Bezpečnostní informace
Always prioritize safety when operating any machinery. Read and understand all safety warnings before use. Failure to follow these instructions may result in serious injury or property damage.
- Manipulace s palivem: Petrol is highly flammable. Always refuel in a well-ventilated area with the engine off and cool. Do not smoke or allow open flames near the pump.
- Výfukové plyny: The engine produces carbon monoxide, a colorless, odorless, poisonous gas. Operate the pump only in open, well-ventilated areas. Never operate indoors.
- Horké povrchy: The engine and pump components become very hot during operation. Avoid contact with hot surfaces to prevent burns. Allow the pump to cool before handling or servicing.
- Pohyblivé části: Keep hands, feet, and clothing away from moving parts such as the pull starter and any rotating components.
- Elektrická bezpečnost: While this is a petrol pump, ensure no electrical connections are exposed to water.
- Stabilní umístění: Čerpadlo vždy provozujte na stabilním a rovném povrchu, aby se nepřevrátilo.
- Osobní ochranné prostředky (OOP): Wear appropriate PPE, including eye protection and gloves, when operating or servicing the pump.
Nastavení
- Vybalení a kontrola: Carefully remove the pump from its packaging. Inspect for any shipping damage. Ensure all standard accessories are present: 1 engine tool, 2 hose couplings, 3 hose clamps, and 1 filter (2-inch suction basket).
- Přidejte motorový olej: Locate the oil filling screw. Fill the engine with the recommended 4-stroke engine oil (refer to engine manual for specific type and quantity) until the correct level is reached. The pump features oil deficiency protection, which will prevent operation if oil is too low.
- Přidat palivo: The pump operates on petrol. Locate the 3.6 L fuel tank. Fill the tank with fresh, clean petrol. Do not overfill. Securely close the fuel cap.
- Připojte hadice:
- Sací hadice: Attach a 2-inch suction hose to the suction connection of the pump using a hose coupling and clamp. Ensure the suction basket filter is attached to the end of the suction hose that will be submerged in the water source. Ensure all connections are airtight to prevent air leaks, which can affect priming.
- Vypouštěcí hadice: Attach a 2-inch discharge hose to the pressure connection of the pump using a hose coupling and clamp. Direct the discharge hose to where the water needs to be moved.
- Naplňte čerpadlo: The SEV-50X is a self-priming pump, but it requires initial priming. Locate the water filling nozzle on the pump casing. Remove the cap and fill the pump casing completely with water before starting the engine. Replace the cap securely.
- Umístění: Place the pump on a firm, level surface near the water source. Ensure the suction height does not exceed 8 meters for optimal performance.

Operace
- Předstartovní kontroly: Before each use, verify engine oil level, fuel level, and ensure all hose connections are secure and airtight. Confirm the pump casing is filled with water for priming.
- Startování motoru:
- Open the fuel valve (if applicable).
- Set the choke lever to the "CHOKE" position (for cold starts).
- Set the engine switch to "ON".
- Pevně a plynule táhněte za startovací lanko, dokud motor nenaskočí.
- Jakmile motor nastartuje, postupně přesuňte páčku sytiče do polohy „RUN“.
- Provoz čerpání: Once the engine is running, the pump will begin to draw water. Monitor the flow rate and ensure consistent operation. The pump has an operating time of approximately 2 hours on a full 3.6 L tank.
- Vypínání:
- If possible, allow the engine to idle for a few minutes to cool down.
- Set the engine switch to "OFF".
- Close the fuel valve (if applicable).
Údržba
Regular maintenance ensures the longevity and optimal performance of your KOSHIN SEV-50X pump.
