Briggs & Stratton 30473 Generator Location, Fuel Recommendations, WARNING, High Altitude, When Adding or Draining Fuel, Fuel must meet these requirements:

Generator Location

WARNING Exhaust heat/gases could ignite combustibles or structures resulting in death, serious injury and/or property damage.

•Keep at least 5 feet (152 cm) of clearance on all sides of generator including overhead.

For proper clearance and air movement, place generator outdoors in an area that will not accumulate deadly exhaust gas. DO NOT place generator where exhaust gas (A, Figure

1)could accumulate and enter inside or be drawn into a potentially occupied building. Ensure exhaust gas is kept away from any windows, doors, ventilation intakes, or other openings that can allow exhaust gas to collect in a confined area. Prevailing winds and air currents should be taken into consideration when positioning generator.

Fuel Recommendations

Fuel must meet these requirements:

•Clean. fresh, unleaded gasoline

•A minimum of 87 octane/87 AKI (91 RON)

•Gasoline with up to 10% ethanol (gasohol) or up to 15%MTBE (methyl tertiary butyl ether) is acceptable.

NOTICE: Do not use unapproved gasoline, such as E85. Do not mix oil in gasoline or modify the engine to run on alternate fuels. Failure to follow will result in damage to the engine and/or generator and will void the warranty.

To protect the fuel system from gum formation, mix in a fuel stabilizer when adding fuel. All fuel is not the same. If you experience starting or performance problems after using fuel, switch to a different fuel provider or change brands. This engine is certified to operate on gasoline. The emission control system for this engine is EM (Engine Modifications).

	When Adding or Draining Fuel
	•	Turn generator engine OFF and let it cool at least 2
		min	tes before removing fuel cap. Loosen cap slowly to
		relieve press re in tank.
	•	Fill	r rain tank outdoors.
	•	DO NOT overfill tank. Allow space for fuel expansion.
	•	If fuel spills, wait until it evaporates before starting
		engine.
A	•	Keep fuel away from sparks, open flames, pilot lights,
		heat, and other ignition sources.
	•	Check fuel lines, tank, cap, and fittings frequently for
		cracks or leaks. Replace if necessary.

High Altitude

At altitudes over 5,000 feet (1524 meters), a minimum 85 octane / 85 AKI (89 RON) gasoline is acceptable. To remain emissions compliant, high altitude adjustment is required. Operation without this adjustment will cause decreased performance, increased fuel consumption, and increased emissions.

Operation of the generator at altitudes below 2,500 feet (762 meters) with the high altitude kit is not recommended.
