades, flailing devices, wire, or rope on trimmer
attachment.
Maintain a firm grip on both handles while trimming. Keep
string head below waist level. Never cut with the string
head located over 30 in. or more above the ground.
SPECIFIC SAFETY RULES FOR BRUSH
CUTTER AND BLADE USE
Brush cutter blades coast after throttle trigger is released
or engine is stopped. Keep the rotating blade in thicker
weeds or pulpy stalks until the blade completely stops.
Do not operate the brush cutter unless the brush cutter
guard is firmly secured in place and in good condition.
Use heavy gloves when operating the brush cutter and
when installing or removing blades.
Always stop the engine and remove the spark plug wire
before attempting to remove any obstruction caught or
jammed in the blade or before removing and installing
the blade.
Do not attempt to touch or stop the blade when it is
rotating.
A coasting blade can cause injury while it continues
to spin after the engine is stopped or throttle trigger
released. Maintain proper control until the blade has
completely stopped rotating.
Replace any blade that has been damaged. Always make
sure blade is installed correctly and securely fastened
before each use. Failure to do so can cause serious injury.
Use only the manufacturer’s replacement Tri-Arc®blade
intended for use on this brush cutter. Do not use any other
blade. To install any other brand blade or cutting head to
this brush cutter can result in serious personal injury.
The Tri-Arc®blade is suited for cutting thicker weeds or
pulpy stalks only. Do not use for any other purpose. Never
use the Tri-Arc®blade to cut woody brush.
Exercise extreme caution when using the blade with this
unit. Blade thrust is the reaction that may occur when
the spinning blade contacts anything it cannot cut. This
contact may cause the blade to stop for an instant, and
suddenly “thrust” the unit away from the object that was
hit. This reaction can be violent enough to cause the
operator to lose control of the unit. Blade thrust can occur
without warning if the blade snags, stalls, or binds. This is
more likely to occur in areas where it is difficult to see the
material being cut. For cutting ease and safety, approach
the weeds being cut from the right to the left. In the event
an unexpected object or woody stock is encountered,
this could minimize the blade thrust reaction.
Never cut any material over 1/2 in. diameter.
Always wear the shoulder harness when using the brush
cutter and adjust to a comfortable operating position.
Maintain a firm grip on both handles while cutting with a
blade. Keep the blade away from your body and below
waist level.
Never use the brush cutter with the blade located 30 in.
or more above the ground level.
Save these instructions. Refer to them frequently and use
them to instruct others who may use this tool. If you loan
someone this tool, loan them these instructions also.
GENERAL SAFETY RULES
Allow the engine to cool; empty the fuel tank and secure
the unit from moving before transporting in a vehicle.
Wear your protective equipment and observe all safety
instructions. For units equipped with a clutch, be sure
the cutting attachment stops turning when the engine
idles. When the unit is turned off make sure the cutting
attachment has stopped before the unit is set down.

OPERATION

9 — English
OPERATION
BLADE THRUST
Exercise extreme caution when using a blade attachment
with this unit. Blade thrust is the reaction that may occur
when the spinning blade contacts anything it cannot cut.
This contact may cause the blade to stop for an instant, and
suddenly “thrust” the unit away from the object that was hit.
This reaction can be violent enough to cause the operator
to lose control of the unit. Blade thrust can occur without
warning if the blade snags, stalls, or binds. This is more likely
to occur in areas where it is difficult to see the material being
cut. For cutting ease and safety, approach the weeds being
cut with the brush cutter from the right to the left. In the event
an unexpected object or woody stock is encountered, this
practice could minimize the blade thrust reaction.

You can often make adjustments and repairs described
here. For other repairs, have the power head serviced by
an authorized service dealer.
IDLE SPEED ADJUSTMENT
See Figure 9.
WARNING:
The blade/cutting head will move when adjusting the
idle speed. Wear all protective clothing and keep all by-
standers, children, and pets at least 50 ft. away. Make
adjustments with the unit supported by hand so that the
blade/cutting head does not contact the ground or any
object. Keep all parts of your body away from the blade/
cutting head and muffler. Failure to follow these instruc-
tions could result in serious personal injury.
If the cutting attachment turns at idle, the idle speed screw
needs adjusting on the engine. Turn the idle speed screw
counterclockwise to reduce the idle RPM and stop the cut-
ting attachment movement. If the cutting attachment still
moves at idle speed, contact a service dealer for adjustment
and discontinue use until the repair is made.
WARNING:
The cutting attachment should never turn at idle. Turn
the idle speed screw counterclockwise to reduce the
idle RPM and stop the cutting attachment, or contact a
service dealer for adjustment and discontinue use until
the repair is made. Serious personal injury can result from
the cutting attachment turning at idle.
