Impostare
1. Disimballaggio e ispezione
Carefully remove all components from the packaging. Inspect for any shipping damage. If any parts are damaged or missing, do not operate the pump and contact customer support.

3. Aggiungere olio motore
The engine is shipped without oil. Before starting, add the supplied engine oil using the oil funnel. Locate the oil fill cap/dipstick, remove it, and slowly pour oil until it reaches the upper mark on the dipstick. Do not overfill.
4. Aggiungere carburante
Fill the fuel tank with fresh, unleaded gasoline (minimum 87 octane). Do not use E85 fuel. Ensure the fuel cap is securely tightened after filling.

5. Collegare i tubi flessibili
Connect the suction hose to the pump's inlet port (often color-coded, e.g., blue for inlet). Attach the strainer to the end of the suction hose. Connect the discharge hose to the pump's outlet port (often color-coded, e.g., green for outlet). Ensure all connections are tight to prevent air leaks, which can affect priming and pump performance.

6. Adescamento della pompa
The Generac 6821 features a custom funnel design for quick and easy priming. Remove the prime cap located on top of the pump housing. Fill the pump housing with clean water until it overflows. Replace the prime cap securely. The pump must be primed before each use to ensure it can draw water effectively.

Istruzioni per l'uso
1. Avviamento del motore
- Ensure the pump is properly primed and all hoses are connected.
- Place the suction hose with the strainer into the water source.
- Ruotare la valvola del carburante in posizione 'ON'.
- Spostare la leva dello starter in posizione 'CHOKE' (se il motore è freddo).
- Ruotare l'interruttore del motore in posizione 'ON'.
- Tirare la maniglia dell'avviamento a strappo con decisione e dolcezza finché il motore non si avvia.
- Una volta avviato il motore, spostare gradualmente la leva dello starter in posizione "RUN".
2. Durante il funzionamento
Monitor the pump for consistent water flow and listen for any unusual noises. Ensure the suction hose remains submerged in water to prevent the pump from running dry, which can cause damage.
3. Arresto del motore
- Portare l'interruttore del motore in posizione "OFF".
- Ruotare la valvola del carburante in posizione 'OFF'.
- Allow the engine to cool before handling or storing.
Manutenzione
Una manutenzione regolare garantisce prestazioni ottimali e prolunga la durata della pompa.
Olio motore
Check the engine oil level before each use. Change the oil after the first 5 hours of operation, and then every 50 hours or annually, whichever comes first.
Filtro dell'aria
Inspect the air filter regularly and clean or replace it as needed, especially when operating in dusty conditions.
Candela
Inspect the spark plug annually or every 100 hours. Clean or replace if necessary, ensuring the correct gap.
Pump Housing and Impeller
Periodically inspect the pump housing and impeller for debris or wear. Clean out any blockages to maintain efficient flow.
Magazzinaggio
For long-term storage, drain the fuel tank and carburetor. Remove the spark plug and pour a small amount of engine oil into the cylinder, then pull the recoil starter a few times to distribute the oil. Clean the exterior of the pump and store it in a dry, protected area.
Risoluzione dei problemi
