Pre-Installation

Application

This is a clean water pump and cannot pump sewage or sea water. Avoid silt, oil stains, or other polluting liquids that can cause corrosion.

Performance

Specifications

Tools Required

Flathead screwdriver, Phillips screwdriver.

Package Contents

The package includes:

• A: Pump (1)
• B: Joint assembly (2 sets)
• C: Clamp (3)
• D: Strainer (1)

Installation

1. Place the unit as close to the water source as possible to minimize suction lift, obtain the best pumping performance, and aid in priming. A typical portable installation is shown in Figure 1.
   Figure 1 - Typical installation diagram shows the pump with discharge head, suction head, and total head labeled.
2. For permanent installation, mount the unit on a foundation that supports the weight of the pump and engine and provides stability. Bolting the unit directly to the foundation is advisable for most permanent installations.
   NOTE: Settling or shifting during operation can cause piping to place excessive strain on the pump and may damage the pump case. Set the pump on a hard, level surface.
3. Connect the suction hose (not included) to the pump suction. The hose must be rated to hold suction pressure and prevent collapse while the pump is running.
4. Ensure the suction hose rises continuously from the water source to the pump. High spots can trap air and make priming difficult. Make sure all connections are tight and free of air leaks.
   NOTE: The suction hose must be at least as large as the pump suction port for proper operation.
5. Install the strainer (provided with the pump) on the other end of the suction hose and secure it with a hose clamp. The strainer helps prevent the pump from becoming clogged or damaged by debris.
   WARNING: Never operate the pump without the strainer installed.

Installation (continued)

6. Connect the discharge hose (not included) to the pump discharge port. Use a short, large-diameter hose to reduce fluid friction and improve pump performance. A long or small-diameter hose will increase fluid friction and reduce pump output.
7. Tighten the clamp securely to prevent the discharge hose from disconnecting under high pressure.

Installation Requirements

• Use reinforced hose for the suction connection.
• The hose must be strong enough not to collapse during operation.
• Suction screen area must be at least four times the suction pipe area.
• All suction hose must slope upward toward the suction port.
• Support the hose and fittings to reduce strain on the pump case.
• The depth of the suction port must be at least four (4) times the diameter of the suction hose to avoid forming vortexes (e.g., 2" pipe x 4 = 8" minimum depth).

Operation

NOTE: Do not start or run the pump dry, as this can damage the mechanical seal.

NOTE: Add engine oil before startup.

1. A self-priming pump requires manual priming only at the first start-up. Under normal conditions, it will reprime automatically. If the pump is used in portable applications and the water has been drained from the pump case, re-prime before starting.
2. To prime, remove the water filler plug (labeled '6' in diagrams) from the top discharge port and fill the pump chamber with water. Replace the plug and start the pump. The pump will take a few minutes to evacuate air from the suction line. After several minutes of operation, it will be fully primed and pumping water. Priming time varies with suction line length and diameter.
3. Refer to the "Before Starting the Engine" and "Engine Operation" sections for starting and operating instructions.

Checking and Filling the Oil

The engine is shipped without oil and must be filled before starting.

1. Add oil by removing the fill cap and dipstick. Wipe off any excess oil from the dipstick.
2. Add oil until the level reaches the bottom of the opening.
3. Check the oil level by inserting the cleaned dipstick into the oil fill opening (do not screw it in). Remove and inspect the dipstick. Add oil if needed.
4. Reinstall the cap and dipstick.

Oil capacity is 0.63 quarts (0.6 liters). Use 10W-30 oil under normal conditions. Use 10W-40 oil for temperatures over 90°F (32°C). The engine has a low-oil monitoring system that will automatically shut off the engine if the oil level drops too low.

Adding Gasoline

Remove the fuel cap and fill the fuel tank with clean, fresh, unleaded gasoline with an octane rating of 86 or higher. Do not overfill. Clean up any spilled gasoline before starting.

Diagram shows fuel tank filling with a "Highest level" indicator.

Opening the Fuel Valve

Move the fuel valve lever to the right to allow fuel to the engine.

Diagram shows fuel valve lever and choke lever.

Closing the Choke

For a cold engine start, move the choke lever to the left (closed). As the engine warms up, move it towards the right (open). A warm engine should start with the choke open.

