1. Ensure your quad is on level ground. Ensure the quad is turned off and has had time to cool down.
2. Locate the oil sight glass. The oil sight glass is located on the left side of the crankcase.
3. Remove the oil fill plug. The oil fill plug is located on the right side of the crankcase.
4. Check the oil level. The oil level should be between the "L" and "F" marks on the oil sight glass. If the oil level is below the "L" mark, add engine oil of recommended grade and viscosity to reach the correct level.
5. Replace the oil fill plug. Tighten the oil fill plug to 10-12 ft-lbs.
