Add Fuel
Fuel must meet these requirements:
•Clean, fresh, unleaded gasoline.
•A minimum of 87 octane/87 AKI (91 RON). High altitude use, see High Altitude.
•Gasoline with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary butyl ether) is acceptable.
NOTICE
Avoid generator damage.
Failure to follow Operator’s Manual for fuel recommendations voids warranty.
•DO NOT use unapproved gasoline such as E85.
•DO NOT mix oil in gasoline.
•DO NOT modify engine to run on alternate fuels.
To protect the fuel system from gum formation, mix in a fuel stabilizer when adding fuel. See Storage. 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).
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
WHEN ADDING FUEL
•Turn generator OFF and let it cool at least 2 minutes before removing fuel cap. Loosen cap slowly to relieve pressure in tank.
•Fill fuel tank outdoors.
•DO NOT overfill tank. Allow space for fuel expansion.
•If fuel spills, wait until it evaporates before starting engine.
•Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition sources.
•DO NOT light a cigarette or smoke.
1.Clean area around fuel fill cap, remove cap.
2.Slowly add unleaded gasoline (A) to fuel tank (B). Be careful not to fill above the baffle (C). This allows adequate space for fuel expansion as shown.

3.Install fuel cap and let any spilled fuel evaporate before starting engine.
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. See a Briggs & Stratton Authorized Dealer for high altitude adjustment information. Operation of the engine at altitudes below 2,500 feet (762 meters) with the high altitude kit is not recommended.
