Make sure that it’s placed on a dry surface and that it’s covered with a tarp or other waterproof material if it’s raining.

Regular maintenance is crucial to keep your generator running smoothly and safely. Make sure that you change the oil and filter as recommended by the manufacturer.

Check the air filter and clean it if necessary. Also, inspect the generator for any signs of wear and tear, and replace any damaged parts as needed.
