2. Informació de seguretat
Operating a generator safely is paramount. Always follow these guidelines to prevent serious injury or death.
Seguretat del monòxid de carboni (CO)
Generators produce carbon monoxide, a colorless, odorless, poisonous gas. Operating a generator indoors or in partially enclosed spaces can lead to fatal carbon monoxide poisoning.
- SEMPRE operate the generator outdoors in an open area, away from windows, doors, and vents.
- Ensure exhaust fumes are directed away from occupied buildings.
- Install battery-operated carbon monoxide alarms in your home or any enclosed space where the generator's exhaust could potentially enter.

Your FIRMAN T12071 generator is equipped with CO Alert technology. This system automatically shuts down the engine if unsafe levels of carbon monoxide are detected around the generator or if a CO Alert system fault occurs. Refer to the CO Indicator Light section for more details.
