NAKAYAMA NS2635 Two-Stroke Back Sprayer Instruction Manual

Names of Components

Assembling

• Attach the wide nozzle, the nozzle pipe, the ball cock in that order to the spray hose, and connect the other end of the hose to the spray outlet.

• Mix 25ml of special oil for two stroke air-cooled engines for every 1L of petrol of 94 octane or more.
  Be sure to use 2 stroke special oil.

• Neither overfill nor spill the fuel on to the engine.
  Be sure that the engine has stopped and cooled down.

Dilution Of Chemicals / Charging To The Chemical Tank

Caution : Agricultural chemicals are extremely dangerous, and must be handle with care. Read the manual for specific chemical carefully before use.
Dissolve water dispersible power in a separate container before filling. Be sure not to get foreign material into the chemicals.

Open the air bleed nozzle, and bleed until the chemical is draining out, and then close the nozzle securely. Before spraying the agrochemical, be sure to put on suitable protective clothing to protect yourself against contact with and breathing it. Observe the following cautions for safe operation:

1. Be sure to close the chemical tank cover securely.
2. Check the spray hose and nozzle connections to make sure there are no leakage.
3. Always stop the engine before refilling the fuel tank or changing the nozzle.
4. When carrying a full chemical tank, be careful not to lose your balance.

Starting the engine

Important : When starting the engine, be sure to fill the chemical tank with pure water or chemical liquid. Never run the engine when the chemical tank is empty.

Pump the primer bulb until fuel can be seen flowing through the fuel return line, and pull the choke lever to full close. (During
hot weather and when the engine is already warmed up, the choke lever may be set to either half open or full open.)
Set the throttle lever to the middle speed position (not necessarily to maximum).

Pull the recoil starter lightly 2-3 times.
Pull the recoil starter strongly to start the engine.
If the engine stops after a few revolutions, set the choke to half open, and pull the recoil starter rope strongly again to restart
it.

Note: If the engine does not catch even after the starter is pulled several times, set the choke lever to full open and pull the
starter rope. Be sure not to pull the starter lever completely out. After the engine starts, open the choke lever slowly, move
the throttle lever to the low-speed side, and let the sprayer warm up for 2-3 minutes.

Important:

When the pressure control valve handle is changed to INSECTICIDE or HERBICIDE, with the throttle being fully open at HIGH PRESSURE position of pressure control valve handle, the engine speed will become too high, corresponding to the extent of lowered pressure. Therefore, use the equipment with the throttle lever some what turned back from the fully opened condition, when the equipment is used at the position for INSECTICIDE or HERBICIDE.

Be careful of the amount of fuel in the fuel tank, and refill it when it becomes low.

1. Turn the handle of the control valve, and set it to the position for HERBICIDE, INSECTICIDE or HIGH PRESSURE to match the pressure to operating conditions.
2. Check spraying conditions and the status of the equipment, then shoulder the equipment and set the throttle lever to the high speed position.
3. When the nozzle cock is opened, chemicals will be atomized as they come out of the nozzle.
   

Stopping the machine

Temporary halt during operation.

1. Close the nozzle, and return the throttle lever to low speed.
2. Press the engine stop button.
3. After the engine stops, set the sprayer down and close the fuel cock.

Stopping the sprayer after completing spraying.

1. Remove the chemical tank drain cap, and drain off all of the chemicals.
2. Fill the chemical tank with clear water, operate the engine, and clean the pump and hose interior by spraying the clean water. Drain off remaining water through the drain.
   
   Start the engine at just less than high speed for 15- 20 seconds to spray out the water in the spray hose and nozzle. When water stops coming from the nozzle, turn off the engine at once.

Maintenance

Cleaning the air cleaner

Plug

Storage

After using the sprayer for the season, store it until the next season of use as follows:

1. Drain off all fuel from the fuel tank and the carburettor.
2. Remove the spark plug and coat the interior of the cylinder with a small amount of oil. Pull the recoil starter lightly 2-3 times to spread the oil over the cylinder completely.
3. Pull the recoil starter out slightly and stop it in place where you fuel the pull starter (compression starts).
4. Clean the entire sprayer completely, cover it so it does not accumulate dirt and dust, and store it in a dry, coll location.
