- Store chemicals in a safe place, and be careful not to break open their containers during transportation.

- 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 spraying method to protect workers and houses. When spraying chemicals, work from upwind to downwind. Also give consideration to prevent chemicals from drifting or scattering on crops, enclosures, fish-breeding ponds, and houses nearby.

- When working in a greenhouse, pay attention to ventilation.

- Spray all of the chemicals and leave none in the tank.

CAUTION

• Do not use this machine when there are people, children, oranimals, 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.

Assembly of nozzle

Wide nozzle Nozzle pipe Lever cock Spraying hose assembly

After confirming the existence of packing, securely tighten nozzle pipe to lever cock, and wide nozzle to nozzle pipe. Tighten the screw securely after confirming the packing to make sure there is no water leakage. Over-tightening will cause extrusion or break the packing. Correct tightening pressure is important.

Discharge opening

Connect opposite side of hose to discharge opening of the spraying machine.

Oil feeding and mixing

Oil feeding

• Make sure you use Fuel and oil mixture

Gasoline : exclusive oil

50 : 1

Use exclusive oil for two-cycle air cooled 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 filling 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 fill fuel above the standard line. There is the possibility of leakage.
• When a fuel leakage is found, use the engine after repairs are done.
  • After filling fuel, make sure you close the fuel tank cap.

CAUTION

• If operating the machine with gasoline alone, the engine will seize.
  Make sure to mix exclusive two-cycle engine oil in the specified 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.

Cover of chemical tank Close securely

• After confirming packing for chemical cover, close the cover securely. Otherwise, chemicals will spill and you might be covered with them when you carry the machine on your back.

5 Engine will start.

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. Don't release starting rope from pulled state, and let it return to its original state gradually.

CAUTION

If the engine does not start by repeated action, try pulling the rope after fully opening the choke.

※ If the engine still does not start, refer to page 25.

Starter rope Recoil Starter

6 Return choke slowly.

Open

CAUTION

• 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 after making the choke fully open.
  • 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 possibility of poor acceleration and engine stalling.
  • Supply fuel prior to use if possible. This will make starting next time easy.

Operation and shutting down

Operation

1 Turn the handle of the pressure control valve until there is sufficient pressure for work such as spraying weeds (fixed position).
