Frequently Asked Questions - MS068 Maruyama

What type of fuel does the Maruyama MS068 sprayer use?

The MS068 uses a mixed gasoline at a ratio of 25:1 (gasoline to 2-cycle oil). Always use 2-cycle exclusive oil.

How do I start the engine on the MS068?

To start, pump the primer bulb until fuel flows through the return line. Set the choke lever to full close (or open if warm). Set throttle lever to middle speed. Pull the recoil starter lightly 2-3 times, then pull strongly to start. After starting, open choke slowly and warm up for 2-3 minutes.

What is the maximum spray pressure of the MS068?

The maximum pressure is 360 PSI (2.5 kgf/cm²). Adjust pressure using the pressure control valve handle to match operating conditions (HERBICIDE, INSECTICIDE, or HIGH PRESSURE).

How do I clean the air cleaner?

Remove the air filter cap and clean the element. Squeeze firmly to remove dirt. If necessary, replace the element. Regular cleaning ensures proper engine performance.

What is the warranty period for the MS068?

The warranty is 3 years for residential (non-institutional, non-income producing) use and 1 year for industrial, commercial, or rental use. Engine components have separate warranty as per engine manufacturer.

How should I store the sprayer for the off-season?

Drain all fuel from tank and carburetor. Remove spark plug, add a few drops of oil into cylinder, and pull recoil starter to distribute oil. Stop when compression starts. Clean thoroughly and store in a dry, cool place.

Why is there no suction from the pump?

Possible causes: loose hose connections (tighten), clogged suction hose (clean), worn piston packing (replace), or foreign objects in valve parts (disassemble and clean).

How do I adjust the pressure setting?

Turn the pressure control valve handle to the desired position: HERBICIDE (low pressure), INSECTICIDE (medium pressure), or HIGH PRESSURE (maximum). Ensure throttle lever is adjusted accordingly to avoid excessive engine speed.

What spark plug is required for the MS068?

The recommended spark plug is NGK BPM6Y. Ensure proper gap (not specified in manual, but standard for this plug) and check insulation for faults.

How do I stop the engine during operation?

To stop temporarily, close the nozzle and return throttle lever to low speed, then press the engine stop button. After stopping, set the sprayer down safely.

Accessories

Assembling

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

Pre-operation preparation

Oiling

Be sure to use 2 cycle exclusive oil.

Be sure of the engine stopped and cool.

Neither overfill nor spill the fuel on to the engine.

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 powder in a separate container before filling. Be sure not to get foreign material into the chemicals.

Always fill the chemical tank through the strainer so that contaminants are not mixed into the chemicals.

Open the 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:

a) Be sure to close the chemical tank cover securely.
b) Check the spray hose and nozzle connections to make sure there are no leaks.
c) Always stop the engine before refilling the fuel tank or changing the nozzle.
d) 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 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 open, and pull the recoil starter rope strongly again to restart it. Note: If the engine dose 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.

Pull briskly

Operation

graph TD
    A["When the engine starts and pump is suctioning"] --> B["STARTING"]
    C["When low pressure spraying is necessary"] --> B
    D["When high pressure is required"] --> E["HIGH PRESSURE"]
    F["Normal spraying"] --> G["INSECTICIDE"]
    H["Pressure control valve handle"] --> I["Normal spraying"]

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.

[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. There for, 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.

Stop

Temporary halt during operation

a) Close the nozzle, and return the throttle lever to low speed.
b) Press the engine stop button.
c) After the engine stops, set the sprayer down.

Stopping the sprayer after completing spraying

a) Remove the chemical tank drain cap, and drain off all of the chemical.
b) Fill the chemical tank with clean 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

Remove the air filter cap to clean the element

Squeeze firmly

Plug

Pull 2 - 3 times

Storage

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

a) Drain off all fuel from the fuel tank and the carburetor.
b) 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.

1. Remove the plug.
   

2. Pull 2 or 3 times.

3. Apply a few drops of oil.
   

1. Connect the plug.

c) Pull the recoil starter out slightly and stop it in place where you feel resistance start (compression starts).
d) Clean the entire sprayer completely, cover it so it dose not accumulate dirt and dust, and store it in a dry, cool location.
