• Carefully read the instructions for using the chemicals,
and familiarize yourself with the level of toxicity, method
of use, etc.
• Please pay all due consideration to the area in which
you will be spraying, to ensure that you do not pollute
the water supply, rivers, lakes, ponds, etc., or cause
any damage to residents, passers-by, livestock, etc.
• Prepare yourself physically on the day before spraying,
by for example cutting down on alcoholic beverages
or late-night work.
Donotallowchildren,animals,etc.,toenterthechemi-
calsprayingarea.
• Before spraying, please prepare fully by inspecting
sprayer nozzles and checking for abnormalities such
as loose screws or spray hose connections, fuel leaks,
defective or broken uid gaskets, or damage to the
carrying band.
PRECAUTIONS WHEN TRANSPORTING CHEMICALS
• When transporting chemicals, please handle with care
to ensure that there is no spillage of chemicals from
torn bags, broken bottles, or loose stoppers.
• Do not carry chemicals in the same container as food.
PRECAUTIONS WHEN TRANSPORTING THE
SPRAYER
• Do not transport the sprayer while it has chemicals or
fuel in the tank, as these could leak out as a result of
impact during transportation.
• When transporting in a vehicle, please use a rope or
similar to x the sprayer rmly to the cargo trailer in
an upright position. Please do not transport by bicycle
or motorbike, as this is dangerous.
PRECAUTIONS CONCERNING FUEL
• The engine of this product is fueled by “mixed gasoline”
that includes highly combustible fuel. Do not refuel or
store fuel containers where there is any risk of com-
bustion from incinerators, burners, bonres, kitchen
stoves, electric sparks, welding sparks, etc.
• Smoking while spraying or refueling is dangerous.
Please avoid this at all costs.
• When refueling during use, always stop the engine and
make sure there are no naked ames in the vicinity
before relling.
• Any fuel spilt during refueling should be wiped off com-
pletely with a rag or similar before starting the engine.
• After refueling, seal the fuel container, tightly close the
fuel tank cap, and start the engine at least 3 meters
away.
PRECAUTIONS WHEN REFILLING CHEMICALS
• Before lling the tank with chemicals, please make sure
that the spray lever is completely at rest.

not fully tightened the cap may become loose during
spraying, with the risk of physical exposure to the
chemicals.
PRECAUTION WHEN STARTING THE ENGINE
• Please keep children, animals, etc. well away when
starting the engine and spraying.
PRECAUTIONS WHEN SPRAYING
• Since protective clothing generally offers poor ventila-
tion and thus places stress on the body, there is a risk
of contracting heatstroke or other illness when operat-
ing for long periods under high temperatures. Please
avoid spraying on hot days, aiming instead for early
morning and late afternoon times when temperatures
are relatively cool and winds are low.
• When starting work, please pay all due consideration
to the spraying time, wind direction, etc., to ensure that
no noise disturbance or chemical hazard is caused to
nearby residents, passers-by, farm crops, and so on.
• While spraying please hold the grip rmly at all times
and be careful not to point the nozzle in the direction
of people or animals.

PRECAUTIONS AFTER SPRAYING
• Please seal unused chemicals and store them out of
the reach of children.
• Do not simply discard empty chemical containers,
but dispose of them safely by incinerating, burying, or
another similar method. In addition, please take every
care that the water used to clean spraying tools does
not create any hazard.
• Fully inspect and maintain protective clothing, masks,
gloves, and other protective gear in preparation for
the next session.
• After completing the work and tidying away chemicals
and spraying tools, you should immediately take a bath
or wash your hands, feet, face, etc. thoroughly with
soap, as well as washing your mouth out.
• You should change all clothes worn, including under-
wear, and wash them thoroughly. Clothes worn during
spraying should not be worn again the following day.
• After spraying, please limit your alcohol intake and
rest thoroughly by going to bed early. If you feel even
slightly unwell, please see a doctor as soon as pos-
sible.
OTHER PRECAUTIONS
• When engaged in spraying work over a protracted pe-
riod of time, please have your health checked regularly.
• Please carry out spraying in a planned fashion, keep-
ing a daily record of the date and time of spraying, the

