What should be the maximum fill level when refueling the EU2000i Honda generator?

The maximum fill level for the EU2000i Honda generator should be at the upper limit mark indicated by a white ring. This mark serves as a guideline to prevent overfilling, which can lead to fuel spillage and potential fire hazards. It is crucial to adhere to this fill level because exceeding it could interfere with the generator's operation, especially if fuel expands during use or due to temperature changes. Filling to this recommended level ensures safe and efficient operation of the generator.

In contrast, filling the tank at the bottom or just below the fill neck would not utilize the generator's capacity effectively and could lead to inconvenience in operation due to less available fuel. Overfilling, which would be indicated as filling beyond the upper limit mark, poses significant safety risks and is detrimental to the longevity and functionality of the generator. Therefore, the importance of filling to the upper limit mark cannot be overstated for both safety and operational efficiency.
