PRECAUTIONS BEFORE SPRAYING
• Make sure you have the correct protective
clothing, headgear, rubber gloves and
boots, a protective mask, goggles, a towel,
protective cream, etc., to prevent chemicals
from coming into contact with your skin or
entering your lungs. When spraying, wear
this protective gear to prevent any risk of
injury.
• Store chemicals in a locked storage box,
locker, or other safe place out of the reach of
children.
• Carefully read the instructions for using the
chemicals, and familiarize yourself with the
level of toxicity, method of use, etc.
• 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 chemical spraying area.
• Before spraying, 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, 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, use a rope or
similar to x the sprayer rmly to the cargo
trailer in an upright position. Do not transport
by bicycle or motorbike, as this is dangerous.
PRECAUTIONS CONCERNING FUEL

Safety Precautions
PRECAUTION WHEN STARTING THE
ENGINE
• Keep children, animals, etc. well away when
starting the engine and spraying.
• Check if the adjust lever (outlet valve open/close
lever) is in full close position. Otherwise, large
volumes of chemicals will spout immediately
when the engine starts and are dangerous.
• Assure that there is no person in front of the
spray head (output nozzle) when starting the
engine. Remaining chemicals stuck in the spray
pipe may spout out.
PRECAUTIONS WHEN SPRAYING
• Since protective clothing generally offers
poor ventilation and thus places stress
on the body, there is a risk of contracting
heatstroke or other illness when operating for
long periods under high temperatures. 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, 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 hold the grip rmly at all times
and be careful not to point the nozzle in the
direction of people or animals.
• While spraying be careful of the wind
direction and always stand on the upwind
side, to avoid spraying yourself with
chemicals.
• Should you begin to feel even slightly unwell
while spraying, consult a doctor immediately.
When doing so, inform the doctor of the
name of the chemical you were using, the
conditions of use, etc.
• If the sprayer is tilted the chemical may leak
out through the air holes in the cap. When
spraying always make sure you have a rm
footing and maintain your balance.
• Do not touch the spark plugs or plug cords
while the engine is running, as you may get
an electric shock.
• Do not touch the mufer, spark plugs, or
other metal parts with your bare hands while
the engine is running or immediately after
stopping the engine, as there is the risk of
burns due to high temperatures.
PRECAUTIONS AFTER SPRAYING
• 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, 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
underwear, and wash them thoroughly.
Clothes worn during spraying should not be
worn again the following day.
• After spraying, limit your alcohol intake and
rest thoroughly by going to bed early. If you
feel even slightly unwell, see a doctor as
soon as possible.
OTHER PRECAUTIONS
• When engaged in spraying work over a
protracted period of time, have your health
checked regularly.
• Carry out spraying in a planned fashion,
keeping a daily record of the date and time of
spraying, the chemicals used, the target pest,
contents of the work, duration of the work,
and other details.
• Keep the following points in mind when
selecting or using protective gear.
a) Protective clothing
Choose clothing that is cool to wear and
offers good ventilation and waterproong. In
addition, wear items that enable you to carry
out spraying work in total comfort and safety.
b) Spraying hood

Fuel
■ 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 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
• Exhaust emission are controlled by the
funda mental engine parameters and
components (eq., carburation, ignition timing
and port timing) without addition of any
major hardware or the introduction 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 prescribed, 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 necessary 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 sufficiently agitate the
mixed gasoline in the container.
4. Do not smoke or place hot objects near fuel.
■ 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. In the case of scrapping the used mixed
oil container, scrap it only at an authorized
repository site.

