2. Informació de seguretat
ADVERTIMENT: Operating this generator improperly can lead to serious injury or death. Always follow safety guidelines.
- Perill de monòxid de carboni: Generators produce carbon monoxide, a colorless, odorless, poisonous gas. Operate the generator outdoors only, far away from windows, doors, and vents. Never operate in an enclosed area.
- Perill de descàrrega elèctrica: Do not operate the generator in wet conditions. Ensure all electrical connections are dry and properly grounded. Use ground fault circuit interrupter (GFCI) protected extension cords.
- Perill d'incendi: Gasoline is highly flammable. Refuel in a well-ventilated area with the engine off and cool. Do not smoke or allow open flames near the generator. Store fuel in approved containers away from living areas.
- Superfícies calentes: The generator engine and muffler become very hot during operation and remain hot for a period after shutdown. Avoid contact with hot surfaces to prevent burns.
- Parts mòbils: Keep hands, feet, hair, and clothing away from moving parts to prevent injury.
- Protecció auditiva: Prolonged exposure to generator noise can cause hearing damage. Wear appropriate hearing protection during operation.

4. Configuració
4.1 Desembalatge i muntatge
Carefully remove the generator from its packaging. Inspect for any shipping damage. Assembly typically involves attaching the wheels and handles. Refer to the assembly diagrams in the separate assembly guide for detailed steps.
4.2 Afegir oli de motor
- Col·loqueu el generador sobre una superfície plana.
- Localitzeu el tap/vareta d'ompliment d'oli.
- Remove the cap/dipstick and slowly add the recommended engine oil (refer to specifications for type and capacity) until it reaches the full mark on the dipstick. Do not overfill.
- Replace the oil fill cap/dipstick securely. The generator features pressure lubrication with low oil pressure shutdown for engine protection.
4.3 Afegir combustible
ADVERTIMENT: Use fresh, unleaded gasoline. Do not use E85 or mixed fuels. Refuel in a well-ventilated area with the engine off and cool.
- Assegureu-vos que el generador estigui apagat i fred.
- Obriu el tap del dipòsit de combustible.
- Slowly pour gasoline into the tank, being careful not to overfill. Leave space for fuel expansion. The tank capacity is 17 gallons.
- Tanqueu bé el tap del dipòsit de combustible.
4.4 Connexió de la bateria (per a l'arrencada elèctrica)
Connect the battery cables according to the instructions provided with the battery. Ensure correct polarity (positive to positive, negative to negative) to avoid electrical damage.
5. Instruccions de funcionament
5.1 Comprovacions prèvies a l'inici
- Comproveu el nivell d'oli del motor.
- Comproveu el nivell de combustible.
- Ensure all electrical loads are disconnected from the generator.
- Verify the generator is on a level surface and in a well-ventilated outdoor area.
5.2 Arrencada del motor (arrencada elèctrica)
- Gireu la vàlvula de combustible a la posició "ON".
- Moveu la palanca de l'estrangulador a la posició "CHOKE" (si el motor està fred).
- Insert the key into the ignition switch and turn it to the "START" position, or press the electric start button. Release once the engine starts.
- Un cop el motor s'hagi engegat, moveu lentament la palanca de l'estrangulador a la posició "RUN".
- Deixeu que el motor s'escalfi durant uns minuts abans de connectar les càrregues elèctriques.
5.3 Connexió de càrregues elèctriques
After the generator has warmed up, you can connect your electrical devices. Ensure the total wattage of connected devices does not exceed the generator's rated wattage (18,000 Watts) to prevent overload. The generator's automatic voltage regulator and less than 5% THD allow for safely running sensitive electronics.
- Plug your devices into the appropriate outlets on the control panel.
- If a circuit breaker trips, reduce the load, then reset the breaker by pushing it in.
5.4 Parar el motor
- Desconnecteu totes les càrregues elèctriques del generador.
- Deixeu que el motor funcioni durant uns minuts sense càrrega perquè es refredi.
- Turn the ignition key to the "OFF" position.
- Gireu la vàlvula de combustible a la posició "OFF".
6. Manteniment
Regular maintenance is crucial for the longevity and reliable operation of your generator. Perform checks at the intervals specified in the maintenance schedule (refer to a separate detailed maintenance guide if provided).
6.1 Oli de motor
- Comproveu el nivell d'oli abans de cada ús.
- Change oil after the first 20 hours of operation, then every 100 hours or annually, whichever comes first.
6.2 Filtre d'aire
The industrial 2-stage air cleaner should be inspected regularly and cleaned or replaced as needed, especially when operating in dusty conditions. A dirty air filter can reduce engine performance and lifespan.
