Regular maintenance is key to long-term reliability. This includes checking and changing the oil regularly, using fresh fuel or adding a stabilizer for long-term storage, inspecting and cleaning the air filter, and periodically running the generator under load to keep the engine components lubricated and the battery charged (if equipped). Always consult your owner’s manual for the specific maintenance schedule recommended for your model in 2026.