2. Use neutral detergent and warm water to clean
the lter element. After cleaning, air dry the
element completely and moisten with a small
amount of 2 cycle motor oil.
■ FUEL FILTER
• A clogged fuel lter may cause poor acceleration
of the engine. Check periodically to see if the
lter is clogged with dirt. The lter can be taken
out of the fueling port using a small wire hook.
Disconnect the lter assembly from the fuel pipe
and unhook the retainer to disassemble it. Clean
the components with gasoline.
■ Spark plug
• After every 50 hours of operation, detach the
spark plug and remove dirt from the electrodes
with a wire brush or similar.
• The correct electrode gap is 0.6 to 0.7mm.
• When replacing plugs, use designated items.
IMPORTANT
• If too much fuel is absorbed or poor quality oil
is used, the spark plug electrodes become dirty,
making the engine harder to start.
• Note that using any spark plug other than those
designated may result in the engine failing to
operate properly or in the engine becoming
overheated and damaged.
• To install the spark plug, rst turn the plug until it
is nger tight, then tighten it a quarter turn more
with a socket wrench.
■ MUFFLER
WARNING
• Inspect periodically, the muffler for loose
fasteners, any damage or corrosion. If any
sign of exhaust leakage is found, stop
using the machine and have it repaired
immediately.
IMPORTANT
• Before starting operation, always make sure
to check if the mufer is properly held by three
bolts to the cylinder. (Fastening Torque : 8~12
N·m)

1. Remove the mufer, insert a screwdriver into the
vent, and wipe away any carbon buildup. Wipe
away any carbon buildup on the mufer exhaust
vent and cylinder exhaust port at the same time.
2. Tighten all screws, bolts, and ttings.
3. Check to see if any oil or grease has worked its
way in between the clutch lining and drum, and
if it has, wipe it away using oil-free, lead-free
gasoline.
■ AIR INLET NET
IMPORTANT
• Blowing air is taken in from the air inlet net.
When air ow has dropped down during
operation, stop the engine and inspect the air
inlet net for blocking by obstacles.
• Note that failure to remove any such obstacles
may result in the engine becoming overheated
and damaged.
WARNING
Never use the blower without the net of the
machine. Before each use, check that the
net is attached in place and is free from any
damage.
■ SHOULDER STRAP
• If the shoulder strap is damaged it may break
during use, thus causing the product to fall
and resulting in personal injury. Follow the
instructions below to replace the shoulder strap
with new one.
1. Pass the upper end of the strap through the
hanger, making the FLAPPED SIDE OUTSIDE.
2. Put the end of the strap through the ring on the
strap, and then push the ring toward the hanger
as close as possible.
Maintenance
(1)Ring
(2)Flapped side
WARNING
The flap on the end of the strap works as
a stopper. Never install the strap with the
flapped side inside, or the unit may fall from
the operation, which could result in injury to
the operator and/or damage to the unit.
■ SPRAY DEVICE
IMPORTANT
• As fertilizers are easy to absorb moisture, left
behind fertilizers will cause error for the
shutter operation. After spraying fertilizers,
clean the spray device carefully.
• Correct length of the chemical tank locking
hooks is 45-46mm. Shorter hooks than this
cause excess fixing forces and may end up
with deformation or breakage of related
components. Longer hooks cause insufficient
contact of the tank and chemicals may leak.
• For long time storage of the sprayer, leave the
chemical tank cap loose. Otherwise, a cap
gasket may be deformed.

WARNING
• When draining fuel, be careful not to spill it. If
fuel is spilt, wipe off thoroughly. In addition,
be sure to close the storage container cap
tightly.
IMPORTANT
• If fuel is left in the engine for protracted periods,
the inside of the carburetor may become
clogged and cause engine malfunction (faulty
starting and insufcient output).
• During storage, slightly loosen the cap of the
chemical uid tank. If screwed too tightly, the
gasket may become distorted.
On completion of all work procedures, when not
planning to use again for a protracted period carry
out the following pre-storage care, to prevent
trouble caused by time-lapse changes.
Storage
Disposal
When disposing your machine, fuel or oil for the
machine, be sure to allow your local regulations.
1. Clean the chemical uid tank and nozzle (see
page 11).
2. Remove dirt from the sprayer, inspect it for any
damage or looseness, and, if any abnormality is
found, correct it thoroughly in preparation for the
next time you use the unit.
3. Drain the fuel tank.
4. Start the engine, and leave it in idling condition
until all the fuel inside the carburetor is spent
and the engine comes to a natural stop.
5. Remove the spark plug and put a few drops (1
to 2 cc) of 2-cycle oil inside the engine. After
pulling the starter rope 2 or 3 times, return the
spark plugs to their original position and stop in
compressed position.
6. After oiling the throttle lever and other metal
parts with anti-corrosive oil, cover the sprayer
and store indoors in a low-humidity location.