Engine Operation

Fill Water

Before starting the engine, remove the filler plug from the pump chamber and fill the chamber completely with water. Reinstall and tighten the plug securely.

Stopping the Engine

• Stop the engine by turning the ignition switch (1) to OFF.
• Move the fuel valve lever (2) to OFF (left).

Repair and Maintenance

Adjust and maintain the gasoline engine strictly according to the methods and instructions in this manual.

Daily Maintenance

Regular inspection and adjustment ensure excellent engine performance and a prolonged service life. Refer to the table below for the maintenance cycle.

Notes:

• '■' indicates maintenance interval of specified items.
• 'a' indicates maintenance to be carried out after first operation.
• For commercial engines and long-term operation, determine maintenance intervals appropriately.
• a. Increase maintenance interval if used in dusty areas.
• b. Maintenance items marked 'b' should be performed by authorized service stations unless users have appropriate tools and ability.

Replacement of Lubricating Oil

Run the pump with water for five (5) minutes, then shut it down before replacing the engine's lubricating oil for quick and complete release.

• Check if the oil tank cover is tightened.
• Unscrew the engine oil plug and tilt the engine towards the cylinder head cover to drain the oil into an appropriate container. Then screw up the engine oil plug.
• Unscrew the oil fill and dipstick. Fill with the recommended lubricating oil through the oil filler and check the oil level (no more than 600 ml).

Diagram shows engine oil plug location.

Precautions

• Recommended to replace oil when fuel is low to prevent overflow when tilting the engine.
• If oil overflows, wipe it off. Wash hands with soap/detergent and water after contact.
• Dispose of waste oil and containers according to environmental protection requirements. Store waste oil in a sealed container and deliver to a local waste oil recycling bin. Do not discard in dustbins or pour into water.

Maintenance of Air Filter

The air filter removes impurities and dust for clean air mixture, ensuring stable engine performance. A dirty filter reduces air capacity, causes abnormal combustion, and degrades performance.

DANGER: Do not use gasoline or cleaning agents with low ignition points to clean the filter element; fire or explosion may occur.

WARNING: Hard impurities entering the combustion chamber can cause fatal engine damage. Increase maintenance frequency in dusty areas.

CAUTION: Do not operate the engine without the air filter element installed, as it can accelerate wear and damage.

The air filter has a double-element structure (foam + paper). For inspection, remove the air filter casing and filter element. Replace damaged elements as needed, typically once during maintenance.

• Cleaning the foam filter element: Wash with cleaning agent, rinse with fresh water, and air dry before operation.
• Cleaning the paper filter element: Lightly beat the element several times and blow air from inside to outside with compressed air (not exceeding 30 psi). Do not use brushes.

Maintenance of Spark Plug (Model F6RTC)

Ensure spark plugs are clean and properly adjusted for normal engine operation.

1. Remove the spark plug by twisting counterclockwise.
2. Gently remove any carbon deposits from the plug.
3. Ensure the clearance is between 0.6-0.8 mm.

Diagram shows spark plug removal and adjustment gauge.

WARNING: Spark plugs must be securely tightened. Otherwise, the combustion chamber will not be airtight, leading to reduced engine power or failure.

Maintenance Before a Long-Term Shutdown

If the engine will not be used for an extended period, perform the following maintenance before shutdown:

1. Unscrew the fuel switch and the oil drain bolt at the bottom of the carburetor. Tighten the bolt after complete fuel release from the tank and carburetor.
2. Unscrew the oil drain bolt at the bottom of the crankcase to completely release lubricating oil. Then tighten the oil drain bolt.
3. Perform the following maintenance on the engine cylinder:
   • Remove the spark plug.
   • Pour a teaspoon (5cc) of clean engine oil into the cylinder.
   • Pull the start handle several times to distribute the oil in the cylinder.
   • Reinstall the spark plug.
   • Pull the start handle slowly until resistance is felt and the notch on the starter pulley aligns with the hole at the top of the recoil starter cover. This closes the valves, preventing moisture entry. Return the start handle gently.

   Diagram shows aligning the pulley notch with the cover hole.

4. Wipe off oil stains and dust from the external surface with a cleaning cloth. Remove dirt between cooling fins to keep the engine clean. Store the engine in a clean, dry, and ventilated location.
