2.1 Vybalení a montáž
Carefully remove all components from the packaging. Ensure all parts listed in the accessories section are present. The package includes a 25 ft outlet hose, inlet metal filter screen, spark plug socket, force rod, wrench pressure cap, pipe joints, sealing rings, and shock pads. Note: PVC suction hose is not included and should be purchased separately if required.
2.2 Installing the Vibration-Damping Base
Install the pump's vibration-damping base to ensure stability during operation. Use the provided wrench to secure the base.
Video 1: Gasoline Engine Water Pump Startup Guide. This video demonstrates the initial setup steps, including installing the vibration-damping base, adding engine oil, and filling the fuel tank.
2.3 Doplnění motorového oleje
Unscrew the oil dipstick and add engine oil. The required amount is 0.5 liters (600 mL). Check the oil level using the dipstick; the oil level should be between the 'H' (maximum) and 'L' (minimum) marks. Insufficient oil will prevent the pump from starting and may damage the engine. Change the oil after the first 20 hours of operation or one month, and then every 50 hours thereafter.

2.4 Plnění palivové nádrže
Fill the fuel tank with unleaded gasoline. The tank capacity is 3 liters. Ensure the fuel cap is securely tightened after filling.
2.5 Installing the Outlet Hose
Connect the provided 25 ft outlet hose to the pump's outlet. Place the sealing gasket flat onto the pump connector, then connect the hose and ensure it is securely fastened with the hose clamp. Utáhněte hadici třamp securely using the nut wrench.
2.6 Installing the Inlet Hose
Install the filter screen onto the inlet hose (to prevent large debris from being sucked in and damaging the pump). Connect the inlet hose to the pump's inlet. Place the sealing gasket flat onto the pump connector and ensure it is securely locked. The inlet hose must be a plastic hose, not a fabric-reinforced hose, for the water inlet connection. Ensure the clamp is fully tightened. A loose clamp will cause air leaks and prevent the pump from priming. The maximum suction lift for this pump is 7 meters. Exceeding this vertical distance will prevent the pump from drawing water.

2.7 Naplnění čerpadla
Unscrew the priming port cap on the top of the pump. Fill the pump body completely with water until water flows out from the water outlet. This indicates the pump is full. Insufficient priming water will result in the pump's inability to draw water. Observe the water level and then tighten the priming port cap.

3.1 Startování motoru
- Ujistěte se, že je spínač zapalování v poloze „ON“.
- Set the choke to the "START" position. (Use the choke when starting a cold engine. If restarting the engine while it is still warm, the choke may not be needed.)
- Firmly hold the starter handle and pull the cord briskly to start the engine.
- Once the engine starts, gradually open the choke (set to "RUN").
- Move the throttle to the maximum position to achieve full engine power.

3.2 Zastavení motoru
To stop the engine, return the throttle to the idle position, then turn the ignition switch to the "OFF" position.
4. Údržba
Pravidelná údržba zajišťuje optimální výkon a prodlužuje životnost vašeho čerpadla.
- Motorový olej: Check the engine oil level before each use. Change the oil after the first 20 hours of operation or one month, and then every 50 hours thereafter. The oil capacity is 0.5L.
- Vzduchový filtr: Clean the air filter element every 50 hours or 10 hours under dusty conditions. Wash in high flash point solvent, squeeze dry, then dip in clean engine oil and squeeze out excess oil.
- Zapalovací svíčka: Inspect the spark plug regularly for wear or fouling. Replace if necessary.
- Palivo: Use unleaded gasoline. The fuel tank capacity is 3L.
- Připojení hadic: Regularly check all hose connections for tightness and ensure rubber O-rings are properly sealed to prevent air leaks.
- Oběžné kolo: Periodically check the pump's internal impeller for any foreign objects or debris that might cause jamming.

5. Řešení problémů
This section provides solutions to common issues you might encounter with your VEVOR Gasoline Powered Trash Pump.
5.1 Equipment Fails to Start
- Check if gasoline has been added to the fuel tank.
- Check if engine oil has been added and is at the middle mark on the dipstick. The oil capacity is 600 ml.
- Check that the ignition switch is in the "ON" position.
- Check if the spark plug is igniting properly. Use the provided spark plug wrench to remove the spark plug. Connect the igniter and ground it against a metal surface; a visible spark indicates normal operation.
- Check that the fuel valve is in the "ON" position.
- Check if the fuel line is clear. Remove the bolt at the bottom of the carburetor and check for fuel flow. Also, inspect the fuel hose connected to the carburetor for any kinks.
5.2 Equipment Fails to Pump Water During Operation
- Check if the pump chamber has been filled with priming water. Continue filling until water flows out from the water outlet.
- Check that the rubber O-rings on the inlet and outlet pipe connections are properly sealed and seated. Also, ensure the hose connections are secure and airtight.
- Use a plastic hose, not a fabric hose, for the water inlet connection.
- Ensure the suction lift does not exceed 7 meters.
5.3 Equipment Emits White Smoke During Operation
- Check for worn engine piston rings, which cause white smoke by burning oil.
- Check for overfilling of engine oil, which can lead to oil burning.