CLEANING THE AIR FILTER
See Figures 10 - 11.
For proper performance and long life, keep air filter screen
clean.
Remove the air filter cover. To remove, push up on the
latch at the bottom of the cover and gently pull the cover
up.
Remove the air filter.
Clean the foam filter element with warm soapy water.
Rinse and let dry.
NOTE: If the foam filter element is damaged, it should be
replaced.
Apply a light coat of engine oil to the foam filter element,
then squeeze it out.
Reinstall the air filter.
NOTE: Make sure the filter is seated properly inside the
cover. Installing the filter incorrectly will allow dirt to enter
the engine, causing rapid engine wear.
Replace the air filter cover by placing the slots on the air
filter cover over the tabs on the housing, then push the
cover down until it latches securely in place.
MAINTENANCE
FUEL CAP, TANK, AND LINES
WARNING:
Check for fuel leaks. A leaking fuel cap, tank, or lines
are a fire hazard and must be replaced immediately. If
you find any leaks, correct the problem before using the
product. Failure to do so could result in a fire that could
cause serious personal injury.
The fuel cap contains a non-serviceable filter and a check
valve. A clogged fuel filter will cause poor engine perfor-
mance. If performance improves when the fuel cap is loos-
ened, check valve may be faulty or filter clogged. Replace
fuel cap if required.
SPARK PLUG REPLACEMENT
This engine uses a Champion RY4C or equivalent spark plug
with .025 in. electrode gap. Use an exact replacement and
replace annually.
NOTICE:
Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the product.

toutes les instructions avant d’utiliser ce produit. Respecter
toutes les instructions de sécurité. Le non respect des
instructions de sécurité peut entraîner des blessures graves.
Ne pas laisser des enfants ou personnes n’ayant pas reçu une
formation adéquate utiliser cet outil.
Ne pas démarrer ou faire tourner le moteur dans un espace
confine, de bâtiment, à proximité des fenêtres ouverts, autre
ou des zones sans ventilation où des vapeurs toxiques de
monoxyde de carbone peuvent s’accumuler. Le monoxyde de
carbone, un gaz incolore, inodore et extrêmement toxique peut
causer une perte de conscience et être mortel.
Déblayer la zone de travail avant chaque utilisation. La
débarrasser de tous les objets tels que cailloux, verre brisé,
clous, fils métalliques, cordes, etc. risquant d’être projetés ou
de se prendre dans la ligne de coupe ou la lame.
Toujours porter une protection oculaire avec écrans latéraux
certifiée conforme à la norme ANSI Z87.1. Si cette précaution
n’est pas prise, des objets peuvent être projetés dans les yeux
et causer des lésions graves.
Porter des pantalons longs, manches longues, des chaussures
de travail et des gants épais. Ne pas porter de vêtements
amples, bijoux, shorts, sandales et ne pas travailler pieds nus.
Ne porter aucun bijou.
Le fait de porter des vêtements de protection lourds peut
augmenter la fatigue de l’utilisateur, ce qui pourrait entraîner
un coup de chaleur. Si le temps est chaud et humide, effectuer
les gros travaux le matin ou en fin d’après-midi, alors qu’il fait
plus frais.
Les produits utilisés sur les territoires des services forestiers
des États-Unis et de certains états doivent être conformes aux
réglementations de lutte contre l’incendie. Cet outil est doté
d’un pare-étincelles, toutefois, d’autres dispositifs peuvent être
requis. Consulter les autorités locales et gouvernementales.
Ne jamais utiliser cet outil en le tenant du côté gauche.
Attacher les cheveux longs pour les maintenir au-dessus des
épaules, afin qu’ils ne se prennent pas dans les pièces en
mouvement.
Garder les badauds, enfants et visiteurs à une distance de 15 m
(50 pi). Recommander aux personnes présente de porter une
protection oculaire. Si quelqu’un s’approche pendant l’utilisation
de l’outil, arrêter le moteur et l’accessoire de coupe. Le risque
de blessure est accru si on utilise un outil à lames. En effet, les
personnes se trouvant à proximité risquent d’être heurtés par
une lame en marche advenant qu’elle ricoche, ou à la suite de
toute autre réaction inattendue de la lame ou de la chaîne de
la scie.
Ne pas utiliser cet outil en état de fatigue, si l’on est souffrant
ou contrarié, ou sous l’influence de l’alcool, de drogues ou de
médicaments.
Ne pas travailler sous un éclairage insuffisant.
Se tenir bien campé et en équilibre. Ne pas travailler hors de
portée. Le travail hors de portée risque de faire perdre l’équilibre
ou de causer un contact avec les pièces brûlantes.
RÈGLES DE SÉCURITÉ GÉNÉRALES
Ne pas utiliser l’outil sur une échelle ou un support instable. Une
bonne tenue et un bon équilibre permettent de mieux contrôler
l’outil en cas de situation imprévue.
