Indledende opsætning
Follow these steps to prepare the generator for its first use:
1. Wheel and Foot Assembly
The generator comes with wheels and support feet that need to be assembled for easy transport and stability.
Demonstration video on assembling the wheels and support feet of the generator. This video shows how to securely attach the wheels and supports to ensure the unit's mobility and stability.
2. Påfyldning af motorolie
Before the first start-up, it is crucial to add engine oil. Use SAE 10W-30 engine oil. The oil capacity is 0.6 liters.
- Unscrew the oil cap/dipstick.
- Use a funnel to slowly pour oil into the reservoir until the level indicated on the dipstick is reached (do not exceed the "H" position).
- Screw the oil cap back on securely.
Video illustrating the procedure for adding engine oil to the generator. It shows how to unscrew the dipstick, pour the oil, and check the correct level.
3. Påfyldning af brændstof
Add unleaded gasoline to the fuel tank. The tank capacity is 18 liters.
- Sørg for, at motoren er slukket og afkølet.
- Åbn brændstoftankens dæksel.
- Slowly pour gasoline into the tank, avoiding overfilling.
- Luk brændstoftankens dæksel forsvarligt.

4. Battery Connection (for electric start, if applicable)
If your model includes electric start, connect the battery as follows:
- Locate the battery and connection cables.
- Connect the positive (+) (red) cable to the positive terminal of the battery.
- Connect the negative (-) (black) cable to the negative terminal of the battery.
- Sørg for, at forbindelserne er sikre.

2. Tilslutning af enheder
After starting the generator, you can connect electrical devices to the available outlets (2x16A).
- Ensure devices are turned off before connecting them.
- Insert the device's plug into one of the AC 230V outlets.
- Tænd for enheden.
3. Overvågningsdrift
The control panel features a 3-function digital display to monitor operating parameters:
- Voltmeter: Angiver udgangsvolumentage (230V).
- Frekvensmåler: Shows the frequency (50 Hz).
- Timetæller: Records total operating hours for maintenance scheduling.
Opretholdelse
Regular maintenance is essential to prolong the generator's life and ensure its safe operation.
1. Oil Check and Change
Check the oil level before each use. Change the oil after the first 20 hours of operation, and then every 100 hours or every 6 months.
Video illustrating the maintenance guide for a gasoline generator, with a focus on checking and replacing engine oil.
2. Rengøring af luftfilter
Clean the air filter every 50 hours of operation or more frequently in dusty environments.
- Fjern luftfilterdækslet.
- Fjern filterelementet.
- Clean the element with compressed air or wash it with soapy water and let it dry completely.
- Reinstall the filter element and cover.
3. Tændrørsinspektion
Inspect the spark plug every 100 hours of operation. Clean or replace it as needed.
- Fjern tændrørshætten.
- Use a spark plug wrench to unscrew and remove the spark plug.
- Check the electrode for wear or carbon deposits. Clean or replace if necessary.
- Sæt tændrøret og hætten på igen.
