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.

Cautions when using this product
Fuel
Fuel is inflammable, therefore observe the following to prevent fire.
・Don't bring a naked flame close to where fuel is supplied or the machine is main-
tained.
・When supplying fuel, make sure you stop the engine and wait for the engine to cool
down. If fuel is spilled, wipe it off.
・When starting the engine, be more than five meters from the supply tank.
・Make sure you observe the correct mixing ratio of two-cycle engine oil to prevent
the pollu-tion of the environment and prevent machine trouble.
・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.
Recoil Starter・Potential danger on recoil disassembly.Do not disassemble the recoil.Contact the
sales office for repair.
・Do not pull the starting rope thoroughly.Potential failure may be concerned if
disregarded.

・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.

pressure control valve handle, engine
revolutions increase as pressure decreases.
When using this machine at the "INSECTICIDE",
"HERBICIDE" position, use at a posi-tion little bit
back from full open throttle.

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.

Cleaning of air cleaner
・When elements become dirty or clogged,
reduced performance or difficulty starting is
observed. Clean the elements regularly to
remove dirt and prevent clogging.
・When cleaning the element, wash it using gaso-
line, dip it in the blended fuel used and install it
after squeezing it hard to remove excess fuel.
Pump
Check for worn piston packing and seal packing,
