ADDING FUEL
Add fuel to the generator in a well-ventilated area. Never refuel the
engine inside a building where gasoline fumes may reach flames or
sparks. Keep gasoline away from appliance pilot lights, barbecues,
electric appliances, power tools, etc. Spilled fuel is not only a fire
hazard, it causes environmental damage. Wipe up spills immediately.
This engine is certified to operate on unleaded gasoline with a pump
octane rating of 86 or higher. Unleaded gasoline produces fewer
engine and spark plug deposits and extends exhaust system life.
Gasoline is highly flammable and explosive.
You can be burned or seriously injured when handling fuel.
Stop the engine and keep heat, sparks, and flame away.
Handle fuel only outdoors.
Wipe up spills immediately.
1. Remove the fuel tank cap.
2. Fuel carefully to avoid spilling fuel.
Do not fill the fuel tank above the
upper limit mark on the fuel strainer.