FUEL
WARNING
• Gasoline is very flammable. Avoid smo king or
bringing any flame or sparks near fuel. Make sure
to stop the engine and allow it cool before refueling
the unit. Select outdoor bare ground for fueling
and move at least 3 m (10 ft) away from the fueling
point before starting the engine.
• The Husqvarna engines are lubricated by oil specially
formulated for air-cooled 2-cycle gasoline engine use.
If Husqvarna oil is not available, use an anti-oxidant
added quality oil expressly labeled for air-cooled
2-cycle engine use (JASO FC GRADE OIL or ISO
EGC GRADE).
• Do not use BIA or TCW (2-stroke water-cooling type)
mixed oil.
•
• RECOMMENDED MIXING RATIO
GASOLINE 50 : OIL 1 (when using Husqvarna
genuine oil)
• Exhaust emission are controlled by the funda-
mental engine parameters and components (eq.,
carburation, ignition timing and port timing) with-
out addition of any major hardware or the introduc-
tion of an inert material during com bustion.
• These engines are certied to operate on unleaded
gasoline.
• Make sure to use gasoline with a minimum octane
number of 89RON (USA/Canada: 87AL).
• If you use a gasoline of a lower octane value than pre-
scribed, there is a danger that the engine temperature
may rise and an engine problem such as piston seizing
may consequently occur.
• Unleaded gasoline is recommended to reduce the
contamination of the air for the sake of your health
and the environment.
• Poor quality gasolines or oils may damage sealing
rings, fuel lines or fuel tank of the engine.
HOW TO MIX FUEL
WARNING
• Pay attention to agitation.
1. Measure out the quantities of gasoline and oil to be
mixed.
2. Put some of the gasoline into a clean, approved fuel
container.
3. Pour in all of the oil and agitate well.
4. Pour in the rest of gasoline and agitate again for at least
one minute. As some oils may be difcult to agitate
depending on oil ingredients, sufcient agitation is nec-
essary for the engine to last long. Be careful that, if the
agitation is insufcient, there is an increased danger
of early piston seizing due to abnormally lean mixture.
5. Put a clear indication on the outside of the container to
avoid mixing up with gasoline or other containers.
6. Indicate the contents on outside of container for easy
identication.
FUELING THE UNIT
1. Untwist and remove the fuel cap. Rest the cap on a
dustless place.
2. Put fuel into the fuel tank to 80% of the full capacity.
3. Fasten the fuel cap securely and wipe up any fuel
spillage around the unit.
WARNING
1. Select bare ground for fueling.
2. Move at least 3 meters (10 feet ) away from the fueling
point before starting the engine.
3. Stop the engine before refueling the unit. At that time,
be sure to sufciently agitate the mixed gasoline in
the container.
FOR YOUR ENGINE LIFE, AVOID:
1. FUEL WITH NO OIL (RAW GASOLINE) It will cause
severe damage to the internal engine parts very
quickly.
2. GASOHOL - It can cause deterioration of rubber and/
or plastic parts and disruption of engine lubrication.
3. OIL FOR 4-CYCLE ENGINE USE It can cause spark
plug fouling, exhaust port blocking, or piston ring
sticking.
4. Mixed fuels which have been left unused for a period of
one month or more may clog the carbu retor and result
in the engine failing to operate properly.
5. In the case of storing the product for a long period of
time, clean the fuel tank after rendering it empty. Next,
activate the engine and empty the carburetor of the
composite fuel.
6. 6. In the case of scrapping the used mixed oil
container, scrap it only at an authorized repository site.
NOTE
• As for details of quality assurance, read the description
in the section Limited Warranty carefully. Moreover,
normal wear and change in product with no functional
inuence are not covered by the warranty. Also, be
careful that, if the usage in the instruction manual is
not observed as to the mixed gasoline, etc. described
therein, it may not be covered by the warranty.

■ Starting engine
WARNING
• Before starting the engine, make sure that the spray
lever (spray valve) is completely returned. Starting
with the spray lever still pulled out is dangerous, as
chemical uid may spray out of the nozzle as soon as
the engine is started.
• To start the engine, place the sprayer on an even and
stable surface or platform. If the sprayer is unstable,
the reaction on starting etc. may cause it to fall.
IMPORTANT
• Do not allow the chemical uid or water in the tank to
run out while the engine is running. If the engine runs
empty it may cause breakage of the spray pump.
• Make sure that the gear oil is lled until the middle of

(1) bolt
(2) window
(3) drain bolt
(1) grease cup
INTAKE AIR COOLING VENT
WARNING
• Never touch the cylinder, muffler, or spark plugs
with your bare hands immediately after stopping
the engine. The engine can become very hot when
in operation, and doing so could result in severe
burns.
• When checking the machine to make sure that
it is okay before using it, check the area around
the muffler and remove any wood chips or leaves
which have attached themselves to the brushcut-
ter. Failing to do so could cause the muffler to
become overheated and that in turn could cause
the engine to catch on fire. Always make sure that
the muffler is clean and free of wood chips, leaves,
and other waste before use.
• Check the intake air cooling vent and the area
around the cylinder cooling fins after every 25
hours of use for blockage. Note that it is neces-
sary to remove the upper cover and the lower
cover in order to be able to view the upper part of
the cylinder.
IMPORTANT
• If waste gets stuck and causes blockage around the
intake air cooling vent or between the cylinder ns, it
may cause the engine to overheat, and that in turn may
cause mechanical failure on the part of the brushcutter.

