The function of a generator's lubrication system is to continuously deliver clean engine oil of sufficient quantity and appropriate temperature to the friction surfaces of all transmission parts while the engine is operating, thereby forming an oil film with lubricating effect. This not only effectively reduces friction between parts but also lowers power loss, ensuring the engine's service life while maintaining good working condition. Below is a summary of maintenance tips for the generator's lubrication system for reference: I. Selection and use of engine oil for the engine: 1. Oil viscosity: Select the viscosity grade according to the ambient temperature. 2. Oil quality grade (in accordance with standards set by the American Petroleum Institute): API SE, SP, SG or higher-grade oil. 3. The oil must be changed after the new engine has been run-in for 50 hours. Only by performing maintenance and oil changes as specified can the engine's service life be ensured. 4. Different grades of oil must not be mixed. II. Steps for replacing new oil: 1. Start the engine for a few minutes to increase the oil temperature, then stop the engine. 2. Place an oil pan under the oil drain plug, then remove the oil drain plug to allow all oil to drain out. 3. Check if the oil drain plug and gasket are damaged; replace them if necessary. 4. Reinstall the oil drain plug and gasket, ensuring no oil leakage! 5. Pour in 3.5 liters of new oil, then check if the oil level meets the requirement (the oil level should be between the upper and lower marks on the oil dipstick as shown in the figure). III. Replacement of the oil filter The oil filter must be replaced when the engine is cold. The replacement cycle should follow the requirements in the maintenance schedule. The replacement steps are as follows: 1. Use an oil filter wrench to remove the oil filter. 2. Apply a thin layer of oil to the surface of the gasket to fit the new oil filter. 3. Secure the new oil filter firmly. 4. Run the unit for a few minutes and check for oil leakage. Check the oil level in the oil pan and add oil to the specified level. The above is the maintenance of the generator's lubrication system. For more generator usage tips, you can contact us at any time. We will be happy to serve you.
