Quick Answer
To prepare a dual-fuel generator for long-term storage, drain the fuel tank, check and replace the air filter, and perform a tune-up to ensure it's in good working condition. It's also essential to store the generator in a dry, well-ventilated area. Consider using a fuel stabilizer to prevent degradation.
Pre-Storage Preparations
Drain the fuel tank to prevent fuel degradation and oxidation, which can lead to corrosion and gum formation. Use a siphon hose or a fuel pump to remove any remaining fuel. It’s recommended to drain the tank to 1/4 full or less. Next, check and replace the air filter to ensure optimal airflow and prevent dust buildup. For a dual-fuel generator, inspect and replace the carburetor and spark arrestor if necessary.
Storage and Maintenance
Store the generator in a dry, well-ventilated area, away from direct sunlight and moisture. Use a waterproof cover or tarp to protect the generator from the elements. Consider elevating the generator on a pallet or platform to improve airflow and prevent moisture accumulation. Perform a tune-up before storage to ensure the generator is in good working condition. This includes checking and replacing the spark plug, fuel lines, and other essential components.
Additional Tips and Considerations
Consider using a fuel stabilizer to prevent fuel degradation and oxidation during long-term storage. This can help extend the lifespan of the fuel and prevent costly repairs. If the generator has an oil reservoir, drain and replace the oil before storage to prevent contamination and corrosion. Finally, make sure to label the generator with its storage date and any relevant maintenance information to ensure easy identification and maintenance when it’s time to retrieve it.
