Operation and Storage

To ensure a long service life of the unit, follow simple maintenance rules: monitor oil and fuel levels, clean filters and spark plugs in a timely manner, and for long-term storage, drain residual fuel and replace oil if necessary. The generator should be stored in a dry room, protected from direct sunlight and moisture.

Frequently Asked Questions

How to choose generator power?

Calculate the total consumption of all appliances you plan to connect, and add 20–30% reserve to cover starting peaks and for backup.

Gasoline or diesel?

If you plan periodic use for a few hours, a gasoline generator will be more convenient and cheaper to purchase. For continuous and intensive operation, it is better to choose diesel units due to their fuel efficiency and long service life.

Do weather conditions affect it?

Yes. High temperatures can cause overheating, and very low temperatures (below -20℃) can make starting difficult. Use in rain or snow requires a canopy or moisture protection to avoid short circuits.

How to prepare for long-term storage?

• Drain residual fuel
• Clean filters and spark plugs
• Replace oil if necessary