caja de almacenamiento, armario u otro lugar seguro,
fuera del alcance de los ninos.
• Lea detenidamente las instrucciones de uso de las
sustancias químicas, y familiarícese con el nivel de
toxicidad, método de uso, etc.
• Analice cuidadosamente el rea que va a rociar, asegur
ndose de no contaminar el suministro de agua, ríos,
lagos, lagunas, etc., ni de causar danos a los resi-
dentes, personas que pasan, ganado, etc.
• Prep rese físicamente el día anterior a la operación de
pulverización disminuyendo, por ejemplo, el consumo
de bebidas alcohólicas o el trabajo nocturno.
• No permita el ingreso de ninos, animales, etc., al rea
de pulverización de sustancias químicas.
• Antes de comenzar a rociar, inspeccione completa-
mente las toberas de pulverización y compruebe si
hay algúntipo de anormalidad como, por ejemplo,
tornillos sueltos o una conexión poco segura de la
manguera de pulverización, fugas de combustible,
empaquetaduras de líquidos defectuosas o rotas, o
danos en la cinta de transporte.
PRECAUCIONES AL TRANSPORTAR SUSTAN-
CIAS QUIMICAS
• Al transportar sustancias químicas, h galo con precau-
ción teniendo cuidado de no derramar las sustancias
debido a bolsas rotas, botellas quebradas o retenes
sueltos.
• No transporte las sustancias químicas en el mismo
recipiente que la comida.

PRECAUCION AL ARRANCAR EL MOTOR
• Mantenga a ninos, animales, etc. bien alejados al
arrancar el motor y durante la operación de pulver-
ización.
PRECAUCIONES DURANTE LA OPERACION DE
PULVERIZACION
• Debido a que la ropa protectora en general ofrece mala
ventilación y por consiguiente ejerce una fuerte carga
sobre el cuerpo, existe el riesgo de sufrir insolación u
otra afección al usar el pulverizador por períodos pro-
longados bajo altas temperaturas. Evite rociar en días
calurosos; programe, en cambio, la pulverización para
temprano en la manana o para las últimas horas de la
tarde cuando las temperaturas son m s moderadas y
los vientos escasos.
• Al iniciar un trabajo, considere debidamente factores
tales como hora de pulverización, dirección del viento,
etc., para evitar molestias por ruido o situaciones con
riesgo de contaminación por sustancias químicas a los
vecinos, personas que pasan, cosechas, etc.
• Mientras rocía, sujete rmemente el mango en todo
momento y tenga cuidado de no apuntar la tobera
hacia personas o animales.
• Mientras rocía, considere la dirección del viento; p
rese siempre a favor del viento para evitar rociarse a
s mismo con las sustancias químicas.
• Si comienza a sentir aunque sólo sea un ligero mal-
estar mientras rocía, consulte inmediatamente a un
médico. Al hacerlo, infórmele al médico el nombre de
la sustancia química que estaba usando, describa las
condiciones de uso, etc.
• Si el pulverizador es inclinado, la sustancia química
podr salirse por los oricios de ventilación de la tapa.
Al rociar, asegúrese siempre de estar bien parado y
de mantener el equilibrio.
• No toque las bujías o los cables de las mismas mien-
tras el motor est en marcha; de lo contrario, usted
podría sufrir una descarga eléctrica.
• No toque el silenciador, bujías u otras piezas met
licas con las manos descubiertas mientras el motor
est en marcha o inmediatamente después de pararlo,
5. Para un funcionamiento seguro
ya que podría sufrir quemaduras debido a las altas
temperaturas.
PRECAUCIONES POSTERIORES A LA PULVER-
IZACION
• Selle las sustancias químicas sin uso y gu rdelas fuera
del alcance de los ninos.
• No simplemente deseche los envases de sustancias
químicas vacíos, sino que h galo en forma segura,
ya sea quem ndolos, enterr ndolos o por medio de
otro método similar. Asimismo, tome todas las pre-
cauciones para que el agua usada para lavar las her-
ramientas de pulverización no constituya un peligro.
• Inspeccione completamente y efectúe el mantenimien-
to de rigor de la ropa protectora, m scaras, guantes y
otros elementos de protección a modo de preparación
para la próxima sesión.
• Después de nalizar el trabajo y guardar las sustan-
cias químicas y herramientas de pulverización, tome