Garder toutes les parties du corps à l’écart des pièces en
mouvement.
Pour éviter le contact avec les parties brûlantes, ne jamais
travailler avec le bas du moteur au-dessus du niveau de la taille.
Ne pas toucher les alentours de l’échappement ou du cylindre,
qui deviennent brûlants pendant l’utilisation.
Toujours arrêter le moteur et débrancher le fil de la bougie avant
d’effectuer tout entretien ou réglage, à l’exception des réglages
du carburateur.
Inspecter l’outil avant chaque utilisation pour s’assurer qu’il
n’y a pas de pièces desserrées, de fuites ce carburant, etc.
Remplacer les pièces endommagées avant utilisation.
Ne jamais utiliser des lames, un dispositif fouetteur, un fil ou
une corde sur le accessoire taille-bordures. Ne jamais utiliser
des lames, un dispositif fouetteur, un fil ou une corde sur tout
autre accessoire.
Lors d’une utilisation normale, l’accessoire de coupe ne doit
jamais tourner au ralenti. La rotation au ralenti est toutefois
permise lors du réglage du carburateur.
Il a été rapporté que, chez certaines personnes, les vibrations
produites par les outils à main motorisés peuvent contribuer
au développement d’une affection appelée syndrome de
Raynaud. Les symptômes peuvent inclure des picotements,
l’insensibilisation et le blanchissement des doigts et sont
habituellement provoqués par l’exposition au froid. L’hérédité,
l’exposition au froid et à l’humidité, le régime alimentaire,
la fumée et les habitudes de travail sont tous des facteurs
considérés comme contribuant au développement de ces
symptômes. Il n’existe actuellement aucune preuve qu’un
certain type de vibration ou le degré d’exposition contribue
réellement au développement de cette affectation. Certaines
mesures, susceptibles de réduire les effets des vibrations,
peuvent être prises par l’opérateur :
a) Garder le corps au chaud par temps froid. Pendant
l’utilisation, porter des gants afin de tenir les mains et les
poignets au chaud. Il a été établi que le froid est l’une des
principales causes du symptôme de Raynaud.
b) Après chaque période d’utilisation, faire des exercices pour
accroître la circulation.
c) Faire des pauses fréquentes. Limiter la durée d’exposition
quotidienne.
d) Garder l’outil bien entretenu, toutes les pièces de boulonnerie
serrées et remplacer les pièces usées.
En cas d’apparition de l’un ou plusieurs des symptômes décrits
ci-dessus, cesser d’utiliser l’outil et consulter un médecin.
Conserver le carburant dans un bidon ou jerrican approuvé pour
l’essence.
Carburant et faire le plein à l’extérieur, loin de toute flamme ou
source d’étincelles. Essuyer tout carburant répandu. S’éloigner
de 9 m (30 pi) du point d’approvisionnement avant de lancer
le moteur. Desserrer le bouchon du réservoir de carburant
lentement une fois que le moteur est arrêté. Ne pas fumer
pendant le ravitaillement en carburant.
Arrêter le moteur et le laisser refroidir avant de faire le plein ou
de le remiser.
Pour le transport dans un véhicule, laisser le moteur refroidir,
vider le réservoir de carburant. et arrimer l’outil.

RÈGLES DE SÉCURITÉ PARTICULIÈRES
Ce produit est conçu pour les personnes qui prévoient
l’utiliser de manière peu fréquente pour des applications
générales par exemple, tailler la végétation faible et dense
etc.; l’outil peut également convenir à d’autres utilisateurs
occasionnels. Elle n’est pas conçue pour un usage prolongé.
Les périodes d’utilisation prolongée peuvent entraîner des
problèmes circulatoires dans les mains de l’opérateur, causés
par les vibrations. Pour ce type d’application, il peut être bon
d’utiliser une scie équipée d’un dispositif anti-vibrations.
RÈGLES DE SÉCURITÉ PARTICULIÈRES À
L’UTILISATION DU TAILLE-BORDURES
Inspecter l’outil avant chaque utilisation. Remplacer les
pièces endommagées. S’assurer que toutes les pièces de
boulonnerie sont en place et bien serrées. S’assurer de
l’absence de fuites de carburant.
Si la tête de coupe est fendue, brisée ou endommagée de
quelque façon que ce soit, la remplacer. S’assurer que la tête
de coupe ou la lame est correctement installée et solidement
assujettie. Ne pas prendre cette précaution peut entraîner
des risques de blessures graves.
S’assurer que tous les dispositifs de protection, sangles,
déflecteurs et poignées sont correctement installés et
solidement assujettis.
