Add Engine Oil
We recommend using FIRMAN SAE 10W-30 API SJ oil for best performance. Other high-quality
detergent oils (API SJ or higher) are acceptable. Do not use special additives. Ambient temperature
determines the proper oil viscosity for the engine. Use the chart to select the proper oil for the
outdoor temperature range expected.
NOTICE
Do not attempt to crank or start the engine before it has been properly filled with the
recommended type and amount of oil. Damage due to operation with no oil will void your warranty.
