2. Sikkerhedsinstruktioner
Always follow these safety precautions to reduce the risk of injury, electric shock, fire, and property damage.
2.1 Generel sikkerhed
- Læs manualen: Ensure you have read and understood all instructions before operating the generator.
- Kun udendørs brug: Operate the generator outdoors in a well-ventilated area. Never operate indoors or in enclosed spaces, as exhaust fumes contain carbon monoxide, which is deadly.
- Brændstofsikkerhed:
- Store fuel in approved containers in a well-ventilated area away from ignition sources.
- Do not refuel while the engine is running or hot. Allow the generator to cool down before refueling.
- Avoid spilling fuel. If spilled, wipe it up immediately and ensure the area is dry before starting the generator.
- Elektrisk sikkerhed:
- Brug ikke generatoren i våde forhold, og udsæt den ikke for regn.
- Ensure all electrical connections are secure and in good condition.
- Do not overload the generator. Refer to the specifications for maximum wattage.
- Use only grounded extension cords and appliances.
- Varme overflader: The generator's engine and muffler become very hot during operation and remain hot for some time after shutdown. Avoid contact with hot surfaces.
- Børn og kæledyr: Hold børn og kæledyr væk fra generatoren under drift.
2.2 Overbelastningsbeskyttelse
The generator is equipped with overload protection to prevent damage to the unit and connected devices. If the generator is overloaded, the overload indicator light will illuminate, and power output will cease. Reduce the load by disconnecting some appliances before restarting the generator.

4. Opsætning
Udfør følgende opsætningstrin før første brug:
- Udpakning: Tag forsigtigt generatoren ud af emballagen. Undersøg den for eventuelle forsendelsesskader.
- Tilsæt motorolie:
- Find oliepåfyldningsdækslet/målepinden.
- Add the recommended type and amount of engine oil (refer to specifications for oil type and capacity). Do not overfill.
- The oil warning indicator will prevent starting if the oil level is too low.
- Tilføj brændstof:
- Sørg for, at generatoren er slukket og afkølet.
- Open the fuel cap and carefully fill the fuel tank with unleaded gasoline. Do not overfill.
- Luk tankdækslet forsvarligt.
- Placering: Place the generator on a firm, level surface outdoors, away from windows, doors, and vents to prevent exhaust fumes from entering enclosed areas. Ensure adequate clearance around the generator for ventilation.
5. Betjeningsvejledning
5.1 Start af generatoren
- Sørg for, at generatoren står på en plan overflade, og at alle forbindelser er sikre.
- Turn the fuel valve to the "ON" position (if applicable).
- Move the Run/Off/Choke switch to the "CHOKE" position (for cold starts).
- Træk fast og jævnt i rekylstarterhåndtaget, indtil motoren starter.
- Once the engine starts, gradually move the Run/Off/Choke switch to the "RUN" position.

Figure 7: Easy Starting. This image shows a hand pulling the recoil starter cord, demonstrating the simple starting mechanism.
5.2 Tilslutning af apparater
- Allow the generator to warm up for a few minutes before connecting appliances.
- Plug in your devices to the appropriate AC or DC outlets.
- Do not exceed the generator's rated wattage (3200W continuous, 3500W peak). Overloading can damage the generator and connected devices.
5.3 ECO-tilstand
The ECO mode switch allows the generator to automatically adjust engine speed to match the load, reducing fuel consumption and noise levels when less power is required. For maximum power output, ensure ECO mode is switched off.
