2. Sikkerhedsoplysninger
Operating a generator safely is crucial. Always follow these guidelines to prevent accidents and ensure safe operation.
2.1 Carbon Monoxide (CO) Alert System
This generator is equipped with CO Alert technology, which automatically shuts down the unit if unsafe carbon monoxide levels are detected around the generator. This system is designed to enhance safety but does not replace the need for proper ventilation.
- Brug aldrig generatoren indendørs eller i lukkede rum. Carbon monoxide is a colorless, odorless gas that can be fatal.
- Ensure adequate ventilation when operating outdoors. Position the generator far away from windows, doors, and vents.
- If the CO Alert system activates and shuts down the generator, move the generator to an open-air location and allow it to ventilate before attempting to restart.
