Fuel Use and Safety with the Generac iQ3500 Generator

Its 2.6-gallon fuel tank means the iQ3500 can run for an extended period without adding needless weight to what you have to carry to the campsite/jobsite.

You also don’t need to bother about opening the tank to check if it’s empty. The Generac iQ3500 digital display has a fuel gauge to notify you when your fuel levels are running low.

It can also show you an estimate of the remaining run time. This way, you can plan ahead of time to refill your tank.

The iQ3500 uses gasoline, so ensure you only refill with unleaded petrol. Also, don’t store any unused fuel close to the generator while it’s running. Store in a certified gasoline storage container. Check for leaks at all times.

It would be best if you never operated a generator indoors. All generators, including inverter generators like this, must be used in an area where there is adequate ventilation. This is to prevent dangerous carbon monoxide fumes from building up.