Utiliser exclusivement des lignes de coupe d’origine. Ne pas
utiliser d’autres accessoires de coupe. L’utilisation d’une tête
de coupe d’autre marque ou lignes de coupe d’autre origine
sur ce taille-bordures peut entraîner des blessures graves.
Par exemple, ne jamais utiliser de fil ou câble métallique qui
pourrait se briser et devenir un projectile dangereux.
Ne jamais utiliser l’appareil si le déflecteur d’herbe n’est pas
en place et en bon état.
Ne jamais utiliser de lames ou de dispositifs à fléau, fil et
cordes sur l’accessoire de taille-bordures.
Tenir fermement les deux poignées pendant le travail. Tenir
la tête de coupe au-dessous du niveau de la taille. Ne jamais
tailler avec la tête de coupe à plus de 762 mm (30 po) du sol.
RÈGLES DE SÉCURITÉ PARTICULIÈRES À
L’UTILISATION DE LA DÉBROUSSAILLEUSE
ET DE LA LAME
Les lames de la débroussailleuse poursuivent leur
mouvement après que la gâchette d’accélérateur ait été
relâchée ou que le moteur ait été mis à l’arrêt. Garder la
lame en rotation dans les herbes plus épaisses ou les tiges
pulpeuses jusqu’à ce qu’elle s’arrête complètement.
Ne pas utiliser la débroussailleuse si la garde de lame n’est
pas solidement assujettie et en bon état.
Porter des gants épais lors de l’utilisation de la débroussailleuse,
ainsi que du retrait et de l’installation des lames.
Toujours arrêter le moteur avant d’essayer de retirer des
objets pris dans la lame ou la bloquant et avant d’installer
ou retirer la lame.
Ne pas essayer de toucher ou d’arrêter la lame en rotation.
Une lame continuant de tourner au débrayé une fois que le
moteur est arrêté et la gâchette relâchée peut causer des
blessures. Garder le contrôle de l’outil jusqu’à ce que la lame
soit complètement immobilisée.
Toute lame endommagée doit être remplacée. S’assurer que
la lame est correctement installée et solidement assujettie
avant chaque utilisation. Ne pas prendre cette précaution
peut entraîner des risques de blessures graves.
Utiliser uniquement des lames Tri-Arc®d’origine conçues
pour cette débroussailleuse. Ne pas utiliser d’autres lames.
L’utilisation d’une tête de coupe d’autre marque sur ce taille-
bordures peut entraîner des blessures graves.
La lame Tri-Arc®est conçue pour couper des herbes
épaisses et plantes pulpeuses seulement. Ne pas l’utiliser
pour d’autres applications. Ne jamais utiliser la lame
Tri-Arc®pour couper de la végétation ligneuse.
Lorsqu’il est équipé d’une lame, utiliser cet outil avec la plus
extrême prudence. Un ricochet de lame peut se produire
lorsque celle-ci entre en contact avec un objet qu’elle ne
peut pas couper. Ce contact peut causer un bref blocage
de la lame, qui fait « ricocher » l’outil en direction opposée
de l’objet heurté. Cette réaction peut être assez violente
pour faire perdre le contrôle de l’outil. Un ricochet peut se
produire à tout instant si la lame est bloquée, stoppe ou se
coince. Ce problème est plus susceptible de se produire
dans les endroits où il n’est pas possible de voir le matériau
coupé. Pour faciliter la coupe et assurer la sécurité travailler
avec un mouvement de droite à gauche. Si la lame heurte
un obstacle imprévu ou du bois, ceci peut réduite la force
du ricochet.
Ne jamais couper de tiges de plus de 13 mm (1/2 po) de
diamètre.
Toujours utiliser la bandoulière et la régler pour pouvoir
travailler confortablement. Tenir fermement les deux
poignées pendant les travaux de coupe avec une lame.
Garder la lame loin du corps, au-dessous du niveau de la taille.
Ne jamais tailler avec la débroussailleuse avec la lame à plus
de 762 mm (30 po) du sol.
Conserver ces instructions. Les consulter fréquemment et les
utiliser pour instruire les autres utilisateurs éventuels. Si cet
outil est prêté, il doit être accompagné de ces instructions.
RÈGLES DE SÉCURITÉ GÉNÉRALES
Porter un équipement de protection et respecter toutes les
instructions de sécurité. Si l’outil est équipé d’un embrayage,
s’assurer que l’accessoire de coupe s’immobilise lorsque
le moteur tourne au ralenti. Lorsque le moteur est arrêté,
s’assurer que l’accessoire de coupe est immobilisé avant
de poser l’outil.
NOTE : CONSULTER LE MANUEL D’UTILISATION DE L’ACCESSOIRE EN QUESTION AFIN
DE PRENDRE CONNAISSANCE DES RÈGLES DE SÉCURITÉ SUPPLÉMENTAIRES.
