5. Configuració
5.1. Desembalatge i col·locació
- Traieu amb cura la bomba i tots els accessoris de l'embalatge.
- Place the pump on a stable, level, and well-ventilated surface, away from flammable materials.
5.2. Connexió de mànegues
- Attach the suction filter to the end of the suction hose. Ensure the filter is fully submerged in the water source during operation.
- Connect the suction hose to the pump's 1-inch suction port. Secure it tightly with a hose clamp to prevent air leaks. Air leaks in the suction line will prevent the pump from priming.
- Connect the discharge hose to the pump's 1-inch discharge port. Secure it with a hose clamp.
5.3. Fueling the Engine
The EBERTH GW2-ERWP10 uses a 2-stroke engine, requiring a specific gasoline-oil mixture.
- Prepare a fuel mixture of unleaded gasoline and 2-stroke engine oil at a ratio specified by the engine oil manufacturer (typically 25:1 or 50:1). Use the provided mixing bottle for accuracy.
- Assegureu-vos que el motor estigui apagat i fred.
- Desenrosqueu la tapa del dipòsit de combustible.
- Carefully pour the mixed fuel into the fuel tank (0.7-liter capacity), avoiding overfilling.
- Torneu a col·locar el tap del dipòsit de combustible de manera segura.

5.4. Aclarint la bomba
The pump must be primed with water before starting the engine to ensure proper operation and prevent damage.
- Locate the priming port cap on top of the pump housing.
- Unscrew the priming port cap.
- Slowly fill the pump housing with clean water until it overflows.
- Securely replace the priming port cap.

6. Instruccions de funcionament
6.1. Arrencada del motor
- Ensure the pump is primed and all hose connections are secure.
- Move the choke lever to the "CLOSED" or "START" position (for cold starts). For a warm engine, the choke may not be necessary.
- Set the throttle lever to a mid-range position.
- Grasp the pull starter handle firmly and pull it slowly until resistance is felt, then pull quickly and smoothly. Repeat until the engine starts.
- Once the engine starts, gradually move the choke lever to the "OPEN" or "RUN" position as the engine warms up.

6.2. Ajust del cabal
The water flow rate can be continuously adjusted using the throttle lever.
- Move the throttle lever towards "FAST" for higher engine RPM and maximum flow.
- Move the throttle lever towards "SLOW" for lower engine RPM and reduced flow.

6.3. Aturar el motor
- Moveu la palanca de l'accelerador a la posició "SLOW" o "IDLE".
- Gireu l'interruptor del motor a la posició "OFF".

7. Manteniment
Un manteniment regular garanteix un rendiment òptim i allarga la vida útil de la bomba.
- Després de cada ús:
- Drain all water from the pump housing by removing the drain plug.
- Clean the suction filter to remove any debris.
- Wipe down the exterior of the pump.
- Emmagatzematge de combustible: If storing the pump for an extended period (more than 30 days), drain the fuel tank and carburetor to prevent fuel degradation and starting issues.
- Bujía: Inspect and clean the spark plug periodically. Replace if worn or fouled. Use the provided spark plug wrench.
