5. Installation and Replacement Instructions
Before beginning any maintenance, ensure the generator is turned off, cooled down, and disconnected from its power source to prevent accidental startup. Refer to your generator's owner's manual for detailed safety precautions and specific component locations.
5.1. Engine Oil Replacement
Description: Two black bottles of Generac Full Synthetic 5W-30 Engine Oil. Each bottle is labeled with 'GENERAC' and 'FULL SYNTHETIC SAE 5W-30 ENGINE OIL'. These are the two quarts of oil included in the maintenance kit.
- Locate the oil drain plug on your generator. Place a suitable container beneath it to collect used oil.
- Remove the drain plug and allow all old oil to drain completely.
- Reinstall the drain plug securely.
- Locate the oil fill cap. Using the provided funnel, slowly pour the two quarts of Generac Full Synthetic 5W-30 Engine Oil into the engine.
- Check the oil level using the dipstick, ensuring it is within the recommended range. Add more oil if necessary, but do not overfill.
- Securely replace the oil fill cap.
5.2. Oil Filter Replacement

- Using an oil filter wrench, carefully unscrew the old oil filter counter-clockwise and remove it.
- Apply a thin film of new engine oil to the rubber gasket of the new Generac oil filter.
- Screw on the new oil filter clockwise by hand until the gasket makes contact with the engine block. Then, tighten it an additional 1/2 to 3/4 turn. Do not overtighten.
- Wipe away any spilled oil with the shop towel.
5.3. Air Filter Replacement
Description: A cylindrical air filter composed of pleated paper filtration material with black rubber end caps. This filter is designed to capture airborne particles before they enter the engine.
