Chemicals
・Read labels of chemicals to be used carefully,
and understand the method of use and cau-
tions. When spraying quantity per tank
(1000m2) or if the chemical is mistaken, agri-
cultural chemicals can cause damage.
・Store chemicals in a safe place, and be careful
not to break open their containers during trans-
portation.
・Treat chemical containers to ensure safety.
・Pay attention to the handling of chemicals. If a
chemical enters into eye or mouth, wash it off
with water immediately.
・If you feel ill, see a doctor immediately.
・According to wind direction, change the spray-
ing method to protect workers and houses.
When spraying chemicals, work from upwind
to downwind. Also give consideration to pre-
vent chemicals from drifting or scattering on
crops, enclosures, fish-breeding ponds, and
houses nearby.
・When working in and greenhouse, pay
attention to ventilation.
・When preparing chemicals, prepare the
necessary amount only in accordance with the
established spraying plan. If too much
chemicals are left over, acton is difficult.
・Do not use this machine when there are people, especially children, near the site.
・Because the tank when completely filled with the chemical is very heavy, pay
careful attention not to hurt your lower back when carrying it.
・Always adopt a safe working posture when carrying the tank. Do not work at
elevated sites using stairs or ladders while carrying the tank.

・Don't use gasoline alone as fuel.
Engine
・Temperature of engine is high during operation and immediately after stopping. You
will get a burn if you touch the muffler, cylinder fin, etc.
・When starting the engine, confirm that the ball valve is securely closed to prevent
explosion caused by a sudden spray.
・Don't touch the spark plug during engine operation. You might get shock.
・Don't operate inside a room. You might suffer by carbon monoxide poisoning.
・Don't breathe in the exhaust gas from the engine.

Oil feeding and mixing
Oil feeding
・Make sure you use blended fuel.
Gasoline : exclusive oil
25 : 1
Use exclusive oil for two-cycle engine engines.
Neither overfill nor
spill the fuel on to
the engine.
DANGER
There is a possibility of fuel igniting. Make sure
you observe the following items.
・When feeding fuel, stop the engine and
ensure no source of fire such as cigarette is
close to the area.
・Don't spill fuel. If fuel is spilled, wipe it all off
at once and start the engine after it is dry.
・Don't feed fuel above the standard line.
There is the possibility of leakage.
・When a fuel leakage is found, use the
engine after repair are done.
・After feeding fuel, make sure you close the
fuel tank cap.
・If operating the machine with gasoline
alone, the engine will seize.
Make sure to mix exclusive two-cycle engine
oil in the specifled quantity.
・The mixing ratio shall be the designated
ratio for exclusive two-cycle engine oil.
・Use lead-free gasoline for automobiles for
fuel.
Mixing chemicals
・Read the instructions for the chemical to be
used carefully and follow the mixing method
and cautions for use.
CAUTION
・After confirming the proper placement of the
chemical cover, close the cover securely.
Otherwise, chemicals will spill and you might
be covered with them when you carry the

CAUTION
・When starting the engine, make sure to put
water or chemicals into the chemical tank.
Without water or chemicals in the tank, the
pump will break down. Never run the pump dry.
・It is confirmed that the ball cock has closed
before it starts.
Perform priming.Push priming pump installed
in front of the carburetor several times slowly,
and confirm that fuel fills the priming pump
and returns to the tank through the clear
return line.

Fully close the choke. (In hot weather or
when engine is hot, the choke should be

After pulling starting rope gently by two or
three times, pull it hard to start the engine.
[Pulling method for starting rope]
1. Grasp starting rope tight with right hand.
2. Hold chemical tank with left hand.
3. Pull starting rope slowly until resistance is felt.
4. Pull starting rope straight from entrance of
starter.
5. Do not pull starting rope to the end.
6. Do not release the starter rope handle when
rope is extended. Allow the recoil to rewind the
rope gradually.
5
If the engine does not start by repeated action,
try pulling the rope after fully opening the choke.
CAUTION
※If the engine still does not start, refer to
page 17. ・Frequent operation of choke when starting the
engine causes too much fuel to be sucked in,
making the engine difficult to start. In that
case, start with the choke in the fully open
position.
・After starting the engine, accelerate bit by bit
quickly by opening and closing the throttle
lever several times.
・This operation is to bleed air in the carburetor.
When there is air present, there is the possi-
bility of poor acceleration and engine stalling.
・Always prime the cabretor before use. This
will make starting next time easy.
CAUTION
Return choke slowly.
